Diane rose, smiling pertly. "All right, so I'm untidy. Well--show them, Lancelot!" Biggs rose. He looked carefully at the clock; then at the statometer. He moved to the intercommunicating system, gargled a word to the engine room below. "Mr. Garrity, would you be kind enough to revolve the ship?" Hanson yelled, "Re--revolve the--Hey! Grab him, somebody! He's gone space-batty! He's slipped his gravs!" From below there came the sound of the rotors going into operation. We couldn't feel anything, of course. The ship's artificial gravs hold you firm to the floor no matter which is top or bottom in space. There being no such thing. After a minute Biggs said, "Thank you, Mr. Garrity. Now, if you will be kind enough to reverse gravs and throw out the top-deck repulsion beams?" Garrity obeyed. There came a sudden shock; everything movable in the room moved. Including me. I fell to the middle of the room, hung there gaping, weightless, the same as everyone else. The _Saturn_ lurched and shuddered; it felt as if something trembled along her beams for a brief instant. Then, suddenly, we were literally scorching through space again! _Real_ space--not that phoney hyper-stuff of the vacuole. Biggs yelled, "Normal gravs, Garrity! Alter course to point-six-one for three minutes, then land...." Cap Hanson screamed, "What the--what's going on here? Land? What do you mean--_land_!" And Lancelot Biggs said, "If you'll be kind enough to look through the _perilens_, Captain...." It was Earth. Just as big as life and three times as natural. A hop-skip-and-jump beneath us. We had made the Venus-to-Earth shuttle in four days, eight hours! * * * * * Afterward, when the Government committee had left, congratulating us upon having won the allotment, and the IPS officials had departed like a trio of overgrown sunbeams on legs, Hanson, Todd, Diane, Biggs and I were alone in the control turret of the _Saturn_. To the smiling First Mate, Cap Hanson said, "Biggs, this business of apologizin' to you after every crackpot adventure is gettin' monotonous. But I do it again--with the provision that you tell me how the hell an' what the hell happened." Biggs fidgeted and looked uncomfortable. "Well, to begin with, I knew we were licked if we tried to race the _Slipstream_ in any normal fashion--" "The proper word," I interjected, "is skunked." "Yes. So when I saw what happened to the _Slipstream_ when it fell into the vacuole, I saw a way in which we might possibly come out on top. I didn't want to explain, though, for if the method failed, Captain Hanson might be reprimanded for permitting the trial--" "Method?" demanded Hanson. "What method?" "Piggy-back!" grinned Biggs. "You'll remember that we commented on the amazing speed with which the vacuole was traveling through space. A speed greater than our own; even greater than that of the _Slipstream_.
