The Chain Of Mountains
Which Separates The Port From The High Valley Of Caracas, Descends
Almost Directly Into The Sea; And The Houses Of The Town Are Backed
By A Wall Of Steep Rocks.
There scarcely remains one hundred or one
hundred and forty toises breadth of flat ground between the wall
and the ocean.
The town has six or eight thousand inhabitants, and
contains only two streets, running parallel with each other east
and west. It is commanded by the battery of Cerro Colorado; and its
fortifications along the sea-shore are well disposed, and kept in
repair. The aspect of this place has in it something solitary and
gloomy; we seemed not to be on a continent, covered with vast
forests, but on a rocky island, destitute of vegetation. With the
exception of Cabo Blanco and the cocoa-trees of Maiquetia, no view
meets the eye but that of the horizon, the sea, and the azure vault
of heaven. The heat is excessive during the day, and most
frequently during the night. The climate of La Guayra is justly
considered to be hotter than that of Cumana, Porto Cabello, and
Coro, because the sea-breeze is less felt, and the air is heated by
the radiant caloric which the perpendicular rocks emit from the
time the sun sets. The examination of the thermometric observations
made during nine months at La Guayra by an eminent physician,
enabled me to compare the climate of this port, with those of
Cumana, of the Havannah, and of Vera Cruz. This comparison is the
more interesting, as it furnishes an inexhaustible subject of
conversation in the Spanish colonies, and among the mariners who
frequent those latitudes. As nothing is more deceiving in such
matters than the testimony of the senses, we can judge of the
difference of climates only by numerical calculations.
The four places of which we have been speaking are considered as
the hottest on the shores of the New World. A comparison of them
may serve to confirm what we have several times observed, that it
is generally the duration of a high temperature, and not the excess
of heat, or its absolute quantity, which occasions the sufferings
of the inhabitants of the torrid zone.
A series of thermometric observations shows, that La Guayra is one
of the hottest places on the earth; that the quantity of heat which
it receives in the course of a year is a little greater than that
felt at Cumana; but that in the months of November, December, and
January (at equal distance from the two passages of the sun through
the zenith of the town), the atmosphere cools more at La Guayra.
May not this cooling, much slighter than that which is felt almost
at the same time at Vera Cruz and at the Havannah, be the effect of
the more westerly position of La Guayra? The aerial ocean, which
appears to form only one mass, is agitated by currents, the limits
of which are fixed by immutable laws; and its temperature is
variously modified by the configuration of the lands and seas by
which it is sustained.
