The rivers of lesser note, and more uncertain duration, which unite with the Parana, after its junction with the Paraguay, are the rivers Negro, Verde, Blanco, Rubeo, the Rio de Gomez, the Atopehenra-lauatè, or the place of Capibaris, the Alcaray, the Cayman, the Embalzado, the Rio del Rey, called by the Abipones Ychimaye, the Malabrigo, called by the Abipones Neboquelatèl, the Eleya, the Saladillo, the Inespin, called by the Abipones, Narahaguem, the Rio de Martin, the Salado, the Carcaranal, the Tortugas, or river of tortoises, the Matanza, the Rio de los Arrecifes, the Areco, the Lujan, the Rio de las Conchas. We have now reached the port where vessels, coming from the east or west of Paraguay, are in danger; for here the Parana, swelled by the accession of so many rivers, and by that of the vast Uruguay, and the equally vast Rio Negro, takes the appearance of a sea. But just as the Parana does really show itself akin to the sea, it suddenly receives the name of La Plata. What is the reason of this? Has it any silver in its bosom or on its shores? Nothing is to be found there but mud. However, as Scipio received the title of Africanus, from having devastated Africa, by the same right may the Parana be called La Plata from the Peruvian silver which it has often swallowed up, along with the ships that contained it. Here the river is ten leagues wide, yet, not content with its own magnitude, it joins with itself the other ignobler streams which flow towards the west. The most noted of them is that by the Spaniards called Riachuelo.
