lip. It came again, touched experimentally, vanished. He swallowed. His eyes opened wider and he paid no attention to the jab. He began to breathe quickly. “Water!” As in the sea at a moment of desperate crisis his body changed, became able and willing. He scrambled out of the trench on legs that were no longer wooden. He climbed across fallen buttresses that had never supported anything but their own weight; he slithered in the white pools of the trenches near the top of the rock. He came to the edge of the cliff where he had climbed and a solitary gull slipped away from under his feet. He worked himself round on his two feet but the horizon was like itself at every point. He could only tell when he had inspected every point by the lie of the rock beneath him. He went round again. At last he turned back to the rock itself and climbed down but more slowly now from trench to trench. When he was below the level of the white bird-droppings he stopped and began to examine the rock foot by foot. He crouched in a trench, gripping the lower side and looking at every part of it with quick glances as if he were trying to follow the flight of a hover-fly. He saw water on a flat rock, went to it, put his hands on either side of the puddle and stuck his tongue in. His lips contracted down round his tongue, sucked. The puddle became nothing but a patch of wetness on the rock. He crawled on. He came to a horizontal crack in the side of a trench. Beneath the crack a slab of rock was falling away and there was water caught. He put his forehead against the rock then turned sideways until his cheek rested above the crack—but still his tongue could not reach the water. He thrust and thrust, mouth ground against the stone but still the water was beyond him. He seized the cracked stone and jerked furiously until it broke away. The water spilled down and became a film in the bottom of the trench. He stood there, heart thumping and held the broken stone in his hands. “Use you loaf, man. Use your loaf.” He looked down the jumbled slope before him. He began to work the rock methodically. He noticed the broken stone in his hands and dropped it. He worked across the rock and back from trench to trench. He came on the mouldering bones of fish and a dead gull, its upturned breast-bone like the keel of a derelict boat. He found patches of grey and yellow lichen, traces even of earth, a button of moss. There were the empty shells of crabs, pieces of dead weed, and the claws of a lobster. At the lower end of the rock there were pools of water but they were salt. He came back up the slope, his needle and the fires forgotten. He groped in the crevice where he had lain all night but the rock was nearly dry. He clambered over the fallen slab of stone that had sheltered him. The slab was in two pieces. Once there must have been a huge upended layer of rock that had endured while the others weathered away. It had fallen and broken in two. The larger piece lay across the trench at the very edge of the rock. Part of it projected over the sea, and the trench led underneath like a gutter. He lay down and inserted himself. He paused. Then he was jerking his tail like a seal and lifting himself forward with his flippers. He put his head down and made sucking noises. Then he lay still. The place in which he had found water was like a little cave. The floor of the trench sloped down gently under water so that this end of the pool was shallow. There was room for him to lie with his elbows spread apart for the slab had smashed down the wall on the right-hand side. The roof stone lay across at an angle and the farther end of the cave was not entirely stopped up. There was a small hole high up by the roof, full of daylight and a patch of sky. The light from the sky was reflected in and from the water so that faint lines quivered over the stone roof. The water was drinkable but there was no pleasure in the taste. It tasted of things that were vaguely
