"All right, pater," I replied, with the boldness acquired by my success. "I want to make a bargain with you."

"A bargain? I don't understand."

"What I mean to say is this: If you make a search for the 'San Philipo' treasure, promise me that I can go too."

"Bless the boy!" ejaculated Uncle Herbert. "What does he mean?"

"The possibility of a search is very remote," said my father, "as we have absolutely no definite information to work upon, and no likelihood of gaining any; but I really don't understand what you mean by the word 'bargain.'"

"I mean," I replied stoutly, "that if I find a key to the cipher, do I take part in the search?"

"I see no reason why you shouldn't if——"

"Then you promise?"

"Yes."

"Thanks," I replied, flourishing the paper I held in my hand.
