After a long while those spaces of mental clarity grew longer, appearing closer together. He dug small shelled things from under stones along the river and ate them avidly. Once he clubbed a rabbit and feasted. He sucked birds' eggs from a nest hidden among some reeds—just enough to keep his gaunt body going, though his gray eyes were now set in what was almost a death's-head.
Ross did not know just when he realized that he was again being hunted. It started with an uneasiness which differed from his previous fever-bred hallucinations. This was an inner pulling, a growing compulsion to turn and retrace his way back toward the mountains to meet something, or someone, waiting for him on the backward path.
But Ross kept on, fearing sleep now and fighting it. For once he had lain down to rest and had wakened on his feet, heading back as if that compulsion had the power to take over his body when his waking will was off guard.
So he rested, but he dared not sleep, the desire constantly tearing at his will, striving to take over his weakened body and draw it back. Perhaps against all reason he believed that it was the aliens who were trying to control him. Ross did not even venture to guess why they were so determined to get him. If there were tribesmen on his trail as well, he did not know, but he was sure that this was now purely a war of wills.
As the banks of the river were giving way to marshes, he had to wade through mud and water, detouring the boggy sections. Great clouds of birds whirled and shrieked their protests at his coming, and sleek water animals paddled and poked curious heads out of the water as this two-legged thing walked mechanically through their green land. Always that pull was with him, until Ross was more aware of fighting it than of traveling.
Why did they want him to return? Why did they not follow him? Or were they afraid to venture too far from where they had come through the transfer? Yet the unseen rope which was tugging at him did not grow less tenuous as he put more distance between himself and the mountain valley. Ross could understand neither their motives nor their methods, but he could continue to fight.
The bog was endless. He found an island and lashed himself with his suit belt to the single willow which grew there, knowing that he must have sleep, or he could not hope to last through the next day. Then he slept, only to waken cold, shaking, and afraid. Shoulder deep in a pool, he was aware that in his sleep he must have opened the belt buckle and freed himself, and only the mishap of falling into the water had brought him around to sanity.
Somehow he got back to the tree, rehooked the buckle and twisted the belt around the branches so that he was sure he could not work it free until daybreak. He lapsed into a deepening doze, and awoke, still safely anchored, with the morning cries of the birds. Ross considered the suit as he untangled the belt. Could the strange clothing be the tie by which the aliens held to him? If he were to strip, leaving the garment behind, would he be safe?
He tried to force open the studs across his chest, but they would not yield to the slight pressure which was all his seared fingers could exert, and when he pulled at the fabric, he was unable to tear it. So, still wearing the livery of the off-world men, Ross continued on his way, hardly caring where he went or how. The mud plastered on him by his frequent falls was some protection against the swarm of insect life his passing stirred into attack. However, he was able to endure a swollen face and slitted eyes, being far more conscious of the wrenching feeling within him than the misery of his body.
The character of the marsh began to change once more. The river was splitting into a dozen smaller streams, shaping out fanlike. Looking down at this from one of the marsh hillocks, Ross knew a faint surge of relief. Such a place had been on the map Ashe had made them memorize. He was close to the sea at last, and for the moment that was enough.
