He had gained the middle of the estuary, when he saw arrowy gleams glance before him. Like hissing hail, a shower of darts struck the water. Then it seemed that gaudy butterflies floated about his face. Diving deep, he swam until compelled to rise for breath. As he came up, a crocodile rolled menacingly near. Manuel hit it a blow with his fist, and dove again. The coat hindered rapid swimming under water. He rose again to hear the crocodile swirling behind him. Darts splashed big drops on his cheeks, tugged at his head covering, streaked beyond him to skitter along the surface of the estuary. Reaching shallow water, he crawled into the reeds. White-mouthed snakes struck at him. The bank was low and overhung with rank growths. Manuel scrambled through to the solid ground; and then turned to have a look at his pursuers. Up and down the sandy beach a hundred or more Cashibos were running. How wild they were, how springy and fleet! How similar to the hungry, whirling sand flies! For a moment the disturbed caymans threshed about in the estuary, holding the cannibals back. Presently several of the most daring waded in above the commotion; then others entered below. Manuel breasted the dense jungle. Before him rose an apparently impenetrable wall of green. He dove into it, tore through it, leaving a trail of broken branches, twisted vines, and turned leaves. In places he ran encumbered by clinging creepers; in others he parted the thick growths with his hands and leaped high to separate them. Again he bent low to crawl along the peccary trails. Despite the obstacles, he went so swiftly that the jungle pests could not get at him; the few which did could not keep their hold, because of the scraping brush. Soon he ran out of a vine-webbed canebrake into a grove of sitekas, rubber trees, and palms. At every bound he sank into the moist earth, still he kept on running. He heard a scattering of animals before him, and saw a blur of flapping birds. The day seemed to darken. He looked up to see trees branching at a height of two hundred feet, and intermingling their foliage to obscure sun and sky. Here was the dim shade of the great forest of the Amazon tributaries. Sheering off to the right, he ran until the clinging earth clogged his feet. The forest was like a huge, dim hall full of humming life. Lines of shrieking monkeys hung on the ropelike vines that reached from the ground to green canopy overhead. Birds of paradise sailed like showers of gold through the thick, hazy air. Before him fled boas, peccaries, ant-eaters, spotted cats, and beasts that he could not name.
