Considering the pos- libilities of regions still undeveloped, Peru is likely to become an important factor among the world's copper producers. Silver, together with lead, is abundant on the eastern slopes of the Andes. Before the development of copper mining this was the most important metal mined. Over 50,000 tons of pure sil- ver are said to have been taken from the Cerro de Paco region since 1630. Mercury was the first metal to be exploited in Peru. It was formerly in great demand for the treatment of silver ores, and was produced in large amounts. Peru is undoubtedly rich in both anthracite and bituminous coal, if the limited explorations made arc a just indica- tion. The oil fields of Peru are a source of considerable wealth, and their development is constantly increasing so that petroleum is Peru's most important mineral. There are four leading fields. The wells along the coast run from out in the sea many miles inland, and vary in depth from 250 to ,^,048 ft. Among non-metallic minerals, the guano deposits on the islands of the coast are of great value. Nitrates are also found in large quantities. The most important agricultural product is sugar cane. It thrives best along the river valleys and in the La Libertad and Lima districts. Cotton is also an important pro- duct, and much coffee is grown. The culti- vation of coca, from which medicinal co- caine is obtained, is an important industry in some parts of Peru. Grapes, tropical fruits, and all kinds of vegetables are raised in large quantities. Cassava is cultivated up to an altitude of 6,000 ft.; maize is grown in all parts of the country, up to 15,000 ft., and wheat is raised in the valleys of Central Peru. Raising of live stock is an important industry, the best known cattle and sheep raising districts being on the table lands. Peruvian cattle are medium-sized, and rather inferior for food and dairy purposes, but are commercially valuable for their hides. The sheep, llama, alpaca, and vicuna are bred for their wool, over 15,000,000 pounds of this product being obtained yearly. Goats are con- sidered valuable for their skins, which are of unusually fine texture, soft, and easily handled. The leading industries of Peru are agriculture and mining; but there is every reason to believe that it will one day be- come an important manufacturing country, because of its possibilities of developing im- mense water power and its abundance of raw materials. The Peruvian government gives active assistance in the matter of increasing the trade of Peru and fostering the knowl- edge of its growth in other countries. There are in Peru 2,725 miles of railroads, about 70 per cent, owned by the government and operated by the Peruvian Corporation. Roads in the interior arc1 well-developed. There arc in all 13,000 m ot improved high- ways. Much progress is being made in road construction upon which 25,000,000 soles was spent and 20,000 men employed in 1938 Peru has well established air transport serv- ice, both internally and to other countries. Telegraph, telephone, post and wireless serv- ice arc in the hands of the Marconi Com- pany under a contract running from iQ2i to 1946. There is direct cable communication between Peruvian and other ports on the west coast of South America, with good service to all parts of the world. Steamship communication is maintained with other South American countries and with the ports of the United States, Europe and Asia. The (estimated) population of Peru is 6,673,000. Lima, the capital, has a population of 450,000. Callao, the port of Lima, has a population of 80,000; Arcquipa, of 75,000; Cuzco, the ancient seat of the Inca empire, of 40,000. The state religion is Roman Cath- olic, with complete religious liberty. The churches and monasteries are state property; about $150,000 is voted annually for public worship. Education is free and compulsory from 7 years to 14. There are good higher schools; secondary vocational schools; and for higher education there are normal schools and universities. The Universidad de San Marcos, the oldest university in America (1551), is situated at Lima, and there are also universities at Arcquipa, Cuzco, and Tripiilo. In 1921 the University of Tech- nical Schools comprising advanced schools of engineering, commerce, pedagogy, and agri- culture was established. The republic of Peru, with a constitution modelled upon that of the United States, is politically divided into twenty departments and three separate provinces. History.—From ancient times there were communities in Peru. Eventually all united un- der one empire, and the Incas, in the course of some five centuries, had reached an ad- vanced stage of civilization, previous to the Spanish invasion under Pizarro in 1531. Peru was made a viceroyalty of Spain in 1544;
