In Many Parts Coffee And Cotton-Trees Progressively Take Place Of The Cacao, Of Which The Lingering Harvests Weary The Patience Of The Cultivator.

It is also asserted, that the new plantations of cacao are less productive than the old; the trees do not acquire the same vigour, and yield later and less abundant fruit.

The soil is still said to be exhausted; but probably it is rather the atmosphere that is changed by the progress of clearing and cultivation. The air that reposes on a virgin soil covered with forests is loaded with humidity and those gaseous mixtures that serve for the nutriment of plants, and arise from the decomposition of organic substances. When a country has been long subjected to cultivation, it is not the proportions between the azote and oxygen that vary. The constituent bases of the atmosphere remain unaltered; but it no longer contains, in a state of suspension, those binary and ternary mixtures of carbon, hydrogen, and nitrogen, which a virgin soil exhales, and which are regarded as a source of fecundity. The air, purer and less charged with miasmata and heterogeneous emanations, becomes at the same time drier. The elasticity of the vapours undergoes a sensible diminution. On land long cleared, and consequently little favourable to the cultivation of the cacao-tree (as, for instance, in the West India Islands), the fruit is almost as small as that of the wild cacao-tree. It is on the banks of the Upper Orinoco, after having crossed the Llanos, that we find the true country of the cacao-tree; thick forests, in which, on a virgin soil, and surrounded by an atmosphere continually humid, the trees furnish, from the fourth year, abundant crops. Wherever the soil is not exhausted, the fruit has become by cultivation larger and bitter, but also later.

On seeing the produce of cacao gradually diminish in Terra Firma, it may be inquired, whether the consumption will diminish in the same proportion in Spain, Italy, and the rest of Europe; or whether it be not probable, that by the destruction of the cacao plantations, the price will augment sufficiently to rouse anew the industry of the cultivator. This latter opinion is generally admitted by those who deplore, at Caracas, the diminution of so ancient and profitable a branch of commerce. In proportion as civilization extends towards the humid forests of the interior, the banks of the Orinoco and the Amazon, or towards the valleys that furrow the eastern declivity of the Andes, the new planters will find lands and an atmosphere equally favourable to the culture of the cacao-tree.

The Spaniards, in general, dislike a mixture of vanilla with the cacao, as irritating the nervous system; the fruit, therefore, of that orchideous plant is entirely neglected in the province of Caracas, though abundant crops of it might be gathered on the moist and feverish coast between Porto Cabello and Ocumare; especially at Turiamo, where the fruits of the Epidendrum vanilla attain the length of eleven or twelve inches. The English and the Anglo-Americans often seek to make purchases of vanilla at the port of La Guayra, but the merchants procure with difficulty a very small quantity. In the valleys that descend from the chain of the coast towards the Caribbean Sea, in the province of Truxillo, as well as in the Missions of Guiana, near the cataracts of the Orinoco, a great quantity of vanilla might be collected; the produce of which would be still more abundant, if, according to the practice of the Mexicans, the plant were disengaged, from time to time, from the creeping plants by which it is entwined and stifled.

The hot and fertile valleys of the Cordillera of the coast of Venezuela occupy a tract of land which, on the west, towards the lake of Maracaybo, displays a remarkable variety of scenery. I shall exhibit in one view, to close this chapter, the facts I have been able to collect respecting the quality of the soil and the metallic riches of the districts of Aroa, of Barquesimeto, and of Carora.

From the Sierra Nevada of Merida, and the paramos of Niquitao, Bocono, and Las Rosas,* (Many travellers, who were monks, have asserted that the little Paramo de Las Rosas, the height of which appears to be more than 1,600 toises, is covered with rosemary, and the red and white roses of Europe grow wild there. These roses are gathered to decorate the altars in the neighbouring villages on the festivals of the church. By what accident has our Rosa centifolia become wild in this country, while we nowhere found it in the Andes of Quito and Peru? Can it really be the rose-tree of our garden?) which contain the valuable bark-tree, the eastern Cordillera of New Granada* (* The bark exported from the port of Maracaybo does not come from the territory of Venezuela, but from the mountains of Pamplona in New Grenada, being brought down the Rio de San Faustino, that flows into the lake of Maracaybo. (Pombo, Noticias sobre las Quinas, 1814 page 65.) Some is collected near Merida, in the ravine of Viscucucuy.) decreases in height so rapidly, that, between the ninth and tenth degrees of latitude, it forms only a chain of little mountains, which, stretching to the north-east by the Altar and Torito, separates the rivers that join the Apure and the Orinoco from those numerous rivers that flow either into the Caribbean Sea or the lake of Maracaybo. On this dividing ridge are built the towns of Nirgua, San Felipe el Fuerte, Barquesimeto, and Tocuyo. The first three are in a very hot climate; but Tocuyo enjoys great coolness, and we heard with surprise, that, beneath so fine a sky, the inhabitants have a strong propensity to suicide. The ground rises towards the south; for Truxillo, the lake of Urao, from which carbonate of soda is extracted, and La Grita, all to the east of the Cordillera, though no farther distant, are four or five hundred toises high.
