located in the counties of Burlington, Ocean, Atlantic, and Cape 

 May. It was estimated that 11,438,400 lineal feet of 10-inch by 

 30-inch ditch, or its equivalent, would be required. On a short 

 time basis (150 to 200 days) it would involve the expenditure 

 of $257,364 for actual contract work, and an overhead charge of 

 $5,897.90. On a long time basis the estimate was $228,768 for 

 actual contract work and the overhead charge $5,897.90. The 

 work comprehended in this plan would give to the plant at Elm- 

 wood as nearly complete freedom from the mosquitoes as an opera- 

 tion of this kind could possibly do. This also meant that salt marsh 

 mosquitoes at Mays Landing would occur very infrequently and 

 then only in small numbers. 



Plan No. 3 contemplated the completion of all salt marsh areas 

 within a radius of 30 miles of these plants and situated in the 

 counties of Burlington, Ocean, Atlantic, Cape May and Cumber- 

 land, and involved the cutting of 35,111,360 lineal feet of 10-inch 

 by 30-inch ditch, or its equivalent, costing on a two-year basis, 

 $790,005.60 with an overhead charge of $18,104.29. The tre- 

 mendous area involved made a shorter time limit for com- 

 pletion impossible. The freedom given the Elwood plant by 

 this plan would probably be no greater than that obtained 

 by carrying out plan No. 2, but the freedom at Mays Landing 

 plant would, under this plan, be about the same as that obtained 

 at the Elwood plant under plan No. 2. 



The estimates of time were based on the known performance of 

 special salt marsh ditching machinery. A single machine of this 

 type, run on piece work, could average 5,000 feet per day. There 

 were at least ten of these machines on the salt miarshes of New 

 Jersey and New York. 



As to the maintenance of ditching installed, it was explained that 

 there existed in the State of New Jersey two types of legal or- 

 ganization working for the control and elimination of the salt 

 marsh mosquitoes. The first was the State Experiment Station, 

 operating under an act passed in 1906, and the second the County 

 Mosquito Extermination Commissions, operating under an act passed 

 in the year 1912. The first organization was the authorized agency 

 for the expenditure of State funds, and the second the authorized 

 agency for the expenditure of County funds. The work of one 

 county commission was correlated with that of other county
