Last Work. Final Honors 643 



August 16 of that year. 'I'licrc were between ei^ht and nine 

 hundred registrants, and, t)f these, fully one-eighth were foreign 

 delegates. Dr. Smith found the occasion " the most delightful 

 scientific gathering [he had] ever attended." '"^ His great friend, 

 Dr. Liberty Hyde Bailey, was president and presiding chairman of 

 the congress. He introduced Smith on the night he gave his 

 address to an audience of about three hundred persons. The 

 address, well received, required two hours in presentation and was 

 illustrated by forty-five lantern slides. 



Smith one day attended a luncheon of the nine members present 

 of the National Academy of Sciences. He spoke on "' Dr. Jones, 

 the man," at a dinner given in honor of Professor L. R. Jones and 

 at which the honored guest's portrait was presented to the Uni- 

 versity of Wisconsin and a set of twenty-nine bound volumes of the 

 collected works of his students given him. Among several other 

 important events was a luncheon, which Smith also attended, 

 honoring twenty-two foreign botanists at the congress. He be- 

 lieved that " great credit " for the congress' effectiveness should go 

 to Dr. Whetzel, chairman of the committee on local arrangements, 

 and he visited his laboratories of plant pathology on the last day. 

 After the congress. Dr. and Mrs. Smith took a short journey 

 through points in New York State to Toronto where he enjoyed 

 again visiting with Professor Leslie C. Coleman who was teaching 

 at his alma mater after having returned from Mysore, India, where 

 he had been director of agriculture. 



At the congress, Dr. Smith became acquainted with Professor 

 B. Nemec from Czechoslovakia who showed him " very beautiful 

 stained slides of root-nodules of Legumes and leaf teeth of 

 Ardisia " and who claimed that he had " stained the bacteria in 

 crown gall [which] like B. radicicola are both between the cells 

 and inside of them." While in London he had been told of a 

 method of staining, used by Dr. Murray, which might be applied 

 for crown gall bacteria.''" He wrote down Professor Nemec's 

 formula. ^*^^ The papers on pathology at the congress which appear 

 to have interested him the most were on " Filterable virus diseases,

^•"^ Diary, Aug. 21, 1926. Nemec had read a paper before section C, Cytology, on 

 The mechanism of mitotic division. Another paper which Smith marked for hearing 

 at this section meeting was Dr. Harper's, The structure and functions of plastids, 

 particularly elaioplasts.
