Asleep she exercised upon him an even more disturbing effect than when awake, for now he could study her beauty deliberately, from the loose pile of warm, red hair to the narrow, tight-laced boots. What he saw was altogether delightful. Her slightly parted lips offered an irresistible attraction--almost an invitation; the heat had lent a feverish flush to her cheeks; Dave could count the slow pulsations of her white throat. He closed his eyes and tried to quell his unruly longings. He was a strong man; adventurous days and nights spent in the open had coarsened the masculine side of his character, perhaps at expense to his finer nature, for it is a human tendency to revert. He was masterful and ruthless; lacking obligations or responsibilities of any sort, he had been accustomed to take what he wanted; therefore the gaze he fixed upon the sleeping woman betrayed an ardor calculated to deepen the color in her cheeks, had she beheld it. And yet, strangely enough, Dave realized that his emotions were unaccountably mixed. This woman's distress had, of course, brought a prompt and natural response; but now her implicit confidence in his honor and her utter dependence upon him awoke his deepest chivalry. Then, too, the knowledge that her life was unhappy, indeed tragic, filled him with a sort of wondering pity. As he continued to look at her these feelings grew until finally he turned away his face. With his chin in his hands he stared out somberly into the blinding heat. He had met few women, of late years, and never one quite like this--never one, for instance, who made him feel so dissatisfied with his own shortcomings. After a time he rose and withdrew to the shelter of another tree, there to content himself with mental images of his guest. But one cannot sleep well with a tropic sun in the heavens, and since there was really nothing for her to do until the heat abated, Alaire, when she awoke, obliged the Ranger to amuse her. Although she was in fact younger than he, married life had matured her, and she treated him therefore like a boy. Law did not object. Mrs. Austin's position in life was such that most men were humble in her presence, and now her superior wisdom seemed to excite the Ranger's liveliest admiration. Only now and then, as if in an unguarded moment, did he appear to forget himself and speak with an authority equaling her own. What he said at such times indicated either a remarkably retentive memory or else an ability to think along original lines too rare among men of his kind to be easily credited. For instance, during a discussion of the Mexican situation--and of course their talk drifted thither, for at the moment it was the one vitally interesting topic along the border--he excused the barbarous practices of the Mexican soldiers by saying:
