The illustrations for this book have been made from photographs 

 taken by Mr. Howard T. Middleton, Mr. J. Fletcher Street, Mr. 

 William L. Baily, and Mr. A. D. McGrew. The author wishes to 

 express his appreciation here of the skill, knowledge, and patience 

 which have made such photographs possible. In some of those taken 

 by Mr. Middleton, tamed, caged, or mounted specimens have been 

 used as models. In others he has persuaded wild animals to photo- 

 graph themselves by various ingenious devices.
