"That ruffian"—there was mocking bitterness in Clip's voice, as he spoke—"is my uncle. He's a half-breed. His name is Pima Pete. He's one of the gang. He didn't recognize me when he rolled that stone down the hill. We haven't seen each other for two years."

Clip whirled around, as though he would make off without another word. Matt was dumfounded. He recovered himself, however, in time to call sharply:

"Clip!"

Clipperton turned and saw Matt holding out his hand. "Can't you say good-by, pard, and wish me luck?" asked Matt.

Clipperton hesitated a moment, then rushed forward, caught Matt's hand, and wrung it fervently. But he could not trust himself to speak.

Another minute and Motor Matt was in Castle Creek Cañon, headed north.
