work so wonderful must lead to something quite as wonderful I knew. What was it? I went on.
“At regular intervals I had passed the mouths of small caves. There would be three thousand steps and then an opening, three thousand steps more and an opening—and so on and on. Late that afternoon I stopped before one of these clefts. I suppose I had gone then three miles down the pit, although the angles were such that I had walked in all fully ten miles. I examined the entrance. On each side was carved the same figures as on the great portals at the lip of the pit. But now they were standing face forward, the arms outstretched with their disks, as though holding something back from the shaft itself. Now, too, their faces were covered with veils and there were no hideous shapes behind them.
“I went inside the cave. It ran back for twenty yards like a burrow. It was dry and perfectly light. I could see, outside, the blue haze rising upward like a column. I felt an extraordinary sense of security, although I had not been conscious of any fear. I felt that the figures at the entrance were guardians—but against what? I felt so secure that even curiosity on this point was dulled.
“The blue haze thickened and grew faintly luminescent. I fancied that it was dusk above. I ate and drank a little and slept. When I awoke the blue had lightened again, and I fancied it was dawn above. I went on. I forgot the gulf yawning at my side. I felt no fatigue and little hunger or thirst, although I had drunk and eaten sparingly. That night I spent within another of the caves. And at dawn I descended again.
“It was late that day when I first saw the city—”
He was silent for a time.
“The city,” he said at last, “the city of the pit! But not such a city as you have ever seen—nor any other man who has lived to tell of it. The pit, I think, must be shaped like a bottle; the opening before the five peaks is the neck. But how wide the bottom is I do not know—thousands of miles, maybe. And what may lie behind the city—I do not know.
“I had begun to catch little glints of light far down in the blue. Then I saw the tops of—trees, I suppose they are. But not our kind of trees— unpleasant, reptilian trees. They reared themselves on high, thin trunks and their tops were nests of thick tendrils with ugly little leaves like narrow heads—or snake heads.
“The trees were red, a vivid, angry red. Here and there I began to glimpse spots of shining yellow. I knew these were water because I could see things breaking through their surface—or at least I could see the splash and ripple but what it was that disturbed them I never saw.
“Straight beneath me was the city. Mile after mile of closely packed cylinders that lay upon their sides in pyramids of three, of five—of dozens— piled upon each other. It is so hard to make you see what that city is like—look, suppose you have water pipes of a certain length and first you lay three of them side by side and on top of them you place two and on these two one; or suppose you take five for a foundation and place on these four and then three, then two and then one. Do you see? That was the way they looked.
“And they were topped by towers, by minarets, by flares, by fans and twisted monstrosities. They gleamed as though coated with pale rose flame. Beside them the venomous red trees raised themselves like the heads of hydras guarding nests of gigantic jeweled and sleeping worms!
“A few feet beneath me the stairway jutted out into a titanic arch, unearthly as the span that bridges Hell and leads to Asgard. It curved out and down straight through the top of the highest pile of carven cylinders and then—it vanished through it. It was appalling—-it was demoniac—”
The crawling man stopped. His eyes rolled up into his head. He trembled and again his arms and legs began their horrible crawling movement. From his lips came a whispering. It was an echo of the high murmuring we had heard the night he came to us. I put my hands over his eyes. He quieted.
“The things accursed!” he said. “The People of the Pit ! Did I whisper? Yes—but they can't get me now—they can't!”
After a time he began as quietly as before.
“I crossed that span. I went down through the top of that—building. Blue darkness shrouded me for a moment and I felt the steps twist into a spiral. I wound down and then I was standing high up in—I can't tell you what. I'll have to call it a room. We have no images for what is in the pit. A hundred feet below me was the floor. The walls sloped down and out from where I stood in a series of widening crescents. The place was colossal—and it was filled with a curious mottled red light. It was like the light inside a green and gold-flecked fire opal. The spiral stairs wound below me. I went down to the last step. Far in front of me rose a high columned altar. Its pillars were carved in monstrous scrolls—like mad octopuses with a thousand drunken tentacles; they rested on the backs of shapeless monstrosities carved in crimson stone. The altar front was a gigantic slab of purple covered with carvings.
“I can't describe these carvings! No human being could—the human eye cannot grasp them any more than it can grasp shapes that haunt the fourth dimension. Only a subtle sense in the back of the brain grasped them vaguely. They were formless things that gave no conscious image, yet pressed into the mind like small hot seals—ideas of hate—of combat between unthinkable monstrous things—victories in a nebulous hell of steaming, obscene jungles—aspirations and ideals immeasurably loathsome—
“And as I stood I grew aware of something that lay behind the lip of the altar fifty feet above me. I knew it was there—I felt it with every hair and every tiny bit of my skin. Something infinitely malignant, infinitely horrible, infinitely ancient. It lurked, it brooded, it saw me, it threatened and it—was invisible!
“Behind me was a circle of blue light. Something urged me to turn back, to climb the stairs and make away. It was impossible. Terror of that unseen watching thing behind the altar raced
