"The most interesting feature of the animal creation in the Western Continent is, perhaps, the beaver (_Castor fiber_). These amphibia, indeed, occur in the northern parts of Europe and Siberia, but on comparatively so small a scale, both in number and size, that the beaver may be viewed with propriety as specially American. There appears to be absolutely no animal which makes so close an approach to human art and intelligence. The beaver builds his habitation either in a pond or in the channel of a river, converted into a pond by strong piles being laid across. This operation involves the greatest display of ingenuity. A tall tree is selected, and filed round with the teeth till it is undermined and falls across the stream. It is then fastened down by smaller trees and branches, brought often from a distance, and connected with earth. In the little lake thus formed, the beaver rears his abode to the height of two, three, or four stories, half above and half under the water, and with an opening into both elements. Stones and earth, as well as wood, are used in forming the walls, which, by the joint operation of the feet and the tail, are brought into a mass so solid as to be proof against the action of current, wind, and weather. The outside is plastered in the neatest manner, the floor kept excessively clean, strewed with box and fir. A large provision of food, consisting of bark and leaves, is stored up for the winter. The beavers possess a social and almost a moral existence. Each mansion contains from six to thirty inhabitants, who live together in the greatest harmony, and afford mutual aid and co-operation. From twelve to fourteen houses united form a village, containing thus a population of 200 or 300. "The flesh of these animals is much prized by the Indians and Canadian voyageurs, especially when roasted in the skin after the hair has been singed off. The enjoyment of this expensive luxury is of course restrained as much as possible by the fur traders. The Iroquois are the greatest beaver-catchers in Canada. Great injury has resulted from the indiscriminate capture of old and young, and the too frequent trenching of the same dams. It is known that in the year 1743 the amount of their skins brought into the ports of London and Rochelle exceeded 150,000, besides a considerable quantity introduced illicitly into Great Britain; while in 1837, the importation into London, from more than four times the extent of fur country formerly possessed, did not much exceed 800,000.
