This simple act may have been the catalyst which gave Burl the solution to the problem. Some few days before, Burl had been in a far-away place where there was much food. At the time he'd thought vaguely of finding Saya and bringing her to that place. He remembered now that the red puffballs flourished there as well as here--but there had been other dangers in between, so the only half-formed purpose had been abandoned. Now, though, with Saya's head resting against his shoulder, he remembered the plan. And then the stroke of genius took place. He formed the idea of a journey which was not a going-after-food. This present dwelling-place of the tribe had been free of red puffballs until only recently. There must be other places where there were no red puffballs. He would take Saya and his tribesmen to such a place. It was really genius. The people of Burl's tribe had no purposes, only needs--for food and the like. Burl had achieved abstract thought--which previously had not been useful on the forgotten planet and, therefore, not practised. But it was time for humankind to take a more fitting place in the unbalanced ecological system of this nightmare world, time to change that unbalance in favor of humans. When dawn came, Burl had not slept at all. He was all authority and decision. He had made plans. He spoke sternly, loudly--which frightened people conditioned to be furtive--holding up his spear as he issued commands. His timid tribesfolk obeyed him meekly. They felt no loyalty to him or confidence in his decisions yet, but they were beginning to associate obedience to him with good things. Food, for one. Before the day fully came, they made loads of the remaining edible mushroom and uneaten meat. It was remarkable for humans to leave their hiding-place while they still had food to eat, but Burl was implacable and scowling. Three men bore spears at Burl's urging. He brandished his long shaft confidently as he persuaded the other three to carry clubs. They did so reluctantly, even though previously they had killed ants with clubs. Spears, they felt, would have been better. They wouldn't be so close to the prey then. The sky became gray over all its expanse. The indefinite bright area which marked the position of the sun became established. It was part-way toward the center of the sky when the journey began. Burl had, of course, no determined course, only a destination--safety. He had been carried south, in his misadventure on the river. There were red puffballs to southward, therefore he ruled out that direction. He could have chosen the east and come upon an ocean, but no safety from the red spore-dust. Or he could have chosen the north. It was pure chance that he headed west.
