The food of the muskrat is varied. It loves the roots of several species of _nymphae_, but its favourite is _calamus_ root (_calamus_ or _acorus aromaticus_). It is known to eat shell-fish, and heaps of the shells of fresh-water muscles (_unios_) are often found near its retreat. Some assert that it eats fish, but the same assertion is made with regard to the beaver. This point is by no means clearly made out; and the closet naturalists deny it, founding their opposing theory, as usual, upon the teeth. For my part, I have but little faith in the "teeth," since I have known horses, hogs, and cattle greedily devour both fish, flesh, and fowl. The muskrat is easily tamed, and becomes familiar and docile. It is very intelligent, and will fondly caress the hand of its master. Indians and Canadian settlers often have them in their houses as pets; but there is so much of the rat in their appearance, and they emit such a disagreeable odour in the spring, as to prevent them from becoming general favourites. They are difficult to cage up, and will eat their way out of a deal box in a single night. Their flesh, although somewhat musky, is eaten by the Indians and white hunters, but these gentry eat almost everything that "lives, breathes, and moves." Many Canadians, however, are fond of the flesh. It is not for its flesh that the muskrat is so eagerly hunted. Its fur is the important consideration. This is almost equal to the fur of the beaver in the manufacture of hats, and sells for a price that pays the Indians and white trappers for the hardships they undergo in obtaining it. It is, moreover, used in the making of boas and muffs, as it somewhat resembles the fur of the pine marten or American sable (_Mustela martes_), and on account of its cheapness is sometimes passed off for the latter. It is one of the regular articles of the Hudson's Bay Company's commerce, and thousands of muskrat skins are annually obtained. Indeed, were it not that the animal is prolific and difficult to capture, its species would soon suffer extermination. The mode of taking it differs from that practised in trapping the beaver. It is often caught in traps set for the latter, but such a "catch" is regarded in the light of a misfortune, as until it is taken out the trap is rendered useless for its real object. As an amusement it is sometimes hunted by dogs, as the otter is, and dug out of its burrow; but the labour of laying open its deep cave is ill repaid by the sport. The amateur sportsman frequently gets a shot at the muskrat while passing along the bank near its haunts, and almost as frequently misses his aim. The creature is too quick for him, and dives almost without making a bubble. Of course once in the pool it is seen no more.
