Cleverly disregarding his taciturnity she kept up a merry chatter as they rode along, finally drawing him skillfully into a discussion of the geological features of the interesting region which they were slowly traversing; like every mining expert he was a bit professionally pedantic on this subject, and to this woman of abnormally clear perceptions it was a positive pleasure to him to impart the really great information with which his mind was stored. Once she got him warmed up to his subject he waxed enthusiastic in his dissertation on dykes, fissures, blanket veins and the like, even riding out of their course to point out confirming formations and collect specimens of their characteristic components. By the time they reached the embowered little glade in the canyon his sullenness was completely dissipated, and he kissed her very passionately as he lifted her from her horse. There was much of the old fire in him as she clung distractingly about his neck, and her eyes gleamed with triumph. So absorbed had they become in each other that neither noticed the slinking figure which stole out of the glade at the sound of their approach, or the charcoal of a hastily-extinguished fire swirling in the eddies of the little pool. And mercifully they did not know, as they stood there in close-held rapture, drinking with clinging lips the Lethe of all things save love, that twenty feet away, from the vantage of a dense clematis tangle veiling a clump of dwarf box-elder, a pair of evil eyes burned above a snarling mouth, as a grimy hand drew cautiously back the firing bolt of a Mauser. CHAPTER XXII THE RENUNCIATION Ballard, riding ahead of his posse, reined in his horse sharply at the head of the trail leading down to the stream as a shot crackled viciously in the depths of the canyon below. There was no mistaking that crisp, whip-like report of a small-calibered, high-pressure rifle cartridge, and he wondered much that it was not accompanied by the whine of the long metal-cased bullet about his ears. For the last twenty-four hours had he been in momentary expectation of that sinister song, of a possible succeeding agony of blindness, for he realized that he was now in the hands of the gods, and more or less at the mercy of the desperate man whom he had been relentlessly pursuing for the last three days, a man who would just as relentlessly kill him if the opportunity offered, a man who knew every inch of these mountain fastnesses in which he had taken refuge in his last extremity. But despite all hazards of ambush he had kept doggedly on the trail, and now he was within reach of his quarry. Hurriedly directing two of his best mounted followers to cover the canyon's mouth below, and the remaining two to guard the only other possible exit above, he rode at breakneck speed down the precipitous trail, spurred to recklessness by a woman's wailing scream.
