Fulton County, in which all of my collecting was done, 

 contains about all of the varied situations in which the different 

 crane-flics occur. The Adirondack Mountains, with their scores 

 of little lakes, occupy the northern half of the county ; a river 

 flows through the northeast corner; while great tracts of 

 marshland (the VJei) lie in the eastern part. The altitude 

 ranges from about 500 feet up to 2,700 feet. My main col- 

 lecting grounds are as follows: 



1. The Woodworth's Lake and Canada Lake country, in 

 the central, or west central, portion of the county. Small 

 mountain lakes, lying between 1,500 and 1,600 feet above sea 

 level. The character of the fauna and flora is typically Cana- 

 dian. Most of the species of Tipulidae secured by Ostcn 

 Sacken at Trenton Falls, and by Needham at Old Forge, occur 

 here. 



2. The Sacandaga Park country, in the extreme northeast 

 of the county, is on the Sacandaga River, a branch of the 

 Hudson. Sport Island, in the river, is about half a mile in 

 length, and several hundred feet in width. The ground is 

 mostly low, with grassy fields in the center, the margins of 

 the island being overgrown with rank shrubbery, ferns, etc., 

 forming choice haunts for many insects. The island is con- 

 nected with the mainland (Sacandaga Park) at the northwest 

 end, by a large wooden bridge. There is a broad strip of low 

 land bordering the northeast coast of the island for several 

 hundred feet. On each side of the island is a dam of about six- 

 feet drop, skirting the east shore of the island from the dam 

 %v several hundred feet to the south, are broad, pebbly beaches. 

 On the southeast side of the island is a deep indentation into 

 the land, an offshoot of the main stream, but filled with quiet 

 water ; this is called the "bayou." The altitude of the island is 

 about 875 feet. The fauna and flora shows an intermingling 

 of Canadian and Transition forms. 



3. Gloversville, N. Y., in south-central part of the county : 

 altitude, 900 feet. 



4. Johnstown, N. Y., in southern part of the county: alti- 

 tude, 700 feet.
