NOTES AND COMMENT 149 



The most interesting general feature of the book is a description of the 

 grape growing regions of the United States and their climatic features. 

 The narrowly localized character of the grape industry in New York, 

 Ohio and California is shown to be due to topographic features which 

 assure a long growing season and a sunny summer. 



E. Blatter and F. Hallberg are publishing in the Journal of the 



Bombay Natural History Society (Vol. 26) a Flora of the Indian Desert . 

 Their annotated list of species is given additional importance by the 

 insertion of numerous illustrations of vegetation in the little known 

 and extremely arid states of Jodhpur and Jaisalmer, in the western 

 Rajputana. Extended areas of moving sand are extremely poor in 

 vegetation. The prevailing open stand of low bushes is chiefly made 

 up of species of Leptadenia, Prosopis, Acacia, and Aerna. In moist 

 situations the characteristic trees are Salvadora, Gymnosporia, Capparis 

 and Zizyphus.
