viii PREFACE 



Because of the limitations of the camera, several thousand dollars have been ex- 

 pended upon the beautiful drawings by Messrs. J. Carter Beard, Carl Rungius, Edmund J. 

 Sawyer and a few other artists, which adorn as well as illustrate this work. In addition 

 to these, about one hundred and sixteen particularly excellent photographs have been 

 made, of specially selected subjects, by Messrs. Elwin R. Sanborn, Ernest F. Keller, 

 W. Lyman Underwood, R. J. Beck, and a few other experts in animal photography. 

 With but very few exceptions, the illustrations which appear in this book have been made 

 expressly for it, and now appear for the first time. The author is indebted for the loan of 

 several from the publications of the New York Zoological Society. 



Now that the last page save the preface has been set up, locked fast and turned into 

 a plate of cold metal, the hour for regret has struck. I know that my proof-reading 

 has not been perfect, and that various errors may be found by those who watch for 

 them. In view of the patient and even tireless efforts and the generous expenditures 

 which Messrs. Charles Scribner's Sons have bestowed upon this volume, the author deeply 

 regrets that his own share of the work is not as perfect as theirs. For the reader's 

 sake, also, he wishes that he could have done better.
