that of the Jacuhy-Mirim. These rivers were so named after cattle began to 

 graze near them. The gentle course of the Jacuhy is uninterrupted by cataracts, 

 and is perfectly free to navigation. The Irapuan receives a great many 

 currents, almost all muddy and brackish, and very cold. A species of soft 

 black stone, with white particles like silver, are found upon many parts of its 

 banks. On being burnt, it emits a sulphureous smell, assumes the appearance 

 of charcoal, and is said to be of no higher value. The Butucarai comes from the 

 north, and has a bridge. Near its mouth is the passage of Fandango. The 

 Pigueri joins the Irohy, and comes from the Serro Pellado da Encruzilhada. 

 The Tubatingahy originates between a serro and the Encruzilhada. The Pardo, 

 having its source in a serra, runs through a country covered with wild woods ; 

 the large stones in its bed preclude navigation : it is passed by a bridge. The 

 Capibari flows from the vicinity of the source of the Irohy. The Antos, 

 formed by various currents, which issue from the lower part of the cordillera, 

 after a considerable course towards the west, turns to the south, receives the 

 Tibicoari, and, ten leagues farther, under the latter name, enters the Jacuhy, 

 of which it is the largest tributary, affording an open navigation to yachts as 

 far as the confluence, where it loses the first name. The adjacent country 

 is fertile, producing beautiful pine and other trees of excellent timber. The 

 Jacuhy, (ten leagues below the Jacoari,) at the part where on a sudden it turns^ 

 to the south, is two miles in width, forming a bay, where it receives the Cahy, 

 which issues from the plains on the summit of the General Serra, with a course 

 of about twenty-five leagues, almost south, and affording a navigation to yachts 

 of ten leagues. The Sino, something smaller, which rises on the top of the 

 same serra, more to the south, runs south-west, and is navigable for a con- 

 siderable distance. The Gravatahy, which has its origin in the same hills, 

 further to the south, runs in the same direction, and affords navigation for a 

 space of five leagues. 



The rivers Igarupay, Daymar, and Gualeguay, are the principal ones which 

 enter the Uruguay, by the left bank, between the mouths of the Ibicui and the 

 Negro. 



The Maldonado, and the two rivers SoHs, (small and great,) discharge 

 themselves into the gulf of the river Plate. Rio Grande de St. Pedro is the 

 name of the outlet of the lake of Patos, and is about ten miles in length almost 

 north and south, near one league in width, and is situated sixty leagues north- 

 east from Cape St. Mary. The lateral lands are very flat, and destitute of 

 trees or building's to direct the navigator, who, at a distance only of two
