Parana, (1) a river of South America, rises as the Rio Grande in the Brazilian state of Minas Geraes, and is known as Parana after its junction with the Paranahyba (not the Parnahyba, q.v.). Thence its course is S., SW., and W., separating Parana state from Matto Grosso and from Paraguay, round the southern border of which republic it sweeps westward to its confluence with the Paraguay River. It then rolls southward through the Argentine provinces, past Santa Fe, below which its channel frequently divides and encloses numerous islands, and finally southeastward, till it unites with the Uruguay, above Buenos Ayres, to form the Rio de la Plata. The entire length is over 2000 miles; it drains 1,100,000 sq. m. At San Pedro (33° 40' S. lat.) a delta begins. The principal towns on its banks are Corrientes, Parana, Santa Fe, and Rosario - all Argentinian. The river is navigable to the influx of the Paraguay (705 miles), and except at low water to the mouth of the Iguassu (460 miles). Immediately above this point occurs one of the most remarkable rapids in the world, extending for 100 miles between ranges of frowning cliffs. - (2) A southern state of Brazil, on the coast, with an area of 85,453 sq. m., and a pop. of 250,000, including several colonies of Germans and Italians. The capital is Curitiba (14,000), with a railway (69 miles) to the port of Parana-gua. - (3) Capital of the Argentinian province of Entre Rios, stands on a high bluff overlooking the Parana, opposite Santa Fe, 410 miles by steamer from Buenos Ayres; pop. 25,000.
