extensive research, the earth must be wheeled or otherwise removed to
the sink hole in front, and the whole floor brought to a nearly
uniform level.

So far as appearances go, this cavern is better adapted for occupancy
than any other which has been examined. The depth of earth shows it to
have been open for a long period. If nothing can be found here,
denoting extreme antiquity of man, it would seem useless to make
further search in central or western Kentucky.

BEAR CREEK.--A very large rock house is on the right bank of Bear
Creek, 3 miles above its mouth. It would afford good shelter to a
large number of people, except in rainy seasons when they were most in
need of it. After heavy storms the creek covers the entire floor.

Other rock-shelters exist along Green River above and below Bear
Creek. They are not worth investigating. Some are flooded; others
difficult of access; still others become muddy after rains; while in
none of them is there any great depth of earth.

WARREN COUNTY

CRUMP'S CAVE.--A mile north of Smith's Grove is a large sink hole,
from one side of which extends a cave nearly a mile long. There is
abundant room and a good light near the front, and it is reported that
quantities of ashes were formerly to be seen on the earth a short
distance in. A considerable outside area drains into the cave, and the
floor at the present time is everywhere so wet as to be quite muddy.
Much water also falls from the roof. A hydraulic ram, not far from the
entrance, formerly forced water from one of these falls to the farm
residence. A descent of 6 feet, over large rocks and wet earth, brings
one to the nearly level floor, 40 feet from the mouth. The amount of
flood water running into the cave is indicated by a gully 4 feet deep
and the same in width, while trash and driftwood litter the floor from
wall to wall for more than a hundred yards.

THOMAS CAVE.--This is a mile north of Bowling Green. The roof of a
cavern has fallen in and forms a high mound of rocky debris, down
which a path winds on each side, giving access toward either end of
the cavern. There is scarcely a possibility that it was ever occupied.

MILL CAVE.--Three miles south of Bowling Green a stream emerges from
the foot of a slope, flows a hundred yards through a canyon-like open
channel, and disappears under a cliff. This is another instance of an
open cave due to a falling roof. The open end is large and forms an
excellent shelter for c
