He rested his rifle on the body of the dead horse and waited. Out on the plain the racing ponies began to swim in a haze. He could see them indistinctly, and he brushed a hand across his eyes.

"I'm going fast, Boxer," he muttered to the dog. "My sight is failing! I'm burning inside! And I know you're choking yourself, poor dog! It's a hard way to pipe out."

The dog whined sympathetically and pressed closer. A bullet whistled past the head of the man. He tightened his grip on his rifle, sought to take aim, and finally fired.

His bullet went wide of the target he sought, and a yell of derision floated to his ears through the hot air.

"No use!" he muttered huskily. "I'm done for![Pg 166] It's the finish! They can close right in and wipe me out!"

The savages seemed to know it, and they were drawing nearer.

Of a sudden out from the depths of a long barranca, a mighty fissure in the plain, produced in former ages by a convulsion of nature, or marking the course of a river—out from one end that rose to the surface of the plain not far from the circling savages, came a horse and rider. As the rider rose into view he began shooting with a magazine rifle, and his first bullet caused a redskin to lose his hold and tumble end over end in the dirt, while the pony galloped on.

The following Indian stooped and seemed to catch up his wounded comrade as he swept past.

The lone horseman rode straight at them in a reckless manner, working his repeater.

A pony was wounded, another plunged forward into the dirt. In another moment the redskins wheeled and were in full flight, astounded and demoralized by the attack, two of the horses carrying double, while another left drops of blood upon the ground.
