8 N. J. Mosquito Extermination Association 



During this whole period, from 1901 to 1907, the State Experi- 

 ment Station expended about $15,875, and municipahties several 

 thousand more. As the result of these efforts, the best methods of 

 control were worked out and a considerable amount of salt-marsh 

 trenching was installed. 



In 1906 the Experiment Station was directed by Chapter 134 of 

 the Laws of 1906, to undertake the drainage of the salt marsh and 

 an appropriation of $350,000 was authorized. Under the terms 

 of this act, the work has gone slowly forward. The largest appro- 

 priation in any one year was $30,000 in 191 3, and the smallest $4,8oO' 

 in 1916. By June 30, 1920, the station will have expended under the 

 provisions of this act a total of $238,300. 



If $15,875 spent by the station previous to 1906, under authority 

 of Chapter 98, Laws of 1902, and Chapter 80, Laws of 1905, is 

 added to the above $238,300, we find that the State will have 

 expended altogether on mosquito work by June 30, 1920, $254,175. 



In 191 2 the county mosquito extermination commissions were 

 authorized by Chapter 104, Laws of 1912. At the present time there 

 are 11 of these commissions actively engaged in mosquito-control 

 work in Hudson, Bergen, Essex, Union, Middlesex, Monmouth, 

 Ocean, Atlantic, Cape May, Passaic and Morris. These counties 

 comprise 47 per cent of the state's area, 76 per cent of its popula- 

 tion and 82 per cent of the total ratables. 



From 191 2 to 191 9, the county commissions expended on mosquito 

 work a total of $1,240,907. During this period, the state spent 

 approximately $99,800 for the same purpose. 



In the fiscal year ending October 31, 191 9, the commissions spent 

 a total of $243,382.71 on control work. The state appropriation 

 for 1918-19 was $10,000; the state appropriation for 1919-20 is 

 $15,000.
