By-and-bye the man notices that no more half-eaten fish are on his side of the river. Little tracks of webbed feet furrowing a deep rut in the soft snow of the frozen river tell that nekik has taken alarm and is fishing from the other side. And when Christmas comes with a dwindling of the mink-hunt, the man, too, crosses to the other side. Here he finds that the otter tracks have worn a path that is almost a toboggan slide down the crusted snow bank to the iced edge of the pool. By this time nekik's pelt is prime, almost black, and as glossy as floss. By this time, too, the fish are scarce and the epicure has become ravenous as a pauper. One night when the trapper was reconnoitring the fish hole, he had approached the snow bank so noiselessly that he came on a whole colony of otters without their knowledge of his presence. Down the snow bank they tumbled, head-first, tail-first, slithering through the snow with their little paws braced, rolling down on their backs like lads upset from a toboggan, otter after otter, till the man learned that the little beasts were not fishing at all, but coasting the snow bank like youngsters on a night frolic. No sooner did one reach the bottom than up he scampered to repeat the fun; and sometimes two or three went down in a rolling bunch mixed up at the foot of a slide as badly as a couple of toboggans that were unpremeditatedly changing their occupants. Bears wrestle. The kittens of all the cat tribe play hide and seek. Little badger finds it fun to run round rubbing the back of his head on things; and here was nekik the otter at the favourite amusement of his kind--coasting down a snow bank. If the trapper were an Indian, he would lie in wait at the landing-place and spear the otter as they came from the water. But the white man's craft is deeper. He does not wish to frighten the otter till the last had been taken. Coming to the slide by day, he baits a steel-trap with fish and buries it in the snow just where the otter will be coming down the hill or up from the pool. Perhaps he places a dozen such traps around the hole with nothing visible but the frozen fish lying on the surface. If he sets his traps during a snow-fall, so much the better. His own tracks will be obliterated and the otter's nose will discover the fish. Then he takes a bag filled with some substance of animal odour, pomatum, fresh meat, pork, or he may use the flesh side of a fresh deer-hide. This he drags over the snow where he has stepped. He may even use a fresh hide to handle the traps, as a waiter uses a serviette to pass plates. There must be no man-smell, no man-track near the otter traps.
