The otter does not travel much on land, except when crossing country from one lake or stream to another. Their bodies being long and their legs short, walking is, for them, rather difficult and their mode of locomotion is a series of plunging leaps. On the snow or ice they move along rapidly by throwing themselves forward, sliding on their bellies. They are very playful animals and sometimes amuse themselves by sliding down a slippery bank. They also have landing places where they go to roll in the leaves and grass. In the spring they often lay for hours on some old log by the side of the stream, basking in the warm sun. They can remain a long time under water, and in winter travel long distances under the ice,--in fact, they prefer to travel this way whenever possible. The home of the otter is a burrow in the bank of a stream, the entrance under water. At the end of the burrow is a nest lined with leaves and grass. They also, sometimes, den in hollow logs and the trunks of hollow trees. The dens are always located in the most secluded places, as far as possible removed from danger of discovery. The young are born in April or May and the number is from two to four. With regard to raising the beaver and otter for profit, we will say that there has been comparatively few attempts at the business and we are unable to get any authentic data with regard to these experiments. However, the animals do well in captivity, in zoos, and when kept by private individuals, as pets, and it is our opinion that if one will but go slowly and learn the habits and nature of the animals, a fair degree of success may be attained. It should be understood that conditions must be favorable and the animals should be given a range as nearly like their natural home as possible. Of course, one could not make a success of raising beavers in an open field. They must have wooded land where their natural food, quaking aspen (sometimes poplar), birch, willow, cottonwood, alder, is plentiful. A pool on some quiet little stream, bordered by a large tract of forest, would be the proper place. Beavers are not given to roaming, except during the summer months, and in such cases they always return to their home before cold weather comes. We believe that the animals could not be raised successfully by any of the plans recommended for the rearing of other fur-bearing animals, but should simply be placed in a large enclosure, in the proper location, and allowed to take care of themselves. The animals will breed perfectly without any attention and there will be no danger of them killing their offspring, as is the case with other fur bearers. There is no doubt that the beaver and the otter will do well in the same enclosure, for in the wild state they are very sociable and are fond of one another's company.
