“Missed!” he muttered, and at once gave a sharp whistle that brought his pony to him on the trot. He vaulted to the saddle and gave chase. It was rough going, but nothing in reason can stop a cow-pony. As sure footed as a mountain goat, as good a climber almost as a cat, Buck followed the flying horseman over perilous rock rims and across deep-cut creek beds. Pantherlike he climbed up the steep creek sides without hesitation, for the round-up had taught him never to falter at stiff going so long as his rider put him at it.

It was while he was clambering out of the sheer sides of a wash that Bannister made a discovery. The man he pursued was wounded. Something in the manner of the fellow’s riding had suggested this to him, but a drop of blood splashed on a stone that happened to meet his eye made the surmise a certainty.

He was gaining now—not fast, almost imperceptibly, but none the less surely. He could see the man looking over his shoulder, once, twice, and then again, with that hurried, fearful glance that measures the approach of retribution. Barring accidents, the man was his.

But the unforeseen happened. Buck stepped in the hole of a prairie dog and went down. Over his head flew the rider like a stone from a catapult.

How long Ned Bannister lay unconscious he never knew. But when he came to himself it was none too soon. He sat up dizzily and passed his hand over his head. Something had happened.

What was it? Oh, yes, he had been thrown from his horse. A wave of recollection passed over him, and his mind was clear once more. Presently he got to his feet and moved rather uncertainly toward Buck, for the horse was grazing quietly a few yards from him.

But half way to the pony he stopped. Voices, approaching by way of the bed of Dry Creek, drifted to him.

“He must ’a’ turned and gone back. Mebbe he guessed we was there.”

And a voice that Bannister knew, one that had a strangely penetrant, cruel ring of power through the drawl, made answer: “Judd said before he fainted he was sure the man was Ned Bannister. I’d ce’tainly like to meet up with my beloved cousin right now and even up a few old scores. By God, I’d make him sick before I finished with him!”

“I’ll bet y’u would, Cap,” returned the other, admiringly. “Think we’d better deploy here and beat up the scenery a few as we go?”
