He bobbed himself up and down as he perched on the root in the oddest manner, bending his legs so that his body almost touched his perch, and rising again quickly, this repeated in quick succession as if curtsying. This motion with him is a sign of uncertainty--it shows suspicion; after he had bobbed to me ten times, off he went. I found him next on a stone in the middle of the river; it stood up above the surface of a rapid connecting two pools. Like the trout, the colley always feeds at the rapids, and flies as they swim, from fall to fall. He was bobbing up and down, his legs bent, and his rusty brown body went up and down, but as I was hidden by a hedge he pained confidence, suspended his curtsying, and began to feed. First he looked all round the stone, and then stepped to another similar island in the midst of the rushing water, pushing his head over the edge into it. Next he stepped into the current, which, though shallow, looked strong enough to sweep him away. The water checked against him rose to the white mark on his breast. He waded up the rapid, every now and then thrusting his head completely under the water; sometimes he was up to his neck, sometimes not so deep; now and then getting on a stone, searching right and left as he climbed the cascade. The eddying water shot by his slender legs, but he moved against it easily, and soon ascended the waterfall. At the summit a second colley flew past, and he rose and accompanied his friend. Upon a ledge of rock I saw him once more, but there was no hedge to hide me, and he would not feed; he stood and curtsied, and at the moment of bobbing let his wings too partly down, his tail drooping at the same time. Calling in an injured tone, as if much annoyed, he flew, swept round the meadow, and so to the river behind me. His friend followed. On reaching the river at a safe distance down, he skimmed along the surface like a kingfisher. They find abundance of insect life among the stones at the falls, and everywhere in shallow water. Some accuse them of taking the ova of trout, and they are shot at trout nurseries; but it is doubtful if they are really guilty, nor can they do any appreciable injury in an open stream, not being in sufficient numbers. It is the birds and other creatures peculiar to the water that render fly-fishing so pleasant; were they all destroyed, and nothing left but the mere fish, one might as well stand and fish in a stone cattle-trough. I hope all true lovers of sport will assist in preserving rather than in killing them. NOTES ON LANDSCAPE PAINTING I
