These salt water lakes or bays are often twenty-five miles or more in length by ten wide and with an average depth of fifteen feet. Unfortunately, not only are they separated by narrow passes seldom carrying over three feet, but exit to the ocean for any craft drawing over five or six feet is very difficult to find. The harbor of Nuevitas, in the northwestern corner of the Province, is one of the finest in the Island. Its width varies from three to ten miles, while its length is approximately twenty, carrying excellent deep water anchorage throughout almost its entire extent. A peculiar river-like opening, six miles in length, deep and narrow, connects it with the Atlantic Ocean. In proportion to its size, the province of Camaguey has less railroad mileage than any other in the Island. Until 1902, when Sir William Van Horn, late President of the Cuba Company, connected the City of Santa Clara by rail with Santiago de Cuba, there were but two railroads in that section of the country. One, the Camaguey & Nuevitas Road, connected the capital with practically the only shipping point on the north coast. Another, built many years before, for military purposes, connected the town of San Ferrando, on the north coast, with Jucaro on the south coast, and ran parallel with what was known as the Trocha, a military ditch about eighty kilometers in length, with two story concrete forts at each kilometer, and low dug-outs, or shooting boxes, located midway between the principal forts. The ground was cleared on either side of the railroad for a kilometer, while on both sides a perfect network of barbed wire, fastened by staples to the top of wood stakes, rendered it difficult for either infantry or cavalry to cross from one side to the other. This modern military device was established by the Spanish forces in 1895, so as to prevent the Cubans from carrying the revolution into Santa Clara and the western provinces. As in the other provinces of Cuba, cane growing and the making of sugar forms the chief industry, although, owing to the wonderfully rich potreros, or grazing lands of Camaguey, the raising of live stock in the near future will doubtless rival all other sources of wealth in that section. There are twenty sugar mills in the province with a production of approximately 3,000,000 bags. The two mills at Las Minas and Redencion, between Camaguey and Nuevitas, have been in operation for many years, but with the opening up of the Van Horn railroad a new impetus was given to sugar production, and during the past ten years, some eighteen new mills have been established at various points along the railroad where lands were fertile and comparatively cheap.
