152 ECONOJIICAL MINERALOGY. 



gen gas is continually evolved from them. According to Prof. Charles U. Shepard, the water 

 of the Seneca spring is strongly sulphureous, but is free from uncombined carbonic acid, and 

 'contains notable quantities of the carbonates of lime, magnesia and soda, together with the 

 sulphate of lime.* 



Southwestern Countie.s. We have accounts of numerous sulphur springs in the south- 

 western range of counties. 



In Chenango Countv, there are several sulphur springs in the town of Pitcher. At some 

 of these, houses were erected for the accomnlodation of- visiters, but they are now seldom 

 resorted to. 



In Broome Countv, the Nanticoke Sulphur Spring was formerly in considerable repute. 

 Similar springs also occur at Bellona in this county. 



Sulphur springs are said to exist in Cortland County. 



In Tompkins County, there is a spring of this kind in the .town of Dryden,' ten miles east 

 of Ithaca, which has acquired some celebrity ; and another on Six-mile creek, a mile or two 

 southeast of the same village.! 



In Tioga County, in the town of the same name, is a sulphur spring ; and a similar one 

 occurs in the southwest corner of Barton, on the east bank of Chemung river.| 

 ■ In Steuben County, Campbelltown, a village in the northwestern part of the town of 

 Campbell, has a spring of this kind near it, which is said to be .remarkably pure, and to emit 

 a stream of air which may be inflamed when confined ; and similar springs occur in the towns 

 of Jasper and Urbana, in the same county. 



Sulphur springs are occasionally found in the County of Cattaraugus. One upon the 

 land of Judge Leavenworth, near Randolph, is pretty strongly charged. Several have been 

 noticed issuing from the Cashaxjua shales, at the base of the cliffs upon the Cattaraugus creek, 

 and the south branch. 



Chautauque County. Sulphur springs are here of frequent occurrence, and apparently 

 have some connexion widi the issues of carburettcd hydrogen gas, for which this county has 

 become so celebrated. In the village of Fredonia, many springs of this kind have been dis- 

 covered ; but they are said to lose their sulphureous character in a short time. This, how- 

 ever, is not the case with those found elsewhere. On the shore of Lake Erie, about a mile 

 east of Van Burcn Harbour, a spring, highly charged with sulphuretted hydrogen, issues out 

 of the slate rock, nearly on a level with the lake. The water is cold and clear, but the quan- 

 tity is not veiy abimdant. The specific gravity is 1 .00193 at 60° F. ; and it contains minute 

 portions of the carbonate of lime, sulphate of lime and sulphate of soda. 



Another spring, of a similar kind, occurs, near the sandstone quarries at Laona, a mile south 

 of Fredonia ; and others are also found in the town of Sheridan, a mile and a half from Lake 

 Erie.
