They watched him scramble backward into the thicket, then proceeded on their way. Several minutes later, rounding a turn in the trail where the descent was less precipitous, he joined them in the midst of a miniature avalanche of pebbles and loose soil. He was not demonstrative. A pat and a rub around the ears from the man, and a more prolonged caressing from the woman, and he was away down the trail in front of them, gliding effortlessly over the ground in true wolf fashion. In build and coat and brush he was a huge timber-wolf; but the lie was given to his wolfhood by his color and marking. There the dog unmistakably advertised itself. No wolf was ever colored like him. He was brown, deep brown, red-brown, an orgy of browns. Back and shoulders were a warm brown that paled on the sides and underneath to a yellow that was dingy because of the brown that lingered in it. The white of the throat and paws and the spots over the eyes was dirty because of the persistent and ineradicable brown, while the eyes themselves were twin topazes, golden and brown. The man and woman loved the dog very much; perhaps this was because it had been such a task to win his love. It had been no easy matter when he first drifted in mysteriously out of nowhere to their little mountain cottage. Footsore and famished, he had killed a rabbit under their very noses and under their very windows, and then crawled away and slept by the spring at the foot of the blackberry bushes. When Walt Irvine went down to inspect the intruder, he was snarled at for his pains, and Madge likewise was snarled at when she went down to present, as a peace-offering, a large pan of bread and milk. A most unsociable dog he proved to be, resenting all their advances, refusing to let them lay hands on him, menacing them with bared fangs and bristling hair. Nevertheless he remained, sleeping and resting by the spring, and eating the food they gave him after they set it down at a safe distance and retreated. His wretched physical condition explained why he lingered; and when he had recuperated, after several days' sojourn, he disappeared. And this would have been the end of him, so far as Irvine and his wife were concerned, had not Irvine at that particular time been called away into the northern part of the state. Riding along on the train, near to the line between California and Oregon, he chanced to look out of the window and saw his unsociable guest sliding along the wagon road, brown and wolfish, tired yet tireless, dust-covered and soiled with two hundred miles of travel.
