“I guess captains often take the law into their own hands,” said Darry. “They can put in a complaint of mutiny, or something like that, and a sailor, or other ship’s hand, has no show.”

The day had started in bright and clear, but by ten o’clock it began to grow misty, and soon a drizzling rain was falling and they were compelled to seek the shelter of the cabin.

“I think we may as well improve our time by having a talk about Jamaica,” said Professor Strong. “We shall only stop for one day at Kingston—unless something unforeseen happens—but it won’t hurt to know something of this English possession.”

He had his map handy, and placing it on the wall he sat down in front of it, and the boys ranged close alongside.

“As you can readily see,” began the professor, “Jamaica is an island located in the Caribbean Sea directly north of Colombia in South America and south of the island of Cuba. It is oval in shape and is about one hundred and fifty miles long by fifty miles wide. Can any of you name a State at home of about that size?”

There was a few seconds of silence.

“If I am not mistaken New Jersey is just a little larger than that,” answered Mark.

“You are right Robertson, the general length and the general width are about the same, although New Jersey contains more square miles than Jamaica. The island has a ridge of high hills running east and west, called the Blue Mountains, and from these hills spring over half a dozen small streams which flow into the sea.”

“Can you sail on the rivers?” came from Darry.

“On only a few, Crane, the others contain too many rapids and waterfalls. The deepest stream is the Black River, which is used by small boats for perhaps twenty-five or thirty miles. I once had an adventure on that river, so I am not likely to forget it.”
