Corrientes, a province of the Argentine Republic, between the Paraná and Uruguay rivers, extending from Entre Rios to Misiones territory, with an area of 40,000 sq. m. The surface is generally flat, with numerous lakes and swamps, but has undulating stretches along the Paraná and in the east, and is heavily wooded in parts. Lake Iberà, a group of lakes and swamps covering some 1800 sq. m., is surrounded with a jungle, in which the 'tacuara' bamboo (30 feet) is conspicuous; and here jaguars and alligators abound. The mean temperature (72° F.) is the highest in the republic, but the extremes (44°—98°) are not so excessive.
As in Paraguay, Guaraní is the common language, Spanish being employed only by the official and educated classes. Cattle-raising is the chief occupation; agriculture is very backward. Population, 300,000.—The capital, Corrientes, is almost hidden among orange-groves, 15 miles below the confluence of the Paraná and the Paraguay, and takes its name from seven currents formed by points of rock above the city; vessels of 9 feet draught can reach the town at all seasons. Steamers from Buenos Ayres (832 miles) touch here almost daily, and in 1887-95 railway connection was made with the south by way of Monte Caseros. Pop. 18,000.
