viii PREFACE TO THE REVISED EDITION 
In the preparation of the first edition of this book, the author 
gratefully acknowledged assistance which he had received from Florence 
Merriam Bailey, J. A. Allen, and Ernest Thompson Seton, and he 
now desires to express his indebtedness to Waldron DeWitt Miller for 
aid in reading the proof of the present edition, and to Henry W. Henshaw, 
Chief of the Biological Survey, for permission to reproduce the faunal 
map appearing on the cover pages. 
It is proper, in closing this preface, for the author to express the 
pleasure and gratification which the reception of the first edition of 
the “Handbook” has given him. So far as circumstances permit, he 
has endeavored to make this new ‘Handbook’”’ worthy of the praise 
which has so generously been accorded its predecessor.
