voted to the elimination of the disease-bearing species, the ex- 

 penditure has been amply justified, no matter what it was. They 

 have eliminated yellow fever and malaria, and the cost was 

 undoubtedly small compared with beneficial results. 



Just a word in regard to Mr. Gie's figures in Honolulu. I 

 visited Honolulu last summer, and talked with the President of 

 the Territorial Board of Health. I do not know the cost of the 

 initial campaign of a number of years ago, but since that time 

 the work has been entirely under the Board of Health, and the 

 charges have been reduced year after year until at the present 

 time they are very small ; and during my stay in Honolulu I did 

 not see a single mosquito, although I was hunting them. The 

 salt-marsh mosquito is not the problem there, and they have no 

 malarial mosquitoes. The yellow fever mosquito and the other 

 rain-water^barrel mosquitoes are the ones which concern them. 



Mr. Gies — Just a word more. I think Dr. Howard has stated 

 that most of the mosquitoes were yellow-fever mosquitoes and 

 domestic mosquitoes breeding in the. neighborhood of houses, and 

 that they do not have to fight salt-marsh mosquitoes or malarial 

 mosquitoes, and all the rest of the mosquitoes found in our com- 

 munities. Now, it is a comparatively simple matter to do* yard 

 inspection work, and the cost for eliminating simply the breeding 

 places around houses is very much less per capita than where 

 you are carrying on a general campaign. That will, to some 

 extent, explain why where in. tropical countries they are doing 

 work against- not only the yellow-fever mosquitoes, but malarial 

 mosquitoes, the figures are very much higher than they would be 

 in Honolulu, for instance. 



The President — The Program Committee have prepared a 

 symposium on "Recent Advances in Mosquito Control Work," 

 and it gives me pleasure to introduce our worthy First Vice- 

 President, Dr. William Edgar Darnall, of Atlantic County. 



Dr. Darnaix — Mr. President, ladies and gentlemen: Our 

 problem in South Jersey resolves itself into two varieties of 

 mosquitoes. As you probably know, Atlantic County and South 

 Jersey is not troubled with the various kinds of mosquitoes that
