The stoat preys upon rather larger animals than do other weasels, and many a hare and rabbit falls victim to its sharp little fangs. Strange to say, when one of these creatures is being followed by a stoat it seems almost paralyzed with fear, and instead of making its escape by dashing away at its utmost speed, drags itself slowly and painfully over the ground, uttering shrill cries of terror, although it has not been injured at all.
In poultry-yards the stoat is sometimes terribly mischievous. One stoat has been known to destroy as many as forty fowls in a single night. So both the gamekeeper and the farmer have very good reason for disliking it. But in some ways it is really very useful. It kills large numbers of mice and rats and voles, which often do such damage in the fields. And if we could set the good which it does against the evil, we should find that the former more than makes up for the latter.
The Polecat
This animal was formerly very common in Great Britain. But owing to its mischievous habits it has been greatly persecuted, and now it is very seldom met with. It is a good deal larger than the stoat, being nearly two feet in length from the nose to the tip of the tail, and you would think, on looking at it, that its fur was brown, yet it scarcely has a brown hair on the whole of its body. The fact is that the long outer hairs are so dark as to be almost black, while the soft under-fur next the skin is pale yellow; and as the inner coat shows through the outer one, the effect is very much the same as if the whole of the fur were brown.
The polecat is sometimes called the foumart. This name is formed from the two words foul marten, and has been given to the animal because it looks like a marten, and has a most foul and disagreeable smell. In its habits it is very much like the stoat. It comes out chiefly by night, and preys upon any birds or small animals which it may meet with, following rabbits down their burrows, tracking hares to their "forms," and sometimes killing nearly all the poultry, geese, and turkeys in a farmyard. Early in April it makes a kind of nest in a deserted rabbit-hole, or in a crevice among the rocks, and there brings up its family of from three to eight little ones.
The animal called polecat in North America is the skunk, of which we shall speak soon; the name is particularly applied to the common skunk of the Northeastern States and Canada.
The Ferret
You know that the ferret is much used in hunting rabbits and rats. It appears to be really a variety of the polecat, and is usually of a yellowish white color with pink eyes. But there is also a brown form, which is generally called the polecat-ferret. It is known only in a domesticated form.
In some of the Western United States—Kansas, Colorado, etc.—is found the black-footed ferret, "often called prairie-dog hunter because its specialty is the killing of prairie-dogs." It has not become very well known to animal students, for it dwells in burrows and hunts at night.
