There had been only one exception to Wolf’s hatred for mauling at strangers’ hands. A man came to The Place on a business call, bringing along a chubby two-year-old daughter. The Master warned the baby that she must not go near Wolf, although she might pet any of the other collies. Then he became so much interested in the business talk that he and his guest forgot all about the child. Ten minutes later the Master chanced to shift his gaze to the far end of the room. And he broke off, with a gasp, in the very middle of a sentence. The baby was seated astride Wolf’s back, her tiny heels digging into the dog’s sensitive ribs, and each of her chubby fists gripping one of his ears. Wolf was lying there, with an idiotically happy grin on his face and wagging his tail in ecstasy. No one knew why he had submitted to the baby’s tugging hands, except because she _was_ a baby, and because the gallant heart of the dog had gone out to her helplessness. Wolf was the official watch-dog of The Place; and his name carried dread to the loafers and tramps of the region. Also, he was the Boy’s own special dog. He had been born on the Boy’s tenth birthday, five years before this story of ours begins; and ever since then the two had been inseparable chums. One sloppy afternoon in late winter, Wolf and the Boy were sprawled, side by side; on the fur rug in front of the library fire. The Mistress and the Master had gone to town for the day. The house was lonely, and the two chums were left to entertain each other. The Boy was reading a magazine. The dog beside him was blinking in drowsy comfort at the fire. Presently, finishing the story he had been reading, the Boy looked across at the sleepy dog. “Wolf,” he said, “here’s a story about a dog. I think he must have been something like you. Maybe he was your great-great-great-great-grandfather. He lived an awfully long time ago—in Pompeii. Ever hear of Pompeii?” Now, the Boy was fifteen years old, and he had too much sense to imagine that Wolf could possibly understand the story he was about to tell him. But, long since, he had fallen into a way of talking to his dog, sometimes, as if to another human. It was fun for him to note the almost pathetic eagerness wherewith Wolf listened and tried to grasp the meaning of what he was saying. Again and again, at sound of some familiar word or voice inflection, the collie would pick up his ears or wag his tail, as if in the joyous hope that he had at last found a clue to his owner’s meaning. “You see,” went on the Boy, “this dog lived in Pompeii, as I told you. You’ve never been there, Wolf.” Wolf was looking up at the Boy in wistful excitement, seeking vainly to guess what was expected of him.
