I swung back to him. In the moonlight at the laboratory window a face showed behind the filmy curtains--a man's face peering in at us. It was just an instant glimpse.... Staring, wild, red-rimmed eyes--the face wearing a bluish stubble of beard. By no chance could it have been the person who had escaped me in the corridor. In that second, I dashed for the window. The face had gone. I got there only in time to see a dark blob scurrying away into the shadows of the moonlit woods. II "All ready, Dr. Livingston," I said. "Eh? Oh, yes. Well, that's fine, John. We'll start at once." "I checked the ventilators," Duroh said. The big, beetle-browed Peter Duroh--dark-haired, handsome young giant who had been working for us nearly a year--stood beside me. It was the great night--our time of departure at last had arrived, with the little _Planeteer_ glistening and ready. To you who read this, familiar now with the great finned cylinders which the last half century has produced on earth for the conquest of Interplanetary space, our little space-ship was inadequate and queer indeed. Unlike modern vessels, Dr. Livingston had built the _Planeteer_ in the shape of a huge bell-like globe. Huge, to us then. But its maximum equatorial diameter was a scant fifty feet. Strange little ship indeed. Its interior was of three stories--the largest--the middle one--our several rooms of living quarters, ample enough for four of us. Below that, in the base, were the mechanism rooms. And the top level, fairly near the apex, was in effect a mere circular turret, with a glassite dome over it completing that segment of the outer shell. It is not my purpose here to describe Dr. Livingston's pioneer mechanisms. All that is technological history in the chronicles of the development of space-navigation. But I do wish to point out that Dr. Livingston, in his essentials of mechanism, has not been improved upon even in this last half century. The _Planeteer_ was double-shelled, the six-inch space between the reinforced walls containing the swiftly vibrating, oscillating electronic current now known as the Erentz principle--the absorption of the outer pressure, translated by the swiftly flying electrons of the current into harmless kinetic energy. And we had, in segments, throughout the globe-shaped walls, gravity plates for the neutralization of gravity; its intensification; and the negative force of repulsion. We had air-renewers--antiquated now, I admit--but still very serviceable to us; and ventilating and temperature systems. We had no electronic rocket-streams for atmospheric flight; that, as you all know, came much later. It was, by earth-time, just midnight when we were ready to start. Dr. Livingston was excited, confused now that the time was at hand. But the other three of us, outwardly at least, were calm enough, eager only to be sure every preparation was in order.
