While he was there, his attention was attracted by a dipper flying across the water and, presently, he saw that on a little shelf of rock, almost directly below the falls, the bird had a nest formed of green moss. There was a little hole in the bundle of moss, at the mouth of which the bird alighted and seemed to pass in food. No doubt his mate was sitting on her eggs, which a little later would hatch into hungry young, to satisfy whose appetites would tax the efforts of both parents, no matter how hard they might work.
But Jack was hungry for fish and soon started down the stream. At first it was so overgrown by willows and spruces that he could not fish, but not far beyond this the trees stood farther back from it and he began to cast. Before he had gone far he had a rise and caught a nice ten-inch trout. Just below was a dark pool, from which he took four large fish, the largest weighing perhaps two pounds. His third fish was different from any of those he had taken before, and so was the fourth. Instead of being spotted with black, these two had red spots on them and heads larger and more clumsy than the black-spotted trout. They were not like the brook trout of the East and Jack was puzzled to know what they were, but felt sure that Hugh would tell him.
Keeping on down stream, he soon had ten fish strung on a willow twig, and the load was so heavy that he turned from the river and, passing through a fringe of timber, found himself near camp.
Joe was sitting not far from the fire half in the smoke, and was rubbing a lot of green leaves between his palms and then passing his hands over his face, neck and arms. Hugh, not so near the fire, was smoking vigorously, but seemed to be little troubled by the mosquitoes. The horses were still standing together, crowded into the smoke.
"Well, son," said Hugh, "that's a nice string of fish you've got. You've done well. That ought to last us for a couple of meals. Did you find the fish plenty?"
"Yes," replied Jack, "there are lots of them, and I want to ask you some questions about them. In the first place that pool right under the falls there is just full of fish, and yet not one of them would rise to my flies. I looked at them pretty carefully and I don't believe they're trout. Do you know what they are?"
