The shadows had grown long, with a suggestion of coming night; and other ears than mine had heard the sounds with interest. A swifter shadow fell on the water, and I looked up quickly to see a big owl sail silently out from the opposite hill and perch on a blasted stub overlooking the pool. Kookooskoos had been sleeping in a dark spruce when the sounds waked him, and he started out instantly, not to hunt--it was still too bright--but to locate his game and follow silently to the roosting place, near which he would hide and wait till the twilight fell darkly. I could see it all in his attitude as he poised forward, swinging his round head to and fro, like a dog on an air trail, locating the flock accurately before he should take another flight.
Up on the hillside the eager sounds had stopped for a moment, as if some strange sixth sense had warned the birds to be silent. The owl was puzzled; but I dared not move, because he was looking straight over me. Some faint sound, too faint for my ears, made him turn his head, and on the instant I reached for the tiny rifle lying before me in the canoe. Just as he spread his wings to investigate the new sound, the little rifle spoke, and he tumbled heavily to the shore.
"One robber the less," I was thinking, when the canoe swung slightly on the water. There was a heavy plunge, a vicious rush of my unheeded line, and I seized my rod to find myself fast to a big trout, which had been watching my flies from his hiding among the lily pads till his suspicions were quieted, and the first slight movement brought him up with a rush.
Ten minutes later he lay in my canoe, where I could see him plainly to my heart's content. I was waiting for the pool to grow quiet again, when a new sound came from the underbrush, a rapid _plop, lop, lop, lop, lop_, like the sound in a sunken bottle as water pours in and the air rushes out.
There was a brook near the sounds, a lazy little stream that had lost itself among the alders and forgotten all its music; and my first thought was that some animal was standing in the water to drink, and waking the voice of the brook as the current rippled past his legs. The canoe glided over to find out what he was, when, in the midst of the sounds, came the unmistakable _Whit-kwit?_ of partridges--and there they were, just vanishing glimpses of alert forms and keen eyes gliding among the tangled alder stems. When near the brook they had changed the soft, gossipy chatter, by which a flock holds itself together in the wild tangle of the burned lands, into a curious liquid sound, so like the gurgling of water by a mossy stone that it would have deceived me completely, had I not seen the birds. It was as if they tried to remind the little alder brook of the music it had lost far back among the hills.
