The young lieutenant of engineers laughed.

"You'll be dreaming of pirates in your next watch below," he said, as he turned away, "or you'll be running up the skull and cross-bones instead of the Stars and Stripes and we'll have to court-martial you."

"Little chance of that," replied the boy, "but maybe there'll be a submarine pirate some day that we'll have a chance to chase. I'll live in hopes!"

By a somewhat curious coincidence, a few days after this conversation, the Miami passed the Dry Tortugas, the old-time capital of that Buccaneer Empire which for forty years held the navies of the entire world at bay.

On running close to the schooner the Miami learned that the bark had changed her course when the schooner approached, and when the schooner fell on her course the bark came aback again. A second time the schooner went to her relief, and again the bark squared off on her course.

The information given by the schooner proved to be startlingly correct, for a couple of hours later the lookout in the crow's-nest reported,
