TOM SWIFT AND HIS ULTRASONIC CYCLOPLANE


CHAPTER I
THE WEIRD FIGURE

"You mean this little gadget can rev up a big enough storm to fly your new
cycloplane?"
Through the greenish quartz-glass window of his protective helmet, Bud
Barclay stared in amazement at his pal, Tom Swift.
The young inventor chuckled. "An ultrasonic storm, Bud. You can't see it or
hear it, but it packs a terrific wallop!"
The two eighteen-year-olds and Hank Sterling, the blond, rugged chief
patternmaker of Swift Enterprises, were in Tom's private laboratory, testing a
small ultrasonic generator which Tom had designed. All three wore special fiber-
glass helmets and gauntlets to protect them from the dangerous but invisible
pulsations of silent energy.
"As the electric current oscillates, this device beams out intensely powerful
sound waves-far above the range of human hearing," Tom explained.

All eyes focused on the gleaming steel cylinder which housed the generator.
"Sure looks harmless enough," Bud remarked.
"Don't let its looks fool you, fly boy!" Tom retorted. "Those ceramic disks in
there are vibrating over five million times a second. With waves of that frequency,
you can-"
"Tom! Look out!"
