know it," Thorpe agreed, "but I saw them—a stretch of white water for an eighth of a mile. I know it's impossible, but true. But forget that item for a time, Admiral. Look at this." He opened a brief case and took out a log-book and some other papers.

"The log of the Minnie R.," he explained briefly. "Nothing in it but routine entries up to that morning and then nothing at all."

"Abandoned," mused the Admiral, "and they did not take to the boats. There have been other instances—never explained."

"See if this helps any," suggested Thorpe and handed the other two sheets of paper. "They were in the captain's cabin," he added.

Admiral Struthers glanced at them, then settled back in his chair.

"Dated September fourth," he said. "That would have been the day previous to the time you found her." The writing was plain, in a careful, well-formed hand. He cleared his throat and read aloud:

"Written by Jeremiah Wilkens of Salem, Mass., master of the Minnie R., bound from Shanghai to San Pedro. I have sailed the seas for forty years, and for the first time I am afraid. I hope I may destroy this paper when the lights of San Pedro are safe in sight, but I am writing here what it would shame me to set down in the ship's log, though I know there are stranger happenings on the face of the waters than man has ever seen—or has lived to tell.
