to foul them in the least ; so that I have occasion-

I fancy Monkeys sometimes go on day after day 
along the banks of a river, their rate of progress 
depending on the quantity of food they find to eat 
and waste. I have watched them at this in a strip 
of Mauritia palms, which stretched for a distance 
of some days' journey along the banks of a river. 
The Chorro (Barrigudo of Brazil), a monkey of 
the hot plain, sometimes ascends the slopes of the 
Andes to 5000 or 6000 feet, apparently to eat

An Indian will tell you at what time of year 
certain fruit-eating fowls are to be met with on the 
banks of a river, and at what time they must be 
sought for deep in the forest. I remember coming 
on a flock of one of the small Turkeys called Cuyubi
