NOTE 



The compilers are indebted to W. A. Duerr of the Southern Forest Experiment Station, U. S. Forest 

 Service, for acting as advisor and consultant from inception to completion of this bibliography. 

 Subject arrangement of contents, and terminology used in subject classes largely are his work. 

 During the last stages of compilation, H. R. Josephson of the Division of Forest Economics, U. S. 

 Forest Service, generously acted as reviser and consultant. 



In most cases, when an entry in the bibliography refers to a feature or report appearing at regular 

 intervals, only the latest issue is cited. Geographic subdivisions are governed in concept, but not 

 necessarily in nomenclature, by administrative regions set up in the U. S. Forest Service. Hence, 

 Missouri is considered a northern state in the body of the bibliography, where larger regional 

 arrangement occurs. 



The index lists trees, insects and fungi by common name. Tree nomenclature roughly corresponds 

 to that used in the Checklist of Native and Naturalized Trees of the United States, Including Alaska, 

 issued in revised form by the U. S. Forest Service in 1944. 



Call numbers given after each entry are those of the U. S. D. A. Library. For references in other 

 libraries the name of the library is given but not the call number. 



The list of Sources Consulted presents only those sources contributing a large number of independent 

 references. Many other separate lists and bibliographies appended to articles and books were checked 

 also. In addition to the libraries whose card catalogs proved most fruitful, seven other Washington 

 libraries, including the Library of Congress, were visited.
