INDEX. 



The full table of contents and the selection of running heads appear to make it unde- 

 sirable to index subjects. The chronological-alphabetical arrangement of abstracts in 

 Chapters II, IX, X, and XIII Ukewise seems to render unnecessary the indexing of 

 authors' names. In the index, communities are Usted under their respective dominants 

 and the latter thus serve to make available all material on any climax or community.
