xii PREFACE 



great work has been done well and wisely. The 

 people of the Eastern States will soon realize that 

 a similar forest policy, already inaugurated in the 

 Appalachian and White Mountains, will mean 

 every bit as much to them. 



If I succeed only in a small degree to make my 

 reader appreciate the great significance of the Na- 

 tional Forest movement to our national economy, 

 I will feel amply repaid for the time spent in pre- 

 paring this brief statement. I am indebted to the 

 Forest Service for many valuable illustrations used 

 with the text, and for data and other valuable as- 

 sistance. To all those who have aided in the prepa- 

 ration of this volume, by reading the manuscript or 

 otherwise, I extend my sincere thanks. I am espe- 

 cially grateful to Mr. Herbert A. Smith and others 

 of the Washington office of the Forest Service for 

 having critically read the manuscript and for hav- 

 ing offered valuable suggestions.
