search his parents' thoughts for knowledge. Because in a few hours they'd be dead. This was so impossibly unfair. Was this all of life? In his prenatal state hadn't he dreamed of long lives, valleys not of blasted stone but green foliage and temperate clime? Yes! And if he'd dreamed then there must be truth in the visions. How could he seek and find the long life? Where? And how could he accomplish a life mission that huge and depressing in eight short, vanishing days? How had his people gotten into such a condition? As if at a button pressed, he saw an image. Metal seeds, blown across space from a distant green world, fighting with long flames, crashing on this bleak planet. From their shattered hulls tumble men and women. When? Long ago. Ten thousand days. The crash victims hid in the cliffs from the sun. Fire, ice and floods washed away the wreckage of the huge metal seeds. The victims were shaped and beaten like iron upon a forge. Solar radiations drenched them. Their pulses quickened, two hundred, five hundred, a thousand beats a minute. Their skins thickened, their blood changed. Old age came rushing. Children were born in the caves. Swifter, swifter, swifter the process. Like all this world's wild life, the men and women from the crash lived and died in a week, leaving children to do likewise. So this is life, thought Sim.

So I'm the five thousandth in a long line of futile sons? What can I do to save myself from dying eight days from now? Is there escape? His eyes widened, another image came to focus. Beyond this valley of cliffs, on a low mountain lay a perfect, unscarred metal seed. A metal ship, not rusted or touched by the avalanches. The ship was deserted, whole, intact. It was the only ship of all these that had crashed that was still a unit, still usable. But it was so far away. There was no one in it to help. This ship, then, on the far mountain, was the destiny toward which he would grow. There was his only hope of escape. His mind flexed. In this cliff, deep down in a confinement of solitude, worked a handful of scientists. To these men, when he was old enough and wise enough, he must go. They, too, dreamed of escape, of
