"But your work here is finished, Eliot," Carse went on. "If only we can get to Earth safely, with Ku Sui and the brains in their new bodies, we will have achieved everything we wanted to achieve. We have proof of the crime done you, and we have Ku Sui, too. Your position will be restored and the blame put where it belongs. But we must leave for Earth at once! God knows how near the asteroid is, or who's on it." "All right, Carse." The scientist got up. "What are your instructions?" Ban Wilson appeared in the door, reporting that all the men had been accounted for and awakened. Carse started the wheels moving. "Everything of value here must be transported aboard the ship. Eliot, you know better than I what to take, so you'll assume charge of the loading. Ban, you and all the men save two of Eliot's assistants will help. I'll need them to move the bodies. Send them to me in the laboratory. But first, be sure Ku Sui and his four men are safely confined. All right; let's go." Within half an hour the general evacuation was finished and the ship loaded. * * * * * The _Sandra_, Leithgow's ship, bearing his daughter's name, was a sturdy vessel designed more for comfort and utility than speed, and so her appointments, including offensive and defensive weapons, though modern were limited. Her commodious cargo-holds were easily capable of accommodating all of the Master Scientist's laboratory instruments and devices, the volumes of his extensive library, his great mass of personal papers and more intimate effects; all the more important stores of the place, too, and its furnishings. The laboratory and its surrounding rooms were pretty well stripped. The largest of the _Sandra's_ cabins was transformed under the direction of Leithgow into a hospital bay, and the five cots bearing the prostrate, unconscious bodies of the patients put there. Though hastily improvised, this hospital was complete, as fully equipped and nearly as efficient as if it were on Earth and not in the belly of a space-ship. The chances of the patients for complete recovery were not diminished in any way by the sudden necessity for flight. In a second, much smaller cabin, Dr. Ku Sui was confined by himself. Its walls, of course, were of metal, and there was no possible means of exit from it save by the door, which bore double locks. The Eurasian, silent and drugged and stupid, immediately stretched his tall form out on the single berth and in seconds was again sound asleep. A third cabin was made over to his four assistants. With everything completed, the underground refuge bare of articles of value and the _Sandra_ stored and made ready for the long trip, the inner door of the exit tube swung open, and the ship slid slowly out of her cradle and into the water chamber for the last time. Her flight to Earth had begun.
