He was following a game trail. There were many of them; they crossed and crisscrossed all through the forest. Some of them must lead to water; but which ones? He had chosen the one he was following because it was broader and more plainly marked than the others. Many beasts had passed along it and, perhaps, for an incalculable time, for it was worn deep; and von Horst reasoned that more animals would follow a trail that led to water than would follow any other trail. He was right. When he came to a little river, he gave a cry of delight and ran to it and threw himself face down upon the bank. He drank in great gulps. Perhaps it should have harmed him, but it did not. It was a clean little river that ran among boulders over a gravelly bottom, a gem of a river that carried on its bosom to the forest and the lowlands the freshness and the coolness and the beauty of the mountains that gave it birth. Von Horst buried his face in the water, he let it purl over his bare arms, he cupped his hands and dipped it up and poured it over his head, he revelled in it. He felt that he had never known a luxury so rare, so desirable. His troubles vanished. Everything would be all right now—he had water! Now he was safe!

He looked up. Upon the opposite bank of the little river squatted such a creature as was never in any book, the bones of which were never in any museum. It resembled a gigantic winged kangaroo with the head of a reptile, pterodactyl-like in its long, heavily fanged jaws. It was watching von Horst intently, its cold, reptilian, lidless eyes staring at him expressionlessly. There was something terribly menacing in its fixed gaze. The man started to rise slowly; then the hideous thing came to sudden life.
