Is bounded on the north by Quillota, east by the Andes, west by Quillota, and south by Santiago. It is about the same extent as Quillota, and is a level and well watered district, producing a great quantity of grain and fruits. In the mountains which bound, and may be said to belong to it, are the famous silver mines of _Uspallata_, with several of copper. Its chief rivers are the _Longotoma_, the _Ligua_, the _Chilé_, and the _Aconcagua_; the latter of which is a very fine stream which waters, in its progress to the sea, from the Andes, the great valleys of the province and those of Curimon, Quillota, and Concon, forming numerous branches as it passes them. It enters the ocean in 33° south latitude. In this district is the high road leading to St. Juan de la Frontera, in Cuyo, by which the treasure and commodities are carried to Buenos Ayres. It is traversed, by the people employed in this traffic, only from November to April and May, the tambos and the other houses which have been erected by the government, are stored with meal, biscuit, hung beef, and fuel, during the winter, for the couriers who are obliged to go once a month for the mails from Europe, and who are frequently detained by heavy falls of snow. The inhabitants of the partido of Aconcagua amount to about 8000. Its capital is _San Felipe_, on the river Aconcagua in 32° 48' south latitude, which contains several convents, a college built by the Jesuits, and a parochial church. South-west of this city, and on the central ridge of the Andes, is the volcano of Aconcagua. The village of Curimon, near the Andes, is noted for having a convent of Franciscans who are extremely strict in their rules. _THE PROVINCE OF MELIPILLA_ Is bounded on the north by Quillota, east by Santiago, south by the river Maypo, which divides it from Rancagua, and on the west by the Pacific. Its sea coast is of little extent, and its breadth, from east to west, is about twenty-five leagues; its principal produce being wine and grain. The chief rivers are the _Maypo_, the _Maypocha_, and the _Poanque_. The chief town is _Melipilla_, or _St. Josef de Logrono_, in 33° 28' south latitude, and 70° 7' west longitude, not far from the Rio Maypo, in a beautiful situation and fertile territory, but thinly inhabited, owing to its vicinity to the metropolis. It contains a parish church, two convents, and a college founded by the Jesuits. _St. Francisco de Monte_, in which is a convent of Franciscans, and the port of _St. Antonio_, at the mouth of the Maypo, both of which are inconsiderable places, are the only other towns of any note in this province. _THE PROVINCE OF SANTIAGO_ Is bounded by Aconcagua on the north, the Andes on the east, Melipilla on the west, and the Rio Maypo on the south.
