The others overtook him. They were carrying but single loads. But they did not pass him. He saw to that. He burst forward into even greater speed, clung to it grimly, forged into a position well in the lead. And he held this place--around him frenzied horses, frantic riders; behind him, to the distant rear, shot after shot echoing over the desert; before him the baking sands, shimmering heat-waves, sullen and silent. He raced on, swinging up over dunes, dropping into hollows, speeding across flats, mounting over dunes again, on and on toward the basin and the mouth of the canyon--and protection. But again disaster. Suddenly, out of the canyon poured the cheerful notes of a bugle. On the vibrant wings of the echoes, streaming into the basin from the canyon, swept a body of flying horsemen. Instantly he checked himself. Then his master sounded a shrill outcry, swung his head around violently, and lashed him forward again. He hurtled headlong, dashing toward the distant ridge, the peninsula jutting out into the desert. Grimly he flung out along this new course. But he kept his eyes to the left. He saw the horsemen there also swerve, saw them spread out like a fan, and felt his interest kindle joyously. For this was a race! It was a race for that ridge! And he must win! He must do this thing, for instinctively he knew that beyond it lay safety. There he could flee to some haven, while cut off from it, cut off by these steady-riding men on his left, he must submit to wretched defeat. So he strained himself harder and burst into fresh speed, finding himself surprised that he could. In the thrill of it he forgot his double load, forgot the close-pressing horses, forgot irritating dust. On he galloped, racing forward with machine-like evenness--on his left the paralleling horsemen, to his rear yelling and shooting, on his right his own men and horses, and for them he felt he must do big things.
