At last it was up for operation. The artificial matter apparatus was operated by cosmic power, and controlled by mental operation, or by mathematical formula as they pleased. Immediately Arcot set to work. A giant hollow cylinder drilled a great hole completely through the thin, curved surface of the ancient planetary block, through twelve miles of solid rock--a cylinder of artificial matter created on a scale possible only to cosmic power. The cylinder, half a mile across, contained a huge plug of matter. Then the artificial matter contracted swiftly, compressing the matter, and simultaneously treating it with the tremendous fields that changed its energy form. In seconds it was a tremendous mass of cosmium. A second smaller cylinder bored a plug from the rock, and worked on it. A huge mass of relux resulted. Now other artificial matter tools set to work at Arcot's bidding, and cut pieces from his huge masses of raw materials, and literally, quick as thought, built a great framework of them, anchored in the solid rock of the planetoid. Then a tremendous plane of matter formed, and neatly bisected the planetoid, two great flat pieces of rock were left where one had been--miles across, miles thick--planetary chips. On the great framework that had been constructed, four tall shafts of cosmium appeared, and each was a hollow tube, up the center of which ran a huge cable of relux. At the peak of each mile-high shaft was a great globe. Now in the framework below things were materializing as Arcot's flying thoughts arranged them--great tubes of cosmium with relux element--huge coils of relux conductors, insulated with microscopic but impenetrable layers of cosmium. Still, for all his swiftness of mind and accuracy of thought, he had to correct two mistakes in all his work. It was nearly an hour before the thing was finished. Then, two hundred feet long, a hundred wide, and fifty in height, the great mechanism was completed, the tall columns rising from four corners of the greater framework that supported it. Then, into it, Arcot turned the powers of the cosmos. The stars in the airless space wavered and danced as though seen through a thick atmosphere. Tingling power ran through them as it flowed into the tremendous coils. For thirty seconds--then the heavens were as before. At last Arcot spoke. Through the radio communicators, and through the thought-channels, his ideas came as he took off the headpiece. "It's done now, and we can rest." There was a tremendous crash from within the apparatus. The heavens reeled before them, and shifted, then were still, but the stars were changed. The sun shone weirdly, and the stars were altered. "That is a time shifting apparatus on a slightly larger scale," replied Arcot to Torlos' question, "and is designed to give us a chance to work. Come on, let's sleep. A week here should be a few minutes of Earthtime."
