Now the mosquito, as we know, which carries yellow fever is 

 practically a cat and dog mosquito, a domestic mosquito. It lends 

 itself by its habits to eradication. And that is one reason why 

 they have found it pos'sible to eradicate the yellow fever mosquito in 

 those tropical countries. 



The malarial mosquito is a different kind. Its habits of flight do 

 not lend themselves to as easy disposal as the yellow fever mos- 

 quitoes. Consequently they have had a much more difficult proposi- 

 tion to get rid of the Anopheles mosquito than they had the yellow 

 fever mosquito. They have not particularly concerned themselves 

 except incidentally with salt marsh mosquitoes and other mosquitoes 

 which were not a menace to health, but which were simply a pest 

 for all the people in the family. I think that should be borne in 

 mind. 



But if we cannot compare the work done in New Jersey with that 

 done in the tropics — I feel that very heartily — it is certainly a won- 

 derful thing and we should not be discouraged in this work. But we 

 all know who have been in this work from the start that the mosquito 

 today in New Jersey is nothing like the pest it used to be before we 

 began the work. The results have been simply tremendous and we 

 must not be impatient. 



There is a little psychology in this thing that one should carry into 

 other walks of life, which tells me and tells many observers that 

 work which begins slowly and proceeds not too rapidly, in making 

 sure of the ground as you go on, thereby establishing a firm founda- 

 tion, is a good deal surer in its results than quick, flashy sort of 

 work. And perhaps it is a wise dispensation of providence for the 

 money givers of this state that we are not allowed to spend enormous 

 sums of money immediately ; but from the evolution of our work in 

 methods, the obstacles we have met, the changes in methods which 

 have been brought about through observation, of necessity have 

 been tremendous in the mosquito work in New Jersey. Our meth- 

 ods have changed entirely in many things in our state. 



Last night in the little paper that I read I called attention to the 

 wonderful optimism of Prof. Smith — 'Tn a few years New Jersey 

 will be mosquitoless" — and the method we should use, in his opin- 

 ion, is working practically to that end. We practically followed his 

 ideas from that time on and have changed them to meet new condi- 

 tions, always ready to take up a new thing when it offers better 

 results. 



So after all there is something, perhaps, in the slowness with
