“How’s the engine, Mr. Berwick?” asked the professor of the engineer, calling down into the engine room.

“All right now, sir,” replied the engineer. “We are just going to get up steam.”

“Very good,” said the professor. “Keep it up, for we may want to start any minute. Keep your eyes on the Sea Eagle, captain, and let us know if she shows signs of getting under way.”

“Ay, ay, sir!” responded the captain.

“Feel any better now, Jo?” asked the professor, with a smile, “it is pretty near time to eat again.”

“I’m all right again now, professor,” responded Jo.

“Better get ready then, for I hear Pedro rattling the dishes down there.”

“I think”—began Tom, when they were down in their staterooms taking a washup before the noon meal.

“That it is time for dinner,” interrupted Jo.
