PROVINCE OF PARA. 



Seventy miles lower the Hj^abary enters, which has its source in the territories 

 of the Torromonas in 1 1° 30/ 



Upwards of one hundred miles further is the mouth of the large I^a, which 

 originates in the skirts of the said cordillera to the north-east of the Napo, 

 and in the vicinity of St. Joam de Pasto, with the name of Putumajo. 



The Hyutahy and the Hyurba follow ; they are less than the preceding, being 

 about three hundred and sixty fathoms in width, and next to the TefFe, the 

 Coary, and the Purus, which are discharged by many mouths. 



On the northern margin it receives the great river Hyapura, after an extensive 

 course from the province of Popayan. This river runs parallel with the Maran- 

 ham for a considerable distance, discharging itself in that space by nine chan- 

 nels, the mouth of the first being three hundred miles to the west of the last. 

 Auatiparana, Euiratyba, Manhana, Uaranapu, Hyapura, Unana, Copeya, 

 Hyucara, and Cadaya, are the names of the channels, and the order by which 

 the Hyapura enters the Maranham. The Maranham is estimated to be nearly 

 a mile and a half in width, at a certain part, free from islands, about twenty 

 miles below the Purus, where the bottom, it is said, could not be found with a 

 cord of one hundred and three fathoms. 



After the Hyapura, its waters are swelled by the entrance, also on the northern 

 side of the Rio Negro, almost equalling it in width and volume ; and sixty 

 miles lower, on the right, by the river Madeira, nearly two miles in width, being 

 the most considerable of all the subordinate torrents that fill up the vast space 

 between the receding margins of this wonderful river. The river Madeira was 

 designated Cayary, until the Portuguese gave it the former denomination, in 

 consequence of the large trunks of trees, some of cedar, of an extraordinary 

 size, that floated down at the period of the floods, Madeira being the Portu- 

 guese word for wood or timber. It takes this name at the confluence of the 

 Guapore with the Mamore, which latter has its source in the province of Potoze, 

 traversing that of Santa Cruz, and describing a vast semicircle by the east to- 

 wards the north, being enlarged by numerous other currents, which join it on 

 both sides to the said confluence, in latitude 10° 22'. One hundred and forty 

 miles above this point, in the parallel of 13°, it communicates with the Benni, 

 by the river Exaltacao, issuing from the lake Rogagualo, from which another of 

 short extent flows to the Mamore. 



In front of the angle of the confluence of the Mamore with the Guapore, 

 there is an island of rock, well adapted for the site of a fort, which would com- 

 mand the entrance of both rivers. Upwards of nine hundred miles is com-
