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.  Biding 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.

Now Irvine was a man of impulse, a poet.  He got off the train at the next station, bought a piece of meat at a butcher shop, and captured the vagrant on the outskirts of the town.  The return trip was made in the baggage car, and so Wolf came a second time to the mountain cottage.  Here he was tied up for a week and made love to by the man and woman.  But it was very circumspect love-making.  Remote and alien as a traveller from another planet, he snarled down their soft-spoken love-words.  He never barked.  In all the time they had him he was never known to bark.

To win him became a problem.  Irvine liked problems.  He had a metal plate made, on which was stamped:  “Return to Walt Irvine, Glen Ellen, Sonoma County, California.”  This was riveted to a collar and strapped about the dog’s neck.  Then he was turned loose, and promptly He disappeared.  A day later came a telegram from Mendocino County.  In twenty hours he had made over a hundred miles to the north, and was still going when captured.

He came back by Wells Fargo Express, was tied up three days, and was loosed on the fourth and lost.  This time he gained southern Oregon before he was caught and returned.  Always, as soon as he received his liberty, he fled away, and always he fled north.  He was possessed of an obsession that drove him north.  The homing instinct, Irvine called it, after he had expended the selling price of a sonnet in getting the animal back from northern Oregon.
