=Santa Fé=, the last of the Provinces west of the Paraná River, extends along its right bank from the Chaco on the north a distance of nearly 500 miles to the Province of Buenos Aires on the south, with Corrientes and Entre Rios on the other side of the river, and Córdoba and Santiago on the west. This State, second in population to Buenos Aires, though fifth in area, is a great plain with slight elevations, having dense forests at the north, at the south the fertile prairie, and along the great river many islands, covered with luxuriant vegetation. It is an agricultural, cattle raising country, with mills and factories also; and with extensive commerce in cereals, meat, hides, quebracho extract, and timber, from the many fluvial ports. The chief of these, Rosario, is the second largest city of the Republic with a population of 317,000. The Province contains 3000 miles of railway. =Corrientes=, east and south of the Paraná River, therefore south of Paraguay, has Misiones at the northeast, Brazil east, across the Uruguay River, Entre Rios south, and Santa Fé and the Gran Chaco west across the Paraná. The Province has temperate uplands and warmer lowlands, and is well watered by rivers and some lakes and marshes. Corrientes is prominent as a cattle-raising State and has also large flocks of sheep. The capital, Corrientes, is an important river-port visited during most of the year by vessels drawing 12 or 13 feet. Goya, farther south, is famed for its excellent cheese. =Entre Rios=, south of Corrientes, has Uruguay east beyond the Uruguay River, Buenos Aires south across the Paraná, and Santa Fé beyond the same river on the west. It is in general a fertile, well-watered plain, with a forest region at the northwest running over into Corrientes, containing much valuable timber. It is a stock-raising and an agricultural region, largely devoted to cereals, with grain of the finest quality. It has also many industrial establishments. Paraná, the capital, is a growing centre with some fine buildings, electric lights, and other facilities. Concordia, on the Uruguay River, is an important commercial town.
