the species, and the entrance into the city from the south of the 

 Elizabeth brood was interestingly traced. Furthermore, the fact that 

 Staten Island was a factor in the New Jersey problem was conclusively 

 demonstrated by some investigations made by Mr. Brehme. Collections 

 sent in from the Elizabeth marshes early in the season showed only 

 Culex ccmiator, and that was also the record from the Linden and 

 Railway meadows. But on Staten Island Culex sollicitans was found 

 to be the dominant species, and it seems certain that practically all the 

 sollicitans found in early June in the Newark district of New Jersey 

 were migrants from Staten Island. At the same time it was deter- 

 mined that the mosquitoes bred on the Linden and Rahway marshes 

 followed up the valley of the Rahway and crossed the mountain range 

 at the gap near Milburn; Morristown, Madison and the surrounding 

 country being supplied with their mosquito troubles in great part from 

 Linden and Rahway. 



The Oranges and the immediately surrounding territory receive 

 specimens from Elizabeth and Staten Island; quite a number of 

 sollicitans coming from South Orange at a time when there were none 

 bred in New Jersey so far as I or my agents could find. 



Elizabeth, the first of all the municipalities to do satisfactory marsh 

 work, a])propriated $2,000 for the further drainage of the marsh lands 

 within its border and received $500 of the State funds in addition. 

 This sum was devoted to ditching work east of the Central Railroad 

 of New Jersey, between Bound Creek and Elizabethport, under the 

 direction of Mr. Louis J. Richards, liealth officer of the city, who 

 used the True ditching machine to good advantage. Mr. Brehme 

 made a preliminary survey of the marshes, locating the danger spots, 

 and during the summer he made frequent, and I occasional, visits to 

 the marshes. The conditions on these marshes are complicated by the 

 dam carrying the New Jersey Central Railroad, which cuts the natural 

 drainage and backs up the surface water without outlet, turning a 

 once sound, clean meadow into a quagmire and a veritable mosquito 

 mill. 



Negotiations are in progress which will, it is hoped, result in a 

 contribution of work or money from the railroad company to aid in 

 restoring a satisfactory drainage scheme and in improving those 

 natural outlets which the railroad work impaired. It is also expected 

 that the city will make a further a]ipropriation which, with what may 

 be contributed from the State fund, will suffice to clean the Elizabeth
