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.
