houses. Because other mosquitoes don't find the way in, many 

 persons are under the impression the Anopheles do not, but they 

 do. We can find them in the houses. 



President Meyers — That is very valuable information. Any- 

 body who desires screens wants to know how many apertures 

 to the square inch are necessary. 



Secretary HeadleE — May I ask the speaker what effect, if 

 any, the Paris green had on the top-water minnow? 



Mr. Le Prince — The men in the field have looked for dead 

 or sick minnows, I might say, for weeks after the application of 

 the Paris green and can't find them. To date we have not been 

 able to find any. Experimental work is being continued and if 

 we find any we shall let everybody know right away. 



President MeyErs — The next speaker has been coming to 

 these conventions from year to year to speak to us and to add 

 to our* information the results of his department. No speaker

 their sure instincts, are able to prosper as they do, man would 

 better turn the world over to the insects. That is a pessimistic 

 view, however, which I am sure we do not share. 



Mr. Le Prince and I have attended your meetings for several 

 years, but have never talked about the New Jersey mosquito 

 problem. It seems that your own intense interest in mosquitoes 

 here in New Jersey has been so great that it has made you in- 

 terested in all mosquito work, but I am greatly pleased to see 

 that Mr. Le Prince has brought out for the first time that the 

 work that is going on in other parts of the country has an imme- 

 diate practical importance for you here in this state. He has 

 shown that the prevalence of malaria in the South reduces the
