The winter had been dry and cold. The few otters recently seen by daylight were hunting over the snow for grouse and rabbits, far from the stream. Otter food was scarce. Probably many, possibly all, of these merrymakers were hungry, but little would you have guessed it from their play. It was a merry-go-round of coasters climbing up single file by the slide while coaster after coaster shot singly down. Each appeared to start with a head-foremost vault or dive and to dart downward over the slides with all legs flattened and pointing backward. Each coaster, as a rule, shot straight to the bottom, though a few times one went off at an angle and finished with a roll. A successful slide carried the coaster far out on the smooth ice and occasionally to the farther bank of the river. After half an hour of coasting all collected at the top of the slide for wrestling contests. A number dodged about, touching, tagging, rearing to clinch and then to roll over. Several exhibitions were occurring at one time. A few times one chased another several yards from the crowd. Once a number stood up in pairs with forepaws on each other’s shoulders and appeared to be waltzing. Finally there was a free-for-all mix-up, a grand rush. One appeared to have an object, perhaps a cone, which all the others were after. Then, as if by common consent, all plunged down the slide together. At the bottom they rolled about for a few seconds in merry satisfaction, but only for a few seconds, for soon several climbed up again and came coasting down in pairs. Thus for an hour the play in the frosty moonlight went on, and without cry or uttered sound. They were coasting singly when I slipped away to my campfire. The otter is one of the greatest of travellers. He swims the streams for miles or makes long journeys into the hills. On land he usually selects the smoothest, easiest way, but once I saw him descend a rocky precipice with speed and skill excelled only by the bighorn sheep. He has a permanent home range and generally this is large. From his den beneath the roots of a tree, near a stream bank or lake shore, he may go twenty miles up or down stream; or he may traverse the woods to a far-off lake or cross the watershed to the next stream, miles away. He appears to emigrate sometimes--goes to live in other scenes. These long journeys for food or adventure, sometimes covering weeks, must fill the otter’s life with colour and excitement. Swimming miles down a deep watercourse may require only an hour or two. But a journey up stream often to its very source, through cascades and scant water, would often force the travellers out of the channel and offer endless opportunities for slow progress and unexpected happenings. What an experience for the youngsters!
