A study of the effects of large bodies of impounded water on 

 the production of malaria has been carried on for the past three 

 years. Valuable data have been secured and methods of min- 

 imizing this effect when it exists have been worked out and 

 applied. 



Nor is there time to more than allude to what has been done 

 to spread a knowledge of malaria and of its control among the 

 * people. Much has been done in, this line by bulletins, leaflets, 

 lectures, lantern slides, exhibits, etc., and it is bearing some fruit. 



I pin my faith, however, on two educational methods: (ij 

 Teaching the basic facts of malaria conveyance and control in 

 the schools of the malar io-us districts, so that the children may 

 grow up with definite and correct knowledge on this subject; 

 and (2) the demonstration of malaria control. For the adult 

 population there is no method of equal educational value. The 

 teaching I speak of is being quite generally done in the malarious 

 districts, and of the demonstrations I have already spoken. 



As an educational means the various bulletins issued by the 

 Public Health Service and the State are of value. Some of those 

 on screening, oiling, draining, etc., for malaria control are really 

 handbooks for one undertaking to do these things, which are 

 by no means so simple as they may seem, and should be very 

 valuable. 



President Darnai^i^ — We have with us this evening another 

 guest of international reputation, a man whom we will look to 

 as being the last word in entomology. In introducing him I 

 wish to say that we are in need of guidance in the matter of 

 adding the work of fly control to the list of duties now performed 

 by the County Mosquito Extermination Commissions. There 

 exists among us a wide divergence of opinion as to the wisdom 

 of such a course, and we hope that the next speaker will add to 

 the data we already have bearing on this subject. 



It gives me^great pleasure to introduce Dr. I^. O. Howard, 

 Chief of the Bureau of Entomology of the United States De- 

 partment of Agriculture. 



Dr. ly. O. Howard — Mr. Chairman, ladies and gentlemen : 

 I think it would be very unwise indeed for the State of New
