“He doesn’t care a hang about us. I made no impression on him at all. The more I argued the hotter he got. He intends to carry us about with him until he has dumped his cargo of guns somewhere on the Cuban coast.

“There is some kind of a steamer astern of us,” said Van Steen to Nora Forbes. “Perhaps it is a German or English mail-boat. If so, I can see no objection to transferring us aboard.”

Captain O’Shea overheard the remark and called to them:
