this valuable article. Missouri, Kentucky,
and Tennessee have their share. Immense quantities are found in the
mountains along the Kenhawa, in Western Virginia, and it is now employed
in the manufacture of salt. The Cumberland mountains in Tennessee
contain immense deposits.

_Muriate of Soda_ or common salt, exists in most of the states and
territories of this Valley. Near the sources of the Arkansas
incrustations are formed by evaporation during the dry season, in the
depressed portions of the immense prairies of that region. The
celebrated salt rock is on the red fork of the Canadian, a branch of the
Arkansas river. Jefferson lake has its water strongly impregnated with
salt, and is of a bright red color. Beds of rock salt are in the
mountains of this region. Several counties of Missouri have abundant
salt springs. Considerable quantities of salt are manufactured in
Jackson, Gallatin and Vermillion counties, Illinois. Saline springs, and
"licks" as they are called, abound through Kentucky, Tennessee, Indiana,
Ohio, Western Pennsylvania, and Western Virginia. Salt is manufactured
in great abundance at the Kenhawa salines, 16 miles above Charlestown,
Va., and brought down the Kenhawa river and carried to all the Western
States. Much salt is made also on the Kiskiminitas, a branch of the
Alleghany river, at the Yellow creek above Steubenville, and in the
Scioto country in Ohio. The water is frequently obtained by boring
through rock of different strata, several hundred feet deep.

Copper, antimony, manganese, and several other minerals are found in
different parts of the West, but are not yet worked. _Nitrate of potash_
is found in great abundance in the caverns of Kentucky and Tennessee,
also in Missouri, from which large quantities of Saltpetre are
manufactured. _Sulphate of Magnesia_ is found in Kentucky, Indiana, and
perhaps other states. Sulphur and other mineral springs are very common
in the western states.

_Vegetable Productions._--_Trees, &c._ Almost every species of timber
and shrub common to the Atlantic states is found in some part of the
Western Valley. The cotton wood and sycamore are found along all the
rivers below the 41 deg. of N. latitude. The cypress begins near the
mouth of the Ohio and spreads through the alluvion portions of the Lower
Valley. The magnolia, with its large, beautiful flower, grows in
Louisiana, and the long leaf pine flourishes in the uplands of the same
region. The sugar maple
