"If I did I didn't know it by that name," said Zeke. "What do you boys think we had better look for?"

"I say a rock shaped like a man's thumb," said Fred.

"I don't," spoke up John. "What I would look for would be a place in the mountains ahead."

"It seems to me," said Grant slowly, "that I should be on the lookout for all of them. I'm inclined to think, however, that if you find it, it's likely to be something in the shape of the ground that makes one think of a man's thumb."

"Don't none of you boys stir from this tree," ordered Zeke abruptly. "Jeff and I will go ahead and—"

"For a time you'll be the Go Ahead Boys," laughed Fred.
