POLITICAL ESSAY ON THE ISLAND OF CUBA. THE HAVANNAH. HILLS OF GUANAVACOA, CONSIDERED IN THEIR GEOLOGICAL RELATIONS. VALLEY OF LOS GUINES, BATABANO, AND PORT OF TRINIDAD. THE KING AND QUEEN’S GARDENS.

Cuba owes its political importance to a variety of circumstances, among which may be enumerated the extent of its surface, the fertility of its soil, its naval establishments, and the nature of its population, of which three-fifths are free men. All these advantages are heightened by the admirable position of the Havannah. The northern part of the Caribbean Sea, known by the name of the Gulf of Mexico, forms a circular basin more than two hundred and fifty leagues in diameter: it is a Mediterranean with two outlets. The island of Cuba, or rather its coast between Cape St. Antonio and the town of Matanzas, situated at the opening of the old channel, closes the Gulf of Mexico on the south-east, leaving the ocean current known by the name of the Gulf Stream, no other outlet on the south than a strait between Cape St. Antonio and Cape Catoche; and no other on the north than the channel of Bahama, between Bahia–Honda and the shoals of Florida. Near the northern outlet, where the highways of so many nations may be said to cross each other, lies the fine port of the Havannah, fortified at once by nature and by art. The fleets which sail from this port and which are partly constructed of the cedrela and the mahogany of the island of Cuba, might, at the entrance of the Mexican Mediterranean, menace the opposite coast, as the fleets that sail from Cadiz command the Atlantic near the Pillars of Hercules. In the meridian of the Havannah the Gulf of Mexico, the old channel, and the channel of Bahama unite. The opposite direction of the currents and the violent agitations of the atmosphere at the setting-in of winter impart a peculiar character to these latitudes at the extreme limit of the equinoctial zone.

The island of Cuba is the largest of the Antilles.* Its long and narrow form gives it a vast development of coast and places it in proximity with Hayti and Jamaica, with the most southern province of the United States (Florida) and the most easterly province of the Mexican Confederation (Yucatan).* This circumstance claims serious attention when it is considered that Jamaica, St. Domingo, Cuba and the southern parts of the United States (from Louisiana to Virginia) contain nearly two million eight hundred thousand Africans. Since the separation of St. Domingo, the Floridas and New Spain from the mother-country, the island of Cuba is connected only by similarity of religion, language and manners with the neighbouring countries, which, during ages, were subject to the same laws.

[* Its area is little less in extent than that of England not including Wales.]

[* These places are brought into communication one with another by a voyage of ten or twelve days.]

Florida forms the last link in that long chain, the northern extremity of which reaches the basin of St. Lawrence and extends from the region of palm-trees to that of the most rigorous winter. The inhabitant of New England regards the increasing augmentation of the black population, the preponderance of the slave states and the predilection for the cultivation of colonial products as a public danger; and earnestly wishes that the strait of Florida, the present limit of the great American confederation, may never be passed but with the views of free trade, founded on equal rights. If he fears events which may place the Havannah under the dominion of a European power more formidable than Spain, he is not the less desirous that the political ties by which Louisiana, Pensacola and Saint Augustin of Florida were heretofore united to the island of Cuba may for ever be broken.

The extreme sterility of the soil, joined to the want of inhabitants and of cultivation, have at all times rendered the proximity of Florida of small importance to the trade of the Havannah; but the case is different on the coast of Mexico. The shores of that country, stretching in a semicircle from the frequented ports of Tampico, Vera Cruz, and Alvarado to Cape Catoche, almost touch, by the peninsula of Yucatan, the western part of the island of Cuba. Commerce is extremely active between the Havannah and the port of Campeachy; and it increases, notwithstanding the new order of things in Mexico, because the trade, equally illicit with a more distant coast, that of Caracas or Columbia, employs but a small number of vessels. In such difficult times the supply of salt meat (tasajo) for the slaves is more easily obtained from Buenos Ayres and the plains of Merida than from those of Cumana, Barcelona and Caracas. The island of Cuba and the archipelago of the Philippines have for ages derived from New Spain the funds necessary for their internal administration and for keeping up their fortifications, arsenals and dockyards. The Havannah was the military port of the New World; and, till 1808, annually received 1,800,000 piastres from the Mexican treasury. At Madrid it was long the custom to consider the island of Cuba and the archipelago of the Philippines as dependencies on Mexico, situated at very unequal distances east and west of Vera Cruz and Acapulco, but linked to the Mexican metropolis (then a European colony) by all the ties of commerce, mutual aid and ancient sympathies. Increased internal wealth has rendered unnecessary the pecuniary succour formerly furnished to Cuba from the Mexican treasury. Of all the Spanish possessions that island has been most prosperous: the port of the Havannah has, since the troubles of St. Domingo, become one of the most important points of the commercial world. A fortunate concurrence of political circumstances, joined to the intelligence and commercial activity of the inhabitants, have preserved to the Havannah the uninterrupted enjoyment of free intercourse with foreign nations.

I twice visited this island, residing there on one occasion for three months, and on the other for six weeks; and I enjoyed the confidence of persons who, from their abilities and their position, were enabled to furnish me with the best information. In company with M. Bonpland I visited only the vicinity of the Havannah, the beautiful valley of Guines and the coast between Batabano and the port of Trinidad. After having succinctly described the aspect of this scenery and the singular modifications of a climate so different from that of the other islands, I will proceed to examine the general population of the Island of Cuba; its area calculated from the most accurate sketch of the coast; the objects of trade and the state of the public revenue.

The aspect of the Havannah, at the entrance of the port, is one of the gayest and most picturesque on the shore of equinoctial America north of the equator. This spot is celebrated by travellers of all nations. It boasts not the luxuriant vegetation that adorns the banks of the river Guayaquil nor the wild majesty of the rocky coast of Rio de Janeiro; but the grace which in those climates embellishes the scenes of cultivated nature is at the Havannah mingled with the majesty of vegetable forms and the organic vigour that characterizes the torrid zone. On entering the port of the Havannah you pass between the fortress of the Morro (Castillo de los Santos Reyes) and the fort of San Salvador de la Punta: the opening being only from one hundred and seventy to two hundred toises wide. Having passed this narrow entrance, leaving on the north the fine castle of San Carlos de la Cabana and the Casa Blanca, we reach a basin in the form of a trefoil of which the great axis, stretching from south-south-west to north-north-east, is two miles and one-fifth long. This basin communicates with three creeks, those of Regla, Guanavacoa and Atares; in this last there are some springs of fresh water. The town of the Havannah, surrounded by walls, forms a promontory bounded on the south by the arsenal and on the north by the fort of La Punta. After passing beyond some wrecks of vessels sunk in the shoals of La Luz, we no longer find eight or ten, but five or six fathoms of water. The castles of Santo Domingo de Atares and San Carlos del Principe defend the town on the westward; they are distant from the interior wall, on the land side, the one 660 toises, the other 1240. The intermediate space is filled by the suburbs (arrabales or barrios extra muros) of the Horcon, Jesu–Maria, Guadaloupe and Senor de la Salud, which from year to year encroach on the Field of Mars (Campo de Marte). The great edifices of the Havannah, the cathedral, the Casa del Govierno, the house of the commandant of the marine, the Correo or General Post Office and the factory of Tobacco are less remarkable for beauty than for solidity of structure. The streets are for the most part narrow and unpaved. Stones being brought from Vera Cruz, and very difficult of transport, the idea was conceived a short time before my voyage of joining great trunks of trees together, as is done in Germany and Russia, when dykes are constructed across marshy places. This project was soon abandoned and travellers newly arrived beheld with surprise fine trunks of mahogany sunk in the mud of the Havannah. At the time of my sojourn there few towns of Spanish America presented, owing to the want of a good police, a more unpleasant aspect. People walked in mud up to the knee; and the multitude of caleches or volantes (the characteristic equipage of the Havannah) of carts loaded with casks of sugar, and porters elbowing passengers, rendered walking most disagreeable. The smell of tasajo often poisons the houses and the winding streets. But it appears that of late the police has interposed and that a manifest improvement has taken place in the cleanliness of the streets; that the houses are more airy and that the Calle de los Mercadores presents a fine appearance. Here, as in the oldest towns of Europe. an ill-traced plan of streets can only be amended by slow degrees.

There are two fine public walks; one called the Alameda, between the hospital of Santa Paula and the theatre, and the other between the Castillo de la Punta and the Puerta de la Muralla, called the Paseo extra muros; the latter is deliciously cool and is frequented by carriages after sunset. It was begun by the Marquis de la Torre, governor of the island, who gave the first impulse to the improvement of the police and the municipal government. Don Luis de las Casas and the Count de Santa Clara enlarged the plantations. Near the Campo de Marte is the Botanical Garden which is well worthy to fix the attention of the government; and another place fitted to excite at once pity and indignation — the barracoon, in front of which the wretched slaves are exposed for sale. A marble statue of Charles III has been erected since my return to Europe, in the extra muros walk. This spot was at first destined for a monument to Christopher Columbus whose ashes, after the cession of the Spanish part of St. Domingo, were brought to the island of Cuba.*

[* Columbus lies buried in the cathedral of the Havannah, close to the wall near the high altar. On the tomb is the following inscription:

O restos y Imagen del grande Colon;
Mil siglos duran guardados en la Urna,
Y en remembranca de nuestra Nacion.

Oh relics and image of the great Colon (Columbus)
A thousand ages are encompassed in thy Urn,
And in the memory of our Nation.

His remains were first deposited at Valladolid and thence were removed to Seville. In 1536 the bodies of Columbus and of his son Diego (El Adelantado) were carried to St. Domingo and there interred in the cathedral; but they were afterwards removed to the place where they now repose.]

The same year the ashes of Fernando Cortez were transferred in Mexico from one church to another: thus, at the close of the eighteenth century, the remains of the two greatest men who promoted the conquest of America were interred in new sepulchres.

The most majestic palm-tree of its tribe, the palma real, imparts a peculiar character to the landscape in the vicinity of the Havannah; it is the Oreodoxa regia of our description of American palm-trees. Its tall trunk, slightly swelled towards the middle, grows to the height of 60 or 80 feet; the upper part is glossy, of a delicate green, newly formed by the closing and dilatation of the petioles, contrasts with the rest, which is whitish and fendilated. It appears like two columns, the one surmounting the other. The palma real of the island of Cuba has feathery leaves rising perpendicularly towards the sky, and curved only at the point. The form of this plant reminded us of the vadgiai palm-tree which covers the rocks in the cataracts of the Orinoco, balancing its long points over a mist of foam. Here, as in every place where the population is concentrated, vegetation diminishes. Those palm-trees round the Havannah and in the amphitheatre of Regla on which I delighted to gaze are disappearing by degrees. The marshy places which I saw covered with bamboos are cultivated and drained. Civilization advances; and the soil, gradually stripped of plants, scarcely offers any trace of its wild abundance. From the Punta to San Lazaro, from Cabana to Regla and from Regla to Atares the road is covered with houses, and those that surround the bay are of light and elegant construction. The plan of these houses is traced out by the owners, and they are ordered from the United States, like pieces of furniture. When the yellow fever rages at the Havannah the proprietors withdraw to those country houses and to the hills between Regla and Guanavacoa to breathe a purer air. In the coolness of night, when the boats cross the bay, and owing to the phosphorescence of the water, leave behind them long tracks of light, these romantic scenes afford charming and peaceful retreats for those who wish to withdraw from the tumult of a populous city. To judge of the progress of cultivation travellers should visit the small plots of maize and other alimentary plants, the rows of pine-apples (ananas) in the fields of Cruz de Piedra and the bishop’s garden (Quinta del Obispo) which of late is become a delicious spot.

The town of the Havannah, properly so called, surrounded by walls, is only 900 toises long and 500 broad; yet more than 44,000 inhabitants, of whom 26,000 are negroes and mulattoes, are crowded together in this narrow space. A population nearly as considerable occupies the two great suburbs of Jesu–Maria and La Salud.* The latter place does not verify the name it bears; the temperature of the air is indeed lower than in the city but the streets might have been larger and better planned. Spanish engineers, who have been waging war for thirty years past with the inhabitants of the suburbs (arrabales), have convinced the government that the houses are too near the fortifications, and that the enemy might establish himself there with impunity. But the government has not courage to demolish the suburbs and disperse a population of 28,000 inhabitants collected in La Salud only. Since the great fire of 1802 that quarter has been considerably enlarged; barracks were at first constructed, but by degrees they have been converted into private houses. The defence of the Havannah on the west is of the highest importance: so long as the besieged are masters of the town, properly so called, and of the southern part of the bay, the Morro and La Cabana, they are impregnable because they can be provisioned by the Havannah, and the losses of the garrison repaired. I have heard well-informed French engineers observe that an enemy should begin his operations by taking the town, in order to bombard the Cabana, a strong fortress, but where the garrison, shut up in the casemates, could not long resist the insalubrity of the climate. The English took the Morro without being masters of the Havannah; but the Cabana and the Fort Number 4 which commands the Morro did not then exist. The most important works on the south and west are the Castillos de Atares y del Principe, and the battery of Santa Clara.

[* Salud signifies Health.]

We employed the months of December, January and February in making observations in the vicinity of the Havannah and the fine plains of Guines. We experienced, in the family of Senor Cuesta (who then formed with Senor Santa Maria one of the greatest commercial houses in America) and in the house of Count O’Reilly, the most generous hospitality. We lived with the former and deposited our collections and instruments in the spacious hotel of Count O’Reilly, where the terraces favoured our astronomical observations. The longitude of the Havannah was at this period more than one fifth of a degree uncertain.* It had been fixed by M. Espinosa, the learned director of the Deposito hidrografico of Madrid, at 5° 38′ 11″, in a table of positions which he communicated to me on leaving Madrid. M. de Churruca fixed the Morro at 5 hours 39 minutes 1 second. I met at the Havannah with one of the most able officers of the Spanish navy, Captain Don Dionisio Galeano, who had taken a survey of the coast of the strait of Magellan. We made observations together on a series of eclipses of the satellites of Jupiter, of which the mean result gave 5 hours 38 minutes 50 seconds. M. Oltmanns deduced in 1805 the whole of those observations which I marked for the Morro, at 5 hours 38 minutes 52.5 seconds — 84° 43′ 7.5 seconds west of the meridian of Paris. This longitude was confirmed by fifteen occultations of stars observed from 1809 to 1811 and calculated by M. Ferrer: that excellent observer fixes the definitive result at 5° 38′ 50.9 seconds. With respect to the magnetic dip I found it by the compass of Borda (December 1800) 53° 22′ of the old sexagesimal division: twenty-two years before, according to the very accurate observations made by Captain Sabine in his memorable voyage to the coasts of Africa, America and Spitzbergen, the dip was only 51° 55′; it had therefore diminished 1 degree 27 minutes.

[* I also fixed, by direct observations, several positions in the interior of the island of Cuba: namely Rio Blanco, a plantation of Count Jaruco y Mopex; the Almirante, a plantation of the Countess Buenavista; San Antonio de Beitia; the village of Managua; San Antonio de Bareto; and the Fondadero, near the town of San Antonio de los Banos.]

The island of Cuba being surrounded with shoals and breakers along more than two-thirds of its length, and as ships keep out beyond those dangers, the real shape of the island was for a long time unknown. Its breadth, especially between the Havannah and the port of Batabano, has been exaggerated; and it is only since the Deposito hidrografico of Madrid published the observations of captain Don Jose del Rio, and lieutenant Don Ventura de Barcaiztegui, that the area of the island of Cuba could be calculated with any accuracy. Wishing to furnish in this work the most accurate result that can be obtained in the present state of our astronomical knowledge, I engaged M. Bauza to calculate the area. He found, in June, 1835, the surface of the island of Cuba, without the Isla dos Pinos, to be 3520 square sea leagues, and with that island 3615. From this calculation, which has been twice repeated, it results that the island of Cuba is one-seventh less than has hitherto been believed; that it is 32/100 larger than Hayti, or San Domingo; that its surface equals that of Portugal, and within one-eighth that of England without Wales; and that if the whole archipelago of the Antilles presents as great an area as the half of Spain, the island of Cuba alone almost equals in surface the other Great and Small Antilles. Its greatest length, from Cape San Antonio to Point Maysi (in a direction from west-south-west to east-north-east and from west-north-west to east-south-east) is 227 leagues; and its greatest breadth (in the direction north and south), from Point Maternillo to the mouth of the Magdalena, near Peak Tarquino, is 37 leagues. The mean breadth of the island, on four-fifths of its length, between the Havannah and Puerto Principe, is 15 leagues. In the best cultivated part, between the Havannah and Batabano, the isthmus is only eight sea leagues. Among the great islands of the globe, that of Java most resembles the island of Cuba in its form and area (4170 square leagues). Cuba has a circumference of coast of 520 leagues, of which 280 belong to the south shore, between Cape San Antonio and Punta Maysi.

The island of Cuba, over more than four-fifths of its surface, is composed of low lands. The soil is covered with secondary and tertiary formations, formed by some rocks of gneiss-granite, syenite and euphotide. The knowledge obtained hitherto of the geologic configuration of the country, is as unsatisfactory as what is known respecting the relative age and nature of the soil. It is only ascertained that the highest group of mountains lies at the south-eastern extremity of the island, between Cape Cruz, Punta Maysi, and Holguin. This mountainous part, called the Sierra or Las Montanas del Cobre (the Copper Mountains), situated north-west of the town of Santiago de Cuba, appears to be about 1200 toises in height. If this calculation be correct, the summits of the Sierra would command those of the Blue Mountains of Jamaica, and the peaks of La Selle and La Hotte in the island of San Domingo. The Sierra of Tarquino, fifty miles west of the town of Cuba, belongs to the same group as the Copper Mountains. The island is crossed from east-south-east to west-north-west by a chain of hills, which approach the southern coast between the meridians of La Ciudad de Puerto Principe and the Villa Clara; while, further to the westward towards Alvarez and Matanzas, they stretch in the direction of the northern coast. Proceeding from the mouth of the Rio Guaurabo to the Villa de la Trinidad, I saw on the north-west, the Lomas de San Juan, which form needles or horns more than 300 toises high, with their declivities sloping regularly to the south. This calcareous group presents a majestic aspect, as seen from the anchorage near the Cayo de Piedras. Xagua and Batabano are low coasts; and I believe that, in general, west of the meridian of Matanzas, there is no hill more than 200 toises high, with the exception of the Pan de Guaixabon. The land in the interior of the island is gently undulated, as in England; and it rises only from 45 to 50 toises above the level of the sea. The objects most visible at a distance, and most celebrated by navigators, are the Pan de Matanzas, a truncated cone which has the form of a small monument; the Arcos de Canasi, which appear between Puerto Escondido and Jaruco, like small segments of a circle; the Mesa de Mariel, the Tetas de Managua, and the Pan de Guaixabon. This gradual slope of the limestone formations of the island of Cuba towards the north and west indicates the submarine connection of those rocks with the equally low lands of the Bahama Islands, Florida and Yucatan.

Intellectual cultivation and improvement were so long restricted to the Havannah and the neighbouring districts, that we cannot be surprised at the ignorance prevailing among the inhabitants respecting the geologic formation of the Copper Mountains. Don Francisco Ramirez, a traveller versed in chemical and mineralogical science, informed me that the western part of the island is granitic, and that he there observed gneiss and primitive slate. Probably the alluvial deposits of auriferous sand which were explored with much ardour* at the beginning of the conquest, to the great misfortune of the natives came from those granitic formations; traces of that sand are still found in the rivers Holguin and Escambray, known in general in the vicinity of Villa–Clara, Santo Espiritu, Puerto del Principe de Bayamo and the Bahia de Nipe. The abundance of copper mentioned by the Conquistadores of the sixteenth century, at a period when the Spaniards were more attentive than they have been in latter times to the natural productions of America, may possibly be attributed to the formations of amphibolic slate, transition clay-slate mixed with diorite, and to euphotides analogous to those I found in the mountains of Guanabacoa.

[* At Cubanacan, that is, in the interior of the island, near Jagua and Trinidad, where the auriferous sands have been washed by the waters as far as the limestone soil. Martyr d’Anghiera, the most intelligent writer on the Conquest, says: “Cuba is richer in gold than Hispaniola (San Domingo); and at the moment I am writing, 180,000 castillanos of ore have been collected at Cuba.” Herrera estimates the tax called King’s-fifth (quinto del Rey), in the island of Cuba, at 6000 pesos, which indicates an annual product of 2000 marks of gold, at 22 carats; and consequently purer than the gold of Sibao in San Domingo. In 1804 the mines of Mexico altogether produced 7000 marks of gold; and those of Peru 3400. It is difficult, in these calculations, to distinguish between the gold sent to Spain by the first Conquistadores, that obtained by washings, and that which had been accumulated for ages in the hands of the natives, who were pillaged at will. Supposing that in the two islands of Cuba and San Domingo (in Cubanacan and Cibao) the product of the washings was 3000 marks of gold, we find a quantity three times less than the gold furnished annually (1790 to 1805) by the small province of Choco. In this supposition of ancient wealth there is nothing improbable; and if we are surprised at the scanty produce of the gold-washings attempted in our days at Cuba and San Domingo, which were heretofore so prolific, it must be recollected that at Brazil also the product of the gold-washings has fallen, from 1760 to 1820, from 6600 gold kilogrammes to less than 595. Lumps of gold weighing several pounds, found in our days in Florida and North and South Carolina, prove the primitive wealth of the whole basin of the Antilles from the island of Cuba to the Appalachian chain. It is also natural that the product of the gold-washings should diminish with greater rapidity than that of the subterraneous working of the veins. The metals not being renewed in the clefts of the veins (by sublimation) now accumulate in alluvial soil by the course of the rivers where the table-lands are higher than the level of the surrounding running waters. But in rocks with metalliferous veins the miner does not at once know all he has to work. He may chance to lengthen the labours, to go deep, and to cross other accompanying veins. Alluvial soils are generally of small depth where they are auriferous; they most frequently rest upon sterile rocks. Their superficial position and uniformity of composition help to the knowledge of their limits, and wherever workmen can be collected, and where the waters for the washings abound, accelerate the total working of the auriferous clay. These considerations, suggested by the history of the Conquest, and by the science of mining, may throw some light on the problem of the metallic wealth of Hayti. In that island, as well as at Brazil, it would be more profitable to attempt subterraneous workings (on veins) in primitive and intermediary soils than to renew the gold-washings which were abandoned in the ages of barbarism, rapine and carnage.]

The central and western parts of the island contain two formations of compact limestone; one of clayey sandstone and another of gypsum. The former has, in its aspect and composition, some resemblance to the Jura formation. It is white, or of a clear ochre-yellow, with a dull fracture, sometimes conchoidal, sometimes smooth; divided into thin layers, furnishing some balls of pyromac silex, often hollow (at Rio Canimar two leagues east of Matanzas), and petrifications of pecten, cardites, terebratules and madrepores.* I found no oolitic beds, but porous beds almost bulbous, between the Potrero del Conde de Mopox, and the port of Batabano, resembling the spongy beds of Jura limestone in Franconia, near Dondorf, Pegnitz, and Tumbach. Yellowish cavernous strata, with cavities from three to four inches in diameter, alternate with strata altogether compact,* and poorer in petrifications. The chain of hills that borders the plain of Guines on the north and is linked with the Lomas de Camua, and the Tetas de Managua, belongs to the latter variety, which is reddish white, and almost of lithographic nature, like the Jura limestone of Pappenheim. The compact and cavernous beds contain nests of brown ochreous iron; possibly the red earth (tierra colorada) so much sought for by the coffee planters (haciendados) owes its origin to the decomposition of some superficial beds of oxidated iron, mixed with silex and clay, or to a reddish sandstone* superposed on limestone. The whole of this formation, which I shall designate by the name of the limestone of Guines, to distinguish it from another much more recent, forms, near Trinidad, in the Lomas of St. Juan, steep declivities, resembling the mountains of limestone of Caripe, in the vicinity of Cumana. They also contain great caverns, near Matanzas and Jaruco, where I have not heard that any fossil bones have been found. The frequency of caverns in which the pluvial waters accumulate, and where small rivers disappear, sometimes causes a sinking of the earth. I am of opinion that the gypsum of the island of Cuba belongs not to tertiary but to secondary soil; it is worked in several places on the east of Matanzas, at San Antonio de los Banos, where it contains sulphur, and at the Cayos, opposite San Juan de los Remedios. We must not confound with this limestone of Guines, sometimes porous, sometimes compact, another formation so recent that it seems to augment in our days. I allude to the calcareous agglomerates, which I saw in the islands of Cayos that border the coast between the Batabano and the bay of Xagua, principally south of the Cienega de Zapata, Cayo Buenito, Cayo Flamenco and Cayo de Piedras. The soundings prove that they are rocks rising abruptly from a bottom of between twenty and thirty fathoms. Some are at the water’s edge, others one-fourth or one-fifth of a toise above the surface of the sea. Angular fragments of madrepores, and cellularia from two to three cubic inches, are found cemented by grains of quartzose sand. The inequalities of the rocks are covered by mould, in which, by help of a microscope, we only distinguish the detritus of shells and corals. This tertiary formation no doubt belongs to that of the coast of Cumana, Carthagena, and the Great Land of Guadaloupe, noticed in my geognostic table of South America.* MM. Chamiso and Guiamard have recently thrown great light on the formation of the coral islands in the Pacific. At the foot of the Castillo de in Punta, near the Havannah, on shelves of cavernous rocks,* covered with verdant sea-weeds and living polypi, we find enormous masses of madrepores and other lithophyte corals set in the texture of those shelves. We are at first tempted to admit that the whole of this limestone rock, which constitutes the principal portion of the island of Cuba, may be traced to an uninterrupted operation of nature — to the action of productive organic forces — an action which continues in our days in the bosom of the ocean; but this apparent novelty of limestone formations soon vanishes when we quit the shore, and recollect the series of coral rocks which contain the formations of different ages, the muschelkalk, the Jura limestone and coarse limestone. The same coral rocks as those of the Castillo and La Punta are found in the lofty inland mountains, accompanied with petrifications of bivalve shells, very different from those now seen on the coasts of the Antilles. Without positively assigning a determinate place in the table of formations to the limestone of Guines, which is that of the Castillo and La Punta, I have no doubt of the relative antiquity of that rock with respect to the calcareous agglomerate of the Cayos, situated south of Batabano, and east of the island of Pinos. The globe has undergone great revolutions between the periods when these two soils were formed; the one containing the great caverns of Matanzas, the other daily augmenting by the agglutination of fragments of coral and quartzose sand. On the south of the island of Cuba, the latter soil seems to repose sometimes on the Jura limestone of Guines, as in the Jardinillos, and sometimes (towards Cape Cruz) immediately over primitive rocks. In the lesser Antilles the corals are covered with volcanic productions. Several of the Cayos of the island of Cuba contain fresh water; and I found this water very good in the middle of the Cayo de Piedras. When we reflect on the extreme smallness of these islands we can scarcely believe that the fresh-water wells are filled with rain-water not evaporated. Do they prove a submarine communication between the limestone of the coast with the limestone serving as the basis of lithophyte polypi, and is the fresh water of Cuba raised up by hydrostatic pressure across the coral rocks of Cayos, as it is in the bay of Xagua, where, in the middle of the sea, it forms springs frequented by the lamantins?

[* I saw neither gryphites nor ammonites of Jura limestone nor the nummulites and cerites of coarse limestone.]

[* The western part of the island has no deep ravines; and we recognize this alternation in travelling from the Havannah to Batabano, the deepest beds (inclined from 30 to 40° north-east) appear as we advance.]

[* Sandstone and ferruginous sand; iron-sand?]

[* M. Moreau de Jonnes has well distinguished, in his Histoire physique des Antilles Francoises, between the Roche a ravets of Martinique and Hayti, which is porous, filled with terebratulites, and other vestiges of sea-shells, somewhat analogous to the limestone of Guines and the calcareous pelagic sediment called at Guadaloupe Platine, or Maconne bon Dieu. In the cayos of the island of Cuba, or Jardinillos del Rey y del Reyna, the whole coral rock lying above the surface of the water appeared to me to be fragmentary, that is, composed of broken blocks. It is, however, probable, that in the depth it reposes on masses of polypi still living.]

[* The surface of these shelves, blackened and excavated by the waters, presents ramifications like the cauliflower, as they are observed on the currents of lava. Is the change of colour produced by the waters owing to the manganese which we recognize by some dendrites? The sea, entering into the clefts of the rocks, and in a cavern at the foot of the Castillo del Morro, compresses the air and makes it issue with a tremendous noise. This noise explains the phenomena of the baxos roncadores (snoring bocabeoos), so well known to navigators who cross from Jamaica to the mouth of Rio San Juan of Nicaragua, or to the island of San Andres.]

The secondary formations on the east of the Havannah are pierced in a singular manner by syenitic and euphotide rocks united in groups. The southern bottom of the bay as well as the northern part (the hills of the Morro and the Cabana) are of Jura limestone; but on the eastern bank of the two Ensenadas de Regla and Guanabacoa, the whole is transition soil. Going from north to south, and first near Marimelena, we find syenite consisting of a great quantity of hornblende, partly decomposed, a little quartz, and a reddish-white feldspar seldom crystallized. This fine syenite, the strata of which incline to the north-west, alternates twice with serpentine. The layers of intercalated serpentine are three toises thick. Farther south, towards Regla and Guanabacoa, the syenite disappears, and the whole soil is covered with serpentine, rising in hills from thirty to forty toises high, and running from east to west. This rock is much fendillated, externally of a bluish-grey, covered with dendrites of manganese, and internally of leek and asparagus-green, crossed by small veins of asbestos. It contains no garnet or amphibole, but metalloid diallage disseminated in the mass. The serpentine is sometimes of an esquillous, sometimes of a conchoidal fracture: this was the first time I had found metalloid diallage within the tropics. Several blocks of serpentine have magnetic poles; others are of such a homogeneous texture, and have such a glossiness, that at a distance they may be taken for pechstein (resinite). It were to be wished that these fine masses were employed in the arts as they are in several parts of Germany. In approaching Guanabacoa we find serpentine crossed by veins between twelve and fourteen inches thick, and filled with fibrous quartz, amethyst, and fine mammelonnes, and stalactiforme chalcedonies; it is possible that chrysoprase may also one day be found. Some copper pyrites appear among these veins accompanied, it is said, by silvery-grey copper. I found no traces of this grey copper: it is probably the metalloid diallage that has given the Cerro de Guanabacoa the reputation of riches in gold and silver which it has enjoyed for ages. In some places petroleum flows* from rents in the serpentine. Springs of water are frequent; they contain a little sulphuretted hydrogen, and deposit oxide of iron. The Baths of Bareto are agreeable, but of nearly the same temperature as the atmosphere. The geologic constitution of this group of serpentine rocks, from its insulated position, its veins, its connection with syenite and the fact of its rising up across shell-formations, merits particular attention. Feldspar with a basis of souda (compact feldspar) forms, with diallage, the euphotide and serpentine; with pyroxene, dolerite and basalt; and with garnet, eclogyte. These five rocks, dispersed over the whole globe, charged with oxidulated and titanious iron, are probably of similar origin. It is easy to distinguish two formations in the euphotide; one is destitute of amphibole, even when it alternates with amphibolic rocks (Joria in Piedmont, Regla in the island of Cuba) rich in pure serpentine, in metalloid diallage and sometimes in jasper (Tuscany, Saxony); the other, strongly charged with amphibole, often passing to diorite,* has no jasper in layers, and sometimes contains rich veins of copper; (Silesia, Mussinet in Piedmont, the Pyrenees, Parapara in Venezuela, Copper Mountains of North America). It is the latter formation of euphotide which, by its mixture with diorite, is itself linked with hyperthenite, in which real beds of serpentine are sometimes developed in Scotland and in Norway. No volcanic rocks of a more recent period have hitherto been discovered in the island of Cuba; for instance, neither trachytes, dolerites, nor basalts. I know not whether they are found in the rest of the Great Antilles, of which the geologic constitution differs essentially from that of the series of calcareous and volcanic islands which stretch from Trinidad to the Virgin Islands. Earthquakes, which are in general less fatal at Cuba than at Porto Rico and Hayti, are most felt in the eastern part, between Cape Maysi, Santiago de Cuba and La Ciudad de Puerto Principe. Perhaps towards those regions the action of the crevice extends laterally, which is believed to cross the neck of granitic land between Port-au-Prince and Cape Tiburon and on which whole mountains were overthrown in 1770.

[* Does there exist in the Bay of the Havannah any other source of petroleum than that of Guanabacoa, or must it be admitted that the betun liquido, which in 1508 was employed by Sebastian de Ocampo for the caulking of ships, is dried up? That spring, however, fixed the attention of Ocampo on the port of the Havannah, where he gave it the name of Puerto de Carenas. It is said that abundant springs of petroleum are also found in the eastern part of the island (Manantialis de betun y chapapote) between Holguin and Mayari, and on the coast of Santiago de Cuba.]

The cavernous texture of the limestone formations (soboruco) just described, the great inclination of the shelvings, the smallness of the island, the nakedness of the plains and the proximity of the mountains that form a lofty chain on the southern coast, may be considered as among the principal causes of the want of rivers and the drought which is felt, especially in the western part of Cuba. In this respect, Hayti, Jamaica, and several of the Lesser Antilles, which contain volcanic heights covered with forests, are more favoured by nature. The lands most celebrated for their fertility are the districts of Xagua, Trinidad, Matanzas and Mariel. The valley of Guines owes its reputation to artificial irrigation (sanjas de riego). Notwithstanding the want of great rivers and the unequal fertility of the soil, the island of Cuba, by its undulated surface, its continually renewed verdure, and the distribution of its vegetable forms, presents at every step the most varied and beautiful landscape. Two trees with large, tough, and glossy leaves, the Mammea and the Calophyllum calaba, five species of palm-trees (the palma real, or Oreodoxa regia, the common cocoa-tree, the Cocos crispa, the Corypha miraguama and the C. maritima), and small shrubs constantly loaded with flowers, decorate the hills and the savannahs. The Cecropia peltata marks the humid spots. It would seem as if the whole island had been originally a forest of palm, lemon, and wild orange trees. The latter, which bear a small fruit, are probably anterior to the arrival of Europeans,* who transported thither the agrumi of the gardens; they rarely exceed the height of from ten to fifteen feet. The lemon and orange trees are most frequently separate; and the new planters, in clearing the ground by fire, distinguish the quality of the soil according as it is covered with one or other of those groups of social plants; they prefer the soil of the naranjal to that which produces the small lemon. In a country where the making of sugar is not sufficiently improved to admit of the employment of any other fuel than the bagasse (dried sugar-cane) the progressive destruction of the small woods is a positive calamity. The aridity of the soil augments in proportion as it is stripped of the trees that sheltered it from the heat of the sun; for the leaves, emitting heat under a sky always serene, occasion, as the air cools, a precipitation of aqueous vapours.

[* The best informed inhabitants of the island assert that the cultivated orange-trees brought from Asia preserve the size and all the properties of their fruits when they become wild. The Brazilians affirm that the small bitter orange which bears the name of loranja do terra and is found wild, far from the habitations of man, is of American origin.

Among the few rivers worthy of attention, the Rio Guines may be noticed, the Rio Armendaris or Chorrera, of which the waters are led to the Havannah by the Sanja de Antoneli; the Rio Canto on the north of the town of Bayamo; the Rio Maximo which rises on the east of Puerto Principe; the Rio Sagua Grande near Villa Clara; the Rio de las Palmas which issues opposite Cayo Galiado; the small rivers of Jaruco and Santa Cruz between Guanabo and Matanzas, navigable at the distance of some miles from their mouths and favourable for the shipment of sugar-casks; the Rio San Antonio which, like many others, is engulfed in the caverns of limestone rocks; the Rio Guaurabo west of the port of Trinidad; and the Rio Galafre in the fertile district of Filipinas, which throws itself into the Laguna de Cortez. The most abundant springs rise on the southern coast where, from Xagua to Punta de Sabina, over a length of forty-six leagues, the soil is extremely marshy. So great is the abundance of the waters which filter by the clefts of the stratified rock that, from the effect of an hydrostatic pressure, fresh water springs far from the coast, and amidst salt water. The jurisdiction of the Havannah is not the most fertile part of the island; and the few sugar-plantations that existed in the vicinity of the capital are now converted into farms for cattle (potreros) and fields of maize and forage, of which the profits are considerable. The agriculturists of the island of Cuba distinguish two kinds of earth, often mixed together like the squares of a draught-board, black earth (negra o prieta), clayey and full of moisture, and red earth (bermeja), more silicious and containing oxide of iron. The tierra negra is generally preferred (on account of its best preserving humidity) for the cultivation of the sugarcane, and the tierra bermeja for coffee; but many sugar plantations are established on the red soil.

The climate of the Havannah is in accordance with the extreme limits of the torrid zone: it is a tropical climate, in which a more unequal distribution of heat at different parts of the year denotes the passage to the climates of the temperate zone. Calcutta (latitude 22° 34′ north), Canton (latitude 23° 8′ north), Macao (latitude 22° 12′ north), the Havannah (latitude 23° 9′ north) and Rio Janeiro (latitude 22° 54′ south) are places which, from their position at the level of the ocean near the tropics of Cancer and Capricorn, consequently at an equal distance from the equator, afford great facilities for the study of meteorology. This study can only advance by the determination of certain numerical elements which are the indispensable basis of the laws we seek to discover. The aspect of vegetation being identical near the limits of the torrid zone and at the equator, we are accustomed to confound vaguely the climates of two zones comprised between 0 and 10°, and between 15 and 23° of latitude. The region of palm-trees, bananas and arborescent gramina extends far beyond the two tropics: but it would be dangerous to apply what has been observed at the extremity of the tropical zone to what may take place in the plains near the equator. In order to rectify those errors it is important that the mean temperature of the year and months be well known, as also the thermometric oscillations in different seasons at the parallel of the Havannah; and to prove by an exact comparison with other points alike distant from the equator, for instance, with Rio Janeiro and Macao, that the lowering of temperature observed in the island of Cuba is owing to the irruption and the stream of layers of cold air, borne from the temperate zones towards the tropics of Cancer and Capricorn. The mean temperature of the Havannah, according to four years of good observations, is 25.7° (20.6° R.), only 2° centigrade above that of the regions of America nearest the equator. The proximity of the sea raises the mean temperature of the year on the coast; but in the interior of the island, when the north winds penetrate with the same force, and where the soil rises to the height of forty toises, the mean temperature attains only 23° (18.4° R.) and does not exceed that of Cairo and Lower Egypt. The difference between the mean temperature of the hottest and coldest months rises to 12° in the interior of the island; at the Havannah and on the coast, to 8°; at Cumana, to scarcely 3°. The hottest months, July and August, attain 28.8°, at the island of Cuba, perhaps 29.5° of mean temperature, as at the equator. The coldest months are December and January; their mean temperature in the interior of the island, is 17°; at the Havannah, 21°, that is, 5 to 8° below the same months at the equator, yet still 3° above the hottest month at Paris.

It will be interesting to compare the climate of the Havannah with that of Macao and Rio Janeiro; two places, one of which is near the limit of the northern torrid zone, on the eastern coast of Asia; and the other on the eastern coast of America, towards the extremity of the southern torrid zone.

The climate of the Havannah, notwithstanding the frequency of the north and north-west winds, is hotter than that of Macao and Rio Janeiro. The former partakes of the cold which, owing to the frequency of the west winds, is felt in winter along all the eastern coast of a great continent. The proximity of spaces of land covered with mountains and table-lands renders the distribution of heat in different months of the year more unequal at Macao and Canton than in an island bounded on the west and north by the hot waters of the Gulf-stream. The winters are therefore much colder at Canton and Macao than at the Havannah: yet the latitude of Macao is 1 degree more southerly than that of the Havannah; and the latter town and Canton are, within nearly a minute, on the same parallel. The thermometer at Canton has sometimes almost reached the point zero; and by the effect of reflection, ice has been found on the terraces of houses. Although this great cold never lasts more than one day, the English merchants residing at Canton like to make chimney-fires in their apartments from November to January; while at the Havannah, the artificial warmth even of a brazero is not required. Hail is frequent and the hail-stones are extremely large in the Asiatic climate of Canton and Macao, while it is scarcely seen once in fifteen years at the Havannah. In these three places the thermometer sometimes keeps up for several hours between 0 and 4° (centigrade); and yet (a circumstance which appears to be very remarkable) snow has never been seen to fall; and notwithstanding the great lowering of the temperature, the bananas and the palm-trees are as beautiful around Canton, Macao and the Havannah as in the plains nearest the equator.

In the island of Cuba the lowering of the temperature lasts only during intervals of such short duration that in general neither the banana, the sugar-cane nor other productions of the torrid zone suffer much. We know how well plants of vigorous organization resist temporary cold, and that the orange trees of Genoa survive the fall of snow and endure cold which does not more than exceed 6 or 7° below freezing-point. As the vegetation of the island of Cuba bears the character of the vegetation of the regions near the equator, we are surprised to find even in the plains a vegetable form of the temperate climates and mountains of the equatorial part of Mexico. I have often directed the attention of botanists to this extraordinary phenomenon in the geography of plants. The pine (Pinus occidentalis) is not found in the Lesser Antilles; not even in Jamaica (between 17 3/4 and 18 1/2° of latitude). It is only seen further north, in the mountains of San Domingo, and in all that part of the island of Cuba situated between 20 and 23° of latitude. It attains a height of from sixty to seventy feet; and it is remarkable that the cahoba* (mahogany) and the pine vegetate at the island of Pinos in the same plains. We also find pines in the south-eastern part of the island of Cuba, on the declivity of the Copper Mountains where the soil is barren and sandy. The interior table-land of Mexico is covered with the same species of coniferous plants; at least the specimens brought by M. Bonpland and myself from Acaguisotla, Nevado de Toluca and Cofre de Perote do not appear to differ specifically from the Pinus occidentalis of the West India Islands described by Schwartz. Now those pines which we see at sea level in the island of Cuba, in 20 and 22° of latitude, and which belong only to the southern part of that island, do not descend on the Mexican continent between the parallels of 17 1/2 and 19 1/2°, below the elevation of 500 toises. I even observed that, on the road from Perote to Xalapa in the eastern mountains opposite to the island of Cuba, the limit of the pines is 935 toises; while in the western mountains, between Chilpanzingo and Acapulco, near Quasiniquilapa, two degrees further south, it is 580 toises and perhaps on some points 450. These anomalies of stations are very rare in the torrid zone and are probably less connected with the temperature than with the nature of the soil. In the system of the migration of plants we must suppose that the Pinus occidentalis of Cuba came from Yucatan before the opening of the channel between Cape Catoche and Cape San Antonio, and not from the United States, so rich in coniferous plants; for in Florida the species of which we have here traced the botanical geography has not been discovered.

About the end of April, M. Bonpland and myself, having completed the observations we proposed to make at the northern extremity of the torrid zone, were on the point of proceeding to Vera Cruz with the squadron of Admiral Ariztizabal; but being misled by false intelligence respecting the expedition of Captain Baudin, we were induced to relinquish the project of passing through Mexico on our way to the Philippine Islands. The public journals announced that two French sloops, the Geographe and Naturaliste, had sailed for Cape Horn; that they were to proceed along the coasts of Chili and Peru, and thence to New Holland. This intelligence revived in my mind all the projects I had formed during my stay in Paris, when I solicited the Directory to hasten the departure of Captain Baudin. On leaving Spain, I had promised to rejoin the expedition wherever I could reach it. M. Bonpland and I resolved instantly to divide our herbals into three portions, to avoid exposing to the risks of a long voyage the objects we had obtained with so much difficulty on the banks of the Orinoco, the Atabapo and the Rio Negro. We sent one collection by way of England to Germany, another by way of Cadiz to France, and a third remained at the Havannah. We had reason to congratulate ourselves on this foresight: each collection contained nearly the same species, and no precautions were neglected to have the cases, if taken by English or French vessels, remitted to Sir Joseph Banks or to the professors of natural history at the Museum at Paris. It happened fortunately that the manuscripts which I at first intended to send with the collection to Cadiz were not intrusted to our much esteemed friend and fellow traveller, Fray Juan Gonzales, of the order of the Observance of St. Francis, who had followed us to the Havannah with the view of returning to Spain. He left the island of Cuba soon after us, but the vessel in which he sailed foundered on the coast of Africa, and the cargo and crew were all lost. By this event we lost some of the duplicates of our herbals, and what was more important, all the insects which M. Bonpland had with great difficulty collected during our voyage to the Orinoco and the Rio Negro. By a singular fatality, we remained two years in the Spanish colonies without receiving a single letter from Europe............
