Spring twilight was mounting during the first two weeks of June. The spring thaws were at hand. On June 13 we made our final inspection of the vehicle to be sure its equipment was complete. It was a small affair--as small as the one in which Zetta had arrived. And similar in shape--a flattened globe twenty-one feet in vertical diameter and thirty feet across its middle width. The thin shell of alexite gave it a dull gleaming white color. The exterior was reinforced with a thick, rolled belt of alexite like an equator around the globe's bulging middle. There were two vertical reinforcing circular bands; passing through its poles they divided its surface into four equal segments. Into each of these segments two small bull's-eye windows were set, one directly above the other. And in one segment, near the bottom, was a small, narrow door. The top and bottom of the globe were flattened to a level area some six feet square, as though a section had been neatly sliced off, to form a small lower floor and a small roof. Each was set with a bull's-eye glass windowpane. Such was the exterior aspect of our vehicle. I chanced to stand alone for a moment a few hours before our start, regarding it as it lay in the small stone room which had been built to house it. A tiny little world! Little white globe, so soon to be whirling through space with its three human inhabitants! And I was to be one of the three! The globe's interior was reinforced with a lining of alexite ribs, and a brittle wire mesh cast into the alexite shell. It was tested for pressure; in the vacuum of space the outward pressure of our air content would have exploded a shell less strongly built. Father had calculated all this; his calculations proved correct; we had a wide margin of safety. The globe inside was divided by two horizontal floorings into three compartments. The lowest one, to which the narrow doorway gave entrance, had a floor six feet square, bulging concave walls, and a ceiling some seven feet above the floor. This compartment was our instrument room, and observatory. It had four side windows, and the lower window which comprised its floor. Between the side windows, the instruments were fitted in racks. The control table was here, and a portion of the navigating mechanism. The middle story--much the largest of the three--contained our sleeping cots, our meager cooking arrangements, our food stock, and most of the mechanical apparatus for the navigating of the globe. The upper compartment, in size and shape like the lower, held our personal effects, our water supply, heating instruments, and the Regnalt-Dillon air purifiers, with the pumps, fans and distributors. In flight, this would always remain the upper segment of the globe; we would turn over after leaving the earth and fall toward Xenephrene.
