the valuations of the balance of the state only increased 6.84 times. It 

 is doubtful whether more than ten per cent of the resort possibilities 

 of this area have been developed. 



The writer (12) made a study of tax valuation increase in Cumber- 

 land, Cape May, Atlantic, Ocean, and Monmouth Counties from 1895 

 to 1935 inclusive. The purpose of this study was to see whether there 

 existed any correlation between salt marsh mosquito prevalence and 

 tax valuation increase. In Cumberland there has been no extensive 

 effective mosquito control, in Cape May the work of mosquito control 

 has just well begun, in Atlantic most of the salt marsh has been ditched, 

 in Ocean the ditching of the salt marsh is not as complete as in Atlantic, 

 and in Monmouth such salt marshes as exist are pretty well ditched. 

 Prior to 1915 mosquito control work had not reached the point to 

 affect the taxable values. 



In Cumberland where mosquitoes are present in their old time num- 

 bers county valuation increases have outstripped the shore valuations, 

 while in the other counties, where mosquitoes have been reduced, shore 

 valuations have outstripped county valuations.
