Cuba is intersected by a range of mountains, more or less broken, which extends across the entire island, from east to west, and from which the rivers flow to the sea. This range is called the Sierra del Cobra, and it includes the Pico de Turginuo, with an altitude of 7,670 feet, the highest point on the whole island. There are other ranges, and the eastern portion of the island is particularly hilly. We must not forget the famous Pan of Matanzas which received its name from its resemblance to a loaf of sugar. It is 1,300 feet high, and has been of great service to mariners in enabling them to get their bearings. Naturally the rivers are small, but they are numerous. The principal one, and the only one that can properly be called navigable, is the Canto. Schooners ascend this for about sixty miles. It rises in the Sierra del Cobre, and empties upon the south coast, a few miles from Manzanillo. Mineral springs abound, and their medicinal qualities are in high repute. Of lakes there are only a few, and most of these lie in the marsh lands. The Scientific American says: "The country may be broadly divided into the region of the plains the rolling uplands and the forest lands. The lowlands form a practically continuous belt around the island, and in them are to be found the great sugar plantations. Above these and on the lower slopes are found the grazing and farm lands, upon, which, among other things, is raised the famous Havana tobacco. The remainder of the island, especially the eastern portion is covered with a dense forest growth." The vegetation of Cuba is of the most luxuriant and beautiful description. The forests are full of a large variety of trees, almost all of them most valuable for mechanical purposes. Some of them are almost as hard as iron. One of these is called the quiebra hacha (the axe breaker). There are other woods such as the jucaro, which are indestructible, even under water. Still others are lignum vitae, ebony, rosewood, mahogany, cedar, lancewood and many other species. There are over fifty varieties of palm, and the orange and lemon trees are indigenous. Although the forests are so dense so to be almost impenetrable, there are no wild animals in them larger than the wild dogs, which closely resemble wolves both in appearance and habits. The fruits are those natural to the tropics, but only oranges, pineapples and bananas are raised for exportation. The land is not suited to the cultivation of cereals, and there is no flour mill on the island. At one time, the coffee plantations were in a flourishing condition, but the recent outbreak has largely interfered with this industry. By far the chief industries in the island are the cultivation of sugar and tobacco, both of which are famous the world over.
