ing. gimning and otlier shore sports. The raih-oad service to 

 both beaches is excellent and they are nearest in a straight line 

 to Philadephia. Island Beach is also in direct connection by rail 

 along the coast to New York City. 



There are two flourishing points, Seaside Park, on Island 

 Beach, and Beach Haven, on Long Beach, where an attempt has 

 been made to improve conditions and with a fair measure of suc- 

 cess. It is a common belief on these beaches that the mosquito 

 supply comes from the mainland, but that is a mistake, for there 

 are local breeding places in abundance, capable of supplying the 

 entire strip. There is no doubt that under favorable conditions 

 some mosquito flights from the edge of the highland will reach 

 the beach — the evidence, indeed, is positive on that point, but 

 such occurrences are the exception rather than the rule, and were 

 these shore flights the only source of trovible, there would be lit- 

 tle cause for complaint. 



Along the main shore are a number of towns of considerable 

 size and importance — Barnegat, Manahawken and Toms River, 

 among others — and all of these suffer much from the mosquito 

 pest. 



I have covered a good portion of both of these beaches myself 

 and have spent some days at Seaside Park and at Beach Haven 

 exploring the surroundings in each direction. At Beach Haven 

 considerable work was done and that is separately reported upon. 



Messrs. Wagner and Mellor together or singly covered almost 

 the entire territory with the view of determining what could be 

 done to mitigate or remove conditions. Mr. Grossbeck covered 

 the territory from Barnegat City to the Junction, and found the 

 entire marsh area dry, but with numerous depressions recently 

 filled with water, which had given out enormous swarms of mos- 

 quitoes. He confined his work to the marsh and did not get 

 into the sand hills at all. Later he went over a section of the 

 mainland, using Manahawken as a base, to determine the im- 

 portance of the cedar swamps from the mosquito standpoint. 

 Mr. Brehme covered the same section of the mainland, but ex- 

 tended his work much further south. He also explored some of 

 the islands between Beach Haven and the mainland, as well as a 

 section of Long Beach. Mr. Viereck covered part of the sec- 

 tion between Bay Head and the end of Island Beach, so that, 

 practically, I have had the wdiole stretch of Barnegat Bay, main- 

 land and shore, under observation for two full seasons. The con- 

 culsion is that there is nothing especially difficult in ridding the 

 entire shore line of the mosquito pest, provided the whole work 

 can be done at one time. This strip of beach is somewhat pecul-
