Oi- THo Science of Plant Bacteriology 309 



Census. When the first prospectus for the influential periodical, 

 Garden and Forest, was sketched, Sargent submitted it to Fariow 

 who was to have chart^e of cryptOL;amic botany. " Garden and 

 forest," this read, " will be devoted to Horticulture in all its 

 branches. Garden Botany, Dendrology and Landscape Art. It will 

 present the results of the latest studies on Plant Diseases and 

 Insects Injurious to Vegetation. It will give special attention to 

 the subject of Forestry." 



After studying forest tree and other plant diseases with Fariow, 

 von Schrenk in 1893 went to Europe and studied with Robert 

 Hartig, " father of 'forest pathology." '* He returned to the 

 United States and became an instructor in botany at the Manual 

 Training School of Washington University and instructor of cryp- 

 togamic botany at the Shaw School in St. Louis. During the last 

 years of the century, when the federal department of agriculture 

 established its Mississippi Valley Laboratory at St. Louis, he was 

 appointed pathologist in charge, and his work included inves- 

 tigating timber diseases and timber preservation. Moreover, in 

 1898, at the university, he taught a course for civil engineers in 

 bacteriology, particularly as applied to water problems. 



Smith's interest in forest pathology appears to have been first 

 expressed in 1892. He had read a paper by Fariow and on 

 January 5 wrote: " Your paper on Diseases of trees likely to 

 follotv Mechanical injuries is so good that it ought to have a 

 wide circulation. As a lover of trees it interested me greatly." 

 He wanted to arrange to have the Michigan Horticultural Society 

 reprint it. 



His papers presented to Section G at the 1898 anniversary 

 meeting of the American Association for the Advancement of 

 Science were three: " Potato as a Culture Medium with some 

 Notes on a Synthesized Substitute"'^''; "Some Little Used Cul- 

 ture Media, which have proved valuable for Differentiation of 

 Species "; ^" and " Notes on Stewart's Sweet Corn Germ, Pseudo- 

 monas Stewarti, new species." ®^
