The old man looked surprised, then he laughed as at a little joke on himself. "That's right--I won't see you again, will I? Good-bye, then." And they shook hands. They went out, Chion, Sim, and Lyte, together, followed by the others, all children growing swiftly into fighting men. And the light in Chion's eyes was not a good thing to see. * * * * * Lyte went with him. She chose his rocks for him and carried them. She would not go back, no matter how he pleaded. The sun was just beyond the horizon and they marched across the valley. "Please, Lyte, go back!" "And wait for Chion to return?" she said. "He plans that when you die I will be his mate." She shook out her unbelievable blue-white curls of hair defiantly. "But I'll be with you. If you fall, I fall." Sim's face hardened. He was tall. The world had shrunk during the night. Children packs screamed by hilarious in their food-searching and he looked at them with alien wonder: could it be only four days ago he'd been like these? Strange. There was a sense of many days in his mind, as if he'd really lived a thousand days. There was a dimension of incident and thought so thick, so multi-colored, so richly diverse in his head that it was not to be believed so much could happen in so short a time. The fighting men ran in clusters of two or three. Sim looked ahead at the rising line of small ebon cliffs. This, then, he said to himself, is my fourth day. And still I am no closer to the Ship, or to anything, not even--he heard the light tread of Lyte beside him--not even to her who bears my weapons and picks me ripe berries. One-half of his life was gone. Or a third of it--IF he won this battle. _If._ He ran easily, lifting, letting fall his legs. This is the day of my physical awareness, as I run I feed, as I feed I grow and as I grow I turn eyes to Lyte with a kind of dizzying vertigo. And she looks upon me with the same gentleness of thought. This is the day of our youth. Are we wasting it? Are we losing it on a dream, a folly? Distantly he heard laughter. As a child he'd questioned it. Now he understood laughter. This particular laughter was made of climbing high rocks and plucking the greenest blades and drinking the headiest vintage from the morning ices and eating of the rock-fruits and tasting of young lips in new appetite. They neared the cliffs of the enemy. He saw the slender erectness of Lyte. The new surprise of her white breasts; the neck where if you touched you could time her pulse; the fingers which cupped in your own were animate and supple and never still; the.... Lyte snapped her head to one side. "Look ahead!" she cried. "See what is to come--look only ahead." He felt that they were racing by part of their lives, leaving their youth on the pathside, without so much as a glance. "I am blind with looking at stones," he said, running. "Find new stones, then!"
