The earth and its inhabitants .. . the mountains interminglesits waters with the Quillabainba to form the great Rio Ucayali. I The Quillabainba, flowing in a line with the lower valley, may be regarded asthe main upper branch of the system.

A well-marked parting-line between two perfectly distinct fluvial systems isindicated by the confluence of the Tambo with the Quillabamba at an elevation of8G0 feet above sea-level. Above the confluence the streams are in the nature ofmountain torrents, rushing wildly between their rocky walls, or disappearing iudeep romantic gorges ; below the mainstream flows sluggishly in a broad windingchannel, whose banks are everywhere covered with continuous forest growths.

All these watercourses descending to the Ucayali and to the Huallaga havebeen the object of numerous hydrographic surveys by Tucker, Werthemann andother engineers in the service of Peru.
