Pepe bent to the oars, and under his powerful strokes the boat glided up-stream. Soon the bridge disappeared. Ken had expected a long, shady ride, but it did not turn out so. Shallow water and gravelly rapids made rowing impossible. “Pile out, boys, and pull,” said Ken. The boys had dressed for wading and rough work, and went overboard with a will. Pulling, at first, was not hard work. They were fresh and eager, and hauled the boat up swift, shallow channels, making nearly as good time as when rowing in smooth water. Then, as the sun began to get hot, splashing in the cool river was pleasant. They passed little islands green with willows and came to high clay-banks gradually wearing away, and then met with rocky restrictions in the stream-bed. From round a bend came a hollow roar of a deeper rapid. Ken found it a swift-rushing incline, very narrow, and hard to pull along. The margin of the river was hidden and obstructed by willows so that the boys could see very little ahead. When they got above this fall the water was deep and still. Entering the boat again, they turned a curve into a long, beautiful stretch of river. “Ah! this ’s something like,” said Hal. The green, shady lane was alive with birds and water-fowl. Ducks of various kinds rose before the boat. White, blue, gray, and speckled herons, some six feet tall, lined the low bars, and flew only at near approach. There were many varieties of bitterns, one kind with a purple back and white breast. They were very tame and sat on the overhanging branches, uttering dismal croaks. Everywhere was the flash and glitter and gleam of birds in flight, up and down and across the river. Hal took his camera and tried to get pictures. The strangeness, beauty, and life of this jungle stream absorbed Ken. He did not take his guns from their cases. The water was bright green and very deep; here and there were the swirls of playing fish. The banks were high and densely covered with a luxuriant foliage. Huge cypress-trees, moss-covered, leaned half-way across the river. Giant gray-barked ceibas spread long branches thickly tufted with aloes, orchids, and other jungle parasites. Palm-trees lifted slender stems and graceful broad-leaved heads. Clumps of bamboo spread an enormous green arch out over the banks. These bamboo-trees were particularly beautiful to Ken. A hundred yellow, black-circled stems grew out of the ground close together, and as they rose high they gracefully leaned their bodies and drooped their tips. The leaves were arrowy, exquisite in their fineness. He looked up the long river-lane, bright in the sun, dark and still under the moss-veiled cypresses, at the turning vines and blossoming creepers, at the changeful web of moving birds, and indulged to the fullest that haunting sense for wild places. “Chicalocki,” said Pepe, suddenly.
