. The American beaver and his works [microform]. Beavers; Castors. â¢j Mbt BEAVER CANALS, MEADOWS, AND TRAILS. 203. years a inisHionary among the Ojibwa Indians, who went upon the ishind and examined them. Beaver excavations on a hirge scale are very common in dis- tricts favorable for their occupation, and they are greatly diversified in character. At the upper end of the principal pond at the gorge, where the series of dams are found, there is a canal two hundred and fifty feet long, which enters the pond where it is too shallow for a beaver to swim below the surface of the water. To correct this inconvenience a channel was excavated in the bed of the pond for about fifty feet in length, the materials from which were thrown up on either side. Beaver meadows are properly among the works of the beavers, although consequences, merely, of their labor for other objects. Wliere dams are constructed, 'ohe waters first destroy the timber within the area cov- ered by the ponds. When the adjacent lands are low, thyy are occasionally overflown after heavy rains, and \i at all times saturated with water from the ponds. In course of time, the trees within the area affected are totally destroyed; in place of which a rank, lux- uriant grass springs up. A level meadow, iu the strict and proper sense of the terra, is thus formed; although much unlike the meadow of the ''^â -. ated farm. At a distance they appear to ^c level and smooth; but when you attempt to walk over them, they are found to be a series of hummocks formed of earth and a mass of coarse roots of grass rising about a foot high, while around each of them there is a narrow strip of bare and sunken ground. The bare spaces, which are but a few inches wide, have the appearance of innumerable water-courses through.
