Thrusting it into his belt, he again made use of the cruel spur. With wild, killing bounds, the tortured animal brought his merciless rider nearer his foe.

Again Colton leveled a pistol—his second revolver. At its sharp report, the horse bestrode by the Night-Hawk leader gave a sudden bound, that told the bullet had found its mark.

The pursuer laughed aloud, and leveled his weapon once more. The pursued uttered a fierce despairing curse and turning in his saddle, fired three shots in quick succession at his relentless pursuer.

Fortune favored him in the result, for though scarcely pausing for aim, one missile foiled Colton’s hopes. With a shrill scream of pain, the noble brute stumbled and fell, casting the settler headlong to the ground. A bullet had struck its foreleg, that already overtasked, gave way, causing the heavy fall.

Morton heard the fall, and glancing back, uttered an exultant laugh. For a moment he pressed hard upon the bit, as though he would return to contemplate his triumph, but then, altering his mind, he spurred on.

He was well-nigh disabled, and did not know how many or close were his pursuers. He was in no condition for a fight, just then. His wound, freely bleeding, already caused him to feel faint, his head beginning to swim dizzily.

Added to this he felt his horse weaken and act as though failing. For a moment he wondered at this, for it was his own animal, a proved good one, but then he divined the cause. One or more of the settler’s bullets had found their mark.

With hard-drawn breath and gritting teeth the outlaw glanced over his shoulder. To his joy the prairie was clear of pursuers. Then Colton had been alone!

The horse twitched his tail, and his ears drooped. Morton knew what these symptoms meant, and he prepared for the result. Drawing hard upon the reins, he slackened his speed. It was time. The poor brute was trembling convulsively, the blood oozing from its nostrils and hanging lip.

Morton sprung to the ground, with a fierce curse. The horse staggered when relieved from his weight, and gave a faint whicker as it turned its head toward its master. But that was all. With an almost human groan it fell forward, dead.
