ties effected in the time mentioned it is felt that financial assistance 

 along lines previously proposed to the legislature should be extended 

 by the state. 



When the shortage of fuel oil at the beginning of last season 

 threatened to prove a serious handicap to control operations requir- 

 ing that important commodity, the commission sought some suitable 

 substitute but without success. Kerosene was of course available 

 but the greater quantity of that oil required made the cost prohibi- 

 tive. The subsequent decision of the Standard Oil Company to 

 co-operate with the mosquito extermination forces, because of the 

 value of their work as a public benefit, by agreeing to supply all the 

 oil necessary for that purpose, solved a very annoying problem. 

 The Jersey City station of the oil company met the demands of the 

 Hudson County Commission throughout the season without inter- 

 ruption with the same co-operative spirit which has always been 

 extended to the commission by the local manager Mr. S. J. Massey. 



The usual methods of control on the upland were employed prac- 

 tically without change. Breeding places were permanently elimin- 

 ated where possible by draining or filling in, but the use of fuel oil 

 was the principal means of control. 300 cellars in the lower part 

 of Jersey City and Hoboken, constantly flooded with tide water from 

 the Hudson River and forming permanent breeding places which 

 cannot be done away with, continued to give considerable trouble 

 and had to be treated regularly. The 8,000 sewer basins of the 

 County also had to be oiled regularly throughout the pipiens breed- 

 ing period. 



For the purpose of eradicating permanent breeding places of all 

 description which can not be filled in or drained, it is planned to 

 use in 1 92 1 a portable pump with a capacity of 12,000 gallons per 

 hour. This pump will be mounted upon a truck base in which form 

 it can be moved from place to place as required. It is intended 

 mainly for use on the upland but may also be employed for certain 

 emergencies on the marsh. 



With the exception of the towns of Kearny and Arlington, where 

 infestation was rather pronounced quite early, the origin of which 

 could not be definitely traced, mosquitoes did not appear in sufficient 

 numbers to become troublesome until the latter part of July. They 

 continued troublesome in various, sections of the county during the 

 month of August, a condition which prevailed very generally 

 throughout the state, due, no doubt, to the abnormal rainfall at that 

 time, amounting to thirteen days in July and sixteen days, in August.
