These channels are nearly of the same width, somewhat exceeding a hundred miles each, the northern passage being a few miles the broader. The Bahama Banks extend along its northern coast-line about fifty or sixty miles distant, where commences the group of many small isles known as the Bahamas, and of which we have already treated. On her eastern extreme, near Cape Maysi, Cuba is within about fifty miles of the western shore of Hayti, from which it is separated by the Windward Passage. The southern shore is washed by the Caribbean Sea, which is also here and there interspersed with small islands of little importance. One hundred and fifty miles due south lies the British island of Jamaica, with a superficial area of over four thousand square miles. Still further to the eastward, on the other side of Hayti, lies Porto Rico (like Cuba a Spanish possession), and the two groups of islands known as the Leeward and Windward isles. These are of various nationalities, including English, French, and Dutch, thus completing the entire region familiarly known to us as the West Indies.
In approaching the coast from the Windward isles, the observant traveler will notice the fields of what is called gulf-weed, which floats upon the surface of the sea. It is a unique genus, found nowhere except in these tropical waters, and must not be confounded with the sea-weed encountered by Atlantic steamers off the Banks of Newfoundland, and about the edges of the Gulf Stream in that region. This singular and interesting weed propagates itself on the waves, and there sustains, as on the shore of New Providence, zoöphytes and mollusks which also abound in these latitudes. The poetical theory relating to this sargasso, and possibly to the animals that cling to it, is that it marks the site of an Atlantic continent sunk long ages since, and that, transformed from a rooting to a floating plant, it wanders round and round as if in search of the rocks upon which it once grew. The southern shore of Cuba presents much of special interest to the conchologist in the variety and beauty of the sea-shells that abound upon its beaches. The water is of an exquisite color, a brilliant green, very changeable, like liquid opal. Were an artist truthfully to depict it, he would be called color-mad. Northern skies are never reflected in waters of such fanciful hues. Some beautiful specimens of white corals are found here, but they are not a characteristic of the coast.
On that portion bordering the Old Bahama Channel, and also opposite the Isle of Pines, which Columbus named Evangelista,—on this south shore, large numbers of turtles are taken annually, which produce the best quality of tortoise-shell. It is strange that the habits of these creatures down here in the Caribbean Sea should so closely resemble those of the tiny tortoises described by Thoreau as frequenting Walden Pond. The female turtle digs the hole in which to deposit her eggs on the sandy beach, just above the margin of high tide, generally choosing a moonlight night for the purpose. The hole is often so large that the turtle will require an hour of industrious labor to dig it to her entire satisfaction. Observing the strictest silence, the turtle-hunter steals upon the animal, and with a single motion turns it upon its back, rendering it utterly helpless, after which it can be secured at will. Thousands are annually caught in this manner.
It is a curious fact worth recalling to memory that four hundred years ago, when Columbus first landed upon the island, he found that the aborigines kept turtle corrals near the beach, amply supplied with these animals. From them they procured eggs, and also furnished themselves with the only meat which it was possible to obtain, if we except that of the little "voiceless dog" which they hunted, and such birds as they could snare. Probably as many turtles were taken by those Carib Indians in 1492 as are caught by the fishermen this year of our Lord, in the same waters, showing how inexhaustible is the supply of Neptune's kingdom. Modern epicures may not therefore claim any distinction as to the priority of discovery touching turtle soup and turtle steaks, both of which were certainly indulged in by the Caribs in Columbus' time, and probably they were in vogue many centuries previous.
One neither departs from nor approaches the Cuban shore without crossing that marvelous ocean river, the Gulf Stream, with banks and bottom of cold water, while its body and surface are warm. Its color, in the region of the gulf where it seems to have its rise, is indigo blue, so distinct that the eye can follow its line of demarkation where it joins the common waters of the sea in their prairie-green. Its surface temperature on the coast of the United States is from 75° to 80° Fahrenheit. Its current, of a uniform speed of four to five miles per hour, expends immense power in its course, and moves a body of water in the latitude of the Carolina coast fully two hundred miles wide. This aqueous body exceeds in quantity the rivers of the Mississippi and the Amazon multiplied one thousand times. Its temperature diminishes very gradually, while it moves thousands of leagues, until one branch loses itself in Arctic regions, and the other breaks on the coast of Europe. It is well known to navigators that one branch of the Gulf Stream finds its outlet northward from the Caribbean Sea through the Windward Passage, and that here the current extends to the depth of eight hundred fathoms; the width, however, in this section is not over ten miles. It will be nothing new to tell the reader that the sea, especially in its proximity to the continents, has a similar topographical conformation beneath its surface. The bottom consists of hills, mountains, and valleys, like the surface of the earth upon which we live. A practical illustration of the fact is afforded in the soundings taken by the officers of our Coast Survey in the Caribbean Sea, where a valley was found giving a water depth of three thousand fathoms, twenty-five miles south of Cuba. The Cayman islands, in that neighborhood, are the summit of mountains bordering this deep valley at the bottom of the sea. It is known to extend over seven hundred miles, from between Cuba and Jamaica nearly to the head of the bay of Honduras, with an average breadth of eighty miles. How suggestive the subject of these submarine Alps! Thus the island of Grand Cayman, scarcely twenty feet above sea level, is the top of a mountain twenty thousand five hundred and sixty-eight feet above the bottom of the submarine valley beside which it rises,—an altitude exceeding that of any mountain on the North American continent. A little more than five miles, or say twenty-seven thousand feet, is the greatest depth yet sounded at sea.
With an extensive coast-line particularly well adapted for the purpose, smuggling is at all times successfully carried on in Cuba, stimulated by an almost prohibitory tariff. It is well understood that many of the most prosperous merchants in Havana are secretly engaged in this business. The blindness of minor officials is easily purchased. The eastern department of the island is most notorious for this class of illegal trade. It was through these agencies that the revolutionists were so well supplied with arms, ammunition, and other necessities during the eight years of civil war. While we are writing these lines, the cable brings us news of a fresh landing of "filibusters" on the shores in this immediate neighborhood.
Cuba is the most westerly of the West Indian isles, and compared with the others has nearly twice as much superficial extent of territory, being about as large as England proper, without the principality of Wales. Its greatest length from east to west is very nearly eight hundred miles; its narrowest part is over twenty miles, and its average width about forty miles. The circumference of the island is set down at two thousand miles, and it is supposed to contain thirty-five thousand square miles. The face of the interior is undulating, with an average level of three hundred feet above the surface of the sea. The narrow form of the island, and the chain of mountains which divides it throughout its whole length, leave a limited course for its rivers, and consequently most of these in the rainy season become torrents, and during the rest of the year are nearly dried up. Those streams which sustain themselves at all seasons are well stocked with fine fish, and afford to lovers of the piscatory art admirable sport. Near their mouths some of the rivers, like those of the opposite coast of Florida, are frequented by crocodiles.
The chain of mountains running through the centre of the island, more or less broken in its course, is lofty in the east, but gradually diminishes in elevation towards the west, until it becomes a series of gently undulating hills of one or two hundred feet above sea level, ceasing as a connected range in the vicinity of Matanzas. On the easterly end this range of mountains approaches the south coast between Puerto Principe and Trinidad. The country lying between Cape Cruz, Cape Maysi, and the town of Holguin has the highest elevations; the most lofty point, Turquino, lately measured, has a height of ten thousand eight hundred feet. Illustrative of the great revolutions which the globe has undergone in its several geological epochs, petrified shells and bivalves are found on the summits of these highest peaks, surrounded by coral rocks, both of which differ entirely from those at present existing on the shores of the Antilles. An immense bowlder was pointed out to us on the summit of La Gran Piedra, at an elevation of five thousand feet, of totally different composition from any other rocks on the island. The great mystery is how such a mass of solid stone could have got there. Most of these mountains are thickly wooded, some of them to their very tops, and appear to be in a perpetual state of verdure. There are mahogany trees in these hills reported to be of almost fabulous dimensions, besides other trees of great age. Some idea of the excellence of the timber grown in Cuba may be had from the fact that over one hundred Spanish ships of war—some of which were of the largest size, mounting a hundred and twenty guns—have been built from native stock at the port of Havana.
Copper ore is found in abundance, as well as silver and iron, in the mountains. Snow is never known to fall even in these elevated districts, and of course in no other part of the island. In the interior, the extreme heat of the low-lying sea-coast and cities is not experienced, and the yellow fever is unknown. Low, level swampy land is found only on the southern coast, where there are some wild deer, wild cats and dogs, which are hunted; the former introduced into Cuba half a century since, the two latter descended from domestic animals. Large tracts of undulating country are without trees, affording good pasturage. In some of the mountains are extensive caves, not unlike the caves of Bellamar near the city of Matanzas, in which are still to be found the bones of an unknown race, while several of these elevations are so precipitous as to be nearly inaccessible.
Travelers who have visited the Bay of Biscay, on the French and Spanish shore near Biarritz, have observed how the rocks have been worn into caverns, arches, alcoves, and honeycombed formations by the action of the waters for centuries. Just so the soft limestone strata beneath the surface of Cuba, in many portions of the island, have been hollowed out, tunneled, and formed into caves, by the tremendous downpour and wash of tropical rains. So the action of the sea has created a cave under Moro Castle, at the mouth of the harbor of Havana, as well as under that other Moro which stands guard over the entrance of Santiago de Cuba. The existence of these subterranean caverns has often led to serious accidents. In some instances buildings which were by chance erected just over them have suddenly been swallowed up as though by an earthquake.
