ACKNOWLEDGMENTS 
In the preparation of this book I have been encouraged 
by the assistance, so willingly given, of many of my col- 
leagues and friends who have furnished data or have other- 
wise helped me in my endeavour to make the volume both 
accurate and informative. It would be impossible to men- 
tion every one to whom I am indebted for assistance, but 
I should like to express here my grateful appreciation of 
the assistance of the following: Many of my colleagues 
in the government service, particularly Mr. James White, 
Assistant to Chairman, Commission of Conservation; Mr. 
J. B. Harkin, Commissioner of Dominion Parks, and Doc- 
tor R. M. Anderson and other members of the staff of the 
Geological Survey; the officers in charge of the game-pro- 
tective service of the various provinces, and Mr. F. Ker- 
mode, Director of the Provincial Museum, Victoria, B. C.; 
Doctor Henry Fairfield Osborn, President of the American 
Museum of Natural History; Mr. E. W. Nelson, Chief of 
the United States Biological Survey; Doctor W. T. Horna- 
day, Director of the New York Zoological Gardens, the 
staunch defender of the wild life of this continent, who 
has been a constant source of help and encouragement; 
Mr. Charles Sheldon; and many others. The courtesy of 
Rudyard Kipling, in giving permission to use the quotation 
from his poem, “The Feet of the Young Men,” is hereby
