"What makes you think that, Chub?" laughed Matt. "Don't a fellow ever do a little head-work except when things go crossways?"

"Everybody ain't shootin' off his mouth the hull blessed time like you, Chub," put in Welcome. "Whenever you talk it's like a lot o' words rattlin' in a gourd. Now, Matt an' me's some diff'rent. By keepin' mum fer a while, we allers hev somethin' to say whenever we talk."

"Police!" grinned Chub. "Why, Perk, you garrulous old parrot, you can talk more and say less than any man in Arizona. When'll you be around again, Matt?"

"Oh, I'll drop in on you to-morrow, some time. So-long!"

Matt returned the red roadster to McKibben's barn, where it was being kept, cleaned it up a little and made sure that everything was all right, then locked the barn door and left the key with Mrs. McKibben.

It was probably half-past four when he reached his boarding-place. As soon as he had dusted his clothes, and paid his respects to the wash-bowl, he dropped into a chair and fell to thinking, once more, about Clip, Pima Pete, and the note.

He had an idea that that note meant trouble for Clip. It was a vague sort of feeling, but strong enough to make Matt uncomfortable.

Pima Pete had been a lawbreaker, and there was a reward out for him. Being a relative of Clip's, the half-breed was safe so far as Clip and Matt were concerned, but if any one who knew Pima Pete happened to see Clip with him, there might be no end of trouble.

Thoroughly dissatisfied with the course events were taking, and not a little worried, Matt went down to supper and sat through a half hour of incessant clatter from his landlady, Mrs. Spooner. When he got up from the table he had decided to find Clip at once and get at the contents of Pima Pete's note. He went to his room after his hat, and when he opened the door there was Clip in a rocking-chair by the window. The quarter-blood had slipped into the house and up-stairs to the room while Matt had been eating his supper.

"Why, hello, old chap!" exclaimed Matt. "I was just thinking about hunting you up."
