LIST OF REFERENCES. 



The following citations to the literature of forest ecology are mainly those 

 concerned with methodology. A few references are given to descr'ptive works 

 in which the methods of obtaining the results are clearly brought out, or in 

 which the nature of the problem to be met by the future ecologist is emphasized. 

 No attempt has been made to prepare a complete bibliography, and the con- 

 venience of the average student has received considerable weight, in avoiding,. 

 especiallj r , foreign language articles.
