Progress in Mosquito Control in Greater New York 



BY EUGENE WINSHIP, SANITARY ENGINEER, DEPARTMENT OE 

 HEALTH, NEW YORK CITY 



I am very glad that I have another opportunity to be with 

 you and tell you of another year of splendid achievement in 

 mosquito-extermination work in Greater New York, despite 

 conditions in many respects far from favorable. 



In addition to a very wet spring which was most favorable to 

 mosquito growth, over three hundred water-pumping stations 

 in Greater New York were shut down, and, as a consequence, 

 swamps appeared where there had been none for many years 

 before. This condition would doubtless have been a source of 

 worry had I not reflected that the splendidly thorough work on 

 the Jamaica Bay marshes during 1916 would have so reduced 

 the number of mosquitoes in Queens and Brooklyn that the new 

 lot from this cause would scarcely be noticed before I could 

 complete the work in Brooklyn and Queens. 



Early in January the work on the four-million-foot contract 

 for Queens and Brooklyn was completed, and on March 19 the 

 contract for an additional million feet, which had been let in 

 December, 1916, was started. This contract was supplementary 

 to the first and enabled me to take care of the conditions caused 

 by the rainy season and the closing down of the water stations. 



As I now look back to what, at the time, seemed likely to be 

 a source of trouble, I am heartily glad that it happened just 

 when it did, for, fortunately, I was then best prepared to meet 

 it. As a consequence, I am now satisfied that conditions can 

 never be worse than they were last spring. Certain areas which 

 were not thought of as needing drainage are now thoroughly 

 taken care of, and no matter what happens, in the way of in- 

 clement weather, a mosquito nuisance will not occur. 



During this year, as last, I steadfastly adhered to my motto 

 ''thorough," and I am a firmi believer that in that word lies the 

 secret of success in mosquito-extermination work. Not how 

 much, but how well, is what I ask my assistants in regard to the 

 work done. I can easily determine whether there has been loaf-
