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

 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

 them fell, the rest either took no heed or only 

 hopped on to another branch and recommenced 

 feeding ; and it was not until we had fired and
