"What, the man with the scar?"

"Yes. He is the cattle rancher whom Luke insisted was such a friend of his. I took a long chance and had the sheriff arrest him to-day. He is being held until you take a look to see if you can identify him. I hope you will be able to."

"Where is he?" asked the lad. "Tied up in the chuck wagon. I'll have him brought over."

"Hello, Bluff," greeted Tad, the instant he set eyes on the surly face of the prisoner.

"Hello, kid. Never saw me before, did you?"

"I should say I had. That's the man, Mr. Simms. There can be no doubt about it."

"And he is the fellow who caught and turned me over to the Indians," added Philip, shrinking away from the bearded face.

"Then I guess there is nothing more to be said," announced Mr. Simms, with a grim smile. "This man has been doing a crooked business for years, all up and down the trail. Of course he had accomplices, but we shall hardly get them. Nobody suspected him. The frequent thefts of stock and the killing of sheep was a mystery until you solved it, Master Tad. I wish I knew how to express my appreciation of what you have done for us."

"There is one favor you can do for me if you will, Mr. Simms."

"It is already granted. Name it."
