308 Recognition in America 



Eduard Fernow, Filibert Roth, and others of the Division of 

 Forestry had recognized the need and worth of such study, and 

 had their scientific program of timber physics, wood chemistry, 

 and forest products investigation been brought to full fruition, 

 doubtless forest tree diseases would have been sooner more fully 

 investigated in this country. 



Smith always had been interested in reforestation for Michigan ; 

 and in 1898 a review in the American Naturalist " of Roth's study 

 of " Forestry Conditions and Interests of Wisconsin " was further 

 proof of this interest. Ecological research, coordinated with the 

 study of plant physiology, was only being developed in this 

 country when he reviewed George P. Merrill's " Notes on the 

 Geology and Natural History of the Peninsula of Lower Cali- 

 fornia " "'^ and Milton Whitney's " Preliminary Report on the Soils 

 of Florida." ^^ 



In 1890 he had been told by Spalding that Roth had done " an 

 admirable piece of work on the Ascent of Water in the Stems 

 of tall trees." Under Spalding, Roth had studied not only plant 

 physiology but also fungous diseases of plants. Later he taught 

 diseases of forest trees at the New York State College of Forestry 

 at Cornell University. 



Fernow and Roth encouraged vonSchrenk when he began his 

 studies of diseases of cypress and pine. At first, von Schrenk's 

 examinations were more mycological and descriptive than the 

 results of experimental investigations made in a laboratory espe- 

 cially created for the study of forest tree diseases. In 1893 he had 

 graduated from Cornell University where he had studied under 

 Atkinson; and the next year had secured a master of science degree 

 under Farlow who, it will be recalled, had published as early as 

 1879 on " Diseases of forest trees." 



At Harvard, under the leadership of Charles Sprague Sargent 

 of the Arnold Arboretum, forest investigation attained promi- 

 nence during the 1880's owing largely to his important study of 

 American forest trees and forest-tree distribution for the Tenth 



author, has revealed that he regards the beginning of his career as an American forest 

 pathologist when he pubUshcd his study, Note on Tubercularia pezizoidea Schwein.,
