PREFACE xv 



"But it is necessary and proper now to advertise this new 

 calling soil-healing and its needs to young people who are 

 wondering what to do with their lives. There is work here for 

 you, if you will get the training. It will never make you rich, 

 but it will support you; and it is real, vital, and absorbing 

 work." 



Our sincere thanks are extended to a number of government 

 departments for their generous cooperation in giving us infor 

 mation. In the case of the Forest Service, the Soil Conservation 

 Service, the Park Service, and the Indian Service, they pro 

 vided the facilities to see at first hand many of the aspects of 

 land use which would otherwise have been available only in 

 printed reports. We are also indebted to these agencies for the 

 criticisms which have helped to clear up many doubtful points. 

 Among the many other government agencies to which the 

 authors would like to express their indebtedness are the Bureau 

 of Agricultural Economics, the National Resources Commit 

 tee, the Division of Grazing, the Agricultural Adjustment Ad 

 ministration, the Farm Security Administration, Bureau of 

 Mines, Biological Survey, Bureau of Fisheries, Geological Sur 

 vey, and the War Department. In a like measure, we are also 

 grateful for the assistance of Colonel William Greeley and Cap 

 tain John Woods of the West Coast Lumbermen's Association, 

 who provided us with information which was vitally necessary, 

 and to Professors A. C. Cline and P. R. Cast of the Harvard 

 Forest for valuable suggestions. Thanks are owing to the Har 

 vard School of Public Administration for the use of research 

 materials financed by the Social Science Research Committee.
