NOTE 



With three exceptions these chapters have appeared in the pages 

 of The Atlantic Monthly, and I pubhsh them through the kindness of 

 the Editor, Ellery Sedgwick. "Hoatzinsat Home" is adapted from 

 a title in my Tropical Wild Life, Volume I, published by the New 

 York Zoological Society, which deals with the more technical results 

 of study at the Research Station. The illustrations are from my 

 own photographs, except the frontispiece and those facing pages 

 162, 186, and 268, which were taken by Paul G. Howes. All the 

 chapters dealing with the jungle relate to Bartica District, British 

 Guiana, except X, which refers to Pard at the mouth of the 

 Amazon.
