o explain this fact otherwise than by the
assumption that the bed of the river has been elevated in recent
times, although there are no other indications apparent that such is
the case.

SHEFFIELDS.--In the river bluff 2 miles above the Sheffield end of the
railway bridge is a crevice or joint which has been widened to 10 feet
at the outlet by water percolating from the top of the bluff. When
discovered, a rock wall was piled across it near the entrance. Behind
this human bones were found with "pieces of pottery and other things."
They were close to the surface. Subsequent explorations have revealed
nothing below them. It is plainly a burial cave for Indians. The river
now reaches at flood tide to within 10 feet of the floor. The earth
covering the bones may have washed over them, as there is some
evidence farther back in the crevice that surface material is still
carried in from the rear, in very small amounts, during rainy seasons.

ROCK SHELTERS.--Several very large rock houses exist on the southern
slope of the hill or "mountain" lying a mile to 2 miles south of
Pride, 7 miles west of Tuscumbia. Water drips from the roofs, keeping
the floors wet all the year and collecting in pools to which stock
resorts when the little creeks or brooks in the ravines become dry.

It is useless to search in this part of Alabama for caves presenting
indications that they may have been habitable, or the reverse, in ages
past. The native rock is a cherty or flinty limestone, crumbling
easily, and readily susceptible to changes from atmospheric
influences, and especially so to the action of water. New subterranean
channels are continually developing, with consequent changes in the
interior of any cavern near them.

ISBOLL CAVES.--It was reported that habitable caves with spacious
rooms occur on the Isboll farms, near Limrock. They have entrances
and front chambers of ample size to move about in, though not more
than 15 feet wide. There are broader expansions back some distance
beyond daylight. In both caves rocks up to 15 or 20 tons in weight
strew the floor, until only narrow passageways exist between them. In
addition, water flows from them in rainy seasons, being frequently 2
feet or more in depth.

BLOWING CAVE.--This takes its name from an outward current of cold air
which is so strong as to distinctly modify the temperature of the
atmosphere at least 100 yards from the entrance. The opening and the
front
