Chapter 2: 16 (4)

Among the rivers which descend north-east toward the coast of Porto Cabello, and La Punta de Hicacos, the most remarkable are those of Tocuyo, Aroa, and Yaracuy. Were it not for the miasmata which infect the atmosphere, the valleys of Aroa and of Yaracuy would perhaps be more populous than those of Aragua. Navigable rivers would even give the former the advantage of facilitating the exportation of their own crops of sugar and cacao, and that of the productions of the neighbouring lands; as the wheat of Quibor, the cattle of Monai, and the copper of Aroa. The mines from which this copper is extracted, are in a lateral valley, opening into that of Aroa; and which is less hot, and less unhealthy, than the ravines nearer the sea. In the latter the Indians have their gold-washings, and the soil conceals rich copper-ores, which no one has yet attempted to extract. The ancient mines of Aroa, after having been long neglected, have been wrought anew by the care of Don Antonio Henriquez, whom we met at San Fernando on the borders of the Apure. The total produce of metallic copper is twelve or fifteen hundred quintals a year. This copper, known at Cadiz by the name of Caracas copper, is of excellent quality. It is even preferred to that of Sweden, and of Coquimbo in Chile. Part of the copper of Aroa is employed for making bells, which are cast on the spot. Some ores of silver have been recently discovered between Aroa and Nirgua, near Guanita, in the mountain of San Pablo. Grains of gold are found in all the mountainous lands between the Rio Yaracuy, the town of San Felipe, Nirgua, and Barquesimeto; particularly in the Rio de Santa Cruz, in which the Indian gold-gatherers have sometimes found lumps of the value of four or five piastres. Do the neighbouring rocks of mica-slate and gneiss contain veins? or is the gold disseminated here, as in the granites of Guadarama in Spain, and of the Fichtelberg in Franconia, throughout the whole mass of the rock? Possibly the waters, in filtering through it, bring together the disseminated grains of gold; in which case every attempt to work the rock would be useless. In the Savana de la Miel, near the town of Barquesimeto, a shaft has been sunk in a black shining slate resembling ampelite. The minerals extracted from this shaft, which were sent to me at Caracas, were quartz, non-auriferous pyrites, and carbonated lead, crystallized in needles of a silky lustre.

In the early times of the conquest the working of the mines of Nirgua and of Buria* was begun, notwithstanding the incursions of the warlike nation of the Giraharas. (* The valley of Buria, and the little river of the same name, communicate with the valley of the Rio Coxede, or the Rio de Barquesimeto.) In this very district the accumulation of negro slaves in 1553 gave rise to an event bearing some analogy to the insurrection in St. Domingo. A negro slave excited an insurrection among the miners of the Real de San Felipe de Buria. He retired into the woods, and founded, with two hundred of his companions, a town, where he was proclaimed king. Miguel, this new king, was a friend to pomp and parade. He caused his wife Guiomar, to assume the title of queen; and, according to Oviedo, he appointed ministers and counsellors of state, officers of the royal household, and even a negro bishop. He soon after ventured to attack the neighbouring town of Nueva Segovia de Barquesimeto; but, being repulsed by Diego de Losada, he perished in the conflict. This African monarchy was succeeded at Nirgua by a republic of Zamboes, the descendants of negroes and Indians. The whole municipality (cabildo) is composed of men of colour to whom the king of Spain has given the title of "his faithful and loyal subjects, the Zamboes of Nirgua." Few families of Whites will inhabit a country where the system of government is so adverse to their pretensions; and the little town is called in derision La republica de Zambos y Mulatos.

If the hot valleys of Aroa, of Yaracuy, and of the Rio Tocuyo, celebrated for their excellent timber, be rendered feverish by luxuriance of vegetation, and extreme atmospheric humidity, it is different in the savannahs of Monai and Carora. These Llanos are separated by the mountainous tract of Tocuyo and Nirgua from the great plains of La Portuguesa and Calabozo. It is very extraordinary to see barren savannahs loaded with miasmata. No marshy ground is found there, but several phenomena indicate a disengagement of hydrogen.* (* What is that luminous phenomenon known under the name of the Lantern (farol) of Maracaybo, which is perceived every night toward the seaside as well as in the inland parts, at Merida for example, where M. Palacios observed it during two years? The distance, greater than 40 leagues, at which the light is observed, has led to the supposition that it might be owing to the effects of a thunderstorm, or of electrical explosions which might daily take place in a pass in the mountains. It is asserted that, on approaching the farol, the rolling of thunder is heard. Others vaguely allege that it is an air-volcano, and that asphaltic soils, like those of Mena, cause these inflammable exhalations which are so constant in their appearance. The phenomenon is observed on a mountainous and uninhabited spot, on the borders of the Rio Catatumbo, near the junction with the Rio Sulia. The situation of the farol is such that, being nearly in the meridian of the opening (boca) of the lake of Maracaybo, navigators are guided by it as by a lighthouse.) When travellers, who are not acquainted with natural inflammable gases, are shown the Cueva del Serrito de Monai, the people of the country love to frighten them by setting fire to the gaseous combination which is constantly accumulated in the upper part of the cavern. May we attribute the insalubrity of the atmosphere to the same causes as those which operate in the plains between Tivoli and Rome, namely, disengagements of sulphuretted hydrogen?* (* Don Carlos del Pozo has discovered in this district, at the bottom of the Quebrada de Moroturo, a stratum of clayey earth, black, strongly soiling the fingers, emitting a powerful smell of sulphur, and inflaming spontaneously when slightly moistened and exposed for a long time to the rays of the tropical sun. The detonation of this muddy substance is very violent.) Possibly, also, the mountainous lands, near the llanos of Monai, may have a baneful influence on the surrounding plains. The south-easterly winds may convey to them the putrid exhalations that rise from the ravine of Villegas, and from La Sienega de Cabra, between Carora and Carache. I am desirous of collecting every circumstance having a relation to the salubrity of the air; for, in a matter so obscure, it is only by the comparison of a great number of phenomena, that we can hope to discover the truth.

The barren yet feverish savannahs, extending from Barquesimeto to the eastern shore of the lake of Maracaybo, are partly covered with cactus; but the good silvester-cochineal, known by the vague name of grana de Carora, comes from a more temperate region, between Carora and Truxillo, and particularly from the valley of the Rio Mucuju,* to the east of Merida. (* This little river descends from the Paramo de los Conejos, and flows into the Rio Albarregas.) The inhabitants altogether neglect this production, so much sought for in commerce.
