He mounted Rabbit again and made a detour of several miles so that he might come up on the ridge behind Medina's without running any risk of crossing the trail of the men he wanted to watch. About two o'clock he stopped at a shallow, brackish stream and let Rabbit rest and feed for an hour while Starr himself climbed another rocky pinnacle and scanned the country between there and Medina's.

The gate that let one off the main road and into the winding trail which led to the house stood out in plain view at the mouth of a shallow draw. This was not the trail which led out from the home ranch toward San Bonito, where Starr had been going when he saw the track of the mysterious automobile, but the trail one would take in going from Medina's to Malpais. The ranch house itself stood back where the draw narrowed, but the yellow-brown trail ribboned back from the gate in plain view.

Here again Starr was fated to get a glimpse and no more. He focussed his glasses on the main road first; picked up the Medina branch to the gate, followed the trail on up the draw, and again he picked up a man riding a bay horse. And just as he was adjusting his lenses for a sharper clarity of vision, the horse trotted around a bend and disappeared from sight.

Starr swore, but that did not bring the man back down the trail. Starr was not at all sure that this was the same man he had seen in the draw, and he was not sure that either was the man who had shot at him. But roosting on that heat-blistered pinnacle swearing about the things he didn't know struck him as a profitless performance, so he climbed down, got into the saddle again, and rode on.

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.

After a while a peona came out and fed the chickens, and hunted through the sheds for eggs, which she carried in her apron. She stopped to watch Luis and the colt, and Luis coaxed her to give him an egg, which he was feeding to the colt when his mother saw and called to him shrilly from the house. The peona ducked guiltily and ran, stooping, beside a stone wall that hid her from sight until she had slipped into the kitchen. The señora searched for her, scolding volubly in high-keyed Mexican, so that Estan came lounging up to see what was the matter.
