142 ECONOMICAL MINERALOGY. 



In Ulster County, a sulphur spring occurs near the base of the Shawangunk mountains, 

 about a mile west of Springtown in the town of New-Paltz. Gas rises, at intervals of a few 

 seconds, from the bottom of this spring, and the water is supposed to possess valuable medi- 

 cinal properties. 



In Greene County, there is a sulphur spring rising from the slate of the Catskill mountain 

 series, about three quarters of a mile west of Greenville, and within a few miles of the Hud- 

 son ; another, two miles west of the village of Catskill ; and still another, issuing from the clay 

 beds about four miles west of Athens, in a valley at the base of the water lime group of the 

 Helderberg limestone series.* 



In Albany County, there is a sulphur spring at Coeymans Landing ; one in Guilderland ; 

 one in Rensselaerville, in the valley of Fox's creek, three miles from Preston Hollow ; one 

 in Wendell's Hollow, near the city of Albany ; and one in the town of Watervliet, &c. 



In Rensselaer County, we have the old Harrowgate Springs near the village of Green- 

 bush ; one near the north end of the city of Troy, besides others of less importance. 



In Saratoga County, numerous springs of this kind are found. 



The springs just enumerated are usually impregnated with the sulphuretted hydrogen in 

 sufficient quantity to change the colour of the solution of acetate of lead ; but, in some in- 

 stances, the quantity is so small as to be perceptible only by its odour. The waters generally 

 yield, upon evaporation, sulphate and carbonate of lime. 



Northern New-York. Some interesting sulphur springs occur in the northern parts of 

 the State. Thus in the town of Beekman in the County of Clinton, is a spring of this kind, 

 which has acquired some celebrity. The water is said to contain sulphur, iron and carbonic 

 acid. 



In St. Lawrence County, there are several sulphur springs. Of these, probably the 

 most important is that which occurs about a mile from Massena, on the banks of the Racket 

 river. The water of this spring is strongly charged with sulphuretted hydrogen. According 

 to Dr. Emmons, the solid matter which it holds in solution is chloride of calcium or magne- 

 sium, or both. There are other springs of a similar kind on the banks of the same stream, 

 which are more or less resorted to by the inhabitants of this and of the adjacent counties. 



Sulphur springs are often met with in the County of Lewis ; but none of them, I believe, 

 are of much importance. 



Western New- York. In the western part of the State, and especially in the district 

 adjoining the Erie canal, sulphur springs are of still more frequent occurrence than elsewhere, 

 and at the same time are also more interesting in their nature. It is further worthy of re- 

 mark, that in general, the strata of rocks through which they rise are entirely different from 

 those with which they are associated on the Hudson river. 



Schoharie County. Near the village of Leesville, in the town of Sharon, is a spring 

 largely impregnated with sulphuretted hydrogen, which has acquired a high reputation for the
