"After our flight through space, automatically controlled, by the way, on Venus, we landed here. With our thoque disintegrator, we bored a passageway to the surface of this great sphere. Then we entered the car, rose to the top of the passageway, and discovered you. "That is a brief synopsis of our actions--and it must suffice! Ask no questions; we do not wish to be disturbed by the blind gropings of your primitive mind!" There was a cold finality in the Venerian's voice that convinced Parkinson that for the moment, at least, he had better forget the many questions that had surged up in his mind. The Venerian leader spoke again. "From our observations of your mind, we know that you have not had food or water for a rather lengthy period of time. It is not our purpose to starve you: you shall eat and drink." A minute later Parkinson sat at a very high table in one of the rooms, drinking water from Venus, and eating the fare of an alien world. * * * * * Days passed by, merging into weeks, while Parkinson lost all track of time. The bacteriologist's existence became a ceaseless round of toil. The Venerian had said that he would be given some measure of freedom, because he would be of use to them; he had not been with them long ere he learned what that use was. One of the rooms was filled with great slabs of thoque; it was Parkinson's task to carry the slabs to the vehicle at the base of the shaft, one by one; to rise to the surface with them, accompanied by two of the men--the third was working on the surface--and there unload them. Day after day this continued. Hope of escaping was almost dead in Parkinson's breast, because he was constantly under the surveillance of those hard, blue eyes. Only one thing kept hope alive: by watching the Venerians operate the car, he was slowly gaining a knowledge of the meaning of the many buttons in the wall. Some day, if an opportunity came, he meant to be ready to take advantage of it. Once, shortly after his monotonous toil began, Parkinson experienced a great flare of hope for deliverance. They had just brought another slab to the surface, when a steamer appeared above the horizon. It was far away, but its crew must surely have seen the island. But his expectations were short-lived. One of the three drew from beneath his tight-fitting, white garments a little, metal object, a long tube, with a handle at one end, and pointed it at the vessel. For a moment he held it thus, moving it slowly backward and forward: then he returned it to its place of concealment, and turned away with an air of indifference. And Parkinson saw the ship burst suddenly into flame, a few minutes later to sink beneath the waves. * * * * *
