"Um!" was all the remark Del Pinzo made as he brushed himself off. Bather a useless proceeding it would appear, for he was always dirty and unkempt to the last degree.

"Who is he?" asked Dick of Bud as the three boy ranchers rode along the homeward trail, now out of earshot of the man Bud had so unceremoniously roped.

"Oh, he's a sort of Mexican half breed," was the answer. "Not very safe to have on the range during round-up."

"Why not?" asked Nort, as he turned to catch a last glimpse of the
Mexican slinking off amid the foothills.

"Well, he and his kind don't stop to look at the brand on a steer if they happen to feel hungry," explained Bud. "They'll cut one out of the herd, or appropriate a maverick, or an unbranded calf, and feast up on it. They'll skin it, salt down the hide after they blur the brand, and get away with it."

"What's blurring a brand?" asked Dick.

"Putting a hot iron on it over the brand that's already there," explained Bud. "Some brands can be changed from one to another without much trouble, but when this can't be done a cattle thief will simply make a botch of the brand, and it's a pretty slick ranchman who will swear, out of hundreds of steers and calves, that any particular one is his, if he can't make out the brand or earmarks clearly."

"Earmarks?" questioned Nort.

"Sometimes we clip a piece out of a calf's ear," explained Bud, "as well as branding 'em. Each ranchman has his own particular earmark for his cattle. But either may be botched or blurred by a thief if he's cute enough."

"And does this Del Pinzo do that?" asked Nort, a little thrilled at having been in such close association with a cattle thief.
