=Santa Fé=, capital of that Province, though far smaller and less commercial than Rosario, was founded before Buenos Aires by Juan de Garay, seven miles up the small stream Quiloaza, at a time when a quieter port for their small vessels seemed more desirable than the great river, which at Rosario is 20 miles wide. An important railway centre, its port is Colastiné, opposite to Paraná, and accessible to ocean steamers. =Corrientes=, population 30,000, is a rather old fashioned quiet town in a sheep raising district, with some cattle; the last port on its left bank before the turn of the river, which beyond is called the Alto Paraná. Sailing straight north one is on the Paraguay, up which the larger steamers go to Asunción. The upper Paraná though broad is much shallower, accordingly at Corrientes smaller steamers are taken for Posadas 36 hours distant. The Aripe Rapids, 145 miles up, also make these necessary. Above Posadas, boats of still lighter draft are used for the three days’ sail to the Iguassú, where a landing for the Falls is made at Puerto Aiguirre, a mile up the river. The boats continue up the Paraná beyond the northern extremity of Argentina to the Falls of La Guayra. Continuing north from Corrientes up the Paraguay, the mouth of the Bermejo is soon passed and at Asunción the mouth of the Pilcomayo is reached, the northern boundary of this part of Argentina, the Territory of Formosa. The lower large tributary, the Bermejo, separating Formosa from the Chaco, has recently been made navigable by clearing the banks and cleaning the river bed, so that with one transshipment traffic may be carried on for 450 miles. The journey requires three weeks; but Villa Embarcación, an important centre of trade on the border of Bolivia was thus made accessible by water, the town already having rail connection with Jujuy and Salta, and being but 15 miles from Orán, another important terminus. Tropical products, as sugar, cotton, and fruit, are of value, and oil from Bolivia. The native population of El Chaco is estimated at 25,000 Indians of various tribes; as many more in Formosa. The forest covered plains are not thoroughly explored, some persons having lost their lives in the attempt; several are known to have been murdered in 1900 and 1902. Aside from these rivers there is little steamboat service in the interior.
