ACKNOWLEDGMENTS AND RESPONSIBILITY 



I have stated publicly the opinion that no man could, from his 

 own resources alone, successfully write a book on the total relations 

 of man to his environment. There are too many sciences involved. 

 Having, with much travail and the aid of a corps of obstetricians, 

 brought forth the following brain child, I have found no reason 

 to change my mind. It is with deep gratitude that I acknowledge the 

 help of the following men: 



Clyde H. Jones of the Ohio State University Department of 

 Botany, who has saved me from many a technical error in his field ; 



Charles Dambach of the Ohio State University Department of 

 Zoology, whose grasp of the field of organic resources is exceeded by 

 few; 



William A. Albrecht, Chairman, Department of Soils, University 

 of Missouri, outstanding pioneer in the relations of soils to health ; 



H. A. Morgan, Director of the Tennessee Valley Authority, and 

 the following members of the TVA staff : Rosslyn B. Wilson, Writer ; 

 William M. Landess, Head, Program Exposition Unit; E. 0. Fippin, 

 Agriculturalist, Program Review and Analysis staff; Paul E. Johnson, 

 Nutritionist, Tests and Demonstration Staff all of the Agricultural 

 Relations Department; Ira N. Chiles, Area Education Officer, Reser- 

 voir Properties Department; 



E. A. Johnson, Acting Chief, Range Division, Soil Conservation 

 Service ; L. E. Thatcher, Associate in Agronomy, and Wise Burroughs, 

 Department of Animal Industry, Ohio Agricultural Experiment Sta- 

 tion ; 0. D. Diller, Associate State Forester, Ohio Division of Forestry. 



To these men, and to innumerable others whose writings, re- 

 searches, and remarks have contributed to my still feeble grasp of the 

 complex landscape, I offer thanks for their help. 



It must be clearly understood that no one of those mentioned is 

 responsible for statements in this book, except when a direct refer- 

 ence is made. I have not in every instance agreed with their opinions 

 or with their interpretations of data. 



No apology is made for laying hold of the most advanced thinking 

 in the relations of man to the landscape. A few phases of those 

 relations may still be controversial. My stand on such questions is 

 deliberate. I choose boldness rather than the extreme caution of the 

 scientific and technical specialists because I do not believe that 

 modifications resulting from further (and needed) research will make 

 any great difference in the broad social conclusions now apparent.
