The savannah we crossed to the Indian village of Santa Cruz is composed of several smooth plateaux, lying above each other like terraces. This geological phenomenon, which is repeated in every climate, seems to indicate a long abode of the waters in basins that have poured them from one to the other. The calcareous rock is no longer visible, but is covered with a thick layer of mould. The last time we saw it in the forest of Santa Maria it was slightly porous, and looked more like the limestone of Cumanacoa than that of Caripe. We there found brown iron-ore disseminated in patches, and if we were not deceived in our observation, a Cornu-ammonis, which we could not succeed in our attempt to detach. It was seven inches in diameter. This fact is the more important, as in this part of America we have never seen ammonites. The Mission of Santa Cruz is situated in the midst of the plain. We reached it towards the evening, suffering much from thirst, having travelled nearly eight hours without finding water. The thermometer kept at 26 degrees; accordingly we were not more than 190 toises above the level of the sea.
We passed the night in one of those ajupas called King's houses, which, as I have already said, serve as tambos or caravanserais to travellers. The rains prevented any observations of the stars; and the next day, the 23rd of September, we continued our descent towards the gulf of Cariaco. Beyond Santa Cruz a thick forest again appears; and in it we found, under tufts of melastomas, a beautiful fern, with osmundia leaves, which forms a new genus of the order of polypodiaceous plants.* (* Polybotya.)
Having reached the mission of Catuaro, we were desirous of continuing our journey eastward by Santa Rosalia, Casanay, San Josef, Carupano, Rio Carives, and the Montana of Paria; but we learnt with great regret, that torrents of rain had rendered the roads impassable, and that we should run the risk of losing the plants we had already gathered. A rich planter of cacao-trees was to accompany us from Santa Rosalia to the port of Carupano; but when the time of departure approached, we were informed that his affairs had called him to Cumana. We resolved in consequence to embark at Cariaco, and to return directly by the gulf, instead of passing between the island of Margareta and the isthmus of Araya. The Mission of Catuaro is situated on a very wild spot. Trees of full growth still surround the church, and the tigers come by night to devour the poultry and swine belonging to the Indians. We lodged at the dwelling of the priest, a monk of the congregation of the Observance, to whom the Capuchins had confided the Mission, because priests of their own community were wanting.
At this Mission we met Don Alexandro Mexia, the corregidor of the district, an amiable and well-educated man. He gave us three Indians, who, armed with their machetes, were to precede us, and cut our way through the forest. In this country, so little frequented, the power of vegetation is such at the period of the great rains, that a man on horseback can with difficulty make his way through narrow paths, covered with lianas and intertwining branches. To our great annoyance, the missionary of Catuaro insisted on conducting us to Cariaco; and we could not decline the proposal. The movement for independence, which had nearly broken out at Caracas in 1798, had been preceded and followed by great agitation among the slaves at Coro, Maracaybo, and Cariaco. At the last of these places an unfortunate negro had been condemned to die, and our host, the vicar of Catuaro, was going thither to offer him spiritual comfort. During our journey we could not escape conversations, in which the missionary pertinaciously insisted on the necessity of the slave-trade, on the innate wickedness of the blacks, and the benefit they derived from their state of slavery among the Christians! The mildness of Spanish legislation, compared with the Black Code of most other nations that have possessions in either of the Indies, cannot be denied. But such is the state of the negroes, that justice, far from efficaciously protecting them during their lives, cannot even punish acts of barbarity which cause their death.
The road we took across the forest of Catuaro resembled the descent of the mountain Santa Maria; here also, the most difficult and dangerous places have fanciful names. We walked as in a narrow furrow, scooped out by torrents, and filled with fine tenacious clay. The mules lowered their cruppers and slid down the steepest slopes. This descent is called Saca Manteca.* (* Or the Butter-Slope. Manteca in Spanish signifies butter.) There is no danger in the descent, owing to the great address of the mules of this country. The clay, which renders the soil so slippery, is produced by the numerous layers of sandstone and schistose clay crossing the bluish grey alpine limestone. This last disappears as we draw nearer to Cariaco. When we reached the mountain of Meapira, we found it formed in great part of a white limestone, filled with fossil remains, and from the grains of quartz agglutinated in the mass, it appeared to belong to the great formation of the sea-coast breccias. We descended this mountain on the strata of the rock, the section of which forms steps of unequal height. Farther on, going out of the forest, we reached the hill of Buenavista,* (* Mountain of the Fine Prospect.) well deserving the name it bears; since it commands a view of the town of Cariaco, situated in the midst of a vast plain filled with plantations, huts, and scattered groups of cocoa-palms. To the west of Cariaco extends the wide gulf; which a wall of rock separates from the ocean: and towards the east are seen, like bluish clouds, the high mountains of Paria and Areo. This is one of the most extensive and magnificent prospects that can be enjoyed on the coast of New Andalusia. In the town of Cariaco we found a great part of the inhabitants suffering from intermittent fever; a disease which in autumn assumes a formidable character. When we consider the extreme fertility of the surrounding plains, their moisture, and the mass of vegetation with which they are covered, we may easily conceive why, amidst so much decomposition of organic matter, the inhabitants do not enjoy that salubrity of air which characterizes the climate of Cumana.
The chain of calcareous mountains of the Brigantine and the Cocollar sends off a considerable branch to the north, which joins the primitive mountains of the coast. This branch bears the name of Sierra de Meapire; but towards the town of Cariaco it is called Cerro Grande de Curiaco. Its mean height did not appear to be more than 150 or 200 toises. It was composed, where I could examine it, of the calcareous breccias of the sea-coast. Marly and calcareous beds alternate with other beds containing grains of quartz. It is a very striking phenomenon for those who study the physical aspect of a country, to see a transverse ridge connect at right angles two parallel ridges, of which one, the more southern, is composed of secondary rocks, and the other, the more northern, of primitive rocks. The latter presents, nearly as far as the meridian of Carupano, only mica-slate; but to the east of this point, where it communicates by a transverse ridge (the Sierra de Meapire) with the limestone range, it contains lamellar gypsum, compact limestone, and other rocks of secondary formation. It might be supposed that the southern ridge has transferred these rocks to the northern chain.
When standing on the summit of the Cerro del Meapire, we see the mountain currents flow on one side to the gulf of Paria, and on the other to the gulf of Cariaco. East and west of the ridge there are low and marshy grounds, spreading out without interruption; and if it be admitted that both gulfs owe their origin to the sinking of the earth, and to rents caused by earthquakes, we must suppose that the Cerro de Meapire has resisted the convulsive movements of the globe, and hindered the waters of the gulf of Paria from uniting with those of the gulf of Cariaco. But for this rocky dyke, the isthmus itself in all probability would have had no existence; and from the castle of Araya as far as Cape Paria, the whole mass of the mountains of the coast would have formed a narrow island, parallel to the island of Santa Margareta, and four times as long. Not only do the inspection of the ground, and considerations deduced from its relievo, confirm these opinions; but a mere glance of the configuration of the coasts, and a geological map of the country, would suggest the same ideas. It would appear that the island of Margareta has been heretofore attached to the coast-chain of Araya by the peninsula of Chacopata and the Caribbee islands, Lobo and Coche, in the same manner as this chain is still connected with that of the Cocollar and Caripe by the ridge of Meapire.
At present we perceive that the humid plains which stretch east and west of the ridge, and which are improperly called the valleys San Bonifacio and Cariaco, are enlarging by gaining on the sea. The waters are receding, and these changes of the shore are very remarkable, more particularly on the coast of Cumana. If the level of the soil seem to indicate that the two gulfs of Cariaco and Paria formerly occupied a much more considerable space, we cannot doubt that at present the land is progressively extending. Near Cumana, a battery, called La Boca, was built in 1791 on the very margin of the sea; in 1799 we saw it very far inland. At the mouth of the Rio Neveri, near the Morro of Nueva Barcelona, the retreat of the waters is still more rapid. This local phenomenon is probably assignable to accumulations of sand, the progress of which has not yet been sufficiently examined. Descending the Sierra de Meapire, which forms the isthmus between the plains of San Bonifacio and Cariaco, we find towards the east the great lake of Putacuao, which communicates with the river Areo, and is four or five leagues in diameter. The mountainous lands that surround this basin are known only to the natives. There are found those great boa serpents known to the Chayma Indians by the name of guainas, and to which they fabulously attribute a sting under the tail. Descending the Sierra de Meapire to the west, we find at first a hollow ground (tierra hueca) which, during the great earthquakes of 1766, threw out asphaltum enveloped in viscous petroleum. Farther on, a numberless quantity of sulphureous thermal springs* are seen issuing from the soil (* El Llano de Aguas calientes, east-north-east of Cariaco, at the distance of two leagues.); and at length we reach the borders of the lake of Campoma, the exhalations from which contribute to the insalubrity of the climate of Cariaco. The natives believe that the hollow is formed by the engulfing of the hot springs; and, judging from the sound heard under the hoofs of the horses, we must conclude that the subterranean cavities are continued from west to east nearly as far as Casanay, a length of three or four thousand toises. A little river, the Rio Azul, runs through these plains which are rent into crevices by earthquakes. These earthquakes have a particular centre of action, and seldom extend as far as Cumana. The waters of the Rio Azul are cold and limpid; they rise on the western declivity of the mountain of Meapire, and it is believed that they are augmented by infiltrations from the lake Putacuao, situated on the other side of the chain. The little river, together with the sulphureous hot springs, fall into the Laguna de Campoma. This is a name given to a great lagoon, which is divided in dry weather into three basins situated north-west of the town of Cariaco, near the extremity of the gulf. Fetid exhalations arise continually from the stagnant water of this lagoon. The smell of sulphuretted hydrogen is mingled with that of putrid fishes and rotting plants.
Miasms are formed in the valley of Cariaco, as in the Campagna of Rome; but the hot climate of the tropics increases their deleterious energy. These miasms are probably ternary or quaternary combinations of azote, phosphorus, hydrogen, carbon, and sulphur.
The situation of the lagoon of Campoma renders the north-west wind, which blows frequently after sunset, very pernicious to the inhabitants of the little town of Cariaco. Its influence can be the less doubted, as intermitting fevers are observed to degenerate into typhoid fevers, in proportion as we approach the lagoon, which is the principal focus of putrid miasms. Whole families of free negroes, who have small plantations on the northern coast of the gulf of Cariaco, languish in their hammocks from the beginning of the rainy season. These intermittent fevers assume a dangerous character, when persons, debilitated by long labour and copious perspiration, expose themselves to the fine rains, which frequently fall as evening advances. Nevertheless, the men of colour, and particularly the Creole negroes, resist much better than any other race, the influence of the climate. Lemonade and infusions of Scoparia dulcis are given to the sick; but the cuspare, which is the cinchona of Angostura, is seldom used.
