ECONOMIC EFFECT OF MOSQUITO REDUCTION 323 



the State of New Jersey in the past, because of the famous or infamous 

 New Jersey mosquitoes. Within recent years I have been personally in 

 contact with several deals running up into the millions where the mos- 

 quitoes, as a condition of environment, made or broke the deal.

"A property on Barnegat Bay was sold for some two million dollars. 

 The closing of this deal was held up very nearly a month until the pur- 

 chasers received full reports as to the possibility of freeing this particu- 

 lar section from mosquitoes, and I feel confident that if the mosquito 

 control work in that county had not been in the advanced stage which 

 it was, these capitalists could not have been induced to purchase this 

 tract." 



In the last twenty-five years there have been three instances where 

 malaria has been practically eliminated from sections where 100 or 

 more cases were experienced in a single year. The first was in Franklin, 

 Sussex County, where David Jenkins (16) has shown how this elimina- 

 tion of malaria was accomplished by eliminating the breeding of Anoph- 

 eles quadrimaculatus. The second occurred in Mercer County near 

 Princeton (6). The third case is recent and occurred in Camden 

 County, where there were 110 cases of malaria the first year and two 

 cases of malaria the second year. This experience leaves no doubt in our 

 minds that malaria can be readily eliminated by the control of the 

 Anopheles mosquito which serves as a vector for this disease, but the 

 control of such things as fowlpox of chicken, encephalomyelitis of 

 horses and heart worm of dogs by elimination of the mosquito carrying 

 the infection has not yet been worked out.
