Now the thrumming conversation of the creatures about us broke off, and one turned to the edge of the platform, touching a stud in the floor there. At once a circular section of the metal floor, some ten feet across, slid aside, revealing a round dark well of the same diameter, which apparently extended down into one of the great tower's four supporting columns. At the top of this shaft hung a small, square metal cage, or elevator, and into this we were shepherded at once, two of our captors entering the cage with us and keeping their fire-disks trained still upon us. There was the click of a switch, then a sudden roar of wind, and instantly the cage was shooting downward with tremendous speed. Only a moment we flashed down through the roaring darkness, and then the cage came to rest and a section of wall beside it slid aside, admitting a flood of dusky, crimson light. At once we stepped out, followed by our two guards. We were standing at the foot of a mighty column down which we had come, standing on the floor of a great, circular, flat-roofed room, in and out of which were moving scores of the globe-creatures. From the very center of the room, behind us, rose the fifty-foot thickness of the huge pillar, soaring up obliquely and disappearing through the building's roof, two hundred feet above. Except for the pillar and the hurrying figures around us the great room was quite bare and empty, lit only by high, narrow slits in its walls which admitted long, shafting bars of the crimson sunlight. I heard Hal Kur muttering his astonishment at the titanic scale on which all things in this strange world seemed planned, and then there came a thrumming order from our guards, who gestured pointedly toward a high doorway set in the room's wall opposite us. Obediently we started across the floor toward it. Passing through it, we found ourselves in a long, narrow corridor, apparently a connecting passage between another building and the one we had just left. There were windows on its sides, circular openings in the walls, and as we passed down the hall I glimpsed through these the city that lay around us, a vista of black streets and crimson gardens through which thronged other masses of the globe-creatures. Then, before I could see more, the corridor ended and we passed into a large anteroom occupied by a half-dozen of the globe-men, all armed with fire-disks which they trained instantly upon us.
