“All right,” said Jerry. “Let’s go!”

Once more good-bys were called, and at last the auto containing the Motor Boys and their scientist friend and Bill Cromley was on the way to Chicago. Of course this was still a long way from Thunder Mountain, but the boys were in no special hurry. The gold mine, they knew, would not run away.

“And that treasure chest has been there so long it must be rusty by this time,” remarked Bob.

“Gold doesn’t rust,” observed Ned.

“And we aren’t at all sure that we can find it,” added Jerry.

“It isn’t going to be easy,” asserted the old miner. “As I told you, many have hunted for it and never found it. But I’ll do my best to show you the spot where the coach went over. I’m glad I got out of going with that Noddy Nixon,” he added.

“He’ll make trouble for you if he can,” predicted Ned. “He was as mad as hops because we got you away from him.”

“Let him rage,” chuckled Bill Cromley. “I don’t like his kind. The more he talked the less I liked him.”

“I guess that’s about all he can do is to get mad,” Bob said.

“Don’t fool yourself, Chunky,” warned Jerry. “Noddy Nixon isn’t the kind to give up easily. We’ve had trouble with him before, and we may have again.”
