Huge as she was, there was no waste space--her design was as compact as that of a fine radio set. The living quarters were grouped closely about the central compartment, which housed the power plants, the many ray generators and projectors, and the myriads of controls of the marvelous mechanism for the projection and direction of fifth-order rays. Several large compartments were devoted to the machinery which automatically serviced the vessel--refrigerators, heaters, generators and purifiers for water and air, and the numberless other mechanisms which would make the cruiser a comfortable and secure home, as well as an invincible battleship, in the heatless, lightless, airless, matterless waste of illimitable, inter-galactic space. Many compartments were for the storage of food-supplies, and these were even then being filled by forces under the able direction of the first of Chemistry.
"All the comforts of home, even to the labels," Seaton grinned, as he read "Dole No. 1" upon cans of pineapple which had never been within thousands of light-years of the Hawaiian Islands, and saw quarter after quarter of fresh meat going into the freezer room from a planet upon which no animal other than man had existed for many thousands of years. Nearly all of the remaining millions of cubic feet of space were for the storage of uranium for power, a few rooms already having been filled with ingot inoson for repairs. Between the many bulkheads that divided the ship into numberless airtight sections, and between the many concentric skins of purple metal that rendered the vessel space-worthy and sound, even though slabs many feet thick were to be shown off in any direction--in every nook and cranny could be stored the metal to keep those voracious generators full-fed, no matter how long or how severe the demand for power. Every room was connected through a series of tubular tunnels, along which force-propelled cars or elevators slid smoothly--tubes whose walls fell together into air-tight seals at any point, in case of a rupture.
As they made their way back to the great control-room room of the vessel, they saw something that because of its small size and clear transparency they had not previously seen. Below that room, not too near the outer skin, in a specially-built spherical launching space, there was _Skylark Two_, completely equipped and ready for an interstellar journey on her own account!
