The head of the divide was close now, scarcely a quarter of a mile in front of the fugitives. Hugh looked back as he galloped up into the pass. The buckskin was far in advance of the other pursuers.

The pass was short and narrow. At the very summit a huge boulder outcropped from the ridge. McClintock swung his labouring horse back of this, and at the same instant leaped to the ground. Swiftly he unclinched and drew the bay close to the flat face of the great rock. For the first time since the wild race had begun he took from its scabbard the navy revolver he carried.

He had not long to wait. There came the sound of a hoof striking the hard quartz of the ridge, then the thud of galloping feet. The express rider tensed his muscles. He was like a coiled spring as he crouched back of the boulder, a menace to life as deadly as a rattlesnake about to strike.

Smoothly he slid round the edge of the rock. The Piute, taken by surprise, jerked the buckskin sideways and tried to raise his rifle. Lightning flashed from McClintock’s six-shooter—once, twice. He dived forward and caught the bridle just as the redskin tumbled from the horse. The rifle clattered to the ground.

Hugh took one look at the Indian. It was enough. He would never steal another horse from the whites. The buckskin, frightened, tried to jerk away. Its new owner spoke gently, soothingly. He coaxed the startled animal to the rock and transferred the saddle from the back of Nevada Jim.

Already he could hear approaching horses. As rapidly as possible he cinched and swung astride. Yet an instant, and he was galloping down the western slope.

As he looked back, McClintock saw an Indian’s head and the upper part of his body rising and falling with the stride of a horse. He was the first of the pursuers coming up into the pass. There was a shout and the sound of a shot. A bullet struck a spurt of sand from the ground some yards ahead of the express rider. Other shots came, a scattering volley of them. Hugh had thrust his smoking revolver back into the scabbard. He did not attempt to draw it again. The primary business of the moment was to get the buckskin into its stride and widen the distance between him and his enemies.

Soon he was out of range. Bullets were still falling, but they struck the dust behind him. The buckskin was fast and willing. Nevada Jim, like many of the company horses, had a cross of Morgan blood. This horse was a mustang, but it had unusual speed and power. Hugh wondered whether the ranchman who had owned it had been killed when his place was raided.

The pursuit continued for several miles, but the Indians fell always farther to the rear. At last they dropped out. At least Hugh saw them no more.

It was time. McClintock was faint and dizzy. He could barely stick to the saddle by clinging with both hands to the pommel. His wound, irritated by the constant motion, hurt a great deal. The fever mounted in his blood.
