The fish fought for three or four minutes, gleaming, a streak of silver, through the shadowy flood, as it showed its side, then sprang clear and changed again to a half-seen dusky shape that drove violently here and there. Then it came up toward the bending point of the rod, and at length Harry, slipping his hat beneath it, lifted it out. "Nearly three quarters of a pound," he said. "Your trace is clear now. Try again, and never mind about the slack and eddies. Pitch your flies anywhere." Frank did so, and they had scarcely fallen when there was a second rush, but this fish seemed smaller and he dragged it out unceremoniously upon the shingle. It was the same the next cast, and for a while he was kept desperately busy. When at length he laid the rod down Harry announced that they had a dozen fish. "We'll try the next pool now," he added. "Some of these trout aren't half a pound and I'd like you to get a real big one." The next pool proved to be some distance away and there was nothing but rock and foaming water between, but when they reached a slacker place where the current circled around a deep basin Frank had four or five more minutes' fishing, during which he landed several trout. Then the flies seemed to vanish and there was scarcely a splash on the shadowy water. "You may as well put the rod up," Harry advised. "It's a sure thing you won't get another." Frank tried for a few minutes, but finding his companion's prediction justified, sat down near him among the roots of a big fir. At the foot of the pool where he had been fishing the stream swept furiously between big scattered boulders in a wild white rapid. It was narrower there, and a ledge of rock, slightly hollowed out underneath, rose above it on the side on which they sat a little more than a hundred yards away. The woods were now darkening fast, and the chill of the dew was in the air, which was heavy with the scent of redwood and cedar. In places the water still glimmered faintly, and except for the roar it made, everything was very still. Suddenly Harry pointed to the dog, who was lying near Frank. "Get hold of him," he said in a low voice. "If nothing else will keep him quiet, we'll roll your jacket round his head." Frank, who had taken off his jacket, which was badly torn, when he began fishing, laid his hand on the dog as it arose with a low growl. Then as it tried to break away from him he seized its collar and held on with all his might while Harry flung the jacket over it. Though the thing cost them an effort they managed to hold the animal still between them. In the meanwhile there was a crackle of undergrowth and Frank saw a man who walked in a rather curious manner move out from the shadow. Even when he was clear of the overhanging branches it was impossible to see him distinctly, but Frank recognized him with a start. There was something wrong with one of the dark figure's shoulders.
