Charlie sprang to his feet and made a stiff, military bow. “The dark gentleman over yonder,” he said solemnly, “is traveling incognito. So that you will not be confused by false appearances, I will breathe his secret. He is no less a personage than His Majesty, George the Fifth! Beside me on this couch is Mary, the Four-Fifths, and I am Herbert Hoover!—Oh, Doctor, why so angry? You may call me Herbie if you’re good!” He finished in falsetto, with rolling eyes toward Bill and Osceola.

Ruhig! Silence!” shouted the exasperated officer, while Bill and Osceola were convulsed with laughter at his fury. “Hans—take this devil-child on deck and keep him there until I come. If he offers more insolence, give him a taste of your belt!”

“Gosh, you can’t please the Doctor,” protested Charlie with an air of injured innocence as he was led forth. “He asked for the go-by, so I gave it to him.”

The stranger waved him away. “Now, you two will tell me who you are,” he commanded. “From American children one expects insolence—with you, it is different. Your names at once, if you please.”

“My name is Bolton.” Bill saw no reason for hiding his identity.

“And I,” said his friend, “am Osceola, Chief of the Seminoles.”

“So,” mused their captor. “The two young fellows that were mixed up in the Shell Island business. So!” He pronounced the last word as though it were spelled with a Z. Then for a minute or so he appeared lost in thought. Neither Bill nor Osceola uttered a word.

“So——It shall be done.” Apparently the blond man had arrived at an important decision. “I am the Baron von Hiemskirk. And remember, both of you—my word is the law. I am in command. You will earn your keep. Ja, you will be put to work and it will be well to remember that my discipline is that of the Imperial Navy. You will obey all orders—on the jump!”

“And the alternative?” Bill rose to his feet.

The baron stuck a single eyeglass in his eye and stared at Bill with an evil smile on his lips.
