that train. We proceed into la France. I regard through the fenetre. I 

 say, ' Is it posseehle that this is agriculture? ' I reply to myself, ' No, 

 it is not posseeble ; it is a gigantesque checker-board.' We are arrive in 

 Paris. I enter a taxi. Whisht ! J'etais chez moi. I had sought that 

 Paris was a great city; it is not. Where are the skyscraj^rs? They 

 do not exist. In going to America I have lost part of my supreme 

 admiration for my city and my country." 



He had learned his English the year before at the Berlitz School 

 in anticipation of a visit to London to attend the congress on sleep- 

 ing sickness and the Seventh International Congress of Zoology held 

 in Boston in the summer of 1907. As he told me when I met him on 

 the Channel steamer in the spring of that year, " I have studied the 

 English in the School Berlitz, and they tell me I now speak it 

 parfaitement." 



Blanchard's student and successor. Dr. E. Brumpt, the author of 

 a famous " Precis de Parasitologic," I first met at Roscoff in 1912. He 

 had a laboratory there and was studying various phases of parasitism. 

 He also is a man of many attractions and a worker of the Blanchard 

 type. 



Etienne Roubaud is a younger man who for many years has had his 

 laboratory at the Institut Pasteur. I met him first in Bouvier's lab- 

 oratory in the Museum of Natural History. He was then studying 

 black flies (Simulidae). Later he became famous through his writ- 

 ings and investigations, and I have since talked with him in his 

 Pasteur laboratory and have corresponded with him on many subjects 

 connected with medical entomology. 



A most interesting experience with the Institut Pasteur occurred 

 many years ago. The brothers Sergent in Algeria were much con- 

 cerned with a trypanosomc disease of camel-s, carried by Tabanid 

 flies. They wrote to me in Washington, inquiring whether there was 

 in the United States an effective natural enemy of Tabanids. I wrote 

 them at once about the giant wasp known as Moncdula Carolina, and, 

 largely through the help of Wilmon Newell, then in Louisiana, a 

 large nesting ground of the was]> was discovered on the. shore of the 

 Gulf of Mexico ; pupae were collected ; photographs were taken show- 

 ing the physical conditions of the region and the exposure, and the 

 pupae were sent under refrigeration to the Institut Pasteur at Paris. 

 The Sergents had them conveyed by hand from Paris to Algeria and 

 placed in the sand under conditions as closely resembling those in 

 their original Louisiana habitat as possible. During this oi>eration I 

 visited the Institut and had a formal interview with Roux, the Direc- 

 tor, Mesnil, and several of the other experts. I took an interpreter
