On the Putumayo, if a few Yuris are still met with, the Yahuas have abandoned the district to take refuge among some of the distant tributaries, and the Maoos have quitted its banks to wander in their diminished numbers among the forests of Japura.
The Tunantins is almost depopulated, and there are only a few families of wandering Indians at the mouth of the Jurua.

The Teffe is almost deserted, and near the sources of the Japur there remained but the fragments of the great nation of the Umauea.

The Coari is forsaken.

There are but few Muras Indians on the banks of the Purus.

Of the ancient Manaos one can count but a wandering party or two.
