ich is made from sea-water, concentrated by repeated
evaporations, and at length crystallized.

What is Spring Salt?

That salt which is not made from sea-water, but from the water of salt
wells or springs; large quantities of this salt are made in the United
States, in some parts of which saline springs are numerous.

In what manner is it obtained?

The means employed for extracting the salt from the water vary
according to circumstances. In hot countries, the water is merely
exposed to the action of the sun, until the water is evaporated; the
salt procured in this manner is considered the best.

What method is usually employed in countries where the sun's heat is
not sufficiently powerful?

In climates where the rays of the sun do not afford sufficient heat,
the water, which has been partly evaporated in large shallow
reservoirs formed in the earth, called salt-pans, is poured into
enormous coppers and boiled for four or five hours: when the contents
of the copper are wasted to half the quantity, the liquid begins to be
crystallized; the vessel is again filled up, and the brine again
boiled and purified: this is repeated three or four times. After the
last purifying the fire is kept very low for twelve or fourteen hours,
and when the moisture is nearly evaporated the salt is removed, and,
after the remaining brine has drained off, is placed in the
store-houses.

In what countries is Salt generally found?

This substance, so necessary to the comfort of mankind, is widely
distributed over the face of the earth, and nothing, except, perhaps,
the air we breathe, is more easily placed within our reach. The ocean
is an exhaustless store-house of this valuable article. Those nations
of the earth which are placed at a distance from the sea, find
themselves provided with magazines of salt, either in solid masses, or
dissolved in the waters of inland lakes, or issuing from the solid
rocks in springs of brine. At Salina, Syracuse, and other places in
Onondaga Co., New York, salt springs are remarkably abundant, and
yield annually several millions of bushels; immense quantities are
also obtained from the salt-wells on the Great and Little Kanawha, and
other places in Western Virginia; it is also extensively manufactured
in the western part of Pennsylvania, and throughout the Western
States.
