It is twenty-one leagues long and twenty-six wide. The gold mines of this district are chiefly in the mountains, and can be only worked during the summer; but they are said to amount to 234, besides five lavaderos, or washing places, in the mountain of Guindo, and some other veins near Tiltil. Santiago also possesses many silver, several copper and tin, and one lead mine. The most celebrated of the first are those of _Lampa_. Jasper has been lately found in the settlement of Montenegro, of which the people make vases, jars, pitchers and other articles. Santiago is watered by the _Mapocho_, _Colina_, and _Lampa_ rivers, besides many beautiful rivulets. It also contains Lake _Pudaguel_, which is about three leagues in length. No part of Chili surpasses this district in fertility. It produces immense quantities of corn, wine, and fruits; the peaches are particularly fine, and of a very large size. The whole mass of the Andes, on its eastern borders, seems filled with metallic substances, which are washed down by the rivers, the sands of many containing gold. The capital has been already noticed by its being the metropolis of Chili. _THE PROVINCE OF RANCAGUA_ Is bounded on the north by the Maypo, which separates it from Santiago and Melipilla; east by the Andes; west by the Pacific, and south by the Cachapoal, which river divides it from Colchagua. Its length, from east to west is about forty leagues, and its breadth, from north to south, thirteen. The country is fertile and is inhabited by about 12,000 persons of all the different castes, who live in a very dispersed manner in small farms and settlements, and are not numerous. It has several gold mines, and the mountainous parts contain fine rock crystal; near its northern border are some good medicinal springs and baths, which are resorted to by the inhabitants of the metropolis. Rancagua is watered by the _Maypo_, _Codagua_, _Cochalan_ and _Cachapoal_, or _Rapel_, near the mouth of which is a small volcano, and several smaller rivers which are of great benefit to the plantations, rendering them very productive. There are also some large lakes, which as well as the rivers contain fish in abundance. The two most celebrated of these are _Acaleu_ and _Bucalemu_, the first is six miles in circuit, near the centre of the province; and the latter, near the sea, is from six to seven leagues in length; near this is a smaller one, from which much salt is obtained. Its capital is _Rancagua_, or _Santa Cruz de Triana_, a small town situated in 34° 18' south latitude, and 70° 42' west longitude, on the north shore of the river Cachapoal, and fifty-three miles south of Santiago. It has a parish church, a convent of Franciscans and another of Mercedarii. A town named _Algue_, has been recently built, eight leagues, from the capital towards the sea-coast, on account of a very rich gold mine discovered in its neighbourhood. _THE PROVINCE OF COLCHAGUA_
