the cliffs even as he was half across the valley. Flowers were burnt into effigies, grasses sucked back into rocks like singed snakes, flower seeds whirled and fell in the sudden furnace blast of wind, sown far into gullies and crannies, ready to blossom at sunset tonight, and then go to seed and die again. Sim's father watched that child running, alone, out on the floor of the valley. He and his wife and Dark and Sim were safe in the mouth of their tunnel. "He'll never make it," said father. "Do not watch him, woman. It's not a good thing to watch." They turned away. All except Sim, whose eyes had caught a glint of metal far away. His heart hammered in him, and his eyes blurred.

Sim fought to keep his parents young. But no matter how hard he fought with mind and image, they became like mummies before him. His father seemed to dissolve from one stage of oldness to another. This is what will happen to me soon, though Sim in terror. Sim grew upon himself. He felt the digestive-eliminatory movements of his body. He was fed every minute, he was continually swallowing,
