260 NOTES AND COMMENT 



junipers. The treatment in this bulletin is less detailed than in the 

 Pacific Slope volume and is more popular, which will make it less val- 

 uable to the people — that is to the people who will actually have use 

 for it. The illustrations of the details of foliage and fruit are splendid, 

 but the pictures of the trees themselves are wretched cuts that might 

 well have been replaced by half tones from some of the many fine nega- 

 tives in the possession of the Forest Service. The distribution of some 

 of the trees is shown by maps, which are executed with painstaking 

 accuracy but are almost too small to be of more than very general use. 

 They are, at least, a poor substitute for the actual lists of occurrence 

 found in the Pacific Slope volume. 



Dr. C. C. Adams has published a brief Outline of the Relations of 

 Animals to their Inland Environments, which is an eloquent plea for 

 the dynamic study of animal associations. An extended report by 

 him on the ecology of the invertebrates of prairie and forest is about 

 to appear as a Bulletin of the Illinois State Laboratory of Natural His- 

 tory. In June Dr. Adams entered on his new post as Forest Zoologist 

 in the College of Forestry at Syracuse University, and has since been 

 organizing work on the animal ecology of New York.
