The Intermediate Zone Is At The Same Height As The First Strata Of Clouds Which Surround The Surface Of The Earth; And The Climate Of This Zone, The Temperature Of Which Is So Mild, Is Essentially Misty And Variable.

Notwithstanding the elevation of the spot, the sky is generally less blue at Caracas than at Cumana.

The aqueous vapour is less perfectly dissolved; and here, as in our climates, a greater diffusion of light diminishes the intensity of the aerial colour, by introducing white into the blue of the air. This intensity, measured with the cyanometer of Saussure, was found from November to January generally 18, never above 20 degrees. On the coasts it was from 22 to 25 degrees. I remarked, in the village of Caracas, that the wind of Petare sometimes contributes singularly to give a pale tint to the celestial vault. On the 22nd of January, the blue of the sky was at noon in the zenith feebler than I ever saw it in the torrid zone.* (* At noon, thermometer in the shade 23.7 (in the sun, out of the wind, 30.4 degrees); De Luc's hygrometer, 36.2; cyanometer, at the zenith, 12, at the horizon 9 degrees. The wind ceased at three in the afternoon. Thermometer 21; hygrometer 39.3; cyanometer 16 degrees. At six o'clock, thermometer 20.2; hygrometer 39 degrees.) It corresponded only to 12 degrees of the cyanometer. The atmosphere was then remarkably transparent, without clouds, and of extraordinary dryness. The moment the wind of Petare ceased, the blue colour rose at the zenith as high as 16 degrees. I have often observed at sea, but in a smaller degree, a similar effect of the wind on the colour of the serenest sky.

We know less exactly the mean temperature of Caracas, than that of Santa Fe de Bogota and of Mexico. I believe, however, I can demonstrate, that it cannot be very distant from twenty to twenty-two degrees. I found by my own observations, during the three very cool months of November, December, and January, taking each day the maximum and minimum of the temperature, the heights were 20.2; 20.1; 20.2 degrees.

Rains are extremely frequent at Caracas in the months of April, May, and June. The storms always come from the east and south-east, from the direction of Petare and La Valle. No hail falls in the low regions of the tropics; yet it occurs at Caracas almost every four or five years. Hail has even been seen in valleys still lower; and this phenomenon, when it does happen, makes a powerful impression on the people. Falls of aerolites are less rare with us than hail in the torrid zone, notwithstanding the frequency of thunder-storms at the elevation of three hundred toises above the level of the sea.

The cool and delightful climate we have just been describing is also suited for the culture of equinoctial productions. The sugar-cane is reared with success, even at heights exceeding that of Caracas; but in the valley, owing to the dryness of the climate, and the stony soil, the cultivation of the coffee-tree is preferred: it yields indeed but little fruit, but that little is of the finest quality. When the shrub is in blossom, the plain extending beyond Chacao presents a delightful aspect. The banana-tree, which is seen in the plantations near the town, is not the great Platano harton; but the varieties camburi and dominico, which require less heat. The great plantains are brought to the market of Caracas from the haciendas of Turiamo, situated on the coast between Burburata and Porto Cabello. The finest flavoured pine-apples are those of Baruto, of Empedrado, and of the heights of Buenavista, on the road to Victoria. When a traveller for the first time visits the valley of Caracas, he is agreeably surprised to find the culinary plants of our climates, as well as the strawberry, the vine, and almost all the fruit-trees of the temperate zone, growing beside the coffee and banana-tree. The apples and peaches esteemed the best come from Macarao, or from the western extremity of the valley. There, the quince-tree, the trunk of which attains only four or five feet in height, is so common, that it has almost become wild. Preserved apples and quinces, particularly the latter,* (* "Dulce de manzana y de membrillo," are the Spanish names of these preserves.) are much used in a country where it is thought that, before drinking water, thirst should be excited by sweetmeats. In proportion as the environs of the town have been planted with coffee, and the establishment of plantations (which dates only from the year 1795) has increased the number of agricultural negroes,* the apple and quince-trees scattered in the savannahs have given place, in the valley of Caracas, to maize and pulse. (* The consumption of provisions, especially meat, is so considerable in the towns of Spanish America, that at Caracas, in 1800, there were 40,000 oxen killed every year: while in Paris, in 1793, with a population fourteen times as great, the number amounted only to 70,000.) Rice, watered by means of small trenches, was formerly more common than it now is in the plain of Chacao. I observed in this province, as in Mexico and in all the elevated lands of the torrid zone, that, where the apple-tree is most abundant, the culture of the pear-tree is attended with great difficulty. I have been assured, that near Caracas the excellent apples sold in the markets come from trees not grafted. There are no cherry-trees. The olive-trees which I saw in the court of the convent of San Felipe de Neri, were large and fine; but the luxuriance of their vegetation prevented them from bearing fruit.

If the atmospheric constitution of the valley be favourable to the different kinds of culture on which colonial industry is based, it is not equally favourable to the health of the inhabitants, or to that of foreigners settled in the capital of Venezuela.
