his expedition for the discovery oftlie Maranori, and 

 the conquest of theiidjacent countries. 



Eastward of Ucavale, the Maranon receives 

 the river Yabari, and afterwards four others, nameiy, 

 the Yutay, Yurua, Tefe, and Coari ; all running from 

 the south, where they have their source nearly in 

 the same Cordilleras as that of the Ucayale ; but the 

 countries through which the latter passes bein;:^ inha- 

 bited by wild Indians, and consequently but little 

 known to the Spaniards, its course, till its junction 

 with the Maranon, cannot be ascertained : and it is 

 only from vague accounts of some Indians, that in 

 certain months of the year it is navigable. There is 

 indeed a tra^ütion of voyages made up it, and by 

 which it was perceived to run very near the provinces 

 of Peru. 



Beyond the Rio Coari eastward, the Cucliibara, 

 also called the Purus, joins the Maranon; and after 

 that likewise the Madera, one of the largest rivers 

 that unite their waters with it. In 1741, the Portu- 

 guese sailed up it, till they found themselves not far 

 from Santa Cruz de la Sierra, betwixt 17 and 18 deg. 

 of south lat. From this river downwards, the Mara- 

 non is known among the Portuguese by the name of 

 the river of the Amazons: upwards thev í^ivcit the 

 name of the river of Soiimoes. Within a small di- 

 stance foUow's -the river of Topayos, likewise very 

 considerable ; and which has its source among the 

 mines of Brazil. After these it is further joined by 

 the rivers Zingu, dos Bocas, Tocantines, and Mtiju, 

 all issuing from the mines and mountains of Brazd ; 

 and on the eastern shore of the latter stands the city 

 of Gran P¿ira. 



Having thus given an account of the most distant 

 branches of the stately river of Maranon, and of the 

 principal ones which Join it from the south, I pro- 

 ceed to those, the sources of which are nearer, issuing: 

 from the Cordilleras, and which immediately run in^
