hich,
from the appearance of the ends, were broken, twisted, or bruised off
with blunt tools like stone hatchets. Most of those remaining are
lying on massive loose rocks now forming the floor, though the ends of
some are seen projecting from beneath stones much larger than two men
can lift. It is possible the latter have recently slid or slipped from
higher up the slopes, but the indications are that they have dropped
from the roof since the time of these early explorers. If this be the
case, it points to a considerable antiquity for the remains, because
no such downfalls are known to have occurred since the cave was first
explored by white men.

So much work has been done about the entrance of late years for
improving the approaches that excavation would be useless, even if
allowed, unless carried to a depth of more than 20 feet. Such work
would greatly interfere with the plans of the management.

WHITE'S CAVE.--This is about three-fourths of a mile from Mammoth
Cave. The entrance, quite small, is near the crest of a ridge, and the
floor descends abruptly. Only a narrow chamber exists within reach of
daylight, and the cave is wet all the time a short distance back.

COLOSSAL CAVE.--It is said to be 4 miles from Mammoth Cave, but is
really only a little more than 2 miles. The present entrance is
entirely artificial, the descent to the floor being about 120 feet.
The original entrance was in a crevice which explorers descended by
means of ropes. It is said that another entrance is known to one man
who, however, has to crawl a long distance.

SALT CAVE.--This is 4 miles from Mammoth Cave, though belonging to the
same company. The entrance is at the bottom of a conical sink hole
draining about an acre. Not much water runs into the cave from this
cause, as the surface slopes outward from the margin except on one
side, where a ridge leads to the hills. A spring which comes out near
the top of the sink falls over a ledge at the bottom into the
entrance to the cave. It is said that this water soaks into the ground
within a few rods and that just beyond are large, dry rooms, well
adapted for habitation, which formerly contained many evidences of
aboriginal occupation. Exploration is impossible now, as the entrance
was effectually closed some years ago by throwing in logs, brush,
rocks, and earth, in order to protect the formations from relic
hunters. The water from the spring falls directly on and flows into
this, and can
