ACKNOWLEDGMENT 



Much credit is given to the many workers who participated in the 

 initial forest survey (1934-36) and subsequent reappraisals of resource 

 data upon which this report is based. In the initial survey J. W. Girard, 

 from the Washington Office, U. S. Forest Service, was especially helpful 

 in developing plans and procedures. Special mention is also made of 

 the men responsible for the various phases of the survey: H. C. Moser 

 who served as assistant to the author and was in charge of the compilation 

 of data; E. L. Lawson, chief of field parties; S. R. Gevorkiantz, in charge 

 of growth studies; and H. G. White, in charge of depletion studies. 



In the recent reanalysis of survey data, major contributions to this 

 appraisal of the forest situation were made by the following: Arthur 

 Horn, in charge of compiling production estimates, assisted by Dorothy 

 Keller, John Neetzel, Zigmond Zasada, and Waldo Sands; Paul Rudolf, 

 Russell LeBarron, William Kluender, and Howard Mayne, who com- 

 piled the ownership data; Clarence Chase and S. R. Gevorkiantz, Avho 

 were in charge of the computation of drain, gi-ov,th, and revised 

 inventory statistics. 



Valuable cooperation in compiling up-to-date estimates was given by 

 the following: Stanley Fontanna, George Mclntire, and members of 

 their staff, Michigan Department of Conservation; Fred Wilson, Wiscon- 

 sin Department of Conservation; H. G. Weber, James Gannaway, and 

 E. L. Lawson, Minnesota Department of Conservation; Joseph Donery, 

 American Forestry Association; H. Basil Wales and the Supervisors of 

 the Lake States National Forests; William Heritage, U. S. Office of 

 Indian Affairs; and U. J. Noblet, Michigan School of Mines.
