impossible! The equations of the Stream prove—" "I know. Now will you come over?" "Why didn't you say so in the first place? I'll bring the whole ship." Underwood cut off and switched to the Captain's line. "Captain Dawson? Underwood. Will you please take the ship to the vicinity of Asteroid C-428 as quickly as possible?" "I thought Doctor Phyfe—" "I'll answer for it. Please move the vessel." Captain Dawson acceded. His instructions were to place the ship at Underwood's disposal. Soundlessly and invisibly, the distortion fields leaped into space about the massive laboratory ship and the Lavoisier moved effortlessly through the void. Its perfect inertia controls left no evidence of its motion apparent to the occupants with the exception of the navigators and pilots. The hundreds of delicate pieces of equipment in Underwood's laboratories remained as steadfast as if anchored to tons of steel and concrete deep beneath the surface of Earth. Twenty minutes later they hove in sight of the small, black asteroid that glistened in the faint light of the faraway Sun. The spacesuited figures of Terry Bernard and his assistant, Batch Fagin, clung to the surface, moving about like flies on a blackened, frozen apple. Underwood was already in the scooter lock, astride the little spacescooter which they used for transportation between ships of the expedition and between asteroids. The pilot jockeyed the Lavoisier as near as safely desirable, then signaled Underwood. The physicist pressed the control that opened the lock in the side of the vessel. The scooter shot out into space, bearing him astride it. "Ride 'em, cowboy!" Terry Bernard yelled into the intercom. He gave a wild cowboy yell that pierced Underwood's ears. "Watch out that thing doesn't turn turtle with you." Underwood grinned to himself. He said, "Your attitude convinces me of a long held theory that archeology is no science. Anyway, if your story of a material impervious to the Atom Stream is wrong, you'd better get a good alibi. Phyfe had some work he wanted to do aboard today." "Come and see for yourself. This is it."
