Chairman Brinki:rhoi^i^ — It has been suggested that some- 

 body might have something to say along the line of discussion 

 of Dr. Darnall's paper. If there are any who would like to 

 discuss it we will limit them to five minutes, and the Chair is 

 now willing to listen to anyone who might want to discuss the 

 paper of Dr. Darnall. 



If there is no discussion on this paper I will transfer the chair 

 to the presiding officer. 



PrESidknt Darnai.1, — The first paper on the program, "The 

 Circulation of Water on the Drained Salt Marshes — the Need 

 for It and the Way to Obtain It," by Jam-es E. Brooks, of Glen 

 Ridge. 



The Circulation of Water on the Drained Salt Marshes — The 

 Need for and the Way to Obtain it.

I hope the expert mosquito fighters here this afternoon will 

 pardon my mentioning facts long known to them. There may 

 be someone present to whom the story of mosquito warfare is 

 new. 



The fight against moscjuitoes is war. A war of extermination 

 against an enemy with a record of thousands of years of tri- 

 umphant victories over the human race.^ The reason for our 

 many defeats has been due to the crude method of warfare prac- 

 ticed by the human race. Until very recently every man, woman 

 and child was his or her own moscjuito exterminator — using the 

 ''swat the fly" method on the back of the neck, ankle, face or 

 other exposed bit of human anatomy. 



There was always a great mysetry about that wonderful de- 

 fense against mosquitoes — the screen. You invariably found 

 that you and the mosquitoes were on the same side of the screen. 

 Against such primitive defences the mosquitoes have used aero- 

 planes, submarines, inoculation, and mass attacks for thousands 

 of years, and their victories were far from ''bloodless."
