The trees astonished him. They towered above him, fully five times as high as any he had ever seen. Their stems were of enormous girth--rough and hard to the touch. There seemed to be something moving in their heavy foliage, far above him, and he heard faint, sharp whistling sounds. He looked around uneasily. The size of the trees worried him. If there were animal life, it might be proportionately large. He shuddered. The desert, although uncomfortable, had had one advantage: he had been alone there. Still, it was not loneliness that he was seeking, he thought grimly. Obviously, he.... He stiffened. He had been staring abstractedly at the coarse grass which grew thickly around him. Now his eyes became focussed upon a movement there--not three feet away. The grass was waving strangely, in a peculiar, uneven line; and he caught sight of something slim and green, that was not the grass. His throat contracted painfully. The thing did not seem to move, yet it was coming nearer. Whenever he caught sight of a part of its body, it appeared stationary; yet the waving of the grass was closer, and ever closer. It was very close now.... Suddenly his power of locomotion returned. He rolled over backward, and scrambled along the ground to a tree. Grasping the rough trunk, he pulled himself erect; and held himself in that position, panting. He could see the thing more plainly now. It was like a long, green whip in the grass. Its forepart was raised in the air, and terminated in a triangular head, with two bright eyes whose steady, unwinking stare made him tremble weakly. With an effort he took his eyes from the creature; and, pushing himself away from the tree, ran desperately, as far as his legs would carry him. When he fell, he continued to crawl--farther, and ever farther into the green woods. He wondered if all creatures crawled in this world of Toon. Perhaps the great gravitational pull made erect postures impossible. For a long time he climbed steadily, threading his way through the underbrush, skirting fallen trees. He felt increasingly drowsy. His sleep period would come soon, he knew. He could not stave it off much longer. And when he had slept, he must eat.... He came to level ground. Ahead was an opening in the trees, where a wide ledge of stone was revealed. Out upon this he crawled, and gazed at the scene that opened out below. Miles of waving tree tops met his view; but what held his attention was a strip of silver cutting the green. He felt a warm glow of satisfaction. Water, in his mind, was closely associated with organization, transportation facilities, reasoning beings.... Yet he must be wary. He had no idea what sort of beings they might be. This might be a canal, but it was strangely irregular in its course. At least he was making progress....
