Presently we were arrested again by the proximity of a Selenite, and this time we were able to observe him more exactly. Now we could see that the Selenite covering was indeed clothing, and not a sort of crustacean integument. He was quite similar in his costume to the former one we had glimpsed, except that ends of something like wadding were protruding front his neck, and he stood on a promontory of rock and moved his head this way and that, as though he was surveying the crater. We lay quite still, fearing to attract his attention if we moved, and after a time he turned about and disappeared.
We came upon another drove of mooncalves bellowing up a ravine, and then we passed over a place of sounds, sounds of beating machinery as if some huge hall of industry came near the surface there. And while these sounds were still about us we came to the edge of a great open space, perhaps two hundred yards in diameter, and perfectly level. Save for a few lichens that advanced from its margin this space was bare, and presented a powdery surface of a dusty yellow colour. We were afraid to strike out across this space, but as it presented less obstruction to our crawling than the scrub, we went down upon it and began very circumspectly to skirt its edge.
For a little while the noises from below ceased and everything, save for the faint stir of the growing vegetation, was very still. Then abruptly there began an uproar, louder, more vehement, and nearer than any we had so far heard. Of a certainty it came from below. Instinctively we crouched as flat as we could, ready for a prompt plunge into the thicket beside us.
Each knock and throb seemed to vibrate through our bodies. Louder grew this throbbing and beating, and that irregular vibration increased until the whole moon world seemed to be jerking and pulsing.
"Cover," whispered Cavor, and I turned towards the bushes.
At that instant came a thud like the thud of a gun, and then a thing happened - it still haunts me in my dreams. I had turned my head to look at Cavor's face, and thrust out my hand in front of me as I so. And my hand met nothing! Plunged suddenly into a bottomless hole!
My chest hit something hard, and I found myself with my chin on the edge of an unfathomable abyss that had suddenly opened beneath me, my hand extended stiffly into the void. The whole of that flat circular area was no more than a gigantic lid, that was now sliding sideways from off the pit it had covered into a slot prepared for it.
Had it not been for Cavor I think I should have remained rigid, hanging over this margin and staring into the enormous gulf below, until at last the edges of the slot scraped me off and hurled me into its depths. But Cavor had not received the shock that had paralysed me. He had been a little distance from the edge when the lid had first opened, and perceiving the peril that held me helpless, gripped my legs and pulled me backward. I came into a sitting position, crawled away from the edge for a space on all fours, then staggered up and ran after him across the thundering, quivering sheet of metal. It seemed to be swinging open with a steadily accelerated velocity, and the bushes in front of me shifted sideways as I ran.
I was none too soon. Cavor's back vanished amidst the bristling thicket, and as I scrambled up after him, the monstrous valve came into its position with a clang. For a long time we lay panting, not daring to approach the pit.
But at last very cautiously and bit by bit we crept into a position from which we could peer down. The bushes about us creaked and waved with the force of a breeze that was blowing down the shaft. We could see nothing at first except smooth vertical walls descending at last into an impenetrable black. And then very gradually we became aware of a number of very faint and little lights going to and fro.
For a time that stupendous gulf of mystery held us so that we forgot even our sphere. In time, as we grew more accustomed to the darkness, we could make out very small, dim, elusive shapes moving about among those needle-point illuminations. We peered amazed and incredulous, understanding so little that we could find no words to say. We could distinguish nothing that would give us a clue to the meaning of the faint shapes we saw.
"What can it be?" I asked; "what can it be?"
"The engineering!... They must live in these caverns during the night, and come out during the day."
"Cavor! " I said. "Can they be - that - it was something like -, men?"
"That was not a man."
"We dare risk nothing"
"We dare do nothing until we find the sphere!"
"We can do nothing until we find the sphere."
He assented with a groan and stirred himself to move. He stared about him for a space, sighed, and indicated a direction. We struck out through the jungle. For a time we crawled resolutely, then with diminishing vigour.
Presently among great shapes of flabby purple there came a noise of trampling and cries about us. We lay close, and for a long time the sounds went to and fro and very near. But this time we saw nothing. I tried to whisper to Cavor that I could hardly go without food much longer, but my mouth had become too dry for whispering.
"Cavor," I said, "I must have food."
He turned a face full of dismay towards me. "It's a case for holding out," he said.
"But I must," I said, "and look at my lips!"
"I've been thirsty some time."
"If only some of that snow had remained!"
"It's clean gone! We're driving from arctic to tropical at the rate of a degree a minute. ..."
I gnawed my hand.
"The sphere!" he said. "There is nothing for it but the sphere."
