Pine-weasels are as common in the northern parts of America as they are in Europe and Asia. They are found in Canada, at Hudson's Bay, and as far north in Asia as the kingdom of Tonquin and the empire of China. They must not, however, be confounded with the sable, an animal whose fur is much more precious. The sable is black, but the pine-weasel is brown and yellow; the brown part of the skin is the most in estimation, and that extends along the back to the very extremity of the tail. _Engraved for Barr's Buffon._ [Illustration: FIG. 66. _Pole Cat._] [Illustration: FIG. 67. _Ferret._] THE POLECAT. This animal, (_fig. 66._) greatly resembles the marten in temperament, disposition, habits, and form of its body. Like him he approaches our dwellings, mounts to their roofs, and settles himself in hay-lofts, barns, and unfrequented places; from whence he steals by night into farm-yards, aviaries, and pigeon-houses, where, without making so much noise as the marten, he does more mischief; he twists off all their heads, and then carries them away, one by one, to his hole or dwelling. If, as it often happens, he cannot convey them away entire, from the smallness of the entrance, he eats the brains on the spot, and then retires with their heads. He is particularly fond of honey, will attack the hives in winter, and force the bees to abandon them. They are scarcely ever found at any great distance from inhabited places. They copulate in spring, when the males will fiercely contend on the roofs and sheds for the female. They then leave her, and go into the fields or woods for the summer, but she remains in her dwelling, and does not take her young ones out till towards the end of the summer; she produces from three to five, does not suckle them long, but soon accustoms them to suck blood, and the eggs of birds. In towns they chiefly subsist on prey, and in the fields or woods on what the chace affords them; when in the latter they fix their residence in the burrows of rabbits, clefts of rocks, or trunks of hollow trees, from whence they issue at night in quest of the nests of partridges, larks, and quails; they climb trees to get at those of other birds; are constantly on the watch for rats, field-mice, and moles, and are at continual war with the rabbit, who cannot escape, as they enter their burrows with ease. A single family of polecats is sufficient to destroy a whole warren; and indeed this would be a simple method of diminishing their number where they are found too numerous.
