FORWARD

It is becoming more and more widely accepted that Ice Ages coincide with the passage of the Solar System through the spiral arms of our galaxy. It therefore occurred to me to wonder what would become of a species that evolved intelligence just before their planet's transit of a gas-cloud far denser than the one in Orion which the Earth has recently—in cosmic terms—traversed.

In my attempt to invent its history I have frequently relied on the advice of Mr. Ian Ridpath, whose prompt and generous aid I gratefully acknowledge.

PROLOGUE

In the center of the huge rotating artificial globe the folk assembled to await retelling of an age-old story.

Before them swam a blur of light. Around them was a waft of pheromones. Then sound began, and images took form.

A sun bloomed, with its retinue of planets, moons and comets. One was the budworld. Slowly—yet how much more swiftly than in the real past!—a wild planet curved out of space towards what had once been their race's home.

"If only they had known...!" somebody murmured.

"But they did not!" the instructor stressed. "Remember that, throughout the whole of what you are to watch! You are not here to pity them, but to admire!"

THE CRUCIBLE OF TIME

PART ONE

THE FIRE IS LIT

I

Now the sun was down, the barq was growing tired. The current opposing her was swift, and there was a real risk she might be driven against the rocks that beset the channel and puncture her gas-bladders. After countless attempts to sting her into more vigorous activity, the steersman laid by his goad and grumpily tipped into her maw the last barrelful of the fermented fish and seaweed which served to nourish boat, crew and passengers alike. Waiting for the belch that would signal its digestion, he noticed Jing watching from her saddle of lashed planks, as anxious as though his weather-sense were predicting storms, and laughed.

"You won't be a-dream before we get where we're bound!" he promised in the coarse northern speech which the foreigner had scarcely yet attuned his hearing to.

It was hard to realize there was anywhere worth traveling to in this barren landscape. Most of the time the shore was veiled with rags of fog, because the water was so much warmer than the air. What a place to choose for studying the sky! Even though, with the sun setting so much earlier every day, it was possible to believe in the legend which had lured him hither: a night that lasted almost half a year. Not that there could ever be total darkness; here, as everywhere, the Bridge of Heaven—what these northerners called the Maker's Sling—curved in its gleaming arc across the welkin. And, near the horizon, less familiar and altogether awe-inspiring, the New Star was framed in its irregular square of utter black like a jewel on a pad of swart-fur.

But neither that celestial mystery, nor the prospect of going hungry, was what preyed most on the mind of Ayi-Huat Jing, court astrologer and envoy plenipotentiary of His Most Puissant Majesty Waw-Yint, Lord of the Five-Score Islands of Ntah. Compelled by his sworn oath, a whole miserable year ago he had set forth in state, riding the finest mount in his master's herd and accompanied by forty prongsmen and ten banners inscribed with his rank and status. His mission was to seek out wise folk beyond the mountains that ringed the Lake of Ntah and inquire of them the meaning of the New Star. His countrymen had long imagined that they understood the reason why the heavens changed—for change they definitely did. He carried with him a fat roll of parchment sheets on which had been copied star-maps depicting the sky on the accession-dates of the last score rulers of Ntah, and on the date of every eclipse during their reigns. Sixteen stars were shown on the most recent which in olden times had not been there, and marks recorded others which had appeared and faded in a matter of days. But there had never been one so brilliant, or so long-lasting, or in so black a patch of sky. According to the philosophers of Ntah, right action was reflected in heaven, and sufficient of it earned a diminution of the darkness. Eventually, they promised, the time would come when the heavens would be as bright by night as by day.

And it had happened, and it had ceased, and everyone was grievously disturbed, for blight and plague had followed what should have been a sign of unprecedented good fortune...

Jing's journey had been fruitless so far, but it was not yet doomed to failure. His store of pearlseeds from the Lake was less than half-exhausted, for they grew stranger and more precious as he traveled, exchangeable for more food and longer lodging, and he had clung to his roll of maps even though in all the lands and cities he had visited he had met only one person who appeared to grasp their significance. He had expected students of heaven-lore as dedicated as himself, libraries too— albeit in alien script on unfamiliar materials—because tradition told of merchants from Geys and Yown and Elgwim who had brought amazing horns, hides, seeds and spices along with boastful tales about the riches of their homelands. What he had actually found...

Half-starved mud-scrabblers incapable of distinguishing dream from reality, ascribing crop-failure, blight and murrain to supernatural beings, imagining they could protect themselves by sacrificing most of what remained to them—whereupon, of course, weakness and fatigue allowed dreams to invade their minds ever further. Madness, madness! Why did not everybody know that the heavens bodied forth an impersonal record of the world below, neither more nor less? How could anybody, in these modern times, credit a god prepared to launch missiles at random with a view to killing people? The welkin shed messages, not murder!

His whole course since leaving Ntah had been a succession of horrid shocks. Geys, one of the first cities he had planned to visit, stood abandoned and overgrown, for—so he was told—a flaming prong from the sky had struck a nearby hill and everyone had fled in panic. Moreover, of the escorts and banners who had set out with him (any other of the court officers would have had concubines as well, but Jing was obliged by his calling to accept celibacy) most had deserted on finding how squalid was the world beyond the mountains, while not a few had succumbed, as had his mount, to bad food or foul water.

One alone had survived to accompany him into the branchways of the great city Forb, where first he had encountered learned men as he regarded learning. Yet they were parasites, Jing felt, upon their city's past, disdainful of sky-shown truths, able only to expound concerning inscriptions and petty relics which they claimed to be older than anything elsewhere. Jing was reticently doubtful, but it was impolitic to speak his mind, partly because he was unfluent in the speech of that region, partly because its masters exercised very real power which he had no wish to see turned against Ntah, and chiefly because of the nature of that power.

His tallness, and the fact that his companion was taller yet, made him remarkable. The nobility bade him to banquets and festivities as a curiosity. It was a time of dearth, as he had discovered on his way; nonetheless, the fare at such events was lavish. It followed that the lords of Forb must control vast domains—not, however, vast enough to satisfy them, as was apparent from the way they spent all their tune maneuvering for advantage over one another, and instructed their interpreters to ply Jing with questions concerning weaponry. They were prepared to descend as far as spreading disease among a rival's crops, than which only the use of wildfire could be baser. Were such monsters to be let loose in the peaceful region of Ntah...!

Shuddering, yet determined to pursue his quest, Jing eventually discovered the secret of their dominance. It lay not in their armies, nor their treasuries. It consisted in the deliberate and systematic exploitation of the dreams of those less well-to-do than themselves, a possibility which had never occurred to him, and which the language barrier prevented him from comprehending until a lordling he had disappointed in his hope of brand-new armaments set sacerdotes upon him at his lodgings.

He had frequently seen their like bringing up the tail-end of a noble's retinue, always gaunt in a manner that contrasted greatly with the glistening plumpness of their masters, and initially he had assumed them to be nothing more than servants: scribes, perhaps, or accountants, though it was hard to conceive how such dream-prone starvelings could be relied on.

Acting, however, more like persons of authority than underlings, these visitors interrogated him concerning Ntah. Pleased to meet anyone prepared to discuss what he thought of as serious subjects, Jing answered honestly, hoping to show that the relationship between Ntah and its satrapies, being sustained by trade in information concerning what the heavens portended, was more civilized than rule by force.

Did he not—they responded in shocked tones—acknowledge the ex-ample of the Maker of All, who daily surveyed the world with His all-seeing eye, the sun, and nightly dispatched fiery bolts by way of warning that His way must be adhered to on pain of uttermost destruction? Was he not aware that the arc in the sky was the Maker's sling, that the Maker's mantle was what lighted the heavens with the glimmer of marvelous draped colors? Then he was in peril of imminent disaster, and were he still to be in Forb when it overtook him, scores-of-scores of innocent people would be caught up in the catastrophe! He must leave the city at once, or they would execute the Maker's will upon him themselves!

Jing's lifelong faith in the beneficence of the universe had been shaken, but he was not about to enter someone else's fever-dream. He did his best to scorn the warning—until the day when his sole surviving escort, Drakh, was set on by an unknown gang and attacked with weapons such as would never have been permitted in Ntah: prongs steeped in the ichor from a rotting carcass, warranted to poison the slightest cut even though it was not deep enough to let out life.

Now Drakh lay delirious beside him, as for days past, shivering less at the bitter air than the racking of his sickness. He would have been dead but that Jing's treelord—a Shreeban, well accustomed to being shunned by his Forbish neighbors and mocked by their children when he went abroad—had called a doctor, said to breed the best cleanlickers in the city.

And the doctor had saved not only Drakh's life (so far, Jing amended wryly, for the licker was weakening and the sorbers it passed repeatedly over his wound were turning yellow) but also the mission they had been sent on. Forgetful of his other clients, he had sat for days greedily studying Jing's star-maps, mentioning now and then that such-and-such a one of his forebears had claimed to be older than this or that star: heretical information in Forb where the Creation was supposed to have been perfect from the Beginning.

How could such dream-spawned nonsense survive the appearance of the New Star, which for a score of nights had outshone the Bridge of Heaven, and still after four years loomed brighter than anything except the sun and moon?

It might well not, explained the doctor. As people became more prosperous and better fed, so they naturally grew more capable of telling dream from fact. This led them to mock the sacerdotes, whose power had been decreasing from generation to generation despite their deliberate self-privation. Now they were reduced to claiming that the New Star was a delusion due to the forces of evil, which—they said—dwelt in that bleak zone from which the Maker had banned all stars as a reminder of the lightless eternity to which He could condemn transgressors. But there were those who maintained that one supremely righteous person was to be born—now: must have been—who could hold up a lamp where the Maker had decreed darkness, and lead folk out of mental enslavement.

Looking at the glowplants that draped the walls of his rented home, Jing prompted him to more revelations. Were there none here in the north who studied star-lore?

The chief of them, the doctor said, had taken refuge with the Count of Thorn. Branded by the sacerdotes as victim of a divine curse, that lord had retreated to an arctic fastness where hot springs bubbled out of frozen ground—clear proof, said the sacerdotes, of his commitment to evil, for in the absence of sunlight water could be heated only by fire, the prerogative of the Maker: hence those who usurped it must be on His adversary's side. Where Thorn had gone, besides, report held that a night might last for half a year, and evil dwelt in darkness, did it not? Yet it was also rumored that those who had followed him were prosperous while everywhere else epidemics were tramping in the pad-marks of famine...

"There has been some land of change," the doctor whispered. "My best remedies have ceased to work, and many babies bud off dead or twisted. Also there is a taint in this year's nuts, and it seems to drive folk mad. If I had more courage I too would go where Thorn has gone ... Pay me nothing for the care of your man. Promise only to send news of what they have found out in that ice-bound country. It is a place of ancient wisdom which the sacerdotes interdicted, saying it was dream-stuff. I think they were in error in that also."

Now Jing, so weary he too was having trouble telling dream from fact, was come to Castle Thorn at the head of the warm channel. The fog parted. The moon was rising, gibbous in its third quarter, and as usual its dark part sparkled.

II

If Forb was old, then Castle Thorn was antique. Guarding the entrance to a bowl-shaped valley, it loomed as large as a city in its own right—not that its whole bulk could be seen from the outcrop of rock serving it as a wharf, despite the glowplants which outlined it at a distance, for its defenses were elaborate and far-reaching. On either bank bomas trembled ready to collapse their spiky branches, while masses of clingweed parted only in response to blasting on a high-pitched whistle. Prongsmen came to hitch the barq's mooring-tentacles, accompanied by enormous canifangs.

Just before docking Jing had realized that a range of hills on the horizon was gleaming pure white in the moonshine. He had said, "Snow already?"

And the steersman had grunted, "Always."

So there truly was a place where ice might defy summer. For the first time Jing felt in his inmost tubules how far he was from home.

But there was no time for reflection. A voice was calling to him in city-Forbish: "Hail to the foreigner! I'm told your prongsman is sick. As soon as he's ashore I'll see what I can do for him. I'm Scholar Twig, by the way."

Who was a person of advanced years, his tubby shortness—characteristic of these northerners—aggravated by loss of pressure in his bracing tubules, but his expression alert and manner brisk. Grateful, for Twig was the name the doctor had told him to ask for, Jing returned the greeting.

"How you know I coming?" he demanded.

"Oh, you've made news over half the continent," was the prompt reply. "Sorry we don't have anyone around who speaks Ntahish, but until you showed up most people thought your homeland was just a legend, you know? Say, is it true you have star-maps going back to the Beginning? How soon can I look at them?"

Groping his way through the rush of words, Jing recalled the protocol which attended ambassadors to Ntah.

"Not I must at once pay respect the lord?"

"He's dining in the great hall. You'll meet him in a little. First let me present my colleagues. This is Hedge, this is Bush, this is—"

It was impossible to register so many strangers when he was so fatigued. "But my man-at-arms...?" he ventured.

"Ah, what am I thinking of? Of course, we must get him and you to quarters right away!"

Detailing some junior aides to carry Drakh, Twig led the way at half a trot.

Jing could have wished to move more slowly, because nothing had prepared him for the luxury he discerned all about him. The very stones were warm underpad. The gnarled trunks of the castle were thicker than any he had ever seen, and even at this season they were garlanded with scores of useful secondary plants. Steaming ponds rippled to the presence of fish, while fruit he had not tasted the like of since leaving home dangled from overhanging boughs, and everywhere trailed luminescent vines. Through gaps between the boles, as he ascended branchways in Twig's wake, he caught glimpses of a landscape which reminded him achingly of parts of Ntah. He had thought in terms of a mere clawhold on survival, but the valley must support a considerable population. He saw three villages, each with a score of homes, surrounded by barns and clamps large enough to store food for a year—and that was only on one side of the castle. Amazing! His spirits rose.

And further still when Drakh was laid in a comfortable crotch and a maid brought warm drink. Passing him a huskful, Twig said dryly, "In case you're superstitious about fire, it's untouched by flame. We keep the bags in a hot spring."

Jing's people cared little about fire one way or the other, so he forbore to reply. Whatever its nature, the drink effectively drove away dreams. Meanwhile Twig was inspecting Drakh's licker and saying in disgust, "This should have been changed days ago! Here!"—to the maid—"take it away and bring one of my own at once. They're of the same stock," he added to Jing, "though here we have fewer outlandish poisons they can learn to cope with. Faugh! They do stink, though, don't they, at that stage?"

Now that Jing's perceptions were renewed, he had realized that the very air inside the castle stank—something to do with the hot springs, possibly. Never mind. He posed a key question.

"Drakh will live, yes?"

"I'm not a specialist in foreign sicknesses, you know! But ... Yes, very probably. I'll send for juice which can be poured between his mandibles. Wouldn't care to offer him solid food in his condition."

Jing nodded sober agreement. Reflex might make him bite off his own limbs.

"Are those your maps?" Twig went on, indicating the rolled parchments. "How I want to examine them! But you must be hungry. Come on. I'll show you to the hall."

There, at its very center, the true antiquity of the castle was revealed. Despite the dense clusters of glowplants which draped the walls, Jing could discern how the ever-swelling boles of its constituent bravetrees had lifted many huge rocks to four or five tunes his own height. Some of them leaned dangerously inward where the trunks arched together. None of the company, however, seemed to be worrying about what might happen if they tumbled down. Perhaps there were no quakes in this frozen zone; the land might stiffen here, as water did, the year around. Yet it was so warm...

He postponed such mysteries in order to take in his surroundings.

The body of the hall was set with carefully tended trencher-stumps, many more than sufficed for the diners, who were three or at most four score in number. Not only were the stumps plumper than any Jing had seen in Forb; they were plentifully garnished with fruit and fungi and strips of meat and fish, while a channel of hollow stems ran past them full of the same liquor Twig had given him. Entrances were at east and west. At the south end a line of peasants waited for their dole: a slice of trencher-wood nipped off by a contemptuous kitchener and a clawful of what had been dismissed by diners at the north. Jing repressed a gasp. Never, even in Ntah, had he seen such lavish hospitality. It was a wonder that the Count's enemies in Forb had not already marched to deprive him of his riches.

"So many peasants isn't usual," murmured Twig.

"I believe well!" Jing exclaimed. "Plainly did I see villages with land enough and many high barns!"

"Except that on the land the trencher-plants are failing," Twig said, still softly. "Take one of these and transplant it outside, and it turns rotten-yellow. But save your questions until you've fed, or you'll spend a dream-haunted night. Come this way."

Jing complied, completing his survey of the hall. In a space at the center, children as yet unable to raise themselves upright were playing with a litter of baby canifangs, whose claws were already sharp. Now and then that led to squalling, whereupon a nursh would run to the defense of its charge, mutely seeking a grin of approval from the fathers who sat to left and right. Each had a female companion, and if the latter were in bud made great show of providing for her, but otherwise merely allowed her to bite off a few scraps.

And at the north end sat the Count himself, flanked by two girls, both pretty in the plump northern manner, but neither budding.

The Count was as unlike what Jing had been led to expect as was his castle. He had been convinced by the doctor that he was to meet a great patron of learning, more concerned with wisdom than material wealth. What he saw was a gross figure so far gone in self-indulgence that he required a sitting-pit, whose only concession to stylish behavior was that instead of biting off his trencher-wood he slashed it with a blade the like of which Jing had never seen, made from some dark but shiny and very sharp substance.

"Sit here with my compeers," Twig muttered. "Eat fast. There may not be long to go. He's in a surly mood."

Thinking to make polite conversation, Jing said, "Has two lovely shes, this lord. Is of the children many to him credit?"

The scholar's colleagues, Bush, Hedge and so on—names doubtless adopted, in accordance with local custom, when they took service with the Count—froze in unison. Twig whispered forcefully, "Never speak of that where he might overhear! No matter how many women he takes, there is no outcome and never has been, except ... See the cripple?"

Previously overlooked, there sat a girl by herself, her expression glum. She leaned to one side as though she had been struck by an assassin's prong. Yet she bore a visible resemblance to the Count, and she was passably handsome by the standards of Ntah where the mere fact of her being a noble's daughter would have assured her of suitors. She was alone, though, as if she were an unmated or visiting male. Had he again misunderstood some local convention?

Twig was continuing between gobbles of food. "She's the reason I'm here—eat, eat for pity's sake because any moment he's going to order up the evening's entertainment which is bound to include you and over there"—with a nod towards a trio of emaciated persons whom Jing identified with a sinking feeling as sacerdotes—"are a bunch of charlatans who would dearly have liked to sink claws in you before I did except that I put it about I wasn't expecting you before the last boat of autumn in ten days' tune. Anyway, Rainbow—who is much brighter than you'd imagine just looking at her—is his sole offspring. Naturally what he wants is a cure for infertility and an assurance that his line won't die out. So our real work keeps getting interrupted while we invent another specious promise for him."

For someone afraid of being overheard, Twig was speaking remarkably freely. But Jing was confused. "You not try read his future from stars?" he hazarded. "You not think possible?"

"Oh, it may well be! But before we can work out what the sky is telling us, we must first understand what's going on up there. My view, you see, is that fire above and fire below are alike in essence, so that until we comprehend what fire can do we shan't know what it is doing, and in consequence—Oh-oh. He's stopped eating, which means the rest of us have to do the same. If you haven't had enough to keep you dreamfree I can smuggle something to your quarters later. Right now, though, you're apt to be what's served him next!"

In fact it didn't happen quite so quickly. With a spring like a stabber-claw pouncing out of jungle overgrowth, a girl draped in glitterweed erupted from shadow. She proved to be a juggler, and to the accompaniment of a shrill pipe made full use of the hall's height by tossing little flying creatures into the air and luring them back in graceful swooping curves.

"She came in on the first spring boat," Twig muttered, "and is going away tomorrow—considerably richer! Even though she didn't cure the Count's problem, he must have had a degree of pleasure from her company..."

Certainly the performance improved the Count's humor; when it was over he joined in the clacking of applause.

"We have a foreign guest among us!" he roared at last. "Let him make himself known!"

"Do exactly as I do!" Twig instructed. "First you—"

"No!" Jing said with unexpected resolve. "I make like in my country to my lord!"

And strode forward fully upright, not letting the least hint of pressure leak from his tubules. Arriving in front of the Count, he paid him the Ntahish compliment of overtopping him yet shielding his mandibles.

"I bring greeting from Ntah," he said in his best Forbish. "Too, I bring pearlseeds, finest of sort, each to grow ten score like self. Permit to give as signing gratitude he let share knowledge of scholars here!"

And extended what was in fact his best remaining seed.

For an instant the Count seemed afraid to touch it. Then one of his treasurers, who stood by, darted forward to examine it. He reported that it was indeed first-class.

Finally the Count condescended to take it into his own claw, and a murmur of surprise passed around the company. Jing realized he must have committed another breach of etiquette. But there was no help for that.

"You have no manners, fellow," the Count grunted. "Still, if your knowledge is as valuable as your pearlseed, you may consider yourself welcome. I'll talk with you when Twig has taught you how to address a nobleman!"

He hauled himself to his pads and lumbered off.

"Well, you got away with that," Twig murmured, arriving at Jing's side. "But you've pressurized a lot of enemies. Not one of them would dare to stand full height before the Count, and they claim to have authority from the Maker Himself!"

Indeed, the three sacerdotes he had earlier designated charlatans were glowering from the far side of the hall as though they would cheerfully have torn Jing mantle from torso.

III

"And here is where we study the stars," said Lady Rainbow.

It had been a long trek to the top of this peak, the northernmost of those girdling the round valley. Their path had followed the river which eventually created the channel used by boats from the south. It had not one source, but many, far underground or beyond the hills, and then it spread out to become a marsh from which issued bubbles of foul-smelling gas. Passage through a bed of sand cleansed it, and thereafter it was partitioned into many small channels to irrigate stands of fungi, useful trees, and pastures on which grazed meatimals and furnimals. Also it filled the castle fish-ponds, and even after such multiple exploitation it was warm enough to keep the channel ice-free save in the dead of winter. The whole area was a marvel and a mystery. It was even said that further north yet there were pools of liquid rock which bubbled like water, but Jing was not prepared to credit that until he saw it with his own eye.

Despite her deformity, Rainbow had set a punishing pace, as though trying to prove something to herself, and Twig had been left far behind on the rocky path. He was in a bad temper anyway, for he had hoped to show off his laboratory first, where he claimed he was making amazing transformations by the use of heat, but Rainbow had insisted on coming here before sunset, and Jing did want to visit the observatory above all else.

However, he was finding it a disappointment. It was a mere depression in the rock. Walbushes had been trained to make a circular windbreak, and their rhizomes formed crude steps enabling one to look over the top for near-horizon observations. A pumptree whose taproot reached down to a stream of hot water grew in the center where on bitter nights one might lean against it for warmth. A few lashed-together poles indicated important lines-of-sight. Apart from that—nothing.

At first Jing just wandered about, praising the splendid view here offered of Castle Thorn and the adjoining settlements. There were more than he had imagined: almost a score. But when Twig finally reached the top, panting, he could contain himself no longer.

"Where your instruments?" he asked in bewilderment.

"Oh, we bring them up as required," was the blank reply. "What do you do—keep them in a chest on the spot?"

Thinking of the timber orrery which had been his pride and joy, twice his own height and moved by a pithed water-worm whose mindless course was daily diverted by dams and sluices so as to keep the painted symbols of the sun, moon and planets in perfect concordance with heaven, Jing was about to say, "We don't bother with instruments small enough to carry!"

But it would have been unmannerly.

Sensing his disquiet, Twig seized on a probable explanation. "I know what you're tempted to say—with all that steam rising from our warm pools, how can anyone see the stars? You just wait until the winter wind from the north spills down this valley! It wipes away mist like a rainstorm washing out tracks in mud! Of course, sometimes it brings snow, but for four-score nights in any regular year we get the most brilliant sight of heaven anyone could wish for, and as for the aurorae...!"

Touching Rainbow familiarly, he added, "And you'll be here to watch it all, won't you?"

"You must forgive Twig," she said, instantly regal. "He has known me since childhood and often treats me as though I were still a youngling. But it's true I spend most of my time here during the winter. I have no greater purpose in life than to decipher the message of the stars. I want to know why I'm accursed!"

Embarrassed by her intensity, Jing glanced nervously at her escorting prongsman, without whom she was forbidden to walk abroad, and wished he could utter something reassuring about Twig's abilities. But the words would have rung hollow. He had pored over Jing's star-maps, cursing his failing sight which he blamed on excessive study of the sun— in which Jing sympathized with him, for his own eye was not as keen as it had been—and exclaimed at their detail, particularly because they showed an area of the southern sky which he had never seen. All he had to offer in exchange, though, were a few score parchments bearing scrappy notes about eclipses and planetary orbits, based on the assumption that the world was stationary, which had been superseded in Ntah ten-score years ago, and some uninspiring remarks about the New Star. It was clear that his real interest lay in what he could himself affect, in his laboratory, and his vaunted theory of the fire above was plausibly a scrap from a childhood dream. Jing was unimpressed.

He said eventually, "Lady, where I from is not believed curses anymore. We hold, as sky tend to fill more with star, so perfectness of life increase down here." And damned his clumsiness in this alien speech.

"That's all very well if you admit the heavens change," said Twig bluffly. "But we're beset with idiots who are so attached to their dreams they can go on claiming they don't, when a month of square meals would show them better!"

He meant the sacerdotes, who—as Jing had learned—had been sent to Castle Thorn unwillingly, in the hope of winning the Count back to their "true faith," and were growing desperate at their lack of success even among the peasants, because everyone in this valley was well enough nourished to tell dream from fact. One rumor had it that they were spreading blight on the trencher-plants, but surely no one could descend that far! Although some of the lords of Forb...

Disregarding Twig, Rainbow was addressing Jing again. "You say I can't be cursed?"

"Is not curse can come from brightness, only darkness. More exact, is working out pattern—I say right pattern, yes?—coming towards ideal, and new thing have different shape. You noble-born, you perhaps a sign of change in world."

"But if change is coming, nobody will prepare to meet it," Twig said, growing suddenly serious. "With the trunks of Forb and other ancient cities rotting around them, people shout ever louder that it can't be happening. They'd rather retreat from reality into the mental mire from which—one supposes—our ancestors must have emerged. You don't think Lady Rainbow is accursed. Well, I don't either, or if she is then it's a funny kind of curse, because I never met a girl with a sharper mind than hers! But most people want everything, including their children, to conform to the standards of the past."

"My father's like that," Rainbow sighed.

"He's a prime example," Twig agreed, careless of the listening prongsman. "He thinks always in terms of tomorrow copying today. But our world—I should say our continent—is constantly in flux; when it's not a drought it's a plague, when it's not a murrain it's a population shift ... Where you come from, Jing, how does your nation stay stable even though you admit the heavens themselves can change? I want to know the secret of that stability!"

"I want to know what twisted my father!" snapped Rainbow. "Bent outwardly I may be, but he must be deformed within!"

Aware of being caught up in events he had not bargained for, Jing thought to turn Rainbow a compliment. He said, "But is still possible to him descendants, not? Surprise to me lady is not match often with persons of quality, being intelligent and of famous family."

Later, Twig explained that to speak of a noblewoman being paired was something one did not do within hearing of the party concerned. For the time being he merely changed the subject with an over-loud interruption.

"Now come and see what's really interesting about the work we're doing!"

Yet, although she declined to accompany them to the laboratory, the lady herself seemed rather flattered than upset.

This time their path wound eastward to the place where the hot river broke out of shattered rocks. Alongside it a tunnel led into the core of a low hill, uttering an appalling stench. Yet the heat and humidity reminded Jing's weather-sense of home, and inside there were adequate glowplants and twining creepers to cling to when the going became treacherous. Sighing, he consented to enter.

When he was half choking in the foul air, they emerged into a cavern shaped like a vast frozen bubble, at whose center water gushed up literally boiling. Here Hedge, Bush and the rest were at work, or more exactly directing a group of ill-favored peasants to do their work for them.

They paused to greet their visitor, and Twig singled out one husky fellow who sank to half his normal height in the cringing northern fashion.

"This is Keepfire! Tell Master Jing what you think of this home of yours, Keepfire!"

"Oh, it's very good, very safe," the peasant declared. "Warm in the worst winter, and food always grows. Better here than over the hill, sir!"

Jing was prepared to accept that. Anything must be preferable to being turned loose to fend for oneself in the barren waste to the north, where no plants grew and there was a constant risk from icefaws and snowbelongs, which colonized the bodies of their prey to nourish their brood-mass. Twig had described the process in revolting detail.

Having surveyed the cavern and made little sense of what he saw, Jing demanded, "What exact you do here?"

"We're testing whatever we can lay claws on, first in hot water, then on rock to protect it from flame, then in flame itself. We make records of the results, and from them we hope to figure out what fire actually can do."

To Jing, fire was something viewed from far off, veiled in smoke and to be avoided, the flame was a conjurer's trick to amuse children on celebration days. More cynically than he had intended—but he was growing weary and dreams were invading his mind again—he said, "You are proving something it does?"

Stung, Twig reached up to a rocky ledge and produced a smooth heavy lump which shone red-brown.

"Seen anything like this before? Or this?"

Another strange object, more massive and yellower.

Realization dawned. "Ah, these are metals, yes? You find in water?" Sometimes in the streams which fed the lake of Ntah placer-nuggets turned up, softer than stone ought to be, which after repeated hammering showed similar coloration.

"Not at all! This is what we get when we burn certain plants and then reheat their ash. Don't you think some of the essence of fire must have remained in these lumps? Look how they gleam! But I should have asked—what do you already know about fire?"

"Is to us not well known. In dry land is danger for plants, homes, people. But in Ntah is air damp same like here. Is down in this cave possible flame?"

His doubt was plain. Twig snorted.

"I thought so! The more I hear, the more I become convinced we must be the only people in the world seriously investigating fire. Either they think it's blasphemous because it's reserved to the heavens, or they're as wrong as you about the way it works. Let a humble peasant show you better. Keepfire, make a flame for the visitor!"

Chuckling, the peasant rushed to a recess in the cavern wall. From it he produced articles which Jing's poor sight failed to make out in the dimness.

"Long before anyone came here from as far south as Forb," Twig said softly, "Keepfire's ancestors were priests of a cult which now has vanished—based on dreams, of course. But they found out some very practical techniques."

"What he do?"

"It's so simple you wouldn't believe it. I didn't when I first came here. He uses dry fungus-spores, and a calamar soaked in fish-oil, and two rocks. Not just ordinary rock, a kind that has some of the fire-essence in it. Watch!"

Something sparkled. A flame leapt up, taller than himself, and Jing jumped back in alarm. He risked tumbling into the hot pool; Twig caught him, uttering a sour laugh.

"Doesn't that impress you?"

"I guess so..." Jing was trembling. "But what to do with? Is not same fire and in—as in sky! Is under the ground!"

Twig said with authority, "The idea that fire belongs to the sky is false. Using it, we've made—not grown but made—things that were never in the world before."

"Did you make Count's blade?" Jing ventured, prepared to be impressed.

"Oh, no. That's a natural rock you find a lot of around here. But it too must have fire in its essence, or heat at any rate. It seems to be like this stuff." Twig reached to another ledge and brought down a clawful of smooth transparent objects shaped like half a raindrop, most bluish, some greenish, one or two clear. "The peasants' children use these for playthings. They hate me because I take away the best ones for more important use. On a fine day you can catch sunfire with them and set light to a dry calamar or a dead leaf. What better proof could there be of my opinions? Look, here's a particularly clear one!"

To Jing's touch the droplet was relatively cool, so he could not imagine how fire could be trapped within. All of a sudden, however, as he was inspecting it, he noticed something remarkable. At a certain distance he could see his claw through it, only enlarged.

"It make big!" he breathed.

"Oh, that too! But it's no use holding it up to the sky. Every youngling in the valley must have tried that, and me too, I confess. But it won't make the moon or stars any plainer, and as for looking at the sun—well!"

"I can have, please? Not to start fires. Is good for look my star-maps."

Twig started. He said in an altered voice, "Now, why didn't I think of that? But of course I never saw maps like yours before, with such fine detail ... Sure, take it. We keep finding them all the time. Now we'd best get back to the castle."

He padded away, exuding an aura of annoyance.

This was no astrologer: Jing was satisfied on that point. Maybe when it came to trying this or that in a fire Twig's record-keeping might be accurate, but given he could overlook such an obvious use for a magnifying drop it seemed unlikely. Anyhow, what value could his data nave? It was inconceivable that fire in heaven could be identical with fire underground!

So perhaps there were several kinds of fire? And surely there must be some way of enlarging the heavens if it could be done at close range...?

Jing sighed heavily. He had to make an immediate decision: whether to remain here in the hope that studying the stars uninterruptedly for longer than he had imagined possible would bring unexpected insights, or leave by the final autumn boat. But the continent was already in the grip of winter; he could scarcely reach home any sooner, if he left now, than if he stayed until spring. And Waw-Yint would certainly not forgive him for abandoning his mission. He was not one to be bought off with such petty marvels as a magnifying drop. True, he was old, and by now might well be dead—

Shocked at his own disloyalty, Jing firmly canceled such thoughts. No, he must remain, and if necessary next year carry on beyond the ocean, riding one of the half-legendary giant barqs of which they spoke in Yown and Forb ... if they were not compounded of dreams.

Besides, this magnifier ... It had seized his imagination, an ideal tool for astrologers hampered only by its present imperfection. He had been brought up to believe that perfection inhered in everything, even people; it needed only to be sought out.

Just before entering the castle again, Twig turned to him and said bluffly, "Put what I know about the world below together with what you know about the sky, and we might get somewhere one of these days, right? Shall we try?"

It was a formal invitation not just to collaborate but to make friends.

Jing felt obliged to treat it as such, despite his reservations concerning Twig's researches. They locked claws accordingly.

Later, Jing reflected it was as well they concluded their compact at that juncture, for the first person to meet them within the castle reported Drakh's death; the best of Twig's cleanlickers had failed to purify his wound. Grief at being shorn of his last Ntahish companion might have driven him to dreamness and made him reject Twig-friend because of Twig-physician. Yet no blame could attach save to those who had stabbed Drakh a month's journey ago.

When, in compliance with local custom, they consigned Drakh's remains to a pullulating pond surrounding a handsome blazetree, Twig spoke much about loneliness and isolation, and Jing was touched and grateful.

As though the funeral were a significant occasion, the Maker's Sling delivered a cast of long bright streaks across the zenith.

But that was apt to happen any night.

IV

Next day distraught peasants came crying that a snowbelong had killed a child from the furthest-outlying village, and the Count hauled himself out of his sitting-pit and set off to hunt it down with hoverers and canifangs. Twig predicted it might be several days before he returned, and Jing looked forward not only to improving his Forbish but also to cleansing his mind of the nostalgic dreams which since the death of Drakh threatened to overwhelm him.

Taking advantage of his absence, however, the sacerdotes promptly summoned Jing to their chapel, an enclosure within the north wall of the castle which they had been granted because the Count, despite being well fed, was sufficiently at the mercy of his dreams to half believe their dogma.

"You'll have to go, I'm afraid," sighed Twig.

"Here I thought had they no power. How they force me?"

"Hmm! It isn't quite like that. True, the Count's rule is absolute here, and the people, if they have a religion at all, adhere to superstitions even more absurd than the sacerdotes', though some of their knowledge, especially where fire is concerned ... Excuse me. The point is, the Count has opened up this place to trade with the south, and that means contact with southern believers. Most of the summer there are at least half a score of the faithful here, and the sacerdotes incite them to put pressure on the Count, who's growing senile. What I'm afraid of is that sooner or later he may conclude that they're right after all, and hoping to escape the curse he'll go whining to them for forgiveness, and you can guess what'll become of the rest of us then! At all events they're getting bolder, and if you don't obey their summons you could well find your food poisoned or a prong stuck in your back."

Jing would have dismissed the idea as ridiculous but for what had happened to Drakh. Sensing his dismay, Twig added, "If it's any comfort, though, you should bear in mind that it would be a far greater coup for them to convert you than kill you. They may be a nuisance but they're not likely to be a menace."

At least these sacerdotes were less determined to execute what they held to be the Maker's will than their counterparts at Forb. They greeted him politely as he entered the chapel, which was decorated with makeshift symbols: the Sling, of course, shiny with glitterweed; a pile of the seared rocks which were held to be what the Sling cast, but looked much like any other rock except for superficial melt-marks; some rather repulsive models of victims of the Maker's wrath, struck down from on high.

For a while there was ordinary conversation, about his homeland and his various travels. Jing answered as best he could, wishing he had asked Twig their names, for they had not offered them and direct inquiry might be rude. There were a chief, a middle and a junior; that would have to do.

Finally the chief broached the main subject. He said, "What god is worshiped in your land?"

"Most people not," Jing said. "Is some old and sick folk think of pleasing gods, but to rest of us is imaginary thing. We tell easily dream from fact, same as here."

"You don't believe in a creator at all?" the middle one demanded. "You don't think the world was created?"

"Is certain," Jing said. "But very long past. We think"—he groped for words—"world is made as path for us to go on as we choose. Important is to learn from sky whether we take right or wrong way. Creator is watch us, but not for punish, not for want offerings, just for see how done by us. When well done, more star come in sky. Perhaps in farthest future all sky is starry, and all here below walk in light all time."

He hated to give this bald account of the system Ntahish philosophers had evolved over many score-of-score years, but it was the best he could manage.

The junior, who was better-favored than his colleagues, spoke up eagerly. "But the New Star did light the whole of the night sky! For a while it could even be seen by day! Do you think—?"

"There is no New Star!" the chief snapped. "It's an illusion!"

Humbly the junior said, "Sir, I'm aware of that. But with respect it seems our visitor is not. I only wish to learn what explanation his people have—well, invented for it."

Gruffly, the chief granted permission for the question.

"We not have explanation," Jing admitted. "Never saw so much bright star appear in past, not at any rate to stay so long. In Ntah is no great change to explain it. Here why I am sent to ask in foreign lands."

"You actually imagine there have been other new stars?" asked the middle one. "Dreamstuff!"

"Can show you true. I bring copies of old sky-maps to make proof. Is also much difference in time of rise and set from old days. Will explain meaning of maps when want you!"

"Your star-maps," said the chief sacerdote coldly, "are of no interest to us. Any apparent change in the heavens must be due to the working of evil forces passing off dreams as reality. Bring your maps, yes, but so that we can burn them and save other people from your mad ideas!"

That was more than Jing could bear. Rising to his full height in the most disrespectful manner possible, he said, "Is your belief, anyone make use of fire is companion of evil, yes? You just propose that same! I say plain: I better tell dream from true than you! And anyway, is not place of you to order foreigner, guest of Count!"

The middle one scowled a warning, aware his chief had gone too far. After a moment the latter rose, glowering.

"The Count is not yet back! He is a reckless hunter and may well not come back at all! And if he doesn't, then we'll see about you!"

He stormed away.

Greatly distressed, the junior sacerdote escorted Jing to the exit, muttering apologies. And, as soon as they were out of hearing, he did the most amazing thing. Leaning confidentially close, he whispered, "Sir, I would like to see your sky-maps! Since coming here, I no longer think the heavens never change! I think new stars signal the birth of righteous persons, and the most righteous of all must now be among us!" Before Jing could recover from his startlement, he was gone.

At first Jing was inclined to hasten straight back to Twig, but a moment's reflection changed his mind. Even in peaceful Ntah there were such things as court intrigues, and while in his profession he had been largely insulated from them, he was well aware of the need to protect himself. Given the Count's absence, might his daughter offer a degree of help, or at least advice? From a passing prongsman he inquired the way to her ladyship's quarters.

They proved to be in a large and comfortable bower on the west side of the castle, where she sat poring over a table of Ntahish mathematical symbols he had prepared for her. He was relieved to find she did not resent interruption; on the contrary, she declared herself delighted, and sent her maids to bring refreshments.

"I'm so pleased you're here!" she exclaimed, speaking as directly as a man. "Here at Castle Thorn, I mean. I'd never say so in Twig's hearing, but I long ago learned all he had to teach me about the sky, and it didn't even include the idea that the sun stands still while we move around it. It makes everything so much simpler when you look at things that way, doesn't it? I look forward to having you as my constant companion at the observatory this winter."

"To me will much pleasure," Jing affirmed. "But if to explain correct meaning I want say, must I very more Forbish learn."

"I'm sure you'll learn quickly, and if you have problems, turn to me. I have little enough to occupy me," she added in a bitter tone.

Thus emboldened, Jing said, "Is of problem I come now. See you..." And he summed up his encounter with the sacerdotes.

"You're right to beware of them!" Rainbow asserted. "How can I but hate them for claiming that my birth was the sign of a curse on my father? For him I have small love either, since he sent my mother away, but at least he had the kindness to bring me with him when he left Forb instead of abandoning or even killing me, and he provided for my education by offering Twig a refuge here. Without him I think I would have lost myself in dreamness. If only he hadn't more or less quit studying the sky when his eye began to fail ... Still, he had only himself to blame for looking directly at the sun. He told you, did he, how he saw dark markings on it?"

"I hear of it in Forb, but he not say himself."

"Do you think it's credible? Sometimes when there's thin gray cloud, so the sun doesn't hurt your eye, I've imagined that I too ... But what do you think? Is it possible for dark to appear out of bright, as bright may out of dark?"

"In not in the knowledge of my people. Where I lived, is either clear day-sky or thick rain-cloud. Was to me new, see sort of thin cloud you mention."

"Is that so?" She leaned forward, fascinated. "I should ask you about your homeland, shouldn't I, rather than about stars and numbers all the time? Have you been away long? Do you miss it very much? Is it a place of marvels? I suspect it must be, particularly compared to this lonely backwater ... But quickly, before my maids return: I'll assign you one of my own prongsmen to replace Drakh. I'll say it's because you need someone to practice Forbish with. I'll give you Sturdy. With him at your side you need fear nothing from the sacerdotes."

"Am not sure all to be feared," Jing muttered, and recounted the odd behavior of the junior sacerdote.

"Interesting! That must be Shine you're talking about. I realized long ago he was too sensible to deprive himself of the good fare we can offer, but I'd no idea he'd become so independent-minded. Cultivate him! It could serve us well to have a split in the enemy's ranks."

Jing noted in passing how swiftly she had begun to say "us."

"Tonight in hall sit with me," Rainbow continued. "I'll feed you from my own trencher-stump. That is, unless you're afraid of offending my father's wives. But they have no power; he takes and dismisses them according to his mood, and until one of them buds I remain his sole heir. Now here come my attendants. Let's change the subject. You were telling me about your homeland. The very weather is different there, I think you said. In what way?"

With infinite gratitude Jing slipped into memory, purging the risk of dangerous dreams. He described the subtropical climate of Ntah, and then progressed to a general account of the Lake and its environs—the creeperbridges stranding out from island to island; the Lord's palace at the center, a huge tree sixty-score years old, whose sides were draped with immense waxy blossoms that scented the air for miles around; the western cataract where a broad river plunged over a cliff and kept the Lake from growing stagnant; the delectable flesh of the nut called hoblaq, enclosed in a shell too hard for anyone to break, which people gathered on the hillside and pitched into the river so that the falls would do the work for them and send the shattered kernels drifting across the water V

The slopes and branchways of the castle were eerie in the long darkness, although the glowplants drew enough warmth from underground to provide faint luminance right through until spring. They were, Jing thought, like a model of his mind, a pattern matching himself alone as the sky matched the entire world. Some areas were darkly red, like those deep-lying mental strata concerned with fundamental processes such as digestion, where one might venture only in emergency and at the cost of immense concentration; others were pinker and brighter, like the levels where one might issue commands to oneself about sitting or standing, walking or climbing—or fighting; others again tended to be bluish, like the dreams harking back to childhood incomprehension of the world which could so easily overpower a person when weary, sick, frightened, grief-stricken or undernourished, and which sacerdotes and other fools deliberately cultivated because they had never learned to prize dreams less than memory; yet other levels were greenish as memory was; more still gleamed clear yellow like imagination; and just a few, including the great hall itself, shone with the white brightness of reality.

Contrary to what the chief sacerdote had hoped, the Count had a for everybody to enjoy; the game animals large and small which haunted the copses, the shallows and the water-meadows; the venomous insects and noxious berries which were obliging enough to advertise themselves by distinctive coloring, so even children might avoid them; and of course his prized observatory, with its orrery and its transits and its levels and its gnomons and its great trumpet-shaped viewing-funnel of dried pliobark, which blanked off all light from below and permitted the eye to adjust completely to its task of registering the stars .

"And we think we're advanced!" Rainbow cried. "How could you have brought yourself to leave such a place?"

It was a question Jing was to ask himself countless times during the next few months, particularly after the last boat of autumn had come and gone and the sun had set for the last time in six-score days. successful hunt, and his prongsmen dragged back enough snowbelong meat to garnish a score of winter meals. But he had fallen into a crevasse and ruptured some of his interior tubules. More bloated than ever, he summoned Jing to attend him under the misapprehension that all foreigners were skilled physicians. Jing, having seen a similar case when an elderly man slipped on the approach to the cataract at Ntah, offered suggestions which appeared to give relief from pain, if nothing more. Impressed, the Count made a vague attempt to engage in debate concerning the patterns in the sky, but after that he seemed to lose interest.

Much the same could be said of Twig. Once he realized that Jing's star-maps were not only in an alien script but based on a sun-centered convention, he gave up. It was not because he shared the sacerdotes' conviction that the sun was only the Maker's Eye and therefore could not be the focus around which the planets revolved; enough observations had been amassed here in the north to indicate to him how far superior the Ntahish system was. No, the problem arose from a wholly unexpected source: Keepfire.

As the story came back to Jing, the elderly peasant whose ancestors had been a priesthood was angered by the fact that certain substances resisted change in his hottest flames. He therefore set about interrogating the oldest of his kinfolk in search of ways to make them even hotter. Siting a fire at the spot where a crack in the rock, leading to the outside, was aligned with the prevailing wind made the fuel blaze up violently. Winds, though, were unpredictable; how to cause an artificial one? Well, when a barq's bladder burst ... Suppose one made a giant bladder out of hide? But that wasn't the answer by itself. It needed to be filled, and refilled, and refilled, and ... How about tethered hoverers?

The problem engaged Twig's total attention. Sighing, Jing left him to get on with it, feeling lonelier than ever.

In absolute contrast, Rainbow was desperate for the information contained in Jing's maps. The regular winter wind had set in, but actual star-study was out of the question; there were constant snow-flurries, and whenever the gale died down the water was warm enough to generate fog. Jing, though, was in no mood to complain. He was taking a long while to adjust to the loss of his last Ntahish companion, and until he had rid his mind of intrusive dreams he was content to tutor Rainbow. He was greatly impressed by her quick wits. She had realized at once how much simpler a sun-centered system made it to keep track of the outer planets, and the inner one which was so rarely visible. Moreover, when she ran across a technical term in Ntahish for which she knew no equivalent, she simply adopted it. Within a few days she was using words nobody else at Castle Thorn would have understood.

Except one...

It astonished Jing when the young sacerdote Shine lived up to his promise and shyly came to beg a sight of the star-maps. Instantly fascinated, he set about matching the names they bore with their Forbish equivalents. Soon his colleagues were openly quarreling with him. One evening only the authority of the Count prevented a fight breaking out in the hall.

Quite without intention, Jing thereupon found himself the center of interest throughout the castle. He could go nowhere without some wench accosting him to demand a favorable horoscope for her family, or a prongsman wanting to be told he would be promoted chief-of-guard over his rivals, or peasants seeking a cure for trencher-plant blight— though luckily the latter had been less virulent of late.

As soon as the air cleared, therefore, he and Rainbow went to the observatory as often as possible. All Twig's extravagant claims proved justified. The stars shone down sharp as stabberclaws, from a background so nearly black Jing almost could not believe it. Even the square surrounding the New Star was barely a contrast to the rest. As for the Bridge of Heaven, it gleamed like a treasury of pearlseeds.

A faint suspicion trembled on the edge of his awareness. But it refused to come clear as he strove with chill-stiff claws to prepare for the portion of the sky not seen from Ntah maps and tables as exact as those he had brought from home. Often dreams threatened to engulf his consciousness, and then he had to break off and embrace the warm trunk of the pumptree until he regained his self-possession.

It was a marvelous juncture for observation, though. Time had brought all five outer planets into the same quadrant—an event which might or might not have significance. A year ago he would have insisted that it must; now he was growing skeptical. But there was reddish Swiftyouth, currently in a retrograde phase of the kind which had led Ntahish astrologers to center their system on the sun; there was Steadyman, almost white, lagging behind; there was Stolidchurl, somewhat yellower; there were Stumpalong and Sluggard, both faintly green, the latter markedly less bright...

Why were there moving bodies in the sky, and of such different sizes? And why were they so outnumbered by the stars? Shine was eager to explain the teaching he had been brought up to: that each corresponded with a region of the world, and moved faster or slower according to whether the people of that region obeyed the Maker's will. One day they would all rise together at the same time as the sun rose in eclipse, and— Patiently Jing pointed out the fallacies in his argument. Clacking his mandibles, he went away to think the matter through. Apparently it was news to him that a solar eclipse was not simultaneously observed everywhere, a fact one might account for only by invoking distances beside which Jing's journey from Ntah to Castle Thorn was like a single step. It hurt the mind to think in such terms, as Rainbow wryly put it when he showed her how to calculate the circumference of the world by comparing star-ascensions at places on the same meridian but a known distance apart. He found the remark amusing; it was the first thing that had made him laugh in a long while.

Plants which swelled at noon and shrank at midnight were used in Ntah to keep track of time if the sky was clouded over and the weather-sense dulled. Whenever it snowed, Jing occupied himself by hunting the castle for anything which might exhibit similar behavior. The effect the long night was having on his own weather-sense was disquieting; without sunlight to prompt him back to rationality, he found dreams creeping up on him unawares when he was neither hungry, tired nor upset.

He was engaged in this so-far vain quest when he was hailed by a familiar voice. Turning, he saw Twig, filthy from pads to mandibles with blackish smears.

"There you are! I was surprised not to find you in Rainbow's quarters—they tell me you two have grown very close lately!"

For an instant Jing was minded to take offense. But Twig knew nothing of his being compelled to celibacy so long as Waw-Yint lived. And lately he had felt pangs of regret at not having left offspring behind in Ntah. Rainbow and Shine were about half his age; talking to them, he had realized how much happier he would have been had he passed on his knowledge to a son and daughter before setting forth on his travels...

Before he could reply, however, Twig had charged on, plainly bursting to impart information. "Take a look at this!" he exclaimed, proffering something in his left claw. Jing complied, hoping it was not something as irrelevant as Twig's last "great discovery": a new kind of metal, grayish and cold, which broke when it was dropped. This one, however, he thought he recognized.

"Ah! You found another magnifying drop. It's especially clear and fine, I must say."

"Not found," Twig announced solemnly. "Made."

"How? Out of what?"

"Sand, would you believe? Yes, the same sand you find beside the hot marsh! Keepfire's flames are getting better and hotter—oh, I know people are complaining about the smell, but that's a small price to pay!—and this time he's excelled himself! And there's more. Look at this!"

He produced what he had in his other claw. It was of similar material, equally clear, but twice the size.

"Hold them up together—no, I don't mean together. I mean—Oh, like this!" Twig laid claws on Jing in a way the latter would never normally have tolerated, but it was certainly quicker than explaining. "Now look at something through both of them, and move them apart or together until you see it clearly. Got it?"

Jing grew instantly calm. There presented to his eye was an image of Twig, albeit upside-down ... but larger, and amazingly sharp except around the edges.

Very slowly, he lowered and examined the two pieces of glass. They were not, as he had first assumed, in the regular half-droplet shape; they were like two of the natural kind pressed together, but considerably flatter.

"You made these?" he said slowly.

"Yes, yes!" And then, with a tinge of embarrassment: "Well—Keepfire made them, under Bush's supervision. All I was hoping for was better magnifying drops. I never expected that when you put one behind another you'd get even more enlargement the wrong way up! At first I thought I was in a dream, you know? But you agree it works?"

"Yes—yes, no doubt of it!"

"Right! Let's go and look at stars!"

"It's snowing. That's why I'm here."

"Oh, is it? Oh. Then—"

"Then we'll just have to force ourselves to wait until it blows over. But I promise you, friend Twig, I'm as anxious as you are to inspect the heavens with such amazing aids!"

The moment the weather cleared, he and Twig and Rainbow and Shine—for the secret was so explosive, it had to be shared—along with Sturdy, who hated coming here in the cold and dark, plodded to the observatory, forcing themselves not to make a premature test. Then it turned out that the lenses had misted over, and they had to find something dry enough to wipe them with, and...

"Jing first," Twig said. "You're the most knowledgeable."

"But surely you as the discoverer—"

"The credit is more Keepfire's than mine! Besides"—in a near-whisper—"my eye's not keen enough."

"My lady—" Jing began. Rainbow snapped at him.

"Do as Twig says!"

"Very well. Where shall I look first?" He was shaking, not from cold, but because excitement threatened to release wild dreams to haunt his mind like savage canifangs.

"At Steadyman," she said, pointing where the gaps in the cloud were largest. "If there's a reason why some stars are wanderers, it may be they are specially close to us. You've taught me that our own world whirls in space. Maybe that's another world like ours."

It was a good, bright and altogether ideal target. Jing leaned on the walbush stems, which were frozen stiff enough to support him. It took a while to find the proper position for the lenses, and then it took longer still for his sight to adjust to the low light-level—particularly since there were curious faint colored halos everywhere except at the dead center of the field. Eventually, however, he worked out all the variables, so he had a clear view. At last he said:

"Whether it's a world like ours, I cannot say. But I do see two stars where I never saw any before."

"Incredible!" breathed Twig, and Jing let go pressure from his limbs with a painful gasp and passed the lenses on. In a while:

"Oh! Oh, yes! But very indistinct! Rainbow, what do you see?"

She disposed herself carefully, leaning all her weight on her crippled side. Having gazed longer than either of them, she said, "Two stars beside the planet. Sharp and clear."

Turning, she sought Stolidchurl, and did the same, and exclaimed. "Not two more stars, but three! At least I think three ... I—Shine, you look. Your sight is very keen, I know."

His mandibles practically chattering with excitement, the young sacerdote took his turn. "Three!" he reported. "And—and I see a disc! I always thought the planets were just points, like the stars! But I still see them as points! And what do you make of the colored blurs these lenses show?"

"Could it be that we're seeing a very faint aurora?" Rainbow ventured. "Jing, what do you think?"

Jing ignored her, his mind racing. If one put such lenses in a viewing funnel—no, not a funnel, better a tube—of pliobark, or whatever was to be had here in the north, and made provision for adjustment to suit different observers...

He said soberly, "Twig, this is a very great invention." "I know, I know!" Twig clapped his claws in delight. "When I turn it on the sun, come spring—"

"You'll burn out what's left of your sight," Rainbow interjected flatly.

"Making the sun as much brighter as the stars now appear will blind you.

But there must be a way. Apply your genius to the problem, while the rest of us get on with finding unknown stars. Perhaps they hold the key to what's amiss with cripples like me."

VI

For the rest of the winter all four of them were embarked on a fabulous voyage of discovery. The world receded until they could wander through it unheeding, like a thin mist; all that mattered was their study of the sky. Shine abandoned his duties altogether, and his superiors threatened to kill him, but he put himself under Rainbow's protection and with Sturdy and her other prongsmen ready to spring to his aid they dared not touch him.

Growing frightened because his ruptures would not heal, the Count occasionally sent for them to demand how their work was progressing, but during their eager attempts at explanation his mind tended to stray, and he invariably wound up by raging at them because they cared more for star-lore than medicine. Nobody else in the castle—not even Twig's aides like Hedge and Bush, who refused to venture forth when the wind was bitter enough to build frost-rime on one's mandibles—seemed to care that a revelation was in the making. Twig said it was because the cold weather had sent their minds into hibernation, like the dirq and fosq which were so abundant in the summer and vanished into burrows in the fall.

There was one signal exception: the peasant Keepfire.

Throughout his life he had scarcely seen the stars. It was a tradition in his family that at winter sunset they should retreat to their cavern until spring reawoke the land. Twig, however, was sure it could not always have been so, and because he was so excited by what the lenses were revealing he patiently taught Keepfire how to store warm air under his mantle and persuaded him to the observatory at a time when the air was so clear the brilliance of the heavens was almost hurtful.

Such was Keepfire's amazement on learning that the glass he had melted from sand could show sparks of light where to the naked eye was only blackness, he returned home full of enthusiasm to improve on what he had already done. It being impossible to find fuel for new and hotter fires at this season—and hard enough at any time—he set about collecting every scrap of glass he could, whether natural or resulting from their experiments. For hours on end he sat comparing them, wondering how each differed from the rest. At last, in what the jubilant Twig termed a fit of genius, he thought of a way to shape the ones which were nearly good until they outdid those which were excellent.

Using the skin of a fish which was sown with tiny rough crystalline points, hunted by people but scarcely preyed on in the wild because swallowing it tail-first as it fled was apt to rasp the predator's gullet, he contrived to grind a poor lens into a good one, at least so far as form was concerned. But then it was seamed with fine scratches. How to eliminate them? There was no means other than rubbing on something softer than the glass, until the glass itself shed enough spicules to complete the task. This he set himself to do.

Nightless days leaked away, and Jing and his companions almost forgot about Keepfire, because every time they went to the observatory some new miracle presented itself.

At first Jing had thought it enough that, in the vicinity of the bright outer planets, there should suddenly appear new starlets which—as time passed—clearly proved to be satellites of what Shine had been the first to recognize as actual discs. But then they looked at the Bridge of Heaven, otherwise the Sling, and save at its midline it was no longer a band of uniform light; it was patently a dense mass of individual stars.

And there were so many stars! Even when the lenses were directed towards the dark square surrounding the New Star, at least a quarter-score (Shine claimed eight) other points of light appeared. At the zenith, near the horizon, it made no odds: wherever they looked, what had always been lightless zones turned out to be dotted with tiny glowing specks.

The New Star itself resolutely refused to give up any secrets. Even Shine's keen vision, which far surpassed the others', failed to reveal more than a bright spot with a pale blur around it, a cloud lighted as a fire might light its smoke from underneath. Was it a fragment of the Maker's Mantle, the aurora which at unpredictable intervals draped the sky in rich and somber colors? In Jing's view that was unlikely. Before coming to Castle Thorn he had only heard of aurorae. Now, having witnessed several, he was satisfied they must partake more of the nature of clouds than of stars, for they affected the weather-sense, as stars did not; moreover they did not necessarily move in the same direction as the rest of the sky. Were they then looking down on starfire from above? The image came naturally to folk whose ancestors had been the top-dwelling predators, but by the same token "up" and "down" meant one thing to them: towards or away from the ground underpad.

Jing and Rainbow debated long about the matter as soon as they realized that the little stars shuttling back and forth beside the planets must in fact be revolving around them, moon-fashion. By that stage Jing's prized star-charts were little more than memoranda; he already knew there was a lifetime's work in filling the gaps the unaided eye had left. The perspectives opened up to him were terrifying. Because if there were any number of different up-and-downs, then not only must the planets be worlds like the world, with their own—plural!—moons, but the sun, whose planets circled it like moons, might be circling something greater yet, and ... and ... It was dizzying to contemplate!

At least the moon lent them clues. Observations at the full showed that the sparkles visible on the dark part of its disc were only a fraction of what was actually going on. Flash after brilliant flash came and went seemingly at random, lacking even the momentary trace which followed a meteor. And here again Keepfire proved to possess unexpected insight. Shown the moon through his original lenses, he said at once, "It's like when I make a fire!"

And it was. By this time they had all watched his trick of striking rocks together and catching a spark on a tuft of shredded calamar.

Striking...

Jing felt he was being not so much struck as battered. It had been hard enough to accept the distances he had been taught about in childhood, necessary to let Sunbride race around the sun, the world stride around it, and the outer planets follow at their own respective speeds. What to make of a cosmos in which scores-of-scores-of-scores-of-scores (but it was pointless to try and count the stars in the Sling) of not just suns but their accompanying planets must be allowed for? If the sacerdotes were right in claiming that their sacred stones had fallen from heaven, and they were so tiny, could those brilliant lights above also be minute? Shine suggested as much, for he desperately wanted not to forsake all his former beliefs; in particular he clung to the notion that the New Star must indicate some great event in the world below. During a late snowstorm, however, Jing set him to making calculations based on the new observations, couched in the Ntahish symbols which were wieldier than what obtained in the north, and the results overwhelmed the poor exsacerdote, even though he had been properly fed for moonlongs past and learned to separate dream from fantasy as never before in his young life. They demonstrated beyond doubt that in order to leave room for planetary motions the lights in the sky must be not only far off but enormous. Did not a lantern fade to imperceptibility, no matter how skillfully you bred your gleamers, almost before its bearer was out of hearing? And when one added in an extra fact which Shine himself had drawn to their attention—that Swiftyouth sometimes appeared out of round, as though attempting phases like the moon's—there was precisely one explanation which fitted the evidence. The universe must be full of suns, and therefore presumably of planets too faint and far away for even their precious lenses to reveal.

A cosmic hierarchy of fire evolved in Jing's imagination: from the Sling compound of giant stars down to the briefest spark made by clashing rocks. Something pervaded all of them, something luminous, hurtful, transient, imponderable, yet capable of being fixed and leaving traces. Perhaps it penetrated everything! Was it the same force which made treetrunks strong enough to lift gigantic boulders, the same which brought forth blossoms, fruit and nuts? It might be, surely, for fire shone brightly and so did glowplants and glitterweed although they were cold to the touch and in color much like Stumpalong or Sluggard. So was there a connection? Suppose it was a matter of speed; suppose the slowness of plant-growth, and of the outer planets, meant cool, and the rapidity of flame meant hot: what did that imply about the stars? Remaining visibly the same for countless scores of years, must they not also be cool? Yet did not some of them now and then flare up? What about the bright streaks that nightly laced the firmament—must they not be cool, because manifestly the air was warm only when the sun had long shone on it? Yet Shine declared that those who had come on one of the Maker's sling-stones immediately after it landed invariably stated that it was too hot to touch, and indeed the surrounding area was often charred! What fantastic link was there between light and heat?

Vainly Jing sought to convey his thinking to his companions. He was as fluent now in spoken Forbish as Rainbow in the use of Ntahish numbers. She, though, had not yet escaped her original obsession; she had only come around to the view that it was pointless to try and read from the heavens the true reason for her deformity, because if there were so many invisible stars there might be one for everybody, and you could waste a lifetime seeking out your own. Before leaving home, or even as recently as the first time he looked at the sky through lenses, Jing might have considered such an argument valid; since getting over Drakh's death, however, he had experienced preternatural clarity of thought, and ideas which for half his life he had treated as rational had been consigned to memory, reclassified as imaginary or as dreamstuff. Perhaps this was due to the plain but nourishing diet he was eating; perhaps it had something to do with the monotonous environment of the long night, when he was free from the cyclic shock of sunrise and sunset; it didn't matter. What counted was that he could now clearly envisage other worlds. What a plethora of individuals might not inhabit all those planets, seen and unseen! What marvels might he yonder in the dark, more astonishing to him than Ntah to those who knew only Castle Thorn!

And what daunting celestial oceans of knowledge remained to be traversed, when by happenstance a humble peasant could open people's eyes to the miracles inherent in plain sand!

"We'll learn more of the answers," Twig kept promising in what he intended as a tone of comfort, "when the sun rises again. Darkness makes one's mind dull ... as the saying goes!"

Yet Jing's was not, nor Shine's. Could this be due to their constant intake of starfire? Could the mind as well be driven by the mysterious force? Was that why Keepfire, shut away in his foul-smelling cavern, believing in nothing and nobody save his traditional lore, was able to choose and pursue a course of action when Jing's mind was foggy with whirling symbols? Hedge and Bush became angrier and angrier with him, and subsided into sulky grumbling, so that no more new results emerged from the laboratory. Yet Keepfire worried on, and polished and pondered and talked to himself and polished some more, and...

And on that spring day when the sun's disc cleared the horizon entire for the first tune since fall, he came in triumph to Twig and Jing and Rainbow, and unfolded a scrap of the softest icefaw-hide, and revealed a pair of lenses of such impeccable shape that all the results of nature, or of early pourings, faded into insignificance.

Proudly he said, "Do I not bring the gift you wanted most? So I'll ask for what I want. You have shown me stars. They are little fires like the ones I understand. Now I want to see the biggest fire. Show me the sun!"

"But—" Rainbow began, and clipped off the words. Mutely she appealed to her companions, who could envisage as well as she the effect of looking at the sun through nearly perfect lenses.

Twig, however, was oblivious. He breathed, "To see the sun once with these would be enough to sacrifice my sight for!"

"Oh, shut up!" Jing roared. They shrank back as he erupted to his full height, every muscle and tubule in his body at maximum tension. "You're talking like a senile fool, and I speak to you as a sworn friend! Don't you think your eyesight will be useful tomorrow, too? What we need is a way to look at the sun without going blind!" He rounded on Keepfire. "Would you give up all vision for one fleeting glimpse of the sun? You'd rather see it over and over, wouldn't you?"

Alarmed, Keepfire signaled vigorous agreement.

"Very well, then!" Jing relaxed into a more courteous posture, but still tenser than his usual stance among friends. "What do we know of which makes a scene darker without blurring detail? In Ntah old folk some-tunes protected their sight on a sunny day"—he used the past tense unconsciously, and later thought of it as a premonition—"by using thin gray shells. But those deformed the image. Well?"

There was a long pause. At last Rainbow said, "You find membranes inside furnimals that are no good for parchment because you can see through to the other side."

Shine clacked his claws. "Yes! And stretching them can make them thinner still, yet they diminish light!"

"They make everything yellower!" Twig objected, and at once caught himself. "Ah, but the thinner, the clearer! So if we put several one behind another, and take away each in turn until the eye hurts ... Jing, I'm pleased to be your friend! Once again you see to the core of the matter when I spring to premature conclusions."

"If you want to honor someone, honor Keepfire," Jing said, and reached a decision not foreshadowed by intention. Taking the new beautiful lenses one in either claw, he shrank from his overweening posture to the lowest he could contrive without pain, and remained there while he uttered unpremeditated words.

"You know and I know, without putting it to the test, that these will reveal to us yet more amazing private knowledge. It should not be private; it would not be private, had anybody else within this castle shared our interest. But it is so, and must not remain so. Already we have learned so much, I want to share our findings with Ntah. The dullwits of Forb and every other city I traversed to come here ought to have their eyes opened—no? Even if like your fellow sacerdotes, Shine, they decline to take advantage, do they not deserve to have this knowledge pointed out to them?"

Shine shouted, "Yes—yes!"

Thus encouraged, Jing yielded to a half-guilty, half-ecstatic temptation and let his mind be taken over by the dream-level Imagination was not enough; it was handicapped by rational considerations like distance, delay, expenditure of effort, the obstinacy of other people. But already their new discoveries had made it plain that everyday knowledge was inadequate to analyze the outcome. For once his dream faculty might be wiser than his sober and reflective consciousness.

Suddenly his head was roaring-loud with revelations, as though he had tapped the sap-run of time. He marveled at what he heard himself say— or rather declaim.

"Oh-hya-na-ut thra-t-ywat insk-y-trt ah-bng-llytr-heethwa ibyong hr-ph-tnwef-r heesh-llytr-kwu-qtr-annibyong—ah, but I tackle poorly this speech of foreigners and wish I could say what is needful in the speech of the folk I grew up among! But I am far away and lonely beyond bearing so now my community is these who welcome me as friends and I speak to them and to the world because I overflow with knowledge born of fire! I have been set alight like dry crops on a distant hill and the scent of smoke from what I know must carry on the wind and warn the world of what's in store when heaven's fire descends to burn the densest wettest jungle and boil the Lake of Ntah! Vast fires surpassing number or belief loom yonder in the dark and we are cast away upon a fragile barq, this little world, and more and more fires loom and every night the dark is pierced with streaks of fire and what it is we do not know but we must master it or it will utterly consume us! We must pledge ourselves to spare the world the doom of ignorance, not keeping any knowledge private that we've found, but spreading it about to last beyond our lifetimes! You three and I must make a vow together, and in token of it take half another's name. The half is fire! It leaves a crust of duty ash but in another season it may turn to life anew and so our world must do although the prong of heaven strike us down! Take the vow, I beg you, I beseech you, and let not our secret knowledge vanish from the minds of those who on this lost and drifting orb hope to make something greater than themselves!"

He was almost screaming with the fury of his visions, for the countless stars were crashing together in a colossal mass of flame, and the world itself was ripe to be their fuel.

Fuel—?

Abruptly he was back to normal consciousness, and wanted to say something quiet and ordinary, though perfused with unexpected insight, but he could not, for Shine was clutching his claw and crying at the top of his voice.

"I know now what the New Star signified! One is come among us who has wisdom we have never guessed! I'll take the extra name and vow my service!"

"I too!" Old Twig was lowering himself, though his agony was plain. "You have united fire above and fire below and we must tell the world your teaching!"

Last, Rainbow, awkwardly, with her lopsided gait, drew close and said, "I vow the same. For what it's worth I'll bind my followers as well."

There was a pause. She looked at him uncertainly and said at long last, "Jing...?"

The tempest of impressions was fading from his mind. He rose, a little shyly, as though embarrassed. She said again, "Jing!" And continued: "What did you see? What did you see?"

But it was useless to try and describe everything that had so briefly stormed into awareness. He said eventually, "If stars are fire, then new stars happen when fresh fuel is fed to them. What fuel is there, barring worlds like ours? If we would rather not be fuel for a star, there's no one who can save us but ourselves ... I've dreamed. It's made me weary. I must rest."

VII

That evening Rainbow sent for Keepfire to share food publicly with them and cement their compact, which the peasant did nervously yet with obvious glee. This act made Shine a formal enemy of the other sacerdotes; it was, however, scarcely necessary, since he had long disdained the asceticism they relied on to make their dreams vivid. Afterwards Jing found his companions hanging on his every word as though he were indeed the ultimately righteous person harbingered by the New Star. He did his best to dissuade them, but the force of his vision had profoundly affected them, and it was useless. He resigned himself to being adulated. When they pressed him for some new revelation, all he was able to say was what they must already have known: "It will be spring tomorrow."

Further revelations from the sky, though, were delayed. Warm air from the south, drawn in by the constant thermals rising above the valley, met the still-frozen ground beyond the mountains, and fog and cloud veiled the sun. The ice which had temporarily blocked the access channel began to fracture with noises like a gigant snapping trees, and Jing was moderately content to occupy himself by preparing a detailed report of their discoveries for the doctor in Forb, which he planned to send south by the first barq of spring.

It arrived, and like the one which had brought him and Drakh, it carried a sick passenger.

Leaving Rainbow to polish his final draft, Jing went to the wharf to see the barq come in. He was unprepared to hear a voice hail him in Ntahish.

"It is the Honorable Jing? Here am I, Ah-ni Qat!"

Supported by two youthful aides, a boy and a girl, a stooped yet familiar figure limped ashore. Jing said disbelievingly, "The son of my dear friend the Vizier?"

For he remembered Qat as a sprightly youth, and this personage looked so old and moved so slowly ... and his skin was patched with ugly scars.

"Indeed, indeed! All whiter I've struggled across this snowbound continent because at Forb I heard rumors concerning your whereabouts. I'd not have had the endurance to continue but that my father laid on me the duty of seeking you out and telling you: Ntah is no more!"

For an instant Jing stood frozen. Then he said uncertainly, "Young friend, you're sick. You're ruled by dreams."

"Would that I were," Qat whispered. "After your departure plague ran wild among us. Never were such horrors witnessed by a living eye! People died where they stood, their bodies fell into the lake and river until the water grew so foul the very fish were poisoned. Those who survived lost their reason and fled under the lash of horrid dreams. Most went south. I doubt they escaped like me and my companions. Our northern route must have saved us. It seems the plague loves heat."

"Your father—" Jing began.

"Died among the first. So did Lord Waw-Yint. There is no use in speaking of his heir. Ntah is a land of rotting carcasses, and all who used to live there have run away."

Qat's girl companion uttered a groan of misery. Jing said slowly, "We must find you quarters. The Count has treated me kindly, as has his daughter. You will be made welcome."

Surrounded by the high-piled parchments on which he was recording their discoveries, Jing sat blindly staring at the overcast sky. His mind was fuller of despair than ever in his life before; he wanted to renounce consciousness and retreat to dreams, where Ntah would last for all eternity and its glory never fade.

Behind him creepers rustled. A soft familiar voice said, "Is it true about your homeland?"

He did not turn. "Yes, Lady Rainbow. If Qat says so, he speaks the truth. I no longer have a home."

"You have made one here," she said. "By your kindness to me from the beginning, when first you told me I was not after all accursed; when you said you were surprised I had not found mates in spite of my misshapenness; when you opened my sight to a heaven full of so many stars it's absurd for any one of us petty beings to count on reading his or her fate up yonder—Oh, Jing!" Spreading her mantle, she embraced him as he made to rise. "You have caused me to love you, poor twisted creature that I am! Let me prove that you have a home wherever I am and for as long as I may live!"

She hesitated, and added in an altered voice, "That is, if you do not find me totally repulsive."

There was a moment of absolute stillness. Jing looked at her, and saw through her outward form, to the bright keen mind within. And his oath of celibacy was to lost Ntah...

They were both very clumsy, but they found it funny, and afterwards he was able to say, in full possession of his rational faculties, "But your father? He cares nothing for our work, and may despise me."

"He is sad and sick and this winter has shown him he too can grow old. He has spoken much about over-close breeding, as one sees with canifangs, and has even mentioned the idea of a grandchild. Inwardly I think I may be normal, and most certainly you and I cannot be cousins to any degree. We shall find out. If not—so be it."

She refolded her mantle about her. Checking suddenly, she said, "Jing, if tomorrow you decide you never want to see me again—if you feel it was only misery which made you desire me—I shan't care, you know. You've given me such a gift as I never hoped for."

"And you," he said fondly, "have given me such courage as an hour ago I thought I'd never enjoy again."

"So you want my ill-starred daughter?" grunted the Count, when with difficulty his attendants had roused him from the mist of dreams in which he now passed most of his time. His ruptured tubules had been unable to heal, owing to his corpulence, and he slumped in his sitting-pit like a half-filled water-bladder. "Well, I always thought you were crazy and now you're proving it. Or have you scried something in the stars to show she's fitter than she looks? Wish you'd do the same for me!"

"I want her," Jing said firmly, "because she possesses a sharp mind, a keen wit and an affectionate nature."

"More than I could say of most of the women I've taken," the Count sighed. "Had I been gifted with a son ... You want a grand celebration? You want mating-presents?" Suddenly he was suspicious.

"Nothing but your authority, Father, to continue our work together as mates as well as friends," said Rainbow.

"Hah! Work, you call it! Wonderful benefits it's brought us all your gabble about stars the naked eye can't see—and the same goes for your people, Jing! Wiped out by plague, so they tell me! Still, you're of good stock, and maybe cross-breeds are what's been lacking in our lines. I'd rather believe too many cousins mated with cousins to keep control of the best homes and richest land, than that I was cursed by the Maker!"

"You are perfectly correct, sir. We too, after all, arc animals."

"Hah! What animal could find more stars in the sky than the sacerdotes say were put there at the Beginning? Oh, take her, and bring me a grandchild if you can. For myself, I'm beyond hope. And—" He hesitated.

"Yes, Father?" Rainbow prompted, taking his claw in hers.

"Dream of me as long as you can after I'm dead. Try not to let the dreams be ugly ones."

"Look, Jing!" Rainbow exclaimed as they left the Count's presence. "The skies are clearing! In a little we shall see the sun!"

But there were other matters to attend to. Qat was weak, and his servants in scarcely better shape. All of them bore plague-scars. Apparently the illness began with sacs of fluid under the skin, accompanied by fever and delirium. If they burst outward, the patient might survive, at the cost of being marked for life. If they burst inward, the victim died. Applying cleanlickers was useless; none could digest the foul matter exuded by the sores. Neither Jing nor Twig had heard of any disease remotely similar.

"Maybe this was what the New Star heralded!" said Qat in an access of bitterness.

"Were that so," Jing responded stonily, "would not I, the most dedicated seeker of its meaning, have been the first to be struck down?"

Thinking how pleased the sacerdotes would be to hear of such a notion.

By then it was midday, and the sun shone clear, albeit not very bright, being at this season close to the horizon. Rainbow was eager to get to the observatory, and Jing—reluctant though he was to abandon these three who might well be his last surviving compatriots—was on the point of consenting to accompany her, when Keepfire came hurrying with news that settled the matter.

"Sir, Scholar Twig is at the observatory with Shine, and they have shown me yet more marvels! Come at once!"

All else forgotten, they rushed in his wake.

"I was right!" Twig crowed. "I did see dark patches on the sun! Now Shine has seen them too!"

"It's true," Shine averred. He had stretched layers of furnimal membrane across branches of walbush so that one might look at the sun through them. Even so, long staring with the tubed lenses had made his eye visibly sore. "And something more, as well!"

"What?" Jing seized the tube.

"Look to right and left of the sun's disc, and you'll notice little sparks! They're very faint, but I definitely saw them. Perhaps they're distant stars, far beyond the sun, which just happen to lie in that direction, but your charts show that some of the brightest stars in that area of sky must lie near the sun right now, and I can't see any of them!"

Jing did not need to consult his maps to know what stars were meant. Bracing himself on a stout branch, he aligned the tube. At first his sight, after the low light-levels of winter, would not adjust, and he saw only a blur.

"Too bright? I can add another membrane," Shine proposed.

"No, I'm getting a clearer view now..." Jing's ocular muscles were adapting with painful speed. "And—oh, that's incredible!"

What he saw was not a blank white disc. There were three dark spots on it. How could that be?

"Do you see the bright sparks?" Shine demanded.

But his vision was overloaded. He stood back, relinquishing the tube, and for a long while was unable to make out his immediate surroundings.

"I was right, wasn't I?" Twig exclaimed.

"Yes," Jing said soberly. "Yes, friend, you were right."

This too must be added to his report on their discoveries. And, given the delay caused by his grief, it could not possibly be ready for the barq presently in harbor here. At all costs, however, it must be sent by the next one. He said so, and Twig objected, "But if we have to take time to write up our findings—"

Jing cut him short. "Did we not pledge to share what we learn with as many other folk as possible?"

"So we did," Twig admitted humbly.

"Well, then! Let's have a score, a score-of-scores, of keen young eyes like Shine's at work on this! I want a full account of our fantastic news in circulation during the coming summer. Even without the resources of Ntah, there must surely still be people on this continent who will respond and imitate what we are doing—and some of them, with luck, may do it better!"

Shine had reclaimed the lenses and was staring through them again. Now he gave a gasp.

"I see half of Sunbride!"

"What?" The others turned to him uncertainly.

"Half!" he repeated obstinately. "Tiny, but perfectly clear—half a disc, like half the moon, and as far from the sun as she ever wanders! Our conclusions must be true! They must!"

VIII

Parchments in one claw, pearlseed in the other, the steersman of the barq about to depart said, "So you want this delivered to your doctor friend in Forb, do you?"

Something about his tone made Jing react with alarm. He said, "The price is fair, surely! If you doubt the quality of the seed, come and see what a jeweltree the Count sprouted from one I gave him last fall. Even during the winter—"

"So you can still grow jeweltrees, can you? When your trencher-plants rot in the ground!"

It was true; with the return of warm weather, the blight which had affected last year's crop was spreading again, and trencher-plant was their staple diet.

"What does that have to do with—?" Jing began. The steersman cut him short.

"Your doctor had better be cleverer than most! We aren't going as far as Forb this trip. The Maker knows whether anyone will want to go there ever again!"

"What are you saying, man?" Jing advanced, clenching his claws.

"The plain truth! Some filthy plague spawned of the far south is rife in Forb, and a murrain is abroad among the livestock, and the very brave-trees are wilting! We've been here three days—how is it this is the first you've heard?"

"I've ... uh ... I've been preoccupied," Jing muttered.

"Dreamlost, more like it!" The steersman returned the parchments with a contemptuous gesture and—more reluctantly—the pearlseed too, adding, "You'll need this to pay for medicine, I've no doubt! If you yourself plan on returning to Forb, which I don't counsel!"

He turned away, shouting orders for his crew to pry loose the barq's tentacles and head down-channel.

"Sure we came by way of Forb," Qat husked. "I told you so. But we aren't sick any more, none of us. Maybe I'm still softer than I should be, but that's a matter of time."

"Yes—yes, of course," Jing muttered comfortingly. He nonetheless cast a worried glance at all three of them: Qat still limp enough to hobble rather than walk, and the boy and girl with their disfiguring scars. Not, according to rumor, that that had prevented their being taken up as curiosities by the younger members of the staff. When even the Count presently approved of outcrossing, and had let his own daughter choose a foreigner for her mate, it was the fashionable thing. Besides, the sacerdotes maintained that no plague could smite those who defied it boldly, so...

Their influence was rising again since news of Ntah's downfall. Was this not, they declared, perfect proof of the Maker's vengeance against those who defied His will? In any normal year, such a claim would have been laughed out of conscience; now, though, the blight on the trencher-plants meant that many families were facing a hungry summer, and famine went claw-in-claw with madness, even when no plague exacerbated the victims' predicament.

Jing had witnessed, on his way hither from Ntah, how precarious was sanity among his folk—how a single year's crop-failure might entrain surrender to the tempting world of dreams. When he paid full attention to his imagination, he was chilled by the all-too-convincing prospects conjured up. The Count's illness was withdrawing one psychological prop from the minds of the people of the valley; it was certain that when he died some of his old rivals from Forb, or their descendants, would come to squabble over his legacy—that was, naturally, if they weren't caught by the plague already. Hunger and sickness might withdraw the others, and then...

Jing trembled at the threat the future held.

Yet his companions declined to worry, even about a means of getting their knowledge spread abroad. If this barq's crew refused to return to Forb, they said, another steersman could be found more susceptible to a handsome payment, more prepared to run risks. It was with some reluctance that they agreed to make extra copies of the parchments Jing had already drafted; Keepfire, of course, could not write, and Twig was constantly on call to administer medicine to the Count. Shine and Rainbow, however, did their best, and by the time the next barq arrived there were six copies of the report at least in summary outline—enough, with luck, for learned folk elsewhere to repeat their studies.

But they, and Jing too, would far rather have continued investigating the dark spots on the sun, and the bright nearby sparks which so far Shine alone had actually seen. Only their sworn pledge, Jing sometimes thought, made them obey his orders. How quickly they were defecting from their brief period of professed admiration!

Could it be because—?

He roused one morning from reverie with a firm and fixed dream-image in his mind, and it was shocking in its import. At once he rushed in search of Twig, and found him coming away from the Count's chamber with a grave expression.

Not waiting for an exchange of greetings, he said in a rush, "Twig, I believe the plague is at work among us!"

Twig gazed soberly at him. He said at length, "How did you know? I thought you said the disease was new to you, and you were unacquainted with its preliminary symptoms."

Jing tensed in horror. He said, "But I guessed it from a dream!"

"Then your weather-sense is far sharper than mine! Did you know the Count attempted to mate with the girl your friend brought here?"

"I'm not surprised, but—No, I didn't know!"

"It was futile, of course, but ... Well, today he exhibits all the signs Qat laid we should watch out for. I'm on my way to check out the other partners she and her brother have engaged with. Have you—? No, forgive me. I'm sure neither you nor Rainbow would consider the idea. But I must ask you a physician's question. Is the Lady Rainbow successfully in bud?"

Jing nodded. "We realized yesterday. Last night we went to the observatory, but there was a bright aurora, so we talked about the future. We're both afraid."

"Internally she's as sound as any woman," Twig assured him. "All the normal pressures are there; only her stance is distorted. But given that the Count, already weakened ... Your weather-sense informs you of what I mean?"

"Even more. Even worse."

"Very likely." Twig hesitated. "Tell me: how did you decide the plague had got a grip here?"

"Because you in particular—forgive my bluntness—seemed to forget your enthusiasm for my leadership so quickly. A pledge is given with full rationality; dreams erode the recollection of it. I don't speak now of your duty to the Count, of course, but it was never my intention to prevent you serving him. It's a matter of priorities."

"You're right," Twig said after reflection. "In my present mood of calm, I see what you mean. Service to the whole world, which can be performed by spreading our knowledge, is more important than service to an old man whose life I can't prolong with all my skills. We must get those reports away at once, in all possible directions. I'd have realized this truth myself but that—yes, you guessed correctly: I'm being pestered by hideously persuasive dreams such as I haven't known since long before I came to Castle Thorn. And fever due to the onset of the plague would best explain that."

"I think I must believe the same," Jing muttered.

"Oh, no! You of all people! No, you must survive! It would be unbearable to think that the greatest discoverer of our age must be struck down randomly! Far better you should escape to tell the world your tale!"

But I've kept company with Qat," Jing said stonily. "Out of nostalgia, I've spent half-days at a time talking with him and neglecting my own greater duty. Miraculously I believe Rainbow still to be unaffected. She and the child she buds must go away and take our reports. Might I beg you to attend her before you continue with other matters?"

"Yes! Yes, certainly! But I must warn you that nothing I say or do can alter an established fact. She may already—"

"I know there's a risk. I want to diminish it. We'll buy the steersman of the next barq, give him all my pearlseeds so he can make for the great ocean and find one of the monster barqs that legend says can ply across it to another continent."

"Legend? You want to trust in legends now? Surely you must after all be afflicted!"

"I speak out of imagination rather than dream—though the two sometimes become so intermingled ... Yes, I think there's no alternative. In one of the visions which haunted me this morning, I saw the bravetrees of Forb rotting from the base wherever a corpse had been deposited. What manner of sickness can attack trees as well as people?"

"A new kind," Twig said slowly.

"As new as the New Star?"

"Ah, but it was only a dream-guess!"

"I think we'll see the same when the first victims die at Castle Thorn."

Clenching his claws, Jing added as he turned away, "I wish with all my might it may just be a dream. But I fear it may well be correct imagining. The blight upon our trencher-plants, at any rate, is real enough."

IX

When next they heaved the Count out of his sitting-pit to cleanse and salve him, there were the betraying sacs beneath his skin. And they were readily recognized, for a girl at one of the outlying villages who had partnered the boy from Ntah had died from their inward rupturing that very day.

Instantly the sacerdotes announced that this was the doom pronounced by the Maker against anyone who harbored heretics from foreign lands, and in the grip of the fever which preceded the visible outbreak of sores the peasants forgot what those same sacerdotes had been saying only days earlier about confronting the risk of plague with boldness. Keepfire managed to prevent his family and followers from being deluded from one of the confusing visions that now beset him, part sane imagination and part lunatic dream, Jing almost extracted a clue concerning life below the massive layers of rock that sheltered Twig's laboratory, but it evaded him at last because he cared more about the survival of his wife and child.

For a little it seemed that Hedge and Bush were certain to escape, which would have dealt a logical blow to the sacerdotes' argument, especially since Twig's sole ulcer had burst outward and his cleanlickers proved able to deal with it. All three had been particularly close with Jing, and it was being claimed that associating with the Ntahans was the key to guilt and the Maker's punishment. But the day came when Bush succumbed, and admitted contact with the Ntahish girl, and a frenzy of hate exploded like one of the geysers that snowbelong-hunters reported far to the north.

"On the way to the observatory they set their canifangs at me," Rainbow said. "Only Sturdy's quickness with his prong prevented me from being badly hurt."

They sat in her bower, high in the castle and well defended, at a time when normally the night would be quiet but for distant icefaw screams and maybe a little music.

They all cast uncertain glances toward Sturdy. Were a trained prongsman to become delirious before he was restrained there could be considerable slaughter, especially when reflex due to killing had already been established in his mind. And killing canifangs was normally no part of an escort's duty.

Still, there were no marks to be seen on him.

"It's essential now for you to get away," Twig said to Rainbow. Her condition was barely perceptible, fortunately, owing to her lopsidedness. But her attendants could not be trusted to keep such a secret. Let the sacerdotes once get news of it, and they would no longer be confronting angry peasants, but a systematic series of clever attempts to frustrate the budding.

Jing drew a deep breath. "You don't yet know how essential," he said, and spread the right side of his mantle in a manner he would never normally do in anybody's presence except hers ... but these were intimate friends.

"You too!" Twig blurted as he recognized what Jing was now revealing.

"It would appear," Jing said with all the detachment he could command, "that even those who make a good recovery, like Qat and his companions, still carry the plague with them."

"I'll kill him! I'll kill Qat!" Shine screamed, erupting to his full height. "He's going to deprive us of—"

"You will do no such thing," Jing decreed. It was strange, he reflected, how cold he felt, when he knew abstractly that he must be in the grip of fever. Just so long as he could continue to separate dream from reality ... "You will hew to your oath. You will undertake the protection of Lady Rainbow and her bud and all the parchments on which we have copied details of what we have discovered. You will escort her away from Castle Thorn before the peasants storm it, which will doubtless be the day after they notice its bravetrees rotting where corpses have been consigned to feed the roots." This, with a meaningful glance at Twig. "I have no homeland. I have no future. I have used my life as it befitted me to do. You have sometimes appeared to look on me as a substitute for the imaginary Maker who so long ruled your life. I'm not a god. If there is one, He watches us but does not interfere. He speaks to us, perhaps, but if His voice is couched in the language of the stars it's up to us, not Him, to spell out the message ... Oh, I ramble!"

"Not at all!" cried Shine. "You tell me what I most need to be told!"

"Believe it when I'm gone, and you'll do well," Jing said. Already he could feel the sac he had exposed starting to throb. "Now, take the future in trust. You here—you, Shine; you, Scholar Twig; you, Keepfire, who made us the tools to reveal unknown truth; you, my lady, who bear something of me which would otherwise be as hopelessly lost as Ntah itself—all of you must listen to my words and cherish what I say as proudly and as fiercely as when we took our oath. And by the way, Shine!"

Humbly the ex-sacerdote looked a question.

"Don't ever speak again of killing. Qat will die young; he was weakened anyhow by his suffering. Or it not, some crazy fool with a mindful of lunatic dreams will dispose of him. But this is neither justice nor vengeance. No, we must speak always and forever of life instead of death; we must fight the foolishness of dreams and concentrate on sanity. We must feed and shelter and educate our people, until the day dawns when we know how to conquer sickness and famine, blight and murrain. Then, and only then, shall we be fit to understand the message of the sky. Then, and only then, will the tools Keepfire created for us fall into the proper claws. And yours too, Twig, and mine—the star-charts created by my people ... my former people."

He was briefly silent, and the pause was full of sorrow.

"But let nothing that has been well done go to waste!" he resumed at length. "Not that it can, if it's recorded in the stars ... but we don't speak that language yet, and maybe it will be a long time before we do. Knowing now how many more stars there are than we believed, we must never be arrogant again! In all humility, going as it were in a mental crouch, we must patiently await the time when we are entitled to stand up to our full height, and that height shall reach the stars to take them in our grasp like ripened fruit! I say to you—"

At that moment he felt the sac under his mantle rupture.

Inward.

While they looked at him in wonder, for his peroration had been charged with the same power which persuaded them to join him in their common pledge, he said gently, "I am as good as dead, my friends. Tomorrow I shall surely be insane. I speak to you with the last vestige, the last shred, of what was Ayi-Huat Jing, court astrologer to His Most Puissant Majesty Lord Waw-Yint of Ntah, who set forth upon a journey longer than any of his nation previously, and must now die as my nation died. Dream of me. Make others dream of me. Or all my work will go for naught."

He added silently, "Would I had said that in my own speech. I could have expressed it so much better..."

X

The day after the Count's death, another of the regular barqs came to the castle wharf. Her steersman was horrified to learn that the plague was here ahead of him, and was in mind to put about at once and risk her starving under him on the return trip. But Twig ceded him all the pearl-seeds left in Jing's store—enough to buy the barq and her crew a score of times over—and he was reassured that at least this journey would not be as fruitless as he had feared. The peasants were in the grip of delirium; only the precarious loyalty of Sturdy and the other prongsmen kept them at bay while Rainbow and Shine, in obedience to Jing's order, scrambled on board with the precious parchments.

"But where shall we go?" the steersman cried. "Forb is rotting like a blighted fungus! I saw its bravetrees lean towards the river as though they had been snapped by gigants!"

"Any place the water carries you away from plague!" Twig retorted. "Do they not tell of folk who ply the ocean aboard barqs that make yours look like half-grown pups?"

"We'd have to chance the rapids of the Sheerdrop Range!"

"Then chance them, on a route you never dared before! It's better than the certainty of plague!" Rounding on the prongsmen, Twig ordered them to prod loose the barq's tentacles despite her groans of hunger.

"Won't you come with us?" Rainbow shouted. "Even if—"

"Your father's dead. Your husband told me he would rather you did not watch him follow the same course." Twig descended to the wharf's edge and gently touched her claw. "No, Shine is to take care of you now. I've had my life, as Jing had his. If only we could read the stars more clearly, we might know why. But what you bear with you will instruct the future. You are the wife, my lady, of the greatest man it's been my privilege to know. Create a posterity for him. If the bud fails, then do so anyhow. I cannot; I'm old and weak and I must resign myself to facts."

"If by some miracle—"

"Qat has told us positively there are no miracles with this disease. Only if the sac ruptures to the outside like mine ... and Jing's did not."

"Couldn't you have made it rupture?"

"That too was tried, in Ntah. It always failed."

The steersman was glancing nervously from one to other of them. He said, "If this woman has the plague-mark on her—"

"No, she does not!" Twig flared. "That's precisely why we want to get her out of here! You have pay for twenty voyages! Go as far as you can, go anywhere you can, and deliver our message to the world. Next time, perhaps, we may know enough about the universe to conquer such a plague! But without the information that you carry, someone else in the far future will have to start all over again! Oh, get under way, will you? The castle will be stormed within the day!"

The steersman flogged the barq's tentacles, and they unwillingly let go their grip; she put about and made down-channel. Watching, Keepfire— who had had the chance to travel with Rainbow, but refused because he feared the water more than fire—said, "Do you think, sir, that our work has gone to waste?"

"I sometimes fear it, sometimes think it can't," was Twig's reply. "Sometimes I feel it's like the seed funqi sow on the spring wind, so numerous that a few at least must find a lodging in good ground; sometimes I can imagine it being like a trencher-plant, at risk from unknown kinds of blight predicted or maybe not predicted by the New Star ... At all events I know one thing. We are to consign the remains of Master Jing to your hot pool, instead of to a pool with fishes in or the roots of a tree."

Startled, Keepfire said, "This is to do more honor to me and my family? Sir, it's already been enough!"

"Not honor," Twig sighed. "He said when he still possessed some trace of rationality that he'd been told how hot pools can break up a dead animal. Did Hedge or Bush mention this, or was it you?"

"I think I did!" said Keepfire with a trace of pride.

"He wants to die more completely than anyone before, dissolved if possible into his finest shreds. He wants to leave a legacy of health and information, and not a rotting body to convey more plague. Come with me. He said he had chosen to die on the departure of his wife, and when we enter his chamber we shall find a corpse for sure."

"But we shall dream of him," said Keepfire, following. "We shall make sure he is dreamed of for all time."

PART TWO

FUSING AND REFUSING

I

After half a score of days the storm was over. Weather-sense and a familiar, reassuring noise lured Skilluck back from the dreamness whither he had been driven by exposure, privation and sheer terror. Slackening his mantle, he relaxed his death-grip on the pole he had clung to while he was reduced to primitive reflexes, concerned only to escape the fury of the elements as his ancestors might have hidden from a predator larger than themselves.

The sound he had recognized was the unmistakable munch-and-slurp of Tempestamer feeding.

Weak exultation filled him. Surely she was the finest briq ever to set forth from Ushere! He had pithed her personally with all the expertise at his command, leaving untouched by his prong nerves which other Wego captains customarily severed. At first his rivals had derided him; then, however, they saw how docile she was, and how fast she grew, and in the end came begging a share of his knowledge, whereupon it was his turn to scoff. Now she had proved herself beyond doubt, for she had defied the worst weather in living memory and—he looked about him—brought her crew to a safe haven, in a bay landlocked among low hills and sunlit under the first cloudless sky he had seen in years.

But where that haven was, the stars alone could tell.

With agony stabbing through his every tubule, he forced himself more or less upright, though it would be long before he regained his usual height, and uttered a silent blessing for his name. Those of his companions who had been called by opposites—Padrag and Crooclaw—had been lost overside on the third day of the storm. But the rest, better omened, were in view, though still unaware: the boy Wellearn, whose first voyage had come so near to being his last, and Sharprong, and Strongrip, and Chaplain Blestar ... Was the chaplain also alert? His voice could be heard mumbling, "Let each among us find his proper star and there add brightness to the heavens in measure with his merit in the world..."

But—no. His prayer was mere reflex. He was still lost between dream and imagination. And in a bad way physically, too; his mantle was bloated and discolored, a sure sign of cresh. The same was true of the others, and Skilluck himself.

For an instant the captain was afraid he might be dreaming after all, that he was so near death he could no longer distinguish reality from fantasy. But in a dream, surely, he would seem restored to health.

His pain was receding, although the areas where he had rubbed against the pole during the storm would remain sore for a long while. He forced himself to set out on a tour of inspection. One piece of essential equipment remained functional: the northfinder, tethered in its cage, responded weakly to his order and uncoiled itself in the correct direction. Also his precious spyglass had been so tightly lashed to a crossbar, all the gales and waves had not dislodged it. That apart, things looked grim. Most of Tempestamer's drink-bladders had burst, the trencher-plants had been so drenched with salt water they looked unlikely to recover, the vines had been torn bodily away leaving raw scars on the briq's bide, and—as he already knew—their reserves of fish and pickled weed had been used up.

He sipped a little water from an intact bladder, struggling to make plans. Food must come first, and more water. Were there edible plants on this strange shore? Was there any chance of trapping a game-animal? He needed the spyglass to find out. But his claws felt weak and clumsy, and the rope was swollen with wet; the knots defied him.

A shadow fell across him. He glanced round, expecting Sharprong or Strongrip. But it was young Wellearn who had joined him, hobbling along at barely half his normal height.

"Where are we, Captain?" he croaked.

"No idea, but I'd rather be here than in mid-ocean. Take a drink—but slowly! Don't try and put all your fluid back at one go, or you'll burst a tubule. Then help me untie the spyglass."

Despite the warning, he had to stop Wellearn after several greedy gulps.

"There are three more of us, you know, and only three full bladders!"

Wellearn muttered an apology and turned his attention to the knots. After much difficulty they loosened, and Skilluck unwrapped the hide around the tube.

"Take drink to the others. But be careful. The state they're in, they may not know the difference between you and food. Or themselves, come to that. I guess you never saw anyone with cresh before, hm?"

"Is that what we've got?" Wellearn's eye widened in horror. "I heard about it, of course, but—well, what exactly is it?"

"Who knows? All I can say is, I've seen a lot of it at sea when our trencher-plants got salt-poisoned and our vines were blown away, same as now. Most people think it comes of trying to live off stale pickles. Makes you leak, drives you into dreamness, kills you in the end ... Oh, curse the weight of this thing!" Skilluck abandoned his attempt to hold up the spyglass normally, and slumped forward in order to rest its end on the ridge of the briq's saddle. "I bet we'll be seeing cresh on land again one of these days, if the winters go on getting longer and harsher and seeds don't sprout and fish don't run ... But you shouldn't worry too much about yourself. It always hits the biggest and strongest first and worst. Dole out a sip at a time and be specially wary of Blestar—he's delirious."

Carefully filling a gowshell from the drink-bladder in use, Wellearn heard him continue, mainly to himself: "Not a trencher-plant to be seen. Don't recognize a single one of those trees, don't spot a single animal. No sign of a stream unless there's one behind that cape..."

The boy shivered, wondering whether his own mantle was as patched with creshmarks as the others', and the captain was speaking only to reassure him. All things considered, though, he felt remarkably well after his ordeal: weak and giddy, of course, so that he wondered how he would fare if he had to leap clear of a cresh-crazed crewman; thirsty in every fiber of his being; and hungry to the point where he wished he could browse off floating weed like Tempestamer. Yet he was still capable of being excited about their arrival in this unknown region, and that was an excellent sign.

So Skilluck must be telling the truth. Sharprong, on the other claw, was almost too ill to swallow, and neither he nor Strongrip had the energy to attack a helper. Ironically, Blestar was worst off of them all, his mantle cobbled with irregular bulges as though it were trying to strain outward through a badly patterned net. He was talking to himself in a garbled blend of half a dozen learned idioms. Wellearn recognized them all; it was his quickness at language that had earned him a place among the crew. Their mission was to trade hides for food-plant seeds in the hope of cross-breeding hybrids which would grow very quickly during the ever-shortening northern summer. Many briqs this year had scattered on the same quest. If it failed, the Wego might have to move south en masse, and the hope of finding habitable but unpopulated lands was dreadfully slim. So there would be fighting, and the weakened northerners might lose, and that would be the end of a once-great folk. At best they might leave behind a legend, like Forb or Geys or Ntah...

Tormented by the sun, Blestar was reflexively opening his mantle as though to roll over and cool his torso by evaporation. Wellearn had never been in such a hot climate before, but he knew enough to resist the same temptation; in their dehydrated state it could be fatal. Anxiously he wondered how he could provide shade for the sick men, and concluded there was no alternative but to untie one of their precious remaining bales of hides. The outer layers were probably spoiled, anyway.

He contrived to rig two or three into an awning; then he distributed the rest of the fresh water and returned to the captain, dismayed to find him slumped in exhaustion.

But he was alert enough to say, "Good thinking, young'un. Give me a little more water, will you? Even holding up the spyglass has worn me out. And I don't see very clearly right now. We'll have to wait until Tempestamer has finished feeding and see if we can make her beach herself."

"Sharprong told me she hated that," Wellearn ventured.

"Oh, she does, and I'd never try it normally, of course. But that's our only hope; we've got to get ashore! Maybe while she's digesting she'll be tractable. Otherwise I'll have to pith another of her command nerves, and if I miss my mark because she bucks and bolts, then the stars alone know how we'll find our way home—Did you give water to the northfinder?"

"I didn't think of that!" Wellearn exclaimed, and hastened to remedy his oversight.

Returning, he looked at the ruptured drink-bladders, wondering whether any were likely to heal. But they were past that, hanging in salt-encrusted rags. In time Tempestamer would grow new ones, but it might be a score of days before they were full enough to tap. There was only one thing to be done.

"I'm going to swim ashore," he announced.

"You have got cresh! You'd never make it." Skilluck brushed something aside. A strange kind of winget had settled on him; others, all equally unknown, were exploring the briq, paying special attention to the scars left by the uprooted vines. It was to be hoped they were not in breeding phase, for the last thing Tempestamer needed right now was an infestation of maggors.

It occurred to Wellearn that in these foreign waters there might be creatures as hostile as the northern voraq, but Tempestamer showed no sign of being pestered by any such. He answered boldly, "There's no alternative! If I don't find water I can at least bring tree-sap, or fruit, or— or something."

"Then unlash a pole to help you float," Skilluck sighed. "And take a prong in case a waterbeast attacks you."

After that he seemed to lose interest in reality again.

The water was deliciously cool as Wellearn slid overside, but he was aware how dangerous salt could be to someone with a weakened integument, so he wasted no time in striking out for shore. His mantle moved reluctantly at first, but he pumped away with all his strength, and the distance to land shrank by a third, by half, by three-quarters ... It was more than he could endure; he had to rest a little, gasping and clinging to the pole. To his horror, he almost at once realized he was being carried seaward again, by some unexpected current or the turn of the tide.

Although fatigue was loosening his grip on reality, he resumed swimming. The sunlight reflected on the ripples hurt his eye, and salty splashes stung it; countless tubules cried pain at being forced to this effort without sufficient fluid in his system; fragments of dream and all-toc vivid imaginings distracted him. He wanted to rest again, relying on the pole, and knew he must not. At last he let it go, and the prong with it, for they were hindering too much.

After what felt like a lifetime, smooth rock slanted up to a little beach, and he crawled the rest of the way as clumsily as a new-budded child. Cursing his bravado, he forced himself across gritty sand that rasped his torso, and collapsed into the shade of bushes unlike any he had ever seen before. Some sort of animal screamed in alarm and branches fluttered as it fled; he could not tell what it was.

In a little, he promised himself, just as soon as he recovered his pressure, he would move on in search of water or a recognizable plant, or risk sampling something at hazard, or...

But he did not. After his exertions, cresh had him in its deadly grip, and he departed into a world of dreams compound of memory, so that the solid ground under him seemed to rock and toss like the ocean at the climax of the storm. He did not even have the energy to moan.

From the briq Skilluck saw him fall, and let go the spyglass with a curse, and likewise slumped to his full length. The pitiless sun beat down and, all unheeding. Tempestamer went on gulping weed to cram her monstrous maw.

II

He was looking at himself.

Wellearn cried out. He had seen his reflection before, but only in still water, which meant he should be lying down on the bank of a pool. Every sense informed him he was in fact sitting up. Yet his image was confronting him. He was certain it must be confect of dreamness.

Suddenly it swerved aside and vanished. Struggling to accept he was not after all lost in sickness-spawned delirium, he discovered he was now seeing two people taller, slimmer, and with paler mantles than his own folk: a grave elderly man and a most attractive girl.

The former said something Wellearn did not quite grasp, though a tantalizing hint of meaning came across. Then, touching his mandibles with one claw, he said, "Shash!"

Imitating him, the girl said, "Embery!"

Clearly those were their names. Wellearn uttered his own, followed by greetings in his native speech. Meeting no reaction, he switched to others, and as soon as he tried Ancient Forbish Embery exclaimed in amazement.

"Why, you speak what we do!" she said, her accent strange but her words recognizable.

How then could Wellearn have failed to understand before? And now again, as she said something too rapid to follow?

"The language changes," Shash said slowly and clearly. "It has been a score-of-score years since our ancestors settled here. Use only the oldest forms. Wellearn, you comprehend?"

"Very well!"

"Do you remember your voyage hither?"

"The greater part of it." But where was here? Wellearn looked about him, realizing for the first time that he was in a noble house. Never had he seen such magnificent bravetrees—except they weren't exactly brave-trees—or such a marvelous array of secondary plants. Had he been hungry, which to his amazement he was not, he would at once have asked to sample the delicious-looking fruits and funqi which surrounded him.

Light slanted through gaps between the boles, which offered glimpses of what looked like a great city. The air was at high pressure and very warm, though not so oppressive as when he swam ashore, and the scents borne on it were absolutely unfamiliar. But one matter must take precedence over the curiosity that filled him.

"My companions! Did you save them too?"

"Oh, yes. They are sicker than you, but we hope to cure them soon."

"But I had cresh..." Wellearn hesitated. In his people's knowledge there was no remedy for that affliction. Sometimes it went away of its own accord, no one knew why; more often its victims were permanently crippled.

"No longer. You saw for yourself. Where are the marks?"

"I saw," Wellearn agreed slowly. "But I didn't understand."

"Ah. Embery, show him again."

This time he was able to make out how it happened. She held up a large disc, very shiny, which gave back his reflection. Touching it diffidently, he discerned a peculiar coolness.

"Metal?" he ventured.

"Of course. But your people understand metal and glass, surely? We found a telescope on your briq, as good as our own."

"Captain Skilluck got it in trade," Wellearn muttered. "I can't say where it was made."

"Do you not know and use fire?" Shash demanded in surprise.

"Of course, but in our country there is little fuel and it's too precious to be used for melting rocks. Long ago the weather, they say, was warmer, but now in winter the sea freezes along our coasts, and then it's our only means of staying alive."

"Whiter," Embery repeated thoughtfully. "That must be what we read about in the scriptures, the time of great cold which happens once a year and lasts many score days."

And yearly it grows longer ... Wellearn suppressed a pang of envy. What a privilege to live in latitudes where winter never came! He had heard tales about such places from boastful old seafarers, but he had never expected to wind up in one on his maiden voyage.

Yet those same travelers always claimed that they found something grand in the country of their budding, something noble and challenging about its harsh landscape. He must not think of worse and better until he knew much more.

"May I see my companions?" he requested.

"Certainly, if you're fit enough," Shash answered. "Can you stand?"

Wellearn concentrated on forcing himself upright. He managed it, though he could not regain his normal height. Even had he done so, he would still have been overtopped by these strangers, who must be as tall as mythical Jing—or maybe not quite, for he was said to have been taller than anybody.

"Let me help you," Embery offered, moving to support him. Contact with her was very pleasant. He wondered what the local customs were concerning mating. The Wego themselves welcomed visitors in the hope that outcrossing would bring more and healthier children, for they were barely keeping up their numbers, and he had been told that many foreign peoples felt the same. But it was too soon to think of such matters.

In an adjacent bower Skilluck lay in a crotch made comfortable with masses of reddish purple mosh; he was still not alert but the creshmarks were fading from his mantle. Others beyond held Strongrip, Sharprong, and Blestar, who was visibly the worst affected.

"I've never seen such a severe case," sighed Shash. "One could almost imagine he had weakened himself deliberately."

Wellearn nearly admitted that in fact he had. It was the custom of chaplains, in face of danger, to fast in the hope of being sent a vision from the stars that would save them and their comrades. There was no recorded instance of it happening, but the habit endured.

These people, though, might have no faith in visions, and he did not wish them to mock the strangers who had fallen among them. Instead he voiced a question that was burning in his mind.

"What manner of place is this?"

"A healing-house," Shash replied, and added wonderingly, "Do they not have such in your country?"

"A great house like this, solely for sick people? Oh, no! We're lucky to have enough for those who are well. Sometimes they die, and the occupants must take refuge in caves, or pile up rocks for shelter ... I'm amazed! When we arrived in the bay, we thought this region was uninhabited!"

"Ah, you were the wrong side of the cape. People rarely visit that bay except for glassmakers needing sand or fisherfolk like the ones who spotted your briq."

"Tempestamer!" Wellearn clenched his claws. "What of her?"

"We have small knowledge of matters of the sea, but we have guarded against her wandering off by fixing strong cables across the mouth of the bay. However, she's so huge ... Will it be long before she needs to feed again? She's practically cleared the bay of weed."

"I'm afraid you'll have to ask the captain. Usually she only feeds by night as she swims along, but she must have been half-starved after the storm that drove us here."

"Hope then that the captain recovers shortly. We're doing our utmost for him. Look, here come curers with more creshban."

Wellearn turned in the indicated direction, but almost literally while Shash was speaking, it grew dark. He gasped. Then festoons of luminous creepers reacted, faster than any gleamers he was used to, coming up to full brightness nearly before his vision adapted to the lower light level, and he saw two husky youths each bearing a round object like an immense nut. There was a sudden pungent smell, which reminded him of a taste that had haunted his long period of dreamness. Also he recalled terrible hunger, and having to be restrained for fear he might attack those who were holding him ... But that belonged to the past, and in the present Shash was saying, "You must continue the medicine for several days yet. Drink some more now."

Wellearn complied. The nuts were hollow, and contained a bitter liquid of which he managed a few gulps.

"If we could only plant such nut-trees on a briq!" he muttered.

"It's not their natural juice," said the curer who had given him the drink. He spoke without Shash's deliberateness, but by this time Wellearn was adjusting to the local accent. "It's mixed with sap from half a score of plants."

Visions of saving the lives of countless future mariners bloomed and wilted in Wellearn's imagination. He said grumpily, "And I suppose not one of them grows in the north?"

"Later we can show them to you and let you find out," Shash promised. "But now I think you should return to rest."

"I couldn't! I'm too eager to see the marvels of your city, and meet more of its people!"

"In two or three days' time, perhaps. Not right away."

"May I not at least look out at the city, and question someone about it?"

"I'll oblige him, Father," Embery said, and added self-mockingly, "That is, if he can understand me."

"In my young days," Shash sighed, "people your age were wise enough to know when their elders were giving them advice for their own good ... Oh, very well! But remember, both of you, that the workings of cresh are insidious, and over-excitement is as fast a route as any into dreamness!"

Embery guided Wellearn to the top of the highest tree in the house, which offered a clear view in all directions. The moon was down and the sky was clouding over in a way that upset his weather-sense, but he was too eager to worry about the risk of a lightning-strike. From here the outline of the city was picked out by glowing creepers and funqi, and he was shaken by its huge extent. It even marched over the crest of a hill inland, beyond which faint redness could be seen.

"That's where the fireworkers live," Embery explained. "They make glass and metal—they made the mirror you've seen. The area is sheltered, the wind almost always carries the smoke away from us, and it's easy to find fuel in that direction. They use vast quantities, you know. Some of their furnaces ... But you have to see them."

Over and over she said the same, when describing the outlying farms, the giant nets which fish-hunters hurled by means of weights and long poles far out to sea from the nearby capes and islands, the work of those who bred mounts and draftimals—"like your briq," she added merrily, "only smaller and going on land!"—those who trained new houses to replace old ones or spread the city on fresh ground, and more and more until Wellearn could scarcely contain himself. How desperately he wanted to explore every nook of—

"I haven't asked your city's name!" he exclaimed.

"Hearthome."

It was apt. "How many people live here, do you know?" he pursued, thinking perhaps not a great number, if each of five sick strangers could be allotted a separate bower, and then yes a great number, if so many extra houses had been sown.

"Nine score-of-scores, I think, though some say ten."

It was unbelievable. The Wego numbered perhaps a fifth as many. Oh, this must be a better land to live in!

"But there are far larger cities inland and all along the coast," Embery said. "Many have a score-of-score-of-scores. None is as rich as Hearthome, though."

"Why is that?"

"Because we are the folk who work hardest at discovering new things. Travelers from a moonlong's journey away come to learn from people like my father, and my uncle who lives yonder"—she pointed in a direction diametrically opposite the furnace-glow—"and devotes his time to studying the stars."

Among Wellearn's people the stars were of little save religious interest. During his entire life at home he had seen a clear sky so seldom he could almost count the total. Before the adoption of the northfinder—a creature which, properly pithed, would always seek out the pole—it was said mariners had been guided by the stars on outward voyages. The return, of course, was never a problem; briqs like Tempestamer could be relied on to retrace their course. Though after such a tremendous storm even she...

Dismissing such gloomy thoughts, albeit making a firm resolution to utter thanks, just in case, to the ancestors who—according to the chaplains—must have been watching over him during the voyage, he made shift to repeat a traditional Forbish compliment which Blestar had taught him when he was first apprenticed to the trade of interpreter, and of which mention of the stars reminded him.

"Ah!" he said. "Starbeams must shine on Hearthome even when the sky is cloudy!"

"Why not?" Embery returned. "After all, we are honest followers of Jing."

Wellearn drew back, startled.

"But he was only a legend! Tales about him are compound of dream-stuff!"

"Oh, no!" She sounded scandalized. "True, there is a great dream in his scriptures, but even that is in perfect accord with reality. Have you never studied his teaching?"

At the same moment thunder rolled, but it was not the shock to his weather-sense which made Wellearn's mind reel.

"Your father was right after all about my need for rest," he husked. "Kindly lead me back to my bower."

Where he spent long lonely hours wondering what—after teaching and believing all his life that tales about folk who conjured secrets from the stars were mere superstition—Blestar was going to say when he discovered himself in a land where Jing was real.

III

Skilluck's shattered mind crawled back together out of pits of madness and he could see a figure that he recognized. It was Wellearn, addressing him anxiously: "Captain, you're alert again, aren't you?"

Beyond him, unfamiliar plants hanging on what were not exactly bravetrees, immensely tall strangers whose mantles were astonishingly pale ... They coalesced into a reality, and he was himself and whole and able to reply.

"Tell me where we are, and how Tempestamer is, and how these people treat us."

He was proud of being able to phrase that so soon after regaining normal awareness.

Wellearn complied, but half the time he was almost babbling, plainly having been cozened by the wonders of his first foreign landfall. Skilluck was a mite more cynical; he had spent half his life traveling, and more often than not he had been cheated by the outlanders he tried to deal with. The harsh existence led in northern lands was no school for subtleties of the kind practiced by those who dwelt in southern luxury ... and it had been obvious, when Tempestamer came to harbor, that she had been driven further than any of the Wego had wandered before, perhaps to the equator itself.

So he merely registered, without reacting to, most of what Wellearn said, until a snatch of it seized his interest.

"—and they have a certain cure for cresh!"

At once Skilluck was totally attentive. Cautiously he said, "It works on everybody, without fail?"

Mantle-crumpled, Wellearn admitted, "Not on all. Blestar, they say, may well not survive. But for me and you, Sharprong and Strongrip, it's proved its worth!"

"Do they understand what we're saying to each other?"

"N-no! And that's something else amazing!" Wellearn blurted. "I have to speak to them in Ancient Forbish!"

Skilluck was unimpressed. His explorations had often brought him to places where relics of that once widespread speech survived. Blestar even maintained that many Forbish words had found their way into Wegan, but since they all had to do with fire and stars—things everybody knew about, but in which the chaplains claimed a special interest—sensible people dismissed such notions as mere religious propaganda. Wego seafarers took chaplains along much as they carried pickles: just in case. The best trips were those where they weren't needed.

Of course, their services as interpreters...

He forced himself to sound very polite when next he spoke to Wellearn.

"It seems we should behave to our hosts in the friendliest possible fashion. I guess at something we might do for their benefit. How goes it with Tempestamer?"

"That's what I'd just been asked to tell you! She has grazed the bay where we landed clean of weed, and the cables they've strung across its mouth won't hold her much longer, and they fear for their inshore fishing grounds."

"Let the cables hold but one more day, and I'll put her to sea and feed her such a mawful as will content her for a week. And I'll come back, never fear. A cure for cresh—now that's something worth making a storm-tossed voyage for!"

"There's more," Wellearn said after a pause.

"So tell me about it! Anything we can trade for, I want to hear!"

"I'm not sure it's the sort of thing one can trade," Wellearn said. "But ... Well, these people have shown me Jing's original scriptures. Or not exactly the originals, which might rot, but accurate copies. And they tell about how the stars are fire and our world will one day go for fuel to make the sun brighter and ourselves with it unless we—"

Skilluck had heard enough. He said as kindly as he could, "Boy, your brush with cresh has affected your perceptions. I counsel you to concentrate on growing up. A little worldly wisdom would do wonders for you."

Wellburn bridled. "Captain, do you know Forbish?"

"I've never taken lessons, if that's what you mean!"

"I have! And the documents I've been shown while you were lying sick have satisfied me that Jing was real!"

Worse and worse ... Skilluck forced himself to an upright position. He said as emphatically as he could, "Since you oblige me to prove that our people are not all crazy, tell our hosts that I shall at once reclaim command of Tempestamer!"

"But you're not fit!"

"Let me be the judge of that!" Skilluck was struggling to bring his pads under control. "I must—"

But his pressure failed him. He was compelled to slump back to a sitting position, whence he glared at Wellearn as though it were the boy's fault he was so weak.

There was a rapid exchange in Forbish, and Wellearn stated authoritatively, "Shash is the curer-in-chief here. He says you must drink creshban for at least another day before you leave this healing-house."

With a trace of mischief in his tone, he added, "I didn't tell him that was how long you already estimated would be necessary."

At home, mocking his briq-captain in that way would have led to punishment—perhaps lasting punishment, such as having one of his tubules punctured where it would never heal. Since arrival here, though, Wellearn had regretted his oath of fealty, and decided that if all else failed, he could put himself under the protection of the Hearthomers. What did he have to look forward to if he went back to Ushere? More and more hunger, more and more misery! He had never seen cresh on land, as he had told Skilluck, but he had seen old folk lose their minds, reduced to such a state that they scarcely reacted except when they were fed like hoverchicks or barqlings, or when some young'un was brought to them to be mated because a wise'un claimed there was still virtue in that line despite appearances. It had been happening to Wellearn since it became obvious that he was among the lucky bright few, and there were no memories so revolting in his short life as those which reminded him of the foul mindless gropings he had undergone with starvation-crazy ancients. Not one—praise the stars!—of his encounters had so far led to offspring, but if he went home he would certainly be compelled to do the same again, and once the smell and touch took over...

He shuddered. And wondered much about the nature of the stars which could dictate so cruel a doom for a person as well intentioned as himself, then pay him back—for it seemed to him to be a reward—with the gentle sweetness of Embery. She had received him twice already, and her father thoroughly approved, for as he said, "We too in this delicious land are plagued by forces we don't understand, and it has been nearly a score of years since one of our family bred true: myself with the lady who gave me Embery and died."

What, on the other claw, they did understand had not yet ceased to astonish him.

Leaving Skilluck's bower, he was overcome by memory.

...Behind the inland hills, a valley lined with smoke-blackened rock; heaps of charcoal, even blacker, surrounding cone-shaped furnaces; piles of sand and unknown minerals, green and brown and white and red; sober folk all of whose names ended in -fire, claiming spiritual if not physical descent from Jing's legendary friend who lived underground yet brought the light of heaven forth from a cave— Wellearn knew all the stories, for he had been told them as a child, but later he had been taught to think them fabulous, whereas the Hearthomers took them literally, and by their guidance produced incredible ingots of metal and unbelievable quantities of pure glass. Beyond, a desolation as complete as though a hurricane had laid the vegetation low for a day's walk or more, which was being systematically replanted with oilsap trees that grew quickly and burned hotter than even the best charcoal.

...In a fine house overlooking the sea, an elderly couple possessed of tiny miracles in the shape of roundels of glass no larger than a raindrop, but perfectly shaped, through which they showed him the secret structure of plant-stems, funqi, his own skin, immensely magnified, as though a telescope were to look down to the small instead of upward to the large!

...In a grove just outside the city, folk who selectively bred meatimals, burrowers, diggets, mounts, draftimals, and a score of creatures he could put no name to, seeking to make them fatter or more docile or in some other way more useful. Their cleanlickers were said to be unique, capable of ridding any wound of its poison within days and making a swift recovery. To take a few of those home to the lands where so often a daring fish-hunter died for his temerity in defying a rasper or a voraq: that would be an achievement! But what to trade for breeding-stock? Did Embery know about northfinders? It seemed not; alas, though, Tempestamer carried only one, which wasn't in brood-phase this year. Besides, they seldom bred true, a problem that plagued the Hearthomer animal-breeders too.

...On the highest of the nearby hills, the one Embery had pointed to from the crown of the healing-house, her uncle Chard—older and fatter than his brother—complaining about the difficulty nowadays of studying the stars because the sky was cloudy so much more often than in his youth, and boasting about the knowledge of ice which he had acquired only a few days' journey from Hearthome. There was, apparently, a range of mountains whose peaks were snowcapped even in these latitudes, a fact which dismayed Wellearn, for if the mountains were closer to the sun, how could they be so much colder than the land below? Surrounded by telescopes which made Skilluck's look like a toy, Chard launched into a lengthy lecture concerning reflectivity and absorption, conduction and convection, aurorae and shooting stars and a score of other concepts which Wellearn failed to grasp but which filled him with tantalizing excitement: so much knowledge, so much to be found out!

...In a giant tree at the heart of the city, hollowed out deliberately and ornamented with the finest and handsomest secondary plants, a glass container sealed with wax, through which could be glimpsed the original of Jing's scripture. It was uncapped only once in a score of years, so that a fresh copy might be made, but even so it was starting to rot, and next time they planned to make two copies, of which one would be incised on rock instead of perishable wood. In any case, though, by this time the Hearthomers had added many new discoveries to those of Jing and Twig. Everything he was told fascinated Wellearn, and above all he was seized by the tales of the New Star which Chard and Shash and Embery recounted. And, over and over, he pondered the central teaching of Jing's followers: that the stars were fire, and one day the planets would go to feed them, as charcoal was added to a furnace, to make them blaze up anew.

"We do not believe," Embery told him soberly, "that we are here solely to endure until the world falls into a dying sun. We believe it is our duty to escape that fate. Out there are countless worlds; until the end of time, some will remain for us to live on."

"But how can one travel there?" was Wellearn's natural riposte.

"We don't know yet. We mean to find that out."

Everywhere he went Wellearn had a sense of being watched and weighed and scrutinized. Until the captain regained his health, he was the Wego's sole ambassador; he did his best to behave accordingly.

And the day after Skilluck took Tempestamer to sea and brought her back content with what she had engulfed in open water, he found out that his conduct had impressed the citizens. For Shash came to tell the strangers they were invited to a gathering of the general council, to discuss a mutually advantageous proposition.

"What they mean," was Skilluck's cynical comment, "is that they've figured out a way to rob us blind. Well, we have to go along with the deal; we have no choice."

Wellearn bit back his urge to contradict. Time would tell.

IV

"It grieves us all to learn of the death of our visitor Blestar," Chard said to the assembled council. The foreigners dipped in acknowledgment, although Strongrip and Sharprong were reluctant and only a glare from Skilluck compelled them. Wellearn was still recovering from the shock of having to conduct his first-ever funeral, and in a far-off land at that. But the ceremony had been decent and respectful, even though the Wego tradition of committal to the ocean was unknown here, so Blestar's corpse was fertilizing a stand of white shrubs.

Now it was his duty to interpret some of the most complex statements he had ever heard in any speech. Chard and Shash had given him a rough idea in advance; nonetheless...!

Still—he brightened—none of the others spoke Forbish, let alone this modern descendant of it, although he had the distinct impression that Skilluck often understood more than he let on.

At all events, he had the chance to trim the list of the debate. He was determined to do so. He wanted his people and the Hearthomers to be friends; he wanted, in particular, to spend the rest of his own life here ... not that he would dare risk admitting it. What he hoped was to be appointed resident agent for the Wego, and oversee a regular trade between north and south. So many benefits would flow from that!

But he must concentrate, not rhapsodize. The discussion was likely to be a long one. The Hearthomers took refuge from the hottest part of the day, but the assembly had gathered in late afternoon, and might well continue throughout the succeeding night. He composed his mind and relayed Chard's next remarks.

"We have been told that winters grow colder and longer in your land. Since according to our observations the sun is growing brighter and hotter, we are faced with a paradox."

("What in the world is he on about?" grunted Sharprong. "It doesn't make sense!")

But Wellearn was gripped by Chard's statement and anxiously awaiting what was to follow.

"We know this because we have carefully calibrated the way in which certain substances change after exposure to concentrated sunlight under identical conditions, that's to say, on a completely clear day. Cloudless days, of course, are growing fewer"—and several present glanced anxiously at the sky where yet more thunderheads were brewing—"but we keep up our experiments and we can be nineteen-twentieths sure of our conclusions."

("Is he ever going to come to a point?" was Strongrip's acid reaction.)

"We can only deduce that more solar heat causes more clouds to reflect it and more moisture to fall at the poles as snow, which in turn reflects still more light and heat. At my laboratory the possibility can be demonstrated using a burning-glass and a block of white rock half-covered with soot."

Wellearn had seen that demonstration; he had not wholly understood what he was meant to learn from it, but suddenly a blinding insight dawned on his mind.

("Come on, boy!" Skilluck rasped. "You're falling behind!")

"At a time when mountains here in the equatorial zone can remain snowcapped throughout the year, this is clearly a worrisome situation. Those among us who have never experienced ice and snow may doubt what I say, but I have felt how cold can numb the pads, seen how it affects the plants we here take for granted!"

("Why does he have to go on so?" growled Strongrip, but Skilluck silenced him with glare.)

"We must therefore anticipate a time when mariners from the far north will arrive, not driven hither by a fortunate storm, but because their home has become uninhabitable. Yet this need not be an unmitigated disaster. For if there is one thing we lack, then ... But I'll leave the rest to Burney."

("I've been told about him!" Wellearn whispered in high excitement. "He's the one-who-answers-questions, their most distinguished administrator! But I never saw him before!")

Burly, yet as tall as his compatriots, Burney expanded to full height as Chard lowered. He uttered a few platitudes about the visitors before picking up Chard's trail.

("I know his sort," Skilluck said contemptuously. "The politer they are, the more you need to brace yourself!")

"What we lack, and in lacking neglect our duty, is access to the oceans!" Burney stated at the top of his resonant voice. "Oh, we've done well by our founders in spreading their teaching across this continent; travel a moonlong overland and you won't find a child of talking age who doesn't grasp at least the rudiments of what Jing bequeathed! But we know there's more to the globe than merely land, don't we? Proof of the fact is that our visitors came to us from a country which can't be reached from here dry-padded!"

("You told them that?" Skilluck snapped at Wellearn. "Oh you threw away a keen prong there!")

("I did nothing of the sort!" Wellearn retorted, stung. "Listen and you'll find out!")

"Suppose, though, we were to combine the knowledge we've garnered with the skills of these strangers," Burney went on. "Suppose the brave seafarers of the Wego could voyage free from fear of cresh; suppose on every trip they carried the knowledge which Jing instructed us to share with everybody everywhere, so that every one of their briqs was equipped not just with a northfinder—I'm sure you've been told of their brilliant development of that creature which can always be relied on to point the same way? Though it does seem," he added with a touch of condescension, "they don't realize that if they really had crossed the equator, as Wellearn appears to imagine, it would reverse itself."

(Amid a ripple of knowing amusement Skilluck fumed, "It doesn't surprise me! After the flattery, the put-down!")

Burney quieted the crowd. "Perhaps that remark was unworthy," he resumed. "At all events, we know these are an adventurous people, who take the utmost care to ensure that when they set out on no matter how risky a voyage they can find their way home by one means or another. Suppose, as I was about to say, they carried not only telescopes useful for sighting a promising landfall, but better ones suitable for studying the sky, and the means to prove to anyone they contacted how right Jing was in what he wrote!"

(Applause ... but Wellearn had to cede a point to Skilluck when he mused, "So they want to overload our briqs with chaplains worse than Blestar?")

"We therefore offer an exchange!" Burney roared. "I hope Captain Skilluck will accept it! We will share with his folk everything we know— yes, everything!—if the Wego will put their fleet at our disposal every summer for a score of years, to return laden with southern foods and southern seeds and southern tools, after carrying our message to lands as yet unknown! Now this is a grand scheme"—his voice dropped—"and there are countless details to thrash out. But we must first know whether the principle is acceptable."

(Skilluck looked worried. Wellearn whispered, "They do things differently here!")

("That's obvious! He never tried to preside at a captains' meeting!")

"I see there are doubts," Burney said after a pause. "Let me add one thing, therefore. Assuming they accept our offer, then—if the winters at Ushere do become intolerable, as we may apparently fear according to what Chard has said—their people can remove hither and settle around the bay where their briq first made landfall. We would welcome them. Are we agreed?"

A roar of enthusiasm went up, and among those who shouted loudest Wellearn was proud to notice Embery. But Skilluck gave a brusque order.

"Tell him we need time to discuss this idea. Say we will be ready no sooner than tomorrow night!"

Perforce, Wellearn translated, and the assembly dispersed with many sighs.

"It's a trap," said Strongrip for the latest of a score of times. "There must be some snag in it we don't see!"

"I've been everywhere in the city and met many of the most prominent of these people!" Wellearn declared. "They take Jing's teaching seriously—they really do want to spread his knowledge around the globe!"

"That's what frightens me most," grunted Skilluck. "Blestar was bad enough; embriqing with a stranger who has absolute rule over what course I choose is out of the question!"

"That isn't what they have in mind!" Wellearn argued. "These people never travel the oceans—they want to hook on to someone who does, and that could be us!"

"Budlings!" Strongrip said, and turned away in disgust.

That was too much for Wellearn. Rising to his maximum height— which, since arriving here, imbibing vast quantities of creshban, and eating the best diet he had ever enjoyed, had noticeably increased—he blasted, "I invoke the judgment of my ancestors in the stars!"

And bared his mandibles, which normally he kept shrouded out of ordinary politeness.

Skilluck said hastily, "Now just a moment, boy—"

"Boy?" Wellearn cut in. "Boy? I haven't forgotten my oath of fealty to my captain, but if you can't recognize a man who's just become a man I'll consider it void!"

Following which he opened his claws to full extent, and waited, recklessly exuding combat-stink.

At long last Skilluck said heavily, "It was time, I guess. You're not a young'un anymore. But do you still want to challenge Strongrip?"

"I'd rather we were comrades. But I must. Unless he accepts me for what I am, with all my power of judgment. I did," Wellearn added, "invoke the honor of my ancestors."

There were still creshmarks on Strongrip's mantle, but Wellearn's was clear. Skilluck studied each of them in turn and said finally, "I forbid the challenge. Your ancestors, young man, are honored sufficiently by your willingness to utter it. Strongrip, deny what you last said."

He clenched his body into battle posture, mandibles exposed, and concluded, "Or it must be me, not Wellearn, you take on!"

The stench of aggression which had filled the air since Wellearn rose to overtop his opponent provoked reflexes beyond most people's control. Only someone as sober and weather-wise as Skilluck could master his response to it.

Strongrip said gruffly, "He speaks this foreign noise. I admit he knows things I can't."

"Well said, but is he adult, worthy to be our comrade?"

The answer was grumpy and belated, but it came: "I guess so!"

"Then lock claws!"

And evening breeze carried the combat-stink away.

"Captain!" Wellearn whispered as the general council of the Hearthomers reassembled.

"Yes?"

"Did you know I was going to be driven to challenge—?"

"Silence, or I'll call you 'boy' again!" But Skilluck was curling with amusement even as he uttered the harsh words. "You haven't finished growing up, you know!"

"I'm doing my best!"

"I noticed. That's why I didn't let Strongrip shred your mantle. He could have, creshmarks or no! So you just bear in mind your talent is for reasoning, not fighting. Leave that sort of thing to us seafarers, because at pith you're a landlubber, aren't you?"

"I—I suppose I am," Wellearn confessed.

"Very well, then. We understand each other. Now translate this. It's exactly what Burney most wants to hear. Begin: 'We can't of course speak for all the briq-captains of the Wego, but we will promote with maximum goodwill the advantages of the agreement you suggest, provided that at the end of summer we may take home with us tokens of what benefits may accrue therefrom, such as creshban, better cleanlickers, useful food-seeds, spyglasses and so on. Next spring we'll return with our captains' joint verdict. In the event that it's favorable'—don't look so smug or I'll pray the stars to curse you for being smarter than I thought but not half as smart as you think you are!—'we shall appoint Wellearn to reside here as our agent and spokesman. Thank you!'"

V

At every summer's end the Wego captains came together for a bragmeet where the wise'uns too old to put to sea might judge whose briq had ventured furthest, who fetched the finest load of fish ashore, who brought the rarest newest goods traded with chance-met strangers. It was the high point not only of their year, but the chaplains' also. For generations the latter's influence had been shrinking, particularly since too many stars fell from the sky for most people to look forward to inhabiting one after death. But when it came to matters of ancient tradition, naturally they were called on to preside.

This meet, though, was different. Now there was no boasting, only mourning. On land things had been bad enough, what with crop-failure, floods and landslips, but at sea they were infinitely worse. Braverrant had not returned albeit her master was Boldare, wily in weather-ways. No more had Governature with Gallantrue and Drymantle, nor—next most envied after Tempestamer—Stormock, whose commander had been Cleverule, sole among them to make two-score voyages.

Nor Wavictor, nor Knowater, nor Billowise ... and even Tempestamer herself had not reported back.

Yet weather-sense warned them: the summer was done. The customary congress must convene.

Frost on every tree, snow on the beach above the tide-line, even icefloes—but it was too soon! As Tempestamer closed the last day's gap between her and the waters where she had been broken, uncertainly as though aware something was amiss, Wellearn gazed in horror at the shoreline through drifting mist.

"Captain!" he cried. "Have you ever seen so much ice at this season, or so much fog?"

"Never," answered Skilluck sternly. "Maybe what your friends at Hearthome spoke of is coming true."

"I thought—our friends...?"

"Those who have knowledge sometimes batten on it to gain power," Skilluck said.

"They spoke of partnership, not mastery!"

"What difference, when we are weak and they are strong? Count me the briqs you see at Ushere wharf and argue then!"

Indeed, the fleet numbered half its usual total, and the houses were white with rime and some were tilted owing to landslips, and the sky was dense and gray and the wind bit chill into the inmost tubules of those who lately had enjoyed the warmth of Hearthome.

"What's more, there's nobody to welcome us!" Skilluck blasted, having surveyed the city with his spyglass. "They must have called the bragmeet, giving us up for lost!"

Seizing his goad, he forced Tempestamer to give of her utmost on the final stretch towards her mooring.

Shivering in the branchways, more of the Wego attended the bragmeet than ever in history, and while the wise'uns tried to present the summer's achievements in a flattering light, kept interrupting to ask, "What use is that to us? Can we eat it? Does it help to keep us warm?"

In vain the senior chaplain, by name Knowelkin, strove to maintain formality. The folk mocked the claims of those who had survived the unprecedented summer storms by staying close to home, like Senshower whose Riskall had belied her name by scurrying from inlet to sheltered inlet, like Conqueright who had pledged the reputation of his Catchordes on the chance of garnering vast quantities of fish only to find the schools weren't running where they did. Almost as though they were hungry for news of doom the assembly listened in silence to Toughide and Shrewdesign, who told of icebergs sighted all season long further south than ever known before, fisherfolk driven into mid-ocean clinging to barqs unfit for any but fresh-water work, great trees torn loose by gales and set to drifting with the current, some bearing signs of habitation as though they had formed part of a house, a town or even a city. And when eventually they did make landfall, they reported, they found long tracts of coast abandoned to the dirq and fosq, the icefaw and snowbelong, whose normal range was half-a-score days' journey poleward.

"What we brought home from our voyage," Toughide concluded soberly, "was no better than what we'd have got had we made due north."

The company shifted uneasily, but the chaplains preened. Now the meeting had settled down, they could remind themselves how hunger and anxiety invariably drove folk back to the faith and customs of their ancestors.

But suddenly a roar cut through the soughing of icy wind among the boughs.

"Who dared to summon a bragmeet without Skilluck? What misbudded moron told you Tempestamer would not ride out the worst of storms? Let him stand forth who called the meet before I came!"

And the furious captain stomped into the center of the gathering, healthy-tall—taller than any Wego mariner in living memory—followed by Strongrip and Sharprong and someone whom the company had difficulty in recognizing: Wellearn. But a Wellearn transformed, bigger, huskier, and infinitely more self-confident than the callow youth who had set forth in spring.

Knowelkin shrank reflexively at Skilluck's intrusion, all the more because he and his companions were so obviously in good fettle. The captain fixed him with a glare.

"You!" he said accusingly. "You took it on yourself to say I must be given up for lost!"

"Not I!" the chaplain babbled, casting around for a way of escape, for combat-stink from Skilluck filled the air and he was weakened by fasting.

"Liar!" hurled Toughide. "You insisted on the meet being held when we captains said to wait a while! You understand the calendar—you know the normal end of summer!"

"But summer this year ended early! Surely a skilled seafarer—"

"We've been in latitudes where there is no winter!" Wellearn shouted.

"That's right!" Skilluck set himself back on his pads, claws poised. "Nor any hunger, either! Look at us! Think we're sick—weak—crazy— dreamlost? See any creshmarks on us? But I see one on you!" Reaching out quicker than Knowelkin could dodge, he nipped the chaplain's mantle and provoked a squeal of pain.

"Thought so," the captain said with satisfaction. "Always the way, isn't it? When things get hard, instead of reasoning and working, you prefer to retreat into dreamness! Strongrip, make him drink a dose of creshban and see sense!"

"Best thing any briq from Ushere ever carried home," the seaman grunted, holding aloft a Hearthomer nutshell. "A certain remedy for cresh!"

That provoked a stir of excitement among the crowd.

"But," Strongrip continued, "do you think we should waste it on this idiot? After all, he's been starving himself like Blestar—deliberately— and Blestar was the only one of us it didn't save!"

"That's a point," said Skilluck ruminatively. "Very well, let them be the ones to go without. It'd be a fit punishment for the way they've insulted us."

"You have a cure for cresh?" Knowelkin whispered, voicing what all present wanted to hear.

"Not we, but allies that we've made in the far south. They've offered us as much as we need—they have plenty!—in return for letting some of their wise'uns travel on our briqs to spread their knowledge. And don't think creshban is the only trick they have under their mantles! Oh no! We've brought back marvels which ... But move over, you! Senior chaplain or not, you're a dreamsick fool and it's your own fault and Wellearn is worth a score like you! Move, before I rip your mantle into tatters!"

For an instant it seemed that Knowelkin would defy the captain out of pride; then he humbly crumpled to half normal height and padded aside. Wellearn found himself at a loss. Was he really meant to take over and preside at a bragmeet, youth that he was?

"Well, go on!" Skilluck rasped. "Or I'll start thinking you're as silly as Knowelkin! Speak out!"

"What shall I tell them?"

"Everything! Everything! I never imagined things would come to so grievous a pass this year. Next year maybe, or the year after ... but it's upon us, and the land is in the claw of ice, and if another summer comes it could be our last chance to move to friendly country. The briqs which survive may already not be enough to shift us all! Hadn't you thought of that?"

Wellearn hadn't, but he pretended, and gave a grave nod of acquiescence as he took over the spot vacated by Knowelkin. After so long among the Hearthomers he felt like a giant compared to his own people ... as tall as Jing!

And that gave him his opening. Maintaining his maximum height, trying to imitate in Wegan the style and manner of Burney and others who addressed council meetings at Hearthome, he began.

"Teachers like Knowelkin—and even my late mentor Blestar who has gone, let's hope, to make a star shine brighter!—told us to believe there never was a real person called Jing! They've encouraged us to be obedient and small-minded by saying there never was a man who understood the stars and made their nature manifest by transforming dull rock into marvelous new substances! With the evidence of spyglasses and metal blades to contradict it, we chose to accept this nonsense!

"But we have met followers of Jing who actually possess his scriptures, and I've read them and copied extracts for our use! Thanks to what Jing taught, the city of Hearthome is the richest on its continent! By studying Jing's principles the folk there have arrived at creshban and other medicines—they've bred mounts that go on land as our briqs swim the sea" (thank you, Embery! he added silently) "—they live in houses which make ours look like hovels—they have such wealth that a bunch of sick seafarers stranded there by accident might each repose in his own bower, recovering with the aid of a cure their own folk might not need in fivescore years of which they yet keep stock for chance-come travelers..."

Gradually, as he talked, Wellearn let himself be taken over by imagination, such that in his present state of vitality it would not shade into mere dreamness. He painted a picture of a glorious future to grow from the joint seed of the Hearthomers and the Wego. Some of his audience, he noted with dismay, had ceased to listen the moment he spoke of Jing as a real person; others, however, less parched by cold and shrunken by privation, were clinging with their remaining strength to wisps of hope.

Concentrating on the latter, he concluded with a splendid peroration that sent echoes ringing among the rigid branches and ice-stiffened foliage.

Yet only a few of his hearers clacked their claws, and after a pause Toughide said, "So you're asking us to pile aboard our remaining briqs and set forth now?"

"Of course not!" Skilluck roared. "But next year could see our last and only chance to move to a warm and welcoming land! If you won't hark to the boy—excuse me, Wellearn!—if you won't hark to the young man, then trust in me who came home after Knowelkin told you I was dead!"

For a moment Wellearn thought his forcefulness had won the crowd over, but the idea of quitting the land where the Wego had lived since time immemorial was too great to be digested all at once, and the assembly dispersed without reaching a decision. Vastly disappointed, Wellearn slumped to four-fifths height while watching them depart.

"Excellently done," said Skilluck softly at his side.

"I thought I'd failed!" Wellearn countered. "At any rate I don't see them clustering around us to vote Tempestamer the wise'uns' prize for the past summer!"

"Oh—prizes!" Skilluck said contemptuously. "To be remembered in a score-of-score years: that's something else. Until I saw how few briqs had made it back to Ushere, all I could think of was how the Hearthomers might cheat us. Now I've felt in my tubules how right they are about the grip of ice. It's time for a heroic gesture, and since someone's got to make one, it might as well be us. If we can get enough of the folk to emigrate next spring, one day they'll talk of us as we do of Jing. I felt this as truth. I couldn't have expressed it. You did. That's why I say you made a great success of it."

"Captain," Wellearn muttered, "I never respected anything so much before as your present honesty. I'm glad to find I guessed right after all but what you've just said—"

"Save it," Skilluck broke in. "And don't worry about persuading the rest of the folk around to our course. A few score days of cold and hunger will take care of that."

"I wish I could share your optimism," Wellearn sighed. "Yet I greatly fear that some of those who refused to listen did so not because they suspected us of lying, but because misery has already taken them past the reach of reason."

VI

"Uncle," Embery said musingly to Chard, "do you think Wellearn will come back?"

Grousing at the annual need to adjust the mountings of his telescopes because the branches they rested on had swollen in the rainy season, her fat and fussy uncle finally pronounced himself satisfied with the work of his apprentices. Since it was again too cloudy at the zenith for serious star-study, he ordered the instruments to be trained on the skyline.

"Hush, girl," he said absently. "In a little I can show you moon-rise like you never saw it before."

"But do you?" Embery persisted.

"With all the joint advantages that will flow from our alliance with his folk, why not?"

"Father says he doesn't think the captain trusted us."

"Just as long as that briq carried them home safely—and who's to say she couldn't if she lived out the awful storm which drove her here?—then you may rely on the powers of persuasion displayed by your young friend to bring more of their fleet here, and, if nothing else, the captain's greed ... Ah, thank you!"—to the senior apprentice for advising him that the first telescope was properly set. "Now, my dear, come here. Before moon-rise, because this direction is fairly clear, I'd like to show you what they used to call the New Star. Ever since, more than a score-of-score years ago—"

Embery stamped her pad. "Uncle, I'm not some ignorant youngling from the city school, you know!"

He blinked at her. "No need to be offensive, niece! Of course I know you've looked at it before, but I want to share a new discovery with you, and I don't believe you've understood half the implications of what I've tried to teach you."

"I have so!"

"Then tell me how the world can grow cooler even though the sun seems to be getting warmer—and I've worked out why!"

"For the same reason it's better in full sunlight to have a light mantle than a dark one! Reflection!"

But Embery's mood changed even before he could compliment her on a lesson well remembered, and she said, "You think you've worked out why? You never told me that! Go on!"

And she cuddled up alongside him much as she used to do when she was barely strong enough to stand upright, so that he had to lift her to the ocular of his telescopes.

Chuckling, Chard said, "That's more like my Baby Rainbow! I used to call you that, you know, until you took offense and said it was ridiculous to use the name of Jing's lady—"

"I still think so!" she interrupted. "Come to the sharp end of the prong!"

"Very well." Chard settled back comfortably. "My line of reasoning goes this way. We have seen, in the place of the so-called New Star, nothing but a cloud of bright gas for many generations. Yet every now and then we have recorded a sort of wave passing through it, and comparison of notes made recently with those made just after the first proper telescopes were constructed allows us to hypothesize that the sudden addition of a large amount of new fuel to the fire of a star causes an outburst of colossal proportions, as when one drops a boulder into shallow water. There are splashes!"

"You've told me this before!" Embery complained.

"Ah—but what about the matter that gets splashed?"

She thought about that for a little. Eventually she said, frowning with concentration, "It must spread out, over huge distances. And it must get thinner as it goes."

"Correct! Even so...?"

"Even so, when it reaches another star—Oh!" She stared upright in excitement. "You think a splash from the New Star has got this far?"

"It would explain a lot of things," Chard murmured, looking smugger than an astronomer of his age and distinction had any right to. "Above all, it would explain very well indeed why there are more and more stars falling from heaven—which of course aren't actually stars—at the same time as the sun is growing warmer."

"But this could be terrible!" Embery exclaimed. "Because the matter must have spread out very thin on its way here, so if it's only the first bit that's got to us, then—"

"There may be more to come," Chard confirmed. "And we have no way of telling whether there will be so much that it screens out sunlight, or enough to heat up the sun so that ice will melt again, or as much as we've had already with nothing to follow. Whatever happens, though, the Wego are due for the most appalling trouble. So could we be if the ice melted after forming, all at once. We'd need their help to rescue us if the level of the sea rose. Who knows how much water has already been frozen up? But we keep hearing from the fisherfolk that they have to go further and further every year to cast their nets deep ... Oh, every way it makes sense to ally ourselves with the Wego! Whether they agree is another matter. I mean, they may be as ignorant of the effects of a polar melting as most of our own folk are of the effects of freezing! When I climbed the Snowcap Range..."

Embery sighed. Her uncle was about to launch into one of his self-congratulatory reminiscences. There was no hope of hearing more, as yet, about his new theory, so it would be best to distract him.

"Isn't it time for me to look through the telescope?" she offered.

"Of course! Of course! And I want you particularly to take note of—"

He bustled about, issuing orders to the apprentices, but they were superfluous; all her life, Embery had been accustomed to sighting and using a telescope. She applied her eye.

And tensed. The tropical night had not yet fallen; the sun, behind a patch of western cloud, still turned the sky to blue. In a few moments it would vanish, but for the time being its rays slanted across the ocean.

"That's not the New Star rising, or the moon either!" she exclaimed.

"Patience, my dear!" said Chard indulgently. "Wait for nightfall. Then, just above the horizon—"

"Not above! On!"

"Are you sure?"

"Oh, don't be so silly! Look, quickly!"

Sliding aside, she almost dragged him into position behind the eyepiece.

After a long pause he said, "My dear, I owe you an apology."

Upside-down in his field of vision was something like a giant fang, neither white nor blue nor green but a shade between all three.

"I wish them well in the far north," he muttered. "That's all I can say."

"Why?" Embery was almost crying.

"I never saw one before, but I recognize it from the descriptions I've read and heard." Chard glanced at his niece. "I think you must have done the same."

"Yes, but I was so much hoping you would say I'm wrong!" Embery clenched her claws. "Is it—"

"I'm very much afraid it must be. Further south than anybody has ever met one: that's an iceberg."

"You mocked me publicly before the folk!" charged Knowelkin.

A sky full of racing black clouds leaned over Ushere; a bitter gale lashed the wharf, the harbor; snow turning to hail battered land and water like a forestful of spongids uttering their pellets of spawn in an evil season. Behind him ranged the muster of surviving chaplains: those who sacrificed bulk to tallness, who had been infuriated when Skilluck and his companions overtopped them. And all of them were exuding combat-stink of such loathsomeness that even the frigid blast of the wind did not suffice to protect those nearby.

What could protect anybody in the clutch of this terrible winter, when not even seaqs or dugonqs were to be trapped beneath the ice because there were no floes thin enough to stab through, when icefaws and snowbelongs rampaged into the middle of Ushere?

The chaplains said: the stars. But nobody had seen a star in four-score days...

Somewhat reduced from the great height they had attained at Hearthome, Skilluck and his comrades confronted them. The crew were at the wharf perforce, for Tempestamer had to be taken to sea once in a while to eat, there being no pickled weed or fish to spare from feeding folk. To the surprise and satisfaction of his captain, Wellearn too had volunteered to turn out, regarding himself now as a full member of the company.

More than one briq was unlikely to live until spring, being already too weak to face open water thanks to the neglect of her captain, but Tempestamer remained fat and energetic, and they meant to ensure she stayed that way.

"Who did the insulting?" Skilluck rumbled, rising to the bait. "Who declared that Tempestamer was too weak to swim through storms? Who said I was too bad a navigator to find a way home?"

"Who said we were crazy to trust to visions sent by the stars?" Knowelkin countered. "Who brought a benefit for all the folk and now is keeping it himself?"

"We're doling out our creshban to those most in need!" roared Sharprong, clenching into fighting posture. "Those who have nothing to offer the folk may mock—like you!—and we shan't care!"

"Scores will! Scores-of-scores! You're traitors to the Wego!" Knowelkin shrieked.

Standing a little apart, Wellearn suddenly realized what made the chaplains' stink so harsh: fanaticism. They were so far into the maw of dreamness, reason would not convince them. And already they had deranged Skilluck, normally so self-controlled...

"Captain!" he shouted. "They've taken the windward of us! Shift round—shift round or they will make us mad!"

Startled, Skilluck shook himself as though emerging on land after a swim. "You're right, by Jing!" he exclaimed. "Sharprong! Strongrip! Quickly! Follow Wellearn!"

And with short but menacing strides they marched into the snap of the gale before turning and confronting the chaplains anew.

That put a very different color on the mantle of the situation. The exudate of righteous anger was accessible to those not breathing their own wafts of madness. It made the chaplains think again.

"How fragile is our sanity!" Wellearn whispered, not meaning anyone to hear.

"Once more you're ahead of the rest of us," Skilluck muttered. "But most of them are well and truly dreamlost!"

"Dreamlost?" Wellearn cried, straining to make himself heard against the howling of the wind. "No! They're frightened! And I'll tell you why! It's because if we steer the only sensible course and remove to Hearthome, they'll meet people who can contradict their lies about Jing!"

Skilluck clutched at his mantle. "If you provoke them any more—"

"They outnumber us," Wellearn returned softly. "Surely our best hope is to make them quarrel among themselves?"

Skilluck's eye widened. "Neat!" he approved, and went on at the top of his voice.

"That's right! Now suppose instead of Knowelkin, someone like you, Lovirtue, or you, Grandirection, had been in charge of the bragmeet: you'd not have insulted me, would you? You wouldn't be so afraid of meeting strangers, either, I'm sure!"

"Of course not!" they both exclaimed.

"Nonsense!" Knowelkin roared, turning on them. It very probably was nonsense, but all their tempers were set to snap like saplings in the path of a gigant.

Grandirection, whom Skilluck had picked on because he was visibly near breaking-point, immediately raised his claws and bared his mandibles and began to pad around Knowelkin seeking an opening for attack. In the meantime, several people had emerged from nearby houses and were gazing in wide-eyed astonishment at these chaplains making ready to disgrace their calling.

"Now's our chance," Skilluck whispered. "And—and thank you, Wellearn! Much more of this, and I'll come to think you are as smart as you imagine!"

A few moments later, the crew were able to pry Tempestamer's cold-stiff tentacles free of their mooring and goad her towards open water. Such was the violence of the wind, she was already tossing before she quit the harbor-mouth.

"What a disgusting spectacle that was!" shouted Wellearn against the blast.

"There's nothing wrong with them that a mawful of decent food wouldn't cure," Skilluck replied. "If only more of the Hearthomer seeds had taken...!"

"How could they," Wellearn sighed, "in a year when even the pumptrees are chill?"

They stood in a grove at the center of Ushere; it had been because of them that the Wego made their original decision to settle here, rather than the harbor, which was like half a score others nearby. Their taproots were known to reach an underwater spring, far below the level where a storm could stir the sea, which brought heat from deep-lying rocks. Carefully pierced and plugged, they furnished a year-round supply of warm fresh water. It was said that in the old days the chaplains denied that heat could come from any source except the sun, holding the stars to be cool because the spirits of the righteous dead departed thither after separating from the unrighteous in the moon—whose phases showed the division taking place—and that it had been the start of their decline when brave divers wearing capsutes under their mantles for a store of air reported that the sea-bed was warmer than the surface at this spot ... a fact for which they had no explanation.

Accordingly the seeds and spawn from Hearthome, all of secondary and parasitic or symbiotic plants, had been carefully planted in crevices of pumptree bark, not because that was the species most resembling their usual hosts but because they were the only trees likely to remain sapswollen.

However, the diet didn't suit the strangers; some died off completely, some seemed to be lying dormant, and of those which had sprouted, none yielded the harvest that could be relied on at Hearthome.

Still, any extra nourishment was welcome...

Already, though, as the chaplains bore witness, voices were being raised against Skilluck and his crew, blaming them for what was not in their control: bringing the wrong sort of seeds, not insisting on being given more creshban, wasting space on spyglasses and articles of metal instead of food. It would be hard to keep their tempers in face of such taunting. Nonetheless it must be done. No other plan made sense than removal to Hearthome; no briq but Tempestamer could lead the fleet thither. There were no charts for her storm-distorted course.

So she must be fit and lively four-score days from now. Or they were doomed.

VII

For a while longer the fact that Skilluck and his comrades—surviving on what they had stored during their season of good eating but otherwise, save mentally, in little better shape than anyone else—struggled along the frost-rimed branchways to deliver doses of creshban, together with what scraps of fruit or leaf or funqi-pulp their exotic plantings on the pumptrees yielded, counted heavily in their favor, while the chaplains, who had disgraced themselves by their affray on the wharf, lost countenance.

Then the creshban started to run out, while the number of victims multiplied, and even some who had declared support for the idea of emigration took to accusing Skilluck of lavishing the medicine on himself at others' expense. By that stage it was useless to argue. People were taking leave of rationality and slumping into stupor from which a few at least would never revive.

The sole consolation was that, undernourished and sickly as they were, none of the Wego any longer had the energy for fighting. But that meant, of course, they would have none to prepare for a mass exodus when the weather broke, either.

"Why did we come home?" Wellearn mourned more than once. But Skilluck strictly reprimanded him.

"We had no way of knowing how bad this winter was to be! Nor would we have felt easy in our minds had we abandoned our folk to face it without help!"

"At least we needn't have found out until next summer," Sharprong grumbled.

"By which time our kindred and our young'uns could have been dead! As things are, we stand some slender hope of keeping a clawful of the folk alive."

"Slender..." Strongrip muttered, gazing at the drifts which blizzard after day-long blizzard had piled against the bravetrees. Many upper branches and almost all their fronds had frozen so hard the wind could snap them off, and every gust was greeted with their brittle tinkling.

"Next time we take Tempestamer to sea we'll hang a net while she feeds," Skilluck sighed. "Even a load of sour weed could save another briq or two."

"Captain, you can't keep our fleet in being singleclawed!" Strongrip began. Skilluck silenced him with a glare.

"Name me another captain who's fit enough to help?"

There was a dismal pause. At length Wellearn ventured, "Maybe Toughide?"

"One might well try him, sure. Wait on him and ask if he will join us. If he won't, I'll still do what I can to feed his briq, or anyone's!" Skilluck stamped his pad. "How many summers to catch and pith and train the briqs we need to replace Stormock and Billowise and the rest? For all we know, there may not be another summer!"

So it was done, and Toughide goaded his weak and weary Watereign forth in Tempestamer's wake the next clear day, and though she was less elegantly pithed, a lucky mawful of fish revived her and he was able to make it back to shore with a mass of weed caught on curved prongs, lacking nets such as Skilluck had preserved.

When it was noised abroad that those briqs too feeble to risk the winter ocean were nonetheless receiving fodder, a few score folk made their way to the wharf and watched the spectacle in silence. It was unprecedented. Never in history had any captain of the Wego acted to aid his rivals; rather, he should frustrate them so they would not win the wise'uns' prize.

It was a new strange thing. The onlookers dispersed and reported it. Next time the weather cleared not two but seven briqs put out: Riskall came, and Catchordes, and Shrewdesign's Neverest, and two more so young their captains had not named them, which seemed barely strong enough to quit the harbor.

Towards these last Tempestamer behaved most strangely, for she slowed her pace instead of exulting in the water, and kept them in her lee as though they were of her own budding. By now Wellearn was informed concerning the manner of pithing and breaking a briq, and therefore he exclaimed in amazement.

"Captain, had I known when I first joined your crew that you'd left Tempestamer with those nerves intact...!"

He left the rest unsaid. There was no need to explain he meant the nerves governing a briq's response to briqlings. It was generally held to be a recipe for disaster to do as Skilluck had done, for such a briq might fall in with a wild herd and become ungovernable.

Dryly Skilluck made reply, "Most likely my Tempestamer would cut younglings out of the herd without orders and drive them home with her! It's something I've always wanted to try. Is she not huger, even now, than any wild'un?"

It was true. There was no record, not even any legend, of a briq's surpassing her, and she was still growing despite the dreadful winter.

"We'll find a wild herd off the coast near Hearthome," said Skilluck dreamily. "We'll let her pick the young'uns she personally likes. We'll raise such a fleet as will conquer any ocean, any season. Before my time expires, I hope to see the Wego travel round the globe!"

"Captain!" said Strongrip with a sharp reproof. "We have to live until the summer first!"

"Agreed, agreed," the captain sighed, and raised his spyglass to search for weed among the random floes.

They returned with not only weed but plumpfish, for Tempestamer sensed a school of them and patiently circled until they had to approach the surface again where she and her companions could feed and nets haul up what was left. The other captains were loud in admiration, and Skilluck seized his chance to exact a pledge: were spring to be delayed, were the fields to lie under frost a moonlong past usual, they would take aboard whomever of the Wego wished to come and head south, following Tempestamer.

Hearing the vow taken, Wellearn almost collapsed from relief.

"Captain, we're saved!" he whispered.

"Didn't I tell you? A few score days of hunger and cold, and then a mawful of good food ... But we aren't on course yet. So many of us are too lost in dreamness to work out what's best for our salvation."

For at least a while, though, it seemed Welleam's prediction was assured of fulfillment. Revived by the gift of fish, half the Wego came to watch the next departure of the fleet—and help carve up the carcass of a briq that had died at her moorings, a tragedy for her captain but valuable food to the folk—and among them were Knowelkin and Grandirection, who had composed their quarrel. They made shift to chant a star-blessing on the departing briqs, and the crowd settled into familiar responses even though a few budlings, too young to have seen a clear sky, were heard to ask fretfully what stars might be.

Two calm days followed, and the nets were quickly filled, suggesting that warm water was working up from the south in earnest of springtime and bringing bounty with it.

But on the fleet's last night before returning home a fiery prong stabbed out of heaven and exploded on a berg, raising a wall of water high enough to swamp the smallest briq. There was a thunderclap, followed by a cascade of ice-chips, but this was not hail and that had not been lightning.

Tempestamer gave forth a cry such as no tame briq had ever been heard to utter, and for hours ran out of control, seeking the lost young'un. Although Skilluck finally mastered her again, and set course for Ushere well before dawn, it was obvious that some captains were regretting their pledge. After all, if despite the chaplains' blessing the sky signaled its enmity, what hope was there of carrying out Skilluck's plan?

"That was an omen!" was his retort. "If we don't move south, that's what we can look forward to more of! Wellearn, do the skies hurl such missiles at Hearthome?"

"Not that I was ever told!" Wellearn asserted.

"But you said the stars look down on Hearthome more than us! Maybe we should stay here, cowering under cloud!"

Wellearn was taken aback until he saw what Skilluck was steering towards. Then he roared, "Safe? Did that prong strike from clear air? More likely the stars are warning us to move where we can see them and be seen, instead of hiding from them all the tune!" The force of his logic told to some extent, but what counted most was that their weather-sense had given no warning of that blow from heaven. Had it been a lightning-strike, it would have been preceded by a sense of uncomfortable tightness and uncertainty. As things were, the discomfort had succeeded the impact. The sensation was weirdly disturbing.

Shortly thereafter the chaplains, whose duties included keeping track of the calendar, marked the usual date of spring. Weather-sense contradicted that, too. Traces of a thaw did occur; many beaches were cleared of ice as warm water washed against them. But uplands to the north which ordinarily caught the early sun-heat remained capped with snow, and even in low-lying valleys there were places where the drifts endured. As for the ground where new crops should be planted, it was stiff as stone a moonlong later.

"I hold you to your vow," Skilluck said when that day dawned, and the other captains shuffled their pads noisily. "But for me, would your briqs be even as healthy as they are?"

"Ask the storm-lost," someone muttered.

"They're not here—we are!" Skilluck snapped. "So are what's left of the Wego. Must they stay and starve because the bravetrees are frosted and nothing grows on them, because the fields are hard as rock and all seeds die at the sowing?"

"To risk cresh on a crazy course to nowhere?" another cried.

"To suffer cresh right here, when creshban is to be had at Hearthome and Tempestamer can guide us thither?" Wellearn countered.

Of all the various arguments advanced, that struck deepest in his listeners' tubules. Even those who had best planned to cope with the winter were showing creshmarks now, and saw little hope of escape before the sickness claimed their powers of reason.

"We'll follow you," said Toughide finally. "With all the family and friends our briqs can carry. And let those who choose the other way be cast upon the mercy of the stars."

"Then get to work!" Skilluck rose to what was left of his former height, and despite his shrunken mantle still overtopped the rest. "Tomorrow's dawn will see the Ushere fleet at sea, and our landfall will be in a kind and gracious country where we shall be helped by allies—helped by friends!"

"Uncle!" Embery cried, rushing up the slope that led to Chard's observatory. "Uncle, great news!"

Worried, absent-minded, owing to old age and the problems of the past few months which had so much interfered with his study of the stars, the old man nonetheless had time to spare for his brother's daughter. He beamed on her indulgently.

"Good news is always welcome! What have you to tell me?"

"Strangers are coming over the northern hills! It must be Wellearn's people at last! Did you not calculate that their spring must have begun by now?"

"Yes, at least a moonlong ago!" Suddenly as enthused as she was, Chard ordered one of his telescopes trained on the high ground to the north, and exercised an old man's privilege by taking first turn at its ocular.

And then he slumped. He said in a voice that struck winter-chill, "My dear, were you not expecting the Wego to arrive by sea?"

"Well, sure! But given how many of them there are, perhaps they had to ferry their folk to the nearest landfall and..."

She could hear as she spoke how hollow her words rang.

"This is no question of perhaps," her uncle said. "This is a fact. The fireworkers' district is being attacked. If that's the Wego's doing, neither you nor I want any truck with them!"

VIII

Heavier-laden than ever before, yet seeming utterly tireless, and with her back sprouting trencher-plants and vines as luxuriant as though this were an ordinary summer voyage, Tempestamer beat steadily southward on the trail which only a briq could follow through the currents of the ocean. Some said it was a question of smell; some, a matter of warmer or colder water; others yet, that briqs could memorize the pattern of the stars though they were invisible by day or cloud-covered at night. After all, maintained these last, a northfinder could be carried anywhere, even in darkness, and always turn the same unfailing way.

But most were content to accept a mystery and exploit it.

Certainly Tempestamer had learned from last year's storm. Now, if clouds gathered threateningly, she altered course and skirted them without Skilluck needing to use his goad, or when it was unavoidable hove to and showed her companions the way of it, even to locating masses of weed shaken loose by gales from coastal shallows. This gave much food for thought to both Skilluck and Wellearn, who served this trip in guise of chaplain because the passengers they had aboard would not have set forth without one. The former wondered, "Perhaps one shouldn't pith a briq at all. Perhaps there's a way of taming them intact. Could we be partners?"

While Wellearn mused, "The directions she chooses when she meets a storm: they imply something, as though the storm may have a pattern. At Hearthome I must study the globe that Chard offered to explain to me, because watching the sky..."

The other captains, though, grew afraid on learning how much of Tempestamer's weather-sense had been left intact. All of them had had the frustrating experience of trying to drive a briq direct for home when bad weather lay across her path, but rations had run so low that only a desperate charge in a straight line would serve the purpose of survival.

So too had Skilluck, as he said, and he preferred to come home late with vines and trencher-plants intact. What then of last year?—countered the others, and he could give no answer, except to say the fortune of the stars must have been shining on him.

Knowing him for a skeptic, they dismissed that and went on worrying.

Still, the weather continued fair. Despite the fact that they had met icebergs further south than even Toughide and Shrewdesign last summer, there had been whole long cloud-free days and nights, and the children had exclaimed in wonder at the marvels thereby revealed, especially the great arc of heaven composed of such a multitude of stars it never dwindled regardless of how many fell away in long bright streaks. Those riding Tempestamer kept begging for a peek through Skilluck's spyglass, and Wellearn amused them with fantasies based on something Embery had said, about the time when folk would travel to not just another continent, but another world.

One, though, acuter than the rest, demanded seriously, "Where do we find the kind of briq that swims thither?"

"If we can't find one," Wellearn answered confidently, "then we'll have to breed one—won't we?"

"She's slowing," Skilluck murmured. "That means landfall, if I'm any judge." Keeping his spyglass trained on the horizon, he swung it from side to side.

And checked.

"Wellearn, did the Hearthomers mention a people around here who consign their dead to the sea?"

Startled, Wellearn said, "That's a custom of seafaring folk like us! They said there were none on this whole coast! That's why when Blestar died we—"

"Oh, I remember," Skilluck interrupted. "But there are bodies floating towards us. Five of them."

It was in Wellearn's mind to ask whether he was mistaking some unfamiliar sea-creature, when his own eye spotted the first of them. No chance of error. Here came five light-mantled people of the Hearthome stock, and none was making the least attempt to swim...

"Stop Tempestamer eating them at all costs!" Skilluck roared to Strongrip. "It could be one of them is still alive!"

His guess was right. The last they hauled out of the water, while the passengers gazed in awe and terror, was still able to speak, though salt-perished and on the verge of death. Wellearn's mantle crumpled as he translated.

"We thought they were your people!" the stranger husked. "Even though they came to us by land! We thought maybe you were short of briqs to carry everyone..."He retched and choked up salt water.

"Go on!" Skilluck urged, aware how all the other captains were closing their briqs with his to find out what was wrong. Wellearn continued his translation.

"Beyond the mountains, land won't thaw this year! Except along the coasts, snow is still lying and the ground is hard as rock! That's what we found out from a prisoner we took. Never expecting an attack, we met the strangers with courtesy, but they were dreamlost and frantic and wrecked half of Hearthome before we managed to stop them. I never thought to see such slaughter, but they had started to eat us—yes, eat us!" A sound between a moan and a laugh. "And some of them were worse! They tried to eat themselves!"

"What of Hearthome now?" Wellearn cried, clenching his claws.

"I—we..."

The effort was too much. Salt-weakened, one of his lower tubules ruptured, and the victim saved from the sea leaked out his life on Tempestamer's back.

After a long dread pause Skilluck straightened. He said grayly, "We must go on. We can't go back. From what he said it's clear that if Ushere isn't doomed already it will be by next year. We've come south across a fifth of the world, and if even here we find that people have been driven off their lands by cold and hunger..."

There was no need to finish the statement. Those around him nodded grave assent.

"But if we can't settle here after all—" Wellearn began.

"Then we'll survive at sea!" Skilluck exploded. "The way the wild briqs do!"

"Not even Tempestamer can bear a load like this indefinitely!" Sharprong objected, indicating the puzzled and frightened passengers. "We've had an easy voyage compared with last year, but if there are going to be more storms—"

"Are there not uninhabited islands with springs of fresh water we can put into when our drink-bladders won't suffice? Aren't there capes and coves to offer shelter? And don't we have more seafaring skill in this fleet than ever was assembled outside Ushere?"

Wellearn shivered despite the warmth of the day. Here was a vision more grandiose than his—indeed, than any save Embery's, which pictured travel through the sky.

But what about the rest? Would they agree?

Strongrip said heavily, "We must at least make landfall, Captain. If our companions don't see with their own eyes what you and I might take on trust, there'll be recriminations."

"Those will follow anyway, the first time we run short of food," said Skilluck. "But you're right. We go ashore with all prongs sharp, if only for the chance to rescue wise'uns who know the secret of creshban. All else from Hearthome may go smash—who's going to light a fire in mid-ocean, let alone carry sand or stone to melt for glass and metal? Burn my Tempestamer's back? Never! Safer to use the stuff of life than the stuff of death! But I want creshban!"

Breathing heavily, he turned to Wellearn. "You stay here and keep the passengers soothed. The rest of us—"

"No," said Wellearn firmly. "I'm going ashore, too. If Embery still lives, I want her with me."

"Now you listen to me—" Skilluck began, but Wellearn cut in.

"Here come the other captains! We'd best present a united front."

"Stars curse it, of course! But you can't expect us to load up with every single survivor—"

"Then take her, if I find her, and I'll stay!" Wellearn flared.

"You're being unreasonable—"

"No, Captain. Much more reasonable than you. I've thought this through. If we do take to a nomad life at sea, what are we to do about keeping up our numbers? Already people from Ushere and Hearthome are overbred. We shall have to copy what roving tribes do on land: leave part of our company at the places where we stop in exchange for strangers who want to learn the arts of the sea. It had been in my mind to propose such a policy anyhow, because of a talk I had with Shash. But if we do as you suggest..."

Skilluck clattered his mandibles glumly. He said after a pause, "Well, perhaps there will be some among the passengers who want to take their chances on land, even so far from home, rather than carry on at sea. Salt water isn't in the ichor of us all the way it is in yours and mine."

Wellearn wanted to preen. How short a time ago it seemed that Skilluck had called him a landlubber at pith!

Yet he still was, and it required all his self-control to accept that his hopes of settling at Hearthome had been shattered the way the prong from heaven shattered that berg. Maybe after seeing the city in nuns the idea would come real for him. Until then, he must compose himself. Here came Toughide and Shrewdesign to demand what was happening.

"You expect us, in our condition, to plod ashore and win back Hearthome from its invaders?" Toughide snapped.

So much was to be expected. After the long voyage, few of the briqs were as fit and flourishing as Tempestamer.

"Not at all," was Skilluck's wheedling response. "We only expect the combined talents of the Wego to salvage something from the landlubbers, and above all what's going to be most valuable to ourselves: creshban, of course, but also..." He paused impressively. "Wouldn't you like spyglasses, all of you, better than this one of mine? The Hearthomers have them by the score! I never admitted it, but I craved one myself! Only they wouldn't part with the one I wanted until we'd concluded our alliance ... Still, that's water past the prow. But the observatory where the glasses are kept is nearest the ocean and stands the best chance of having been defended! If we can only attain that hill before we're forced to retreat, and hold a bridgehead long enough to gather provisions, we shall retire with the finest treasure any Wegan could imagine!"

Rearing up to his full remaining height, though that strained his voice to shrillness, he brandished his beloved spyglass for all to see.

"If we don't come back with something better for us all, then you may cast lots for who's to have this!"

Uncertain at the prospect of a battle, for the Wego had never been collectively a fighting folk, Shrewdesign said, "We shan't try to retake the city by force?"

"It would be dreamness to attempt it! But what's of use to us, that the invaders would simply smash because they're starved insane—we must take that!"

Unheeded while the debate was raging, the sun had slanted towards the horizon. Suddenly the tropic night closed down, and there were moans from passengers who had not yet adjusted to the speed of its arrival.

During their last day's travel the fleet had broached a latitude further south than any on their course, and it was now for the first time they saw, at the western rim of the world just above the thin red clouds of evening, a great green curving light, edged like a shuddermaker's rasp.

Silence fell as they turned to gaze at it, bar the slop of water against the briqs' sides and the crying of frightened children. The redness faded; the green grew even brighter.

"What is it?" Skilluck whispered to Wellearn.

"I heard of such things before, and never saw one," was the fault answer. "There are tales about the Blade of Heaven which comes to cut off the lives of the unrighteous—"

"Tales!" Skilluck broke in. "We can do better without those! How about some facts?"

"It's said at Hearthome that when a star flares up—"

"Oh, forget it! Leave it to me!" And Skilluck marched towards Tempestamer's prow, where he could be heard on all the prow-together briqs.

"Chaplains! Stand forth! Tell me if that's not the Blade of Heaven!"

A ragged chorus told him, yes it was.

"Tell me further! Is it poised to cut off the lives of the unrighteous? And is it not unrighteous to leave those who offered to ally with us to suffer at the claws of crazy folk?"

The instant he heard any hint of an answer, he roared, "Well, there's our sign, then! Captains, prepare to moor your briqs! Against that cape there's a shelf of slanting rock where one may bring in even so large a briq as Tempestamer and not make her beach herself! And it's exactly below the observatory we're making for!"

IX

Among the many stories Wellearn had been told when he was a young'un, then taught to disbelieve as he grew up, was a description of what went on in the moon when the righteous and unrighteous were separating. Gradually dividing themselves according to whether they found dark or light more alluring, folk were said to yowl and yammer in imaginary speech; those following star-blessed visions pursued a straight path towards the light, those who doubted kept changing their minds, while only those who had arrived at righteousness by reason were able not to collide with others and be beaten or tripped up and so delayed on their way to the glory of full moon. It was a child's impression of the adult world, perhaps, not stressing what the wicked must have done to deserve the dark.

Skilluck would have been deemed wicked by all the chaplains Wellearn had known, including Blestar, inasmuch as he often mocked and occasionally defied them.

But he was glad to be beside the captain when they went ashore, for what they found was like an actualization of that terrifying childhood story.

No concerted attempt was made to drive off the Wegans who landed; there was neither rationality nor shared insanity to generate resistance. Wild-eyed, stinking, often with their mantles leaking, a horde of starvation-maddened victims ran hither and thither, some sufficiently aware to try and alarm their fellows, many more so distraught that they reacted only to the scent of oozing ichor and under the impression "here's food" began to clap their mandibles excitedly before attacking those who meant to warn them.

It might have been different had the newcomers been exuding combat-stink, but none of them was. They were serious, determined, and—most of all—afraid.

Wellearn was too calm to pretend otherwise. Wherever he glanced, he saw new horrors. One image in particular sank barbs in his memory. There was an elderly man who must have walked, he thought, as far as Tempestamer had swum to get here. For his pads were completely worn away, and he was hobbling along on the under-edge of his mantle with vast and painful effort, no taller than a new-budded child, leaving a broad wet trail like a giant sluq...

For the first time Wellearn realized: there were some dooms far worse than death.

Beating back those who got in their way, using poles from their briqs' saddles in preference to prongs, Skilluck's party breasted the slope below the observatory and obtained their first view of the entire city. Wellearn repressed a cry. The trails of luminous vines which he had seen in Embery's company were being torn loose and waved madly around until they died, as though the bravetrees of all the houses had suddenly developed palsy. Northward, in the quarter of the fireworkers, there was a vast glare on the underside of a pall of smoke, suggesting that all the stored fuel had been set ablaze at once. And the night breeze carried not just fumes but the sound of screaming.

"Looks to me as if they're even crazier over yonder!" Skilluck muttered. "So who's going to want to quit the briqs and settle here? If we can't carry all the sane survivors ... That's the spyglass-house, is it?"

His answer came in the shape of a well-aimed throwing prong, which missed Strongrip by a claw's-breadth. At once they dropped to the ground, prepared to crawl the rest of the way.

"The defenders are still on guard," Wellearn whispered. "I must let them know who we are!"

"But—"

"I know what I'm doing!" And he began to work his way uphill, soilover-style, using his claws and the edges of his mantle instead of his pads.

Sharpening his hearing to its utmost, he caught fault cries up ahead.

"Looks like a well-organized attack! Stand to!"

Another few moments, and a half-score of prongs flew over him. Somewhere behind was a strangled moan.

Moving as fast as he could, he closed the distance to the side of the observatory: that great complex of bravetrees and countless other plants where he had been shown marvels beyond belief. At every gap between their boles protruded a cruel spike instead of the former telescopes, and from roots to crown prongsmen waited to deliver death like a blow from the sky.

He gathered all his force and shouted, "Embery!"

And instantly doubled over, offering the toughest part of his mantle to any missile.

It came—but he felt only a blow, not a stab. The throwing prong skidded away into the undergrowth.

"Someone called my name!" he heard ... or did he? Had tension allowed him to mistake imagination for reality? Straining perception to the utmost, he waited.

And almost rushed to dreamness with relief. No doubt of what he heard this time.

"No, daughter, it isn't possible. The stress has been too much for you—"

"Embery! Shash! Chard!"

Wellearn had to straighten out again to deliver his words with maximum force, and for an instant could imagine the prong that was going to lodge in his mantle. But he went on, "The Wego are here! The Wego are here! Don't—!"

One of the defenders high in the observatory's treetops heard the warning too late. He had taken aim and let go. Wellearn screamed.

But the prong sank into soft ground ... so close, he could feel the quivering impact. After a little, he was able to recover himself and return to normal pressure as Shash and Embery and half a score of their friends rushed to meet him.

Shamelessly embracing Embery under his mantle, as though they were about to mate in public—but she was showing his bud, his bud!—and anyway nobody would have cared if they had, Wellearn translated the conversation going on softly among the trees of the observatory, trying to make himself believe in his own heroism. That was what they were all calling it, Skilluck too ... but it wasn't, it was just that he had done what the situation called for, and anyway most so-called heroes turned out to have been temporarily crazy, living a dream instead of reality.

He forced aside the relics of the chaplains' teachings about reliance on visions, and composed himself to concentrate on his duties as interpreter.

"We saw no signs of organization on the way here," the captain was saying. "Does it break down at night, or is it always the same?"

"At the beginning there was some semblance of order among the invaders," Shash said. He was tired but coherent; his older brother Chard was slumped to the point where he looked as though he needed a sitting-pit, and paying scant attention. "They were able to confront us and— well, that was how we lost Burney. We were fit and rational, and thought they would be too. We now believe they must have been the first of their folk to work out what was happening, to decide that they must leave home and take over someone else's territory. And we assume that others fell in behind them when they realized this was their only hope, but by then they were—well—disturbed. And on the way I guess they infected others with their craziness."

"That fits," Skilluck muttered. "Any idea how far north they came from?"

"What few people we've been able to capture and feed up to the stage where they can talk normally—and there aren't many of those—all agree that the cold weather reaches down to the very pith of this continent. If my brother were better he could tell you more. But he's exhausted." Shash spread his claws helplessly. "The further from the sea, it seems, the worse the cold! We know that water retains heat longer than dry land, but even so, this is terrifying! Are we due for frost and snow here in Hearthome? We've never seen such things! One could imagine the whole world turning into a frozen ball!"

"I don't think we have to fear that," Wellearn said, a little surprised at himself. He parted from Embery and leaned forward. "The way Chard explained it to me, warmth at the equator turns water into vapor, so clouds turn into ice at the poles. But if the sun goes on getting warmer—"

"Quite right!" said Chard unexpectedly, and lapsed back into distraction.

"Forget the theories!" Skilluck snapped. "We need to decide on a plan of action! I have one. We should simply—"

"But what about the Blade of Heaven?"—from Toughide.

"Oh, that!" Chard roused himself completely. "We know about such phenomena. When a star—like the famous New Star—explodes, it throws off gobbets which cool down in the interstellar void. If one approaches another sun, it warms up and boils off part of itself. All this follows from the teaching Jing bequeathed."

"Is this going to save our lives?" Skilluck shouted, erupting to full height. "Are you coining with us? Are you prepared to give us what you want to preserve from Hearthome? Make your minds up now!"

He was so patently correct, Wellearn found himself upright alongside him.

"Yes! And whatever else you give us, we must have the whole of Jing's scriptures!"

"Creshban!" Skilluck shouted, and the other captains echoed him. "If nothing else, we must have the secret of creshban!"

The wind had shifted; there was something menacing in the air that affected their weather-sense, making tempers raw, and it wasn't just smoke.

After a pause filled only by the noise of the crazy folk smashing and ripping through the city, Shash said heavily, "There's no secret to creshban. We don't know why, but fresh sour juices of new-budded fruits or even new-sprouted leaves will do the job so long as they have no animal matter at the roots. Nothing from a briq's back—nothing from a cemetery—only shoots that spring from new bare ground. I'll give you seeds that produce the most suitable plants, but ... Well, essentially it's like eating a proper diet at home, instead of wandering across a desert or an ocean and living on stored food."

"That simple?" Skilluck whispered. "If we'd known—"

"If you'd known you'd never have come back," said Chard unexpectedly. "You said that in Forbish, didn't you?"

There was a thunderstruck pause, while Wellearn registered the fact that he had not actually translated the last statement, and the rest of the Wego captains were looking blank.

"When you first came here, I thought you were better informed than you pretended," said the fat old astronomer. He squeezed himself upright, and even though the effort slurred his speech he overtopped luck, for his was the taller folk. "Did you wonder on the way home last year why we didn't give you all of everything at once? Did you wonder whether we realized your intention was to cheat us if you could?"

Skilluck cowered back in a way Wellearn had never imagined he would see, not in his wildest fantasies. Chard blasted on.

"But it doesn't matter anymore, does it? You kept your pledge to return, and you didn't know you were going to find us in these straits! You've met your honorable obligation, and it remains for us to match the bargain! Take what you can—everything you can, including people!—from this doomed city! Take telescopes and microscopes, take vines and blades and seeds and tools and medicines, and flee at once! Until dawn the attackers will be sluggish, but if you delay past then—! Leave us, the old ones! Leave everything except what your briqs can carry without sulking! And above all, take Jing's scriptures! Wellearn, here!" He bowed himself to a dark corner and pulled out a glass jar.

"Take the originals! We salvaged them first of all, of course, and here they are. Now they're yours. Use them as best you can. If you must, leave them where they will freeze. But don't destroy them! As for us, of course ..."

"No! No!" Embery cried, hastening to his side. "I won't leave you, I won't leave father!"

"You'll have to leave me," Chard said gently. "But you'll go, won't you, Shash?"

"They've turned our healing-house into a jungle," the chief curer said. "They've rooted out our medicinal plants. If I stay, the stars alone know what use I could be to our folk."

"Go, then. Me, I'm much too old." Chard settled back comfortably where he had been. "Besides, I'm fat and I'd probably sink even a handsome briq like Tempestamer. Take your leave and let me be. And dream of me kindly, if you will."

Soberly, the visitors prepared to depart. As they were clasping claws with him, he added, "Oh, captain, one more thing, which might be useful to you in your navigation—that is, if you haven't already noticed it. The end of the comet which you call the Blade of Heaven always points directly away from the sun. It might amuse you, Wellearn, when you have nothing better to occupy your mind, to devise a theory which will account for that."

"I'll try," Wellearn said doubtfully. "But without the means to conduct experiments—"

"There are always means to conduct experiments. And aren't you part of the greatest experiment of all?"

X

During the hours of darkness some of the briqs' passengers had indeed decided they would rather settle on shore and take their chances. As dawn broke they were heading south, together with several score refugees from Hearthome, in search of a site that would be easier to defend.

Meantime Skilluck's party was working out what of their loads—hastily collected in the city—would be least useful, and ruthlessly discarding whatever they did not regard as indispensable. Before the day's heat had fully roused the crazy invaders, the booty had been distributed and so had the two-score Hearthomers who were prepared to risk the ocean.

Skilluck prodded Tempestamer with his goad, and she withdrew her mooring tentacles and made for open water.

"What did uncle mean when he called us an experiment?" Embery asked her father.

"We're mixing like different metals, to see what alloy will result," Shash answered, clinging anxiously to the briq's saddle as they felt the first waves. "It's the start of a new age, whatever the outcome."

"I liked the old one," Wellearn muttered. "And I've been cheated of my share in it."

"Don't think like that!" admonished the old man. "Even the stars can change! And what are we compared to them?"

"We don't yet know," said Embery. "But one day we shall go there and find out."

Overhearing as he issued orders to his crew, Skilluck gave a roar of sardonic laughter.

"Bring me the briq you want to swim to heaven on, and I will personally pith her! Me, with a northfinder I can trust and Tempestamer under me, I'll be content. Now let's go find a herd of wild briqs and start recruiting our new fleet. It's going to be the grandest ever seen!"

But despite the hotness of his words and the bright rays of the morning sun, the wind struck chill from the north.

PART THREE

THE

OUTPOURING

I

When northern summer ceased, the weight of ice leaned hard on those gnarled rocks which fearful wanderers had named The Guardians of the Pole. Slanting up either side of an underwater shelf that grudgingly permitted the highest tides to wash over it, they resembled prongsmen turned to stone, their mantles drawn aside and weapons clutched in both their claws.

Few were the mariners who braved the channel they defined; fewer still the ones who returned to tell of a colossal valley surrounding a landlocked sea so salt that what ordinarily ought to sink there was buoyed up. It was a foul and poisoned zone, though life endured. Chill and salt conspired to make its growths disgusting in the maw. Desperate commanders who imagined their junqs would nourish themselves off such weed as the water sustained watched in horror how first the drink-bladders burst, then the floats, and finally the major tubules, so they died.

By then, of course, the crews that clung to their haodahs were for the most part much too mad to care.

For a while after the last summer the Salty Sea remained liquid, roiling under hail and gale. At length, however, ice filled the valley and beset the Polar Guardians, shattering the rock they were composed of, and down it sped to gather on the shelf. In a single season boulders and ice were too high-piled for any wanner Sow to pass. After that glaciers shed bergs until the isolated sea was covered; then it froze also.

The last foolhardy travelers who let a poorly-pithed briq carry them into such latitudes, thinking that because they had rounded Southmost Cape they were safe from the enmity of the stars, unaware that the briq knew nothing of this ocean dominated by junqs and was lost and panicking, struggled ashore on a desolate beach with the precious secrets it was their task to spread around the world, and sought shelter in a cave which became their tomb.

II

The water was rising, or the land was sinking. Either way the event spelled trouble for the people of Ripar, despite the work of their far-famed inventor Yockerbow.

Some of the inhabitants claimed that their city was the oldest in the world. Others, more cautious, admitted that its records might have been—as it were—revised, because the rotting trunks of sweetwater trees had been found too far out in the lagoon for them to date back to the age of the alleged foundation, when salt tides rolled a long day's walk inland and Ripar River was as yet unfed by its giant tributary, the Gush.

It was thanks to the latter's change of course that the city had flourished. Reason, and relics exposed when mud was being pumped away from the harbor, combined to suggest that originally it had been a mere hamlet, huddled on a narrow flood-plain constricted between dry plateaux. Only when (and this was attested not by legend alone but by recent discoveries) a ball of blazing rock fell out of the sky and blocked the old channel of the Gush was there enough fresh water for dense roots to lock up silt and build a delta, forcing back the sea.

Now a score-of-score-of-scores of people, at the lowest estimate, swarmed along its branchways, got on one another's pith and cursed and sometimes fought and always schemed to secure more than their proper share of the goods attracted to this uniquely sited entrepot, whether they arrived by junq or were carried by a caravan of droms. The majority cared nothing for the past and little for the future. Their homes grew of their own accord, did they not? There was always sustenance, though it be dull, to be snatched from an overhanging bough or filched from a plot of funqi or—if all else failed and they must endure actual work—dragged up on a line from the lagoon. Fish did not abound as formerly, of course, but even mudbanks supported crupshells and other edible mollusqs.

So they were as content as the folk of any big city.

That was the majority. There were, however, others whose traditional obligation was to view Ripar in the context of the world: not only of the globe, but of the universe which comprehended all time and all space. It was said they possessed arcane knowledge dating back before the Northern Freeze. Always there were half a score of them; always they were presided over by the incumbent Doq; always they were collectively disliked because they levied duty on cargoes passing from sea to land or vice versa, and because they enforced the ancient laws with neither fear nor favor. Were one among their own number to succumb to a plague brought by strangers, for which no cure was known, he would quit the city himself before prongsmen came to expel him; were one of his relatives to enter into an unauthorized mating, he would be prompt to bring the new-budded youngling before a eugenic court to determine its fitness to survive; were it his own home that became infested with teredonts, or boraways, or a putrefying mold, he would be the first to pour the poison at its roots.

And it was among these notable and austere personages—short of their customary total by one, for the doyen Chelp had died a few days earlier—that the inventor Yockerbow was summoned to stand today, beneath the interlaced branches of the Doqal Hall, with water plashing underpad. Acutely conscious of being no more than half as old as anyone else present, he strove to reason out why he had been sent for. Surely it could not be, as his beautiful spouse Arranth insisted, that he was to be invited to replace Chelp! His weather-sense informed him that the idea was ridiculous, for the peers were exuding a distinct aura of incipient panic.

But the fact was in no way reassuring.

He sought some kind of signal from Iddromane, spokesman for those who worked with fire and metal, and the only one of the peers he could claim close acquaintance with, but the old fellow remained stolidly imperturbable.

Yockerbow trembled a little.

Then the period of waiting was over, and the Doq rose to his full height.

"Greetings to my brothers, and to Yockerbow the stranger, who is uninformed concerning the reason for his attendance. All will be made clear in moments.

"Since time immemorial"—catching on, Yockerbow glossed that as meaning, in practice, a few score-of-score years—"the Great Fleet of the Eastern Sea has enjoyed harborage rights at Ripar. It has been a considerable while since those rights were exercised. Today, however, notice has been served that the Fleet is to call here very shortly."

So that was it! Making no attempt to maintain a stoical demeanor like the others, Yockerbow clenched his claws. He was schooled in history, and knew that there had been times when a visit by the Fleet was welcome; then the folk boasted how they on land shared ancestors with the People of the Sea, and clamored to trade and intermarry. On the other claw, there had been occasions when the Fleet arrived storm-bedraggled and half-starved, and crazed mariners stole what they could and spoiled the rest, whereupon the folk vowed they could never be called kin to such monsters.

Yockerbow's lifetime had elapsed without a sight of the Fleet; it was working the broadest equatorial waters. Reports from travelers indicated that it had a new commander—land-budded, they said as one—who, having deposed the former admiral, was interesting himself more than any of his predecessors in what the continents could offer.

His name, they said, was Barratong, and his shadow fell across the day-half of the world at every dawn. In Yumbit he had agents who seized the sharp spice remotaw and made it a monopoly for those he favored; in Clophical his prongsmen guarded the giant trees beloved of the spuder, and each autumn they rolled up as many webs as a junq could carry and used them for rope to snare wild junqlings and increase the Fleet; in fabled Grench—yes, he had ventured so far!—he held the sole right to export the fine wax known as cleb.

And he was coming here!

Briefly, alarm drove Yockerbow into imagining an unrealized threat. His lovely Arranth had never made any secret of how, as a youngling, she had dreamed of being traded to the Fleet, of touring the globe as the favorite partner of its admiral. Still, after so many years together ... He had never, though, quite understood why someone like her, so fascinated by the skies, so able to make the dead past come alive, should want to be a partner in his own mundane toil...

"The Fleet's new commander," the Doq was saying in a rasping voice, "has sent word that he wishes to examine the famous novelties of our city: to wit, the pumps which have enabled us to withstand the encroachments of the sea. But that is not the only reason for the presence of a stranger. Immediately on the demise of our late brother Chelp, our brother Iddromane advanced Yockerbow's claim to be his replacement. Without his aid, the boles of this hall might be shriveling under the impact of salt water. Moreover, he is city-born and none has been found to speak a word against him. It would certainly be fitting were he to join us in the ranks of the Jingfired."

But this was incredible! How could Arranth's prediction possibly be right, when the aura of everybody present was so wrong? Besides, Yockerbow had no ambitions in that direction, whatever plans his spouse might have.

A murmur of conversation had broken out. Enjoying silence with a clatter of his mandibles, the Doq continued.

"There is, however, an alternative opinion. Because it is without precedent we have agreed that Yockerbow shall be present when it is put to the vote. It has been suggested that Barratong be inducted to make up the minyum. Some say he is of the commonalty. True, but he has attained the counterpart of noble status. It is known that the Great Fleet is increasing so fast because from every continent—let alone the islands—folk are flocking to him like cloudcrawlers at migration-time. His declared intention, we are told, is to make us all citizens of a global community. Those among us who are concerned with the future limitations of Ripar, its dependence not only on what others bring us from inland or abroad but on the natural process of weather and climate, faced with the undeniable rise in sea-level which is now putting us to such shifts, should be the first to applaud! And nowhere in the ancient scriptures is it laid down that our Order must be confined to city-budded persons!"

Chill certainty pervaded Yockerbow. He had been drawn into an argument the rights and wrongs of which the Doq had already decided in his own mind, but which other of the peers had doubts about. Now all were looking at him expectantly. What should he say? Should he risk the disfavor of the Doq? Knowing nothing of the intrigues of the Order, he felt hopeless. Hoping for guidance, he glanced at Iddromane, but—as ever—he was preserving perfect impassivity.

Well, then, he must trust to his own feelings, and even though he was sure Arranth would be angry with him afterwards, he could deal with that problem when it arose.

"Speak freely!" the Doq urged. "In meetings of the Order neither dissimulation nor subterfuge is permitted!"

Thus instructed, Yockerbow had the temerity to rise to his full height.

"Within or without the compass of your Order," he declared, "you can rely on me to serve our city. So if by inducting Barratong you may hope to enlist his support for our welfare in the future, I say do it!"

The resultant exudations, in the close air of the hall, made Yockerbow feel as though he were lost at sea and a storm were bearing down on him. Yet, though there was still no sign from Iddromane, the Doq was regarding him benignly.

"Well said!" he announced. "Iddromane, you deserve credit for proposing to the Order someone who can take the long view! Be it then resolved that during his visit we invite the admiral of the Great Fleet to join the Jingfired, inasmuch as what he is doing is in accord with our ultimate aims!"

When the Doq had retired, some of the Order came to clasp claws with Yockerbow and compliment him on his selflessness; others departed wearing scowls. Bewildered, he made shift to answer politely, having only the vaguest notion of what he was supposed to have done right.

III

Never had Arranth been in such a rage! It was futile for Yockerbow to try and calm her; all she could say, over and over, was, "You had the chance to join the Order of the Jingfired, and you turned it down!"

He countered in his most reasonable tones that he had had no assurance of being elected—that if he had been by a bare majority he would have made himself enemies for life instead of, as it turned out, enjoying the patronage of the Doq—that the administrative duties such rank entailed would have interfered with his work. She refused to listen. She merely repeated facts which he already knew, as though he were some dull-witted youngling who should have been spotted by the eugenic courts.

"The Order is so old, no one can tell when it began! They say it dates back before the Northern Freeze! Its articles have been copied and copied until scarcely anyone can read them—but I'm sure I could, if I had the chance, and I'd have had it if you weren't a fool! Or maybe I ought to call you a coward! The path to secret wisdom lay before you, and you turned aside!"

"My dear, what's supposed to be so secret?" he rejoined. "You told me how your cousin Rafflek, who was then attendant on the Doq, reported what he overheard them saying during an induction rite: "The stars aren't fixed, and sometimes they blaze up!' So much you could be told by any of your friends who study sky-lore!"

"That's not the point!"

"I say it is! All right, some stars aren't stars but only planets, and our world is one of them. All right, other stars may be suns with planets of their own—I see no reason why not! But saying they're inhabited is about as useful as telling me that something's happening in the Antipads, or something happened in the far past! Without means of either communicating with these folk, or visiting them, what good is there in making such a statement?"

"That doesn't mean they don't exist!"

"Well, no, of course it doesn't—"

"And even if we can't communicate with the past, the past can communicate with us, and often does so without intention! Your pumps have sucked up ancient tools in the harbor, and scholars like Chimple and Verayze have worked out how the folk of that distant day employed them! So I'm right and you're wrong!"

As usual, Yockerbow subsided with a sigh, though he still wanted to attack her logic. It was, after all, true that his spouse was highly regarded in intellectual circles, though he did sometimes wonder whether it was because she really displayed such an outstanding knowledge of astronomy and archeology, or whether it was due rather to her slender grace and flawless mantle...

No, that was unworthy. But, for the life of him, he could not share her obsession with the improvable! You didn't need a telescope to discern how the moon's turning, and to some extent the sun's, affected the tides, for instance. But the planets obviously did not; records of water-level had been kept for so long that any such phenomenon must by now be manifest. Therefore the night sky was a mere backdrop to the world's events, and even if there were reasoning beings on other planets, without a way to contact them their existence was irrelevant. Certain authorities claimed there were creatures in the sun, what was more! They argued that the celebrated dark spots on its brilliant surface indicated a cool zone below a layer of white-hot air. And there were dark and light areas on the moon, too, which the same people held to be seas and continents. Given their chance, as Arranth wished, they would have imposed their convictions as dogma on all Ripar!

Perhaps he should wait on the Public Eugenicist and accuse his predecessor of authorizing a mistaken pairing. Things would have been so much simpler had they budded...

Yet he could not imagine living alone, and what other spouse could he find who was so stimulating, even though she was infuriating in equal measure?

Finally, to his vast relief, she lost patience, and made for the exit.

"I'm going to Observatory Hill!" she announced. "And while I'm up there, you can think about this! I look forward to meeting Barratong! I gather he recognizes merit in a female when he finds it! Maybe I can still fulfill my old ambition, and tour the globe aboard his banner junq!"

And off she flounced.

As the screen of creepers around their bower rustled back into place, Yockerbow comforted himself with the reflection that in the past a night of stargazing had always calmed her mind.

He could not, though, wholly persuade himself that the past was going to be any guide to the future.

But there was work to be done if the admiral was to admire the latest achievement of his beloved city. And he did love Ripar. He could conceive of no more splendid vista than the parallel ranks of giantrees which flanked its access to the ocean, no more colorful sight than the massed bundifloras ringing the lagoon, no sweeter perfume than what drifted up at nightfall from the folilonges as they closed until the dawn.

And he, for all his youth and diffidence, had saved Ripar, thanks to nothing better than sheer curiosity.

At least, that was his own opinion of what he'd done. Others seemed awestruck by what he regarded as obvious, and talked about his brilliance, even his genius. Yet anybody, in his view, might have done the same, given the opportunity. He was not even the first to try and protect Ripar by means of pumps. All along this coast, and far inland, folk made use of syphonids. Their huge and hollow stems could be trained, with patience, so that they might supply a settlement that lacked nothing else with fresh water from a distant lake, albeit there was higher ground between. But in cool weather their action grew sluggish, and sometimes air-locks developed in the stems and the flow failed.

On the coast, cutinates had also long been exploited. These were sessile creatures like immobile junqs that fed above the tide-line by trapping small game in sticky tentacles, yet to digest what they caught required salt water, which they sucked up from inshore shallows and trapped by means of flap-like valves. Fisherfolk would agitate one of them at low tide by offering it a scrap of meat, then gather stranded fish from drying pools as the water was pumped away.

Yockerbow's interest had been attracted to cutinates when he was still a youngling barely able to hold himself upright, by the odd fact that no matter how far inland the creatures might reach (and some attained many score padlongs) they never exceeded a certain height above sea-level, as though some invisible barrier extended over them.

Once, long ago, someone had thought of forcibly connecting a cutinate to a syphonid, so that any air-bubbles which formed in the latter would be driven out by the water-pressure. The project failed; for one thing, the syphonid rotted where it was connected to the cutinate, and for another, the cutinate would only pass water so salt it was useless for either drinking or irrigation.

But the young Yockerbow was excited by the idea of finding practical applications for these abundant creatures. When he discovered that airlocks in syphonids always developed at exactly the same height above water-level as was represented by the limit of the cutinates' spread, he was so astonished that he determined to solve the mystery.

The key came to him when, after a violent storm, he found a cutinate that had been ripped open lengthways, so that its internal tube was no longer watertight. Yet it was far from dead; still having one end in the sea and—fortuitously—the other in a pool left by the heavy rain, it was pulsing regularly in a final reflex spasm.

Yockerbow contrived a blade from a broken flinq with two sharp edges, cut away the longest intact muscles, and carried it home, along with a mugshell full of seawater. To the surprise of his family, he was able to demonstrate that the cutinate's activity depended less on its intrinsic vitality, as the scholars of the city were accustomed to assume, than on the simple relation between salt and fresh water. And then he discovered that, if vegetable material or scraps of meat were steeped in the fresh water, the muscle could actually be made to grow...

Lofty and remote, Iddromane came to hear about his work, and sent a messenger to inquire about it, who was sufficiently impressed to suggest that his master invite Yockerbow to wait on him. That was their only private meeting; they had crossed one another's path frequently since, but always at formal events such as season-rites or disposition-meets.

Iddromane's influence, however, was such that when he timidly put forward his idea that detached muscles might do useful work in pumping away flood-water from the city's outermost sea-wall, Yockerbow was overwhelmed with offers of assistance. There were several false starts; at first, for example, he imagined he could overcome the height problem by arranging the muscles to squeeze a succession of ascending bladders with flap-valves in between. That worked after a fashion, but the bladders kept rupturing and synchronization proved impossible. After a year of trial and error—mostly error—he was about ready to give up when one disconsolate day he was wandering along the shore and noticed a long thin log which the retreating tide had stranded so that its heavy root end lay on one side of an outcropping rock and its thin light spike end on the other. The rock was closer to the root than the spike; as the water withdrew, there came a moment when the log was exactly balanced, and hung with both ends clear of the ground.

Then a mass of wet mud fell away from the roots and the balance was disturbed and the log tilted towards its spike end and shortly rolled off the rock. But Yockerbow had seen enough.

A month later, he had the first pumping-cluster of cutinate muscles at work. Grouped so close together they had to synchronize, they shrank in unison to half their normal length, then relaxed again, exerting a force that five-score strong adults could not outdo. By way of a precisely fulcrumed log, they pulled a plunger sliding inside a dead, dried syphonid, which led to the bottom of a tidal pool. At the top of its travel, the plunger passed a flap-valve lashed to the side of the tube, and water spilled through and ran off back to the ocean.

Much development work followed; in particular, the cords attached to the plunger kept breaking, so that Iddromane had to authorize the dispatch of an agent to bargain for a batch of spuder-web—doubtless thereby arousing the interest of Barratong, for only his factors were entitled to market the webs on this side of the ocean. That problem solved, means had to be found of ensuring that the plunger dropped back to the bottom of its course without jamming halfway; again, that called for an agent to travel abroad in search of cleb, the astonishing wax which, pressed upon from the side, was as rigid as oaq, yet allowed anything to glide over its surface be it as rough as rasper-skin.

With a ring of flexible hide around it, the plunger on its web-strand slid back and forth as easily as might be hoped for, and every pulse of the combined muscles could raise the volume of a person in the form of water.

But the purchase of cleb had also been notified to Barratong, and beyond a doubt that must have been what decided him to call here after so long an absence of the Fleet. For now travelers came to gape at the ranked batteries of pumps which, working night and day, protected Ripar from the ravages of the ocean. As often as the tide flooded salt water into the outer lagoon, where it was trapped behind a succession of graded banks, so often did the pumps expel it and allow fresh water back to keep the giantrees in health. A few were wilting, even so, but very few, and the routine difference in water-level was a half-score padlongs.

To Yockerbow's intense annoyance, though, people who ought to have known better—including some members of Iddromane's entourage—expected him to increase this margin indefinitely. To them he spoke as vainly as to Arranth. He said, "I've tried to raise water further than the height represented by the limit of cutinate growth, and it won't work." Not even Arranth believed him; she was more and more rude to him nowadays, and he felt certain it was because he "wouldn't" improve his pumps.

And nobody shared his excitement at the probable implications of his discovery. It seemed to him that the only explanation must be that air was pressing down the water in a pump-tube, so when the weight of water lifted matched the weight of the overlying air, it would rise no further. He had contrived some elegant demonstrations of the theory, using clear glass tubes supplied by one of Iddromane's associates, but not even Arranth would take them seriously. She believed, as everybody did, that air had neither weight nor—what would follow—limitations to its upward extent. Solid substances had much weight; liquids, rather less, because they incorporated more fire; but air's must be negligible, because it filled the universe and neither obstructed nor slowed down the planets. And if the stars were fire, and fire could not burn without air—as was proven by covering good dry fuel, after setting it alight, with something impervious—then there must be air around the stars.

"But just suppose," he argued vainly, "that starfire is different from regular fire—"

"Now you're asking me to believe something much more ridiculous than that the planets are inhabited!" Arranth would crow in triumph, and that was always where the discussion ended, because he had no counter to that.

So, having unproved his pumps as far as they would go, he was turning his attention to other matters. He was trying to make a connection between fire and mere heat; he was testing everything known to create warmth, especially rubbing, and he was approaching a theory to explain the brightness of the stones that fell from heaven. It was generally accepted that the glowing streaks which nightly crossed the sky were of the same nature as the lumps of hot rock that were sometimes found at the probable point of impact of one of them. Burning rock? Well, rock could be melted, and if air contained more of the principle of fire the higher one went...

It was tolerably logical, that idea. Yet it failed to satisfy Yockerbow, and on the occasions when he had joined Arranth at the observatory on the high hill to the east of Ripar, where there were many good telescopes and files of records extending back nine-score years—it should have been far longer, but a disastrous winter had flooded the pit where earlier records were stored, and they rotted—he always came away disappointed. Some of the astronomers listened to his ideas politely, but in the end they always made it clear that to them he was no more than a lowly artisan, whereas they were refined and erudite scholars.

It was their disrespect which had hardened his view of them, rather than any secure belief that their explanations of the stars were wrong. Essentially, he could not accept the probability of such people being completely right.

And, little by little, he was formulating concepts which he knew made better sense. Suppose he had broached them to the Order of the Jingfired, after insisting on being inducted as Iddromane proposed...?

No, the outcome would have been disastrous. He knew little of the web of intrigue in which the peers held Ripar like a catch of squirmers in a fish-hunter's basket, but he had the clear impression that mastering its complexities must be like trying to weave a net out of live yarworms. Had he uttered his heretical notions in such august company, means would have been found to replace him prematurely. Radicals, revolutionaries, had no place in the deliberations of the Order.

Yockerbow felt caged and frustrated. What he had expected to flow from the acceptance of his pumps, he could not have said. Certainly, though, it had not been anything like this sense of impotence and bafflement. In a word, he was indescribably disappointed by the reaction of his fellow citizens.

Suddenly he found he was looking forward as keenly as Arranth to the arrival of Barratong. Maybe someone who had traveled half the globe would be more open to new ideas than those who sat here smug behind the defenses he had contrived but paid scant attention to the inventor's other views.

IV

First there was a pale line of phosphorescence on the pre-dawn horizon, so faint only the keenest-eyed could detect it. Then it resolved into individual points of light, each signifying the presence of a junq festooned as lavishly with glowvines as any palace in Ripar. And at last, just as the sun cleared the horizon, the entire Fleet came into sight of land, and the city's breath seemed to stop collectively.

The Fleet was huge! Records indicated it had never exceeded four score junqs; now there were seven score, and another score of younglings followed behind, secured with hawsers made of spuder-web until they were safely broken. Each of the adults carried an enormous haodah beset with edible funqi and other useful secondary plants, and each haodah was as warm with people, from those so old their mantles were shrunken with age down to children who could not yet stand upright, and nonetheless clambered with infinite confidence from pole to creeper to outlying float.

"It looks more like a mobile city than a Fleet!" marveled Yockerbow, and he was not alone.

And the resemblance was magnified a scorefold when, responding to a perfectly drilled system of signals issued by gongs and banners, the junqs closed on the place allotted for their mooring and came to rest, prow against stern, so that one might walk dry-padded from each to the next and finally, by way of the leading junq, to shore.

"That must be Barratong!" Arranth exclaimed, surveying the wondrous spectacle through a borrowed spyglass.

"Where?" Yockerbow demanded. Passing the glass to him, she pointed out a tall, burly fellow at the prow of the lead junq.

"I think not," Yockerbow said after a pause.

"What? Oh, you're always contradicting me!" She stamped her pad.

"He doesn't match the descriptions," was his mild reply. "The person directly behind him does."

"Are you sure? He looks so—so ordinary!"

And it was true. Apart from combining northern shortness with a southerner's pale mantle, he looked in no way exceptional, but he wore crossed baldrics from which depended the ancient symbols of his rank, a spyglass and an old-style steersman's goad, and his companions deferred to him even in their posture.

The Doq and the eight peers were waiting for him, surrounded by their entire retinue, and moved to greet him the moment he climbed down from the junq. After that he was invisible from where Yockerbow and Arranth stood, and the group moved off towards the Doqal Hall where a grand reception had been prepared.

"We should be going with them!" Arranth said accusingly. "If you'd asked Iddromane like I suggested, I'm sure he—"

Yockerbow fixed her with a rock-hard glare.

"No! Am I to wait on him, like a humble underling? Has it not occurred to you, my dear, that he is coming to see me?"

Her eye widened enormously. After a moment she began to laugh.

"Oh, my clever spouse! Of course you're right! It's much more remarkable like that! It's going to make us famous!"

As if we weren't already ... But it didn't matter. He had made his point, and there was work to do.

It was not long before the mood of excitement generated by the Fleet's arrival started to give way to annoyance. This was not because the visitors were discourteous or rapacious; they traded honestly for what they found on offer, and conducted themselves with tolerable good manners albeit some of them, especially those who hailed from the distant south, had very different customs.

More, it was that they seemed somewhat patronizing about even the best that Ripar had to show, and in this they took after the admiral himself. Blunt, plain-spoken, he refused to be as impressed as the peers expected by anything about the city, including its alleged antiquity, for— as he declared in tones that brooked no denial—his Fleet could trace its origins back to within a score-score years of the inception of the Freeze, when briq-commanders from the west were storm-driven into what was for them a new ocean and found not wild briqs but wild junqs, which none before them had thought to try and tame, yet which proved far superior: more intelligent and more docile, not requiring to be pithed. He even had the audacity to hint that Ripar had probably been a settlement planted by the early seafarers, and that contradicted all the city's legends.

He compounded his offense when, having enjoyed the greatest honor they could bestow on him and been inducted to the Order of the Jingfired, he made it unmistakably plain that that too was delaying fulfillment of his chief purpose in calling here: inspection of Yockerbow's pumping-system.

The peers seethed. That anyone should find the work of a commoner, a mere artisan, of greater concern than their most ancient rituals...!

They yielded perforce, thinking what the Fleet might do were its commander to lose his temper, and sent urgent messages to Yockerbow to meet them on the outer harbor bank.

To the intense annoyance of Yockerbow, but the huge amusement of a crowd of bystanders who had come here to catch a glimpse of the famous admiral, Arranth was rushing up and down in a tizzy of excitement, like a girl waiting to greet her first lover. Not until the procession of the peers and their attendants actually stepped on the high bank did she suddenly realize how unbefitting her behavior was. Speech—fortunately—failed her long enough for Barratong to pace ahead of his companions and confront Yockerbow person-to-person.

"So you're the celebrated inventor, are you?" he said, gazing up at the Riparian who had clean forgotten that, according to normal rules of politeness, he should have reduced his pressure so as not to overtop the distinguished visitor. "I like you on sight. You don't pretend to be what you are not—a stumpy little fellow like myself!" He added in a lower, private tone: "That Doq of yours must be aching in all his tubules by this time! Serve him right!"

At which point, while Yockerbow was still overcome with astonishment, Arranth recovered her self-possession and advanced with all the dazzling charm at her disposal. From somewhere she had obtained thick, fine strands of sparkleweed and draped them about her body in rough imitation of the admiral's baldrics; this, she hoped, would not only be taken as a compliment but maybe start a trend among fashionable circles.

"Admiral, what an honor you've bestowed on us by coming here! I so much crave the chance to talk with you! You know, when I was a girl I used to dream the Fleet might call here so I might beg the chance to make a trip with it and see the stars of the far southern skies for myself— astronomy, you see, is my own particular interest!"

"Then you should talk to Ulgrim, my chief navigator," said Barratong, and deliberately turned his back. "Now, Master Yockerbow, explain your pumps! I came here specially to see them, because—as you can probably imagine—every now and then the Fleet at sea runs into the kind of waves we can't rely on riding, and often our junqs are weighed down by water which we have to bale out with our own claws before they can swim at full speed again. In the wild state, as I'm sure you know, they never experience such swamping, because their flotation bladders always bear them up, so they have no reflexes of their own to cope with such a situation. Still, we've taught them to endure and indeed nourish all sorts of parasitic plants, so maybe we can add something more. Do we go this way?"

He made for the nearest working pump, and Yockerbow hastened to keep pace with him. Nervously he said, "I believe I should congratulate you, shouldn't I?"

"What for, in particular?"

"Were you not just inducted into the Order of the Jingfired?"

"Oh, that!"—with casual contempt. "Sure I was. But I gather its teaching is supposed to be secret, and I can't for the life of me see why. If it's true, then the more people who know about it, the better, and if it isn't, then it's high time it was exposed to ridicule and correction."

The peers who had remained within earshot stiffened in horror at the prospect of this rough intruder revealing their most sacred secrets. Barratong paid no attention. His aroma had the tang of one accustomed to bellowing orders into the mandibles of a gale, and his self-confidence was infectious. Yockerbow found he was able to relax at last.

"Now here you see a pump actually working," he said. "The tide being on the turn, there's relatively little water left beyond this bank. If you want to inspect a dismounted pump, we have one available..."

Barratong's ceaseless questioning continued all day and long past sunset, while Arranth hovered sullenly nearby and kept trying to interrupt. At last she managed to make him angry, and he rounded on her.

"If you're so well grounded in star-lore, you can tell me the interval between conjunctions of Swiftyouth and Steadyman!"

"It depends on our world's position in its orbit! The year of Swiftyouth is 940 days, that of Steadyman is 1,900, and our own—as you may perhaps know!—is 550." Clenching her claws, she positively spat the words.

Softening a little, Barratong gave a nod. "Very good! Though I still say Ulgrim is the person you ought to be talking to, not me, a common mariner."

"The most uncommon mariner I ever met!" blurted Yockerbow.

Pleased, Barratong gave a low chuckle. "I could honestly match the compliment," he said. "For such a big city, it has precious few people in it worth meeting. I was introduced, though, to some folk called Chimple and Verayze, who do at least base what they say about the history of Ripar on solid evidence."

"We found it for them!" Arranth exclaimed, then amended hastily, "Well, it turned up in the mud the pumps sucked..."

"Yes, of course: they told me so." Barratong shook himself and seemed to return to reality from far away. "As it happens, I'm engaged to dine with those two, and it's dark now. You come with me. I find you, as I just said, interesting."

Neglected, insulted, the peers had long ago departed in high dudgeon. There was no one else on the sea-bank except a few dogged onlookers and a couple of Barratong's aides.

"It will be an honor," Yockerbow said solemnly, and could not resist whispering to Arranth as they followed in the admiral's brisk pad-marks, "Isn't this better than being on the outer fringes of some banquet in the Doqal Hall?"

Her answer—and how it carried him back to their time of courting!— was to squeeze his mantle delicately with her claw.

They met with Chimple and Verayze at Iddromane's bower on the south side of the city, where the plashing of waves mingled with music from a flower-decked arbor. It was blessed with the most luscious-scented food-plants Yockerbow had ever encountered, many being carefully nurtured imports. Even the chowtrees had an unfamiliar flavor.

Yet the admiral paid scant attention to the fare his host offered, and at first the latter was inclined to be offended. Yockerbow too began by thinking it was because, after voyaging to so many fabulous countries, Barratong had grown blase. In a little, though, the truth dawned on him. The signs, once recognized, were unmistakable.

Barratong was in the grip of a vision budded of his vivid imagination, yet founded securely upon fact—a vision of a kind it was given to few to endure without slipping into fatal dreamness. Yockerbow trembled and lost his appetite. Now he understood how Barratong had attained his present eminence.

Musing aloud, the admiral captivated everyone in hearing with words that in themselves were such as anybody might have used, yet summed to an awe-inspiring total greater than the rest of them would dare to utter.

"The ocean rises," he said first. "It follows that the Freeze is ending. If it began, it can just as well end, correct? So what will follow? We've tried to find out. The Fleet has put scouts ashore at bay after cove after inlet and found traces of the higher water-levels of the past. How much of the ocean is lucked up in the polar caps we shall discover when the continued warming of the sun releases it. You here at Ripar, despite your wealth and cleverness—despite your pumps!—will have to drag your pads inland and quarrel for possession of high ground with the folk who already live there. You!"—this to Iddromane—"with all your ancient lore, in your famous Order, why did you not speak of this when you inducted me?"

Iddromane's notorious composure strained almost, but not quite, to the bursting point. He answered, "Truth is truth, regardless of when it was established."

"I don't agree. Truth is to be found out by slow degrees, and the world changes in order to instruct us about truth, to save us from assuming that what was so in the past is necessarily bound to be the case tomorrow, too. I'm sure our friends who study relics of the past will support me, won't you?" This with a meaningful glare.

Chimple and Verayze exchanged glances, then indicated polite assent.

"And how say you, Master Inventor?"

Yockerbow hesitated, seeking a way to offend neither Iddromane nor Barratong, and eventually said, "Perhaps there is more than one kind of truth. Perhaps there is the kind we have always known, truth about ourselves and our relations with each other, and then maybe there's the kind which is only gradually revealed to us because we actively seek it out by exploration and experiment."

"Most diplomatically spoken!" said the admiral, and exploded into a roar of laughter. "But what's your view of the origin of the universe? In Grench they hold that once all the stars were gathered right here, in the same world as ourselves, and the advent of unrighteousness caused them to retreat to the furthest heaven in shame at our behavior. In Clophical they say the departure of the stars was a natural and inevitable phenomenon, but that that was the cause of the Northern Freeze, and hence, if the ice is melting again, the stars must be drawing closer once more!"

"If only we could tell one way or the other!" sighed Arranth. "But though it's suspected that the stars move, as well as the planets—if not so visibly—our astronomers have so far failed to demonstrate the fact. Am I not correct, Master Iddromane?"

"Not entirely," was the judicious answer. "Careful observation does indicate that certain stars must be closer to us than others. As the world progresses around the sun, a minute difference in position—relative position, that is, of course—can be detected in a few cases. They are so few, however, that we are unable to decide whether the shift is solely due to a change of perspective, or whether part is motion proper to the stars themselves. The distances involved are so great, you know, Admiral, that if your Fleet could swim through the sky it would take a score-of-score-of-score years to pass the outermost planet Sluggard, and twenty times as long again to reach the star we have established to be nearest."

"Hah! If means were given me, I'd do it! I'd spin a rope of spuder-web and catch the moon, and swarm up it to see what's going on out there! But since we can't, I must be content with my current project. You see, although you may view the rise in water-level as an unmitigated disaster, I say we shall be amply repaid by the recovery of some of our ancient lands. Already at the fringe of melting glaciers we have found frozen seeds, wingets, animal-hides and mandibles, even tools belonging to our remote ancestors. This year I purpose to venture further north than anyone since the Freeze began. It's an ideal time. So far this season we haven't seen a single berg in these latitudes. What's more, there have been many fewer storms than formerly—to my surprise, I might add, because if the sun is heating up I'd expect the air to roil like water meeting hot rock ... Yockerbow, I detect a hint of wistful envy."

Yockerbow gave an embarrassed shrug. It was true he had been dreaming for a moment, picturing to himself the new lands Barratong described.

"Come with me, then," the admiral said. "The Fleet has the ancient right to select a hostage from among the people of Ripar, exchanged against one of our own as a gage of amity. This time I choose you. And we already know your spouse fancies a sea-voyage; she may come also."

"But—!" Iddromane burst out.

"But what?"

"But he is our most notable inventor!"

"That's exactly why I picked him; he has the sort of open mind which permits him to see what happens, not what one might expect to happen. If you refuse, it will be a breach of our long-standing treaty, and you need not count on us when the tune comes—it will, I promise you!—when your folk find you can neither stay here nor flee inland, and require my Fleet to help in your removal to safe high ground! But in any case it will be only for this season, unless Yockerbow decides to opt for a life at sea. It has been known for people to make such a choice ... Well, Yockerbow?"

There was one sole answer he could give. All his life he had been led to believe that sea-commanders were no more than traders, glorified counterparts of the subtle, greedy folk who thronged the Ripar docks, Barratong, though, was none such. He was a visionary, who shared the passion that drove Yockerbow himself, the lure of speculation, the hunger for proof, the delight to be found in creating something from imagined principles which never was before on land or sea.

How much of this came logically to him, and how much was due to Barratong's odor of dominance, he could not tell. He knew only that his weather-sense predicted storms if he did not accede.

"Arranth and I," he declared boldly, "would count it a privilege to travel with you."

There was a dead pause during which Arranth looked as though she was regretting this fulfillment of her juvenile ambition, but pride forbade her to say so.

"Then there's nothing more to be said," grumbled Iddromane, and signaled his musicians to play louder.

V

Yockerbow and Arranth were not the only new recruits to depart with the Fleet. Here, as at every city the junqs had visited since Barratong assumed command, scores of other people—mainly young—had decided that life at home was too dull for them, and they would rather risk the unknown dangers of the sea than endure the predictable monotony of Ripar.

Seventeen of them had survived interrogation by Barratong's deputies, and the peers were not averse to letting them go; the city's population was beginning to strain its resources, so they did not insist on an equal exchange.

Dawn of the fifth day saw the junqs turn outward-bound again—vibrating with hunger by now, yet perfectly drilled. Sedate, majestic, they adopted an echelon formation such that when they came on schools of fish or floating weed there would always be at least a little left even for the younglings that held the rearmost station. Thus impeccably aligned, they beat their way north.

"Is this like what you were expecting?" Yockerbow murmured to Arranth as they clung to the haodah of the banner junq and wondered how long it would be before they could imitate the unfeigned self-confidence of the children who casually disregarded the motion of the waves.

"Not at all!" she moaned. "And I persuaded Iddromane to let me have a first-rate telescope, too, thinking I might make useful observations! How can one study stars from such a fluctuating platform?"

The greatest shock of all, however, was to follow. Who could have guessed that the admiral of the Great Fleet of the Eastern Sea was bored and lonely?

Oh, bored perhaps. After one's sub-commanders had flawlessly executed every maneuver required of them for half a lifetime—after putting in at ports of call on every shore of the world's largest ocean—after dealing with people of different cultures, languages and customs for so long—yes, one would expect him to lose the sharpness of his prong. Yet ... lonely? When volunteers flocked to join him at every stopover, and even in mid-ocean, as was shortly manifest when the Fleet was accosted by fish-hunters risking their own lives and those of their barqs, only to be turned back to shore disappointed? No, it was incredible!

Nonetheless, it proved to be the case. Yockerbow found out the second dark of the voyage, when chief navigator Ulgrim—amused, apparently, to meet not only a landsider but a female with at least a smidgin of skylore—had taken Arranth to the stern for a practical discussion. It was a fine clear night, with little wind, and only a clawful of falling stars. The Great Branch gleamed in all its magnificence, and the Smoke of the New Star was clearly discernible, at least as bright as the glowvines of a city they were passing to the westward. The glowvines on the junqs themselves were shielded, for fear of attracting hawqs or yowls; they were rarely fully exposed, as Yockerbow had been told, except when approaching shore or when the fleet needed to keep in contact during a gale.

And there was Yockerbow, more from courtesy than choice, alone with Barratong at the prow, while the rest of the crew amused themselves with a game that involved casting lots.

"Chance..." the admiral mused, making obvious reference to the gamesters. "Well, one can see why people tossed on the ocean by a life-tune of storms may hew to notions such as luck, but—You, Master Inventor! Do you believe your great achievements were the fruit of accident?"

Cautiously, for the "great achievements" were far behind, Barratong having concluded that his pumps could not easily be adapted for use on a junq, Yockerbow answered, "I think luck must be a different phenomenon from chance. I think the world goes about its own business, and those who are ripe to respond do so, much as a fertile plant catches the spores of its kin from a favorable breeze."

"Diplomatic as ever!" said the admiral sourly. "How I wish you'd speak your mind openly! If you only knew how I hunger for someone who might amaze me—startle me by voicing one of my own ideas without being prompted! Better yet, mention something I never dreamed of even when I was half-starved as a youth, plodding from city to city in search of knowledge and instruction!"

"Is that how you began your career?" Yockerbow ventured.

"What else but the quest for knowledge would tempt a sane person away from a comfortable home? What else would persuade a landsider to take to the ocean, except the chance of getting to meet more strangers in a shorter time? Oh, I've sat with scholars in a score of famous cities, listening eagerly to what they purported to teach the world, and after a few years I realized: no one is making new discoveries any more! My sub-commanders long refused to visit Ripar, because last time the Fleet came so far north the junqs were set on by a gulletfish following the drift of the bergs, and two were lost. I acceded for a while, until I heard rumors about the Order of the Jingfired, and even then I held back until reports of your pumps reached me. I never expected them to be useful aboard a junq, but it was an excuse to swing the support of other commanders behind me. Then the absence of bergs during our trip this year came to my aid, and now they are agreed that if I've been successful so far the chances are good that I'll continue to be so. Myself, I can't but doubt it. And I have no one I can turn to for sane counsel."

The last words were added in so low a tone that at first Yockerbow was unsure whether to reply. At length he made his mind up.

"Admiral, I recognize you for a visionary. Such folk have always encountered difficulties. In my humble way, I've done the same. But—well, since it wasn't truly news of my inventions which drew you to Ripar, I deduce it was the hope that the Order of the Jingfired possessed data that you lacked."

"Was I to know there would be a vacancy in the Order when I chose to turn up? The decision to head north this year was already taken."

"Then"—boldly—"how did you plan to obtain the Order's secrets?"

There was a long interval during which one of the outlying scouts reported a huge float of qrill, and the entire Fleet altered course fractionally to take advantage of it. When Barratong replied, there were loud squelching noises in the banner junq's maw, and now and then the whole of her body rippled longitudinally and let go a puff of foul-smelling gas.

"Had I not been inducted to the Order," the admiral said at last as though the interruption had not happened, "I did plan to choose Iddromane as my hostage for this voyage, or some other scholar well grounded in the so-called 'secrets' of the Order. I'd have relied on his terror during the first storm we met to make him reveal—"

Pride in his own city made Yockerbow risk breaking in. "It wouldn't have worked!"

"It wouldn't have been worth it," Barratong retorted sourly.

Yockerbow was shaken. "You mean there's nothing worth knowing in what they teach you?"

"I wouldn't say nothing," came the judicious answer. "I do accept that, acting as they do to preserve lore garnered in the far past, they have succeeded in assuring the transfer from generation to generation of certain indispensable facts. Of those you meet on the branchways of Ripar, or Grench or Clophical, come to that, or any city, or even as you pass from junq to junq of the Great Fleet, how many folk would you rely on finding whom you could talk to about what really matters—the nature of the universe, the fires of heaven and how they correspond with those down here, the beginning and the end of everything? Hmm? Many would be prepared to debate with you on any such subject, but how few would have solid evidence to back their views!"

"I always thought," Yockerbow admitted, "the Order of the Jingfired did have evidence."

"They claim to have, but when you ask for it, it can't be produced!" Barratong exclaimed. "I'm ready to believe, for instance, that long ago one of the stars in the sky blazed up until it outshone the sun. I can see the cloud of glowing gas they still call its Smoke—it's right there, isn't it? What I want to know, though, is why that happened, and why it hasn't happened since! And then there are elderly folk among my own people who say that when they were budded certain stars were not so bright as they are now ... but who's to define what 'bright' means? Can the members of your Order tell me that? They swear in principle they could—if only they had certain ancient star-maps which were spoiled by a flood! But when I asked for them they hadn't even kept fragments and tatters which I could have shown to Ulgrim!"

He concluded that tirade on a fierce tone, and a second later continued in a much milder voice, as though reminded about Arranth by his reference to his chief navigator.

"They said at Ripar that your buds don't take."

Yockerbow curled his mantle before he could stop himself, and a waft of combat-stink fouled the salty air. Aghast at his bad manners, he was on the point of prostrating himself when he realized that the remark had been made in the matter-of-fact fashion of an equal speaking to an equal. Flattered, he confirmed its truth.

"Nor do mine," said Barratong, staring across the water where the new-risen moon was creating a path of brightness for others to follow— not the Fleet. "Your lady wishes me to join with her, and I shall with pleasure, but don't expect the offspring you can't give her. Were I capable, my line would be among the greatest in history. But the only thing that keeps the Fleet in being—the only thing that helps so many cities to survive around the shores of the eastern ocean—is the fact that a first-time mating between strangers takes more often than not, so your seventeen from Ripar will engender enough progeny to keep us going for quite some while ... Oh, Yockerbow, I almost look forward to the tumult the great melting will entail! We must stir the folk around more! Little by little, thanks to our habit of choosing either sea or land, either drom or junq, either this or that, we are breeding apart! And the same holds for the inventions made in one place or another! Do you know about the longwayspeakers that they have at Grench? No? I thought not. But think what use you could have made at Ripar of a means to communicate simply by beating on a distended bladder in a patterned code, comprehensible to somebody the other side of a mountain range: they can do that! And they can signal orders at Clophical by using trained and brightly colored wingets which make patterns that are visible from end to end of the valley, but they don't survive being taken out to sea. And the use they could make of your pumps at Gowg...! Do you see what I mean?"

Yockerbow certainly did, but already he was lost in contemplation of the possibilities. He stood silent for a long while, until Barratong roused him with a nudge, pointing to the north.

"Look yonder! What can the Jingfired tell me about that—hmm?"

For an instant Yockerbow thought he must be watching a drift of cloudcrawlers on their migration route; some species displayed bright flashes from time to time, and occasionally they synchronized to make bright polychrome bands. But this was much too blue, and too near the horizon, and anyway the season was wrong.

"Tonight the sky is clearer than I ever saw it," said Barratong. "You're looking at the aurora round the pole. I've been told that when one draws close enough it reaches to the apex of the sky. Not that anyone has seen it in all its glory since the Northern Freeze—but on this trip we shall! Even my sub-commanders don't know what I have in mind, friend Yockerbow, but on this voyage I mean to break all records for a northern swim, and go where nobody has dared to venture since the ice claimed what was habitable land. I want to witness the rebudding of the continents! Don't you?"

VI

After a few days of steady northward travel, they made the first of many detours. Fog and mist did not deceive the northfinders carried by the Fleet, but this tune a violent storm lay across their course. At about the same tune the sea became noticeably cooler, as though chilled by melting ice. Paradoxically, however, at the same time it started to teem with a wider range of life-forms than could be found in the waters nearer Ripar, from the tiniest qrill which Barratong scooped up in a shell and showed to Yockerbow through a single-lensed microscope that magnified better than ten-score tunes, up to giant schools of sharq. The Fleet accorded these a respectfully wide berth also, not because they were a threat themselves, but because they in turn were hunted by the fiercest predator in these waters, the huge and solitary gulletfish whose mindless charge could rupture the tubules of even the largest junq. For amusement, elderly mariners jelled the ichor of the new recruits by regaling them with tales of what it was like to meet a gulletfish in mid-ocean and try to make it charge a barbed prong. It was worst in the dark, they said, when all one had to guide the eye was the ripple of phosphorescence as it rounded to for yet another onslaught.

"How rich in life the planet is!" murmured Yockerbow, and Barratong gave him a sardonic dip.

"Who says only this planet? Some think the stars may be alive, or harbor life, because living creatures are always warmer than their environment! Myself, though, I suspect the reason we don't find such a plethora of fish in tropical waters is that life requires a differential of heat, the way your pumps require a differential of level, and as the water becomes warmer the task of survival grows harder, just as when it grows extremely cold. What about that?"

Yockerbow felt he would never grow accustomed to the way the admiral kept tossing out provocative ideas, even though he was modest about the source of them, and always gave credit to anonymous scholars said to have been met in distant places. By this time, however, Yockerbow was beginning to doubt their existence. Barratong combined his restless genius with a diffidence more proper to a shy young apprentice.

He said after a pause for thought, "It makes sense to invoke a limit at either end of any scale of events. Just as there is no life in solid ice, so there is probably none in the stars. After all, a living creature which is trapped in wildfire dies, and certain persons have conducted experiments wherein a small animal and some burning fuel were closed up together, and the animal died and the fuel did not burn out."

"I've heard of such cruelty," Barratong said musingly. "I personally would not care to witness it, but I'm glad in a sense that someone could bear to ... Ah, there is so much to know, my friend! And so much that has already been discovered in one place, yet never conveyed to another! But we have spoken of such matters already."

"As we have," rumbled Ulgrim, approaching from the stern with Arranth—somehow shyly—following him. "Admiral, do we plan to put in at any harbors before we reach the polar circle? The lady has convinced me that it would be of interest were I to peek through her big spyglass on stable ground."

Behind his back Arranth gave a moue, as to tell Yockerbow, "See? There are some who respect my learning even if you don't!"

Whether Barratong noticed or not, he gave no sign. He merely chaffed Ulgrim, who was still tall but whose mantle showed the tell-tale wrinklings of age.

"What youth and good looks may do to reform a character! You never cared to come ashore with me in other climes to hear what the local philosophers had to say, or view their instruments and their experiments! Lady Arranth, I bow to you; whatever else you may be schooled in, you certainly display a vast knowledge of people's nature! But the answer's no!"

Abruptly he extended to his maximum height, a third or more above his usual stature, and even though this brought him barely equal with Yockerbow and Ulgrim, the effect was as shocking as though he had grown taller than mythical Jing. One more element was added to Yockerbow's understanding of this admiral's dominance over his enormous Fleet.

"We go ashore next time on land newly exposed by the retreating ice! We stocked the junqs with food enough to see us through the trip—their drink-bladders are bulging—no blight or mold afflicts the food-plants— and we have medicines for every conceivable ill! For all I know, the landfall we next make may be shrouded under so much cloud you can't see stars—but never mind! We already know how the ice when it melts reveals wonders from far distant in time, so the wonders that are distant in space may take care of themselves for this season! The stars are slow to bloom and fade, but you and I are not. Time enough for your observations next whiter, if the Fleet remains in the far north and we are compelled to he up a while, which I suspect ... But tell me, though, old companion"—this as he imperceptibly resumed his normal pressure— "what's excited you anew about the stars you've known so well for so long?"

Embarrassed, but putting a bold countenance on matters, Ulgrim said bluffly, "She speaks of stars which I can't see, and yet they're there. More than once since leaving Ripar, when the water was most calm, I've thought I could discern them—an eleventh in the cluster of the Half-Score Wingets, another at the focus of the Welkin City ... And of such a color, too: a strange deep red! Yet when I look again—!"

"Master Navigator," Yockerbow said, "have you ever seen a bar of metal heated in a fire until it melts?"

"I never had time for such landsiders' tricks!"

"I know: one dare not carry or use fire aboard a junq. Yet fact is fact. The metal starts to glow in the dark red; afterwards it becomes orange, and yellow, and green—which we see clearest—and then shades through blue to white, just like the rainbow. Eventually it can be made to glow like the sun itself. It follows that a hotter or a cooler star..."

His words trailed away, for Barratong was scowling.

"I thought you were never inducted to the Order of the Jingfired!" he said in an accusatory tone. v "What does that have to do with it?" Arranth demanded before Yockerbow could reply. "Had I but the means, I'd show you all this with a glass prism!"

"It is as I feared!" Barratong raged, and began to pace back and forth along the poop of the haodah, spuming at every turn so violently one thought he might blister his pads. "Your vaunted Order possesses no truly secret knowledge! Do you realize that the heating of a metal bar is the chief symbol of their most private ritual?"

There was a moment of dead silence, save for the slap-and-hush of waves against the junq's broad flank and the meep-meep of a flighter and its young which were following the Fleet in hope of scavenging carrion or floating dung.

All of a sudden Yockerbow started to laugh. As soon as he could he recovered his voice and said, "Admiral—excuse me, because this is truly too silly—but you were right the first time, and this time you're wrong. It doesn't matter that someone else knows the inmost secret of the Jingfired ritual. What counts is that Ulgrim didn't."

"I think I see what you mean," said Barratong, and a waft of anger-stink blew away as he mastered himself. "Clarify!"

"How long ago was such a truth discovered, that may prove to be valid even in the case of the stars? Well before the Northern Freeze, we may be sure! What happened following the onset of it? Why, people driven crazy by hunger and despair felled great civilizations which otherwise might well by now have shown us things we regard as impossible—you might, for instance, have your spuder-web to catch the moon! But nobody among the Fleet would dare to undertake the necessary research because a fire literally cannot be lighted on a junq! Hence no metal—no glass—no melted rocks—no anything of the kind which pertains to such realities!"

He was downwind of Barratong as the Fleet bore into a strong northerly breeze. Whether it was because he scented the admiral's enthusiasm, or because the newly exposed lands which the ice had reluctantly let go were emanating signals from those who had once occupied them, he never knew. But in that moment he was as great a visionary as the admiral.

"Yet we can bring our knowledge all together!" he declared, and his weather-sense confirmed that he had safely picked a course into imagination, steering well clear of dangerous dreamness. "Knowledge borrowed from past time will guide us to the future we deserve for all the troubles we've endured! There must be suffering—would I knew why! I don't believe the stars decree it, for they're so remote they might as well be cool and stiff like arctic rocks, yet they can blaze up, and I don't want to think it's simply because they suck into themselves the vital force from planets like ours where life exists between the limits set by ice and fire!"

"Say it's because of ignorance," offered Ulgrim, and at once looked surprised at his own improbably philosophical suggestion.

"Yes! Yes!"—from Barratong. "Have we not found remains of animals such as none of us had seen or heard of? Have we not then encountered similar beasts in strange new waters? And are we ourselves not different from our ancestors? It follows that if the stars blaze up it must be for a reason we shan't comprehend until we work out why there are creatures—or were—unknown to us on this small planet!"

"We understand each other," Yockerbow said soberly. "I was so afraid when you invited us to come with you..."

"Ah, but we're all bound on one quest," Barratong stabbed. "Some of us seek an answer to a single mystery—you, Yockerbow! You wanted to find out why syphonids and cutinates could never pump water above a certain level. On the way to a solution, you saved your city from being washed away. You still don't know all the reasons why the original phenomenon presented, but you have suspicions, don't you? And Arranth has just drawn my dear old partner whom I've trusted in storm and floe-time, trusted under the onslaught of heaven's crashing meteorites— drawn him too by some miracle into the charmed circle where I hoped to lure him long ago" (this with a dip to her) "and for that I thank you, ma'am—"

Yockerbow was half-afraid the admiral had lost track of his own peroration, but he was wrong, for he concluded it magnificently.

"And here we are together on the sole straight course which any of our people ought to choose! All of us a little angry with the universe because it seems to want to mislead us—all of us determined to find an answer to at least one mystery before our time runs out—all of us resigned to the certainty that we shall uncover many other mysteries in the solving of our own! Perhaps the time may come when there are no more questions to be asked; if that is so, that's when the world will end!"

VII

Cooler it became, and cooler ... yet not cold. No frost-rime formed this season on the rigging of the haodahs, and the junqs themselves responded briskly to the increasing iciness of the water, as though they needed by activity to keep the ichor coursing in their tubules. Awed, those who rode them as they trespassed among bergs and floes under an amazing pale blue sky watched the bare brown land on either side slip by, and marked where it was suddenly not bare, as though the sun had charmed plants out of rock.

"We are approaching the polar circle," Barratong said. "We are the first to come by sea in who can say how long? But we are not the first of all. See how the flighters whirl who brought new life to these mud-flats!"

Watching their graceful swoops, as they glided back and forth and sometimes failed of their prey so they had to whip the water and achieve enough velocity to take off again, Yockerbow said, "How can they eat enough to fly?"

"Sometimes," said Barratong, "they can't, or so I was informed by a fisherman whom we rescued in mid-ocean the summer before last. They breed on high bluffs and launch their offspring into air by laqs at a tune when they burst the brood-sac. Those which catch enough wingets and flyspores grow; they soar and mate on the upgusts; then they hunger for what's in the water, and if they're large and fast enough they snatch the surface-breeding fish. If not—well, they can use up what fat they've stored and spring back into air from the crest of a rising wave. But this fish-hunter had many times trapped those which did so, and always found them lean and scant and taint of flesh. It's my view that flighters' natural zone is the air; by contact with either land—except to breed—or sea, they are diminished of their powers. Witness the fact that out of every brood-sac a score or two survive. And is not the same phenomenon apparent in ourselves? Had you and I, and all the other so-called worthy persons, bred at every pairing, would we not by now by laqs and craws have overswarmed the pitiful resources of the Age of Freeze? How many more of the folk could Ripar have supported before either they started to starve off into dreamness or some epidemic sickness rushed through them like a flame in dry brushwood? Hmm?"

Yockerbow, after a second's pause, admitted, "It is in the records of the city that Ripar came close to that."

"As did our Fleet," the admiral rasped. "How think you I—a landsider—was able to assume command? I was better fed than old Grufflank, and that's all! He dreamed away his days in nonsense visions! There was I fit and strong and offering suggestions so practical the captains' meet recognized the common sense of them. Yet, given a season's decent diet, any of them might have done the same, and more, for they had sea-experience, while I did not..."

He brooded for a moment; then he concluded, "At least I can say this. I'm still in the domain of imagination and not dreamness; my weather-sense assures me of it, and that's the sense that fails us last, even though the eye or the very mantle may be fooled. A sweet taste may deceive you; a fair odor; a sleek touch ... but weather-sense extends into your very pith and being, and even if you starve it's last to go. Moreover it's what leads us to trust out junqs more than ourselves. At Ripar, do they know the legend of Skilluck?"

Yockerbow looked blank, but to his surprise Arranth, standing by as usual but less bashfully than before, said, "If the name is Skilq, we have the same tale, probably."

"Who swam a wild briq across the western ocean when all others had lost their way, and salvaged something of a now-lost city?" Barratong rounded on her with excitement.

"They say he saved the telescope for us," Arranth concurred. "All younglings at Ripar are told the story."

Having dismissed fables of that sort from his conscious mind because his preceptors so ordered him when he entered into adult phase, Yockerbow was acutely embarrassed. He said, "I too of course heard such stories, but in the absence of evidence—"

"To starfire with your ideas of evidence!" roared Barratong. "For me, it's enough that someone in the Fleet should remember hearing a vague tale! It's because I want to turn the legends of the past into a new reality that we are here! Those which don't stand up to present discoveries may be dismissed as spawn of dreams! But anything I take in claw and hold and use—!"

He broke off, panting hard, because he had involuntarily tallened again. Relaxing, he concluded in a milder tone, "Besides if the same tales survive on land as we know among the People of the Sea, there's a double chance of them being based on fact. Do inland folk recount the stories, too? If so, are they just borrowed from contact with mariners?"

The ebb and flow of talk surrounding Barratong was such as Yockerbow had never dreamed of. Once he dared to ask what mix of ancestry had given him rise, and met with a curt—though plainly honest—answer.

"I inquired about that, right up until I found I was a muke, and got no details; there was a famine which affected memory. And after I discovered that my line won't take, there seemed no point in pursuing the matter. I can only suggest and instruct; I cannot breed."

Timidly Yockerbow ventured, "A—a—what did you call yourself?"

"A muke! Take junqs from a northern and a southern herd, and they will mate eagerly enough, and often throw a bunch of first-class younglings. Yet when you try to make the strain continue, it's like me, and you, and—given she's tried me and Ulgrim and a score of others in the Fleet—Arranth as well. We call those mukes, and hope against hope the wild strains will continue to furnish us with the next generation..."

With an abrupt shrug of excitement, he added, "Yet there is hope! Suppose our heritage has lain under a mantle of impotence as the northern continent lay under ice: the end of the Northern Freeze may signal salvation for us mukes! I couldn't begin to tell you why I foresee this; it may be leaked from dreamness to my mind. Still, the border between dreams and imagination might very well fluctuate just as the boundary between ice and ocean does ... Oh, time will judge. Now watch the way the land is changing on this coast. Look not just for the flighters that bore back southern seeds when they quested their prey into these waters, because as you know some seeds pass clear through the digestion of a flighter and are nourished by the dung they're dropped in, nor for what they brought when it foliates and blossoms, but for what lay hid till now when the sun came back and released it ... Ah, but darkness falls. Tomorrow, though—!"

And he was right. He was astonishingly right. Next dawn revealed what he predicted, and Yockerbow decided—though he could not convince Arranth he was correct in saying so—that among Barratong's chief gifts must be the art of assessing whether someone who relayed a story to him told the truth.

For their course came to a dead end in a wide bay whose northern shores were still blocked off by a huge glacier. Some drifts of mist hung about it, but it was a fine morning and a brisk wind disposed of most of them within an hour.

And, either side of the steep bluish mass of ice, life was returning. Not only were the drab gray sand-slopes nearby aweb with creepers and punctuate with burrowers: the air was full of unexpected wingets. The mariners caught as many as they could, for some were known to lay maggors which infested junqs, and brought them to Barratong for examination.

"They're unlike any in the south," he stated. "Even if they are similar, then the colors vary, or the size, or the limb-structure. Is the Fleet still thriving?"

"As ever!" came the enthusiastic report. "We didn't expect to fare so well this far north, but the junqs' maws are crammed and we ourselves enjoy the food we reap from the sea!"

"Then here's our landfall, and our harvest will be knowledge!" cried the admiral. "Report to me whatever you find unusual—"

Something shot past him with a whizzing sound. A moment later, Ulgrim, who stood nearby, cursed and clapped a claw to his upper mantle. Withdrawing it, he displayed a pointed object with a pair of vanes on the after end. Similar noises continued, and complaints resounded from all the nearby junqs.

"What in the world—?" began Yockerbow, but Arranth cut him short.

"Those must be seeds!" she exclaimed. "Did you never play the game we did as younglings—placing seeds like those on a rock and shining sunlight on them through a burning-glass until they flew away?"

Once again Yockerbow found himself at an embarrassing loss. When he was a youngling, he had known nothing of such miracles as lenses, or indeed any form of glass. Attempting to recoup his pressure, he said, "You mean heat bursts them?"

"Burst? Not in the sense a bladder bursts, dear me! They emit some sort of stinking gas from one end, and that makes them leap through the air."

All this time, a horde of the things was descending on them, and Barratong—who else?—was reasoning about the strange phenomenon.

"They must be coining from up there," he said, and pointed to a bluff a little above their own level, where a dark shadow was growing more and more visible as ice melted and water cascaded down the lower rocks. "That's where we'll send explorers first. A sign of life is never to be overlooked."

"And the top of that bluff," said Arranth in high excitement, "would be just right to set up the telescope I brought! That is," she added hastily, "if the dark-time is as clear as this morning, and weather-sense indicates it may be."

Exuding an aura of puzzlement, Barratong said, "I fear you're right."

"Fear?"—from two or three voices simultaneously.

"Our whole voyage has been strange," the admiral said after a brief hesitation. "Too fair weather—no storms to mention—the bergs dissolving as we passed by ... There is a real change taking place in the world, and it disturbs me. We must seize our chance, though! Overside with you!"

The Fleet having been instructed to make all secure, a small group of crewmen was detailed to follow Ulgrim and find a way to the cliff-top where the telescope might be sited. Meantime Barratong, Yockerbow, and Arranth, who was too impatient to concern herself with preparatory details, set off along a sloping miniature watercourse towards the source of the flying seeds. Its bed was pebbly, and the flow chilled their pads, but they were able to obtain a good grip on the gradient, and shortly they found themselves looking at a shadow behind a veil of ice.

"Now there's a cave!" declaimed the admiral, loudly enough to overcome the rushing of streamlets which was greeting the advent of renewed summer. (Had there been one last year? It seemed unlikely; Yockerbow was prepared to believe that Barratong's weather-sense had picked the very first possible year for folk to return to these latitudes.) "What icefaw or what snowbelong may have laired here! What refuge it may have offered to beasts we exterminated when the Freeze drove them southward! You realize, of course"—lapsing into his most condescending and didactic mode—"that up here there may still be creatures which cannot live off vegetation but devour other animals, as sharqs eat other fish?"

For once the others paid him no attention. They were seeking the source of the flying seeds, and shortly found it: an ice-free patch was exposed to sunlight on the side of the adjacent rock, and a small, tough, low-growing plant was exerting its utmost efforts to reproduce itself, though by this time its main arsenal had been expended and only a few weak flutterings resulted.

Standing back, Arranth began, "I think—"

"Look out!" Yockerbow roared, and dived forward to push her clear of impending disaster.

Whether it was the effect of sunshine, or whether—as they later wondered—the mere vibration of their presence sufficed, the ice-veil before the cave was starting to collapse. A web of cracks appeared; a grinding sound followed...

"Down!" roared Barratong, and set the example as great frozen shards fell crunching and slid down the watercourse. They clutched at what they could, including one another, and somehow succeeded in not being carried bodily away.

And got uncertainly to their pads again, for nothing worse emerged from the cave than a most appalling and revolting stench, as of corpses shut up for uncountable years.

It blew away, and they were able once again to venture close, while the low northern sun beamed on them from a clear blue sky. At the cave-mouth things glistened wetly, and a few were instantly identifiable.

"There's a mandible," Barratong muttered, kicking it. "People too were here, you see?"

"Where there were people, I look for what people make!" shouted Arranth, and began to scrabble among the dirt at the opening. And checked, and said something incomprehensible, and rose, clutching a long rigid cylinder such as no creature in the world had generated naturally.

"It's a glass!" she cried. "It's a glass tube! And I hear something rattling inside!"

She made as though to crunch the crackly-dry wax that closed the tube's ends, but Barratong checked her.

"Not here! Whatever's in it must be fragile, for it's certainly very ancient. We'll take it back to the junq and open it with great care in a safe place. Are there any other relics like it?"

Reaching for the mandible, he used it as a scraper, and the others joined him in sifting through the foul mass of putrid matter at the cave entrance. Shortly they were satisfied there was nothing else as durable as the glass tube, and returned on board.

There, quaking with excitement, Arranth broke the wax and removed a stopper made of spongy plant-pith. Tilting the tube, she shook from it a tightly rolled bundle of documents, inscribed on an unfamiliar off-white bark. The moment she unrolled the first of them, she exclaimed at the top of her voice.

"I can't believe it! It's a star-map!"

"Are you certain?" Yockerbow ventured.

"Of course I'm certain!" Studying it feverishly, she went on, "And either it's inaccurate, or ... No, it can't be! It shows the stars as they were before the Freeze, and straight away I can assure you: some of the constellations aren't the same!"

VIII

The past can communicate with us...

Echoes of Arranth's repeated argument kept ringing through Yockerbow's mind as he and Barratong, and the senior Fleet sub-commanders, gathered to hear the result of her and Ulgrim's researches. In spite of aurorae and shooting stars they had been pursued through every dark-time until now, when their weather-sense warned of an approaching storm and indeed clouds could be seen gathering at the southern horizon. Every junq had been ransacked for writing-materials, and meticulous sketches were piled before Arranth, each adjacent to one of the pre-Freeze maps. Yockerbow shivered when he thought of their tremendous age. Yet they had been perfectly preserved in their airtight container.

Delighted to be the center of attention, Arranth could not resist preening a little, but when Barratong invited her to present her report, she spoke in a clear and businesslike manner.

"With only a single telescope and what crude instruments we could improvise, Ulgrim and I have not been able to make the sort of exact measurements that could be performed at a proper observatory. However, that is paradoxically fortunate. Whoever compiled these ancient maps can have had access to a telescope barely better than our own, if at all, so we have an excellent basis for comparison. In other words, we can be reasonably sure that the stars we see and those depicted on the old maps correspond. Thoughtfully enough, the map-maker indicated which stars were visible to the unaided eye, and which only with the aid of a glass. We have therefore been able to establish the following facts.

"First: the stars do change position—very slowly, but unmistakably— and some have certainly grown brighter.

"Second: there are not just a few but many stars now discernible which were not known to the map-maker, and all of them have something most disconcerting in common. They are all deep red, and they all he in the same general area of the sky. Which leads me to the third point.

"What we have been accustomed to call the Smoke of the New Star can be nothing of the sort. We have traced the site of the New Star, which in the days when these old maps were prepared was still clearly visible, though now it takes a strong glass to detect it. Indeed, one does not so much see the star itself, as a faint and wispy cloud of glowing gas with a dot at its center. But this is not the large, widespread cloud we normally think of. It's too far away—several degrees distant. On the other claw, within it there are some genuinely new stars, which must be far newer than that fabled one which burst out without warning and became brighter than the sun, as the old legends claim—though, strangely, no reference is made to heat from it.

"Within the Smoke, as I was saying, we have counted no fewer than ten stars of which there is no sign on the old maps. Moreover, what reference is made to the Smoke is cursory and vague, and no outline is indicated for it, though we can see one fairly clearly. All these ten new stars, what's more, are reddish, even darker than the Smoke, as though they only recently lighted their fires. They are barely bright enough to make the surrounding cloud shine by reflection, and much too far away to account for the ending of the Freeze.

"And even that is not the most astonishing news."

Having helped as best they could with the observations, Yockerbow and Barratong were primed for the final revelation, and glanced covertly around to see what impact it would have on the unforewarned.

Using an image which Barratong himself had supplied, Arranth said, "Imagine the Great Fleet keeping station on a calm sea, and yourselves aboard a solitary junq making haste towards it. Would you not see the nearest of the Fleet diverge to either side as you drew close, while the furthest remained at roughly the same angle?"

Puzzled at being reminded of something that everybody knew, her listeners signified comprehension.

"What disturbs and even frightens me," concluded Arranth, "is that scores of stars whose positions we can check against the old maps appear to have diverged outward from a common center, and that center is located in or near the Smoke. Either we, with the sun and all its planets, are hurtling in that direction, or the Smoke and its associated stars are rushing towards us. It makes no difference which way you look at it; the outcome is the same. And if, as certain astronomers believe, stars begin because they accumulate surrounding matter, be it whole wandering planets or mere dust like what comes to us as meteorites and comets, then there must be incredible quantities of it in any zone where ten new stars have started to burn since these maps were drawn!"

As though to emphasize her words, a meteor brilliant enough to shine through the daytime sky slashed across the zenith, and immediately thereafter Barratong cried, "Get those maps under cover! The storm will be upon us any moment!"

An echo of thunder confirmed his warning, and they scattered, the sub-commanders to their respective junqs, Arranth, Ulgrim, Yockerbow and Barratong to huddle beneath the shelter offered by their own's haodah.

Tucking the precious maps carefully into the tube again, Arranth said, "Do you think they understood?"

"Most of my fellow-navigators," Ulgrim grunted, "have never thought about stars except to figure out what use they are in guiding us, and most of our lives that hasn't been much, you know. The admiral's right: a real change is working in the world. This is more the sort of weather I'd have expected here in the far north, not the clear bright land we've had since our arrival."

The first assault of rain rattled the canopy of interwoven reeds that formed the haodah's upper deck, and the junq stirred restlessly as the air-pressure changed.

"Will the fine weather return?" asked Arranth.

Her question was mainly addressed to Ulgrim, but before he could answer Barratong cut in.

"It's over-soon to guess, but either way we must get these maps to where they'll be most useful. To begin with, I shall arrange to have them copied with the utmost care. I know who among the Fleet are most skillful at writing and drawing. Of course, I don't know whether we have enough writing-material left. But we'll do what we can, although we have to kill and flay one of the junqlings to make writing-sheets. Beyond that, though, there's the question of what we should do with the originals."

"Why, we take them back to Ripar, obviously!" Arranth burst out.

"It may seem obvious to you; it's not to me. They should go to the finest of modern observatories, and that's not at Ripar. Besides, Ripar is due to be flooded. Not all your spouse's pumps can save it—can they, Yockerbow?"

He made sober reply. "From the bluff where we've installed the telescope, we've seen ice stretching to the skyline. I wouldn't dare to calculate how far the level of the oceans will rise when it melts, but if it's going to be the same as before the Freeze, nothing can save Ripar or any other coastal city."

"Agreed. We should therefore present them to the observatory at Huzertol, inland from Grench and in a zone of clear skies." The admiral spoke in a tone of finality, not expecting to be contradicted.

"Won't do," said Ulgrim instantly.

"What?"

"Won't do," the navigator repeated. "Huzertol may have the best astronomers in the world, the best instruments—it doesn't matter. That far south, they can scarcely see the Smoke, and some of the other important stars nearby never clear its horizon."

Barratong gave a dry laugh. "You know something, old friend? Next year I think we ought to circumnavigate the globe, if only to impress on your admiral's awareness that we do live on a spherical planet! You're right, of course. We must find a northerly observatory."

"Or found one," said Yockerbow.

"Hmm! Go on!"

"Well, if there isn't any place in the northern hemisphere to outdo Huzertol, there ought to be. Ripar is wealthy, and Ripar is doomed. What better memorial than to create a city dedicated to learning and science on some suitable upland site, to which we could transfer—?"

But Barratong wasn't listening. Of a sudden, he was paying attention to the junq. Her back was rippling in a rhythmic pattern.

"The water's growing warmer," he said positively.

To Yockerbow, that seemed unsurprising, since the heavy rain must be raising its temperature. That, though, seemed not to be what the admiral meant.

A gong-signal boomed across the water. A pattern of banners, rain-limp but comprehensible, appeared at the prow of the junq lying furthest to the eastern side of the bay.

Barratong rose to his normal height as he stepped out from the haodah's protection. He said to Arranth, "Give me the map-tube!"

"What? I—"

"Give it to me! Bring cord to make a lashing and a bladder to wrap round it! There's no time to make a new wax seal!"

Ulgrim recognized the scent of authority before the rest of them, and scrambled to comply. While the others stared in astonishment, Barratong folded the tube with its maps inside a skin bag, and tied it tight with all his strength to the thickest of the haodah's multiple crossbars.

"Thus does the legend say Skilluck preserved his spyglass," he muttered, while the gong-signals multiplied and grew more frantic, and the junqs began to fret and buck. "And for the sake of imitating him, I'm risking the greatest fleet that ever was..."

The job was done. He turned back to them, claws clenched. "Now, Ulgrim, give the signal! Open sea!"

And the Fleet incontinently turned and fled.

The order came in tune, but only just. Wide though the bay-mouth was, the junqs jostled and tossed in their mad retreat, and the first huge slabs of the ice-wall were already sliding down as they escaped and their commanders regained control.

"Scatter!" Barratong yelled, and pounded the banner junq's gong. It could not be heard above the scraping, grinding, splashing noise from astern, and the rushing, pounding, battering racket of the new-budded waves that were smashing floes against the rocks. All of a sudden the world rocked and twisted and great hills of water erupted in their path, and sometimes the junqs ascended them at a giddying angle and came close to capsizing and sometimes they crashed into them prow-foremost so they broke and doused the crews and filled the back-wells, soaking the stored food. There was no need to order scattering; the alternative did not exist.

Out from the bay rushed bergs as keen as new-cut fangs, and the junqs panicked in their attempt to dodge. The haodah lashings creaked and the junqs screamed for pain, and some of the youngest sought to escape their burdens by rolling over, but their flotation bladders obliged them to right themselves, and if any riders were lost they were children and old folk too weak to cling on. Primeval reflexes bound the adults to whatever they could grasp, folding their mantles around to reinforce their claws and pressurizing the edges until they were stiff as stone.

In a moment of lucidity Yockerbow thought: Just so must Skilq, or Skilluck, or whoever, have endured that legendary storm...

Yet it was not the storm which had caused this. It went on pelting down, but it was trifling. No storm could make the ocean heave and seethe this way! Louder than thunder the noise of shattered ice conveyed the truth.

That warming of the water which Barratong had detected must have presaged the undermining of the high ice-wall. Once it collapsed, whatever was pent up behind it was turned loose, and the Fleet was washed away across the world as randomly as those vaned flying seeds...

IX

"Has it only been a year?" mourned Arranth, her mantle shrunken by salt and cresh, when next they came to what had been the site of Ripar. There was no more trace of the sea-defenses, no sign of the pumps Yockerbow had been so proud of—only some wilting treetops bending to the water, and a trapped mass of what had been prized personal possessions that washed back and forth, back and forth, in time to the waves. Any corpses must have been devoured long ago, for now a horde of greedy sharqs ruled where the Order of the Jingfired had held sway.

Not all the destruction, of course, had been caused by a simple rise in water-level. Maps and charts explained why Ripar had been worse affected than so many other cities they had visited. Northward, an archipelago had focused the impact of the first gigantic wave, driving it into a single channel where it could no longer spread out relatively harmlessly. Some of the islands had been completely washed away; enough, though, had resisted to ensure that Ripar's fragile protective banks dissolved under the eventual onslaught. Once the city's roots were exposed to the intense saltiness of the warm northern water—warm!—they were doomed.

But the melting was certain to continue, as was betokened by the presence of countless bergs following the same currents as the Fleet, and when—if—all the polar ice returned to the liquid state, the world would be transformed unrecognizably.

They had talked long and long about the future as they strove to recreate the Fleet. Barratong had had the foresight to decree what none of his predecessors had thought necessary: a rendezvous in mid-ocean, near four islands with fresh water and ample vegetation. That was where they had waited out the winter, but one of the islands was shrunk to half its normal size and many of the edible plants were dying ... as were too many of the reunited junqs. There was a loathsome taint in the air, and every gust of northern gale brought a drift of grittiness that revolted the maw and made the torso itch beneath the mantle. Sometimes the aurora towards the pole was blanked out not by regular clouds but by some kind of dust, not cleanly star-budded dust such as gave rise to meteors—few, come to that, had been seen this year, hidden no doubt by the same ghastly veil—instead, like the much-feared smoke which drifted from the world's rare drylands when a lightning-strike released wildfire, and could blind and choke those trapped downwind.

"But we saved something worth as much as any city," said Barratong, and pointed to the glass tube holding the old star-maps, which had miraculously resisted the worst the waves could do.

Embittered, Yockerbow as well as Arranth railed at him, and to all their complaining he responded imperturbably:

"You will die, and I, and all we can create—why not a city? But if there is one thing that deserves to be immortal, it is knowledge. Perhaps in the far future like my web to catch the moon a means will exist to unite past and present, here and there, abolishing distance and anxiety at a blow. We spoke a while back, though—did we not?—of an observatory, and a city we shall dedicate to science?"

"A while back" had been very nearly a full year, and Yockerbow, overcome with misery and privation, had long ago dismissed his proposal to the realms of fantasy. He was amazed to hear the admiral repeat it seriously.

"It's out of the question after a catastrophe on this scale," he muttered. "And it isn't over yet. It may take scores of years before the water-level stabilizes. If all the polar ice melts, there may be no dry land whatsoever."

"I don't believe it," Barratong responded. "But even if that's so, we shall build continents of floating weed! We'll not go tamely to an accidental doom! And if we can't learn about the stars, we'll learn about ourselves and the life around us!"

He drew himself up stern and tall, and now he did overtop his companions, for their dispirited mood had sorely shrunk them.

"This you must understand at least: we are the Jingfired now."

Eventually the implications of his words penetrated the dismal fog in Yockerbow's mind, and he too straightened. He said, "You intend it seriously?"

"Oh, not at once, of course. First we have other duties to attend to. I shall break up the Fleet, and dispatch it to every corner of the world, bearing seed and medicine and knowledge above all. At every port of call my commanders will be instructed to inquire after secure sites where people may remove to, and rescue whoever needs to be conveyed thither. Also they shall diligently search out scientists and scholars, so that when we choose the site for our new city—not this year, not next, perhaps not in our lifetime—our successors will know where to recruit a population for it. Then let them assemble with their books and instruments and do as you, friend Yockerbow, suggested: combine their knowledge so that none be lost."

"Will you be obeyed in this?" husked Arranth.

"Oh, I think pride will serve to persuade the ones I have in mind."

"Pride in independence, because they will be in command of their own Fleets, with the right to take wild junqlings and increase them?" Ulgrim's tone was cynical; for countless generations, it had been a punishable offense to do so.

"In part." Barratong was unperturbed. "More to the prong, however, pride in ancestry—which I, an ex-landsider, cannot boast of. Think, Ulgrim! Think of how the People of the Sea must already be reacting to the news that their forebears chose correctly! We face nothing worse than storms and tidal waves. If an island we're accustomed to put in at vanishes, we find another; if the waters rise and swamp what was dry land, so much the better, for where there were isthmi now we find new channels that will take us into undiscovered seas ... Oh, we shall be rulers of the western ocean too, and very soon! And will not it make for pride that we give aid to those who boasted of security on land?"

"You think more clearly and more distantly than anyone," said Ulgrim in a sober voice.

"Not I! Not I! But Arranth and her like. You chided me for not reacting to the fact the world is round! She saw the very stars moving apart like local floes!"

He gave a little crazy laugh. "That's why I must break up the greatest fleet that ever was. There aren't enough of us to fight the stars, and after this long melting we'll be fewer still. We need a score of Fleets, a score-of-scores! We have to be so crowded and so crammed together that we can burst outward from the world—become like these!"

From one of his baldrics he produced a tiny object, dry and shriveled.

"Remember these?"

"One of the seeds that pelted us up north," said Yockerbow.

"Correct! Well, if a mindless plant can find a way to spread beyond its isolated patch, why shouldn't we? Did it ever strike you that there must have been a first person who pithed a barq or briq, just as there was certainly a first who tamed a junq? Then, folk were confined to continents or islands, and had to trudge wearily from place to place unless they had a drom—and someone, equally, must have been first to ride a drom!"

Ulgrim and Yockerbow exchanged worried glances. Sometimes nowadays Barratong spoke so strangely ... Only Arranth seemed totally to understand him, as though he and she, during this dreadful winter, had found a skyward course into the future in their joint imaginations. But how sane was their shared vision, when the world itself was dissolving back into its primeval waters?

"I wish," said Yockerbow, scarcely realizing he had spoken audibly, "I'd never left Ripar. I'd rather have been here to tend my pumps, to learn their limitations and escape to high ground where I might have built them anew and much improved."

"Somebody will," said Arranth with assurance. "Now your task is to wander the world teaching those who need to know how it was done, just as mine is to explain the star-maps that—thanks to Barratong—have been preserved. You never respected the Order of the Jingfired, and you had some justification, I suppose, given that you devised new methods not envisaged by its ancient wisdom. But I always did, even when I was angry at the way intrigue and self-seeking tarnished its ideals. And if Barratong, who at first mocked it, has come around to my point of view—well!"

Acid rose in Yockerbow's maw. He was minded to utter cruel truths, for she had not truly respected the Order, only envied its members, wanted her spouse to be inducted for the glory of it. He meant to tax her with her ridiculous adoption of crossed strands of sparkleweed in imitation of an admiral's baldrics, seeking petty temporary fame by setting a trend.

Yet he could not. This last appalling year had altered her. The first signs had already been apparent when she spoke with such authority of the discoveries she had made with Ulgrim. Now she had grown used to being someone other than her old self. In a way not even she could have foreseen, she had fulfilled her ambition and become the admiral's lady.

Who was this new strange person who confidently claimed to understand the actions of the stars?

Not his spouse. Not anymore...

So leave her the luxury of self-deception, that she might the better convince the few who, like her and Barratong, could see beyond the current crisis. For his part, he had information about techniques that would be useful everywhere when folk settled on new lands and needed fresh water drawn from a distance, or irrigation systems, or means to lift a heavy load. Suppose, for instance, there were other creatures than cutinates whose muscles could be isolated and made to grow...

All of a sudden he felt as though a great burden had been taken from him. His mind cleared. Without his realizing, his life had been spent in the shadow of those allegedly greater than himself. They were nothing of the sort; they were merely more powerful. And the power they wielded was puny compared to Barratong's, yet the admiral was ultimately humble before the marvels of the boundless universe, which—Arranth said— now threatened them with something no Great Fleet, no member of the Jingfired, no person whatsoever could defy: a cloud of stars and interstellar gas that must be burning at temperatures unmatched by any furnace.

Compared to the cosmos, everyone was equal. Everyone was a bud of this small planet. Either everyone must work together, or in a few score generations there would be no one.

A flock of cloudcrawlers was passing. He looked up, wondering whether in their serial migration might be sought the secret of survival.

But he knew too little. Still, he had about half his life before him; there could well be tune to find out what had been discovered or invented on other continents, as well as by the People of the Sea. The most amazing chance could, as he realized, lead to practical results, and whatever chance itself might be, it had already supplied the most important information.

"The past can communicate with the future," he said aloud. "And we're the past."

"Yes, of course," said Barratong. "We have to devise gongs and banners in order to signal our successors as the Fleet does. At every port we shall leave copies of the star-maps, ancient and modern; at every port we shall leave ashore folk who, having fled drowned cities, want to start anew on land with foreign knowledge ... We dare not let blind fortune alter the world without hindrance. We too must play our part in changing it. Ulgrim, call a general meet. Today I purpose to divide the Fleet, and the planet."

The ice's burden lifted swiftly from the northern lands, and new huge rivers carved their course through what had been dry plains. Gigantic floods drowned forests and the creatures living in them; meantime, the ocean-level marked new records every spring. What had been land-bridges turned to open channels; what had been island-chains were strings of shoals.

But most important of all, the weight of frozen water had held down a necessary, long-impending shift of one continental plate against another. Part of the Great Thaw was due to absorption by the sun of a wisp of interstellar gas which for a brief while had helped to mask its radiation. The local space was temporarily clear now, and extra warmth was piercing the atmosphere because fewer dust-motes were falling from the sky to serve as nuclei around which drops of rain or hailstones might develop, and the long ice-age had inhibited production of natural nuclei due to vegetation or the smoke of wildfire.

Another reason for the Thaw, however, was to be sought in the conversion of kinetic energy to heat. Around the north pole there were geysers and volcanoes testifying to the presence of magma near the crust. Patient, they had waited out the period during which so monstrous a mass of ice lay over them that all their heat could serve to do was make a glacier slide or melt a summer valley for migrating flighters. The continental plates which powered them, however, were on a different and grander scale. No ice could long have resisted their padlong-per-year progress, and the added solar warmth did no more than hasten what was inevitable.

The ice-cap shattered in a laq of seizures, each one casting loose a craw of bergs. Lava leaking from far underground met open water and solidified and then was cast high into the air when water turned to steam. Plume followed eruption followed temblor, and at every stage more water streamed back from the arctic plateau to the ocean.

Somehow the separated Fleets survived, even though their business became, first and foremost, mere survival, and their admiral's vision of immediate salvation was eroded by the giant waves that unpredictably rushed from the north and, later, from the south as well, where there was no such enormous valley as the one which had penned in the Salty Sea to deliver its new water all at once.

Often overloaded, so they were forced to land unwilling riders on half-sunken islands in the hope at least their mountain peaks might rise above the water when the oceans calmed; often driven off course by storms such as nobody had seen in living memory; often picking their cautious way over what had been a land-mass a scant year or two ago, searching for anything which might be useful, be it edible carrion or a batch of tools and instruments which would float; often rescuing survivors from a sunken city most of whom were starved into dreamness already and having to make the harsh decision that they must be again abandoned, for their sanity was poisoned past all hope of cure; often—once the barriers between the eastern and the western oceans had been breached— confronting herds of wild briqs, savage in a way that junqs had never been and panicked by an amazing explosion of gulletfish, so that they had to reinvent on the basis of legend and guesswork the means to pith a briq, with the minor consolation that if the attempt failed there would at least be food for the folk on board, and the major drawback that the taint of their own land's ichor in the water drove the other briqs frantic with terror; often near despair and redeemed only by messages from another luckier Little Fleet, with an achievement to boast about such as the safe delivery of a group of scholars to an upland refuge...

The People of the Sea endured the horrors of the Thaw and by miracles preserved the vision Barratong bequeathed to them.

Meantime, the landsiders moved along the tracks and paths available.

Confronted by the rising water, they summoned droms and other mounts and loaded them, and struggled up steep mountainsides, collecting useful seeds and spores. Again and again the caravans were overwhelmed by hunger or sickness caught from murrained water, or trapped on a valley path when floods came rushing down. Desperate, some resorted to the use of fresh-water barqs, only to see them wilt and die when salt afflicted their tubules.

A few, however, found a way to safety, and after cautious negotiation settled on high ground near existing hamlets, being eventually made welcome because they had brought new food-plants and, above all, because they offered the chance of fertile first-time matings to communities whose numbers were diminishing.

Following the caravans, though often having to invent new routes, discontented wandering scholars trudged from town to new town seeking their lost equals, each bearing something of what had been known in a city sunk beneath the waves or lost when a hillside slumped into the sea. Occasionally they borrowed the services of the tramp junqs which, after the dispersal of the Lesser Fleets, traveled in groups of three or four and traded as best they could along inlets of the sea that formerly had been mountain passes or river-valleys. The hegemony of the People of the Sea endured, but the mixing of the landsiders resulted, almost at once, in an explosion of population, for instead of one pairing in several score producing a bud, suddenly five took, or even seven, and wise persons argued about miscegenation, and proper diet, and the influence of privation, and it seemed that most of them must be at least partly correct.

The sea-level stabilized. Those fortunate astronomers who had access to long-term brightness records for the sun admitted cautiously that it looked as though the extra heat due to infalling matter was over. Those who had preserved their presence of mind during the period of violent quakes, devising means to mark and measure the trembling of the land, noted with satisfaction that it shook only now and then, and hilltops seldom broke loose anymore. Such scientists, when they met them, the People of the Sea declared to be Jingfired, and gave them copies of the ancient star-maps. It was a mere token, for the donors scarcely understood what the maps recorded, yet they were seeds of knowledge, after their fashion. The skies cleared, and there was no longer a gritty stench when the wind blew from the north. Daringly, a few started to maintain that an outburst of volcanic dust had protected life on the planet from the worst effects of increased solar radiation ... but it was at best a guess, lacking evidence.

When the world settled back to an even keel, explorers set forth once more who employed techniques that once had been the private property of jealous cities: means to signal across vast distances, means to preserve knowledge by multiplying it in countless copies; medicines to cure common illnesses, others to master strange rare disorders; tools for tasks that most people had never dreamed of undertaking; seeds so treated they would yield edible fruit simply by being soaked in salty water when required; vegetable parchments that changed color when light shone on them, which placed at the proper distance from a lens would fix an image; juices and saps which served to bind together plant and rock, or glass and metal; vessels not of wood or hide but melted sand, not exactly glass but stiffer, wherein a fire might safely be lighted on the back of a junq without the creature suffering...

Tricks and ideas, hints and suggestions, cross-fertilized and bred faster than the population. A means was needed that would match one invention, to be exchanged, against another. After much fierce debate, it was agreed that persons schooled in the desired technique should be the unit, and the surviving Little Fleets should carry them for longer or shorter periods among the folk requesting the new knowledge. By now, however, many of the new cities had their own research groups, not to mention their own miniature Fleets and the system rapidly broke down.

It made no odds. The time was past when one city might strive for superiority over its neighbors. The impulse was for sharing, because over all of them loomed the threat which they could now read directly from the sky. Even the southmost of the settlements, shielded from all the new stars in the Smoke, accepted it. Beyond a doubt the day would dawn when the folk, in order to survive, must quit their world.

How, naturally, none yet knew...

As for the banner junq of the Great Fleet of the Eastern Sea, her last recorded trace was when they brought to Yockerbow, old then and shrunken-mantled, a bundle found among jetsam on what had been the slopes of a mountain inland from Clophical, and now was a steep beach beset by trees. His name was inscribed on it three times. The finders located him without trouble; he was famous, because he had become the lord and leader of a scientific community not quite like what he, Barratong and Arranth had envisaged, but near enough. Scholars flocked to him from every land, and new discoveries and new inventions flooded out as water had poured forth when the ice-wall broke and loosed the Salty Sea.

"Here is," he said when he had opened the bundle—with assistance, for his pressure was now weak—"the original glass tube which held the ancient star-maps. I wonder what happened to the maps themselves. Not that it matters; we've found other better copies. What map, though, could show me where to find my lost lady Arranth? What chart could guide me to my old friend Barratong? ... Oh, take this thing to the museum, will you? I have much work to do, and little time."

PART FOUR

BREAKING

THE MOLD

I

Few communities on the planet were more isolated than the settlement at Neesos, a dark-and-a-bright's swim from the mainland. Once the island had been linked to it by a narrow isthmus passable even at high tide, but the Great Thaw had drowned that along with most of its fertile land, and for scores of years it was visited solely by fisherfolk riding kyqs with their trained gorborangs perched on the saddle-branches like dull red fruit. There were still sandbanks, though, and tradition held that in the past such sand had furnished excellent glass. A certain Agnis eventually made an expedition thither and, finding the tale correct, set about producing magnifiers.

However, he did so at a time when a chillward shift in the weather had led to a revival of religion. Made hungry by the failure of staple crops, the folk were as ever victimized by those who, by starving themselves voluntarily, claimed to obtain visions of a higher reality. In truth, so Agnis charged, what they craved was power over others, and they hoped to gain it by preventing the public from directly consulting the Jingtexts, wherein might be sought solutions to all worldly woes ... not, naturally, that every humble person might aspire to read the ancient teachings without guidance, for they were couched in archaic symbols, a far cry from the crisp and simple script used for modern messages, and the speech itself had changed almost beyond recognition.

This did not content the relidges, eager as they were to draw down everybody to that mental level where reason was indistinguishable from dreamness. Sight was the first mode of perception to be diminished by famine, as weather-sense was the last, but it was in vain for Agnis to argue that by providing artificial aid he was encouraging the spiritual advancement of the folk. The relidges countered by saying it made them more vulnerable to the rationalist writings now being distributed in countless copies thanks to the invention, by some foreigner beyond the horizon, of a vegetable which could be made to ooze blackish stains on a dry absorbent leaf in exact imitation of any mark inscribed on its rind.

Images had long been fixable, at least in one color; soon, it was claimed, means would be found to reproduce them as well.

Despairing, Agnis gathered his family and a few supporters and made for Neesos with the town's entire stock of burnable wood. The cool phase of the climatic shift, far from enough to reinitiate the Northern Freeze, did not prevent the sky being bright over this region for almost half the year, and when the sun was up its rays could be focused. Using his pilfered fuel, Agnis cast a giant mirror and with it melted colossal quantities of sand. This served to fabricate spyglasses of outstanding quality, such as lured not only fisherfolk but even the all-powerful People of the Sea. Shortly his village was better off than the town its inhabitants had quit, since the latter had little left worth trading for.

Sometimes the settlers found relics of the far past in the shallow waters around Neesos, and they too served for trading purposes, mysterious though their nature might be to the modern mind. In consequence, it was into a community more prosperous than its isolation might have suggested that Tenthag—half a score of generations in direct succession from Agnis himself—was budded in the year called Two-red-stars-turn-blue.

But the community was so small that the People of the Sea were rarely able to trade what they most wanted and needed at Neesos: stock with which to cross-breed themselves. They had sampled every genetic line on the island, and every line, in turn, was already spiked with some of the travelers' ichor.

Long-lived, reasonably content, the folk of Neesos were resigned to budding being rare. It was not until three quarter-score of years had slipped away that they began to notice:

There has been no new bud since Tenthag.

As soon as they realized he was "special" the folk of Neesos started to pamper the boy, which he found no fun at all, for it meant he was forever being prohibited from doing the things the other young'uns enjoyed. The old'uns said "protected," but it amounted to the same boring thing.

Yet his slightly older companions were contemptuous of his youth, and very shortly there was only one left for him to play with. The rest had gone on to the pretence of being grown-up, although their matings led to no offspring. Tenthag wished achingly that they would, to release him from his confinement in a web of concern.

Still, his father Ninthag was a perennial optimist and, despite the pleas of Sixthon who had budded Tenthag for him and never childed with anybody else, he was happy to turn a blind eye when his son did what in olden times all young'uns were accustomed to—go swimming out of storm-season on the northern coast—along with Fifthorch, who was next-to-youngest.

Here there were beaches sown with rocks defining the trace of what had been Prefs, the port serving crag-beset Thenai in the days before the water-level rose a score of padlongs. Great ocean-going briqs and junqs had unloaded here, revealing marvels brought from half the world away, and sometimes odd bits and pieces that had proved unsalable had been tossed overside before the fleets returned to sea. Young'uns sought for them, trapping as much air as possible beneath their mantles before they dived, in the hope of retrieving artifacts intact. But that had been in the old days. Now only scraps were to be found, at least at any level they could reach.

Nonetheless Fifthorch spent as much time as he was spared from his apprenticeship at the general trade of glassworking, plunging and basking around the northern shore, and perforce Tenthag tagged along. He did not really like Fifthorch, but there was no alternative; he so hated being fussed over and petted by the old'uns.

Eventually, they all assumed, he would fall into the standard pattern of the island's folk, and were its population to die out, someone else would take it over. That was the way it had been since time immemorial, and even though a few stars might turn color, life down here was not expected to alter very much. The age of changes seemed to be long past, bar the occasional shift of weather.

It did sometimes puzzle Tenthag why, if nothing was to change worth mentioning, there should be so many relics of a different past lying just off shore. But when he tried to talk about this to the old'uns they were always busy with something else, and if he voiced his private anxieties to Fifthorch, the latter mocked him, quoting what he had been told by his own father, who despised the Jingtexts.

"The form of now is permanent," he would insist. "If there were changes in the past, it must have been because what passed for people then were only animals. We were set here by the Evolver to use and exploit the lower orders. Now we know how to do it—we have gorborangs to catch fish for us, we have kyqs to ride on when we put to sea, we eat enough to let us tell reality from dreamness, we live a proper life that must not be disturbed! And nothing can, and nothing will, disturb it!"

Thereat, becoming bored, he would propose a diving expedition, and— not wanting to seem ungracious, nor to become bored himself—Tenthag would once more risk the effect of salty water on his tegument.

He relished the experience of plunging through the ocean shallows, as his ancestors must once have plunged through air from branch to branch of forests now lost beneath the waves, but he could never quite rid himself of awareness of what nightly he saw marked out on the sky. Since he quit infancy and was able to erect himself and raise his eye to the zenith, he had been fascinated by those brilliant spots and streaks ... and started to wonder why his elders never paid them any attention except when there were unusual displays, and seemed almost to welcome the dull season—regardless of its storms—when clouds closed over land and sea alike. Did not the Jingtexts refer to changes which...?

But "change" and "Jingtext" were incompatible, they said, one necessarily contradicting the other. If a scripture spoke of change, it must be taken metaphorically, as parable. The year of his birth, when two stars turned to blue, was dated in the manner of a nickname.

And so it went, with Tenthag defeated at all turns, until the year whenafter the world could never be the same.

II

It wasn't kyqs that year which swam into the bay as soon as the spring hail died away, but junqs and briqs far grander than ever had been seen before at Neesos. Moreover, they arrived without the slightest warning.

Led by Ninthag and his deputy, Thirdusk, the folk assembled on the shore in mingled wonder and apprehension. Even the People of the Sea did not boast such magnificent steeds, so finely caparisoned with secondary life-forms. Who could these strangers be?

Very shortly the explanation spread, and generated universal amazement. Those who had come hither were not any sort of common trader, though prepared to pay for what they took; they hailed from a city far to the south, called Bowock, and they went by a name whose roots were drawn from Ancient Forbish, "archeologists"—which some of the more learned of the folk patronizingly rendered into today's speech for the commonalty, making it "pastudiers."

What they wanted, they declared, was to explore the underwater ruins, and they would offer either food and tools for the privilege, or new kinds of seed and animal-stock, or something abstract known as "credits" which allegedly would give the folk of Neesos privileges in return if ever they were to visit Bowock. Since nobody from here in living memory had voyaged further than the horizon, the latter were turned down at once, but the rest appealed, and a bargain was struck with which the majority of the folk were in agreement. What little wariness remained soon melted when the newcomers exclaimed over the fineness of the local glass and ordered magnifiers, microscopes and new lenses for a strange device used to find relative positions, hence distances otherwise impossible to measure. These they exchanged for the right to deepwater fish caught from their junqs and briqs.

Almost the sole person who continued to grumble about this intrusion was Fifthorch, because the strangers had occupied his favorite area for swimming.

Not wanting to lose his only friend, or what passed for one, Tenthag dutifully agreed with him, even though his pith wasn't in it. He was fascinated by the newcomers, above all because, for people concerned with the past, they had so many new gadgets and inventions at their disposal. They had set up a mainland base, where they were necessarily treating with the folk of the town the Neesans' ancestors had fled from— though time had healed most of the old wounds—and made some sort of connection with it to carry news faster than the swiftest briq could swim. A cable like a single immensely long nerve-strand had been laid along the sea-bed between the two places, and covered over with piles of rock carefully set in place by divers wearing things called air-feeders: ugly, bulging, parasitical organisms bred from a southern species unknown, and unhappy, in these cool northern seas, which somehow kept a person alive underwater. Also they had means to lift even extremely heavy objects, using some substance or creature that contracted with vast force.

Such matters, though, the Bowockers were secretive about. To those who asked for information concerning them they named an impossibly high price. Anyway, there was scant need for such devices here.

Otherwise they were not unfriendly, and came ashore by dark to chat, share food and otherwise socialize; a few of them knew songs and tales, or played instruments, and became tolerably popular. Inevitably, too, there were pairings, but none resulted in a bud, although Tenthag desperately hoped they might. He was tired of being the permanently youngest.

The same problem apparently beset Bowock, though. Now and then the divers, ashore to recover from the toll exacted by their work, would grow confidential after sampling the powerful local araq, and admit that at home there were too few buds to keep up the population, despite contacts with other cities and the People of the Sea. Some went so far as to wonder aloud what they were doing all this for, if in a few score-of-score years there might be no one left to enjoy the knowledge. But they kept on regardless.

What precisely the knowledge was that they hoped to garner from the broken fragments they brought up, the folk of Neesos could not imagine. Little organic material resisted the erosion of salt water; tides and currents had scattered what did endure, like blades, lenses and the burnt-clay formers used to compel houseplants to grow into the desired shape. Within a couple of months most people stopped wondering, and treated the strangers as a familiar feature of the locality.

Tenthag was almost the only exception.

Nonetheless, the day came when some most exciting discovery was made—to judge by the noisy celebrations the pastudiers spent a whole dark in—and shortly afterwards a single rider arrived mounted on a sea-beast such as nobody had ever sighted in these latitudes before. She was unbelievably swift in the water, casting up a snout-wave that broke in rainbow spray, and nearly as large as the smaller junqs, but with a tiny saddle and virtually no secondary plants. She had an appetite of her own, though, and a huge one. Cast loose to browse in the next bay to where the pastudiers were working, she gulped and chomped and gobbled and gulped again the whole dark long. When they were asked about her, the strangers said she was an unpithed porp, specially bred for high-speed travel.

The idea of a porp, even a tame one, in the local waters was not calculated to appeal to the folk of Neesos. Schools of such creatures were reputed to strip vast areas clear of weed and drive away the sorts of fish the folk depended on. However, the Bowockers promised that she would leave again at dawn, carrying important news. What kind of news, they as usual declined to say.

By now there was a feeling among the folk that they should be entitled to a share in the pastudiers' discoveries, and Fifthorch's parents were among the loudest with complaints, although they personally did nothing to cultivate the visitors' acquaintance and laid all the responsibility on Ninthag and Thirdusk. The night when the porp was feeding, Tenthag grew sufficiently irritated by Fifthorch's automatic repetition of his father's arguments to counter them with some of Ninthag's. The result was a quarrel, and the older boy went storming off.

Alone in the dark, under the bright-sown canopy which was as ever shedding sparkling starlets, Tenthag turned despondently towards the beach. He was so lost in a mix of imagination, memory and dream that he was startled when a female voice addressed him.

"Hello! Come to admire my porp? I understand you people don't tame any sea-creatures but kyqs, right?"

Taken aback, he glanced around and spotted the person who had spoken: a she'un only some half-score years his senior, relaxing in a pit in the sand.

This was the rider who had made so spectacular an entry into the bay? But by comparison with the monstrous beast she rode, she was puny! Even erect, she would be a padlong below him, and he was not fully grown.

"We—uh—we don't know much about them," he forced out as soon as enough pressure returned to his mantle. "Certainly taming porps is a new idea to us."

"Oh, where I come from there's never any shortage of new ideas! Our only problem is finding time to put them all into practice. Are you going anywhere, or would you like to talk awhile? I'm Nemora of the Guild of Couriers, in case you hadn't guessed. And you are—?"

"Tenthag," he answered, feeling his courage grow. "And ... Well, yes, I'd love to talk to you!"

"Then make yourself comfortable," she invited. "You've eaten, drunk, and so on?"

"Thank you, yes. We feed well here, and all the better"—he thought of the compliment barely in time—"because of the Bowockers who bring us deepwater fish."

"Yes, normally you only work the shallows, I believe. Well, here's something from my homeland which may tempt you even if you're not hungry. Try some yelg; it's standard courier ration, but I have more than enough for this trip because my lovely Scudder is so quick through the water."

What she offered was unfamiliar but delicious, and within moments he felt all temptation to slip into dreamness leave him. He was in full possession of himself.

"I hope I'm not keeping you from your friends," he said.

"Friends? Oh, you mean the archeologists! No, I don't know them. Anyhow, they're too busy to be bothered with a mere courier. They hadn't finished preparing their reports and packaging what they've found, because they figured I wouldn't be here until tomorrow. But, like I said, Scudder is the record-breaking type ... Oh, there goes a beauty!"

A wide and brilliant streak had crossed the sky, to vanish behind low cloud on the eastern horizon. For a moment it even outshone the Major Cluster, let alone the Arc of Heaven.

"There isn't much to do when you're a courier," she said musingly, "except to watch the weather and the sky. Yet I wouldn't trade my job for anyone's."

"I don't believe I ever heard of the Guild of Couriers before," Tenthag admitted.

"Really?" She turned to him in surprise. "I thought we'd pretty well covered the globe by now—but come to think of it they did warn me I was going to a very isolated area. Well, essentially what we do is keep people in touch with one another over distances that nervograps can't span, and transport bulky items which briq and junq trade would delay or damage. That's why I'm here, of course: they found what they were looking for, and the relics are extremely fragile. But you must know about that."

"I'm afraid they don't talk to us about what they're doing," Tenthag muttered. "Not even to the old'uns, let alone someone of my age."

"Oh, that's absurd! I'll have to mention it when I get home. We couriers have strict instructions from the Order of the Jingfired to maximize trade in information. The Guild was originally founded to spread news of the musculator ... but I sense you aren't following my meaning."

By now Tenthag was emitting such a pheromone-load of incomprehension he was embarrassed. Nemora, in contrast, exuded perfect self-confidence and, impressed by her tact, he was shortly able to respond.

"The word is new to me," he confessed. "Same as—what was it you said?—nervograp?"

"Hmm! No wonder you still only hunt the shallows! But you must have seen the musculators working here, and you could trade something for a brood-stock. They say you make good glass, and—Oh. Never tell me these 'friends' of mine have bought your entire supply for much less useful goods!"

"I believe," Tenthag answered, quoting what he had heard from Fifthorch, "they've commissioned a whole summer's output."

"For supposedly dedicated students of the past, they're far too mercenary, then. I'll report that, definitely. Well, a musculator is what you get when you breed a particular type of shore-living creature for nothing but strength—not even mobility, nothing else except the power to contract when one end is in fresh water and the other in salt. You feed it a few scraps, you can breed from it in turn, and you use it for—oh—pumping water where it's needed, lifting heavy weights, hauling a load across a mountain gorge where mounts can't go, and things like that. And a nervograp ... But there's one in operation between here and the mainland, isn't there?"

"A way of signaling?"

"Ah, you know about that, at least. That's much newer than musculators, of course—in fact, so new that we're still stringing them overland between cities, and I think this is the first-ever underwater connection. I hope it's being done in time, that's all. We've got to link up everybody on the planet if we're ever to get away."

There followed a long baffled silence. Reacting to it, Nemora said eventually, "I'm sorry about that. I was just so stunned to realize you had no idea what I'm referring to. Aren't the Jingtexts available on Neesos?"

"Not many people can read them," Tenthag muttered. "I've never been allowed even to study the language of them."

"But this is awful!" She erupted out of her sitting-pit in a single graceful surge, and Tenthag had his first chance to see her entire. He was embarrassed all over again. She was perfectly lovely, and there was no way he could hide the exudate that signaled his reaction. Luckily she took it as a compliment.

"Hold that for a while, young'un!" she commanded. "There are some things more important than pairing, you know! You really haven't been told that our sun and all its planets are being drawn into the Major Cluster, and if we don't escape we shall wind up fueling a celestial fire? My goodness, how old are you?"

He had to answer frankly, though he could have wished to pretend he was older. Lying was pointless with anybody who had a weather-sense as acute as Nemora's ... and would not someone who piloted a porp single-clawed across great oceans have been selected for precisely that talent?

"I was born in the year called Two-red-stars-turn-blue."

"Then you really ought to be better informed! Why did they turn blue?"

"People here don't pay much attention to the sky," he said defensively.

"That's obvious! Well, the answer is this." Padding up and down, so that her mantle rippled in curves it almost hurt him to watch, she launched into the sort of lecture he had always dreamed of being given by someone older and wiser than himself. "The fixed lights in the sky are suns like ours, but far away. We have records showing that some of them, the nearest, are moving apart; this proves that we're approaching them. I don't mean the ones that move visibly. They're planets like ours, revolving around our sun, and the ones that spill out of the sky are just odd lumps of nothing much which heat up when they fall into our air. But there are too many of them for comfort. We think we're drawing closer to a volume of space where there are so many of these lumps that some must be very big indeed, big as the nubs of comets, and if one of them falls on a city, or even in mid-ocean—! And eventually we think our whole world may be drawn into a sun and go up in another star-turned-blue. The more fuel you put on a fire, the hotter it gets, right? And we don't want to be burned!"

Once more there was a period of silence, but this time it was for reflection. Tenthag felt as though he had been afflicted with acute mental indigestion, but what Nemora had said made excellent sense. Besides, how could someone as ignorant as himself challenge her?

He wanted to ask another million questions, but suddenly one became more urgent than any other. He said faintly, recalling what he had heard about the Bowocker divers, "Just now you told me there were some things more important than pairing. But suppose we don't breed, and there aren't enough people left when we find out how to—what did you say?—escape? In any case, I don't see how we could! First we'd have to learn to fly like cloudcrawlers, and then..."

Speech failed him; he sat dumbstruck.

With a deep chuckle she dropped beside him, so close their mantles touched.

"There are people working on means to fly better than cloudcrawlers," she murmured. "One of these days I hope to carry the news of somebody's success in that endeavor. But you're perfectly correct. There must be people to enjoy the benefit of what we're doing now. Would you like to pair with me? I guess it may be your first time, and they do say a first tune can be fruitful."

When she departed after dawn, she left behind a transformed Tenthag, who knew beyond a doubt what he wanted to make of his life. To the dark with glassworking! He was determined to be like Nemora: a courier.

III

Later Tenthag concluded ruefully that if he'd realized how much he had to learn, he would probably have changed his mind. Life on Neesos had not prepared him for the complexity of the modern world, and particularly not for Bowock with its eleven score-of-scores of people, its houses every one of which was different (for the city itself served as a biological laboratory and experimental farm), and its ferment of novelty and invention.

Despite its multiplying marvels, though, which rendered public notice-slabs essential—announcing everything from goods for trade through new discoveries seeking application to appeals for volunteer assistance— there was a taint in Bowock's air, an exudate of anxiety verging on alarm. It was known that scores-of-scores-of-scores of years remained before the ultimate crisis, and few doubted their species' ability to find a means of escape, were they granted sufficient time.

In principle, they should be. Disease was almost unknown here and in other wealthy lands; crop-blights and murrains were held in check; everyone had food adequate to ensure rational thinking; maggors and wivvils and slugs were controlled by their own natural parasites—oh, the achievements of the Bowockers were astonishing!

But Nemora had not taken his bud, or anyone's. His first frightened question, so long ago, so far away, on the dark beach of Neesos, was one which everybody now was asking. Indeed, it had been Nemora's commendation of his instant insight which had secured him his appointment as a courier-to-be.

Hence his excitement at the challenging future he could look forward to was tempered by the sad gray shadow of a nearer doom. He tried to lose himself in training and caring for the porp assigned to him, modestly named Flapper, but even as he carried out his first solo missions—which should have been the high point of his life so far—he was constantly worrying about the folk he had left behind on Neesos, condemned to grow old and die without a single youngling to follow them.

He felt a little like a traitor.

"It is Neesos that you hail from, isn't it?" said the harsh familiar voice of Dippid, doyen of the couriers.

Tenthag glanced round. He was in the pleasant, cool, green-lit arbor of the porp pens, formed by a maze of root-stalks where the city's trees spanned the estuary of a little river. Porps became docile automatically in fresh water, a fact first observed at Bowock when one of them was driven hither from the open sea for an entirely different purpose, and between voyages they had to be carefully retained.

Alert at mention of his home, he dared to hope for a moment that he was to be sent back there. Giving Flapper a final caress, he swarmed up the nearest root-stalk to confront Dippid ... who promptly dashed the notion.

"The stuff that Nemora brought back from the trip when she met you: it seems to have borne fruit. You know about the work that Scholar Gveest is doing?"

Tenthag scoured his pith, and memory answered. "Oh! Not much, I'm afraid——just that he's making some highly promising studies on a lonely island. It's an example of information, trade in which has not been maximized," he added, daring.

But it was a stock joke, and Dippid acknowledged it with a gruff chuckle.

"People's hopes must not be inflated prematurely," was his sententious answer. "But ... Well, we've had a message from him. He believes he's on the verge of a breakthrough. What he needs, though, is someone from Neesos to calibrate his tests against."

"Why? What sort of tests?"

"You know what it was that they recovered from the sea-bed at Prefs?"

"I'm not sure I do. I—ah—always got the impression I was supposed not to inquire. Even Nemora was elusive when I asked about it. So..."

Dippid squeezed a sigh. "Yes, you judged correctly. I sometimes wish I didn't know what Gveest is working on, because if he fails, who can succeed? But enough of that." He drew himself up to a formal stance.

"Here's your commission from the Council of the Jingfired, boy. You're to make with all speed for the island Ognorit, and put yourself at Gveest's entire disposal."

"Did you say Ognorit?"

"I did indeed. What of it?"

"But that's south of the equator, isn't it—part of the Lugomannic Archipelago?"

"You've learned your geography well!"—with irony. "But I've never been into the southern hemisphere before!" "There's a first time for everything," Dippid snapped, and clacked his mandibles impatiently. "And if what Gveest is doing turns out wrong, it would be a great advantage to have the equatorial gales between us and Ognorit! Don't ask what I mean by that. Just put to sea. You'll find out soon enough."

It was by far the longest voyage Tenthag had undertaken, and he often wished that Flapper were as swift as Scudder. But each bright-time she pursued her steady way, and each dark she fed and gathered strength anew. She might not be particularly quick, but she was trustworthy, and never turned aside, not even when all her instincts tempted her to run off with a school of wild'uns, or follow a sharq's trail of murder across a shoal of errinq, or flee from the suspected presence of a feroq, the traditional enemy of porps. Little by little he was able to relax.

Cronthid went by, and Hegu, and Southmost Cape, and another day saw them entering the Worldround Ocean, that huge sea where currents flowed around the planet uninterrupted by continental masses. Once it had been different; the Great Thaw had altered everything. Tenthag watched the patterns in the sky change as they drove south, and felt in his inmost tubules, for the first time, that he did truly live on a vast globe adrift in space.

He had to apply all his navigational skills to the correction of Flapper's course; her impulse was to follow odor-patterns and temperature-gradients. He was obliged to ply his goad more often than he liked, but she responded, though she grew a trifle sullen.

Stars he had never seen were their guide now. But he had been well taught, and felt relieved to find his instructors' maps reflected in reality.

Islands loomed and faded, but he ignored them save to check his calculations. Then came a major problem: rafts of rotting weed, each alive with its own population of wild creatures, and uttering pestilential swarms of mustiqs. Someone had forgotten to advise him that it was the southern breeding-season ... though, of course, he should in principle have known. Itching, swollen, worried by the way they clustered on Flapper's mantle, he was overjoyed when he raised a squadron of free junqs belonging to the People of the Sea. They were much less pleased than he by the encounter, for they regarded the Bowocker courier service as having cheated them of their ancestral rights; for scores-of-scores of years it had been their sole prerogative to trade in information, ever since the days of the Greatest Fleet created by Admiral Barratong.

Tenthag, though, was empowered to issue certain credits redeemable at Bowock and its allied cities, and some of them ensured the chance of pairing. Like every other branch of the folk, the People of the Sea were growing frightened at the fewness of their buddings, so he was able to convince them to part with a couple of spuderlets. Within half a day Flapper was protected from prow to tail by a dense and sticky web, and so was he; it made life easier to watch the baffled mustiqs fidget and struggle in their death-throes. Also they were a useful adjunct to his stock of yelg, and rather tasty.

Then came a storm.

It blew and poured and pelted down for a dark and a bright and a dark, and when it cleared Tenthag was more scared than ever he had been in his young life. He had clung to Flapper—who seemed almost to exult in the violence of the waves—and his stores were safe under her saddle and the spuderlets had made themselves a shelter out of their own web-stuff, and all seemed properly in order but for one crucial point:

Where had the tempest driven them?

There were islands low on the horizon when dawn broke. It was self-insulting for a courier to ask the way, but there seemed to be no alternative. He goaded Flapper towards a cluster of small barqs putting to sea under the wan morning sky, their riders trailing lines and nets for fish.

When he hailed them, they said, "Ognorit? Why, it's half a day's swim due south!"

Half a day? The storm had done him favors, then! Even the fabled Scudder—growing old now—could have brought Nemora to this spot no quicker!

He was already preening when his porp rushed into a narrow bay between two rocky headlands, and an old, coarse-mantled figure padded into the shallows to shout at him.

"You'll be the courier from Neesos that I asked for! It's amazing that you're here so soon—though I suppose you actually started from Bowock, didn't you? Welcome, anyway! Come ashore! I'm Scholar Gveest, in case you need a name to tell me apart from all the animals!"

IV

The meaning of that cryptic statement was brought home to Tenthag as soon as he had set Flapper to browse—a duty he discharged meticulously despite Gveest's obvious impatience.

Then, heading inland in the scholar's pad-marks, he found himself assailed by hordes of wild creatures. Some leapt; some slithered; some sidled; some moved with sucking sounds as they adhered and freed themselves. Gveest was not afraid of them, and therefore Tenthag was not. But what could they possibly be?

Abruptly he caught on. He recognized them, or at any rate the majority; it was just that he had never seen more than one or two of them before in the same place. Whoever heard of six vulps in a group, or nine snaqs, or a good half-score of jenneqs, or such an uncountable gang of glepperts?

His tubules throbbed with astonishment. Whatever Gveest was doing, it had resulted in a most amazing change of these species' usual habits!

And the house he was taken to, on a crest dominating the whole of the island, reflected the same luxuriance. There were trees and food-plants massed together in quantities that would not have shamed Bowock itself, or any rich city in the north. Suddenly reacting to hunger despite his intake of yelg and mustiqs, Tenthag could not help signaling the fact, and Gveest invited him to eat his fill.

"Be careful, though," he warned. "Some of the funqi in particular may be rotten."

Edible food, left to rot? It was incredible! Was Gveest here alone? No, that couldn't be the explanation; here came two, three, five other people whose names he barely registered as he crammed his maw.

Belatedly he realized that his journey had made him sufficiently undernourished to exhibit bad manners, and he quit gobbling in embarrassment, but Gveest and his companions reacted with courteous tolerance.

"You got here with such speed," the scholar said, "we can't begrudge recuperation time. My colleague Dvish, the archaeologist, informed me that the courier who brought away his precious discoveries from Neesos also surprised his party. The efficiency of the Guild remains admirable."

Though as soon as they learn to string nervograps from continent to continent, and convey images along them...

Tenthag clawed back the thought. It was bitter for him to admit that, in his amazement at the greater world, he had committed his life to what might shortly become an obsolescent relic of the past. But pretense was useless when dealing with a weather-sense as keen as Gveest's; the scholar must be a match for Nemora, for he was going on, "And despite your worries, there will be need for courier-service for a long, long while. Regardless of the principle of maximizing trade in knowledge, some things are too fraught with implications to be turned loose ... yet. That's why you're here."

Confused, Tenthag said, "I expected to bear away news of some great discovery you've made!"

The party surrounding Gveest exchanged glances. At length one of them—a woman, whose name he faintly recalled as Pletrow—said, "It's not what you're to take away that matters right now. It's what you brought!"

"But I brought nothing but myself!"

"Exactly."

After a pause for reflection, Tenthag still found no sense in the remark. Moreover she, or someone, was exuding a hint of patronizingness, which in his still-fatigued condition was intolerable. He rose to full height.

"I am obliged to remind you," he forced out, "that a courier is not obliged to wait around on anyone's convenience. Unless you have data in urgent need of transmission—"

"We sent for you not because you're a courier but because you're from Neesos!" Ill-tempered, Pletrow strove to overtop him, and nearly made it. The air suddenly reeked of combat-stink.

"Calm!" Gveest roared. "Calm, and let me finish!"

Always there was this sense of being on the verge of calamity, and for no sound reason ... In past times, so it was taught, only male-and-male came into conflict; Pletrow's exudations, though, were as fierce as any Tenthag had encountered. But a timely breeze bore the stench away.

"We had expected," Gveest said in an apologetic tone, "that any courier sent here would be fully briefed about our work."

"Even the chief courier told me he wished he didn't know about it," Tenthag retorted. "So I didn't inquire!"

"Then you'd better make yourself comfortable, for when I explain you'll have a shock. The rest of you, too," Gveest added, and his companions swarmed to nearby branches, leaving a place of honor to Tenthag at the center.

Lapsing into what, by the way he fitted it, must be his own favorite crotch, the scholar looked musingly at the patches of sky showing between the tangled upper stems of his house. The fisherfolk's estimate of half a day's swim had been based on the southern meaning of "day"— one dark plus one bright—and the sun had set about the time Tenthag came ashore. Clouds were gathering, portending another storm, but as yet many stars were to be seen, and some were falling.

"Are you surprised to find so many animals here?"

"Ah ... At first I was. I wondered how this island could support so many. But now I've seen how much food you have—some of it even going bad—I imagine it's all the result of your research, on plants as well as animals."

"You're quite correct. It seemed essential to improve the food-supply before—" Gveest checked suddenly. "Ah, I should have asked you first: do you know what Dvish recovered from the underwater site at Prefs?"

"The people who dived there wanted too much for the information," Tenthag answered sourly. "And since I joined the Guild the Order of the Jingfired have decreed it a restricted question."

"Hmm! Well, I suppose they have their reasons, but I for one don't accept them, so I'll tell you. During the years prior to the Great Thaw, the people there—presumably having noticed that ice could preserve food for a long time against rotting—became sufficiently starved to imagine that living creatures, including the folk, could also be preserved and, at some future time, perhaps resurrected. Nonsense, of course! But they were so deranged, even after the Thaw began, they went right on trying to find ways of insuring a dead body against decomposition. And one of their late techniques, if it didn't work for a whole body, did work for individual cells. We found a mated pair, sealed so tightly against air and water that we were able to extract—You know what I mean by cells?"

"Why, of course! The little creatures that circulate in our ichor and can be seen under a microscope!"

"Ah, yes—your people make good magnifiers, don't they? Good, that saves another lengthy exposition ... Excuse me; it's been so long since I talked to anyone not already familiar with our work." Gveest drew himself inward, not upward, into a mode of extreme concentration. Frowning from edge to edge of his mantle, he continued, "But that's only one kind of cell. Our entire tissue is composed of them. And even they are composed of still smaller organisms. And, like everything else, they're subject to change."

This was so opposed to what he had learned as a child, Tenthag found himself holding his pulsation with the effort of paying attention.

"And the same is true of all the creatures on the planet, that we've so far studied. Above all, there was one enormous change, which judging by the fossil record—You know what I mean by fossils?"

There had been few at Neesos, but other couriers had carried examples around the globe, including, now Tenthag thought of it, some from this very island. He nodded.

"Good. As I was about to say: there was one gigantic change, apparently around the time of the outburst of the New Star, which affected all creatures everywhere. We came to Ognorit because it's one of the few peaks of the pre-Thaw continents where many relics of lost animals can be dug up. Better still, some local species endured and adapted. They offer proof that we're descended from primitive life-forms. Marooned on islands like this one, creatures recognizable in basic form on the continents are changing almost as we watch, in order to fill niches in the ecology which were vacated by other species killed off by the Freeze or the Thaw. We mainly haven't changed because, thanks to the People of the Sea, we were protected against the worst effect of those disasters. But even though we don't know how some event far off in the void of space can affect our very bodies, something evidently did. There was a brief period when we were multiplying rapidly, owing to the miscegenation which the Thaw engendered. It served to disguise a terrible underlying truth, but now there's no more hope of fooling ourselves. We are afraid— aren't we?—that we may die out."

Hearing it put in such blunt terms, Tenthag could not prevent himself from shrinking.

Rising, starting to pad back and forth like Nemora on that distant beach at Neesos, the scholar continued with a wry twist of his mantle.

"Yet for a species that has the power to reason about a doom written in the stars, it's an unjust fate! Have we not thought—not dreamed, but reasoned—about surviving even if our planet goes to fuel a star? Have we not contemplated that destiny since the legendary days of Jing and Rainbow? That's what drove me here to work on my theory ... which, I hope against hope, has proved to be valid."

Calm again, Pletrow said, "You're right, if anybody can be absolutely right in this chaotic universe."

"Thank you for that reassurance. But we must clarify our reason for demanding samples of a Neesan mantle."

"Mine?" Tenthag could achieve no more than a squeak.

"Yes, Master Courier: yours. It is imperative." Gveest turned half-aside, as if ashamed, although his exudates continued to signal arrogant self-confidence. "You are of the only stock on the planet isolated enough to let us make the comparisons necessary if we are to advance our success with lower animals and improve the reproduction of our own kind. We must know exactly what sort of changes have taken place, because we intend to reverse them."

Tenthag sat stunned. It was as grandiose a notion as he had ever dreamed of, and he was hearing it stated in real time, in real life, as cold potential fact.

He husked at last, "I'm not sure, even yet, what it is you want of me!"

"About as much of your mantle as Pletrow could scrape off with one claw ... Ah, but a final and important question: do you recognize this lady as one of your own species?"

Gveest came to a halt directly confronting Tenthag, and waited.

"Of—of course!"

"But I'm not," said Pletrow, and descended from her branch to stand by Gveest.

"But I could pair with you!" Tenthag exclaimed, beginning to be more afraid than even at the height of the storm on his way hither.

"That's so. But we wouldn't bud."

"How can you be sure? I know mostly it doesn't happen nowadays, and I myself was the last on Neesos, but—Oh, no!"

Fragments of what he had learned by chance during his time as a novice courier came together in memory and made terrible sense. He waited, passive, for the truth to be spelled out.

Gveest announced it in a rasping voice.

"Here, and elsewhere around the planet, we have tasted the fossil record. We hunted above all for our common ancestors. We haven't found them. What we have found, and the discovery at Neesos was its final proof, is two separate species which evolved in total symbiosis. You and I, Tenthag, can't reproduce without the mediation of that species which evolved with us and gradually took over the role of bearing our young. We must have been in the closest competition, craws of years ago, equally matched rivals for supremacy. One species, though, opted for acceptance of the other's buds, while mimicking to perfection its behavior—as far as speech, as writing, as intelligence! And we aren't alone in this! Why, for example, does one only tame female barqs—briqs—junqs—porps? Those are the malleable, the pliant ones, who adopted the same course as what we call our females, at about the same time in the far past as we were establishing our rule over dry land! We are the highest orders of what some folk are pleased to call 'creation'—though if indeed some divine force called us into existence, I personally would have been glad to give that personage a bit of good advice!"

He was pulsing so hard, Pletrow turned to him in alarm and laid a friendly claw on his back. In a moment he recovered, and spoke normally.

"Well, anyway!" he resumed. "We hypothesize that in the early stages it was approximately an even chance whether implantation of a bud resulted in offspring for the 'male' version, the implanter, or the recipient, whose hormones were provoked into reproductive mode by impregnation and sometimes outdid the invader, thereby budding a female. We know parasitic organisms, especially among jenneqs, which still depend on the host's hormones to activate their buds; sometimes they lie dormant for a score or more of years!

"But at just about the tune the New Star is said to have exploded, wherever and whatever it may have been—I'm no astronomer, but they say it was somewhere around the Major Cluster—something provoked the 'female' species into yet another round of mimicry. It must have been a valid defense technique at some point in the far past, but extending it has cost them and us our reproductive capability. Tenthag, when Pletrow confronted you, were you not shocked at how male her exudates appeared?"

"I was," said Pletrow before Tenthag could answer. "It's the survival of us all that is at stake. New friend!"—she spoke as she advanced on Tenthag, mantle open in the most intimate of all postures—"do help Gveest! Don't turn him down! I cringe before you and invoke your aid!"

Suiting her actions to her speech, she shrank to two-fifths of her normal height, and bent to touch the courier's pads.

"It is other than my familiar duty," Tenthag achieved at last. "But I was instructed to put myself at Gveest's disposal absolutely, so—"

Pletrow uttered a cry of joy, and as she rose scratched the underside of Tenthag's mantle, which by reflex he had opened as to greet her. Before he could even react to the trivial pain, the threatened storm broke over Ognorit, and the house's retracted leaves unfolded, shutting out the sky, so as to channel the precious water to the ditch around its roots.

Instantly there was a clamor from the animals outside, for they knew this gift from heaven would result in an explosion of funqi and other food.

"Long ago," said Gveest, during the brief dark before the house's luminants responded, "there must have been a clash between symbiosis and extinction. Our ancestors preferred symbiosis, so we have to accept it. But the natural system was so delicate, so fragile, that even the explosion of a distant star could ruin it. It's up to us to create a better, tougher one. And this gift from you, Tenthag"—he held aloft the scrap of mantle-skin which Pletrow had passed to him—"may provide us with the information that we need. If it does," he concluded dryly, "they'll remember you one day as a savior like Jing!"

"And if it does," Pletrow promised as the luminants grew brighter, "I'll make amends to you for that small theft of your own substance. I want—oh, how I want!—to bear a bud!"

She clutched him to her for a moment, and then the company dispersed, leaving Tenthag alone with his mind in tumult.

V

In its way, Ognorit proved to be a greater wonderland for Tenthag even than Bowock on the day of his arrival there. Never had he seen a place where everything was so single-mindedly dedicated to one common goal. The island was a maze of experimental farms, pens for livestock, streams and rivers dammed to isolate breeding populations of fresh-water fish, salt-water pools above tide-level kept full by musculator pumps ... and everywhere there were exposed fossils, revealed when thin sheets of compacted clay or slate had been painstakingly separated. He was able to taste for himself how ancestral forms differed from modern ones, though the faint organic traces were evaporating on exposure to the air.

"If only we left behind something more durable than claws and mandibles!" said Pletrow wryly; to compensate for her irascibility she had undertaken to act as his guide, and was proving an agreeable companion. Gveest, once possessed of the tissue-sample he had asked for, had vanished into his laboratory, barely emerging for a bite of food at darkfall. "Suppose," she went on, "we'd had solid shells like mollusqs, or at least supporting frames like gigants! But I suppose the lesson to be learned is that the plastic life-forms do better in a changing environment. Once you develop rigidity you're at risk of extinction."

But aren't we? Tenthag suppressed the thought, and merely requested evidence for Gveest's amazing claim about the male and female of the folk actually being separate species.

Much of what Pletrow offered in answer, Tenthag had already partly grasped. Until he went to Bowock, he had been unacquainted with ideas like "symbiosis" and "commensalism"; however, as soon as they were spelled out in terms of, for example, the secondary growths on a junq's back, he instantly recognized how well they matched ordinary observation. And the notion of plasticity was not at all foreign to him. Since childhood he had known about creatures which seemed not to mind what part of them performed what service. If one took care not to dislodge it from the rock where it had settled, one could literally turn a sponqe inside-out, and the inner surface that had been its gut would become a mantle, and vice versa. But he was astonished by a demonstration Pletrow performed for him with a brollican, a mindless drifting creature from the local ocean, avoided by the folk because of the poison stings that trapped the fish it preyed on. To indicate how far back in the evolutionary chain symbiosis must reach, she carefully peeled one of the things apart, dividing it into half a score of entities so unalike one could not have guessed at a connection between them. Then she tossed food into the pool, and within a day each portion had regenerated what it had been deprived of.

"But if you split them up so completely, how is that possible?" demanded Tenthag.

"Because you can't split them up completely. Enough cells from each of the components enter the common circulation to preserve a trace of the whole in every segment, but they remain dormant so long as suppressor chemicals are circulating too. When they stop, the cells multiply until they once again reach equilibrium. I'll show you under the microscope."

Sometimes dazed, sometimes dazzled, Tenthag thereupon suffered through a crash course in modern biology. On the way he learned about the invention of musculators and nervograps—a web of the latter, connected to various sensitive plants, reported results from outlying pens and plots and pools—and about the buoyancy of cloudcrawlers, whose gas-distended bladders had furnished the earliest proof that air was not one substance, but a mixture, and about a score of other matters he had previously felt no interest in.

Clacking his mandibles dolefully, he said at last, "And this incredibly complex, interlocking system could be put in danger by something happening out there in the sky?"

"Ridiculous, isn't it?" agreed Pletrow. "Almost enough to drive one back to astrology! But every line we pursue leads us to the same conclusion. Now we think it may have to do with the fact that some kinds of light can burn. You've used burning-glasses?"

"Well, naturally! I grew up with them."

"But do you realize there are kinds of light too wide to see, and also too narrow?"

After proving her point with a small fire and a black filter that allowed no visible light to pass, yet transmitted heat without any direct contact, she introduced him to mutated creatures from the rest of the Lugomannic Archipelago. This was her specialty, and she waxed eloquent over the creatures she kept in pens on the north shore: vulps, snaqs and jenneqs all somehow wrong—lopsided, or looking as though one end of an individual did not belong with the other, or missing some external organ, or boasting an excess of them. Tenthag found the sight repulsive, and with difficulty steered her away from the subject, back towards the crisis facing the folk.

If anything, what she told him next was even more disturbing, for she illustrated it with cells cultured from his own mantle, and invited him to compare them with those recovered from Prefs—and then calmly took a sample of her own tegument to complete the argument. All his life, like virtually everyone in the world, Tenthag had been conditioned against bringing anything sharp towards his own, or anyone's, body. A claw-scratch, such as she had inflicted on him, was nothing, but the risk of having a major tubule punctured, with consequent loss of pressure, was terrifying; it could lead to being permanently crippled. Among glass-workers this was a particularly constant danger. Yet here she was applying a ferociously keen blade to her own side—to judge by the scars already surrounding the area, not for the first time!

Sensing his disquiet, she gave a harsh chuckle.

"They say Jing's Rainbow was deformed, don't they? It can't be too disastrous to lose a little pressure ... but in any case I've had a lot of practice. There we are! Now you can compare one of my cells with one from the female they found at Prefs. You'll notice it's far more like the male's, or, come to that, your own, than it is like hers."

Struggling to interpret the unfamiliar details exposed to him, Tenthag sighed.

"I'm going to have to take your word for it, I'm afraid. I simply don't know what to look for. Can't you tell me, though, what became of our original—uh—females?"

"There never were any," was the prompt response.

"What?"

"Females—that's to say, versions of what we're used to thinking of as females—seem to have occurred very early in the evolutionary process. But prior to their appearance, as is shown by primitive creatures like the brollican, the standard pattern was well established: clusters of simple organisms banded together for mutual advantage and shared a circulation, a chemical bath, which controlled the reproduction of them all. That, though, works only up to a certain level of complexity. If I chopped a claw off you, you couldn't regrow it, could you? And reproduction is only an elaborate version of regrowth. But—and here's the main problem—within any single organism there's always decay going on. To renew the stock, without aging, and to evolve, calls for some sort of stimulus, some infusion of variety; what, we don't yet know, but we're sure about the principle. We assume it comes from the use of the symbiotic species, whose chemical makeup is much more unlike the donor's than outward appearance would suggest. Or at least it used to be. Now we're back to the change dating from the New Star, and the latest outburst of mimicry, which seems now to be going clear to the cellular level. At all events"—Pletrow briskened, evading the subject that was closest to her pith—"there never were specific females for the folk. Our species evolved together from that stage, craws of years ago, when it became impossible for either of us to continue providing the necessary variant stimuli from our own internal resources. So to say, we'd become so completely efficient as a single organism that we could no longer be peeled apart, and identity had supplanted variety. Probably you males"—with a wry twitch of her mantle—"were essentially parasitic, but you must have been amazingly successful, or you'd never have attracted such a promising species as us females into dependence!"

Controlling himself with extreme effort, Tenthag said, "If Gveest's research is successful, and his techniques can be applied to—to us, what will it involve?"

"Modification of another permanent symbiote that will survive transmission into our own bodies by way of the food we eat, and then restore the original bud-reaction."

For a moment the scope of the plan took the air from Tenthag's mantle. Eventually he husked, "But what about numbers? Gveest himself has said it will be necessary to build up the food-supply—that he had to do it here before trying his methods on vulps and snaqs and so on. Suppose we do suddenly find we can produce buds, if not every time, then twice as often as before, five times, half-a-score times: might we not outstrip our resources?"

"Gveest plans to give us new delicious foods. You've tasted some. But in any case..."

She fixed him with so piercing a glare it transfixed him to the inmost tubule, and her voice was like a prong as she concluded:

"Let the future take care of itself! I only know one thing! I mean to bear a bud before I die!"

VI

After so long a delay that Tenthag was afraid he might lose control over Flapper, who should either have departed on a new voyage or been retamed in fresh water, Gveest emerged weary but triumphant from his laboratory to announce he had no further need of Tenthag's presence.

"We've successfully established a reproducible strain of your cells," he explained. "That will furnish us with all the data we require. You've performed an invaluable service, Master Courier! Permit us, in return, to re-equip your porp."

"Thank you, but I'm content with the growths that she already bears," was Tenthag's stiff reply. "Besides..."

He hesitated, not wanting to be tactless to this elderly scholar who was, after all, an uncontested genius and on the verge of a breakthrough which might benefit the whole planet.

Might...

It was pointless, though, trying to elude Gveest's weather-sense. Dryly he said, "You're concerned about the probable success of my work. Pietrow told me. That's why I'm disappointed that you won't let me refit your porp. Now we shall have to signal the People of the Sea and let them spread the first stage of our techniques."

"I—I seem to have misunderstood something," said Tenthag slowly.

"So you do, and I'm surprised." Gveest turned to pad up and down along the stretch of beach where they had met, glancing now and then towards Flapper, fretful at her long confinement in the shallows. "I know as well as anybody that, unless we vastly increase our food resources first, doubling or trebling the rate of budding could lead to dreadful consequences. But we're not the only people who've been working on this problem, you realize. There are outstanding scientists among the People of the Sea, just to begin with, who may be more anxious than we are for personal glorification because their traditional role has been undermined by couriers."

Tenthag clenched his mantle as the implications struck him.

"You want to start by publishing your methods of improving crops," he suggested at length.

"Naturally. But the People of the Sea don't keep farms, do they—save on certain islands that they use as temporary bases when the weather's bad? Besides, we landlivers far outnumber them now."

"Is that true? I had the impression—"

"Oh, yes. We've confirmed it over and over. Harvesting what they're used to thinking of as the inexhaustible resources of the sea, they grew very numerous indeed so long as they were benefiting from the interbreeding that followed the Great Thaw. But little by little their population has dwindled, too. Had it not, would there have been a chance to set up the Couriers' Guild, or a need to do so?"

"I've heard that they no longer recruit as many junqs and briqs as formerly," Tenthag admitted.

"They aren't there. Those are life-forms almost as advanced as we ourselves, and subject to the same worldwide problem. What we must do is publish news of what we now know how to do to mounts and draftimals—because unproved transport will be imperative—and also to the creatures which our ancestors once used as food."

He uttered the concluding words softly and with reluctance. Tenthag instantly recognized the logic underlying them, but his inmost being was revolted.

"Are we to go back to the ways of savages?" he cried. "I know folk sometimes do in the grip of famine, but for scores-of-scores of years we've fed well enough from civilized resources—"

"You eat fish and wingets, don't you?"

"Well, yes, but they're as mindless as plants! I'd never kill a land-creature for food—or a porp like Flapper!"

"We may well have no choice." Gveest was abruptly stern. "We must decide between extinction—slow, but certain—and an increase in our breeding-rate. If we opt for the latter, we must make provision to save ourselves from famine due to overpopulation. Think, think! If twice as many buds appear in the next generation, those raising and catching food will just suffice to keep us all well fed—assuming, as I mentioned, better transportation. But if the figure isn't twice, but half-a-score times more ... what then?"

Tenthag's pulsations seemed to stop completely for a moment. He said in an awed whisper, "You think your work has paid off so completely?"

"Think?"—with a harsh chuckle. "Beyond my wildest dreams! I now see how to grow a bud from every pairing!"

"This is because of me?"

"Yes, what we learned from you made all the difference. You haven't seen Pletrow the past few days, have you?"

"Ah—no, I haven't! She said she was busy with some new research, and I'm used to being by myself, so..."

"She, who never took a bud before, has taken mine, and it's a female, exactly as my theories predicted. Now will you let us re-equip your porp? I should remind you: you're bound by the couriers' oath to distribute whatever information you are given, and there are folk the world around who could learn just by looking at what we plan to graft on her a means to multiply a score of different food-plants! We want—we need to have that information running ahead of any news about transforming animals ... like us!"

A terrible chill bit deep into Tenthag's vitals, but his voice was quite controlled as he replied.

"It is not, as you point out, my place to act as censor. I'll leave that to the Order of the Jingfired. I'm amazed, though, that you want to send off one courier, not laqs of us! Surely this is something every expert in life-studies ought to hear of right away!"

"All the experts on the planet may not be enough, but if we fail ... Who'd care, if an unpeopled globe crashed on a star? We must have seen it happen countless times! Maybe the New Star itself was some such event! Come, bring Rapper to the fresh-water pool on the east coast. She will be tamer there, and you can retrain her while the grafts are taking."

And, as Tenthag numbly moved to comply, he ended, "But what I said about certain people being able, just by looking, to judge our achievement where plants are concerned, may also hold good for animals and for ourselves. The news you spread will be enough to bring the People of the Sea hither in a year or two. I hope it won't be sooner. The resources of the ocean are no less limited than those of the land, and I greatly fear what would happen were our nomads, already saddened by the fading of their ancient glory, to seize on my techniques before they understood the repercussions. For the time being, therefore, you will be our sole link to the outer world, and Bowock the sole place where all the facts are known."

"But," Tenthag confessed to the Council of the Jingfired a month later, "all Gveest's wise precautions went for nothing. On my outward voyage, beset by mustiqs, I had traded Bowocker credits for a pair of spuders, as you know. Returning, I was accosted by the same fleet, and it appears that rumors of Gveest's success had already reached them. I was faced with the choice between redeeming Bowocker credits against new knowledge—which, I respectfully remind the councilors, is the ultimate justification for their existence—or attempting to dishonor them, and Bowock, by making my escape. The fleet consisted of about a score of junqs, and a few were young and very fast. Not only would I have been trapped for certain; my action would have brought the credibility of Bowock into disrepute. I maintain I had no alternative but to honor the Bowocker pledge."

He fell silent, and waited trembling for the verdict. It was very quiet here in the Grand West Arbor of Bowock; the plashing of waves underpad, where only a mat of roots separated the assembly from ocean ripples, was louder than the distant sound of the city's business. A few bright-colored wingets darted from bloom to bloom; otherwise there was no visible motion beneath the canopy of leaves.

Until the Master of the Order stirred. He was very old, and spoke in a wheezing tone when he spoke at all. His name was known to everyone— it was Iyosc—but this was the first time Tenthag had set eye on him. For years he had been sedentary, like an adult cutinate, incapable of mustering pressure to move his bulk unaided. Yet, it was said, his intellect was unimpaired. Now was the time for that opinion to be confirmed.

"It would have been better," he said at last, "had the credibility of Bowock gone to rot."

A unison rush of horror emanated from the company. Tenthag could not stop himself from cringing to half normal height.

"But the courier is only a courier," Iyosc went on, "and not to blame. It is we, the Order of the Jingfired, who have failed in our duty. We, who supposedly have the clearest insight of all the folk, equipped with the best information and the most modern methods of communicating it, should have foreseen that a solitary courier crossing the Worldround Ocean might be accosted twice by the same squadron of the People of the Sea. Where is Dippid, chief of the couriers? Stand forth!"

Dippid complied, looking as troubled as Tenthag felt.

"We lay a new task on you," Iyosc husked. "Abandon all your others. News of what can be done, thanks to Gveest's research, with food-plants and—yes!—animals must outstrip news of what can now be done to people! I speak with uttermost reluctance; like Barratong, who forged the Greatest Fleet in the years before the Thaw, and created the foundations of the modern world, I have hankered all my life after the chance to plant a bud ... and always failed. Now it's too late. But the notion of two, three, five taking in place of one fills me with terror. Long have I studied the history of the folk; well do I comprehend how, when starvation looms, our vaunted rationality flows away like silt washing out of an estuary, to be lost on the bottom mud! Nothing but our powers of reason will save us when the claws of the universe clamp on our world and crack it like a nut! For the far-distant survival of the species, we should have risked loss of confidence in the credits that we issue. Now we are doomed beyond chance of redemption!"

A murmur of furious disagreement took its rise, and he clacked his mandibles for silence. It fell reluctantly.

"Oh, yes! There are many among you who are young enough to benefit—as you imagine—from Gveest's achievement! But are you creating the farms and fields, the forests and the fish-pens, which will be needed to support the monstrous horde of younglings that must follow? Where would you be right now, if you had to support five times the population of Bowock from its existing area? And don't think you won't! As soon as the word gets abroad that the secret of fertility is known here, won't crowds of frustrated strangers quit the countryside and the service of the sea, and concentrate here to await a miracle? We're none of us so absolutely rational as to have forgone all hope of miracles! Besides, by this time it's beyond doubt that the People of the Sea must have landed on Ognorit and appropriated Gveest's techniques."

"No! No!" Tenthag shouted, but realized even as he closed his mantle that Iyosc had seen deeper than he to the core of the matter.

The Master of the Order bent his bleary old gaze on the young courier.

"Yes, yes!" he responded with gentle mockery. "And I still say you were not to blame. You weren't brought up, any more than I or the rest of us, to react in terms such as the People of the Sea are used to. We tend to think more rigidly; we draw metaphors from rock and glass and metal, all the solid changes in the world that fire can wreak. Theirs is the universe of water, forever in flux, forever fluid. They will not heed the strict conditions we'd apply; they'll rush ahead as on the back of a swift junq, and exclaim with pleasure at the sparkle of her snout-wave. Yet some of them are clever scientists. I'll wager it won't be longer than a year before we learn that they are trading Gveest's discovery to just those poor communities which are least fitted to fill extra maws!"

VII

And those isolated settlements, naturally, were the ones the couriers must leave to last...

Obeying Iyosc's directive, the Guild mustered in force to distribute Gveest's data concerning food-plants and—against their will—animals that had once been used for food. Scores of volunteers were impressed to make more and ever more copies, enclose them in waterproof capsules, bind them to the saddles of the porps. Meantime the nervograps were exploited to their utmost and beyond; the two which stretched furthest overland shriveled and died. Therefore old techniques had to be revived, so messages were sent by drum, or tied to flighters, or to bladders cast loose on the ocean currents.

"It must have been like this during the Thaw," Tenthag said suddenly as he, Nemora, Dippid and other couriers readied their porps for departure. Dippid glanced round.

"How do you mean?"

"For the rising waters, put the People of the Sea."

"Oh, yes!" said Nemora with a harsh chuckle, giving Scudder a final tap on her flank before ascending the saddle. "Eating away at our outlying coasts, while we make desperate shift to salvage what we can on the high ground! I've always been in love with open water, but for once I wish I could be a landliver, doing something direct and practical to stem the tide!"

"There's nothing more practical than what we're doing!" Dippid snapped. "No matter how much land you cultivate, no matter how many animals you help to breed, you can't withstand the onslaught singleclawed! We must alert the world, not just a chosen few!"

"Oh, I know that." She sounded suddenly weary as she secured her travel-harness. "But I have this lust for something basic instead of abstract! I want to puddle in the dirt and watch a chowtree grow! I want to see more life come into existence, instead of darting hither and thither like some crazy winget that doesn't even drop maggors!"

Her voice peaked in a cry, and to the end of the porp-pens other people checked and gazed at her.

Tenthag, remembering Pletrow at Ognorit, said soberly, "You mean you want a bud."

"Me?" She shook herself, like one emerging from a swim, and curled her mantle's edge in wry amusement. "No, since you I've grown too accustomed to my solitary life! But what I would like is a bud from Scudder. Never was there such a swift yet docile porp, and now she's old, and I must train a new one to replace her ... Had it not been for this emergency, I'd have asked leave to try and breed her with a wild male. Probably it wouldn't take, but I'd have liked to try, regardless. As things are, however—Oh, never mind my dreams! There's work to do!"

And, shouting farewells, she plied her goad and drove the porp to sea.

Watching her go, Dippid said softly, "That's one problem I hadn't thought of."

"You mean her wanting to raise a youngling of Scudder's as a—what's the word?—surrogate?" Tenthag suggested.

"Exactly. I suspect there may be many cases like hers, as soon as the implications of what the People of the Sea are doing have sunk in."

"But they don't take porps, only briqs and junqs," said Tenthag, missing the point. "So even if they multiply—"

"Of course they don't!" Dippid retorted. "Porps are what we couriers have made our own, of all the creatures on the planet! But even before Gveest's discovery, we were looking forward to our own abolition. Have we not envisaged nervograps across the deepest oceans? Have we not heard of means to transmit images as well as symbols? And are there not scholars as brilliant as Gveest working on the idea of actual flight, with gas-bladders and musculators to carry folk aloft? Oh, I know what you'll say to that—I've heard it often from the youngest couriers! Given that our ancestors were flying creatures, we could adapt to the air! Maybe you could. Not me, not Nemora. Yet it would be something to have passed on certain skills, in navigation, for example ... But that's not what threatens us now: not simple obsolescence. It's actual disaster, the risk that in two or three generations' time there won't be enough sane folk to make new discoveries, there won't be any news to carry, there won't be any reports to publish, there won't be scholars anymore, but just a pullulating mindless mass, alive enough to breed but not well fed enough to reason and to plan."

"It cannot happen," Tenthag said obstinately.

"Don't you mean: you won't admit it's likely?"

Dippid's self-control had slipped. Meantime, silence had fallen over the whole area of the pens, and everybody was listening to the argument. Abruptly aware of anger-stink, Tenthag strove to prevent his voice from shaking.

"Even though I did let the People of the Sea redeem their credits—and nineteen in every score of us would have done the same!—I still say things won't be that bad. It calls for intelligence and planning to apply Gveest's treatment. Without that, our bud-rate will drop back to what it has been."

"But how long would it take before we could restore our food-supplies? One explosion in one generation would suffice to set us back a score-of-score of years, at least!" Dippid pulsed violently. "Have you not seen the madness due to famine?"

"No, never," Tenthag admitted.

"If you had, you wouldn't treat what you've done so casually! I saw it, when I was no older than you are now. There had been a crop-blight at the Southmost Cape. You know about that dreadful episode?"

"I've heard it mentioned, yes."

"That's not enough! You had to be there. I was among the couriers who brought away samples of infected food-plants for Scholar Vahp to study—the same Vahp who taught Gveest, by the way. And the folk were so desperate, we had to land with an escort of prongers because they didn't want us to take even a leaf, even a stalk, infected or not. They were just aware enough to remember that they needed more food, and they were prepared to fight for it. Yes, fight! Tear gashes in each other's mantles, slash each other's tubules if they could! They say everyone's entitled to one mistake, Tenthag, but it's given to few of us to make an error as immense as yours!"

"But I...!"

The attempted rejoinder died away. Turning to mount Flapper, he said humbly, "Only time can judge whether it was as grievous as you claim. Deliver my commission and let me go."

Memory of the hostility that had overwhelmed him haunted Tenthag until he was well under way. Objectively he knew that he was not at fault—Iyosc himself had exonerated him—but that didn't alter the impact he had had on the lives of his companions in the Guild ... and everybody else.

He delayed long before studying his commission, afraid it might be some sort of punishment. On the contrary: the route assigned him was through familiar waters and to familiar ports, and the tour actually concluded at Neesos. Would the People of the Sea have reached his old home before him? He dared to hope it was unlikely. They would have started by selling the knowledge they stole from Ognorit among the islands of the southern and equatorial zones; perhaps they would not get as far as Neesos this summer. He cheered up.

But his optimism faded as he made his assigned stopovers, delivering to the local savants messages concerning plants and animals. Rumor, if not precise information, had outrun the couriers; wherever he called, the folk were impatient to the point of rudeness, and tossed aside his dispatches.

"We want to bud!" they shouted. "We want Gveest's secret of fertility! There are five-score fewer of us than this time a score of years ago!" Or "two-score" or "half a score" ... but always fewer. It was in vain to insist that before more buds were brought forth there must be extra food. Even the wisest old'uns were in the grip of passion; they dismissed everything he said with a wave of one casual claw.

"We'll take more from the sea!" was a typical answer, or, "We'll go back to wild plants like our ancestors!" Sharply he said, "It looks as though you already decided to!" For everywhere he saw the symptoms of decline: parasitic weeds hanging about the eaves of the houses, blocking the sap-run on which depended edible plants and funqi; mold spoiling swatches of good fruit; clamps and copses abandoned in the surrounding countryside as all the folk converged on ports where the latest news was to be expected. The air was full of a dreadful expectation, and the reek had so permeated everyone, they no longer cared to plan for anything except that miraculous day when they too—even they—would parent buds.

Explanations of the dual-species theory met with mockery. Reasoned arguments about numbers versus resources met with boredom. Here and there a few people still remembered sanity and begged to be taken away on Flapper's back, but the couriers were forbidden to carry passengers, and anyhow it seemed better to leave them where they were in the hope that sense might after all prevail. At Klong, a month after leaving Bowock, Tenthag first encountered an outburst of religion, and trembled to the core of his pith. So dreamness could take a new grip on the folk even before the actual onset of the population explosion. Mere rumor had sufficed, at least in this one land...

He fidgeted with the urge to make for Neesos, but defied it. He must make his own obeisance to reason—his own sacrifice, whatever a sacrifice might be.

By dark especially, while Flapper broke the water into glowing ripples as she fed on drifting weed and occasional fish, he stared achingly at the sky wherever it was clear of cloud and wondered about voyages across space. Were there living creatures in that ocean of oceans? Watching a comet bloom out of a dim and distant blur, it was hard not to make comparison with a plant sprouting under the influence of summer. Marking the dark-by-dark progress of the planets, it was tempting beyond belief to imagine other beings capable of transforming inert matter into something that could feel, and react, and devise and plan and—make mistakes...

In ancient times, he had been told, some folk held that when the welkin shed its fleeting streaks it was a means of signaling, which no one here below could understand. With all his pith he wished he could send back a message of his own:

"Help us, strangers! Help us! We're in danger!"

Budded in the year called Two-red-stars-turn-blue, Tenthag sought comfort in the unaltered patterns of the sky, and found none. For they weren't unaltered.

As though to harbinger the shock the folk must bear, the dark before the bright that saw him at his bud-place was lighted by a singular event.

One of those very stars, on the fringe of the Major Cluster, which had gone to blue from red, changed yet again. A hint of yellow touched it. It seemed brighter ... but a cloud drifted across it, and there was no way of being sure about the outcome before dawn.

VIII

But where was everybody?

Goading Flapper into the bay that covered the site of Prefs, Tenthag surveyed the vicinity with his telescope. Normally by dawn the fisherfolk would be launching gorborangs, and sand-collectors loading raw material for the glass-furnace. Because it had been so long since he left here, he had been prepared for some changes, but not for this feeling of vacancy which set his weather-sense to full alert.

Leaving the porp to browse, he waded ashore carrying the last of his copies of Gveest's food-data. As soon as he was clear of the water, he shouted with all the force of his mantle.

There was no answer.

Becoming more and more alarmed, he padded along familiar tracks— how often had he come this way with Fifthorch, to swim from the gentle beach and sometimes dive for relics?—noting with dismay how well-tended clusters of food-plants had been let run wild. He came across sleds of the kind used to bring home sand, abandoned by the path; creepers were twining over them in a way that indicated they must have been dumped a moonlong ago, at least. And his forebear's mirror, source of Neesos's prosperity, was pointing at nowhere.

Shortly, breasting a rise, he came in sight of the little town at the center of the island, sheltered in a hollow against the worst of winter weather. Here at last were people, though nothing like as many as he would have expected. Draped on slanting branches, or lying under rocky overhangs for protection against the morning sunlight, they were listening to someone talking in a loud rough voice. Before he drew close enough to make out what was being said, Tenthag had already discerned that they were surrounded by all the goods they could assemble, be it foodstuffs or glassware or seed-stock or objects salvaged from Prefs.

Something prompted him to great caution. Lowering to minimum bearable height, he stole among shadows cast by bushes until he reached a rocky niche where he could look on unobserved. Fortunately the wind prevented anyone from scenting him ... but the stink it bore to him from the crowd was enough to make him quail. It uttered a whole history of greed and jealousy, and the speaker at the middle of the group was fomenting it.

And the orator was—

Recognizing him, Tenthag was almost snatched by dreamness. It was Fifthorch.

Who was saying, "—so of course they want to keep the secret for themselves! It's lucky for us that the People of the Sea aren't under the pads of the Bowockers and their precious Order of the Jingfired! Jing was never real! Jing was a figment to keep young'uns quiet! Well, some of us grew out of childhood tales! I wish we all had! The fact that supposedly adult people right here on Neesos still claimed that the Jingtexts must be truth—until we drove them out as they deserved!—isn't that enough to curdle your maw? It certainly did mine! Be thankful for the People of the Sea, who are coming to our rescue! I'm sure we've brought together enough goods to make them give us the secret of fertility! They care about the fact that we've been left without a single new bud since traitor Tenthag ran away! They aren't cold and cynical and cruel like the Bowockers, who weren't content to take our most valuable possessions from beneath the Bay of Prefs, but stole our youngest young'un as well! And what did they leave in exchange? Rubbish! Scraps and oddments any one of us could have got by making a voyage to the mainland! Things you trade for common seed or common glass! Not glass like ours, the finest on the planet! Did they offer musculators and nervograps? Did they give us anything useful? No, they robbed us of what we didn't even realize we owned, and laughed when they went away! Taking our last new-budded youngling with them, what is worse!"

His memory echoing with Nemora's comment about the archeologists who were far too mercenary for her liking, Tenthag found that more than he could endure. Rising to normal height, he padded forward, shouting, and all eyes turned on him with amazement ... save for Fifthorch's, which was full of hate.

"I never dreamed you'd miss me so much, Fifthorch!" he roared. "Did it not suit you to become the youngest when I left—not stolen, but of my own free will?"

His diet of yelg, in spite of his lonely and inactive life aboard a porp, kept him fit and well pressurized; he was able to overtop Fifthorch without effort. Taking station higher on the branchway, where he could continue to dominate the other, he filled his mantle with air for the loudest possible shout. These people looked as though they needed to be startled back to reality.

But a shrill voice took the pressure out of him with a single question.

"Are you one of the People of the Sea, who are going to show us how to breed again?"

He turned, seeking the source of the inquiry ... and was instantly deflated.

"Ninthag!" he blurted, scarcely recognizing the old, bloated, half-blind shape that clung to a slanting bough befouled with tatters of wild orqid— colorful, but unfit for food. "Ninthag, don't you know your own sole bud?"

"Are you pretending to be Tenthag?" the old man wheezed. "I'm not such a fool as to believe you! He went away, long, long ago, stolen by the Bowockers! I see him in visions now, and he's laughing at us—laughing at the poor folk he left behind while he rejoices in the best the world can offer! We stay here, wondering when if ever another bud will come among us, and—Keep away from me!"

Tenthag was scrambling towards him, but on the instant half a score of others rose to block his way. Their exudates took on the taint of combat-stink.

Slowly Tenthag retreated, recognizing what he had encountered at Klong and sundry places since. These folk were starved into dreamness ... of their own volition.

He said, "Aren't you ashamed to deny your own? Fifthorch knows me—why don't the rest of you?"

"We know what we want to know," said one of them, and there was a rumble of agreement.

"But you can't! You're underfed, you're going crazy! Yet there's food all around you!" Tenthag clenched his claws in impotent rage.

"We have to keep everything we can spare to trade with the People of the Sea," said Ninthag obstinately. "Who knows how much they'll demand for the secret of fertility? We must be sure that there's enough."

"But here I am, who was at Ognorit where the secret was discovered, and I bring data due to Gveest himself—free of charge!"

With that shouted boast Tenthag broke through their apathy. They reared back and gazed at him with pitiable eagerness. Even Fifthorch was taken off guard, and gapped his mandibles.

"Is it truly you?" whispered Ninthag, staring wearily. "Your voice, your scent ... But it has been so long!" He summoned a last trace of his old authority. "Show what you've brought, then! Not to me, for my sight has failed. Where's Thirdusk?"

"He betrayed us!" shouted Fifthorch. "He fled with the cowards who were prepared to let Neesos die!"

That statement made everything clear to Tenthag. He could picture how it must have been: one faction, the more rational, counseling that life go on as normal, with enough food eaten and enough new crops planted for the next year; the other so obsessed with the lack of new buds as to forget the need to provide for them if they happened, ultimately seizing the goods of their rivals and driving them away. It was much like what had happened at his other ports of call. But in his pith he had hoped that his own homeland might be a little different, a little better...

He'd been wrong. He knew that even as he proffered the documents he had brought, and a half-score of greedy eyes fixed on them as Fifthorch spread them out.

"There's nothing here to touch the folk!" the latter yelled. "It's all to do with plants and animals!"

"But if there's not enough food—"

"We manage well with half the food we used to gobble! We must save the rest to pay the People of the Sea! You're a coward like Thirdusk! You're a traitor!"

All at once they were pelting him with insults and trampling his precious message underpad. He could do nothing but turn and flee, or they would have torn him torso from mantle in their fury.

Luckily—luckily!—they were too weak to overtake him on his way to the bay where he had left Flapper. By the time he stumbled into the shallows, he also was weakened by his efforts, and his perception was diminished. Had it not been, he would have reacted to what was happening on the skyline before he remounted his porp and turned her seaward.

Only then, though, and much too late, did he realize what was looming towards Neesos.

Here came the visitors the relic of the folk were waiting for: five junqs, four briqs, with bright banners on poles to tell the world—

WE HAVE THE SECRET OF FERTILITY! AND IT'S FOR SALE!

He crumpled on Flapper's saddle, utterly dispirited, and offered no resistance when they detached him from his travel-harness, dragged him aboard the commander's briq, and lashed Flapper to her side with yells of triumph.

He was too busy mourning for a world that never was.

IX

The commander of this raggle-taggle fleet still wore ancient symbols of rank on thongs crossed about his body: a spyglass lacking its objective, a briq-goad worn to a stump. Crusty-mantled from bad food and long exposure to the elements, he interrogated Tenthag about Neesos, wanting to know whether any folk were left, or whether they had all fled as from so many other lonely islands.

"They might as well have run away," was Tenthag's bitter answer. "They took leave of their senses long ago. But why ask me? I'm just a visitor, and there they are who can answer for themselves!"

He pointed. Those who had rushed in pursuit of him were milling about on the beach, amazed at the sight of the fleet, and he could almost hear the arguments over who must return to town and collect trade-goods.

"Hah!" said the commander with satisfaction. "Let's go see what they can offer worth the taking! You!"—handing a prong to a nervous she'un—"keep watch over him, hear me?"

And, surrounded by his sub-commanders, headed landward.

More miserable than ever, Tenthag was compelled to look on as the Neesans delivered everything they owned for the visitors' inspection. Meantime, however, a suspicion began to gnaw at the back of his mind. At first he was too despondent to react; by degrees it overcame his depression, and he roused himself enough to survey the close-clustered briqs and junqs.

They still bore their complement of old'uns and she'uns. But not a single one among the latter was in bud...

The monstrosity of the deceit these nomads were perpetrating stabbed him to the pith, and he almost made a leap for Flapper. But the she-guard was ready to spike him, and he was in no hurry to become an underwater banquet.

He must match their deception without giving off a betraying odor, therefore. Would anger-stink cover up a lie?

Well, by now experience had made him cynical enough to try...

He and the guard were isolated near the briq's after end; the rest of her riders were gathered forward. He said softly, "What's your commander's name?"

She hesitated; then, finding no reason to refuse the information, muttered, "He's called Sprapter."

"And he is a good person to serve under?"

"He does well by us. He's clever. The proof's around you." Her tone was curt, but uneasy, as though she feared a trap.

Tenthag saw nothing special about the accoutrements of the briqs and junqs—indeed, they could have been matched by any kyq from his youth, and the latter would have been set about with useful gorborangs, as well—but now was no time to be patronizing. He said hastily, "And you are ...?"

"Veetalya."

"Do you believe it to be part of Sprapter's plan that I must parch to death?"

Taken aback, she said, "You heard his order to me!"

"So I did. It made no mention of my being denied water. Oh, I know the People of the Sea hate us couriers nowadays, but our lives have much in common, and I take it that if Sprapter ordered you to guard me he'll expect to find me fit and well when he returns,"

Alongside the briq Flapper was growing restive, as always in salt water. Why had they not turned her loose, or stripped and killed her? Did Sprapter cherish grandiose dreams of adding a porp to his little fleet? Or did he think she might prove useful for trade purposes when they headed south in search of the secret they claimed to possess, but did not? Whatever the reason, it was a stroke of luck. Tenthag said in his most wheedling tones, "Your drink-bladders are bulging, aren't they? And if there's one thing a porp lacks, it's adequate drink. A briq is far superior in that regard. You People of the Sea know ancient tricks that we ought really to have studied, but of course, as you know, we tend to be arrogant. With a few exceptions, like myself for example. But isn't that a fault you too display?"

She was nervously tightening her grip on the prong. With a reflex glance at the drink-bladders, she said, "I don't know what you mean!"

"Oh, it's plain as sunlight! You're not in bud, although your folk possess the secret of fertility, and I can only explain the fact by assuming that you angered Sprapter, and he refused to let you have a bud until you'd made amends for some offense you'd given. Well, if you give me drink, I'll speak up on your behalf when he returns."

By this time, as he had dared to hope, she was thoroughly confused. Providentially, a shout rose from the beach at the same moment. The distance was too great for Tenthag to make out exactly what was being said, but a fair guess suggested that one of the Neesans had complained about all their best possessions being taken, and one of the visitors had demanded what price was too high to pay for fertility.

The same might be asked concerning freedom. Accustomed, like almost everybody else, to imagining that the risk of being stabbed through a major tubule was sufficient to make anyone sit quiet, Sprapter had relied on Veetalya's possession of a good sharp prong a padlong distant to ensure his captive would obey her. But he had seen Pletrow calmly cut her own body with a far keener blade, and heard her casual dismissal of the risk...

"Oh, come now!" he said, as Veetalya glanced towards the row on shore, and took a stride that brought him within the range of her prong. "A drink is not too much to—"

And snap. At maximum pressure his claws closed on the prong and broke it off, and he was all over her, trusting to his greater weight to force her backward. She wasted her spare pressure on a scream, and that sufficed. He trampled on her as though she were not there and swarmed over the briq's side into Flapper's saddle, which the People of the Sea had not found time to dismount. With claws and mandibles and the stub of the prong he slashed at the bonds restraining her, and before the startled crewfolk at the forward end could get to him, he had weakened them enough for the porp to break the rest with one great heave and surge. Half-swamped in a deluge of water, he clung valiantly and jabbed her back with the prong in lieu of a goad. With all her well-fed force she rushed for open water, leaving his captors to fret and curse and hurl obscenities.

The breeze bore him one furious shout: "Well, a courier's no loss to us, any more than a porp!"

Wrong, promised Tenthag silently. I'm going to cost you more than you can possibly afford!

After so long a period of forced inaction, Flapper rushed straight for the horizon, and he let her go, glad that his provisions had not been pilfered. He drank a lot and ate a little, restoring his normality while calculating how long it would be before the trading on the beach came to an end. If tradition were anything to go by, it would last until dark, and some kind of celebration would follow. The People of the Sea would not dare risk departure without the regular formalities, or even in their debilitated state the Neesans might suspect the trick that had been played on them. Therefore he should have time to swing around on a long circular course and bring Flapper back to the island just after darkfall, when her return was least likely to be noticed.

Cold anger colored his mind gray. Stark facts like distant mountains marked the boundary of his thinking. He was possessed, for the first time in his life, by lust for vengeance.

As darkness fell, he sought the star which had caught his attention at the fringe of the Major Cluster. There was no mistake. It had turned yellower and brighter. Perhaps someone who had not watched the sky from the lonely vantage of a porp's back in mid-ocean might have overlooked the change, but to Tenthag it was past a doubt.

In ancient times they'd said the stars reflected what went on below. He was too well informed to swallow such deceits. But the image, nonetheless, was powerful, and struck chords in that level of his mind where dreamness ruled.

Perhaps that star was shedding bright new light on what had been dead planets, conjuring the force of life from them. It didn't matter. For him it was a symbol, and a challenge. He must cast light of his own on his own folk...

Luminants faintly outlined the island, but there were wide gaps where they had not been properly tended and he was able to steal ashore without being spotted. He left Flapper to fend for herself. If he came back by dawn, she would probably still be here; if not, she would shed her saddle as soon as it rotted, but with luck keep the secondary plants Gveest had bestowed on her, which would be an example to any other of the folk who ran across her later on. Maybe, if she bred in the wild, some of them might cross-take on her bud...

Who, though, would help the porps if the Guild of Couriers all met the same doom as Tenthag? In a few years, following the population explosion, they would surely be hunted down for food!

Repressing all such horrible previsions, he crept over the hill-crest on which stood the derelict solar mirror, and found his guesses accurate. Reluctant to leave before sharing refreshment with the local people, the visitors were sitting under arbors of luminants and pretending to be polite. Fifthorch, recognizable by scent and voice, was lavishing on them what food and liquor remained, while others waited in shadow, exuding the stink of greed ... or was it from the outsiders? At this distance he could not be certain.

But that was irrelevant. Hastening down the old familiar path, he headed for the crowd—and was brought up short, so that he clutched his sole weapon, the broken prong, and spun around with a hiss of terror. He had abruptly caught a waft of death, and there were overtones to it that he recognized.

Beside the path, clearly having collapsed as he moved away from the town, leaking his stale ichor on the ground after a major rupture of a lower tubule ... Ninthag.

He who had been the town's elder for so long, its guide and counselor: left here to rot unheeded! Had he been stabbed? But a quick tactile check confirmed that he had simply died from stress. Well, that was a relief, of a sort—but still an insult!

Tenthag drew himself together and put on the best imitation he could contrive of his father's appearance. Maintaining it, while imitating an old'un's hobble, he let himself show in the circle of brightness shed by the town-center lights.

It was Sprapter who first noticed him, accepting a shell of araq. He was so startled that he tilted it and cursed as the biting liquid spilled down his torso. Before he could speak, while others were still turning to gaze at him, Tenthag said loudly enough to be heard by everyone, "Have they shown you a female with a bud?"

Fifthorch, offering more araq to another of the People of the Sea, started so violently he almost slumped, and Tenthag, still posing as his father, padded towards him. In a thin voice he repeated, "A female with a bud—have they shown you one?"

"Drive him off!" Sprapter cried, struggling to full height.

"Why?" Tenthag countered. "You have the secret of fertility, or so your banners claim! That means you must have buds and young'uns in your fleet!"

"Of course they have the secret!" Fifthorch shouted, while the hunger-sluggish minds of those around him registered what Tenthag was saying. "They've sold it to us, and on fair terms, what's more!"

"But have they shown a single young'un, or a she'un budding?" Tenthag abandoned his disguise and strode to take station at Sprapter's side, his prong leveled. "I say they haven't even met the southern fleets which raided Ognorit, but stole everything you could offer in the hope that when they do they'll get the secret! Truth, Sprapter—tell the truth!

And for every lie I'll let the pressure out of one of your tubules!" He jabbed the commander's torso, just enough.

Terrified, Sprapter babbled, "I swear we would have kept our bargain! We needed to buy the secret and we'd have come back and—"

"You mean you didn't give it to us?" Fifthorch said, belatedly reacting to the commander's reek of guilt and shame.

Without compunction Tenthag slit a minor tubule in the trickster's torso, forcing him to fold over and compress the leak until it sealed.

"I don't know what they clawed off you," he said mildly, "but as I tried to tell you earlier, I was at Ognorit, and learned from Gveest himself what must be done. On the briq where I was captive, I met a she'un who was ripe for budding, and she had no bud. I saw not a single bud or young'un in this fleet that claims to sell the secret! What do you make of that, you fools who left Ninthag to leak away his life on that path yonder? Who'd have the secret merely to sell to others, without using it to benefit themselves?"

A pulsation later he was frightened by the forces he had loosed, for Fifthorch roared with mindless rage and launched himself at Sprapter. Before the two could be separated the commander was as dead as Ninthag, and the air was foul with the stench of drying ichor and loud with screams of pain.

But within moments the seafolk were cowering to the ground, emitting the odor of surrender, and finding themselves about to slash or stab with whatever weapon came to claw, the Neesans recovered enough of their normal awareness to realize what they had done, and be horrified at it. Weak, but calm, they began to mutter among themselves that Tenthag had been right, and they were stupid not to have insisted on being shown a budded she'un before parting with their goods.

Suddenly Tenthag found them all looking to him for guidance, seafolk and Neesans alike ... except for Fifthorch, who faded into the dark moaning about the need to wash off Sprapter's ichor.

He said after a pause for reflection, "Eat what there is. Give nothing more to the seafolk. You must restore your strength of mind and body both, because you're going to make these liars pay for their deceit. Not only are they going to return what they cheated you out of; they're going to be set to work recovering the plants you've let run wild, ridding the town of mold and orqid, bringing fish from deep water, and laying up great stores of food against the time when the real secret of fertility is brought hither. It won't be long, I'm sure. But there must be food first!"

The seafolk whispered among themselves. Eventually one sub-commander rose to normal height.

"It's fair judgment," he admitted sullenly. "I'm Loric. I've been chosen as Sprapter's successor. I'll abide by your terms, but I'll ask one thing in return."

"You don't deserve anything," Tenthag snapped. "Feel free to ask, though, as I shall to refuse."

"You do owe me something," Loric insisted. "Sprapter wanted to kill your porp, or at any rate drive her to open water. But I've been in charge of our food-plants for years, and I saw new ones on the porp which gave me ideas. That's why I insisted on her being lashed alongside the briq. I wanted to study and adapt them. They told us that was how you were able to escape, though I must admit none of us expected you to return. It was a brave thing to do, and your countryfolk ought to be proud of you. Instead, they described you as a traitor and a runaway, especially Fifthorch, and in the end they made us believe it, so you took us completely by surprise ... Don't you owe me something, though, for saving your porp?"

"I guess so," Tenthag admitted gruffly. "Very well. When you leave here, which won't be soon, you'll have grafts of Gveest's new food-plants to help you on your way. But it may take months before there are enough for both Neesos and your fleet, and in spite of being foolish my people are still my people, and they get first call. By that time you'll have learned a lot about food-plants on land, I promise you."

"You're an honest man in spite of being a courier. You won't regret striking this bargain. How do you think I was able to persuade your folk that we did truly have the secret of fertility? Could I have convinced them without considerable understanding of all sorts of life-forms? Oh, I'm not a Gveest; I'm more the practical type. But if there's any connection between his work with plants and lower animals, and what he's discovered that will make us breed, then don't be surprised if I figure out the secret for myself eventually. I'd like to, obviously. It'd save us a trip south, into waters where there are already too many of us for the junqs and briqs available, not so?"

It was impossible not to be won over by this fellow's audacity. Tenthag tried to stop himself quirking into a smile. Loudly he said, "Work, then, if you want to clench the deal! We have two funerals to conduct immediately. Then we must tell the rest of your company the fate in store."

X

What Tenthag was doing was not in accord with his commission; he should have returned directly to Bowock. But after the hostility he had met on the day of his departure, he was in no hurry. Besides, his actions were consonant with his courier's oath, at least in his opinion. By summer's end there would be at least one fleet—small, admittedly—in possession not of the secret of fertility but of information far more essential, which it could then trade to supplement the couriers' efforts. And the seafolk would need to trade if they did begin to multiply; one bud per she'un would require at least two extra briqs or another junq, complete with food-plants, and this far north there were few young wild'uns nowadays.

He occupied himself not only with supervising the restoration of Neesos's fortunes, but with retaining and exercising Flapper, whom he took to sea almost daily with the fleet on its fishing-trips. Once they had grown resigned to the failure of their intended fraud, the seafolk proved to be friendly enough, and of course they had far more in common with couriers than they were usually prepared to admit. In the end even Veetalya recovered from the shame she felt at having let Tenthag escape, and their relations became very friendly. Loric, too, turned out to be likable, and interested not only in life-study but star-study also. Together they pondered the possible meaning of that star which almost nightly shone yellower, brighter, hotter. Through a good telescope it could be seen to be surrounded by a sort of aura, like drifting smoke.

"That's some of the cold matter massing to block our way to the future," Tenthag explained soberly. "But before we get that far, more of it will doubtless turn into stars, more will be drawn into our own sun, more will tumble out of space and crash into the oceans, raising huge waves, or smash down on land and burn forests to ash ... Oh, Loric, we are caught in a trap worse than a gigant's claw! On the one side, the risk that there won't be enough of the folk for us to save ourselves; on the other, that there may be far too many!"

"Don't you think we'll make it?" Veetalya asked timidly.

Tenthag shrugged with his entire mantle. "When I see what we can do when we combine our efforts, as here on Neesos, I feel very optimistic. But when I remember how nearly my own people went insane, and how you tried to take advantage ... Who can say?"

Turning the telescope curiously in all directions, for it was superior to any he had used before, Loric suddenly stiffened.

"Another fleet!" he whispered. "Look! See the glimmer on the water?"

"Where...? Oh, yes! Give me the telescope ... But those aren't junqs or briqs! They're porps—you can tell by the way they move! And none but couriers use porps, and that must be half the complement the Guild can boast! Quick, to the beach, and signal!"

As he incontinently led the way, hoping no loose rock would betray his steps in the dark, he wondered silently what disaster had brought this about.

Within a very short time, as all the folk of the island gathered on the beach, he learned the terrible truth. First to land was Dippid himself, followed by Nemora, and then another score of his friends and colleagues. When they had got over their astonishment at finding Tenthag alive and well, they told their story.

"We thought you must be dead," Dippid rasped. "Many of the couriers have been attacked for not possessing the secret of fertility, by people convinced they did but were holding out for the highest price. It's a rumor started by the Major South Fleet. Iyosc was right; they did raid Ognorit and now they're trading what they're pleased to call 'the right to bud' ... against everything they can lay their claws on, especially seed and food-plants!"

Tenthag exchanged glances with his companions, who by now included Fifthorch. He said slowly, "What's the situation like at Bowock? Have you been driven away?"

"Yes," was Nemora's simple answer, and she turned aside in grief. Dippid amplified.

"Iyosc was right about that, too. She'uns in bud and their companions, deprived of all their food-stocks by the greed of the People of the Sea, naturally started heading for the cities, not just Bowock, but any place where it looked as though there were still plenty of victuals. Bowock has been the chief magnet, obviously, because of that rumor that we were withholding the secret. And I regret to admit..."

He hesitated. Recovering, Nemora said curtly, "Some of the Jingfired betrayed their trust. Either they got hold of Gveest's technique, or they were able to work it out from what was already known. Anyhow, they applied it to themselves. It was impossible to keep that secret. As soon as the news got out ... Well, you can imagine its effect. We clung on as long as we could, but when we learned that couriers were being hunted down and killed we decided to flee. I remembered coming to Neesos, all those years ago, and as near as we could calculate we believed it must still be well beyond the sweep of the Major Fleet. Besides, the closer we got, the more we heard rumors that the people of lonely islands like this one were abandoning their homes and making for mainland cities, where the bud-right might be theirs all the sooner."

"Some of the folk did leave here," Tenthag muttered, and went on to explain what he had found on his arrival.

"You were very sensible not to return to Bowock," Dippid pronounced at last. "It may not have been what you were supposed to do, but it's turned out for the best."

"Do you have the bud-secret?" Loric demanded suddenly.

There was a pause like the interval between the lightning and the thunder. At last Dippid heaved a sigh.

"Yes. We had to bring something we could trade for food."

"That's liable to draw crowds of crazy folk to Neesos, then!" cried Fifthorch, indicating how much he had learned about the real world since Tenthag's return. "We must think of ways to defend ourselves—"

"We must think of ways to feed ourselves," Tenthag corrected stonily. "Sane, well-nourished folk are always our friends and allies. Only the crazy ones are a threat. And now we have a vast stockpile of precious knowledge; couriers are as well informed as anybody short of the Jingfired themselves, or scientists like Gveest. Is there news of him, by the way?"

Dippid clacked his mandibles. "Report has it that he and Pletrow and the rest are captives with the Major Fleet. But nobody knows for certain. It may just be another rumor put about to encourage folk to pay extortionate prices."

"I hope for his sake he's not," Tenthag said softly. "I got to know him pretty well while I was at Ognorit, and I'm certain he would be horrified to see the dreadful impact his discovery is having. He knew about it, he tried to guard us against it, and through ill-luck I was the one who was obliged to undermine his precautions."

"Iyosc forgave you for that," Nemora said, laying a claw friendly on his mantle-edge. "And what you're doing here is making further amends. What's more, perhaps the star—"

"We've been over that!"—morosely from Dippid. "More likely it's a harbinger of catastrophe, like the old New Star."

"It can't be! It's not at all the same!" Nemora hunched forward. "We know the other one outshone the Major Cluster, to begin with. No, I think this is more likely a stroke of good fortune. Changes like that going on in the sky are just what people will need to keep reminding them of Jingtruths. Things must have been equally bleak when the Northern Freeze began, and again at the time of the Great Thaw—yet here we are, and we have some achievements of our own to boast of!"

"There's no comparison," Dippid maintained. "This time we're breaking the very mold we were cast in by our evolution!"

Tenthag thought of Pletrow's collection of mutated animals, and shuddered as the chief courier went on.

"No, it's going to be a different world. Even during the famine at Southmost Cape I never saw anything as horrible as what's now happening at Bowock. For all we can tell, there's something in the radiation from the stars that drives us crazy now and then, and what can we do to withstand that? Grow a roof over the entire planet?"

"What use would a roof be against what's sure to fall on us one of these days?" said Tenthag wearily, and forced himself to full height. "No, we dare not try and hide from our doom. The universe will not permit it. We must carry on somehow, preserving at least a nucleus of reason ... There's a tale about the legendary Barratong. When he realized the Thaw was bringing more and more of the planet under his people's sway, he didn't rejoice or boast about it. He accepted the duty which the past had laid upon the present. Do you remember what he said?"

"Of course," said Loric as he also rose. "All we People of the Sea are brought up to regard it as the finest principle of our heritage, though since it led to the foundation of Bowock and the Guild of Couriers— Never mind! This is not a moment for squabbling over what's past and done with. Barratong said, in fact, 'We are the Jingfired now!' "

"It's our turn to say the same," said Tenthag, and padded miserably away towards the first glint of dawn, wondering how much sorrow and insanity the sun must shine on before the folk recovered from the shock of being multiplied.

And if they would.

PART FIVE

BLOOM

I

The city of Voosla was allegedly approaching her landfall, but Awb could scarcely credit it. There was too much dark on the horizon.

Wherever there was habitable ground there were people, and even more than food-crops the folk cultivated plants which, after sundown, either glowed of their own accord or gave back the light they had basked in earlier. Troqs who had taken to caves for refuge in desert regions where houses would not grow, squimaqs who eked out their existence around the poles where darkness could last for half a year—they knew that trying to manage without luminants was to risk being driven into dreamness as certainly as by starvation, if not so quickly.

And indeed, throughout the voyage until now, there had always been distant glimmerings: nothing like as bright, of course, as the lights of the city, but discernible with even a crude telescope like Awb's, which he had made himself and was very proud of. Thilling the picturist had ceded him a couple of lenses too worn for fixing perfect images, and fitted into a tube they afforded a view of the strange northern coasts they were paralleling.

However, they also showed, much too plainly for comfort, that blank gap on the edge of an otherwise populous continent. There was something so eerie about it that it made his weather-sense queasy. He found himself longing for the familiar scenery of the tropics which, since his budding, the city had never previously left.

To think that one new moon ago he had been beside himself with excitement at the prospect of this journey to the intended site of the World Observatory...!

Swarming along the branchways in search of distraction, he shortly discovered that a crowd had gathered on the lookout platform at the prow, including most of the delegation from the University of Chisp. Their chief, Scholar Drotninch, was conferring with Mayor Axwep.

Awb also found it disturbing to have so many foreigners traveling with them. Voosla was by no means a large city, and he knew all her inhabitants at least by sight. Before this trip he had been used to meeting strangers, if at all, by ones and twos, not scores together. Still, the scientists were polite enough, and some—like Thilling—were positively friendly, so he decided to chance a rebuff and draw close enough to overhear.

And was considerably reassured by an exchange indicating that he was not alone in worrying about this unnaturally lightless shore.

"Amazing, isn't it?"—from Drotninch. "Last time I came up here, this was the brightest spot for padlonglaqs."

To which Axwep: "The city's growing fractious, as though she senses something amiss. Could be a taint in the water; we're well into the estuarial zone. I'd be inclined to hold off until sunrise. It won't mean too much of a delay, and it'll give us a chance to feed and rest the musculators. I can send a pitchen ahead to explain why we aren't landing at once."

Drotninch pondered, and one could almost scent her indecision ... but, like most landlivers nowadays, she coated her torso with neutralizing perfumes. It had become a mark of good manners, and those—as Awb knew from his few visits to shore—were far from a luxury in the overcrowded conditions of a fixed city. Life at sea, in his view, was superior; if Axwep noted an accumulation of combat-stink she needed only to consult her weather-sense about what course to set and let a fresh breeze calm things down.

Finally the scholar signed agreement, and Axwep issued the necessary orders. The group dispersed, some to tend the musculators, others to prepare the pitchen. Slowly, owing to her colossal bulk, the city ceased to thrash the water. The group of interlinked junqs around which she was built exuded relief, for even in calm weather they disliked being brought near land, perhaps owing to some ancestral fear of being stranded on a beach or dashed against rocks. Not, naturally, that they could do anything against the resistless force of the musculators.

When it was uncaged the pitchen seemed equally unhappy, as though it too were alarmed by the dark shore, but that was fanciful nonsense, since it did not depend on sight—indeed it possessed no eye, and reacted solely to magnetic fields, like the ancient northfinders which had died off during the Northern Freeze. When it was dropped overside with Axwep's message tied to its claws, it set out obediently enough for the place it had been conditioned to regard as home, leaving patches of phosphorescence to mark each of its leaps. Watching it go, Awb reflected what a benefit its kind had proved to be, especially since they had been modified to follow canals and winding inland channels as well as pursuing a direct course across open water. He wished he knew who had been the first to domesticate pitchens, but during the Age of Multiplication people had been much more concerned with staying alive and sane than with keeping records of who invented what.

"That's much better!" said a she'un's voice behind him, and he lowered reflexively as Thilling swarmed down an adjacent branchway with, as ever, her image-fixer at the ready. "Maybe now I'll get the chance to cut a few new lenses! I've lost count of how many got spoiled when a wave disturbed me while I was trimming them, and I do so want to catch everything that happens when we go ashore ... And what's wrong with you, young'un? You seem worried."

"I never saw a coast so dark before!" Awb blurted.

"Hmm! I did! Once I was sent to cover an epidemic on Blotherotch— went in with a medical team looking for the causative organism, assigned to picture the victims for future reference. Some of the folk there had turned so dreamish, they imagined they could prolong their lives by eating luminants, and they'd absolutely stripped the area. It was ghastly. Still, we got away safely, and now we're all immune against that disease. On the other claw..."

She hesitated. Greatly daring, he prompted her.

"Oh, I was only going to say: we've discovered cures for so many disorders including infertility, it seems incredible there should be a brand-new one, least of all one that can afflict an entire countryside— people and animals and plants as well!"

"Is that really what we can look forward to finding?"

"You're asking me? I never set pad here, haven't even had a sight of the nervograp messages that got through before the link failed. Phrallet must know more about those than I do; doesn't she tell you anything?"

"As little as possible," Awb muttered. He was always embarrassed when someone mentioned his budder, who flaunted her five bud-scars in a manner most people regarded as indecent and seemed to think that because Axwep only had four she had the better claim to be Voosla's mayor.

"Well, you should pester her more," Thilling said, loading a sensitive sheet into her fixer. As much to herself as him, she added, "I wish I'd had tune to graft a new lens on this thing, because I'm sure there's a saltwater blister somewhere, but with dawn so close I'll have to make do ... Keep your eye skinned, young'un. If what I've been told is reliable, we should be in for a treat. Look yonder, where I'm pointing."

Awb complied, but still all he could make out, even with his telescope, was a vague patch of black-on-blacker. In the south-east the first hint of dawn was coloring the air, not nearly enough as yet to dun the Arc of Heaven, let alone the Major Cluster. There was a bank of dense cloud to the north, veiling any aurora there might be, and that surprised him, for visibility in this region was reputed the best in the hemisphere; why else choose it for the World Observatory?

On the other claw, no place on the planet was immune from what happened next. A streak of yellow light slashed out of the east, and at its tip a fireball exploded, scattering trails of luminance across a quarter of the welkin. Caught by surprise, Thilling uttered a curse.

"That's spoiled my leaf good and proper! Young'un, keep looking, and warn me if I'm apt to miss anything!"

Hastily she threw away the sheet she had been mounting in the fixer, and peeled another from the stack.

By this time Awb was beginning to guess at what she meant. The flash of the meteor had revealed something outlined against the northern clouds. He had had too brief a glimpse to make out details, but there was only one thing it could be: Fangsharp Peak, on top of which the observatory was being grown. Of course, since it was so much higher than the surrounding land, it was bound to catch the sun's rays first. So—

"Quick!" he cried, suddenly aware that all about them the branchways were alive with folk scrambling to seek a vantage point and watch the unique spectacle. Barely in time Thilling leveled her fixer.

The sky grew brighter, though the land and sea remained virtually featureless. The world paused in expectation. And there it came!

On the very crest of the mountain, so high above them that it looked as though a huge and jagged rock were floating in mid-air, a single shaft of sunlight rested.

It was the most awe-inspiring event that Awb had ever seen. Without intention, he found himself counting his own pulsations to find out how long the sight would last: three, four, five, six—

It was over, and the sky was turning daytime blue, and he could see the whole mountain. Its flanks were scarred where the natural vegetation had been stripped away in favor of what would be needed to support the observatory. Guide-cables for construction floaters swooped down to either side. A passenger-carrying floater, five bladders glistening, was descending slowly from the top. Awb had never seen one so close; usually they passed over at pressure-height, mere sparkles to the unaided eye.

Axwep and Drotninch returned to the lookout platform, and waited along with everybody else until full daylight also overspread the shore, revealing a stark, discolored mass of shriveled foliage.

"That's worse than what we were warned to expect," muttered Thilling as she stored away her exposed sheets. Awb was about to reply, when—

"Look!" somebody screamed.

On the top of the peak something was moving. No: the top of the peak itself was moving! It was cracking apart, it was shedding chunks of rock, it was tilting, it was sliding and rasping and collapsing and slamming down with horrible slowness in an inexorable paradigm of disaster. The guide-cables snapped, the passenger floater leapt up the air like a frightened pitchen taking off from a wave-top, the new plants on the mountainside vanished in a cloud of dust and boulders, so all at once that Awb could not take everything in.

The avalanche subsided into a monstrous scree, blocking a canal that led from the base of the mountain to the shore along which, presumably, rubble had been carried to create the sheltering mole now visible between the city and the land, the first stage in preparation for a full-scale harbor. All the seafarers stood transfixed with horror as the dawn breeze carried off the dust.

But from the shore, incurious and dull as mere animals, most of them sickly and with their mantles ulcerated, a few natives gazed at the city before dismissing it as incomprehensible and setting off to seek food in the shallows.

What Awb found most appalling, as he strove to hold his telescope steady, was that not a single one among them made for the scene of the catastrophe, to find out whether anybody lay in need of help.

II

"Of course we know what happened," said Lesh, so weary she could scarcely flex her mantle, let alone stand upright. "It's another of the unforeseen disasters that bid fair to wreck our project! Without our noticing, a pumptree shoot invaded a slanting crevice and expanded there, turning the crevice into a crack and the crack into a split. Finally it sprang a leak. Water by itself might not have made the rock slide, but mixed with nice greasy sap—smash! You can see the way it must have gone quite clearly from the air. But what we now have to find out is why. Pumptrees simply aren't supposed to act like that!"

She was the resident chief designer for the observatory project. She and a couple of assistants had been all dark on the mountain-top investigating reports of irregular pulsation in the pumptrees. About the time Voosla hove in sight they had concluded the trouble was due to nothing worse than irritation caused by the topsoil they were carrying in the form of slurry, which necessarily contained a trace of sand and gravel. The roots of the toughtrees which would eventually form a foundation for the large telescopes needed more nutriment than they could extract from bare rock, at least if they were to grow to usable size in less than a score of years. Besides, the intention was to keep the peak in more or less its original form, and toughtrees certainly did erode rock, given time.

Down below there was plenty of rich fertile dirt, and it had seemed like a brilliant shortcut to mix it with water and render it liquid enough for pumptrees to transport it upward. This was not entirely a new technique; something similar had been attempted recently in desert-reclamation.

So Lesh and her companions had remounted their floater, to take advantage of the coolness of the gas in its bladders before sunshine increased its buoyancy and obliged them to have it hauled down, and that lucky chance had spared their lives. In fact, as things had turned out, everybody was safely accounted for, except perhaps a few natives, and they were so stupid they could rarely be taught to answer their names. Still, the harm done was severe enough.

"It's set us back years!" Lesh mourned.

"Well, I did warn in my original report, when the site was first surveyed, that there must be something amiss in this area!" That was from Drotninch's elderly colleague Byra, hunching forward.

"You didn't lay much stress on the point, then," Drotninch countered. "As I recall, you concluded that 'the abnormalities found fall within a range of normal variation comparable to that in the Lugomannic Archipelago!' "

Other voices were instantly raised. Awb recognized Phrallet's—trust her to poke a claw in, he thought morosely—but none of the others. It was dark again now, and even though a few luminants had been brought from Voosla it was hard to make out anybody's features, here on the gritty beach beside the unfinished mole.

In any case, he was too worn out to care. So much had happened, he was half-convinced he had wandered into dreamness and would recover to be told he was suffering from fever and delirium. He wanted to have imagined what he had witnessed today, the stench of shock and misery exuded by the people working here as they surveyed the rain of years of effort. At his age he had scarcely begun to conceive ambitions, let alone put them into practice, and he had been stabbed to the pith on realizing how trivial an oversight could cause such a calamity. That vast mound of shattered rock blocking the canal; that dismal garland of carefully tended plants now dangling over the new precipice so high above; those tangled cables which only yesterday had guided massive loads up and down Fangsharp Peak...

Too many images, too much emotion. He let his mind wander and made no attempt to follow the discussion.

Then, unexpectedly, he heard Axwep's boom of authority, and reflex snatched his full attention, just as though they were in mid-ocean with a line-squall looming.

"Now that's enough of this wrangling!" the mayor rasped. "I thought we were bringing cool-minded scientists here! I'd like to see a bunch like you put in charge of a city when one of her incorporated junqs turns rogue and has to be shed because you can't kill her without attracting sharqs or feroqs! Fancy trying to keep your musculators working when rogue ichor's leaking through the circulation, hmm? If you can't cling to your drifting wits when you're not even in danger of your lives, it's a poor lookout for your project anyhow! So shut up, will you? And that goes for you as well, Phrallet! I don't care how much of the voyage you spent chatting up our guests while I was busy running Voosla—you can't possibly know enough about the problem to discuss it. Even Drotninch hasn't been here for two years, remember."

The direct insult provoked Phrallet to a reeking fury, and she rose to full height in a way that proved she had worked little, if at all, during the bright-time; none of the others present had pressure left to match her. For an instant she imagined she was at an advantage.

Then, suddenly, she realized that those nearest her were all landlivers, perfumed against such a naked show of emotion, and they were shuffling away from her in distaste. With a muttered curse she stormed back to the city, splashing loudly off the end of the mole.

And good riddance, Awb thought. He had long wished that something of the sort might happen. Of course, like everyone else, he would have hoped to love his budder ... but did she like him? Had she liked any of her offspring? True, it was a custom in every floating city to trade off young'uns to communities where, for some reason, the fertility treatment had not properly taken, or been counteracted in emergency, but she never stopped boasting about what splendid bargains she had struck for her four eldest ... all of whom were she'uns.

Awb's mantle clenched around him. So were three of Axwep's—and they were still in the city, one studying, two working on the secondary plants. The mayor didn't object to their presence. But Phrallet could all too easily have seen her buds as potential rivals, and that would explain so much, so much!

Oh, if only he had been budded to somebody like Thilling! But the picturist must be sterile; she had no bud-scars at all.

A faint idea hovered at the edge of his awareness, in that dim zone where memory, imagination and reason blurred together. He was far too tired to pursue it, though, and turned his mind back to the discussion. Axwep was presiding over it now, directing its course like a commander of old at the bragmeets recounted in ancient legend.

She was saying: "So when you first came here, and heard about peculiar plants and deformed animals, you found no actual evidence, correct?"

"The nearest reports," Byra confirmed, "were from several padlonglaqs away. The local vegetation displayed some unusual features, but that's often the way with modified Gveestian secondaries, isn't it?"

"What about the natives? I haven't seen much of them, but they strike me as very peculiar indeed!"

Axwep's thrust went home. Byra broke off in confusion. But Drotninch spoke up bluffly.

"It was regarded by the Council of the Jingfired as a great advantage that the folk hereabouts were unlikely to protest at our intrusion!"

There was a murmur of approval from the assembled scientists, growing restive at the mayor's intervention.

"I thought so too," Lesh said suddenly. "But now I don't. Oh, it's very well for you lot to argue in such terms, comfortable at home in Chisp! What do you think it's been like for us, though, surrounded by people we can't even talk to? It's been preying on my pith, I tell you straight, and I don't think I'm the only one."

Seizing her chance, Axwep said, "Can you relate the loss of your luminants to any particular event? Or the failure of your nervograps? After all, when you first arrived everything seemed normal except for the people. What did you do that might have—oh, I don't know!—imported a new infection from beyond the hills, say?"

There was a pause. Lesh said at last, with reluctance, "Well, I have wondered about..."

"Go on!"

"Well, we do require a lot of fresh water, you know, and we were running short the winter before last, because it freezes so hard around here, and one of our aerial surveys noted that a stream just the other side of the local watershed was still free of ice. So last spring we tapped it with some quick-growing cutinates, and by the end of the summer we had a good supply. It's lasted through the winter exactly as we planned. But in any case, what could that have to do with the sudden blight we've suffered? We're all trained personnel, and we have the most modern medical knowledge, and—"

"Nobody's told me," Axwep cut in, "but I'll wager that the local folk have long been accustomed to collecting food from beyond the watershed. Correct?"

"Ah ... Yes, I believe so."

"Because the vegetation there is lusher, or better to eat, or superior in some other way? Or don't you know?"

"I already told you: some of the Gveestian secondaries are unfamiliar, but we're on the edge of a climatic boundary, so I suppose the cold—"

"It's time to stop supposing and start thinking," murmured a soft voice at Awb's side, and Thilling settled close to him. "No need to explain what's going on. I can guess, even though it's taken me until now to get all my images developed. They practically tell the story by themselves ... Say, wasn't it Phrallet I sensed passing me on the way here? What's with her? She was reeking!"

Awb summed up the reason, and Thilling clacked her mandibles in sympathy.

"It's not going to be much fun for you on Voosla for the foreseeable future, is it?"

That was it. That was the hint he needed to complete the idea which had been so elusive before. Even though life at sea was preferable, life anywhere in company with so foul-tempered a budder...

"Do you spend most of your time on land?" Awb whispered.

"No more than I can help. I like to travel, I'm good at what I do and get plenty of commissions. Why?"

"Would you accept me as an apprentice?"

"Hmm! I don't know about that! But"—quickly before he let his mantle slump—"you can help me on shore until Phrallet gets over her present mood. Then we'll see. Fair?"

"I can't thank you enough!"

"Then please me by keeping quiet for a bit. Oh, if there were a bit more light...! But this sort of thing needs to be fixed in sound, really. You should be listening: all these recriminations about who betrayed Lesh and her chums by not exploring the far side of the watershed properly!"

Awb composed himself and did his best to concentrate. But all he could think of was how suddenly the blight must have struck if a mere two years before experienced investigators like Drotninch and Byra had found nothing in this area to worry them.

III

Finally a weak conclusion was reached. After the extent of the damage had been assessed, so a report could be sent back to Chisp, an expedition must cross the watershed and test the plants there for infective organisms, even though none had been found over here.

So much could have been agreed straightaway, in Awb's view, but everybody was so overwrought, making decisions seemed like excessively hard work. He was as affected as anyone else. He felt he ought to be doing something, if only getting better acquainted with the observatory site, but it was still dark, and what could he learn without adequate luminants? Voosla carried seed of a recently developed type that rooted immediately in a shellful of soil and could be carried around draped over a pole, lasting for up to half a score of darks, exactly the kind of thing that was called for in a crisis like this. But nobody had expected a crisis, so none of them had been planted in advance, and even if they were forced now it would be days before they ripened.

In the end he remained inert, pondering a mystery that had often troubled him before.

Why was it that, when the world was generally calm by dark, it was always harder to analyze and act on important memories? Surely the opposite should have been true! Yet it never was. While the sun was down, memories lurked on the edge of consciousness like dormant seeds, only to burst out when there was so much else going on that one would have expected them to be smothered. Oh, they were accessible enough at a time like now ... but they didn't seem to connect to activity.

Awb had been puzzled about this for a long time, for a reason he suspected people from fixed cities would not appreciate. Incomprehensibly, though, when he mentioned it to people on Voosla—Tyngwap the chief librarian, for example, who had custody of not only the city's history and navigation records, but also data concerning all the shores she had touched—they missed the point of his question too, brushing him aside with some casual reference to the light-level or the local air-pressure.

Which manifestly could have nothing to do with what he was trying to figure out!

Even though cities like Voosla were commanded by experienced weather-guessers, storms sometimes broke out unexpectedly across their course, perhaps precipitated by a meteor; nobody could forecast those, but the sparks they shed through the upper air did often seem to provoke foul weather. If such a thing happened in the dire middle of the dark, the people's response was as prompt and efficient as by day, and they were quite well able to put off their usual time for rest and reflection. But they never seemed to need to make it up later! Physical exhaustion due to lack of pressure was one thing; it demanded food and drink and that was enough. Mental exhaustion was something else; it gathered in the lower reaches of the mind, and eventually burst out in altered form. Take Phrallet as an example. What she had done this dark, by intervening in the scientists' debate without knowing the facts, was typical of her excessive need to be active, vocally or otherwise. It didn't render her unattractive to males, but her fellow she'uns didn't like her much, and as for the status accorded to mere males ever since it had been established that originally they had been parasitical on females and used them simply to bear their buds...!

Well, only the fact that inbreeding rapidly led to deformity had prevented cities like Voosla, and probably fixed cities as well, from reducing males to simple tokens, like certain lower animals whose symbiosis must go back so far in the history of evolution that even the finest modern techniques could not recover a single independently viable male cell. Luckily—from Awb's point of view—it had early been shown, in the light of Gveest's pioneering work (and he was male and some said had betrayed his kind!), that species lacking the constant chemical renewal due to symbiosis were precisely those most vulnerable to climatic change. Where were the snowbelongs of yesterday, hunted to extinction as soon as the Great Thaw overtook them? Where were the canifangs, pride of the earliest bioscientists—not that they called themselves by any such name in that far past? They had been deliberately made to specialize, and they died out. The list was long: northfinders, hoverers, fosq, dirq, some exploited by folk for their own ends, some simply unable to compete when their range was invaded by a more vigorous rival or even a rash of Gveest's new plants!

Beyond them, too, according to the latest accounts, there had been ancestral creatures without names, which pastudiers labeled using Ancient Forbish, receding to the very dawn of time.

Did they think? Did they reason? Certainly they left no message for the future, which was a mark of the folk; as long ago as the age of legendary Jing, means had been found to warn posterity about the menace looming in the sky. Without such aids, probably the Age of Multiplication would have proved a disaster—

No, not necessarily, Awb corrected himself. Eventually the truth could have been rediscovered. But perhaps there would have been less reason to go in search of it, and by the time it was once more chanced on it might have been too late: the sun might be being drawn inexorably into some new star, up there in the Major Cluster ... He tipped his eye in search of it, and was astonished to realize that it was nowhere to be seen; the sky was blue, and everybody was dispersing to daylight duties.

What was Thilling apt to think of him if he stayed here mooning? Hastily he scrambled to his pads and set out after her. It was a vast effort to catch up, since his pressure yesterday had been so badly lowered, but he struggled on, reminding himself that all effort was made the more worthwhile by knowing how the ancestors had dedicated their lives to the survival of descendants they could never meet.

The first part of the bright was spent in making a careful record of the damage caused by the landslide, and Awb followed Thilling from place to place carrying bulky light-tight packs of the sensitized sheets she still referred to as "leaves" in memory of a more primitive technology. For the first time he gained a proper impression of the complexity of the work that had gone into creating the site for the observatory. Planning it must have been even harder than, say, founding a new fixed city, what with digging the canal to carry broken rock and make the mole, stringing the floater-cables, supplying food and accommodation for the workers, all of whom had had to be recruited at a distance and were used to a high standard of living. Several times he heard it vainly wished that the natives could have been enlisted, but today, again, they went about their own animal business, apparently incapable even of wondering about this intrusion into their placid world. If any of them had indeed been killed by the landslide, they showed no signs of grief.

Moreover there were mounts and draftimals to provide for, the musculators and cutinates, the floaters themselves constantly in need of the right nourishment to replenish the light gas in their bladders ... Awb knew perfectly well that when they first joined Voosla the people from Chisp had occasionally had difficulty finding their way around on her numerous levels, but he couldn't help feeling that, if they were accustomed to places like this, they ought to have found so small a city comparatively simple.

When the sun was at its highest—not very high in these latitudes, of course—Lesh gathered her companions on the top of the scree caused by the landslide, and started working out how long it might take to clear away. Already draftimals were dragging musculators towards it, along with grabbers and scoopers.

This spot afforded a splendid prospect of the area including the bay where Voosla was lying, minus her giqs, all of which had been detached and were now spread as far as the horizon. Delighted, Thilling used up her stock of sheets in fixing a view in each direction, returned them to their pack, and asked Awb to take them back to the city and bring replacements. Nervously, because he had no wish to encounter Phrallet, but equally none to disappoint Thilling, he complied.

It took him a long time to regain the shore because the usual branchways were decaying, like so much of the vegetation on this blighted coast, and he had to stay on the ground most of the way. The stink of rotting foliage was all-pervasive, and he wondered how the people working here could bear it.

Coming in sight of the sea again, he discovered that a strange briq had entered the bay. She must have been just around the western headland when he looked before, because she was of a type by no means speedy, the broad northern breed called variously smaq or luqqra much in favor for carrying bulky freight. Voosla had crossed a number of them during the couple of brights prior to landfall.

As she touched the side of the city, Axwep came to greet her commander, and by the tune Awb arrived they were deep in conversation.

"There's somebody who can probably tell us," the mayor said, interrupting herself. "Awb! Do you know where Lesh is?"

"When I left, she was on top of the rockpile trying to work out how long it will take to clear," Awb called back.

"Will you be going back there?"

"Yes, I'm on an errand for Thilling."

"Then you can carry a message. Come here. This is Eupril; she's from the quarry down-coast which we passed the dark before last."

Awb remembered that being pointed out to him, at a spot where luminants grew normally. He had never seen a quarry, but he knew about such places where specially developed microorganisms were used to break up rock and concentrate valuable elements to enrich poor soil, or even to extract metals. In ancient times, it was said, the folk had employed fire for similar purposes: however, during the Age of Multiplication fire had fallen out of use except for very special purposes, because most burnable substances were far too valuable for other applications. Most people nowadays were terrified of it. Sometimes, far out at sea, one could smell smoke on the wind, and the Vooslans would mutter sympathy for the poor landlivers whose homes and crops were going up in flames.

"I don't suppose it'll do much good," Eupril said sardonically. She was thickset, with the forceful voice of one used to calling over long distances, rather like Axwep. "I've warned and warned those people that they picked a bad site for this observatory of theirs. We surveyed it when we first came up here, and though there were a lot of useful minerals we decided against prospecting further. We didn't like the look of the natives, nor what we found the other side of the ridge. People who won't listen make my pith ache, you know? Of course, when we saw a chunk had fallen off the mountain, we thought we'd better come and see if they needed help. We have no other way of finding out. Used to have a nervograp link, but it went bad on us."

"From the same blight that's spoiling everything else?" Awb suggested.

"Now that's the other reason I'm here," Eupril said. "We have news for Lesh. It's not a blight. It's a poison."

"How can you be sure?" Axwep demanded. "I mean, I know the people here haven't been able to isolate a causative organism yet, but there's a lot of talk about germs you can't see even with the best microscope, that go through the finest filters and can still do damage—"

"We're sure," Eupril cut in. "Who'd know better than a concentration specialist? Matter of fact, we've been worrying about something of the sort ever since they warned us they were going to tap water from beyond the ridge and discharge it here, because there's a current that follows the coast and washes right down to our place. Still, they claimed it was only going to be for a year or two, and a bit of extra fresh water might conceivably have been an advantage, because we use a lot of cutinates and even with our best salt-precipitators they tend to wear out pretty quickly. So we didn't raise as much objection as we should have, what with the delay involved in sending a delegation to Chisp and the rigid attitude of the Jingfired. Everybody knows they think they're incapable of making a mistake, hm? Bunch of arrogant knowalls, that lot!"

She shrugged with her entire mantle. "Anyway, nothing much happened last year, so we more or less stopped worrying. This season, though, our concentration-cultures have started to die off, and our cutinates are developing blisters like we never saw before, and just the other day we finally traced the problem. Of course we thought it was disease at first. It's not. It's definitely a poison that's coming to us in solution, in the water, and even diluted as it is when it reaches the quarry it's deadly dangerous. We don't have anything that can resist it. Our toughest precipitators turn black and rot within a month."

Stunned, Awb said, "Mayor, I think this is something Lesh ought to hear personally. I mean, I couldn't possibly repeat such an important message and be sure of getting all the details right."

"That's not the message," said Axwep with gentle irony. "The message I meant was simply a request to get here as quickly as she can. I'm sure you can manage to relay that much!"

"Probably not," said a harsh voice, and Phrallet appeared, swarming along the nearest slanting branchway. "Even if he is of my own budding, I wouldn't trust him to find his way from one side of Voosla to the other!"

Furious, Awb reared back, holding up the pack of image-sheets like a shield. "Thilling trusts me!" he blurted. "She sent me to bring a fresh batch of these for her!"

"Instead of which you're standing about gossiping?"

"But—!"

It was no good. All his life he had found it impossible to get his budder to take him seriously. Clamping his mandibles tight shut, he muttered an apology to Axwep, who seemed mildly amused—a reaction calculated to irritate Phrallet still further—and hastened in the direction of Thilling's bower.

IV

The first thing Axwep asked Lesh when the latter returned to Voosla— annoyed at the interruption even though Awb had done his utmost to explain its reason—was whether water was still being drawn from beyond the ridge; if so, the city should be moved.

"All our cutinates got crushed by the rockfall," was her curt reply. "They're not pumping anything right now, and in fact I'm not sure they'll survive. Now what's all this about, Eupril?"

The concentration expert sighed. "Oh, I know you suspect our people of wanting to drive you away because we have designs on this site for our own purposes, but that's untrue and unfair! I came with proof of the danger you're in. Carry on like you're doing, and those toughtrees you're planting on the peak will turn as rotten as everything else. Then what will become of your telescopes?"

"Proof? Let's see it!" Lesh snapped.

"I'd rather present the evidence in proper order. You're supposed to have a ripe bunch of experts here now, or so Axwep tells me. Maybe some of them will be a bit less—ah—emotionally committed. Let them be the judges."

For a second it seemed that Lesh was going to yield to rage; then, resignedly, she slumped to four-fifths height.

"Very well, I'll send for Drotninch and the rest. But where are we going to get the water we need if we can't take it from across the ridge?" With sudden optimism: "Maybe from the sea! You can let us have some of your salt-precipitators!"

"They're dead or dying," Eupril answered. "We've had to order fresh stock, and it'll be months before we have any to spare."

Thilling, never one to miss important news, had accompanied Lesh back to the city, and stood beside Awb listening keenly. Now, however, she muttered, "This could go on for ages. Come with me. You said you'd like to be my apprentice, so let's see if you can learn to trim a lens while I develop the images I've caught so far."

Excited, he followed her down into the very core of the city, where the junqs fretted and throbbed, dreamlost perhaps in visions of their ancestral freedom. Here a small dark bower had been assigned to the picturist, which she could make entirely light-tight. Judging by the stink of juices and concentrates which blew from it when she finished work, it must be very unpleasant in there. Awb began to have second thoughts. But he willingly accepted the blade she gave him, and paid total attention when she demonstrated how to cut loose the full-grown lenses that bulged from the plants she had hung to nearby branches.

"Here are the measurements for a mid-range lens," she said. "Try this kind first. If you spoil one I shan't mind. If you spoil two, I'll be disappointed. If three—well, I'll probably part you torso from mantle! Understood?"

Awb signed yes.

"Get on with it, then. Go back where there's better light. And take your time. I may not be through with this lot before sundown."

And indeed the sun was touching the horizon when she rejoined him. He had completed two of the lenses, and the second was flawless as near as he could tell, but he waited on her verdict nervously.

"Hmm! Very good!" she pronounced, surprised and pleased. "More than I can say about the one I have on the fixer at the moment. I mean, look at these, will you?"

She flourished a selection of the sheets she had exposed in the morning. Awb examined them. To his untutored eye they appeared satisfactory, and he said so.

"No, look again! Here, here, here!"—each time with a jab of her claw. "There's a blur, there's a smear, there's a streak ... At first I thought the fixer must be leaking light, but I've checked and doublechecked. I suppose there must be a blister in the lens, but I can't locate it."

Awb ventured, "But then wouldn't the blurs always reappear in the same place? And these don't."

Taken aback, she said, "Give those back to me ... Hmm! I wonder if it could have to do with the angle of incidence of the light—No, that wouldn't fit either. And most of the early ones, come to think of it, are all right. It's only from about the point where we climbed up the rockfall that I started having trouble. Maybe a wind-blown drop on the lens, but I was careful to shield it ... Oh, I can't figure it out, unless..." She fixed him with a stern glare. "You didn't drop the leaf-pack by any chance?"

"No, I promise I didn't!" Awb cried, recoiling in alarm. "And if I had, surely the damage would show on one edge or one corner?"

"Ah ... Yes, of course it would. I'm sorry." Thilling clattered her mandibles in confusion. "This makes no sense at all, you know. It's as though some trace of light—very bright light—got through the pack-wrap, and..."

"A fault in the making," Awb offered.

"I suppose so." All of a sudden she sounded weary. "But I never had trouble with my supplier before. I've been trying not to arrive at that conclusion, because if all the leaf-packs I have with me are faulty, I might as well not have come."

Startled to find himself in the unprecedented situation of having to reassure an adult, Awb said, "Please, you're making too much of this. As far as I could tell, those images were fine until you pointed out the flaws. Nobody is likely to notice what worries you so much, except maybe another picturist."

"I suppose you're right," Thilling sighed. "Let's go and eat something. I've had enough for one bright, or even two."

Because the scientists were still arguing, Axwep had suggested that Lesh and her senior colleagues, along with Eupril and some of her companions, should eat this evening on Voosla, where the food was better than on shore. However, although she made it clear that she could not repeat the invitation regularly, because any floating city was in a delicate balance with its inhabitants and the best efforts of the giqs could never gather as much nourishment as she collected for herself in open water, there were some who instantly accused the mayor of wasting public resources. Wasn't it bad enough to have brought these scores of passengers all this way?—that was their cry, and they took no account of the fact that Voosla had been specially replanted with new high-yielding secondary growths developed at the University of Chisp, which would continue paying her back long after the return voyage.

Prominent among those who complained, of course, was Phrallet. Axwep had finally lost patience with her, and ordered that she be forbidden access to the prime food zone. Tagging along behind Thilling, Awb managed to steal in and join the company, hoping desperately as he nibbled a bit here and a bit there that his budder would not get to hear.

Finding herself next to one of Eupril's fellow quarry-workers, whom she had seen earlier but not spoken with, Thilling said, "What's all this about a poison, then? Why can't it be a disease? Name of Thilling, by the way."

"Name of Hy," said the other. "Well, it's because of the way it acts in living tissue, of course. Ever hear of a disease organism that simply killed the cells around it, without spreading, or reseeding itself at a distant site? Oh, we've carried out all the tests we're equipped for, and we even managed to get our claws on the corpses of some of the natives. They don't seem to care about their dead, just leave 'em to rot. And in every single case we've found necrotic tissue, either in the digestive tract or quite often in the nerve-pith, and if you take the dead center—excuse me!—and triturate it and apply microscopic drops to a suitable test medium, like the partly flayed rind of a cutinate ... Well, what would you expect to see?"

Thilling frowned with her entire mantle "A whole series of infection-sites, obviously."

"That's exactly what we thought. Wrong. One and only ever one new patch of necrosis. The rest is unaffected."

Chomping solemnly, Thilling pondered that awhile. At last she heaved a sigh.

"It doesn't sound any more like a poison than a disease, in that case, does it? Still, it's not my specialty, so I have to take your word. But I always thought poisons worked by spreading throughout the system."

Awb was glad to hear her say that; it meant his own main question was likely to be answered.

"So they do, for the most part. I've been dealing with poisons much of my life, because you never know, when you feed new ore to a concentration-culture, whether it's going to survive on it. But I never saw the like before: a poison so lethal that a particle too small to see with a microscope can kill cells over and over. It doesn't dissolve, it doesn't disperse, it just sits there and kills cells!"

"Thilling!"

They all turned, to find Drotninch approaching.

"You are coming with us to check out this hot stream tomorrow, aren't you? Yes? Good! We're going to leave at first bright. Lesh is working out how many mounts can be spared. Will you need a whole one for your equipment?"

With a wry twist of her mantle Thilling answered, "Not a whole one. I have a volunteer helper now."

V

Slowly the expedition wound its way up the narrow trail cut to facilitate laying of the cutinate pipeline. It had remained alarmingly clear of overgrowth, though Lesh said it had not been recut this spring. It was as though the surrounding plants, both Gveestian and natural, had bowed away from it.

The air was comfortably calm, and since the morning of the city's arrival there had been scarcely a cloud in the sky, let alone the threat of a storm. Nonetheless Thilling's weather-sense was reacting queasily. She did her best to convince herself it was because of her unpremeditated decision to accept Awb as an apprentice. Taking on someone from so utterly different a background, and with such an awful budder to hint at how he might turn out in the long term ... Had it been wise?

Just to complicate matters, Phrallet was a member of the party. Whether out of misplaced ambition, because she fancied she might make a better impression on this trip than usually at home on Voosla, or out of jealousy of Awb, or simply out of bad temper because of what Axwep had said to her last dark, she had insisted on coming along. Drotninch, who had gotten to know her slightly during the voyage, was no more in favor than was Thilling; however, Axwep was glad of the chance to be rid of her for a while, and she possessed sufficient charm as regarded strangers for Lesh to say with a shrug, "Why not? We can always do with an extra set of claws, and a volunteer is better than a draftee."

Thilling's view was that she was apt to be more of a nuisance than a help. And she was equally dubious about Awb. She still could not quite rid herself of the suspicion that her images might have been spoiled by his carelessness. Moreover she was moderately certain that his ambition to spend his future in light-tight bowers reeking of chemicals was due less to a genuine interest in the work than to the fact that if he became Voosla's first official picturist he would always have an excuse to shut himself away from his budder.

Still, there was little point in speculating. Determinedly she forced her attention back to the country they were traversing, only to find that the view made her more worried than ever.

From the canal which carried waste and usable rock to the new harbor, irrigation ditches had been ichored off for the crops that fed the workforce. So much was normal; so much was sensible economy.

Yet the point in time at which the crops began to fail coincided with the failure of the nervograp links to the outside world, and in turn followed the first use of water from beyond the watershed. How was it that supposedly rational people could have overlooked the connection? They definitely had! Even in the light of what Eupril and Hy reported, Lesh was still obstinately hoping to find that the water-supply had nothing to do with the—the blight, the poison, whatever it might ultimately prove to be.

Now, fixing images of the true extent of the devastation in the morning shadow of Fangsharp Peak, Thilling started to wonder whether those who had been living here for two or three years might not already be affected, already be on the way to matching the miserable mindless natives.

Then she noticed something else even more alarming as the mounts wound in single file up and over the ridge. During the first part of the bright, the beasts had too much sense to browse off the nearby foliage, sere and discolored as it was. About noon, however, when presumably they were starting to thirst, the one carrying among other loads her own equipment did begin to help itself now and again from the nearest branches. But the leaves were wilting, and the rind of the cutinates whose line they were following was patched with suppurating black.

She glanced at Awb, laboring along behind her under the burden of her spare image-fixer and a spare lens-plant, and realized that he too appeared uneasy. But neither Lesh nor Drotninch seemed concerned. Why not?

Well, perhaps she was worrying overmuch. She strove to make herself believe so.

Night fell late in these latitudes, and was short. They crossed the watershed before they lacked enough light to wait for tomorrow's dawn. The chance to rest was welcome; they all needed to accumulate pressure for the next stage of the journey. But Thilling was dismayed anew when she realized that Lesh, who had been responsible for organizing the expedition, expected everybody, and the mounts too, to subsist off the local plants because, as she said, "it would only be for a day or two." This was enough to startle even Drotninch and Byra, and a furious argument broke out in which—predictably—Phrallet was prominent.

True, there were plenty of edible secondary growths of the kind which that far-sighted genius Gveest had modified to provide for the folk during their traumatic population explosion. Possibly, as Lesh was now claiming, the planners of the observatory project had seeded them deliberately to furnish an emergency resource for the workers. More likely they had arrived of their own accord; their spawn was designed to drift on the wind and displace natural rivals when it settled. But those which grew close to the path were so unwholesome both in appearance and in odor...

Even though she had no luminants, and as yet only a shred of moon was visible, very close to the horizon, Thilling slipped away to a spot where a few cautious bites convinced her the food was safe, or at least safer. Glancing up on hearing a noise nearby, she was amazed to discover that Awb was here already. Good for him!

But he was tensing as though afraid of being reprimanded, and small wonder, for that was certainly how Phrallet would have reacted. Suddenly full of sympathy for this young'un, Thilling said sharply, "All right, keep your pith from boiling! What made you come this way?"

"I just didn't like the smell of what the mounts were eating," he muttered.

"Nor do I. I think that worn-out old nag they assigned to us is going to rot in her pad-marks before we get where we're going ... By the way!"

"Yes?"

"I'm sorry I accused you of dropping my leaf-packs. I've been watching you all this bright, and I'm satisfied that you've been taking great care of my gear. I'm also convinced that there's something in what Eupril says about poison. When you're through eating, come and set up my dark-bower. I expect all today's images to be faulty."

"Do you want them, then?" Awb countered in confusion.

"What I mostly want is to do Drotninch and Byra in the eye because I have an eye that they don't. If I'd been here with the original expedition that chose the observatory site—! But never mind that. I sense something's bothering you. Out with it!"

"Are you really going to spend all dark developing your—uh— leaves?"

"And why not?"

"Well, I'd have thought..." Awb shifted uncomfortably from pad to pad. "You know—review today into memory, build up pressure for tomorrow..." He subsided, more at a loss than ever.

"Oh, there's plenty of time for that while you're waiting for images to develop—"

It was her turn to break off, gazing at him with astonishment in the faint starshine. "Are you trying to tell me you've never been educated in dark-use?"

"I don't know what you mean!"

"Oh, dear!" Seizing a clump of funqi, she settled beside him. "It's no news to me that cities like Voosla are behind the times, but this is incredible."

"Sorry to appear so ignorant," Awb muttered resentfully.

"Oh, I don't mean to be matronizing, I promise. But ... Look, young'un, I just took it for granted that you must have your own version of dark-use training. I mean, I know the People of the Sea are contemptuous of landlivers who can't move to avoid bad weather or follow the best seasons, and the rest of it, and what's more I know they can turn to in mid-dark and cope with gales and storms, so ... Well, surely we have to exploit all the time at our disposal if we're to meet the challenge of the future, right? You know what I mean by that, at least?"

"Of course!"

"That's a mercy ... Oh, I'm starting to sound like Phrallet, and I'm ashamed. She's anti-male, by the rude way she treats you, and I'm not. I admit I'm sterile, and the fertility treatment won't take in me, but that's neither here nor there. Just makes me wonder about those it took in much too well! But I sense you have a whole branchful of questions, so I'll see if I can answer them without being told what they are."

She filled her mantle for a long speech; he heard the hiss.

"Why shan't I mind if my images are faulty? Because I think the faults may teach us something we never knew before. Why am I appalled that you haven't been trained in proper dark-use? Because I don't hail from where you think I do. You believe I'm from Chisp, don't you?"

"I—ah—I did assume..."

"Eat your assumptions, then. I was budded in the Lugomannic Archipelago."

"Where Gveest discovered the cure for infertility?" Awb burst out, and was instantly horrified at himself, because she had just mentioned her own sterility. But her only reaction was mild amusement.

"More to the point: where someone you never heard of, called Pletrow, realized after she'd finally had the bud of her own which she longed for that in order to cope with the consequences of Gveest's success there had to be a means of exploiting dark-time, instead of squandering it."

Exuding fascination, Awb hunched forward. "I've always resented that myself! I mean, one never really stops thinking, does one? It's just that by dark it always seems so much harder to make action match intention!"

He added self-excusingly, "I envy you the fact that you're going to spend this dark doing something constructive, you see. I don't know how."

For a long while Thilling remained indecisive. Should she broach her most precious secret to this chance-met stranger? Yet the magnitude of the catastrophe that was set fair to overwhelm the great observatory was daunting, and the need for the information it could supply was so urgent. Could she confront the insights she was burdened with entirely alone?

No: she could not. She needed to confide in someone, and none of the scientists from Chisp was right to share her private anxiety. At least Awb had fought back against the handicap of being Phrallet's bud...

She said after a small eternity, "Then I must teach you how to liberate consciousness from concern with digestion. That's the first of the mental exercises Pletrow developed for the Jingfired."

"You mean you…?" Awb's pressure failed him.

"Yes, I do mean!" Already she was half regretting her admission. "But if you so much as hint that you're aware of the fact, I'm bound by oath to leak you. Understood?"

Fervently he echoed, "Understood!"

"Very well, then. Now there's one other thing I ought to ask you. But I'm not going to. If you're the person I think and hope you are, you'll work it out yourself."

"Does it have to do with why Lesh doesn't want to consider any other site for the observatory?"

"Very indirectly I suppose it does. We all hope to bequeath some achievement to the future ... No, that's not what I want you to say. Think it over. In the meantime, what about setting up my dark-bower for me?"

VI

Was Thilling truly one of the legendary Jingfired?

That question haunted Awb as the party wended its way down from the crest of the ridge, still following the line chosen for the cutinates, either side of which the trees were stunted and their secondary growths pale and sickly. The stink of decay in the air was worse than where they had started from because it was older, as though even storms could not disperse it. Its impact was unnerving; one heard fewer voices raised to normal pitch, more murmurs of apprehension and more cries from unseen creatures in the overgrowth.

Along the bottom of the valley, where they were bound, ran a watercourse formed by the confluence of three streams half a day's journey to the east. It was the middle one which remained so warm during the worst of winter that it could keep the whole river free of ice. Nobody had explored it to the source, but presumably it must rise where there was hot rock of the sort well known on other continents, that created geysers or pools of bubbling-hot mud.

An earth dam had been built to make an artificial lake for the cutinates to draw from. Now and then they could glimpse the sunlight gleaming on its surface, wherever the vegetation had died back sufficiently.

That was disturbingly often.

Byra announced loudly, "This is far worse than what I recall from my first visit! If things had been this bad then I'd have argued strongly against choosing this site."

"I thought the Jingfired didn't make mistakes like that," was Lesh's snappish response. Close enough behind to overhear the exchange, Awb whispered to Thilling:

"Is she one of—?"

"Of course not!"—with contempt. "She's enjoyed giving herself the sort of airs she thinks might suit one of us ever since the first time she was assigned to a foreign survey team. She carries it off well enough to mislead the ignorant, but she's never dared to make the claim outright.

One of the reasons I was sent here was to make sure about that. It's all right, though: it's a bit of harmless vanity, no more."

"What do you think about Eupril's attitude towards the Jingflred?" Awb risked.

Thilling gave a soft chuckle. "The more people who feel that way about us, the better we can achieve our aim."

Confused, Awb said, "But I always thought—"

She cut short his words. "The real Jingfired, young'un, are never who you think they are. You have to know."

And she hurried up a convenient branch to fix another image from the treetops.

Awb found himself wishing they didn't have to rely on mounts, for it would have been quicker and more pleasurable to swarm along branchways in the ancient fashion instead of padding along on the ground. Away from the water's edge, and away from these discolored cutinates, the overgrowth mostly smelled normal despite its peculiar tint, so—

His thoughts came to a squeaking halt.

Why weren't there any people in this valley?

Where else on the entire globe was there such lush terrain without a city, a town, even a hamlet?

This is what the world must have looked like before the Age of Multiplication.

The thought struck him so forcibly that he uttered it aloud. Some of those within hearing responded as though he had chanced on a profound truth.

But not all. Phrallet was close beside Byra; she had moved in to offer comfort after Lesh made mock of her. Now she turned and said loudly, "Ah, that's my youngest bud making noises again! I wish I'd had another she'un that I could have traded off to benefit Voosla, but who wants a he'un, particularly a useless lazy one like Awb?"

Clack: Awb's mandibles rattled as he rose in fury to maximum height, heedless of Thilling's gear which he was carrying. There was no case on record of a budling fighting his budder, but after that—I

Except, amazingly—

(As the pheromones mingled in the taut still air with what the rotting plants exuded, but far fiercer ...)

Clackonclackonclackonclack: and abruptly climaxing—

"SHUT UP!"

It was Drotninch, fuming with chemical proof of the reason why she had been chosen to lead the university team.

"I don't want to hear any more arguments until we get to the lake and have something solid to argue about! In the meantime, save your pressure for moving your pads!"

Phrallet slanted her mantle as though to puff a blast of combat-stink directly at Drotninch, but Lesh, Thilling and even Byra signaled a warning of the consequences. She subsided, still angry, and let the rest of the party go by, falling in right at the end. As Awb sidled past, she glowered with her whole mantle, but said nothing.

He was indescribably relieved.

The sun was just at the zenith when they emerged on a flat bare outcrop of rock overlooking the artificial lake. The water-level was a little below maximum, as could be judged from the mud along the banks, some of which was a curious yellow color. There were automatic spillways to cope with the rise due to a spring thaw: a dense mat of small but coarse-stemmed plants along the top of the dam, designed to float upward and lift their root-masses just enough for the surplus to spill over without letting the dam erode.

At least, there should have been. In fact, the plants were decaying like everything else in the vicinity, and the mud along the banks was actually bare, whereas ordinarily it would have been fledged with shoots sprung from the riverside vegetation.

"Have you noticed," Byra said after a pause, "that you can tell at a glance which of the trees have taproots long enough to reach the river? They're dying off. Look!"

In a dull voice Lesh said, "So they must be sucking up the poison, if that's what it actually is."

"And the state of these cutinates!" Byra went on as she clambered over the edge of the rock and gingerly descended to the waterside. She prodded the nearest, and its rind yielded, soft as rotting funqus. A swarm of startled wingets took to the air, shrilling their complaint at being disturbed. Awb, with the quick reflexes of youth, snatched one as it shot past, and bent his eye to examine it.

"How long since you sent anyone to check out the cutinates?" Drotninch demanded of Lesh.

"As soon as the snow melted," was the muttered reply. "I was assured that everything was in order. At any rate the spillways were working properly, and above the water-level the cutinates looked pretty much all right."

"You didn't haul their ends to the surface and—?" The scholar broke off. "No, I don't imagine you'd have seen the need if they were still pumping normally. Were they?"

"Oh, they've been functioning fine. Though, now that I've seen the state they're in, I'm surprised they haven't burst at a score of places."

"So am I ... Well, before we disturb anything else we'd better fix some images. Thilling!"

"Just a moment," the picturist called back. "Awb, can I take a look at that winget?"

He surrendered it gladly. "Do you know if it's a regular local species?" he demanded. "I don't recognize it, but then I've never been so far north before."

"I have, and it's not," Thilling answered grimly. "It's deformed. Its body has tried to—well—double, hasn't it? Byra, I think you should see this right away!"

As she hastened toward the biologist, Phrallet drew close to Awb.

"Do anything to get yourself well in with the folk from Chisp, won't you? Eat any sort of dirt they throw at you! I did my best to be friendly, but I'm leaked if I'm going to bother anymore. I never met such a rude, bossy bunch."

Surprised at his own audacity, Awb said, "Maybe they just reflect your own attitude back at you."

"Why, you—!" Phrallet swelled with renewed anger.

"Awb!" The shout was from Thilling. "Bring those leaves we developed last night, will you?"

"Coming!" Awb responded, mightily flattered.

And Phrallet, luckily, did not dare to follow, but remained seething by herself.

Taking the image-pack, Thilling said, "I was just explaining that I don't expect any images I fix here to be of the usual quality. You haven't seen these yet, nor has anyone else, but ... Well, look at this one, for example, which was taken right next to the cutinates where there was a leak most probably caused when the top fell off Fangsharp Peak. Notice all those blurs and streaks?"

"It's as though the poison can attack your image-fixer too!" Awb exclaimed.

Passing the picture around, Thilling said dryly, "I shan't argue. I reached the same conclusion. I shall of course try fixing more images here, but like I said I don't expect them to be much good."

"But how—?" Drotninch began, and interrupted herself. "Now I'm going against my own orders, aren't I? We'll wait until we have something to discuss. Lesh, if you'd..."

Briskly she issued orders to each of the party, pointedly ignoring Phrallet until, conquering her annoyance, the latter advanced to ask if she could help too. She was sent to fetch samples of the dead plants from the top of the dam, while Byra set up a microscope to examine them with, and Awb followed Thilling to the best points of vantage for general images, before descending to the lake for close-ups of the bare mud and ruined cutinates.

Very shortly after there was a cry from Phrallet, in her usual bad-tempered tone.

"That was a foul trick to play on me! You did it deliberately, didn't you?"

The others stared in astonishment as she fled back from the dam without the samples she had been asked to collect.

"What in the world is wrong?" Drotninch demanded.

"It's hot! The top of the dam is hot! Oh, my poor pads! And the water isn't just warm, it's steaming! Look!"

"Why, so it is! But I promise I hadn't noticed. By dark I would have, but—Well, you didn't notice either, did you?"

The pressure taken out of her by that awkward fact, Phrallet subsided, grumbling. Regretting his earlier rudeness, for she was bound to seek revenge for it eventually, Awb muttered a word of apology to Thilling and himself hurried to the side of the dam. Cautiously he lowered to minimum height and began to probe the area, reporting in a loud voice.

"There must be water seeping around the end of the dam here—the subsoil is marshy. But it's definitely warm, and I don't understand why. All the roots are dead but they're still meshed together. And the top of the dam..."

He moved on, half a padlong at a time. "Yes, it's very warm, and very hard, too. Completely dried out, almost as hard as rock." He rapped it with one claw. "And there's this funny yellow mud; it's building up in layers. And—Ow! That is hot!" He recoiled in surprise.

"I think you'd better come away," Thilling shouted, and he was just about to comply when there was an unexpected commotion.

The mount that carried Thilling's equipment, which she had dismissed as an old nag, uttered a noise between a grunt and a scream, lost all her pressure, and measured her length on the ground.

VII

That nightfall none of the party had much maw for food. Byra had carried out a cursory examination of the dead mount, and what her microscope revealed exactly matched the description Eupril had given of the way the poison affected cutinates and precipitators at the quarry. The certainty that at least some of it must be at work in their own bodies took away all appetite.

While Thilling occupied herself developing the day's images, not calling on Awb for help, the rest of them lay up on the branches of the nearest healthy trees, as though being clear of the ground could offer them security in the dark, like their remotest ancestors. Of course, if any of the local animals had been as altered as that mutated winget ... But the Freeze, the Thaw, and the greed of the half-starved folk who had exploded across the world during the Age of Multiplication had combined to exterminate almost all large predators, and turned avoidance of animal food among the folk themselves from a moral choice into a necessity. Even fish nowadays was in short supply, more valuable to nourish cities than their citizens.

Awb thought of having to ingest the flesh of the mount whose stench drifted up to him, and shuddered.

As though the trembling of the branch he clung to had been a signal, Byra said suddenly, "What I don't understand is how there can be burns without fire."

"I thought you Jingfired knew all about everything," came the sour riposte from Phrallet.

"I never said I was Jingfired!" Byra snapped. "If I was, do you think I'd be here? They have too much sense!"

In the startled pause that followed, Awb found time to wonder why she had chosen this of all moments to disclaim the pose she had—according to Thilling—long adopted, and also whether Thilling herself...

But there was no time to ponder such matters. Perceptibly desperate to avoid moving the observatory to another site, Lesh was saying, "We've got to isolate this stuff! Once we know precisely what it is—"

"Isolate it?" countered Drotninch. "When it can kill any concentration-culture it comes up against? You heard what Eupril said, and the folk at the quarry have only been dealing with a trace of it, diluted over and over."

"Well, there are filters, aren't there?"

"Filters will trap everything above a certain size. In fact I'm beginning to wonder whether that may account for the dam being so hot."

"Next you show us how to light a fire underwater," muttered Phrallet.

"Any moment now," Byra promised, "I'm going to—"

"Byra!" Drotninch said warningly. But it was too dark and their pressure was too low for combat-stink; the keener note of simple fear predominated, and was compelling them gradually towards cooperation, much as it must have bonded their ancestors into forming tribes and eventually communities.

Awb shuddered again, but this time with awe and not disgust. It was amazing to be participating in so ancient an experience. Of course, something similar happened now and then at sea, when a storm assailed the city, but then wind and spray carried off the pheromones, and the decision to work together was dictated by reason.

How much was left of the primitive in modern folk? He must ask Thilling. If she were truly one of the Jingfired, she would certainly be able to answer such a question.

But the argument was continuing. Sullenly, as though not convinced that the others wanted to hear, Byra was saying, "It was the heat of the water that made me start thinking along these lines. Now I've realized what the tissue-damage in that poor mount reminded me of. I've got a scar where some young fool shone a burning-glass on my mantle when I was a budling. Instead of just comforting me, my budder made me turn even that silly trick to account. She dissected out a tiny scrap of tissue and showed me the way the heat had ruptured the cells. I noticed just the same effect in the mount. Of course, the damage is deep inside, instead of just on the surface."

"But so are the blemishes on Thilling's leaves!" Awb burst out. "They happen right inside a light-tight pack, or inside the fixer!"

Once again there was a pause during which he had time to feel dismayed by his own boldness. Byra ended it by saying, "Phrallet, I can't for the life of me understand why you think your budling is unworthy of you. I'd be proud if one of my young'uns had come up with a point like that."

Set to grow angry again, Phrallet abruptly realized she was being indirectly complimented, and made no answer.

Drotninch, less tactfully, said, "Going back to where we were just now: you can very well have heat without fire, or at least without flame. Using a burning-glass is something else, because we assume the sun to be made of fire fiercer than what we can imitate down here. But if you rub something long and hard enough, it gets warm, and likewise air if you compress it with a bellower. Don't you know about that sort of thing on Voosla, Phrallet?" She sounded genuinely curious.

"You should know better than to ask"—unexpectedly from Lesh. "The People of the Sea did study heat and even flame at one time, using substances that protected their junqs and briqs from feeling the effect. But it was hard to keep a fire alight at sea, and eventually they lost interest because they didn't have any ore to melt, or sand for glass, and they could always trade for what they needed."

"That's right!" Phrallet agreed, and it was plain she was relaxing at long last.

Drotninch rattled her mandibles. "This gives me an idea. Do you think there's enough burnable material around here to start up a—what do they call it?—a furnace?"

"What for?" Byra countered.

"Well, in olden times they used fire to separate metal from ore, didn't they? Even if we can't use a concentration-culture, we might get at this poison using heat."

"Hmm! I'm inclined to doubt it," Byra said. "We don't yet know whether it's a simple substance, for one thing."

"If it weren't, and a very rare one, surely we'd have encountered it before?"

"Maybe we have," Lesh suggested. "Or at any rate its effects. I've never really believed that hot rock—let alone actual volcanoes—can be accounted for by saying that there's a leak from the core of the planet. For one thing the core must be too hot; for another, the magma would have to rise for many padlonglaqs, and I can't envisage channels for so much lava remaining open under the enormous pressures we know must exist down there."

"What does this have to do with—?" Drotninch had begun to say, when there was a rustle of foliage and Thilling arrived to join them.

Parting the leaves revealed that the new moon was rising, a narrow crescent, just about to disappear again as it crossed the Arc of Heaven.

"I wish we'd had time to force some of those special luminants Voosla brought," said the picturist as she settled in a vacant crotch. "Or that the moon were nearer full, or something. I spend too much of my working life in total darkness to be comfortable by mere starlight. It's not so bad if your maw is full, but ... Any of you manage to eat anything tonight?"

They all signed negative.

"Me neither. Never mind that, though. What annoys me most is that I can't examine my images properly before dawn. But I'm sure they're going to be full of smears and blurs again, and it isn't my fault. Any explanations?"

Drotninch summarized the discussion so far.

"Awb hit on that idea, did he?" Thilling said with approval. "I agree: he's a credit to his budder, and I'm glad I decided to take him on as my apprentice. Sorry I didn't ask you to help out this time, by the way, young'un, but you realize I have to be score-per-score certain that any flaws in the images are due to me, or some outside force. All right?"

"Yes, of course," Awb answered, trying not to swell with pride, and realizing this was just the kind of attitude he would have expected one of the true Jingfired to display.

"What I'm going to do tomorrow," Thilling resumed, "is a pure gamble, but if I'm right in my guess, then ... But wait a moment. My new apprentice is pretty quick on the uptake, so let's ask him. Awb, in my position, what would you do?"

Awb's pulsations seemed to come to a complete halt. Here in the dark his mind felt sluggish, and with his maw empty the problem was worse yet. Struggling with all his mental forces, fighting to distinguish what he could rationally justify from what was seeping up from wild imagination or even the utterly logic-free level of dreamness, he reviewed everything he had been told at the observatory site, and what he had seen on the way, and what Thilling had had time to teach him...

The silence stretched and stretched. Eventually, reverting to her usual mood, Phrallet said, "Not much use asking him, was it? Now if you'd asked me—"

"But I didn't," said the picturist with point. "Well, young'un?"

That insult from his budder had been like dawn breaking inside his mind. Awb said explosively, "Take some of your leaves and just lay them around the dam, see what shows on them without being put in a fixer!"

"Well, well, well!" Thilling said. "You got it! It looks as though that's the only way to detect the effects of the poison short of letting something be killed by it. I like Byra's idea that it's a kind of burning, I like the idea that it may have something to do with hot rocks and volcanoes, and I don't like the idea that it's getting to my insides without my being able to sense it. But that's about all we'll be able to do on this trip, isn't it, Drotninch?"

"I'm afraid so," the scholar confirmed. "We'll have to bring safe food not only for ourselves but for the mounts on our next visit, and someone is going to have to travel all the way to the headwaters of the warmest stream, and one way and another I'm not sure we can tackle the job properly before next year. And—Lesh—you know what I'm going to have to say next, don't you?"

"The work we've done at the observatory has gone for nothing," was the bitter answer. "It will have to be sited somewhere else."

She clenched her mantle tight around the branch she lay on, like a mariner preparing for a gale. They left her alone with her thoughts. But it was with deliberate loudness that Drotninch continued, "Still, one all-important purpose has been served. We have found something totally new on our own planet, which we sometimes imagine to have been exhaustively explored. It's well for us to be reminded now and then that the unforeseen can break out under our very pads. If we don't keep that constantly in mind, what's going to become of us when we venture into space?"

Very softly, and for Awb alone, Thilling said, "Spoken like one of the Jingfired...! Think about that, young'un. You still haven't told me what I'm most waiting to hear."

She stretched out and parted the overhanging leaves, and they all gazed up, except for Lesh, at the beautiful and terrifying fires of the Major Cluster, where since tune immemorial new stars had, slowly and implacably, crept into view.

VIII

"Might as well use my entire stock of leaves on this," Thilling told Awb as dawn broke. "If anything more important turns up during the trip, I shan't want to know ... We'll time the job by the sun; every score degrees it moves, we bring in one batch of 'em. Leave the bower set up so I can develop them as they come in."

Still baffled by the implied question the picturist expected him to answer, Awb helped her to lay out unexposed sheets by groups of five along the dam. But he found himself far more fascinated by what was happening in and on the lake. It was impossible to see more than a padlong below the surface, but here and there bubbles rose, and drifts of steam puffed up, and peculiar pale blue water-walkers scuttled hither and thither, avoiding the hottest spots but far more active than their cousins on cool rivers. As soon as Thilling let him go, he gathered up a few and offered them to Byra, who was packing every available container with specimens of flora and fauna.

"Where from exactly?" she demanded. "Near the dam? But how far from it?"

Why, she was a worse precisian than Axwep trying to balance Voosla's food-and-people accounts! But Awb preserved a courteous meekness.

"Between four and five padlongs from the thickest part of the yellow mud, where the bubbles rise most often."

"Hmm! That'll do very well! One thing I must give you, young'un: you have a keen eye on you. Yesterday that mutated winget, now this lot ... What I'd really like to find, though, is a thriving root-mass of the spillway plants. We need some clue to resistance against this poison. Without that I don't know what we'll do."

But could any resistance be found to it among the folk? What if the only possible adjustment they could make in this region was the one adopted by the natives, able to feed and breed but nothing more?

However, Awb kept such thoughts to himself. After all, the scientists did have behind them the resources of one of the planet's greatest centers of knowledge.

It was time to take Thilling the first batch of exposed leaves. When he delivered them, she said, "Drotninch wants you to collect samples of the yellow mud. She's going to load one of the mounts with it. I told her to make sure it's the one furthest from my stuff."

"How did yesterday's images come out?" Awb inquired.

"What makes you think they came out at all?" Thilling countered sourly, but fanned a quarter-score of them for his inspection. All were weirdly streaked and smeared.

"What am I looking at?" Awb whispered.

"Something scarcely any eye has seen before," was the muttered answer. "The telescopes they meant to build on Fangsharp Peak were supposed to gather so much light from such faint sources, no one could possibly sit and register it. So they planned to make them deliver their light to sheets like these, using astrotropes whose growth is controllable to a laqth of a clawide to keep the image steady. Oh, the effort they've wasted on breeding those 'tropes!"

"You sound as though the observatory is never going to be built, not here, not anywhere!" Awb cried.

"Maybe it won't. Because the only time I saw patternless faults like these on an unexposed image-leaf..."

She shook her mantle, returning the sheets to their pack. "It makes common-type sense, doesn't it, to grow observatories on mountain-tops? There are four or five such, and I'm an advisor to the one near Chisp. They called me in because even when they're using the finest leaves things go wrong. There are smudges, there are blurs, there are distortions. Often they spoil a whole dark's work, especially when the telescope is aimed at the Major Cluster."

"What causes them?" Awb clenched his claws.

"We think it's tiny particles of matter blasted out from the new stars forming so far away. And they carry with them something of the terrible stellar heat. At any rate, they burn their way into the leaves. But I never imagined that something at the bottom of a valley ... Hmm!"

As though struck by sudden insight, she turned back to the dark-bower, intent on developing the latest sheets.

"Go get Drotninch's mud-samples," she ordered. "But remember to time the next lot of leaves, too."

Awb hastened to comply. At least, down by the dam, he could be sure of avoiding Phrallet, who still seemed to harbour the suspicion that her heat-sore pads were owed to some sinister plot by Drotninch and the other scientists.

But there was something amiss.

He fought the knowledge for a long while, digging up the yellow mud, collecting the rest of the leaves at proper intervals and bringing them to the dark-bower, making himself as useful as he could to everybody.

Then, tiny as a falling star viewed through the wrong end of a spyglass, a spark crossed his eye.

Puzzled, he looked for more, but found only a red trace across his field of vision, rather as though he had gazed too long at something very bright but very narrow, like—

Like what? There was nothing it was like at all.

Simultaneously he became aware of a sensation akin to an itch, except that it wasn't one. It was just as annoying, but he couldn't work out where it was, other than very vaguely. And whoever heard of an itch in red-level pith, anyway? Determinedly he went on with his work, and shortly was rewarded by spotting another mutated water-walker, not blue this time, but pure white.

He dived after it and trapped it in his mandibles, and bore it to Byra in triumph.

Standing by as she inspected it under the microscope, he heard her say irritably, "Stop fidgeting, young'un! You look as though a mustiq got under your mantle ... Oh, this is even more ridiculous than the last one! I don't see how it can survive, let alone reproduce itself!"

He scarcely noticed the last comment. A mustiq under his mantle? Yes, that was a little like it. He'd been twitching without realizing until he had his attention drawn to it. He was pulsating out of rhythm with himself; instead of the normal ratios between mantle-ripple, gut-shift, breath-drawing, ichor-peristalsis and eye-flick which he was accustomed to, in the perfect proportions of bass, third, fifth, seventh and octave, he was shuddering as though about to burst.

Having his maw empty for so long, for the first time in his life, was proving to be a very odd experience indeed.

Yet if hunger were the sole explanation (and surely he hadn't gone without for long enough?)—

Oh, NO!

POISONED???

He peeled apart from himself, much like the brollicans that teachers on Voosla grew excited about when they chanced across a shoal of them so large the city had no time to eat the lot before a few could be salvaged for educational purposes. For scores-of-scores of years they had been providing real-time evidence for symbiosis, the phenomenon that underlay the folk's modern predicament.

Coevolution ... said something from the deep red level of his consciousness, but everyone knew that that level didn't deal in speech, only in hunger and breeding-need and the repair of vital organs.

(But who had told him that was true? Maybe someone would come along to tell him different, like Thilling! Maybe the exercises she had promised him, concerning dark-use, didn't refer only to outside-dark but inside-dark as well ...)

In the distance, though very close in time, like right now:

"Help!" (It was Byra's voice.) "Drotninch, Thilling, Phrallet, anybody! Awb's gone dreamish!"

Dreamish? Me? Me...?

But he didn't know who he was any longer. There wasn't a "myself" controlling the physical envelope known as Awb. There was a muddle of memory and imagination, a chaotic slew of information and sensory input, and what trace of identity did remain—thanks to his having been budded on a small but wealthy city, where no one in living memory had gone dreamish through simple hunger—was capable of no more than observation: as it were, "So this is what must have happened to our poor ancestors who multiplied themselves without making provision for proper nourishment! I'm amazed they ever clawed their way back out of the mental swamp they fell in, regardless of Gveest's best efforts, or the Jingfired's!"

Then even that last vestige of himself dissolved, and his pith started to react as though he were his own remotest forebear, assailed by predatory gigants and striking out at random in the faint hope that at least his body might block one monster's maw and choke it to death.

It took three of them to subdue his violent flailing.

Late that dark Thilling lay in a tree-crotch well away from the dam, which her images had convinced her was the chief source of danger, while the scientists wrangled among themselves. Awb had been temporarily quieted; Lesh had dispatched two of her assistants to find fruit and funqi from which nourishing juices could be extracted, at a safe distance from the lake, and herself administered a calmative from the first-aid pack she had brought. It was to be hoped that his youth and slightness of build accounted for his extreme vulnerability to—to whatever had afflicted him. At any rate the rest of them seemed to be in fair shape, with the exception, Thilling reflected cynically, of Phrallet, who was on the verge of hysteria. She kept saying over and over, "We must get out of here! We must go back at once! Who knows what damage is being wrought in our very pith? My pads are still hurting, you know!"

And when she found her companions ignoring that line of argument, she tried cajolement: "If only for the sake of my youngest budling, we must go back! Oh, I know I'm sometimes hard on him, but really I do care for him, and if he dies because of this..."

At which the others simply turned their backs in the most insulting fashion possible. So for some while now she had been sulking, which at least allowed the rest of them to debate the core of the problem.

Drotninch was saying, "I'm coming around to the conclusion that we not only have to deal with the poison per se, but also with its effects on living organisms, including disease germs. You know there's a theory that the New Star triggered off the latest round of female mimicry, the one which made so many of us too like males to bud anymore. Given what Thilling has told us about the resemblance between what she finds on her image-sheets and what happens when sheets are exposed at high altitude—"

Lesh cut in. "I've heard that theory, and to me it smacks of the rankest astrological superstition!"

Byra said heavily, "There's only one way of settling the matter. We're going to have to study this poison in vivo. Right now, of course, we only have one subject: Awb. But it's beyond a doubt that some at least of the same effect must be working in all of us."

Rousing from her apathy, Phrallet shouted, "What do you want us to do—stay here until we all collapse the way he did? You must be out of your pith! Anyway, I won't let you treat a budling of mine like a laboratory animal!"

Doing her best to disregard the interruption, Byra went on, "We can extrapolate from cutinates to some extent, of course, and I've taken samples from the mount that died, and with luck the rest of them will have been affected—"

"With luck?" Lesh echoed sardonically. "When I need every mount and draftimal I can lay claws on to rescue my expensive equipment from the observatory site? You're not killing any of my beasts for your researches, I'm afraid! In any case, mounts aren't enough like us, are they?"

Sighing, Byra admitted as much. "We'll have to rely on what we can learn by studying Awb, then, and since of course we all hope he'll make a quick recovery, that may not be very much. Still, we can call for volunteers who've been in the area since the project started, and that may help."

"You can get all the specimens you need," Phrallet said. "Why haven't you thought it through? If studying the poison in a living person means saving our lives—I mean Awb's life—you could just kidnap a few of the natives. They're worthless for anything else, aren't they?"

Thilling clenched her mantle in horror. Surely this group of civilized scientists must reject so hideous a notion out of claw? But no! To her infinite dismay she realized they were taking it seriously. Byra said after a pause, "It would certainly be very useful."

And Lesh chimed in: "We have plenty of nets! I'll get my staff on the job the moment we return!"

In that moment Thilling realized that she despised Phrallet more completely than anyone she had ever met or even heard of.

And what would Awb say when he learned that his life had been spared at such revolting cost?

But perhaps he would care no more than his budder.

IX

How everything had changed in three-score years! Not least, of course, thanks to the mutated diseases the workers from the abandoned World Observatory had carried away with them. Thilling shivered as she reflected on how vast a mystery those mutations had then seemed, how simple the explanation had proved to be once it was properly attacked...

Why was it that so many people declined to pay attention to such matters? Here in the crowded branchways of Voosla—a city transformed and twice enlarged since she last set pad on her—she knew without needing to be told that anyone she accosted at random would be as likely as not to dismiss her scientific knowledge out of claw, as totally irrelevant to their own concerns.

In the distant past, when there had been religions, it must have been similar for a traveler from afar; how had Jing reacted to those who honestly believed that the Arc of Heaven was the Maker's Sling, and shed meteors on the world as a warning of divine retribution? And here she was, under orders to confront a teacher whom his followers regarded as fit to be mentioned alongside Jing himself, even though he encouraged them to despise the greatest discoveries and inventions of his own lifetime.

If only the Jingfired had picked on someone else for this mission ... But their old acquaintance had tipped the balance; Thilling was forbidden to disobey.

She had no difficulty in locating the venue of Awb's daily meeting, of course. Scores-of-scores of people were making for it, so she simply let herself be carried along.

It was, she must admit, a considerable achievement for a mere male to have got himself regarded as his city's most outstanding bud, granted the use of the handsome open bower at the very center of Voosla which was normally reserved for public debates on matters of policy. She imagined it was seldom so packed for one of those. It was with relief that she noticed, as she made herself comfortable in an inconspicuous crotch, that she was not the only person present with the traces of old age on her mantle, though the vast majority of the attendance consisted of young'uns chattering away like piemaqs.

But they fell silent the instant Awb appeared: plumper than Thilling remembered, his mantle deeply grooved, his eye—like her own—less keen. Yet his voice was tremendously improved, and at his first utterance she felt she understood at least a little of what drew folk to him.

Persuasive or not, however, what he said was totally repugnant to her. He taught that no "proper" relationship, with one's community, even with one's budder or budlings—let alone the commensality of all living things—could be established without prior comprehension of oneself. Sometimes he urged people to starve in the midst of plenty, like the ancient sacerdotes; sometimes he expounded on ideas drawn from dream-ness, as though they warranted equal treatment with rational knowledge; frequently he declared that those who sought means to escape the planet were actually fleeing from true awareness of themselves.

And all this, Thilling thought bitterly, because of the load of guilt he had carried ever since he learned that Phrallet's monstrous scheme to kidnap those mindless northern natives and experiment on their living bodies had saved his life ... but not her own.

He spoke freely enough about his illness and recovery; what he never mentioned, according to her briefing—nor did he prove the contrary today—was the self-sacrifice of Drotninch and Eupril and Lesh, who had each in her respective way struggled to make sense of the heat arising in that yellow mud, and in less than a generation revolutionized the folk's understanding of matter. Above all, their legacy offered clues to the processes that lit the stars.

Because of them, and their successors, the chemistry of other elements than woodchar was at long last being studied thoroughly. The ancient use of fire had been resuscitated; brilliant young minds had been brought to bear on the questions posed by metal, glass, rock, plain ordinary water! A whole new universe of knowledge had been opened up. And did Awb care? Not by any clue or sign he gave!

Of course he did still hew to his belief that life among the People of the Sea was inherently superior to life on shore. To this fact he modestly attributed his remarkable success in treating deranged landlivers, whose behavior was sometimes dangerously abnormal even though the most delicate analyses revealed nothing amiss in their nerve-pith or ichor. More cynical, Thilling thought of the cleansing ocean breezes that bore away intrusive pheromones. Sea-travel had been regarded as beneficial long before Awb's reputation converted Voosla into the most sought-after of floating cities, in demand to touch at every continent in the course of every year. And she was sure Awb himself must be aware of that fact.

But if she were to mention it to those around her, would they be interested? Would they believe her? Most likely not. Awb and his disciples seemed to be set on creating a generation of young folk who cared as little for the past as for the future. Neither the study of history nor planning for the salvation of the species could attract them. They were assured that they need only study themselves, and all would be well, for ever and ever...

The meeting had assembled before sundown. Darkness overtook it while Awb was still answering questions. Suddenly Thilling noticed that something was distracting the crowd, and everyone was glancing upward. Copying their example, she realized why. There was a small yellow comet in the sky, but that was commonplace; what had drawn their gaze was a meteor storm, a horde of bright brief streaks coming by scores at a time.

She thought for a moment about challenging Awb to deny that that was a reminder of the doom the planet faced, another promise of the dense gas-cloud the sun was drifting towards. But she lacked the courage.

She remained meekly where she was until he was done, and then— equally meekly—made her way towards him, surrounded by a gaggle of his admirers. Most were young she'uns, doubtless hoping for a bud from so famous a teacher.

In old age her own sterility had become a source of gall to Thilling; she strove not to let it prey on her pith.

There was little chance, though, of actually reaching Awb in this small but dense throng, for everyone was respectfully lowering as they clustered about him, leaving no gaps for passage. Hating to make herself conspicuous, but seeing no alternative, she did the opposite and erected to full height ... such as it was at her age.

"Awb, it's Thilling! Do you remember me? We used to know each other many years ago!"

There was a startled pause, and all eyes turned on her. A whiff of hostility reached her—how dare this old'un claim acquaintance with the master? But then Awb replied, in a gruffer and lower voice than when addressing the crowd.

"I remember you. Wait until the rest have gone."

And he dismissed them with gentle shooing motions of his mantle. Disappointed but compliant, they wandered off.

When they were alone but for two thick-set individuals who appeared to be his permanent attendants, his age-dimmed eye surveyed her from crest to pad.

"Oh, yes. It is the same Thilling in spite of the time that's passed. Your voice has changed, but so has mine, I imagine ... Tell me, are you still subject to your delusion about being able to recruit people to the Jingfired?"

Delusion?

For an instant Thilling, who had devoted her entire life to the cause she regarded as the greatest in history, wished she might hurl herself bodily at him, shred his mantle with claws and mandibles before his companions could prevent her. But she conquered the impulse, as she had overcome so many before, and a gust of wind dispersed her betraying anger-stink.

With careful effort she said, "Why do you call it a delusion?"
