Circular 111 



annual tax income from the Essex County meadows is more than 

 three times as large as the annual sum expended by the Essex 

 County Commission in its effort to give protection from all 

 species of mosquitoes to the half million people living within its 

 borders. 



Table i gives the total ratables (net valuation taxable) for 

 Essex County for each year, with the annual per cent of increase,

Table 2 ^ives the total ratables of the Newark Meadows, 

 with the yearly percentage of increase and the tax produced for 

 each year from 1896 to 1919, inclusive. 



Figure 2 illustrates more graphically than the tables the re- 

 markable agreement between the rise in meadow valuations and 

 the progress of salt-marsh mosquito-control work. 



The striking coincidence between the progress of mosquito- 

 control work on the Essex salt marsh and the increase in 

 meadow ratables may be illustrated in still another way. The 

 increase in valuation for Essex County from 1905 to 1918 is 166 

 per cent ; the increase in the ratables of the Newark meadows 

 for the same period is 1913 per cent, or more than n times the 

 per cent of increase of the county.
