"I do not know," said Dolly, glancing along the deck. "I think it is a strange place to live."

"The use of what?"

"The use of the whole thing. I know what ships are good for, of course; other ships; but what is the use of such a ship as this?"

"To take care of the other ships."

"How?"

"Have you been below? Did you see the gun decks?"

"I was in a place where there were a great many guns—but I could not understand, and there was nobody to tell me things."
