A most spirited and exciting chase occurs when the farm-dog gets close upon one in the open field, as sometimes happens in the early morning. The fox relies so confidently upon his superior speed, that I imagine he half tempts the dog to the race. But if the dog be a smart one, and their course lies down hill, over smooth ground, Reynard must put his best foot forward; and then, sometimes, suffer the ignominy of being run over by his pursuer, who, however, is quite unable to pick him up, owing to the speed. But when they mount the hill, or enter the woods, the superior nimbleness and agility of the fox tell at once, and he easily leaves the dog far in his rear. For a cur less than his own size he manifests little fear, especially if the two meet alone, remote from the house. In such cases, I have seen first one turn tail, then the other. A novel spectacle often occurs in summer, when the female has young. You are rambling on the mountain, accompanied by your dog, when you are startled by that wild, half-threatening squall, and in a moment perceive your dog, with inverted tail and shame and confusion in his looks, sneaking toward you, the old fox but a few rods in his rear. You speak to him sharply, when he bristles up, turns about, and, barking, starts off vigorously, as if to wipe out the dishonor; but in a moment comes sneaking back more abashed than ever, and owns himself unworthy to be called a dog. The fox fairly shames him out of the woods. The secret of the matter is her sex, though her conduct, for the honor of the fox be it said, seems to be prompted only by solicitude for the safety of her young. One of the most notable features of the fox is his large and massive tail. Seen running on the snow, at a distance, his tail is quite as conspicuous as his body; and, so far from appearing a burden, seems to contribute to his lightness and buoyancy. It softens the outline of his movements, and repeats or continues to the eye the ease and poise of his carriage. But, pursued by the hound on a wet, thawy day, it often becomes so heavy and bedraggled as to prove a serious inconvenience, and compels him to take refuge in his den. He is very loath to do this; both his pride and the traditions of his race stimulate him to run it out, and win by fair superiority of wind and speed; and only a wound or a heavy and mopish tail will drive him to avoid the issue in this manner. To learn his surpassing shrewdness and cunning, attempt to take him with a trap. Rogue that he is, he always suspects some trick, and one must be more of a fox than he is himself to overreach him. At first sight it would appear easy enough. With apparent indifference he crosses your path, or walks in your footsteps in the field, or travels along the beaten highway, or lingers in the vicinity of stacks and remote barns. Carry the carcass of a pig, or a fowl, or a dog, to a distant field in midwinter, and in a few nights his tracks cover the snow about it.
