The climate of Chili is probably superior to that of any other country in Spanish America, as the air is remarkably salubrious, the inhabitants being troubled with few contagious diseases, and the extremes of heat and cold are not felt in continental Chili. The spring commences in September, summer in December, autumn in March, and winter in June. From September till March, south-east or south winds prevail, during which time the sky is clear and serene, but the north and north-west winds regularly occasion rain, and chiefly occur during the remaining months.
A singular circumstance attends the difference of climate between the countries lying on the eastern and western sides of the Chilian Andes; for though the winter is the rainy season of Chili, at that time Tucuman and Cuyo enjoy their finest weather. In the northern districts of Chili rain seldom falls; whilst in the southern parts and in the isles it is frequent. The Chilian Andes being very high, and many of them entering the regions of eternal snow, the lands lying in their neighbourhood are subject to occasional frosts, and the mountains themselves are impassable from April to November, on account of the frequent and overwhelming snow storms.
The want of rain in the northern provinces is supplied by abundant dews, and fogs are common on the coasts, but they are never of long continuance. On the whole it may be stated, that the climate of this country is temperate, and favourable for bringing forward the productions of its fertile soil.
This soil yields by cultivation all the grains common to Europe, and in the most uncultivated parts, is covered with a profuse and luxuriant vegetation. The crops are usually from sixty to eighty for one; but in the rich valleys, this proportion is greatly exceeded; but the sea-coast being the least productive, the harvests there do not give more than forty or fifty to one.
The grains most commonly sown are maize, wheat, barley and rye. Hemp and flax give abundant returns, but are not so much attended to.
European fruit trees find a genial clime in Chili, and in the southern provinces are woods of apple and quince trees, of several miles in extent, from which fruit of excellent quality is gathered. Pears, cherries, peaches, of which there are fourteen sorts, some weighing sixteen ounces; oranges, lemons and citrons, melons, &c., are every where to be seen in the fields growing without culture, and each in their kind yielding delicious fruit. Vines grow wild in the forests, and those which are planted give a red wine not inferior to the produce of any European vintage.
The olive trees thrive exceedingly, some of them reaching to a great height, and being three feet in diameter.
In the northern provinces the tropical fruits and plants grow in the greatest abundance; of these the sugar cane, the cotton plant, the banana, the pine apple, the manioc, jalap, pimento, indigo, contrayerva, tobacco, sarsaparilla, guiacum, cassia, tamarinds, pepper, canello, or white cinnamon, cocoa nut and date are the most common.
Besides the plants common to the other kingdoms of America, and the luxuriancy with which all kinds of European herbs, trees, grains and fruits, grow in Chili, this country has a long catalogue of vegetables peculiar to itself.
The plains, the valleys, and the lower mountains, are covered with beautiful trees, and with an herbage so high that it conceals the sheep which graze in it, and 3000 species of non-descript plants were collected by an able naturalist, who has enumerated the properties of some of them; of these the most singular are, a large strawberry, which is cultivated for the table, and also grows wild; the madi yielding a fine oil; relbun, a species of madder; panke, which gives a good black dye; the cachan-lahuen, a balsam equal to that of Peru; and the viravira, useful in intermittent fevers. Various kinds of creeping plants, whose flowers afford the most beautiful decorations to the gardens and forests; and the puya, whose bark is used for the same purposes as cork.
