One neither departs from nor approaches the Cuban shore without crossing that remarkable ocean-river to which we have so often referred in these pages,—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 is indigo-blue, so distinct that the eye can follow its line of demarkation where it joins the common water of the sea. Its surface temperature on the coast of the United States is from 75° to 80°. Its current, of a speed of four to five miles per hour, expends immense power in its course, and forms a body of water in the latitude of the Carolina coast fully two hundred miles wide. 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.

The sea-bottom, especially near the continents, resembles the neighboring land, and consists of hills, mountains, and valleys, like the earth upon which we live. A practical illustration of this fact is found 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 summits of mountains bordering this deep valley at the bottom of the sea, which has been found, by a series of soundings, to extend over seven hundred miles from between Cuba and Jamaica nearly to the Bay of Honduras, with an average breadth of eighty miles. Thus the island of Grand Cayman, scarcely twenty feet above sea-level, is said to be a mountain-top twenty thousand five hundred and sixty 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.

Cuba is the most westerly of the West Indian Islands, 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 fifty. The circumference is two thousand miles, and it contains over forty thousand square miles.

The nearest port of the island to this continent is Matanzas, lying due-south from Cape Sable, Florida, a distance of a hundred and thirty miles. Havana is situated some sixty miles west of Matanzas, and it is here that the island divides the entrance to the Gulf of Mexico, whose coast-line measures six thousand miles, finding the outlet for its commerce along the shore of Cuba, almost within range of the guns in Moro Castle. Lying thus at our very door, as it were, this island stands like a sentinel guarding the approaches to the Gulf of Mexico, whose waters wash the shores of five of the United States, and by virtue of the same position barring the entrance of the great river, the Mississippi, which drains half the continent of North America. So, also, Cuba keeps watch and ward over our communication with California by way of the Isthmus of Panama. It is not surprising, therefore, when we realize the commanding position of the island, that so much interest attaches to its ultimate destiny.

Matanzas is situated in one of the most fertile portions of the island, the city covering the picturesque hills by which the bay is surrounded. The fortifications are of a meagre character and could not withstand a well-directed attack for half an hour. The custom house is the most prominent building which strikes the eye on approaching the city by water. Though built of stone, it is only one story in height, and was erected at the commencement of the present century. The city is connected with Havana by railway, of which there are nearly a thousand miles in operation in the island.

Club life prevails at Matanzas, as usual at the expense of domestic or family ties; the same may be said of Havana, and both cities in this respect are like London. It is forbidden to discuss politics in these Cuban clubs, the hours being occupied mostly in playing cards, dominoes, chess, and checkers, for money. Gambling is as natural and national in Cuba as in China. Many Chinese are seen about the streets and stores of Matanzas, variously employed, and usually in a most forlorn and impoverished condition,—poor creatures who have survived their "apprenticeship" and are now free. They were brought here under the disguise of the Coolie system, as it is called, but which was only slavery in another form. These Chinese are peaceful, do not drink spirituous liquors, work hard, never meddle with politics, and live on one-half they can earn, so as to save enough to pay their passage home to their beloved land. Few succeed; eight-tenths of those imported into the island have been not only cheated out of the promised wages, but worked to death!

The famous afternoon drive and promenade of Matanzas was formerly the San Carlos Paseo. It has fine possibilities, and is lined and beautifully ornamented with thrifty Indian laurels. It overlooks the spacious harbor and outer bay, but is now entirely neglected and abandoned; even the roadway is green with vegetation, and gullied with deep hollows. It is the coolest place in the city at the evening hour, but the people have become so poor that there are hardly a dozen private vehicles in the city. Matanzas, like all the cities of Cuba, is under the shadow of depressed business, evidence of which meets one on every hand.

Havana is a thoroughly representative city, and is the centre of the talent, wealth, and population of the island. Moro Castle, with its Dahlgren guns peeping out through the yellow stones, and its tall lighthouse, stands guard over the narrow entrance of the harbor. The battery of La Punta, on the opposite shore, answers to the Moro. There are also the long range of cannon and barracks on the city side, and the massive fortress of the Cabanas crowning the hill behind the Moro. All these are decorated with the yellow flag of Spain,—the banner of gold and blood. These numerous and powerful fortifications show how important the home government regards this island, and yet modern gunnery renders these defences comparatively useless.
