his expedition for the difcovery of the Maranon, and 

 the conqueft of the adjacent countries. 



Eastward of Ucayale, the Maranon receives the 

 river Yabari, and afterwards four others, namely, the 

 Yutay, Yurua, Tefe, and Coari all running from 

 the fouth, where they have their fource nearly in 

 the fame Cordilleras as that of the Ucayale , but the 

 countries through which the latter pafles being inha- 

 bited by wild Indians, and confequently but little 

 known to the Spaniards, its courfe, till its jundion 

 with the Maranon, cannot be afcertained : and it is 

 only from vague accounts of fome Indians, that in 

 certain months of the year it is navigable. There is 

 indeed a tradition of voyages made up it, and by 

 which it was perceived to run very near the provinces 

 of Peru. 



Beyond the Rio Coari eaftward, the Cuchibara^ alfo 

 called the Purus, joins the Maranon \ and after that 

 likewife the Madera, one of the largeft rivers that 

 unite their waters with it. In 1741, the Portuguefe 

 failed up it, till they found themfelves not far from 

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

 fouth lat. From this river downwards, the Mara- 

 non is known among the Portuguefe by the name of 

 the river of the Amazons : upwards they give it the 

 name of the river of Solimoes. Within a fmall 

 diftance follows the river of Topayos, likewife very 

 confiderable ; and which has its fource among the 

 mines of Brazil. After thefe it is farther joined by 

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

 all ifluing from the mines and mountains of Brazil ; 

 and on the eaftern fhore of the latter ftands the city of 

 Gran Para. 



Having thus given an account of the moft diftant 

 branches of the ftately river of Maranon, and of the 

 principal ones which join it from the fouth, I pro- 

 ceed to thofe, the fources of which are nearer, ifliiing 

 from the Cordilleras, and which immediately run in- 

 to
