Nanay
The
Nanay is tributary to the
Amazon River west
of the
Napo. It belongs entirely to the lowlands, and is very crooked, has a slow current and divides much into canos[1]
and strings of lagoons which flood the flat, low areas of
country on either side. It is simply the drainage
ditch
of districts which are extensively overflowed in the rainy
season. Captain Butt ascended it 195 miles, to near its source.
[1] A cano, like furo, is a kind of natural canal; it forms a lateral discharge for surplus water from a river.
