Antofagasta comes next, separated from Tarapacá by the River Loa. On the east it has both Bolivia and a piece of northern Argentina. The surface descends from the Andes in a series of plateaus. Vegetation is scanty. This Province, with Atacama on the south, shares in the activities of the nitrate industry.

The capital city, Antofagasta, is 200 miles south of Iquique, both ports having very poor harbors, though with enormous commerce for places of their size. Antofagasta, the terminus of a third railway from La Paz, the second in Chile, has much Bolivian trade besides export of nitrates, and lately from Chuquicamata of copper. The Province contains other ports and cities of consequence, Taltal, Tocopilla, Mejillones, etc.

Atacama on the south borders exclusively at the east on Argentina, which from here down forms the eastern boundary of Chile. The surface of the Province is uneven, with mountains, plateaus, and ravines; in the valleys of Huasco and Copiapó there is some agriculture. Minerals, as gold, silver, and copper receive attention.

Copiapó, the capital, is an important railway junction.

Coquimbo, following, is a narrower Province, the mountains and the Argentine boundary coming nearer the shore. There are many lofty peaks at the east; and between spurs running down to the coast are fertile, well watered valleys, as we now come to the central section where with a mild climate there is moderate rainfall. Cereals, fruit, wine, and livestock are exported.

La Serena, the capital, is a pretty town, which has tramway connection with Coquimbo, a first class port, and a busy city.

Aconcagua is next, with the great peak of that name in the range at the east. Some 15 miles south of the peak is the Uspallata Pass, for many years the main commercial highway between Chile and Argentina. By this Pass came Almagro, and later a division of the army of San Martín; another division by the pass of Los Patos, a little lower and farther north, by which cattle are often driven into Chile. The Province is chiefly agricultural and pastoral, with crops of cereals, fruits, hemp, and tobacco. The finest wine is produced; there are large herds of cattle; and copper has some exploitation.

Valparaiso, one of the two Provinces bordering on Aconcagua at the south, is next to the smallest in the Republic, and the first coming from the north which does not extend across the country. With Aconcagua on the north it has Santiago on the east and south. The surface is mountainous with extensive valleys, the Coast Range here reaching a height of 7000 feet. Several rivers and a number of bays are among its favorable features. With a mild climate and sufficient rain agriculture is the principal industry aside from the commercial interests of the chief port of the West Coast, Valparaiso.

Santiago, south of Aconcagua and east of Valparaiso, extends from Argentina on the east, south of Valparaiso to the sea, and has the two Provinces of O’Higgins and Colchagua on the south. The Central Valley, which occupies a great part of its area, is here a broad plain, part of which is well watered and fertile but with some sections arid; the foothills and valleys are well wooded. The Central Valley slopes towards the west, having an altitude of nearly 3000 feet at the foot of the Andes, and about 1000 feet near the hills of the Coast Range. The highest point of the Andes, here south of Mt. Aconcagua, is less than 20,000 feet while the Coast Range approaches 8000. Cereals, vegetables, fruit, and wine are the chief products. Among other towns in the Province is the port of San Antonio.

O’Higgins, a very small Province, occupies what may be called a jog at the southeast corner of Santiago, which is therefore on the west and north, while Argentina is east and Colchagua south. Although a rugged district, irrigation is developed and large crops of cereals and fruit are grown. Rich in mineral deposits, copper alone is exploited.
