The Extreme Inconstancy Of The Weather, And The Frequent Suppression Of Cutaneous Perspiration, Give Birth To Catarrhal Affections, Which Assume The Most Various Forms.

A European, once accustomed to the violent heat, enjoys better health at Cumana, in the valley of Aragua, and in every place where the low region of the tropics is not very humid, than at Caracas, and in those mountain-climates which are vaunted as the abode of perpetual spring.

Speaking of the yellow fever of La Guayra, I mentioned the opinion generally adopted, that this disease is propagated as little from the coast of Venezuela to the capital, as from the coast of Mexico to Xalapa. This opinion is founded on the experience of the last twenty years. The contagious disorders which were severely felt in the port of La Guayra, were scarcely felt at Caracas. I am not convinced that the American typhus, rendered endemic on the coast as the port becomes more frequented, if favoured by particular dispositions of the climate, may not become common in the valley: for the mean temperature of Caracas is considerable enough to allow the thermometer, in the hottest months, to keep between twenty-two and twenty-six degrees. The situation of Xalapa, on the declivity of the Mexican mountains, promises more security, because that town is less populous, and is five times farther distant from the sea than Caracas, and two hundred and thirty toises higher: its mean temperature being three degrees cooler. In 1696, a bishop of Venezuela, Diego de Banos, dedicated a church (ermita) to Santa Rosalia of Palermo, for having delivered the capital from the scourge of the black vomit (vomito negro), which is said to have raged for the space of sixteen months. A mass celebrated every year in the cathedral, in the beginning of September, perpetuates the remembrance of this epidemic, in the same manner as processions fix, in the Spanish colonies, the date of the great earthquakes. The year 1696 was indeed very remarkable for the yellow fever, which raged with violence in all the West India Islands, where it had only begun to gain an ascendancy in 1688. But how can we give credit to an epidemical black vomit, having lasted sixteen months without interruption, and which may be said to have passed through that very cool season when the thermometer at Caracas falls to twelve or thirteen degrees? Can the typhus be of older date in the elevated valley of Caracas, than in the most frequented ports of Terra Firma. According to Ulloa, it was unknown in Terra Firma before 1729. I doubt, therefore, the epidemic of 1696 having been the yellow fever, or real typhus of America. Some of the symptoms which accompany yellow fever are common to bilious remittent fevers; and are no more characteristic than haematemeses of that severe disease now known at the Havannah and Vera Cruz by the name of vomito. But though no accurate description satisfactorily demonstrates that the typhus of America existed at Caracas as early as the end of the seventeenth century, it is unhappily too certain, that this disease carried off in that capital a great number of European soldiers in 1802. We are filled with dismay when we reflect that, in the centre of the torrid zone, a table-land four hundred and fifty toises high, but very near the sea, does not secure the inhabitants against a scourge which was believed to belong only to the low regions of the coast.

CHAPTER 1.13.

ABODE AT CARACAS. MOUNTAINS IN THE VICINITY OF THE TOWN. EXCURSION TO THE SUMMIT OF THE SILLA. INDICATIONS OF MINES.

I remained two months at Caracas, where M. Bonpland and I lived in a large house in the most elevated part of the town. From a gallery we could survey at once the summit of the Silla, the serrated ridge of the Galipano, and the charming valley of the Guayra, the rich culture of which was pleasingly contrasted with the gloomy curtain of the surrounding mountains. It was in the dry season, and to improve the pasturage, the savannahs and the turf covering the steepest rocks were set on fire. These vast conflagrations, viewed from a distance, produce the most singular effects of light. Wherever the savannahs, following the undulating slope of the rocks, have filled up the furrows hollowed out by the waters, the flame appears in a dark night like currents of lava suspended over the valley. The vivid but steady light assumes a reddish tint, when the wind, descending from the Silla, accumulates streams of vapour in the low regions. At other times (and this effect is still more curious) these luminous bands, enveloped in thick clouds, appear only at intervals where it is clear; and as the clouds ascend, their edges reflect a splendid light. These various phenomena, so common in the tropics, acquire additional interest from the form of the mountains, the direction of the slopes, and the height of the savannahs covered with alpine grasses. During the day, the wind of Petare, blowing from the east, drives the smoke towards the town, and diminishes the transparency of the air.

If we had reason to be satisfied with the situation of our house, we had still greater cause for satisfaction in the reception we met with from all classes of the inhabitants. Though I have had the advantage, which few Spaniards have shared with me, of having successively visited Caracas, the Havannah, Santa Fe de Bogota, Quito, Lima, and Mexico, and of having been connected in these six capitals of Spanish America with men of all ranks, I will not venture to decide on the various degrees of civilization, which society has attained in the several colonies. It is easier to indicate the different shades of national improvement, and the point towards which intellectual development tends, than to compare and class things which cannot all be considered under one point of view. It appeared to me, that a strong tendency to the study of science prevailed at Mexico and Santa Fe de Bogota; more taste for literature, and whatever can charm an ardent and lively imagination, at Quito and Lima; more accurate notions of the political relations of countries, and more enlarged views on the state of colonies and their mother-countries, at the Havannah and Caracas.
