on the bar, and is navigable to New Iberia, 100
miles.

Tennessee River has its sources in the Alle-
ghany Mts., in Tazewell and Wise counties,
Virginia. Its principal head tributaries are the
Holston and the Clinch Rivers, the former of
which receives the French Broad River, and the
latter Powell's River. The Holston and Clinch
unite at Kingston, in Roan co., Tennessee, and
thence the course of the main stream is about S.
W., until it crosses the boundary of Alabama,
near the N. E. corner of the state, and continuing
50 or 60 miles in this direction, bends towards
the N. W., breaking through the Cumberland
Mts., and traversing the entire N. end of Ala-
bama, until, cutting off a small corner of Missis-
sippi, it emerges again into Tennessee, where it
immediately takes a course due N., crossing the
state, and entering Kentucky, across the western
point of which, bearing a little farther to the W.,
it flows on to its confluence with the Ohio, which
is only about 12 miles below the mouth of the

i Cumberland River. The valley of the Tennes-
see divides itself into two great sections, the
upper and the lower. The upper valley is that
which is above the passage of the river through
the Cumberland Mts., and is included between
the two parallel chains of the Appalachian sys-
tem, which form a connection just below this pass.
This upper section is mountainous and much
elevated, embracing an area of about 24,000
square miles. The lower valley of the Tennes-
see is composed of several physical sections, in
N. Alabama, W. Tennessee, and Kentucky, com-
prising in all an area of 17,600 square miles.
Thus the whole valley of this large river embraces
a superficial extent of 41,600 square miles. It
is, therefore, by this standard of estimation, as
well as from its comparative length, which is
near 1200 miles, and from the large volume of
water which it carries, entitled to the first rank
among the tributaries of the Ohio. The difference
in the relative height between the highest and the
lowest extremes of the upper and lower valleys
of the Tennessee is not less than 1700 feet. The
current of every branch of the river is very rapid,
though there are few, if any, direct falls in them,
and they generally admit of boat navigation
nearly to their sources. The whole river has a
mean fall of 2 feet to the mile. It is navigable,
excepting at low water, for steamboats, from its
mouth to Florence, in Alabama, a distance of
259 miles. Here are the Muscle Shoals, where
the river expands to a width of several miles,
and is very shallow. A canal has been made
around these shoals 36 miles long, to admit the
passage of steamboats, and the navigation of the
river above is unobstructed for 250 miles, to the
pass of the Cumberland Mts. The river is here
compressed to a width of 70 feet, besides being
whirled around a projecting cliff, occasioning a
very difficult current for boats, whether ascend-
ing or descending. The river above this point
is only favorable to navigation with the stream.

Tensas River, La., rises in Chicot co., As., flows
