“ The extreme length of Pinar del Rio, from southwest to northeast, in a straight line, is nearly two hundred miles, while its average width is fifty. The rivers and streams all have their sources in the central divide, and flow to the north and south, emptying into the Gulf of Mexico and the Caribbean Sea. None of these, of course, are available for navigation more than a few miles up from their mouths, and while serving as drainage streams during the rainy season, many of them, unfortunately, cease to flow during the dry months of February and March. ”
