Probably the best description of the topography and the orography of the island yet presented is that given by Mr. Robert T. Hill, of the United States Geological Survey. In his book on Cuba and other islands of the West Indies, Mr. Hill says:
"As regards diversity of relief, Cuba's eastern end is mountainous, with summits standing high above the adjacent sea; its middle portion is wide, consisting of gently sloping plains, well-drained, high above the sea, and broken here and there by low, forest-clad hills; and its western third is a picturesque region of mountains, with fertile slopes and valleys, of different structure and less altitude than those of the east. Over the whole is a mantle of tender vegetation, rich in every hue that a flora of more than three thousand species can give, and kept green by mists and gentle rains. Indenting the rock-bound coasts are a hundred pouch-shaped harbors such as are but rarely found in the other islands and shores of the American Mediterranean.
"But, at the outset the reader should dispossess his mind of any preconceived idea that the island of Cuba is in any sense a physical unit. On the contrary, it presents a diversity of topographic, climatic, and cultural features, which, as distributed, divide the island into at least three distinct natural provinces, for convenience termed the eastern, central, and western regions. The distinct types of relief include regions of high mountains, low hills, dissected plateaus, intermontane valleys, and coastal swamps. With the exception of a strip of the south-central coast, the island, as a whole, stands well above the sea, is thoroughly drained, and presents a rugged aspect when viewed from the sea. About one-fourth of the total area is mountainous, three-fifths are rolling plain, valleys, and gentle arable slopes, and the remainder is swampy.
"The island border on the north presents a low cliff topography, with a horizontal sky-line from Matanzas westward, gradually decreasing from five hundred feet at Matanzas to one hundred feet on the west. The coast of the east end is abrupt and rugged, presenting on both the north and south sides a series of remarkable terraces, rising in stair-like arrangement to six hundred feet or more, representing successive pauses or stages in the elevation of the island above the sea, and constituting most striking scenic features. About one-half the Cuban coast is bordered by keys, which are largely old reef rock, the creations of the same coral-builders that may now be seen through the transparent waters still at work on the modern shallows, decking the rocks and sands with their graceful and many colored tufts of animal foliage."
Mr. Hill summarizes the general appearance of the island, thus: "Santiago de Cuba (now called Oriente) is predominantly a mountainous region of high relief, especially along the coasts, with many interior valleys. Puerto Principe (now Camaguey) and Santa Clara are broken regions of low mountain relief, diversified by extensive valleys. Matanzas and Havana are vast stretches of level cultivated plain, with only a few hills of relief. Pinar del Rio is centrally mountainous, with fertile coastward slopes." The notable elevations of the island are the Cordilleras de los Organos, or Organ Mountains, in Pinar del Rio, of which an eastward extension appears in the Tetas de Managua, the Arcas de Canasi, the Escalera de Jaruco, the Pan de Matanzas, and other minor elevations in Havana and Matanzas Provinces. In Santa Clara and Camaguey, the range is represented by crest lines and plateaus along the north shore, and finally runs into the hill and mountain maze of Oriente. In the south-central section of the island, a somewhat isolated group of elevations appears, culminating in El Potrerillo at a height of nearly 3,000 feet. In Oriente, immediately along the south coast line, is the precipitous Sierra Maestra, reaching its greatest altitude in the Pico del Turquino, with an elevation of approximately 8,500 feet. Another elevation, near Santiago, known as La Gran Piedra, is estimated at 5,200 feet. All these heights are densely wooded. From the tops of some of them, east, west, and central, the views are marvellously beautiful, but the summits of most are reached only with considerable difficulty. One of the most notable of these view points, and one of the most easily reached, is the height immediately behind the city of Matanzas, overlooking the famous Yumuri valley. The valley is a broad, shallow bowl, some five or six miles in diameter, enclosed by steeply sloping walls of five to six hundred feet in height. Through it winds the Yumuri River. It is best seen in the early forenoon, or the late afternoon, when there come the shadows and the lights that are largely killed by the more vertical rays of a midday sun. At those hours, it is a scene of entrancing loveliness. There are views, elsewhere, covering wider expanses, but none, I think, of equal beauty.
The vicinity of Matanzas affords a spectacle of almost enchantment for the sight-seer, and of deep interest for the geologist. Somewhat more than fifty years ago, an accident revealed the beautiful caves of Bellamar, two or three miles from the city, and easily reached by carriage. Caves ought to be cool. These are not, but they are well worth all the perspiration it costs to see them. They are a show place, and guides are always available. In size, the caverns are not comparable with the caves of Kentucky and Virginia, but they far excel in beauty. They are about three miles in extent, and their lower levels are said to be about five hundred feet from the surface. The rock is white limestone, in which are chambers and passage-ways, stalactites and stalagmites innumerable. These have their somewhat fantastic but not unfitting names, such as the Gothic Temple, the Altar, the Guardian Spirit, the Fountain of Snow, and Columbus' Mantle. The place has been called "a dream of fairyland," a fairly appropriate description. The colors are snow-white, pink, and shades of yellow, and many of the forms are wonderfully beautiful. There are many other caves in the island, like Cotilla, in the Guines region not far from Havana, others in the Cubitas Mountains in Camaguey Province, and still others in Oriente, but in comparison with Bellamar they are little else than holes in the ground. The trip through these remarkable aisles and chambers occupies some three or four hours.
Cuba is not big enough for rivers of size. There are innumerable streams, for the island generally is well-watered. The only river of real importance is the Cauto, in Oriente Province. This is the longest and the largest river in the island. It rises in the hills north of Santiago, and winds a devious way westward for about a hundred and fifty miles, emptying at last into the Gulf of Buena Esperanza, north of the city of Manzanillo. It is navigable for small boats, according to the stage of the water, from seventy-five to a hundred miles from its mouth. Numerous smaller streams flow to the coast on both north and south. Some, that are really estuaries, are called rivers. Very few of them serve any commercial purposes. There are a few water areas called lakes, but they are really little other than ponds. On the south coast, directly opposite Matanzas, lies a vast swamp known as the Cienega de Zapata. It occupies an area of about seventy-five miles in length and about thirty miles in width, almost a dead flat, and practically at sea-level. Here and there are open spaces of water or clusters of trees, but most of it is bog and quagmire and dense mangrove thickets. Along the coast are numerous harbors, large and small, that are or, by dredging, could be made available for commercial purposes. Among these, on the north coast, from west to east, are Bahia Honda, Mariel, Havana, Matanzas, Nuevitas, Nipe Bay, and Baracoa. On the south, from east to west, are Guantanamo, Santiago, Manzanillo, Cienfuegos, and Batabano. At all of these, there are now cities or towns with trade either by steamers or small sailing vessels. Among the interesting physical curiosities of the island are the numerous "disappearing rivers." Doubtless the action of water on limestone has left, in many places, underground chambers and tunnels into which the streams have found an opening and in which they disappear, perhaps to emerge again and perhaps to find their way to the sea without reappearance. This seems to explain numerous fresh-water springs among the keys and off-shore. The Rio San Antonio quite disappears near San Antonio de los Banos. Near Guantanamo, a cascade drops three hundred feet into a cavern and reappears a short distance away. Such disappearing rivers are not unknown elsewhere but Cuba has several of them.
The Census Report of 1907, prepared under American auspices, states that "the climate of Cuba is tropical and insular. There are no extremes of heat, and there is no cold weather." This is quite true if the records of a thermometer are the standard; quite untrue if measured by the sensations of the human body. It is true that, in Havana, for instance, the thermometer seldom exceeds 90° in the hottest months, and rarely if ever goes below 50° in the coldest. But a day with the thermometer anywhere in the 80s may seem to a northern body very hot, and a day with the thermometer in the 50s is cold for anyone, whether a native or a visitor. There is doubtless a physical reason for the fact that a hot day in the north seems hotter than the same temperature in the south, while a day that seems, in the north, only pleasantly cool, seems bitterly cold in the tropics. When the thermometer drops below 60° in Havana, the coachmen blanket their horses, the people put on all the clothes they have, and all visitors who are at all sensitive to low temperature go about shivering. Steam heat and furnaces are unknown, and fireplaces are a rarity. Yet, in general, the variations are not wide, either from day to day or when measured by seasons. The extremes are the infrequent exceptions. Nor is there wide difference between day and night. Taking the island as a whole, the average mean temperature for July, the hottest month, is about 82°, and for January, the coolest month, about 71°. The mean for the year is about 77°, as compared with 52° for New York, 48° for Chicago, 62° for Los Angeles, and 68° for New Orleans. There are places that, by reason of exposure to prevailing winds, or distance from the coast, are hotter or cooler than other places. Havana is one of the cool spots, that is, relatively cool. But no one goes there in search of cold. The yearly range in Havana, from maximum to minimum, rarely if ever exceeds fifty degrees, and is usually somewhat below that, while the range in New York, Chicago, and St. Louis is usually from one hundred to one hundred and twenty-five degrees. The particular cause of discomfort for those unused to it, is the humidity that prevails throughout the greater part of the year. The worst season for this, however, is the mid-year months when few people visit the island. The winter months, locally known as the "invierno," a term to be associated with our word "vernal" and not with "infernal," are almost invariably delightful, bringing to northern systems a pleasurable physical laziness that is attended by a mental indifference to, or satisfaction with, the sensation.
