"Hist!" warned Clip. "Not so loud, Matt. Maybe I shouldn't have come here. But I felt as though I just had to talk with you."

Matt was "stumped." Nevertheless, he was not slow in guessing that Pima Pete's note had something to do with Clip's mysterious manner.

"What's wrong, Clip?" queried Matt, lowering his voice and setting a chair closer to his chum.

"Matter enough. You saw what happened. When the cowboy got back his horse, I mean."

"Pima Pete gave you a note."

"That's it. Not much gets away from you, Matt. I was afraid Chub and Perkins might have seen it, too."

"They didn't. I could swear to that."

"You remember what Dangerfield said when he was captured? That there was something he wanted you to do?"

Matt knitted his brows. He had not forgotten that.

"I remember it, Clip," said he; "and I remember, too, that I was to hear about the work through Pima Pete."
