puted in Washington."
He added that inside each sphere was a "pulsemaker." This would produce
changes in the pressure of the hydraulic fluid by affecting the kinetic
energy of the fluid's atoms.
The pressure changes would then be enormously magnified in the four
hydraulic output drivers. When the unit was embedded in rock,
underground, the huge pistons would send out counter shock waves through
the earth's crust to neutralize the enemy waves.
"Wow!" Hank Sterling was breathless at the sheer scope of the young
scientist's newest invention. "I'll get hot on the job right away."
After forty-eight hours of round-the-clock work, the equipment was
ready. Tom conferred by telephone with both Dr. Miles in the Bureau of
Mines and Bernt Ahlgren in the Pentagon. He had already chosen the spots
for the detector-transmitter check points.
Tom told the men that he believed the best spot for the Quakelizor
itself was on a certain government reservation in Colorado. A deep
underground cave there would provide a perfect site.
"We'll be close enough to the San Andreas fault to prevent a really
huge-scale disaster," Tom explained. "And the Rocky Mountain structure
will give us a good bedrock medium for shooting out waves anywhere
across the continent."
Dr. Miles and Ahlgren agreed enthusiastically. Tom and the two
scientists spoke over a three-way telephone hookup--with automatic
scramblers to counter the danger of enemy monitors--laying plans to
install the equipment. Ahlgren agreed to fly a technical crew out to the
spot in Colorado which Tom had named.
The next day, Tom, Hank, and several top Enterprises' engineers,
including Art Wiltessa, took off in the _Sky Queen_. This was Tom's huge
atomic-powered Flying Lab. The massive plane flew at supersonic speeds
and was equipped with jet lifters for vertical take-off or hovering.
A Whirling Duck heliplane, loaded with communications equipment,
accompanied the _Sky Queen_. In little more than an hour, the two craft
touched down in a rugged Colorado canyon. The government technical crew
was already on hand.
"Glad to know you," Tom said, shaking hands with the engineer in charge.
He introduced his own men and added, "Better roll up your sleeves. This
job is going to take plenty of oomph!"
The parts of the Quakelizor were unloaded from the _Sky Queen_ onto
dollies. Then the group, armed with bull's-eye lanterns, flashlights,
and walkie-talkies, hauled the parts by tractor
