viii PREFACE TO THE REVISED EDITION 



In the preparation of the first edition of this book, the authof 

 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.
