mination Commission, the work of treating the marshes in such a 

 fashion as to eliminate the breeding of this pest has gone steadily 

 forward. No one can escape the fact that this large upward trend 

 of the taxable values of the Essex County salt marshes has been 

 coincident with the progress of the work against the salt-marsh 

 mosquito. In view of the testimony from factory owners and oper-

 Increase in Taxable Values in Essex County 



ators in this district, and in view of this coincidence of mosquito- 

 control work and large increases in taxable values, it is hard to escape 

 the conclusion that mosquito control has played a considerable part 

 in this increase in land values. 



While the Newark meadows have been selected for illustration be- 

 cause the permanent mosquito eradication work is more nearly com- 

 plete there than elsewhere in the metropolitan district, the same 

 relatively enormous increases in ratables is found on other meadows 

 where the control work has advanced far enough to be considered a 

 factor in real-estate values.
