es, but in very small amount. This is not significant; such
remains were dragged down by animals, which range everywhere. The two
deposits are quite separated and distinct.

The clay and sand on the rock bottom came from disintegrated rock on
top of the ground outside, or at any rate from some level higher than
that where they are found now; but how ashes, shells, broken bone, and
especially how worked objects came to be in places too contracted for
a man to creep, and where they could be neither carried nor pushed, is
not to be explained except on the hypothesis of a chamber above,
whence they may have worked or may have been thrown down; but at no
place, either in the cave or in the outside surface, could there be
found any evidence of such communication.

Fifty-five feet from the mouth of the cave, in the east wall, is a
crevice into whose lower portion extended the red clay of the cavern
floor. It branched into various tortuous divisions, all of which were
filled with ashes containing a large proportion of refuse. It appeared
at first that all this had settled in, or been thrown in, from the
main cavern; but one branch, having a very irregular outline, was in
such situation and trended upward at such an angle that it could not
have been filled from below. As in similar cases previously noted,
however, no other opening to it was to be found. The smallest workman
cleared it out to as great a distance as he could crawl and use a
trowel, but did not succeed in reaching the end of the deposits.

At the bottom of the crevice were ground-hog burrows extending between
loose rocks, under ledges, and into the red clay. All these were
followed as far as they could be, and found to contain quantities of
refuse. There was also a considerable amount of fine dark earth in the
burrows, showing they have another outlet somewhere. Occasionally a
mass thrown out by a shovel or a trowel contained more refuse than
ashes. There was nearly everything which was found elsewhere in the
cave, and almost every shovelful contained something worth preserving.

Near the rear of the cave erosion of the lower part of the eastern
wall formed a rudely triangular recess or cavity 30 feet long by 7
feet deep at the widest part. The upper margin of this was below the
surface of the ashes, so that its existence was not suspected until
these had been removed from in front of it. The roof was 5 feet above
the rock bottom, the entire space being filled w
