If Ken had looked again or hesitated a moment he would have lost his nerve. He recognized that fact. And he shoved off instantly. Once the boat had begun to glide down, gathering momentum, he felt his teeth grind hard and his muscles grow tense. He had to bend his head from side to side to see beyond the canvas George and Hal were holding round their shoulders. He believed with that acting as a buffer in the stern he could go pounding through those waves. Then he was in the middle of the channel, and the boat fairly sailed along. Ken kept his oars poised, ready to drop either one for a stroke. All he wanted was to enter those foaming, tumultuous waves with his boat pointed right. He knew he could not hope to see anything low down after he entered the race. He calculated that the last instant would give him an opportunity to get his direction in line with some object. Then, even as he planned it, the boat dipped on a beautiful glassy incline, and glided down toward the engulfing, roaring waves. Above them, just in the center, Ken caught sight of the tufted top of a palm-tree. That was his landmark! The boat shot into a great, curling, back-lashing wave. There was a heavy shock, a pause, and then Ken felt himself lifted high, while a huge sheet of water rose fan-shape behind the buffer in the stern. Walls and sky and tree faded under a watery curtain. Then the boat shot on again; the light came, the sky shone, and Ken saw his palm-tree. He pulled hard on the right oar to get the stern back in line. Another heavy shock, a pause, a blinding shower of water, and then the downward rush! Ken got a fleeting glimpse of his guiding mark, and sunk the left oar deep for a strong stroke. The beating of the waves upon the upraised oars almost threw him out of the boat. The wrestling waters hissed and bellowed. Down the boat shot and up, to pound and pound, and then again shoot down. Through the pall of mist and spray Ken always got a glimpse, quick as lightning, of the palm-tree, and like a demon he plunged in his oars to keep the boat in line. He was only dimly conscious of the awfulness of the place. But he was not afraid. He felt his action as being inspirited by something grim and determined. He was fighting the river. All at once a grating jar behind told him the bow had hit a stone or a wall. He did not dare look back. The most fleeting instant of time might be the one for him to see his guiding mark. Then the boat lurched under him, lifted high with bow up, and lightened. He knew Pepe had been pitched overboard.
