Sec. This measure also represents the thinnest portion of the wall
separating the main cave from the outer cave.

The walls were, as is usual in caverns, somewhat irregular, there
being a narrow bench or shelf along each side near the front, while
projections and indentations alternated from front to rear. There were
numerous small holes and crevices, enlargements of seams and joints by
percolating water at an early stage in the cave's history. These
furnish homes for various wild animals, and nearly all of them contain
bones, sticks, and trash taken in by ground hogs and wood rats which
seem to find much pleasure in carrying such things from place to
place.

The work of excavation began at the extreme front of the cave, where
the original bottom, a mixture of sand, clay, and chert gravel, had
been exposed through removal of the ashes by winds and driving rain.
Almost immediately rocks, large and small, fallen from walls and roof,
were encountered and interfered greatly with the digging. In the upper
foot of the clay were streaks of sand and ashes, among which a mussel
shell and a flint chip were found; and the top of the clay was quite
uneven, appearing as if carried and thrown here, as perhaps some of it
was early in the occupancy of the cave, with the object of making a
more even or level floor farther back. But this admixture was only
superficial; below it, the material had all the appearance of a
running water deposit.

A ledge extended along the east wall for 40 feet, with a width of 12
to 14 feet; at the inner end it was about 4 feet below the general
level of the floor. At 8 feet below its top a second ledge projecte
