=Cochabamba=, south of El Beni, east of La Paz and west of Santa Cruz, is sometimes called the granary of the Republic. It is a particularly delightful region, half temperate and half semitropical, with altitude ranging from 973 to 16,777 feet. It possesses immense plains with innumerable herds of cattle, magnificent fertile valleys, rich forests, and minerals. Cochabamba, the capital, is the city next in size to La Paz, 276 miles distant; with an altitude of 8387 feet it enjoys a delightful climate, an average temperature of 66°, and abundant rain. It has a good club, an American Institute (a school for boys), and the least illiteracy. The recent arrival of the railroad insures its rapid growth. =Potosí= is another plateau Department, both east and south of Oruro, bordering also on Chuquisaca and Tarija, and with Argentina south and Chile west. It has for the most part a rather cold, disagreeable climate, the altitude ranging from above 20,000 to a little over 6000 feet. The name Potosí, for centuries famous as almost a synonym for silver, belongs also to the capital city, at a height of 13,388 feet. In 1650, when New York was a small village, it had 160,000 inhabitants. The city has an excellent mint, built in 1562, also a superb old cathedral, a good library, and a museum. Above the town 32 artificial lakes were constructed of which 22 are still good. The temperature varies from 9° to 59°; it is said that they have the four seasons in one day. Even here potatoes, barley, and beans will grow, but living is very dear. The town has foundries, engineering shops, and 28 smelters. The Department still contains enormous quantities of silver and tin in almost every variety of combination, and more towns that are rich mining centres than any other Department except La Paz. Uyuni is a town of 6000 inhabitants, Colquechaca has a population of 8000 miners; Tupiza, soon to be reached by the railway, is a pretty city in a pleasant valley, 66 miles from the Argentine border. =Chuquisaca=, east of Potosí and south of Cochabamba and Santa Cruz, is much warmer, the altitude ranging from 255 to 13,450 feet. Here also are mines of the usual varieties and petroleum too, tropical fruits and vegetables of course, and plains with vast herds and flocks. Sucre, the legal capital of the Republic, altitude 9328 feet, is situated on an arm of the Pilcomayo River. Social distinctions are here more marked, and there is an exclusive circle agreeable to those of the right type. Sucre, Cochabamba, and La Paz are called the most cultured cities. More than 300 miles from La Paz in a straight line and, as it is on the east side of the Cordillera, much farther on horseback, which until lately was the only way to journey thither, except for some miles of staging, Sucre is now more accessible, as will be indicated later.
