We must conclude our account by again quoting Captain Hardy. Of the infatuation of this animal for castoreum he saw several instances. "A trap was fastened by its steel chain to a stake, to prevent the beaver, when caught, taking it away. It slipped, however, and the beaver swam away with the trap, and it was looked upon as lost. Two nights afterwards he was again taken in a trap, with the other fast on his thigh. Another time a beaver, passing over a trap to get the castoreum, had his hind-leg broken. With his teeth he cut the broken leg off, and went away. It was supposed that he would not come again; but two nights afterwards he was found fast in a trap--in each case tempted by the castoreum. The stake was always licked, or sucked, clean. The substance seems to act as a soporific, as the creatures, after tasting it, always remain a day without coming out of their houses. So wary generally are the beavers, that a trapper is always careful not to leave his scent on the spot. To avoid this he frequently cuts down a tree, and walks on its branches towards the edge of the path, afterwards withdrawing it, and plentifully sprinkling water around." The Indians and Canadian voyageurs eat the flesh of the beaver, esteeming it, when roasted with the skin on--the hair having been singed off--the most dainty of dishes. Early in this century, when beaver fur was much in demand for the manufacture of hats, upwards of 120,000 skins were exported from Quebec alone in one year. The warfare long waged against the unfortunate rodents now goes on with somewhat diminished activity. A change of fashion--the substitution of silk for beaver--has probably saved them from utter extermination. The scientific name of their tribe, _Castor_, was long a popular term for a hat; but now that their fur has ceased to be employed as formerly, the term itself appears to have gone out of use.
