Harrowgate spring, in Greenbush; one near the north end of the city of 
Troy; and otheis in various places near the springs of Ballston and Sa- 
ratoga. 
The sulphuretted waters found in the region just designated, are usu- 
ally impregnated with the gas in sufficient quantity to change the colour 
of solution of acetate of lead; but in some instances the quantity is so 
small as to be only perceptible by its odour. The gas is probably the 
result of the decomposition of the sulphuret of iron, which is always 
disseminated through this slate rock. And as carbonate of lime is also 
found, though in small quantities, in the same formation, we can very 
well account for the existence of sulphate of lime being so general in 
these waters. 
Sulphur Spring in Clinton county. — Some interesting sulphuretted 
springs occur in the northern counties of the State. Thus in the town 
of Beekman, in the county of Clinton, is a spring of this kind becom- 
ing somewhat noted, where a commodious house for the accommodation 
of visiters has been erected. The wa-ter of this spring is said to con- 
tain sulphur, iron and carbonic acid, but I have not yet had an oppor- 
tunity of examining it. 
Sulphur Springs of St, Lawrence county. — St. Lawrence county, that 
great depository of mineral wealth, has long been celebrated for the 
sulphuretted springs which it contains. Of these, probably the most 
important is that situated about a mile from Massena, on the banks of 
the Racket river. The water of this spring is strongly charged with 
sulphuretted hydrogen, and also holds in solution carbonates of soda, 
lime and magnesia. Several other springs of a similar kind are to be 
found on the banks of the same stream, and they are more or less re- 
sorted to by the inhabitants of this and the adjacent counties. 
Sulphuretted springs frequently occur in the county of Lewis, but 
none of them, I believe, have acquired much celebrity. 
Sulphur Springs of Western JYew-York. — It is in the district adjacent 
to the Erie Canal that these waters are more frequent, as well as more 
interesting in their nature, than they are in any other part of the State. 
And it is a striking fact, that they rise here through strata of rocks en- 
tirely different from those with which they are associated on the Hud- 
son river. In what may be called the canal district, the rocks are usu- 
ally limestone, or contain large admixtures of carbonate of lime, while 
gypsum, or the sulphate of lime, is also found in great abundance in
