"Now that's an idea," said Thorpe. He reached for a check book in his inner pocket and began to write.

"In case I lose," he explained, "I might be hard to find, so I will just ask Miss Allaire to hold this check for me. You can do the same." He handed the check to the girl.

"Winner gets his thousand back, Ruth; loser's money goes to any little orphans you happen to fancy."

"You're not serious," protested the Admiral.

"Sure! The bank will take that check seriously, I promise you. And I saw just the sloop I want for the trip ... had my eye on her for the past month."

"But, Robert," began Ruth Allaire, "you don't mean to risk your life on a foolish bet?"

Thorpe reached over to pat tenderly the hand that held his check. "I'm glad if you care," he said, and there was an undertone of seriousness beneath his raillery, "but save your sympathy for the Admiral. The U. S. Navy can't bluff me." He rose more briskly from his chair.

"Thorpe...." said Admiral Struthers. He was thinking deeply, trying to recollect. "Robert Thorpe.... I have a book by someone of that name—travel and adventure and knocking about the world. Young man, are you the Robert Thorpe?"

"Why, yes, if you wish to put it that way," agreed the other. He waved lightly to the girl as he moved away.

"I must be running along," he said, "and get that boat. See you all in San Diego!"
