“Well, what do you find of interest?” asked Berwick, joining them, the captain following a moment later.

“We were just looking at that column of smoke over there,” replied Tom. “Do you think it is a signal of some kind?”

“What is that?” asked the captain.

“That column of smoke on the hill over there,” repeated Tom.

“Eh, what! Start my plates!” exclaimed the captain. “We will have to look into that a little later.”

“See how straight it goes up,” commented Jim. “There doesn’t seem to be a bit of air stirring.”

“Not a bit, anywhere,” assented Berwick. “Not enough for steerage way.”

“I’m thinking we’ll have all the wind we want and some to spare afore ye know it,” said the captain. “There’s a hurricane abrewing or I miss my guess.”

“What? On this clear day?” asked the professor. “I don’t see how you can tell unless you feel it in your bones.”
