Down ramp after ramp we were conducted to the uttermost depths of the palace pits and then into a great chamber where I saw Haj Osis sitting upon a throne, surrounded again by his chiefs and his courtiers as he had been upon the occasion that he had interviewed me. Opposite the Jed, and in the middle of the chamber, hung a great iron cage, suspended from a heavy block set in the ceiling. Into this cage we were roughly pushed; the door was closed and secured with a large lock. I wondered what it was all about and what this had to do with The Death, and while I wondered a dozen men pushed a huge trap door from beneath the cage. A rush of cold, clammy air enveloped us and I experienced a chill that seemed to enter my marrow, as though I lay in the cold arms of death. Hollow moans and groans came faintly to my ears and I knew that we were above the pits where The Death lay. No word was spoken within the chamber, but at a signal from Haj Osis strong men lowered the cage slowly into the aperture beneath us. Here the cold and the damp were more obvious and penetrating than before, while the ghastly sounds appeared to redouble in volume. Down, down we slid into an abyss of darkness. The horror of the silence in the chamber above was forgotten in the horror of the pandemonium of uncanny sounds that rose from beneath. How far we were lowered thus I may not even guess, but to Nur An it seemed at least a thousand feet and then we commenced to detect a slight luminosity about us. The moaning and the groaning had become a constant roar. As we approached, it seemed less like moans and groans and more like the sound of wind and rushing waters. Suddenly, without the slightest warning, the bottom of the cage, which evidently must have been hinged upon one side, and held by a catch that could be sprung from above, swung downward. It happened so quickly that we hardly had time for conjecture before we were plunged into rushing water. As I rose to the surface I discovered that I could see. Wherever we were, it was not shrouded in impenetrable darkness, but was lighted dimly. Almost immediately Nur An's head bobbed up at arm's length from me. A strong current was bearing us onward and I realized at once that we were in the grip of a great underground river, one of those to which the remaining waters of dying Barsoom have receded. In the distance I descried a shoreline dimly visible in the subdued light, and, shouting to Nur An to follow me, I struck out toward it. The water was cold, but not sufficiently so to alarm me and I had no doubt but that we would reach the shore.
