We were standing just at the edge of that great circular compartment that we had glimpsed from above, one hundreds of feet in diameter, the twilight about it dispelled somewhat in it by soft-glowing disks in its walls. In this great compartment there stood what seemed an immense circular table of metal, only a few feet in height, ring-like in form and with a clear circular space at its center. This great ring-table's edge was not more than a dozen or so feet from the compartment's circular wall, and ranged around it, on low seats between the ring-like table and the wall, were thirty disk-bodied Neptunians. Silent and almost motionless they sat there around the great ring-table, and I saw that upon the metal armor of each was a crimson circle like that of our leader, except that there was a crimson dot at its center, a symbol we had noted on no other Neptunian so far. And from each of the thirty there ran in toward the clear space at the ring-table's center a slender black wire-connection, attached by diverging connections to the body of each of the thirty. These thirty connections ended at the space at the ring-table's center, running there into a strange object or mechanism that stood in that space. It was composed of a great metal pedestal with straight sides, like an upright pillar, into which the thirty connections ran, while upon the pillar's top was supported a globe of metal somewhat greater in diameter than the pillar, being some five feet across. In this globe's side was a round opening, while set at two other points at opposite sides of it were what seemed inset diaphragms. From the supported globe came a fine hum, scarcely audible, and that was the only sound in the great compartment. The whole scene was strange--the towering black walls of the great circular compartment about us, the great ring-table in it and the thirty silent, motionless disk-bodied Neptunians seated around that table, and the giant globe on its pedestal at the table's central space. * * * * * As we stood there the Neptunian leader before us spoke in sharp snaps, as though explaining our presence, but not to the thirty around the table; it spoke to the great central globe of metal! In amazement we watched him, and then we saw that the globe was turning upon its pedestal, turning toward us a small circle of clear glass set in its opposite side, that surveyed us for the moment exactly like a single calm eye. Then the globe turned again, the opening in its side again facing us, and then from that opening came a staccato answer to our leader, a swift question, apparently, in the snapping speech-sounds of the Neptunians! The globe was hearing our captor's report, was questioning him concerning that report, while the thirty around the table uttered no sound, and turned not toward us! "Good God!" I muttered at that astounding spectacle. "That globe of metal, Marlin--it hears him, answers him! The thing must be alive!"
