PENNSYLVANIA MINERAL SPRINGS. 135 



A few hundred yards north of this spring there is a 

 group called the 



"HEMLOCK SPRINGS." 



These springs emerge from slate strata, and contain some 

 iron, with carbonate of lime. They have a temperature of 

 45 Fahr., and are situated in a dense forest of hemlock- 

 trees. 



" CAKATION SPRING" 



Is five or six hundred yards east of "Hemlock Springs." It 

 is higher up in the geological series, emerging from slate, 

 and sandstone interlayers, does not contain appreciable 

 quantities of any earthy salts, being a water of exceeding 

 purity. 



West of Rhododendron Spring, perhaps one hundred 

 rods, is QUEMAHONING SPRING, the water containing, ac- 

 cording to Booth, Garrett, and Camac, a trace of sulphate 

 of lime and magnesia. It is nearly a pure water, emerging 

 from a group of slate rocks and sandstones. 



"MEADOW SPRING" 



Is still farther west than Quemahoning, and possesses the 

 same general character, according to the tests of the labo- 

 ratory. 



" DISCORD SPRING" 



Emerges from a mass of slate and shale, containing traces 

 of salts of lime, and iron. 



"BRANDY SPRING." 



This spring derives its name from the generous flow of that 

 beverage which occurred at the time of its discovery. It is a 

 pure freestone water at the temperatute of 45 Fahr., and, 

 according to Booth, Garrett, and Camac, contains only 

 the smallest appreciable traces of lime and magnesia. It is 

 a few hundred yards south of the Mountain House, supply- 

 ing that house and its baths with water, and, according to
