Just as he had expected it was a telegraph blank, written on but not signed. It seemed to be a message that some one had started, and upon making a mistake in the wording had crammed in his pocket while he started afresh.

That some one, of course, could only be Clarence, since the paper had fallen to the ground at the time he took out his handkerchief.

Ordinarily Jack would not have been guilty of looking at a telegraph message that had come into his possession under such circumstances. It seemed excusable now.

“Glad to hear boat arrived, and is such a corker. I’m bringing that hundred with me, and hope you’ve earned it before we arrive. Don’t get in trouble for——”
