"One thing I would like--to get at the one who set this trap," commented Vye. Hume laughed with dry humor. "After me, boy, after me. But I think we might have to wait a long time for that meeting." 10 Vye crawled weakly from the area of a rock outcrop. The sun, reflected from the cliff side, was a lash of fire across his emaciated body. His swollen tongue moved a pebble back and forth in his dry mouth. He stared dimly down the slope to that beckoning platter of water open under the sun, rimmed with the deadly woodland. What had happened? They had gone to sleep that first night under the ledge of the dried waterfall. And all of the next day was only a haze to him now. They must have moved on, though he could remember nothing, save Hume's odd behavior--dull-eyed silence while stumbling on as a brainless servio-robot, incoherent speech wherein all the words came fast, running together unintelligibly. And for himself--patches of blackout. At some time they had come to the cave and Hume had collapsed, not rousing in answer to any of Vye's struggles to awaken him. How long they had been there Vye could not tell now. He had the fear of being left alone in this place. With water perhaps Hume could be returned to consciousness, but that was all gone. Vye believed he could scent the lake, that every breeze up slope brought its compelling enticement. Just in case Hume might awake to a state of semi-consciousness and wander off, Vye tethered him with blanket bonds. Vye fingered Hume's knife, which had been painstakingly lashed to a trimmed shaft of wood. Since he had emerged from that clouding of mind which still gripped the Hunter, he had done what he could to prepare for another attack from any roving beast. And he also had Hume's ray tube--its single charge to be used only in dire need. Water! His cracked lips moved, ejected the pebble. Their four empty water bulbs were in the front of his blanket tunic, pressing against his ribs. It was now--or die, because soon he would be too weak to make the attempt at all. He darted for the first stand of bush downhill. As the brooding silence of the valley continued, he reached the edge of the wood unhindered, intent on his mission with a concentration which shut out everything save his need and the manner of satisfying it. He squatted in the bush, eyeing the length of woodland ahead. Then he tried the only action he had been able to think out. That beast Hume had killed had been too heavy to swing up in trees. But Vye's own weight now did not prohibit that form of travel. With spear and ray tube firmly attached to him, Vye climbed into the first tree. A slim chance--but his only defense against a possible ambush. A wild outward swing brought him, heart-thudding, to the next set of limbs. Then he had a piece of luck, a looped vine tied together a whole group of branches from one treetop to the next.
