area begins just back from the series of sand hills fring-ing the 

 shore, continues along the highland at Schellinger's Landing 

 and beyond toward the Two-mile Beach. The marsh i^ now 

 being filled in by the Cape May Realty Company and its days as 

 a mosquito breeder are numbered. To the east, south and west 

 the influx of mosquitoes is prohibited by the sea and bay; from 

 the north nothing can come from points beyond the Cape May 

 limits. Onl}^ from the northeast at Two-Mile Beach can any 

 migration come and northeast winds mild enough to favor mos- 

 quito flights are rare in summer. In a single year at a very mod- 

 erate cost, Cape May can be made mosquito proof. Since the 

 following reports were written, the railroad companies have 

 improved the conditions along the trolley line, but the municipali- 

 ties at present writing have done nothing, though all the facts 

 have been submitted to them. 



Practical Results of Mr. Vicreck's Investigation at Cape May. 



Cape May, Cape May Point, South, West and Bast Cape May 

 receive their largest supply of mosquitoes from local breeding 

 places. During the day sotticitans was always dominant ; in the 

 evenings Anopheles crucians and Culex salinarius or pungens or 

 both were the chief nuisances. In the favorite day retreats, viz., 

 the salt hay, mosquitoes were scarce when the wind was from the 

 south, with the grass moist; more numerous when the wind 

 came from the north, causing the grass to become dry, and most 

 numerous during calm weather, particularly after a brood had 

 emerged, if no strong winds intervened. 



The observations at Cape May were begun May 26th and 

 concluded September 30th ; in the beginning solUcitans alone 

 was numerous, but after June 26th Anopheles crucians and Culex 

 salinarius came in great numbers, Culex tceniorhynchus and 

 syhestris next in importance; C. perturbans appeared periodi- 

 cally in small numbers. 



The features that have to do with the problem are best taken 

 consecutively from Cape May Point to Sewell's Point. Starting 

 on the bay shore, for some distance up is highland down to the 

 bay ; at Town Bank very high. The suspicious area is the marsh 

 drained by Pond Creek and of considerable extent. The natural 

 drainage of Pond Creek marsh has never been permanently inter- 

 fered with, so the marsh has a chance to drain and fill with the 

 falling and rising of the tide. For a short distance on the north 

 and south sides of the marsh the edge thereof was explored ; on 

 the north side all suspicious spots were full of salt water and
