PREFACE. xi 



For figures 97, 98, 108, 144, and 158 we are indebted to 

 Dr. Hiram Bingham, and figures 83, 109, 130, and 131 are 

 from photographs belonging to the New York Zoological 

 Society and were taken by Mr. E. R. Sanborn. All the 

 others were taken by ourselves with a Graflex Camera and 

 27-inch Goerz lens, and a pocket Kodak, both 4 by 5 in 

 size. 



The first two chapters appeared in their original form in 

 " Harper's Monthly Magazine," and the third chapter in 

 " Recreation/' 



Our thanks are due to Dr. William T. Hornaday, Direc- 

 tor of the New York Zoological Park, for the leave of absence 

 which made possible these expeditions. 



Three appendices have been added. The first is a 

 classified list of the birds, with their scientific names, which 

 are mentioned in the book; by no means a complete list 

 of those observed. Reference to it is facilitated by the 

 superior numbers affixed throughout the text to the names 

 of the birds. The second appendix gives the native Guianan 

 names of the commoner species of birds. The third is a list 

 of the insects observed at Hoorie which have been identified 

 up to the present time. 



\\ herever in this volume it has seemed best for any reason 

 that certain chapters should be written by one of the authors 

 alone, the writer's name has been given at the head of the 

 chapter. In all chapters not thus designated the authors 

 have collaborated. .
