permanent relief by closing the ditch or putting a pii>e in its place. 

 It is realized that the place needs watching, and such conditions 

 occur in many places, giving rise to local infestations complained

Orange Mountain Tonrns. 



The towns and villages along the range of the Orange or 

 Watchung mountains are fast increasing in size, wealth and popu- 

 lation, and are in every respect desirable as places of residence. 

 LTnfortunately they suffer at times from the mosquito pest, and 

 South Orange was among the first, if not actually the first, munici- 

 pality in the State to consider the question and to attempt to 

 secure relief by local work. Xo other community has done so 

 much really satisfactoiy work as South Orange has done under 

 the leadership of Mr. Spencer ]\Iiller, and few settlements are so 

 free from local breeding places. The experience gained in that 

 work may well serve as an aid to other bodies, and to some extent 

 the example has been followed in the neighborhood. But in the 

 course of the work it developed that local action, important as it 

 was and effective as it proved, could not be alone relied upon. 

 Mosquitoes came in from other places, and the idea that a hundred 

 feet or even yards was the limit of flight of an adult mosquito was 

 definitely exploded. 



So much a]ipeared in publications of various kinds on the mos- 

 quito subject that a number of other communities along this same 

 ridge have inquired-as to what could be done for their relief. Tliis 

 induced me to provide for a series of collections and inspections 

 extending through the South Mountain Reservation, Maplewood, 

 Springtield. Milllmrn, Short Hills and Summit, to determine ju^it 

 what kind of mosquitoes were offensive and just where they bred. 



Mr. Brelime and ]\[r. Grossbeck were both assigned to the work 

 and separately and together went over the ground from time to 

 time, Mr. Brehme in his task of following the migrations from the 

 salt marshes, Mr. Grossbeck to locate the woodland areas. To 

 determine the species actually troublesome on porches and in gar- 

 dens, 'Mv. Wm. W. Renwick, of Millburn, was good enough to 

 send in examples at intervals throughout the season.
