EXPEEIMENT STATION REPORT. 627 



August Sth, the Rumson E'eck area was looked over and the 

 marsh was found in good condition. On the upland some C. pipiens 

 were breeding, but they were not numerous at this time. The 

 Port-au-Peck property had been sold since it was drained and tents 

 w^ere now found on it to shelter camping parties. A year ago it was 

 iilmost impossible to get on the meadow at all without gum boots, 

 and no camping party would ha,ve maintained itself twenty-four 

 hours, if, indeed, it peTsisted long enough to pitch its tents pTop- 

 erly. It was learned that some hundred houses had been planned 

 for at this point, increasing property values many hundred per 

 ■cent., all because the marsh mosquitoes had been eliminated. 



At North Long Branch, which has a small salt marsh area which 

 is not yet drained, some C. soUicitans were found August 9th, and 

 there Avere also some C. pipiens that were town bred. At Long 

 Branch proper only the local C. pipiens was found. 



September 1st and 3d the final inspection of the marsh areas 

 was made and no breeding was found. The drainage scheme works 

 perfectly, and so far as could be discovered not a single marsh 

 mosquito developed, where untold millions emerged in years gone 

 by. The entire area is kept in order by one man with a motor boat 

 who gets from one point to another, patrols the ditches to see that 

 there is no interference and removes any obstructions that may be 

 brought in by tides or the wash from waves caused by steamers or 

 otherwise. 



Whatever mosquitoes were found in this region were bred in 

 neglected gutters, lot pools, cesspools and other stagnant water 

 areas. After attention had been called to it matters improved, and 

 on September 1st the clogged gi^itters were found opened, many 

 pools had been filled or graded and other places had been oiled. It 

 will not do even for communities that have destroyed the marsh 

 species to neglect the conditions that favor the development of 

 2)ipiens in a season like that of 1906. 



STATEN ISLAND. 



The work done on Staten Island has been kept under constant 

 observation because of its bearing upon the effectiveness of the 

 work to be done in New Jersey. The Arthur Kill, which separates 

 the island from the New Jersey mainland, is so narrow that it
