LIST OF REFERENCES. 



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

 cerned with methodology. A few references are given to descriptive works in which 

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

 of the problem to lie met by the future ecologist is emphasized. No attempt has 

 been made to prepare a complete bibliography, and the convenience of the average 

 student has received considerable weight, in avoiding, especially, foreign-language 

 articles.
