The district of CAMANA lies along the shore of the South Sea, north of Arequipa, and is very large, but contains many deserts, extending on the east to the chain of the Andes. Its temperature is nearly the same as the former, excepting on the mountains, where it is cold. It contains many old silver mines, but these being neglected, its chief trade consists in supplying the mines of the neighbouring district with asses and other beasts of burthen. The principal town of the same name is seventy miles north-west from Arequipa, on the river Camana near its confluence with the South Sea. The next district to the north and bounding Lima, is CONDESUYOS DE AREQUIPA, extending about thirty leagues. It is chiefly inhabited by Indians who breed the cochineal insect, with which they supply the woollen manufactures of the adjacent districts. Condesuyos abounds in gold and silver mines, but they are unworked. _Ocona_ is situated in this district, and is a port on the Pacific, ninety-six miles west-north-west of Arequipa, in sixteen degrees south latitude, on the Rio Ocona, which rises in the interior, and receives a small river flowing from lake Parina Cocha. CAYLLOMA is the next jurisdiction bounding the kingdom of La Plata on the east, and Cuzco on the north; it lies entirely among the Cordilleras of the Andes, which here divides its western branch into several ramifications, approaching very near the South Sea. Caylloma is famous for containing a very high mountain of the same name, and the sources of the _Apurimac_ or Genuine Maranon, which rises in a small lake formed by the curvature of the chain of the Andes, and flows through a long valley made by two parallel ranges of the same mountains, which divide its bed from that of the Vilcamayo on the east. The source of the _Apurimac_ is in about 16° 10' or 20' south latitude. Caylloma contains, several badly worked mines of silver; but the cold is so intense, owing to the great height of the Andes, that the inhabitants who have settled in it, are obliged to have recourse to the neighbouring districts for grain, fruits, &c.; and the country abounds with wild asses and beasts of prey. _Caylloma_, the principal place, is a village on the eastern range of the Andes, at the silver mines of the great mountain of the same name. It contains an office for receiving the king's-fifths, and for selling the quicksilver necessary in the extraction of the metals. South of Arequipa, at the distance of forty leagues, lies the district of MOQUEHUA, at sixteen leagues from the Pacific. This jurisdiction extends forty leagues to the south, in a fine climate and fertile soil, adorned with large vineyards, producing great quantities of wine and brandy, which constitute its whole commerce, and with which it supplies all the provinces, as far as Potosi on the Andes by land carriage, and by sea to Lima; and the fruits of Moquehua are also numerous and good, among which are olives of excellent quality.
