already spoken to our captain, Jack Benson, about this matter."

"Ach! Yes."

"And Jack has refused."

"Your captain is a fool!" cried the German.

"Then we serve a fool, because he's our captain," retorted Hal, quietly,
though there was a flash in his eyes.

"I shall look for you two at the hotel in one hour," declared the German,
impressively.

"My friend, Mr. Somers, has already told you that you'll be using your
eyesight to poor advantage, then," Hal answered.

"What do you mean?"

"Why, I mean, Professor, that you can't possibly persuade us to go to
Germany and tell your people anything that we know about the Pollard
submarine boats, or any other type."

"But you shall be well paid!"

"Professor, what would be your price for selling out your country to the
United States?" asked Hal, gazing fixedly at the German.

"You insult me!" cried the German, his face growing red. "I am a
patriot."
