"Evidently. To judge from the jumble of figures, it was the product of his poor, demented brain."

"Why, that it may not be what you think, after all. It bears the earmarks of an orderly cipher and is not scrawled at all as are the final entries in the log book."
"That's right," agreed the ensign admiringly, "you Boy Scouts have mighty keen minds. Well, my boy, keep it and study it at your leisure, although I am free to confess that I cannot think of it otherwise than in the way mentioned."
"Perhaps you are right," said Rob, "but I'll have a try at puzzling it out, when I get time."
