"Well, Fred, what do you know?" Cleveland asked, as soon as greetings
had been exchanged. "How do the various reports dovetail together? I
know that you couldn't tell me anything on the wave, but there's no
danger of eavesdroppers _here_."

"You can't tell," Rodebush soberly replied. "We're just beginning to
wake up to the fact that there are a lot of things we don't know
anything about. Better wait until we're back at the Hill. We have a full
set of ultra-screens around there now. There's a couple of other good
reasons, too--it would be better for both of us to go over the whole
thing with Virgil, from the ground up; and we can't do any more talking,
anyway. Our orders are to get back there at maximum, and you know what
that means aboard the _Sliver_. Strap yourself solid in that
shock-absorber there, and here's a pair of ear-plugs."

"When the _Sliver_ really cuts loose it means a rough party, all right,"
Cleveland assented, snapping about his body the heavy spring-straps of
his deeply cushioned seat, "but I'm just as anxious to get back to the
Hill as anybody can be to get me there. All set."

Rodebush waved his hand at the pilot and the purring whisper of the
exhausts changed instantly to a deafening, continuous explosion. The men
were pressed deeply into their shock-absorbing chairs as the _Silver
Sliver_ spun around her longitudinal axis and darted away from the
_Chicago_ with such a tremendous acceleration that the spherical warship
seemed to be standing still in space. In due time the calculated
mid-point was reached, the slim space-plane rolled over again, and, mad
acceleration now reversed, rushed on toward the earth, but with
constantly diminishing speed. Finally a measurable atmospheric pressure
was encountered, the needle prow dipped downward, and the _Silver
Sliver_ shot forward upon her tiny wings and vanes, nose-rockets now
drumming in staccato thunder. Her metal grew hot: dull red, bright red
yellow, blinding white; but it neither melted nor burned. The pilot's
calculations had been sound, and though the limiting point of safety of
temperature was reached and steadily held, it was not exceeded. As the
density of the air increased so decreased the velocity of the man-made
meteorite. So it was that a dazzling lance of fire sped high over
Seattle, lower over Spokane, and hurled itself eastward, a furiously
flaming arrow; slanting downward in a long, screaming dive toward the
heart of the
