Sick with despair he felt his way back to the body and sat down. The truth was now beyond doubt. There was no good waiting for the morning. There would be no morning here till the end of the world, and perhaps he had already waited a night and a day. The clanging echoes, the dead air, the very smell of the place, all confirmed this. He and his enemy when they sank had clearly, by some hundredth chance, been carried through a hole in the cliffs well below water-level and come up on the beach of a cavern. Was it possible to reverse the process? He went down to the water’s edge-or rather. as he groped his way down to where the shingle was wet, the water came to meet him. It thundered over his head and far up behind him, and then receded with a tug which he only resisted by spread-eagling himself on the beach and gripping the stones. It would be useless to plunge into that-he would merely have his ribs broken against the opposite wall of the cave. If one load light, and a high place to dive from, it was just conceivable one might get down to the bottom and strike the exit . . . but very doubtful. And anyway, one had no light.
Although the air was not very good he supposed that his prison must be supplied with air from somewhere-but whether from any aperture that he could possibly reach was another matter. He turned at once and began exploring the rock behind the beach. At first it seemed hopeless, but the conviction that caves may lead you anywhere dies hard, and after some time his groping hands found a shelf about three feet high. He stepped up on it. He had expected it to be only a few inches deep but his hands could find no wall before him. Very cautiously he took some paces forward. His right foot touched something sharp. He whistled with the pain and went on even more cautiously. Then he found vertical rock, smooth as high as he could reach. He turned to his right and presently lost it. He turned left and began to go forward again and almost at once stubbed his toe. After nursing it for a moment he went down on hands and knees. He seemed to be among boulders, but the way was practicable. For ten minutes or so he made fairly good going, pretty steeply upward, sometimes on slippery shingle, sometimes over the tops of the big stones. Then he came to another cliff. There appeared to be a shelf on this about four feet up, but this time a really shallow one. He got on to it somehow and glued himself to the face, feeling out to left and right for further grips.
When he found one and realised that he was now about to attempt some real climbing, he hesitated. He remembered that what was above him might be a cliff which even in daylight and properly clothed he would never dare to attempt: but hope whispered that it might equally well be only seven feet high and that a few minutes of coolness might bring him into those gently winding passages up into the heart of the mountain which had, by now, won such a firm place in his imagination. He decided to go on. What worried him was not, in fact, the fear of falling, but the fear of cutting himself off from the water. Starvation he thought he could face: not thirst. But he went on. For some minutes he did things which he had never done on Earth. Doubtless he was in one way helped by the darkness: he had no real sensation of height and no giddiness. On the other hand, to work by touch alone made crazy climbing. Doubtless if anyone had seen him he would have appeared at one moment to take mad risks and at another to indulge in excessive caution. He tried to keep out of his mind the possibility that he might be climbing merely towards a roof.
After about quarter of an hour he found himself on a wide horizontal surface-either a much deeper shelf or the top of the, precipice. He rested here for a while and licked his cuts. Then he got up and felt his way forwards, expecting every moment to meet another rock wall. When, after about thirty paces, he had not done so, he tried shouting and judged from the sound that he was in a fairly open place. Then he continued. The floor was of small pebble and ascended fairly steeply. There were some larger stones but he had learned to curl up his toes as his foot felt for the next place and he seldom stubbed them now. One minor trouble was that even in this perfect blackness he could not help straining his eyes to see. It gave him a headache and created phantom lights and colours.
This slow uphill trek through darkness lasted so long that he began to fear he was going round in a circle, or that he had blundered into some gallery which ran on for ever beneath the surface of the planet. The steady ascent in some degree reassured him. The starvation for light became very painful. He found himself thinking about light as a hungry man thinks about food-picturing April hillsides with milky clouds racing over them in blue skies or quiet circles of lamplight on tables pleasantly littered with books and pipes. By a curious confusion of mind he found it impossible not to imagine that the slope he walked on was not merely dark, but black in its own right, as if with soot. He felt that his feet and hands must be blackened by touching it. Whenever he pictured himself arriving at any light, he also pictured that light revealing a world of soot all around him.
He struck his head sharply against something and sat down half stunned. When he had collected himself he found by groping that the shingle slope had run up into a roof of smooth rock. His heart was very low as he sat there digesting this discovery. The sound of the waves came up faint and melancholy from below and told him that he was now at a great height. At last, though with very little hope, he began walking to his right, keeping contact with the roof by raising his arms. Presently it receded beyond his reach. A long time after that he heard a sound of water. He went on more slowly in great fear of encountering a waterfall. The shingle began to be wet and finally he stood in a little pool. Turning to his left he found, indeed, a waterfall, but it was a tiny stream with no force of water that could endanger him. He knelt in the rippling pool and drank from the fall and put his aching head and weary shoulders under it. Then, greatly refreshed, he tried to work his way up it.
Though the stones were slippery with some kind of moss and many of the pools were deep, it presented no serious difficulties. In about twenty minutes he had reached the top, and as far as he could judge by shouting and noticing the echo he was now in a very large cave indeed. He took the stream for guidance and proceeded to follow it up. In that featureless dark it was some sort of company. Some real hope-distinct from that mere convention of hope which supports men in desperate situations-began to enter his mind.
It was shortly after this that he began to be worried by the noises. The last faint booming of the sea in the little hole whence he had set out so many hours ago had now died away and the predominant sound was the gentle tinkling of the stream. But he now began to think that he heard other noises mixed with it. Sometimes it would be a dull plump as if something had slipped into one of the pools behind him: sometimes, more mysteriously, a dry rattling sound as if metal were being dragged over the stones. At first he put it down to imagination. Then he stopped once or twice to listen and heard nothing but each time when he went on it began again. At last, stopping once more, he heard it quite unmistakably. Could it be that the Un-man had after all come to life and was still following him? But that seemed improbable, for its whole plan had been to escape. It was not so easy to dispose of the other possibility-that these caverns might have inhabitants. All his experience, indeed, assured him that if there were such inhabitants they would probably be harmless, but somehow he could not quite believe that anything which lived in such a place would be agreeable, and a little echo of the Un-man’s-or was it Weston’s-talk came back to him. “All beautiful on the surface, but down inside-darkness, heat, horror, and stink.” Then it occurred to him that if some creature were following him up the stream it might be well for him to leave its banks and wait till the creature had gone past. But if it were hunting him it would presumably hunt by scent; and in any case he would not risk losing the stream. In the end he went on.
