48 N. J. Mosquito Extermination Association 



Interest in the county was somewhat awakened. Morris is not 

 very strong on the mosquito problem yet. We are trying to educate 

 the people. Our Board of Freeholders are not with us. We tried to 

 get them down here last year, tried to get some of them here this 

 year, but we were not successful. 



With the help of Mr. Chandler, our superintendent, we laid out a 

 campaign for this year which would mean some permanent work, 

 and submitted our plan to Dr. Lipman for the expenditure of about 

 $12,000. The Board of Freeholders made very strenuous objection. 

 They have had some extraordinary expenses during the year 1919. 

 As a result we have only $3,000 again this year to work with. But 

 we hope to carry on our publicity work and possibly do some work 

 in the larger towns. With our work in Morristown, I might add, 

 we had a very rigid inspection of back yards and rain-barrels and 

 found it very effective.

It is always a satisfaction, having laid out a plan, to watch the 

 growth and development of the work. Especially it is true to those 

 charged with a duty to obtain something for the public good. 



During the first years of the Essex County Mosquito Extermina- 

 tion Commission's work, attention was directed primarily to the 

 ditching of the salt meadows and to the control of fresh-water con- 

 ditions near thickly settled communities. From year to year the 

 area of the work was extended and the methods made more effective. 

 Practical experience gained during this period, together with an 

 intimate study of the various species of mosquitoes, their respective 

 breeding places and habits, assisted materially in lessening the 

 emergence of these pests. 



Water being the prerequisite to mosquito breeding, yet existing 

 under so many different conditions, it becam,e necessary to differenti- 

 ate between these conditions in order to fix responsibility for their 

 control. This commission, therefore, arbitrarily divided these water 

 conditions into three classes and established rules to govern each. 



Thus, water being present under conditions created by the laws of 

 nature, such as brooks, swamps, bogs and salt marshes, is definied as 

 being a ''natural condition" and placed in class one, the rule of which
