The expression of Calumet's face was as hard and inscrutable as the desert itself; the latter's filmy haze did not more surely shut out the mysteries behind it than did Calumet's expression veil the emotions of his heart. He turned from the desert to face the plateau, from whose edge dropped a wide, tawny valley, luxuriant with bunch grass--a golden brown sweep that nestled between some hills, inviting, alluring. So sharp was the contrast between the desert and the valley, and so potent was its appeal to him, that the hard calm of his face threatened to soften. It was as though he had ridden out of a desolate, ages-old world where death mocked at life, into a new one in which life reigned supreme. There was no change in Calumet's expression, however, though below him, spreading and dipping away into the interminable distance, slumbering in the glare of the afternoon sun, lay the land of his youth. He remembered it well and he sat for a long time looking at it, searching out familiar spots, reviving incidents with which those spots had been connected. During the days of his exile he had forgotten, but now it all came back to him; his brain was illumined and memories moved in it in orderly array--like a vast army passing in review. And he sat there on his pony, singling out the more important personages of the army--the officers, the guiding spirits of the invisible columns. Five miles into the distance, at a point where the river doubled sharply, rose the roofs of several ranch buildings--his father's ranch, the Lazy Y. Upon the buildings Calumet's army of memories descended and he forgot the desert, the long ride, the bleak days of his exile, as he yielded to solemn introspection. Yet, even now, the expression of his face did not change. A little longer he scanned the valley and then the army of memories marched out of his vision and he took up the reins and sent the pony forward. The little animal tossed its head impatiently, perhaps scenting food and companionship, but Calumet's heavy hand on the reins discouraged haste. For Calumet was in no hurry. He had not yet worked out an explanation for the strange whim that had sent him home after an absence of thirteen years and he wanted time to study over it. His lips took on a satiric curl as he meditated, riding slowly down into the valley. It was inexplicable, mysterious, this notion of his to return to a father who had never taken any interest in him. He could not account for it. He had not been sent for, he had not sent word; he did not know why he had come. He had been in the Durango country when the mood had struck him, and without waiting to debate the wisdom of the move he had ridden in to headquarters, secured his time, and--well, here he was. He had pondered much in an effort to account for the whim, carefully considering all its phases, and he was still uncertain.
