in fact, he finished his seventeen pa^es of manuscript during the 

 morning of the day it was given. He expected to find unly eiglu 

 or ten persons in attendance. But when he got to the Jardin des 

 Plantes he found " about 75 persons, and some very distinguished 

 ones ■' awaiting his lecture. The occasion was the first meeting 

 that year of the Socicte de Pathologic Vegetalc et d'Entomologie 

 Agricole de France, and among those present were Dr. Roux, Dr. 

 Calmette, Dr. Magrou who when Smith first called at the Pasteur 

 Institute was away on vacation, Dr. Mangin, director of the 

 Museum, Dr. Molliard of the Faculty of Sciences, Dr. Foex, 

 Dr. Marechal or-Marchal (Smith spelled his name both ways), 

 Dr. Bertrand of the Academy of Science, President Radais of 

 the college of pharmacy, Dr. Vayssicre, Dr. Patouillard, Dr. 

 Loubet, Drs. Fron and Maublancc, Dr. Mesnil, Professor Bouvier, 

 and others of " the best known men in Paris." Mme Lemoine 

 algologist, was also there. Dr. Smith exhibited his crown gall 

 photographs, read his address slowly, received the " minutest 

 attention," and was " applauded liberally." Jubilantly he wrote 

 his laboratory co-w^orkers: " ' On Crown gall ' ^^ is to be printed 

 and I have been asked to talk again on our return from Italy, next 

 time on the general subject of bacterial diseases of plants." 



Dr. Magrou and Dr. Pinoy of the Pasteur Institute asked to see 

 again his crown gall photographs. He had met Pinoy when on 

 his 1913 journey. In the conference which soon took place were 

 also Foex, C. R. Hursh, assistant to Professor Elvin Charles Stak- 

 man of the University of Minnesota and now studying for a year 

 with Magrou, and Dr. Jean Dufrenoy who spoke English and 

 occasionally served as an interpreter. Pinoy showed Smith " sec- 

 tions of a crowngall tumor on Pelargonium made with the hop 

 strain of Bacterium tumefaciens " obtained from Smith's labora- 

 tory. He wrote in his journal: '^" " These w^ere stained in Riker's 

 way with very dilute stain, and it really looks as though he had 

 succeeded in staining the bacteria inside the cells. He finds none 

 in the intercellular spaces, nor in most of the proliferating cells, 

 but a few cells of rather large size are full of short rods which 

 may be the bacteria, in which case surely there is action at a
