“They had the same trouble here that they are having in South America,” said the professor, during the journey. “The natives do not take to the cars, no matter how low the fare. They prefer to journey on muleback or on foot, even though it takes much longer.”

“What a difference between that and our own country,” said Frank, with a laugh. “Just let a railroad lop off an hour from the running time between New York and Chicago, or between Chicago and San Francisco, and everybody runs to ride on that railroad.” And then all laughed.

“How large is Cuba?” asked Darry. “I did know, but I stored the knowledge away so carefully that I’ve forgotten where I put it.”

“Cuba is, roughly speaking, over seven hundred miles from east to west, and from fifty to a hundred miles from north to south. It contains nearly forty-four thousand square miles of territory, but a large portion of this is either very rocky, as in the mountains, or else very marshy, as along the seacoast. There is a mountain range running almost the entire length of the island. It is called the Sierra del Cobra, and boasts of one peak, the Pico de Torginno, 7,670 feet high. Besides this range of mountains there are numerous hills, particularly in the east.”

“What of the rivers?” asked Frank.

“As in Jamaica the rivers do not amount to a great deal, for the water flows directly from the mountains into the sea. There is one, called the Cauto, which empties on the south coast, just north of Manzanillo. This can be navigated by small craft for a distance of sixty miles. But there are a number of bays which make good harbors. The one at Santiago de Cuba is particularly fine.”

“Where the great fight came off, and where Hobson sunk the Merrimac!” cried Sam. “We must see that by all means. I once saw the Merrimac, but she was only a coal boat at that time.”

“The Monitor sunk the Merrimac,” came from Hockley, who was half asleep in his seat. And then as the other boys began to laugh he straightened up. “What are you laughing at anyway?” he growled. “I know I’m right.”

“We are talking about the Spanish-American War, not the Civil War,” explained the professor.

“Oh!”
