San Miguel is the see of a bishop who resides at Cordova. The bishopric is that of Tucuman, and was erected in 1570. In the jurisdiction which surrounds it, is found a tree, named Quebracho, on account of its great hardness, which often breaks the axe, and becoming, when steeped in water, as solid as stone. The salt river, Sali is about a league south of this city.

Cordoba, or Cordova de la Nueva Andalucia, is in 31° 30' south latitude, 63° 15' west longitude, 156 leagues from Buenos Ayres, at the foot of the Andes, and was founded, in 1550, by Juan Nuñez de Prado. The river Primero, so called because it is the first of five, is in its vicinity, and a hill of some height adjoins it, so that, although in the plain, the water easily passes off.

This city approaches a square form, with many good houses, a large but irregular cathedral, three convents, and two colleges. Few places of the same extent display equal wealth, the Spaniards and Creoles being noted for their industry. The chief trade is to the fair at Salta, in mules, where they are sold for Peru, and the town of Cordova contains many slaves, who weave and make their own cloths.

The bishop and chapter also reside here.

Wine and grain are brought from Mendoza in Cuyo, brandy in leathern bags from St. Juan de la Frontera, and meat and fruits are abundantly supplied in the neighbourhood. Cordova is the capital of a province or district of the same name, extending about 100 leagues in length, and seventy in breadth, intersected by a chain of mountains, and celebrated for its woollen manufactures.

The mountains which traverse this province are covered with perpetual snow, and at Ramauso, sixty miles from Cordova, they branch out, and are so far from each other that a saline plain, seventy miles in length, extends to Tucuman, in which nothing grows but the salsola kali, nearly four yards in height, amid the white incrustations of fossil salt.

The decayed city of St. Jago del Estero is in this plain, 650 miles north-north-west of Buenos Ayres, in 27° 46' south latitude, and 65° 12' west longitude, on the banks of the Dolce, which is large and navigable, and affords great variety of fish. It contains about 300 houses, or 500 families, of mulattoes and mestizoes, of a dark yellow complexion and sickly appearance, from the great heat of the climate; as surrounded on one side with the plain, and on the other with deep forests; the place suffers from a stagnation of the air. The women are subject to goitrous swellings, which much disfigure them, though they are generally handsome when not afflicted with this disease; and the country near the woods produces wheat, rice, barley, and all sorts of fruits, particularly figs and raisins; the forests supplying game, but are infested with jaguars and beasts of prey.

Rioxa, or Todos Santos de Rioja, is a small city, founded, in 1591, by Juan Ramirez de Velasco, on a plain of great extent, bounded on the west by the mountains, in which the inhabitants breed some cattle.

Its territory produces cotton, grain and vines, but the soil is poor.

This city contains a parish church, three convents and an ancient college of the Jesuits, being in 29° 12' south latitude, and 70° west longitude, 240 miles west-south-west of St. Jago del Estero.
