Chairman BrinkErhoi^f' — I think that Mr. Engle is attend- 

 ing another meeting for a few minutes. We will take Atlantic 

 County, Mr. A. J. Rider, from Hammonton. 



Mr. a. J. RidEr — Five minutes is a very short time to give 

 a symposium of the results of the work in Atlantic County, but 

 I will boil it down to as small a space as possible, so as to bring 

 it within the five minutes. 



Status of Mosquito Control Work in Atlantic County. 



BY MR. A. J. RIDER, MEMBER OE THE ATI.ANTIC COUNTY MOSQUITO 

 EXTERMINATION COMMISSION. 



Mosquito control is a business proposition. To arrive at the 

 status of a business enterprise it is customary to do so on the 

 basis of a percentage of efficiency. The first essential to such 

 a computation is a base or starting point. The only base avail- 

 able in this case would seem to be an assumed perfect control 

 and figure backward. Surely we could not begin at the other 

 end, as mosquitoes appeared in clouds beyond human possibility 

 to enumerate. Now, it is possible to make an approximately 

 accurate count in any specific locality. Notably in the vicinity 

 of completed drainage operations or residential sections where 

 rigid inspection has been maintained. 



I have seen it stated in print — of course it must be true — that 

 mosquito control in Atlantic County was 80 per cent, efficient. 

 I could not say that it was by Brandies, the noted efficiency 

 expert, but it is evidently by some one who had imbibed his 

 theories, and as such is worthy of some consideration and com- 

 parison with views of others. 



Mr. Geist, of the Sea View Golf Club, is quite positive in 

 stating that the reduction in his locality is in relation to 1,000 

 to I. When he was seen to capture the second mosquito he was 

 asked if he would not change his estimate. ''Oh, no," he said, 

 "this is for the second thousand." O'f course, this is computa- 

 tion from the indeterminate end, still it shows a high degree of 

 efficiency.
