It may not be out of place to mentiotni here that the Nassau- 

 Suffolk County Mosquito Extermination Association is working 

 up public sentiment in Suffolk County, which is just east of 

 Nassau on Long Island, in favor of organizing a commission for 

 that county, and a bill will soon be introduced in Albany to 

 organize such a commission. 



MOSQUITO PROBI.EMS 01^ NASSAU COUNTY. 



The following account of the problems we have to face, as 

 outlined by Mr. Buttrick may be of interest: 



Nassau County extends from the eastern boundary of Greater 

 New York, on Long Island, for a distance of some 25 miles 

 eastward in a broad strip clear across the island from north 

 to south — also a distance of some 25 miles. It has an area 

 of some 274 square miles, and a population of about 100,000, 

 and 250,000 to 300,000 during the summer and fall seasons. 

 The population is largely suburban, and much of the land is 

 held in large estates, particularly along the north shore. There 

 are no large cities in the county. 



Near the north shore range of hills the remains of the old 

 terminal moraine of the glacier which formed Long Island, 

 gives the topography a rolling nature, with elevations up to 

 nearly 400 feet and averaging 1501 feet more or less. South 

 of this country is a flat, sandy outwash plain, sloping gradu- 

 ally southward, and giving way to a vast stretch of salt marsh 

 fringed on the ocean side by a barrier beach of sand dunes. 



From an engineering point of view there are reahy four main 

 mosquito problems in the county, two for each shore, determined 

 in every case by the physical character of the different portions 

 of the county. Naming these problems in order of their im- 

 portance they are : 



(1) South Shore Salt-Marsh Problem. 



(2) North Shore Fresh- Water Problem. 



(3) North Shore Salt-Marsh Problem. 



(4) South Shore Fresh-Water Problem.
