go into such extensive tests as h'ave been outlined by the speaker- 

 Large cylindrical traps used on the college farm caught immense num- 

 bers of flies. Although we caught twelve to fifteen cjuarts each week 

 on the college general farm, we could not discover that the destruction 

 of this number produced any appreciable 'diminution. It seems to 

 us that traps are almost useless in such campaigns, and that the elim- 

 ination of breeding places is all-important. In the city fly control work 

 this must be brought about by the establishment and maintenance of 

 a good sanitary police force. 



Mr. J. G. Sanders: Of all the baits I have used for house-flies, 

 the best I have discovered is milk and formalin. It is more effective 

 if milk is allowed to sour h)efore the formalin is added. 



Mr. Z. p. Metcalf: In my laboratory I have a sink about twelve 

 feet long from which the water does not drain properly. Vessels con- 

 taining formalin solution are often exposed in this room and on days 

 when the sink becomes dry the flies drink the formalin from these ves- 

 sels and are killed. When the water remains )n the sink they do not 

 touch the formalin and no mortality results. In West Raleigh the 

 people are able to control the house-flies by not giving them access to 

 water. 



In another room where there was a drinking fountain Hies were very 

 troublesome and it was impossible to kill them with the milk and 

 formalin mixture. After the fountain was removed large numbers 

 were destroyed by using this mixture. 



President P. J. Parrott: We are greatly favored this morning 

 by the presence of Dr. L. 0. Howard who will present the next paper, 

 entitled "The Education of the Entomologist in the Service of the 

 United States Department of Agriculture." 



THE EDUCATION OF THE ENTOMOLOGISTS IN THE 

 SERVICE OF U. S. DEPARTMENT OF AGRICULTURE 



By L. O. Howard , 



This paper has no connection Avith the excellent series of papers 

 presented before this Association on the training of an economic 

 entomologist, since it does not in any way attemjit to point out the 

 necessary lines of education for one entering the government service. 

 It is simply an effort to indicate the educational institutions at which 

 the. men who have entered the service received their training. I have 

 the facts about 2()() of these individuals, and, entering into the matter 

 without any preconception of the result, I must confess to much sur- 

 prise at the great number of institutions represented (64 American
