small windings. After it follows the river Chambyra, and then the Tigre, both 

 flowing from the north-west, the latter having a course of three hundred 

 miles. 



Sixty miles below the embouchure of the Tigre, is the magnificent con- 

 fluence of the Tanguragua, with the Ucayale. The Ucayale originates in the 

 latitude of 18° south-east of the large lake Chucuito, otherwise Titicaca, and 

 one hundred and twenty miles east-north -east of the city of Arica. It runs 

 to the north and north-west, under the name of Benni, to its junction with 

 the Apurimaco, in the latitude of 11°, where both their names are lost in that of 

 the Ucayale. 



The Apurimaco rises a few leagues north of the city of Arequipa, between 

 the lake Chucuito and the Pacific Ocean, from which it is only distant about fifty 

 miles ; and runs northward, describing considerable windings, and gathering 

 various other streams, amongst which the most important are the Pampas, on the 

 left, in 13° 1 0' ; the Urubamba, on the right, in 12° 1 5' ; and the Montaro in 1 2° 6\ 

 where it changes the direction towards the north-east. Previously to mingling 

 its waters with the Benni it receives on the left the Perene, and on the right^ 

 ten miles above its mouth, the Paucartamba. 



The Montaro issues from the lake Chinchayocha, in the district of Huanaco, 

 in 11°, and flows for a considerable space to the south-east along the Cordil- 

 lera, describing extensive windings to its embouchure. 



The largest tributary of the Ucayale, after it takes this name, is the Pachitea, 

 which joins it on the left, in the latitude of 8° 30', being more handsome in its 

 appearance than considerable^ its course not exceeding two hundred miles. 



The Maranham, at the confluence where it takes this name, directs its course 

 to the north-east for one hundred miles, receiving, on the left, the Napo, which 

 originates in divers parts of the interior cordillera of the Andes, in the vicinity 

 of Quito, from whence it flows to the south-east, collecting various others, and, 

 after a course of five hundred and fifty miles, discharges itself by diflferent 

 channels, formed by several islands, above which it is twelve hundred yards in 

 width. 



With this river the Maranham becomes eighteen hundred yards wide, yet 

 having acquired only a small portion of the volume of water with which it enters 

 the ocean, from whence it is here distant thirteen hundred miles in a direct line. 

 At this part it inclines to the east, and, after fifty miles of course, receives by the 

 right the Cassiquin, which comes from the south, with three hundred and fifty 

 miles of extent.
