the name of Apo-paru, or Gran-Paro; and continuing its impetuous course in the same direction as heretofore, in 8 degrees 26 minutes it is augmented by the waters of the Pachitea,[1] and receives the name of Ucayali. Taking a declination, in its progress, from the N. to the N. E., at the western bank, at which it receives the Pachitea, the following rivers pay it tribute: the Aguaitia, in 7 degrees 55 minutes; the Manoa, or Cuxhiabatay, in 7 degrees; the Sarayacu, in 6 degrees 45 minutes; and the Tapichi y Cano Pocati, which communicates with the Maranon in front of the town of San Regis, in 5 degrees. A bay which occupies an extent of territory of three leagues, having been formed, it divides into three branches; and finally falls in with the Maranon in 4 degrees 45 minutes, causing it to change its impetuous course, as a token of its own superiority.
Near to this celebrated confluence is situated the town of Omaguas, from which, to that of the lake, the navigation by the Maranon and Huallaga may be computed at about 70 leagues. Throughout the whole extent of this inland navigation, there do not exist any other towns, bordering on the above rivers, beside those of Urarinas and San Regis. Father Girbal having made the necessary arrangements for his peregrination, embarked on the 30th of August, four days after the return of father Sobreviela, on the lake of Gran Cocama, and reached Omaguas on the 6th of September following, having spent a day at Urarinas, and another at San Regis, and having been under the necessity of delaying his voyage for several hours, on account of the tempests which the winds are apt to excite on the waters of the Maranon. At the time when he associated himself, in his parochial dis-
- ↑ The Pachitea originates in 10 degrees 46 minutes, in the vicinity of the fort named Quiparacra. It runs to the east; and afterwards declines to the north, forming the river Pozuzu. It follows the latter direction for a certain space, and then recovers the former, which it preserves until it reaches the confluence and port of the Mayro. With this river, and with that of the Piechis, which flows into it below, it again winds to the north, and enters the Paro.
13 degrees of latitude, it throws off a branch, in an eastern direction, which enters an extensive lake, named Roguaguado, having an extension of upwards of ten leagues E. W. and of five leagues N. S. From the eastern side of this lake rises an arm which runs to Marmore; and in a northern direiction three others are thrown off. The one which has the greatest tendency to the west, is named Yata the first; the middle one, Tamayaquibo; and the eastern one, Yata the second. These branches following a northeast course, are without doubt the rivers Yutay, Tefe, and Coari, which, after the Ucayali, empty themselves into the Maranon [Condamine, l. c. p. 94]. The Beni, having supplied this arm, flows until it incorporates itself with the Apurimac, into which it enters with an aperture of half a league, and with the name of Faro. This communication has therefore produced the errors of our geographers relatively to the Beni, which is justly considered, by the above-mentioned father Rodriguez Tena, as the principal branch of all those that compose the Maranon.
