Judge Allison, portly and forty, sat on the porch of the Sunrise Hotel in Marysville. The judicial hands were clasped over the judicial stomach, and the judicial mind was at peace with all mankind. However, a six-shooter in a shoulder-holster nudged the judicial ribs beneath each arm-pit. For mankind is peevish and prone to hold grudges, and in order to secure an uninterrupted term on the bench a judge must be prepared for eventualities.

Tied to the hitching-rail in front of the hotel was a good-looking sorrel horse. It bore the Barred Twin Diamond brand. Judge Allison had bought the horse that very morning. He had bought him from the keeper of the dance hall, Mr. William Archer, who, it seemed, had five others for sale.

Judge Allison was delighted with his bargain. He knew a horse when he saw one, and he felt that he had gotten the best of Archer in the deal. True, as Archer had said, the sorrel was a little footsore, but two or three weeks of light work would cure that.

"Yes," mused the Judge, "a good animal. Sixteen hands high if he's an inch, and I'll bet he can run rings round any cow-pony in the community. By Jove, here come two unusually fine animals!"

Which last remark was called forth by the approach of two big rangy horses, a bay and a gray. The riders, very dusty, both of them, were hard-looking characters. A week's growth of stubble does not add to the appearance of any one. They were tall, lean men, these two, and one of them was exceedingly swarthy.

They dismounted at the hitching-rail, tossed the reins over their horses' heads, and went into the bar. Both, as they passed, glanced casually at the Judge's sorrel.

"Flying Diamond A," said the judge to himself, eying the strangers' mounts. "I don't believe I ever heard of that outfit. It must be a southwestern ranch."

Judge Allison had never heard of his sorrel's brand, the Barred Twin Diamond, either. But then the Judge knew Mr. William Archer, or thought he did, and to question the authenticity of the brand had not entered his head.

The two tall, lean riders would have been greatly pleased had they known of the ease with which the Judge read the brands on their horses' hips. It was a tribute to their skill in hair-branding. Pocket-knives in their hands, they had spent hours in a broiling hot draw altering the Flying M to the Flying Diamond A.

On paper it is ridiculously simple. Merely prolong upward, till they meet, the outer arms of the Flying M, and there you have it, a perfectly good Flying Diamond A. But it is quite another story when one's paper is the hide of a nervous horse which frantically objects to having its hair pinched out.
