date of soda or common salt—more than 1-4 carbo-
nate of lime, and the remainder consists of carbonate
of soda, carbonate of magnesia, and carbonate of iron.
But what more particularly distinguishes and charac-
terizes die water of this spring, is the fact that it con-
tains, the moment it is dipped, nearly 1-2 more
than its bulk of carbonic acid gas, a quantity hitherto
unprecedented in any natural waters, except those
of this county.
" The Columbian is an, acidulous chalybeate ;
it contains 354 grains of solid contents to the gallon,
nearly 2-3 of which is muriate of soda, about 1-3 car-
bonate of lime, 7 1-2 grains of carbonate of icon, and
a small proportion of the carbonate of soda and mag-
nesia. It contains something more than its bulk of
carbonic acid gas.
" The Flat Rock is likewise an acidulous cha-
lybeate. It contains the same quantity of iron as
the Columbian, but a less proportion of the saline
ingredients, while it contains rather more of the gas-
eous property.
"The Hamilton,* High RoCk and Presi-
dent, are saline, their solid contents being compos-
ed of muriate of soda, in the proportion of from 1-2
to 2-3, and carbonate of lime in the proportion of
about 1-3. They likewise contain iron, carbonate
of soda, and magnesia, in considerable quantities,
and more than their bulk of gas.
" At Ballston Spa, the mineral waters all be-
long to the acidulous chalybeate class. The Old
Spring contains 253 grains of solid contents to a
* Since the publication of Dôct. Steel's Geologic-
al Report, the Hamilton spring has been sunk by its
proprietor, Doct Clarke, several feet deeper than
formerly ; the result of which is, that a far superior
quality of water is produced, falling little, if any,
short of the far-famed Congress.
