"A bullet?"

"Yes," put in Matt. "It was fired from somewhere in the timber, put the motor out of business and made holes in the gas bag. We all of us had narrow escapes——"

"You look the part."

"Have you any idea who fired that shot?"

A worried expression came over Dashington's face.

"Who else but some of that sure-thing crowd?" he returned. "This boggles the situation. They know you're here, and when they find you weren't finished up out of hand they'll come looking for you. This sort of puts a crimp in our prospects, Motor Matt. Getting the sparks isn't going to be so easy. Jurgens and his crowd are over by the wagon road with an automobile, and if they think we're wise to them they may take the machine and hike."

"We've got to get back those diamonds," declared Matt.

"If we don't, I'd look pretty asking you to pull the pin on me, wouldn't I? Sure we've got to get 'em back, but——"

"Belay there, with your jaw tackle," came excitedly from Dick, in a half whisper.

He had been standing by the open door, and he suddenly drew back and hurried up to the other boys.
