The more considerable rivers which join the Parana, on the eastern side, beginning at the north, are the Añembỹ, the Parana-panè, the Guitaỹ, the Iguazu, flowing from Brazil, by which the Mamalukes formerly came to plunder the Guaranies. This river is of no inconsiderable size, and will bear tolerably large vessels. Four leagues from the bank of the Parana you meet with a cataract thirty ells high, from which the river falls headlong, with a frightful noise, and such a foam proceeds from it that the thick vapour, covering the place like a cloud, may be seen at four leagues distance. As this cataract is utterly impassable, navigators travel by land, for some time, and drag their boats along with their hands. Three leagues from the cataract the river is only one league in width. The Ybiraytỹ, the Yabebirỹ, which flows past the Guarany towns of St. Ignatius-miri, and Nuestra Senhora de Loretto, is narrow but very deep, the St. Ambrose, the Rio de los Astores and the Rio de Sta. Lucia. Through these last-mentioned rivers we have often known those cruel pirates the Payaguas come to plunder the estates of the Spaniards, and slay the inhabitants. The Corrientes, a moderate-sized river, which rises from the neighbouring lake Yberà, formerly called Lago de los Caracaras, said to be about four miles in length, but of inconsiderable and varying breadth. Many islands which it contains, are chosen at this time by Indian runaways, as places of concealment; and we learn that, in the last century, they were inhabited by the Caracara Indians who proved very formidable, and almost invincible, to the Spaniards. However, at the command of the Governour of Buenos-Ayres, a party of our Guaranies, under Juan de Garay, happily attacked and conquered them, most of the enemies being either slain or taken captive after an obstinate defence of all the islands. These are the names of the other rivers which join the Parana. The Guanguilarò, the Espinosa, the Alcaràz, the Hernand Arias, the Pardia, the Rio de los Charruas and the Pacu. But all those streams are of lesser importance. _Jam paulò major a canamus._
