, ULLOa's voyage to south AMERICA. 499 



Eaftward of Ucayale, the Maranon receives the river Yabari, and afterv/ards 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 v^'hich the latter palTes being inhabited by wild Indians, and confe- 

 quently 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 cer- 

 tain months of the year it is navigable. There is indeed a tradition of voyages made 

 upon 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 1 7* and 1 8"^ of fouth latitude. From this 

 river downwards, the Maranon 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 further joined by the rivers 

 Zingu, Dos Bocas, Tocantines, and Muju, all iffuing 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 proceed to thofe, 

 the fources of which are nearer, iffuing from the Cordilleras, and which immediately 

 run into the eaftern diredion ; and alfo thofe which join it from the north. 



In the mountains and Cordilleras of Loja and Zamora rife feveral little rivers, the 

 conflux of which forms that of Santiago ; and from thefe of Cuenca, others which 

 unite in the Paute : but this, on its union with the former, lofes its name, being ab- 

 forbed by the Santiago, Tfo called from a city of that name) near which it joins the two 

 others from Lauricocha and Apurimac. The river Morona iffues from the lofty deferts 

 of Sangay ; and pafling very near the city of Macas, runs in a fouth-eaft courfe, till it 

 lofes itfelf in the principal channel of the Maranon ; which happens at the diftance of 

 about twenty leagues eaft of Borja, the capital of the government of Maynas. 



In the mountains of the jurifdiftion of Riobamba, thofe of Latacunga, and the town 

 of San Miguel de Ibarra, are the fources of the rivers Paftaza and Tigre ; and from 

 Cotopaxi and Its Cordillera iffue the firft branches of the rivers Coca and Napo. Thefe, 

 though their fources are at no remarkable diftance, run to a great extent before they 

 join ; and retaining the name of Napo, fall into the Maranon, after a courfe of above 

 two hundred leagues in a dired line from eaft to weft, with fome, though infenfible, in- 

 clinations to the fouth. This is the river which father Chriftopher de Acuna, who will 

 be mentioned hereafter, takes for the true Maranon, to which, as exceeding all the reft 

 in largenefs, the others may be faid to add their waters. 



From the mountains of the jurifdiftion of San Miguel de Ibarra, and thofe of Pafto, 

 iffues the river Putu-mayo, called alfo lea, which, after running fouth-eaft and eaft 

 about three hundred leagues, joins the Maranon much more eaftward than the river 

 Napo : laftly, in the jurifdidion of Popayan, the river Caqueta has its origin, which 

 becomes divided into two branches ; the weftern, called Yupura, difembogues itfelf 

 into the Maranon like another Nile, through feven or eight mouths, and thefe are at 

 fuch a diftance, that the intermediate fpace betwixt the firft and the laft is not 

 lefs than one hundred leagues ; and the other, which runs to the eaftward, is not 

 lefs famous under the name of Negro. M. de la Condamine, in the narrative of his 

 voyage, confirms the opinion of its being one of the communications betwixt the
