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."

The Beaver usually feeds upon the bark of the younger branches of trees and shrubs and upon their leaves. It will also strip the older branches, in a very skillful manner, and eat the inner tender portion of the bark. During the fall and early winter months they work constantly in preparing and storing, in the neighborhood of their lodges, the winters supply of food. "Each cabin has its own magazine, proportioned to the number of its inhabitants, who have all a common right to the store and never pillage their neighbors."

The American Indians look upon the Beaver with great respect. They believe that it is possessed of a degree of intelligence second only to that of man. Some Indians even assert that it possesses an immortal soul. Its sagacity is certainly very strong and it will easily adapt itself to changed environments. Unlike the other rodents, it seems to reason before acting and will build its habitations in the form that the surrounding conditions demand for the construction of the most durable home.

The Beaver, especially when young, is quite easily domesticated. Various writers speak of finding tame Beavers in Indian villages, where they seemed to be perfectly at home and contented. They were allowed full liberty. "They seemed to feel quite comfortable in the society of the Indian women and children; they grew restless in their absence and showed much pleasure on their return."

The young, which number from two to three, are born blind, but are covered with fur. They usually obtain their sight in from eight to ten days, and are then led to the water by the mother.

Early in the nineteenth century Dr. George Shaw wrote as follows regarding the habits of the Beaver: "They collect in September their provisions of bark and wood; after which they enjoy the fruits of their labors, and taste the sweets of domestic happiness. Knowing and loving one another from habit, from the pleasures and fatigues, of a common labor, each couple join, not by chance, nor by the pressing necessities of nature, but unite from choice and from taste. They pass together the autumn and the winter. Perfectly satisfied with each other, they never separate. At ease in their cabins, they go not out but upon agreeable or useful excursions, to bring in supplies of fresh bark, which they prefer to what is too dry or too much moistened with water."
