At sunrise the following morning Donald once more turned his face toward the valley, whence he had climbed lightheartedly less than two days previous. He had come with a beloved companion. He went alone, save for crowding memories--some bright, but far more black as storm-clouds and shot with malignant flashes of lightning. His vacation--a travesty on the name--was ended; the castle which his dreams had built on this remote mountain was a shattered ruin. Yet, through the dark series of crowding events, ran a fine thread of gleaming gold, and Donald felt that it had not been broken by his departure. No, it was spun by Destiny to stretch on and on into the unseen future, at once for him a guide-line to a higher manhood, and a tie binding his life to that of the girl whose pathway--starting so far removed from his--had so strangely converged with it. To continue his hunting trip in another location, with Mike no longer his companion in it, was unthinkable. The empty spaces made the void in his heart unbearable, and he at once returned to Boston and joined his family at their summer home, to their amazement and delight. But the man now returned to them after little more than a week's absence was vastly different from the one who had left. All marked the alteration in him, and over and over in family council tried, vainly, to account for it, for Donald had withheld far more than he told of his experiences, and minimized what he did tell. But he knew, as well as they, that a new chord had been struck within him, and by its vibrations his whole life was being tuned anew. Something of the old boyishness and impetuosity was gone, a new purposefulness--not of the will but rather of the spirit--had supplanted it and engendered an unwonted serenity. Was it born of the words of the strange mountain prophet, or the impelling appeal of the no-less-strange mountain child, whose mysterious smile, though seen less frequently than on his first visit, still cast a spell over his senses, even in memory? He could not say. Whatever uncertainties had disturbed his heart before, when his thoughts had turned upon her, none now remained. The die was cast. Smiles had made her place in his life, and would always occupy it, but merely as a dear charge and comrade. Half-child, half-woman, she still appealed to him in both capacities as perhaps none other ever had; yet he could now admit that fact frankly, and at the same time tell himself that there was, there could be, nothing else. With the mists of uncertainty dispelled, and his mind purged of the passions which had, so unexpectedly, possessed it, Donald's life returned to its old ruts. His work absorbed him as before, he accepted Marion as more fully a part of his life than she had previously been, and, in so doing, found an unexpected contentment. If, at times, he still felt that she was not all that he might desire, at least she was of his class and he understood her thoroughly.
