The Siberian fox is one of those wise creatures that has defied in a most extraordinary way his handicaps, and, refusing to admit them, has boldly selected the strangest dwelling-place known to the animal world—the horn of the mountain sheep. This unique dwelling-place has been the home of the Siberian fox for ages, and his ancestors have known no other. The mountain sheep, which are giants among their kind, have the longest horns in proportion to their size of any animal in existence. The argali of Siberia is the largest of all sheep, and is equal in bulk and weight to an average-sized ox, with horns proportionally large. The horns of these animals are strikingly like those of the Rocky Mountain sheep of America, except they are much larger. They spring up from the forehead, tilt backward, then boldly curve below the muzzle, before finally again pointing upward and tapering into a sharp and delicate point. They are hollow, though exceedingly stout and elastic, and strengthened on the outside by a number of ridges or horny rings set very close together. They are found in large numbers in this land of perpetual ice and snow, and it is thought that they break from the sheep's heads very easily.

It is not uncommon to find them lying in a spot which has been a battlefield, where two sheep in attempting to settle some dispute have fought and fallen. It is not long after they have thus fallen before they are utilised by Mr. Fox. He stores himself carefully away in these roomy horns, one of which Mrs. Fox uses as a nursery, finding it a snug, safe, and warm place to rear her little family.

The other varieties of foxes, especially the grey and red, are not so skilled in home-making. This may be due to the fact that they do not have need of such elaborate houses as their arctic cousins. Again, it may be that the existence of numerous deserted homes of badgers, or even rabbits, makes it unnecessary for them to spend their time in building homes of their own. It is much easier to enlarge the ready-made burrow of a rabbit than to dig a new tunnel, of course.

If there is no ready-made burrow to be had, then the wise fox sets to work and scoops out his own. Herein he sleeps all the day, and comes forth only at night. A small chamber from the main room serves as the nursery, and here the babies are born and nurtured. Nothing is more beautiful than to see the entire family—mother, father, and children—come forth at evening to play. The young are as sportive as pups, but they never wander far from home. Their broad heads, grey coats, short tails and awkward appearance would lead no one to think that they were the children of handsome, nimble-limbed, intelligent Mrs. Fox!

Woe to the dog that enters Mrs. Fox's home! She is a pugilist of the first order, and knows how to fight far better than the average bull terrier. It requires a very savage dog to kill her, and he is apt to be minus an ear when the battle is over.

Red and grey foxes are similar in intelligence, but differ in many other ways: the former are like the gipsies in always moving about from place to place, while the latter stick to one general locality, although their hunting-grounds may range for several miles in all directions. Red foxes seem actually to enjoy being hunted by dogs; in most cases they will outrun the dogs, and rarely seek protection from caves or rocks.

The grey fox, on the other hand, cares little for racing, but seeks protection among rocky cliffs where the dogs are at a disadvantage. Here none but the smallest canines may enter the holes and crannies, and they are usually wise enough to stay out. Hunters are thoroughly familiar with the tactics of the fox family, and therefore select the red ones for their sport.

The foxes are truly famed for their cunning, and when other animals try to play tricks on them, the trick usually turns out in the foxes' favour. During the winter season these wise creatures are sometimes hard pressed for food. Birds and small animals are hard to catch, and the farmers' chicken houses are closed. It is then that the wise fox needs all his wit and wisdom, for he oftentimes becomes the hunted as well as the hunter. His chief enemies are the puma and the timber wolf, but they are seldom able to get him.

The prairie-dog is so talented that he might be classed under several headings; he is sociable, a burrower, and especially gifted in the art of constructing underground "dog towns." He is rarely called by his Indian name, Wish-ton-wish, and we know him only as the prairie-dog. Evidently he was given this name because of his yelping bark, which resembles the cry of a young domestic dog.

He is a good-looking but rather curious little animal. He has a round, flat head, and garish-red fur, and a stout little body. He makes an affectionate pet, and loves the society of human beings. When he decides to start a town, he usually succeeds, for he is an exceedingly prolific animal, and his extensive burrows seem to have no ends. They are rather large, and run to great depths. In the western part of the United States, especially on the big prairies, the prairie-dog towns often cover large areas. They are usually dug in a sloping direction, and descend four to six feet in depth, and then suddenly rise upward again. Hundreds of these little tunnels are dug in such close proximity to each other that it is quite unsafe for cattle and horses to pass over them. This is the chief reason why ranchmen do not like the otherwise harmless little animals of the prairies.
