“It would be much more interesting than going out to sea,” put in Jack. “It’s so much better than having to be always looking through a glass.”

“Try inside, Bradleigh,” said Sir John.

“It means coals, sir.”

“Never mind that,” said Sir John, who had just drawn a deep breath full of satisfaction to see the intense interest his son was taking in everything now.
