94 NOTES AND COMMENT 



The Geological Survey of South Dakota is continuing its work on 

 the biological features of that state, its most recent bulletin being a 

 report on Harding County, embracing a description of the vegetation 

 and a list of plants, birds, and mammals. Throughout the report 

 the grassland is unhappily alluded to as "steppe," a term which is not 

 properly applicable to any part of the United States. 



Dr. L. Cockayne, of Wellington, has published for distribution at 

 the Panama-Pacific Exposition a pamphlet of 35 pages describing a 

 large number of New Zealand plants suitable for cultivation in the 

 United States. 



Prof. Dr. A. Burgerstein, of Vienna, has completed a revision of 

 his well known text on the transpiration of plants, but states that he 

 will be unable to publish it until the close of the European war.
