Hudson County

This report of mosquito-reduction work done in Hudson County 

 during the season 1919 is very brief, and advisedly so, because first, 

 the time allowed for the submission of these reports is limited ; and 

 second, to go into the matter in detail, as is done in our annual re- 

 ports to the Experiment Station and to the Board of Chosen Free- 

 holders of the County and made public record, as provided for in 

 Chapter 104 of the Laws of 191 2, would seem to constitute an over- 

 lapping of endeavors, useless repetition and waste of your valuable 

 time. 



The problems encountered at the beginning of the season were, of 

 course, not materially different from those of previous years, and the 

 methods employed were practically the same as used in the past, i. e., 

 the making of new ditches, cleaning and repairing of ditches pre- 

 viously made on the meadows wherever found necessary for the re- 

 moval of sewage and stagnant water ; installing permanent improve- 

 ments such as pump, sluice-gate, etc., for the purpose of making 

 more effective the drainage system previously made ; the securing of 

 improvements by railroad companies, manufacturers and property 

 owners generally on their property wherever necessary and possible ; 

 the filling in or applying of oil on both meadow and upland where 

 such could not be drained; oiling sewer catch-basins (about 8,000 

 in number in the county) ; the elimination of minor breeding places, 

 wherever found, by such means as appeared most feasible. Vigilance 

 and thorough inspection throughout the county were maintained dur- 

 ing the breeding season. 



Contracts were let at the beginning of the season for all the ditch- 

 ing work planned and 145,488 feet of new ditches were made, mostly 

 on the stump-lots, the cost ranging from 3 cents per lineal foot in. 

 the clear grass meadows to 12 cents in the stump-lots. During the 

 season 22,335 ^^^t of ditches previously made were cleaned, repaired 

 and widened by contract, costing from 3 to 12 cents per lineal foot, 

 depending upon the location and the nature of the work to be done.
