"You sleep, Arcot. I'll prepare the materials for you," suggested Morey. So Arcot and Wade went to sleep, while Morey and the Talsonian and Torlos worked. First Morey bound the _Ancient Mariner_ to the frame of the time apparatus, safely away from the four luminous balls, broadcasters of the time field. Then he shut off the attractive ray, and bound himself in the operator's seat of the apparatus of the artificial matter machine. A plane of artificial matter formed, and a stretch of rock rose under its lift as it cleft the rock apart. A great cleared, level space resulted. Other artificial matter enclosed the rock, and the fragments cut free were treated under tremendous pressure. In a few moments a second enormous mass of cosmium was formed. For three hours Morey worked steadily, building a tremendous reserve of materials. Lux metal he did not make, but relux, the infusible, perfect conductor, and cosmium in tremendous masses, he did make. And he made some great blocks of oxygen from the rock, transmuting the atoms, and stored it frozen on the plane, with liquid hydrogen in huge tanks, and some metals that would be needed. Then he slept while they waited for Arcot. Eight hours after he had lain down, Arcot was up, and ate his breakfast. He set to work at once with the machine. It didn't suit him, it seemed, and first he made a new tool, a small ship that could move about, propelled by a piece of artificial matter, and the entire ship was a tremendously greater artificial matter machine, with a greater power than before! His thoughts, far faster than hands could move, built up the gigantic hull of the new ship, and put in the rooms, and the brace members in less than twelve hours. A titanic shell of eight-inch cosmium, a space, with braces of the same nonconductor of heat, cosmium, and a two inch inner hull. A tiny space in the gigantic hull, a space less than one thousand cubic feet in dimension was the control and living quarters. It was held now on great cosmium springs, but Arcot was not by any means through. One man must do all the work, for one brain must design it, and though he received the constant advice and help of Morey and the others, it was his brain that pictured the thing that was built. At last the hull was completed. A single, glistening tube, of enormous bulk, a mile in length, a thousand feet in diameter. Yet nearly all of that great bulk would be used immediately. Some room would be left for additional apparatus they might care to install. Spare parts they did not have to carry--they could make their own from the energy abounding in space.
