Each trapper had ten steel traps allowed him. These he set every night, and visited every morning, sometimes oftener when practicable, selecting a spot in the stream where many trees had been cut down by beavers for the purpose of damming up the water. In some places as many as fifty tree stumps were seen in one spot, within the compass of half an acre, all cut through at about eighteen inches from the root. We may remark, in passing, that the beaver is very much like a gigantic water-rat, with this marked difference, that its tail is very broad and flat like a paddle. The said tail is a greatly-esteemed article of food, as, indeed, is the whole body at certain seasons of the year. The beaver's fore legs are very small and short, and it uses its paws as hands to convey food to its mouth, sitting the while in an erect position on its hind legs and tail. Its fur is a dense coat of a grayish-coloured down, concealed by long coarse hair, which lies smooth, and is of a bright chestnut colour. Its teeth and jaws are of enormous power; with them it can cut through the branch of a tree as thick as a walking-stick at one snap, and, as we have said, it gnaws through thick trees themselves. As soon as a tree falls, the beavers set to work industriously to lop off the branches, which, as well as the smaller trunks, they cut into lengths, according to their weight and thickness. These are then dragged by main force to the water-side, launched, and floated to their destination. Beavers build their houses, or "lodges," under the banks of rivers and lakes, and always select those of such depth of water that there is no danger of their being frozen to the bottom. When such cannot be found, and they are compelled to build in small rivulets of insufficient depth, these clever little creatures dam up the waters until they are deep enough. The banks thrown up by them across rivulets for this purpose are of great strength, and would do credit to human engineers. Their lodges are built of sticks, mud, and stones, which form a compact mass; this freezes solid in winter, and defies the assaults of that housebreaker, the wolverine, an animal which is the beaver's implacable foe. From this lodge, which is capable often of holding four old and six or eight young ones, a communication is maintained with the water below the ice, so that, should the wolverine succeed in breaking up the lodge, he finds the family "not at home," they having made good their retreat by the back-door. When man acts the part of housebreaker, however, he cunningly shuts the back-door _first_, by driving stakes through the ice, and thus stopping the passage. Then he enters, and, we almost regret to say, finds the family at home. We regret it, because the beaver is a gentle, peaceable, affectionate, hairy little creature, towards which one feels an irresistible tenderness. But to return from this long digression.
