Jersey to modify the present excellent mosquito law by attempt- 

 ing to include house fly control. The problem of house fly con- 

 trol is entirely different in that it is not concerned with the ex- 

 termination of far-flying species. It is more like the problem 

 of mosquito control in inland States. It would be absurd to pass 

 a law designed to control mosquitoes in inland States, for the 

 reason that the mosquito pest is not a State-wide problem under 

 such conditions, and the same reason applies tO' the house fly 

 problem in the State of New Jersey. 



While the house fly breeds principally in manure, it also breeds 

 in all sorts of filth. The practice of measures of good sanitation 

 will bring it under control. Box privies must be eliminated ; all 

 garbage regularly and promptly removed. Horse manure must 

 be regularly removed and spread on the land in such a thin 

 layer as will promptly dry out. Bulletins covering the various 

 phases of house fly control are issued at Washington, and may 

 be had for the asking. In view of these conditions it would 

 seemi unnecessary for me to attempt to cover the details in the 

 course of this talk. 



I wish to say that it has been a great pleasure to meet with 

 you again. I have made it a point to attend every meeting of 

 this Association from the beginning, and hope tO' continue to do 

 so in the future. I have a few slides that may be of interest 

 to you, which will now be thrown on the screen. 



President Darnali, — The next speaker whom I shall intro- 

 duce needs no introduction, he is so' well known to us all and 

 he is so well known all over the State. It may be said he has 

 a good many things besides mosquitoes, however, to contend 

 with, for he is the Director of the Agricultural Experiment 

 Station at New Brunswick. 



I take great pleasure in introducing Dr. Jacob G. Lipman.
