knowledge very useful. He was anxious to start on the cruise immediately, but his uncle insisted that the crew must first be trained. "I must teach you to sail, and you must teach your crew to row," said Uncle John. "The Department will never consent to let a boat go on a cruise unless her commander and her crew know their duty."
"What's the Department?" asked Harry.
"The Navy Department in the United States service has the whole charge of the Navy, and sends vessels where it pleases. Now, I consider that I represent a Department of Moral Piracy, and I therefore superintend the fitting out of the Whitewing. You can't expect moral piracy to flourish unless you respect the Department, and obey its orders."
"All right, uncle," replied Harry. "Of course the Department furnishes stores and everything else for a cruise, doesn't it?"
"I suppose it must," said his uncle, laughing. "I didn't think of that when I proposed to become a department."
