That question was soon answered. The big Venusian who had admitted us to the room, and who apparently was the sole guardian of this valuable chamber with its vital apparatus, stepped ahead of us and pointed one of the round objects he carried at the side of the flyer. Instantly two doors flew out, making an opening about four feet wide and six feet high into the projectile. Stooping, Oomlag entered, and I followed close behind him. Without a sound, the doors shut behind us. At last I was actually inside the wonderful space flyer that had brought this vanguard of horrible, super-intelligent beings to conquer our helpless earth! With hardly controlled excitement and curiosity I gazed around. We were standing in a brilliantly lighted octagonal chamber some twenty-five feet across, with a metallic ceiling about twelve feet from the floor. In the center of this ceiling was a circular opening about six feet in diameter through which extended a round, perpendicular shaft like the slide pole in a fire station. On each side, opposite the walls of the chamber, were tall metal devices, for all the world like elongated hour glasses, extending from floor to ceiling. On the neck of each was an intricate series of valves and pipes, and from the base of each “hour glass” innumerable small tubes led to the walls. Although I couldn’t hear a sound, I seemed to be conscious of a sort of vibration that made me sense the powerful forces that were at work. At the base of the pole in the center was a round platform which, as I looked, slid noiselessly out of sight up the pole, descending in a few seconds with a couple of Venusians. These, after a curious glance at me, busied themselves inspecting the machinery, reading dials, and moving various handles on the different valves. Oomlag had been watching me with smug satisfaction, evidently deriving much amusement from my open-mouthed expression of amazement. “Yes, I thought you would be entertained by this little visit,” he chuckled. “Gaze upon the highest development of our genius. Simply by making a change in the amount of ‘Venusite’ introduced into what you might call the condensing tubes, the power generated is controlled. You already know the power of ‘Venusite’ when you realize that it brought us from our planet to yours; you can imagine, then, what very minute quantities are needed to supply power. “These tubes leading from the base of these generators carry the concentrated power impulses to the tubes you saw on the outside of the flyer. These in turn bombard the round objects you saw placed near the walls of the room, which operate to diffuse the power beam in various directions through the workings.
