86 AGRICULTURAL EXPERIMENT STATION. 



the direct mosquito supply is concerned. The investigation did 

 not include the thickly settled area of the city itself, nor those lot 

 pools and puddles on the immediate outskirts which can be readily 

 dealt with by the Board of Health. These places furnish the 

 local supply of house mosquitoes and the malaria carriers, which 

 spread out a limited distance into the surroundings. Those 

 clouds that sometimes make life miserable come from the marshes 

 to the west o± the city, and some of them from the Kearney 

 meadows, which are now in' process of reclamation. 



The explorations began in April, 1903, when Mr. H. H. 

 Brehme first went over the meadow, and have been continued 

 from time to time by Mr. E, Brehme and Mr. Grossbeck, who 

 covered the various sections under differing conditions. 



The first area is on the north side of the Plank Road from the 

 Hackensack River east to the highland and north to the old race 

 track. This area has a lot of breeding pools scattered in all its 

 parts ; but there is no difficulty in draining them. Mr. Brehme 

 reports : "We have here the Hackensack River and one good 

 creek running right throug'h the centre of this area from the 

 highland to the river. Besides these two outlet streams there 

 are a number of deep ditches. With all these natural and arti- 

 ficial outlets already present it will be easy work to lay the land 

 dry and destroy the pools in which uncountable numbers of mos- 

 quitoes now breed." 



From this territory every west wind carries mosquitoes into 

 Jersey City and when it is a little south, Hoboken gets its share. 

 On an east wind the flight is in the direction oi Newark, and may 

 add to the supply which the meadows in that city distribute. 



The second section or area is south of the Plank Road from the 

 river and bay to the highland. The meadow here is half a mile 

 wide at its best and extends south about one and one-half miles. 

 Beyond that, south to Bergen Point, all is sound and there are no 

 breeding places. The Morris Canal runs through this piece of 

 meadow land from the Hackensack River through to New York 

 Bay. The little strip lying between the Plank Road and the 

 canal is reported in pretty good condition. 



That part of the meadow lying southwest from the canal is a 

 bad breeding section, but here again, Mr. Brehme reports, we 

 are supplied with outlet streams. The Hackensack is on the west 

 side and there are a number of small natural creeks with a good 

 tide flow, which can be used as outlets for drainage ditches. 



The rest of this meadow was found in good condition to a 

 point south of the Newark and New York Branch of the Central 

 Railroad of New Jersey. Here is another small, but very bad
