Newcombe had collected funds from former pupils of Dr. 

 Spalding to erect the memorial tablet which in the Natural 

 Sciences building of the University of Michigan honors the work 

 of this great teacher. Spalding, interested in applying modern 

 investigation tecliniques of plant physiology to ecology, had 

 resigned from liis university professorship and become a resident 

 investigator at the Carnegie Institution's Desert Botanical Labora- 

 tory at Tucson. Smith's continued interest in ecology was shown 

 in 1906 when in Berlin he sought out Georg Volkens, author of a 

 " beautiful ecological paper on the Egyptian and Arabian desert," 

 a study which had excited his admiration and " greatest interest " 

 and which he thought " a model in its way." In 1906 Smith had 

 something to do with honoring an American botanist who had 

 helped to coordinate research in plant physiology and ecology — 

 W. F. Ganong. That year the Society for Plant Morphology 

 and Physiology was being merged with the Botanical Society of 

 America, and E. C. Jeffrey, retiring president of the former 

 organization, asked Smith, on behalf of its members, to present a 

 silver cup to Ganong in appreciation for his many years of service 

 as their secretary-treasurer. Farlow was first asked, but neither 

 Smith nor the first president of the organization could attend the 

 meeting at which the presentation was made. Dr. Ganong subse- 

 quently was elected president of the Botanical Society of America, 

 and Smith followed him in office. 



In 1910 Smith, as president of the Society, arranged a sym- 

 posium on plant pathology for the Minneapolis meeting of that 

 year. As an ex-officio member of the sectional committee, he was 

 requested by Dr. H. C. Cowles of the department of botany of 

 the University of Chicago to suggest " topics and participants " 

 for the program of Section G. 



L. R. Jones agreed to open the discussions at the symposium 

 on plant pathology. He had served as the first president of the 

 American Phytopathological Society and, following him, Frank 

 Lincoln Stevens, professor of botany and vegetable pathology at 

 the North Carolina College of Agriculture and Mechanic Arts, 

 was to preside at the Society's second annual meeting, also to be 

 at Minneapolis. In 1912 Stevens was to go to the University of
