Prockedings of Fifth Annual Meeting 99 



Mr. Winship — One man covered from one to three square 

 miles a day during this last year. 



President Brinkerhoff — Any further remarks? 



Mr. Chari.es B. Chave (New York) — I would like to ask 

 Mr. Winship to give us an idea of how much he figures per acre 

 on the average ought to be put in. 



Mr. Winship — It has been my experience, Mr. Chairman and 

 gentlemen, that from two hundred to six hundred feet per acre 

 should be installed. It will vary according to physical condi- 

 tions. 



Secretary HeadeEE — Mr. Chairman, I think it might be well 

 to explain our experience in New Jersey on the number of feet 

 per acre. The system adopted in Greater New York for drain- 

 age of salt marsh, as I understand it, is an arrangement that may 

 be designated as a checker-board system. That is, the ditches 

 run two ways, cutting the marsh up into relatively small blocks. 

 The owners of the marsh would not permit the adoption of such 

 a system. We figure that about three hundred lineal feet per 

 acre on an average is what is necessary to drain an open salt 

 marsh. We understand the advantages of the checkerboard 

 system, that with its many outlets it is less easily blocked, but we 

 feel that conditions in our state will not permit us to adopt it, 

 and we feel that we have met the situation by a more careful and 

 continuous patrol. 



President Brinkerhoff — Any further remarks? If not, we 

 will proceed to the next paper, ''Progress in Mosquito Control in 

 Connecticut," by Dr. W. E. Britton, State Entomologist of Con- 

 necticut, New Haven, Connecticut. Dr. Headlee will read this 

 paper. 



Secretary Headlee — I received this morning a letter from 

 Dr. Britton as follows, dated January 31 : 



I very much regret that the illness of Mrs. Britton prevents me from at- 

 tending the meeting. Mr. Walden is also so tied up that he cannot come. 

 With regrets, I am, 



Very truly yours, 



(Signed) W. E. Britton, 



State Bntomologist,
