Note 2 — Chapter I · INTRODUCTORY.

As I shall have occasion, in speaking of routes, to refer again to this river, I would like to draw particular attention to it, simply stating here, however, that all who have penetrated into the Montaña to the northward and eastward of Cuzco, agree in reporting a large and navigable river arrived at soon after clearing the skirts of the mountains. Different tribes of Indians inhabit its banks, and I presume it is on this account that so many different names—such as Amarumayo, Mano, Tono, Inambiri, Guariguari, Cachihuara, and Madre-de-dios—have been given it.
