Dan nodded. He was a reticent man of about fifty-five with a bald head and a face of wrinkled leather.

"We'll git him sure," Phil spoke up, announcing his hope rather than his conviction. "Steve knows what he's doing, you bet."

Yeager himself was not so sure. Doubts tortured him as to the destination of Harrison. Perhaps, after all, he might be making for some refuge in the hills and not for Pasquale's headquarters. He knew that as soon as word reached them the Lazy B riders would begin to comb the desert in pursuit. But what were a dozen riders among these thousand hill pockets of the desert? The best chance was to catch the man at some one of the few water-holes. But if he pushed on at full speed the chances were all in his favor considering the long start he had.

The range-rider was astride the fastest horse in the Lunar stables. Steve had taken his pick of the mounts, for his work was cut out for him. Hitherto the luck had all been with Harrison. If Yeager had not met one of the old Lone Star boys, now riding for the Hashknife outfit, and stopped to join him in a long talk over their cigarettes, Steve would have reached Los Robles in time to spoil the man's plan. Or if he had gone direct to Mrs. Seymour instead of fooling away a good hour and a half in his room, he would have cut down his enemy's start by so much golden time.

Now all he could do was to get every foot of speed from his horse that could be coaxed. He rode like a Centaur, giving with his lithe, supple body to every motion of the animal. But though he took steep hillsides of shale on the run, the pony slithering down in a slide of rubble like a cat, the rider's alert eyes watched the footing keenly. He could afford if necessary to break a leg himself, but he could not afford to have the horse suffer such an accident. Not for nothing had he ridden on the roundup for many years. Few men even in Arizona could have negotiated safely such a bit of daredevil travel as he was doing this night.

His brains were busy, too, on the problem before him. Times and distances he figured, took into account the animals Harrison and Ruth were riding, estimated her strength and her companion's feverish haste to reach safety with her. They would have to stop at a water-hole somewhere, either on Gila Creek, or the old Pima camping-ground, or else at Lone Tree Spring. The most direct route to Noche Buena was by Lone Tree. Harrison was in a deuce of a hurry. Therefore he would choose the shortest way. So Yeager guessed and hoped.

His watch told him it was an hour past midnight when Steve drew close to Lone Tree Spring. He was following a sandy wash into the soft bed of which the hoofs of his horse sank without noise. They were perhaps two hundred yards from the spring when the ears of his pony lifted. That was enough for Yeager. He dismounted and trailed the reins, guessing that the wind had brought the scent of other horses to his own. Quietly he moved forward, rifle in hand ready for action.

The heart of him jumped when he caught sight of two picketed horses grazing on the bench above. He worked forward with infinite care along the bank of the wash till he reached the first of the cottonwoods. From here he could catch a glimpse of something huddled lying under the live-oak. This no doubt was the sleeping girl. The figure of a heavy-set man stood with his back to Yeager in silhouette against the skyline.

Yeager crawled forward another fifteen yards. A twig snapped under his knee. The figure in silhouette whirled. Steve rose at the same instant, rifle raised to his shoulder.

"Don't move," he advised quietly.
