VEGETATION OF THE PEAK DISTRICT.

Vegetation of the Peak District. By C. E. Moss, B.A., D.Sc., F.L.S., &c. (Cambridge University Press. 12s. net.)—It will be enough to call the attention of botanists to the publication of this detailed and laborious contribution to a special branch of their science. Dr. C. E. Moss is already well known as a worker at phytogeography and also to those at Cambridge as the curator of the University herbarium. Ecology is now recognized as a branch of botany worthy of attention. This survey of the plant communities of the Peak district deals with an exceptionally varied and interesting region. Dr. Tansley has already given us the first general sketch of the plant formations and associations of the whole British Islands. The British Vegetation Committee are working at the same subject. Dr. Moss now gives the result of a, botanical survey of the southern Pennines begun in 1903. The study of vegetation is a very different thing from com- piling a flora. Dr. Moss's account of the plant associations and their relation to soils is an excellent piece of work. There are good maps, man,y well-selected photographs of types of vegetation, and a bibliography.
