Past climates and climaxes are fully discussed (Chapter XII) 

 under the captions of botanic and zooic evidences, causes of 

 climatic changes, climatic cycles and finally the correlation of 

 climatic cycles and succession. The succession of plant popula- 

 tions in the various geological areas and periods forms the topic 

 for three additional chapters. 



The large number of well-chosen and excellent photographs 



add materially to the value of the book, which no working 



ecologist can afford to be without.

Grout's Moss Flora of New York City snd Vicinity* 



The study of the local flora of New York City and vicinity 

 has been one of the main activities of the Torrey Botanical Club 

 since its foundation and its members will welcome the appear- 

 ance of Dr. Grout's attractive booklet on the moss flora of their 

 region. Following so soon the publication of Taylor's "Flora 

 of the Vicinity of New York," which was limited to the spermato- 

 phytes and pteridophytes, it will not only stimulate the study 

 of the group of plants with which it is directly concerned, but 

 will also encourage the publication of other special local floras 

 covering the Hepaticae, fungi, algae, etc., of the region of New 

 York City. Dr. Grout's moss flora includes descriptions of the 

 families and genera, keys to the families, genera, and species, 

 notes on the habitat and known distribution of the species, 

 and very successful habit photographs of nineteen of the more 

 characteristic or interesting mosses of the local field.
