“I sure do! Cracky! I didn’t know you were such a sketch artist. This is a regular pirate’s treasure map.”

“It may turn out that way,” chuckled Rick. “I’ve been thinking about this ever since Uncle Tod gave up, and it came into my head that this may solve the mystery.”

CHAPTER XVII
ON THEIR OWN

Chot remained silent for several seconds, looking at the rough plan which Rick had sketched out. He turned it first to one side and then the other, even looking at it upside down.

“Why don’t you stand on your head?” asked Rick with a chuckling laugh. He was happy because Chot appeared to agree with his theory, or idea, which seemed wild enough at first.

“I’m trying to look at it in all sort of ways before we tackle it,” Chot said.

“Will you try it with me?” eagerly asked Rick.

“I sure will!” came the quick answer. “But aren’t you going to let your Uncle Tod in on it?”

Rick slowly shook his head.

“Not just yet,” he answered. “I want to go back to the second tunnel before I say anything, and look around, now that I have drawn out this plan. I just wanted to see what you thought of it.”
