They had met, the previous autumn, in the quaint old New England town where his people lived. She had come like a bit of the young West into the staid, old-fashioned setting of the place, and he had rejoiced in every trait that distinguished her from the conventional young lady of his acquaintance. To-day, as they rode side by side toward the broad-bosomed mountain to the southward, he told himself once more that her nature was like this Colorado atmosphere, in its absolute clearness and crispness. Such an air,--bracing, stinging, as it sometimes was,--could never turn really harsh and easterly; neither, perhaps, could it ever take on the soft languor of the summer sea. And Amy Lovejoy's nature would always have the finer, more individual quality of the high, pure altitude in which she had been reared. Possibly Stephen Burns had yet something to learn about that agreeable climate with which he was so ready to compare his love. The weather had been perfect since he came to Colorado. How could he suspect the meaning of a tiny wisp of vapor too slight to cast a visible shadow? And Amy chatted gaily on with Jack Hersey, as they cantered southward, while Stephen Burns, riding beside them, told himself with needless reiteration, that he was well content. One reason for content he certainly had at that moment, for he was a good horseman, as an accomplished gentleman is bound to be, and he was never quite insensible to the exhilaration of that delicious, rhythmic motion. They had passed through a gate which signified that the rolling acres of prairie on either hand, the winding road that lost itself in the distance, the pine-clad slope to the right, were all but a part of a great ranch. Herds of cattle were doubtless pastured within that enclosure, though nowhere visible to the holiday party riding and driving over their domain. Hundreds of prairie-dog holes dotted the vast field on either hand, and here and there one of the odd little fraternity scampered like a ball of gray cotton across the field, or sat erect beside his hole, barking shrilly, before vanishing, with a whisk of the tail, from sight. Stephen took so kindly to the little show, and made such commonplace exclamations of pleasure, that Amy felt a sudden relieved compunction and smiled upon him very graciously. "They are not a bit like what I expected," he said; "but they are such self-important, conceited little chaps that you can't help having a fellow-feeling with them!" "Hullo! There's a give-away!" Jack Hersey shouted; and he turned and repeated the remark for the benefit of a buckboard in the rear. Amy thought Jack very stupid and silly, and in her own heart, she promptly ranged herself on the side of her young minister. There was nothing subtle or elusive about her changes of mood, and Stephen profited by each relenting. For a few blissful moments, accordingly, he now basked in the full consciousness of her favor.
