CENTRAL LAKES — TOMPKINS COUNTY. 



Station, Ithaca — At the College of Civil Engineering, Cor- 

 nell University. 



Established 1874; latitude, 42 deg. 27 mln. north; longitude, 76 deg. 29 mln. west; eleva- 

 tion, 810 feet. 



This station is situatedi on the hill bordering the eastern side of 

 Cayuga Lake valley, its distance from the head of the lake being 

 about 1 mile and its elevation above the lake level 400 feet. South 

 of the city of Ithaca, which lies immediately below the station, the 

 valley divides into two branches, the first and main branch extend- 

 ing through the hills toward the southwest, while the second forms 

 the narrow channel of Six Mile creek, which flows from the high- 

 lands southeast of the city into Cayuga lake. The meteorological 

 station has an open exposure toward the main valley on the west, 

 while eastward, after a slight rise near the station, the surface is 

 nearly flat along the course of the Fall creek; but numerous hills 

 arise to heights varying from 300 to 500 feet above the general 

 level, at distance® of a mile or more to the southeast of the station. 

 The instrumental equipment of the station is as follows: 

 Barometers. — These instruments are placed in the basement 

 clock room of the engineering college.
