4 INTRODUCTION 



American Beaver and His Works " (published in 

 1868 by J. B. Lippincott & Co.), Horace T. Mar- 

 tin, F.Z.S., &c., for " Castorologia, or the History 

 and Traditions of the Canadian Beaver" (1892), 

 Ernest Thompson Seton for "Life Histories of 

 Northern Animals," and Enos A. Mills for '* In 

 Beaver World" (1913), and to the Jesuit fathers. 



For the photographs which illustrate this volume 

 I can but say that I have done my best, and have 

 never spared myself in my efforts to get the most 

 satisfactory results. Some of the photographs of 

 the animals themselves have been shghtly re- 

 touched. It is my first offence in this direction, 

 and has only been done because after careful con- 

 sideration it seemed so very necessary. The reader 

 will never reahse the amount of labour that has 

 been devoted to securing the pictures given, for 

 they are illustrations rather than pictures. Let 

 him therefore pass over their defects with a kindly 

 consideration and not be too severe if in the text 

 he finds statements which do not agree with his 

 own ideas and experiences.
