bed farther up, a condition which could not be remedied.

Bedrock was reached at a depth of 3 feet below the channel. The lower
2 feet of this distance was through a black, mucky substance which was
so tough and sticky that removing it was like digging through a bog.

Following the bedrock as a floor, the western side of the deposit was
first examined. It had a width of 35 feet at the mouth of the cave,
gradually narrowing inward for a distance of 75 feet, where it
terminated at the level of the water. Its greatest elevation, at the
side of the entrance, was about 10 feet; but this does not mean that
its thickness was so much at any point, as the rock sloped upward
quite as rapidly as the surface. So many stones were scattered through
it, fallen from the sides and roof, or rolled in from the outside
where they had broken loose from the cliff, that not more than
one-fourth of the area could be excavated. These rocks varied in size
from cobblestones to blocks weighing 3 or 4 tons. They were at all
levels, some lying on the rock floor, others only slightly imbedded in
the earth. Yet the superficial accumulation extended under all of them
except such as were in direct contact with the bedrock, proving that
the cave was occupied throughout the period in which such downfalls
occurred. An additional evidence of age is the fact that the usual
debris, such as bones, flints, pottery, ashes, etc., lay in immediate
contact with the bedrock where this has weathered to a chalky
consistency from 2 to 4 inches in depth since these objects were left
there.

Owing to the uneven surface of both the bedrock and the deposits on
it, the thickness of the latter varied from 1 to 3 feet--not including
the muck, which last, however, disappeared at the level where the rock
rose above the water line. But, whatever the depth, more than half the
overlying material was pure ashes; either resting undisturbed on the
fire beds, or piled in irregular masses, where they had been thrown to
get them out of the way. The largest ash bed was near the wall; it
measured from 4 to 7 feet across, with a very uneven outline, as if
many fires had been made there at different times.

The objects discovered included flint knives, spearheads, arrowheads
(mostly broken), with many spalls and chips; potsherds (only very
small pieces were found); animal bones; mussel shells; bone
perforators; chert nodules, more or less flaked; two stone beads or
buttons; a small frag
