“The fur consists of an exceedingly thick, flaky, woolly coat of silky softness and a thin, long outer coat composed of strong, stiff, shining hair, short on the head and rear part of the back and over two inches long on the rest of the body.” The tail, which is rounded at the base, much flattened and very broad, bears horny, dark-colored scales. The fore legs are short and the feet are unwebbed. The hind legs are much stronger, the feet are fully webbed and they, alone, are used, with the aid of the tail, to propel the Beaver through the water. In the water it is graceful in its motions, but on the land, like nearly all animals that are fitted for a partially aquatic life, it is clumsy and awkward and its motions are neither rapid nor uniform. [Illustration: ] Usually it is only in those districts that are remote from the habitations of man that the Beaver lives in colonies, consisting of several families, and builds its “lodges.” Nearer civilization it lives in burrows or tunnels. In the building of their homes, as well as in the storing of a supply of food, the female is the most active and is the practical builder, while the male assists. Brehm writes interestingly regarding the Beaver. He says: “After mature deliberation the animals select a stream or pool, the banks of which afford them ample provender and seem specially adapted for the construction of their ‘lodges.’ Those which live singly dwell in simple subterranean burrows, after the manner of otters; societies, which generally consist of families, as a rule construct houses and, if there should be a necessity for it, dams, in order to hold back the water and preserve it at a uniform height. Some of these dams are from four hundred and fifty to six hundred feet long, from six to nine feet high, from twelve to eighteen feet thick at the base and from three to six feet at the top. They consist of logs varying in size from the thickness of an arm to that of a thigh and from three to six feet long. One end of the log or stake is thrust in the ground, the other stands upright in the water; the logs are fastened together by means of thin twigs and made tight with reeds, mud and earth, in such a way that one side presents a nearly vertical, firm wall to the stream, while the other side is sloped. From the ponds rising above the dams, canals are constructed to facilitate the carrying or floating of the necessary construction materials and food. Beavers do not forsake a settlement they have founded unless the direst necessity compels them to do so. Beavers’ lodges, the origin of which dates very far back, are often found in lonely woods.”
