But just as the howl was on the verge of bursting from the full throat, the wide-opened mouth was closed, the paroxysms ceased, and he looked long and steadily at the retreating man. Suddenly Wolf turned his head, and over his shoulder just as steadily regarded Walt. The appeal was unanswered. Not a word nor a sign did the dog receive, no suggestion and no clew as to what his conduct should be. A glance ahead to where the old master was nearing the curve of the trail excited him again. He sprang to his feet with a whine, and then, struck by a new idea, turned his attention to Madge. Hitherto he had ignored her, but now, both masters failing him, she alone was left. He went over to her and snuggled his head in her lap, nudging her arm with his nose--an old trick of his when begging for favors. He backed away from her and began writhing and twisting playfully, curvetting and prancing, half rearing and striking his forepaws to the earth, struggling with all his body, from the wheedling eyes and flattening ears to the wagging tail, to express the thought that was in him and that was denied him utterance. This, too, he soon abandoned. He was depressed by the coldness of these humans who had never been cold before. No response could he draw from them, no help could he get. They did not consider him. They were as dead. He turned and silently gazed after the old master. Skiff Miller was rounding the curve. In a moment he would be gone from view. Yet he never turned his head, plodding straight onward, slowly and methodically, as though possessed of no interest in what was occurring behind his back. And in this fashion he went out of view. Wolf waited for him to reappear. He waited a long minute, silently, quietly, without movement, as though turned to stone--withal stone quick with eagerness and desire. He barked once, and waited. Then he turned and trotted back to Walt Irvine. He sniffed his hand and dropped down heavily at his feet, watching the trail where it curved emptily from view. The tiny stream slipping down the mossy-lipped stone seemed suddenly to increase the volume of its gurgling noise. Save for the meadow larks, there was no other sound. The great yellow butterflies drifted silently through the sunshine and lost themselves in the drowsy shadows. Madge gazed triumphantly at her husband. A few minutes later Wolf got upon his feet. Decision and deliberation marked his movements. He did not glance at the man and woman. His eyes were fixed up the trail. He had made up his mind. They knew it. And they knew, so far as they were concerned, that the ordeal had just begun. He broke into a trot, and Madge's lips pursed, forming an avenue for the caressing sound that it was the will of her to send forth. But the caressing sound was not made. She was impelled to look at her husband, and she saw the sternness with which he watched her. The pursed lips relaxed, and she sighed inaudibly.
