the ledge and came back. At the lower end of the great rock he found the stones with the wrong shape and took them one by one to a trench and piled them. He pried in crevices and pulled out blocks and rounded masses of yellowing quartz on which the weed was draggled like green hair. He took them to the man he was building and piled them round the bottom stone. Some were not much bigger than potatoes and he knocked these in where the big stones did not fit until the top one no longer rocked when he touched it. He put one last stone on the others, one big as his head. Three feet. He stood away from the pile and looked round him. The pile reached in his view from horizon level to higher than the sun. He was astonished when he saw this and looked carefully to establish where west was. He saw the outlying rock that had saved him and the sea-gulls were floating just beyond the backwash. He climbed down the rock again to where he had prised off the limpet. He made a wry face and pushed his doubled fists into the damp cloth over his belly. He hung on the little cliff and began to tear away the blobs of red jelly with his fingers. He set them on the edge of the cliff and did not look at them for a while. Then he turned his one and a half eyes down to them and inspected them closely. They lay like a handful of sweets only they moved ever so slightly and there was a little clear water trickling from the pile. He sat by them on the edge of the cliff and no longer saw them. His face set in a look of agony. “Bloody hell!” His fingers closed over a sweet. He put it quickly in his mouth, ducked, swallowed, shuddered. He took another, swallowed, took another as fast as he could. He bolted the pile of sweets then sat rigid, his throat working. He subsided , grinning palely. He looked down at his left hand and there was one last sweet lying against his little finger in a drip of water. He clapped his hand to his mouth, stared over the fingers and fought with his stomach. He scrambled over the rocks to the water-hole and pulled himself in. Again the coils of red silt and slime rose from the bottom. There was a band of red round the nearer end of the pool that was about half an inch across. When he had settled his stomach with the harsh water he came out of the hole backwards. The sea-gulls were circling the rock now and he looked at them with hate. “You won’t get me!” He clambered back to the top of the rock where his three-foot dwarf stood. The horizon was in sight all round and empty. He licked a trace of drinkable water from his lips. “I have enough to drink——” He stood, looking down at the slab over his drinking water where it projected like a diving-board. He went slowly to the cliff, got down and peered under the slab. The seaward end of the pool was held back by a jumble of broken stones that were lodged against each other. Behind the impaired window of his sight he saw the red silt rising and coiling. The stuff must lie over the inner side of these stones, sealing them lightly against the water’s escape. He had a quick vision of the hidden surfaces, holes that time had furred with red till they were stopped and the incongruous fresh water held back among all the salt; but held back so delicately that the merest touch would set his life irrevocably flowing—— He backed away with staring eyes and breath that came quick. “Forget it!” He began to thrust himself backwards into the sleeping crevice. He got almost to his ears out of sight and filled the hole with his body and heavy clothing. He pulled the sleeves of his duffle out of the oilskin tubes until they came over the backs of his hands. After a little struggling he could grip them with his fingers and double his fists so that they were hidden in the hairy duffle. The lifebelt supported his chest and throat once more and he pillowed his left cheek on his forearm. He lay so, shivering now that the sun had gone down, while the green sky turned blue,
