He reached the granite ridge back of Medina's about four o'clock in the afternoon. He was tired, for he had been going since daylight, and for a part of the time at least he had been going on foot, climbing the steep, rocky sides of peaks for the sake of what he might see from the top, and then climbing down again for sake of what some one else might see if he stayed too long. His high-heeled riding boots that Helen May so greatly admired were very good-looking and very comfortable when he had them stuck into stirrups to the heel. But they had never been built for walking. Therefore his feet ached abominably. And there was the heat, the searing, dry heat of midsummer in the desert country. He was dog tired, and he was depressed because he had not seemed able to accomplish anything with all his riding and all his scanning of the country. He climbed slowly the last, brown granite ridge, the ridge behind Estan Medina's house. He would watch the place and see what was going on there. Then, he supposed he should go back and watch _Las Nuevas_, though his chief seemed to think that he had discovered enough there for their purposes. He had sent on the pamphlets, and he knew that when the time was right, _Las Nuevas_ would be muzzled with a postal law and, he hazarded, a seizure of their mail. What he had to do now was to find the men who were working in conjunction with _Las Nuevas_; who were taking the active part in organizing and in controlling the Mexican Alliance. So far he had not hit upon the real leaders, and he knew it, and in his weariness was oppressed with a sense of failure. They might better have left him in Texas, he told himself glumly. They sure had drawn a blank when they drew him into the Secret Service, because he had accomplished about as much as a pup trying to run down a coyote. A lizard scuttled out of his way, when he crawled between two boulders that would shield him from sight unless a man walked right up on him where he lay--and Starr did not fear that, because there were too many loose cobbles to roll and rattle; he knew, because he had been twice as long as he liked in getting to this point quietly. He took off his hat, telling himself morosely that you couldn't tell his head from a lump of granite anyway, when he had his hat off, and lifted his glasses to his aching eyes. The Medina ranch was just showing signs of awakening after a siesta. Estan himself was pottering about the corral, and Luis, a boy about eighteen years old, was fooling with a colt in a small enclosure that had evidently been intended for a garden and had been permitted to grow up in weeds and grass instead.
