THE FOX AT HOME
The "coloured" foxes, including the red, the cross, the silver, and the black—the latter three being merely colour phases of the former and not separate species, as has frequently been proved, but all four having been found in the same litter—mate in February and March. They pair and remain faithful partners. The father also helps in feeding and caring for the young which are born about fifty days after the mating season. The litter contains from three to ten, and when a few weeks old the young are as playful and as interesting as domestic kittens. The den in which they are born may be a hollow tree, a hollow log, or more often an underground tunnel with several entrances and a storeroom besides the living chamber. The nest is never lined, but left quite bare and is kept clean. Their principal food is derived from mice, birds, fowl, and rabbits; and the parents frequently cache food for both their young and themselves. No wonder they are good providers, for what with their keen sense of scent and their great speed they seldom fail in their hunts. They are fond of open country and have an individual range of very few miles, perhaps ten at the most. In winter they run singly until the mating season; seldom are the tracks of more than two foxes seen together, and their principal enemies are men, wolves, lynxes, and dogs.
As the district through which we were passing was rich in fox-signs, Oo-koo-hoo set a number of traps. Such work takes time, and when we reached a well-wooded grove of second-growth birch, poplars, and—along a little creek—willows, we began to think of where we should camp for the night. Besides, the old hunter deemed it an ideal spot in which to set lynx and rabbit snares. So while the boys cut wood for the fire and brush for our beds, and then turned to the cooking of supper, Oo-koo-hoo cut a great mass of birch, poplar, and willow branches and tops, and threw them into piles, not only to attract the rabbits thither, but to afford them a prolonged feast for many weeks, and thus fatten them for his own use; moreover, the gathering of the rabbits would prove a strong attraction for the lynxes of the region. Sometimes, at such a spot, hundreds of rabbits will feed, and in winter time the place may become such a network of runways that if it happens to be a fairly open hillside one can see from half a mile away the shadows of the endless tracks that mark the glistening snow in all directions.
During the years of great plenty—which the Indians and traders assert come about every seventh year—the number of rabbits in some sections of the northern forest is almost beyond belief. Then a plague suddenly overtakes them, almost wiping them out of existence, and several years elapse before the disease disappears and they begin to increase again. The plague, of course, is the rabbit's greatest enemy, then follows the lynx, the fox, the wolf, and many other animals and even birds such as the owl and the hawk; but somewhere among that destructive group man plays a prominent part.
