Lan Sohn Wen considered this for a moment, and finally nodded his head in acquiescence. "That is an excellent plan," he said, and then he detailed two warriors to stand guard; and arranged for their relief, after which he wished us good night and departed with his warriors.

I have never seen such courteous and considerate people as the Orovars; it might almost be a pleasure to have one's throat slit by one of them, he would be so polite about it. They are the absolute opposites of their hereditary enemies, the green men; for these are endowed with neither courtesy, consideration, nor kindness. They are cold, cruel, abysmal brutes to whom love is unknown and whose creed is hate. Nevertheless, the pits of Horz was not a pleasant place. The dust of ages lay upon the ramp down which we walked. From its end a corridor stretched away beyond the limits of our torchlight. It was a wide corridor, with doors opening from it on either side. These, I presumed, were the dungeons where ancient jeddaks had confined their enemies. I asked Pan Dan Chee.

"Probably," he said, "though our jeddaks have never used them."

"Have they never had enemies?" I asked.

"Certainly, but they have considered it cruel to imprison men in dark holes like this; so they have always destroyed them immediately they were suspected of being enemies."

"Then why are the pits here?" I demanded.

"Oh, they were built when the city was built, perhaps a million years ago, perhaps more. It just chanced that the citadel was built around the entrance."

I glanced into one of the dungeons. A mouldering skeleton lay upon the floor, the rusted irons that had secured it to the wall lying among its bones. In the next dungeon were three skeletons and two magnificently carved, metal bound chests. As Pan Dan Chee raised the lid of one of them I could scarce repress a gasp of astonishment and admiration. The chest was filled with magnificent gems in settings of elaborate beauty, specimens of forgotten arts, the handicraft of master craftsmen who had lived a million years ago. I think that nothing that I had ever seen before had so impressed me. And it was depressing, for these jewels had been worn by lovely women and brave men who had disappeared into an oblivion so complete that not even a memory of them remained.

My reverie was interrupted by the sound of shuffling feet behind me. I wheeled; and, instinctively, my hand flew to where the hilt of a sword should have been but was not. Facing me, and ready to spring upon me, was the largest ulsio I had ever seen.
