The stolen pup was the only one in the litter which had not been sold or else bespoken. For the Logan collies had a just fame in the region. But that one pup had been set aside by Dick Logan as a future housedog. This because he was the largest and strongest and liveliest of the seven; and because of the unusually wide white ruff which encircled his broad shoulders like a shawl. Dick had named the youngster “Ruff,” because of this adornment. And now he was liked to have no use for the name. Ruff, meantime, was gaining his education, such as it was, far more quickly than his super-domesticated collie mother and Dick together could have imparted it to him. By example and by swift punishment in event of disobedience, Pitchdark was teaching him to crouch, flattened and noiseless, at sound or scent of man or of alien beast. She was teaching him to worm his pudgy little body snakelike through grass and undergrowth and to make wise use of every bit of cover. She was teaching him—as foxes have taught their young for a million years—the incredible cunning of her race and the fear of man. By the time his legs could fairly support him on the briefest of journeys, she was teaching him to stalk game;—to creep up on foolish fieldmice, to confuse and head off young rabbits; and the like. Before he was fairly weaned she made him try his awkward prowess at finishing a rabbit-kill she had begun. With Ruff it was a case of kill or starve. For Pitchdark cut off natural supplies from him a full week earlier than his own gentle mother would have done. Pitchdark was a born schoolmistress in Nature’s grim woodland course of “eat or be eaten.” To her stern teachings the puppy brought a brain such as no fox could hope to possess. Ruff was a collie—member of a breed which can assimilate practically any mental or physical teachings, if taught rightly and at an early enough age. Pitchdark was teaching him rightly, if rigidly. Assuredly, too, she was beginning early enough. To the imparted cunning of the fox, Ruff added the brain of a highly sensitised collie. The combination was a triumph. He learned well-nigh as fast as Pitchdark could teach. If nine-tenths of the things she taught him were as reprehensible as they were needful, he deserved no less credit for his speed in mastering them and for his native ability to add to them. At an age when his brethren and sisters, back at the farm, were still playing aimlessly around the dooryard, Ruff was grasping the weird secrets of the wild. While they were still at the Teddy Bear stage of appealing helplessness, his fat body was turning lean and supple from raw food and from much exercise and from the nature of that exercise. While they were romping merrily with an old shoe, Ruff was creeping up on fieldmouse nests and on couchant quail, or he was heading off witlessly racing rabbits which his foster-mother drove toward the cul-de-sacs where she had stationed him.
