TO 



ALBERT F. POTTER, 



Associate Forester and Chief of Grazing 

 United States Forest Service, 



who, through his practical experience 

 on the western ranges, and genius for 

 organization, built up from the very 

 foundation, without precedent or guide, 

 a system of controlled grazing on the 

 national forest ranges, that will always 

 be a monument to his ability, judgment 

 and foresight.
