The silver mine of _St. Christoval de Acochala_ was formerly the most valuable in Peru, but at present is not worked owing to the want of hands. Lipes abounds in cattle, and with vicunas, alpacas and llamas, the high chain of the Andes pervading this province. AMPARAES or YAMPARAES is a district to the east of La Plata, and bounds the province of Santa Cruz de la Sierra. Its productions are chiefly grain in its warm plains, and cattle on its high lands and cold districts. ORURO, or _San Felipe de Oruro_, is a city thirty leagues north-west of La Plata, and capital of a jurisdiction or province of the same name. The greater part of this country lying on the Andes is exceedingly cold and barren, producing only herbage for the pasture of cattle and sheep, with numerous herds of Peruvian camels. It contains many gold and silver mines which were formerly very famous, but most of them have been abandoned, though the mountains of _Popo_ still yield much silver. The capital has five convents, and four churches, and is a populous place, with a revenue office for collecting the duties on the metals. PILAYA Y PASPAYA, or CINTI, is a province lying forty leagues south of La Plata and bounded on the north by Tomina and Pomabamba, on the east by the Chiriguanos Indians, and on the west and south by Porco and Chichas. Its length is about thirty leagues and its width forty, and this province is intersected in all directions, by the Cordillera, among whose breaches and valleys its inhabitants are settled. They are dispersed in different estates, and amount to 12,000. The climate in the valleys is moderately hot, and the soil very productive. The grapes of this district are made into wine and brandies, which are much esteemed in the neighbouring provinces, and the river _San Juan_ which rises in Lipes, pervades this country. The _Toropalca_ and the _Cinti_ also fertilise the valleys through which they run, and the _Supas_ and _Agchilla_ form, by their united streams, the _Paspaya_ which divides the province from Pomabamba, and runs into the Pilcomayo. The towns of Pilaya and Paspaya were destroyed by the incursions of the Indians from the east, so that the corregidor resides on an estate in the fertile valley of Cinti; but there are some abundant lead mines in the settlement of Pototaca. The province of CHAYANTAS begins fifty leagues north-west of La Plata, extending for about forty leagues. This district is famous for its silver mines, of which it contains three, with one of copper, one of tin, and two of lead; and the _Rio Grande_ which flows through it deposits auriferous particles in its bed. The cattle in this province are barely sufficient to feed the inhabitants, who are not numerous.
