When wolves are running they generally utter a series of dismal howls, which are so loud that they can be heard by any one miles away. And even a single wolf can make such an outcry that more than once a traveler, hearing one howl, has imagined that a large pack were in pursuit of him, and has climbed into a tree and spent the whole night among the branches before discovering his mistake. Wolves usually make their lairs among rocks, or in the trunk of a hollow tree, or among thick bushes. But sometimes they live in holes in the ground, which they seem to dig out for themselves. There are generally from six to ten cubs in a litter, which are born in the spring, and do not leave their parents for at least eight or nine months. Strange to say, the father often seems much fonder of them than the mother, for he will take care of them, and hunt for them, and teach them how to hunt for themselves for weeks after she has left them altogether. WOLVES IN INDIA The common wolf is by no means confined to Europe, but is also found in many parts of Asia, and throughout almost the whole of North America. In India, however, there is another kind of wolf which is rather smaller, and has very much shorter fur. It is seldom seen in large packs, and hardly ever howls as the common wolf does. It is not in the habit, as a rule, of attacking human beings. But now and then two or three of these animals will band together to attack a man, while sometimes they will prowl round the outskirts of a native village, in the hope of being able to carry off some of the smaller children. These animals have a very clever way, too, of killing deer. Three or four of them will creep quietly up and hide themselves near the spot where the deer are feeding. Then another will come dashing up from the opposite direction, the result, of course, being that when the frightened animals run away they pass close to the very place where their enemies are lying concealed. COYOTES On the great plains of North America lives a very handsome wolf called the coyote, or prairie-wolf. It is a good deal smaller than the common wolf, but has much thicker and longer fur, so that it looks bigger than it really is. And a very odd thing about it is that it is differently colored at different seasons of the year, being reddish yellowish brown in summer, and grayish, or even quite gray, in winter. The back is generally darker than the rest of the body, and the tail is rather long and very bushy. The coyote takes the place of the hyena as a scavenger, but has some of the habits of the fox. It catches birds and jackrabbits, and feeds on insects, as well as small rodents like prairie-dogs and mice. Its melancholy howls make night hideous to prairie-dwellers. It is the steady foe of young creatures, such as the fawns of deer. The skin of this animal is thick and makes good fur wraps.
