Near the surface, 18 feet from the entrance, 14 feet from the east wall, were the right half of a skull and of a lower jaw; a few small, scattered pieces of skull were found near them. The teeth were much worn, some of them were decayed, and two had the roots swollen and distorted by ulceration. South of the skull were fragments of feet and leg bones, probably belonging with it. This interment was of much later date than the others.
Thirty-two feet from the front, 16 feet from the east wall, 2½ feet below the surface, and a foot above the bottom of the talus, was a folded skeleton, on left side, head toward the interior of the cave, face directly upward. So much of the skull as could be recovered is shown in plate 17, a, b. The teeth were much worn, the bones broken, soft and spongy, falling away with the clay as it was removed from about them. The femur was about 17½ inches long.

Wear of teeth among aboriginal people does not of necessity denote a great age for the individual. Grit from ashes and fine sand from mortars and pestles will cut away the enamel to a much greater extent than would result from the use of ordinary food.
The condition of the teeth mentioned, as well as of some from other localities, is shown in plates 18 and 19.
From the inner end of the ditch, or runway, at the entrance the excavation was carried back for 40 feet in a direct line; or making allowance for passing around a massive rock which was in a position where it could not be blasted, for 43 feet; the depth of the talus here was 3 feet.
On the east side the talus was removed to the wall, a distance of 28 feet from the edge of the trench, and the wall rock exposed for 22 feet, to the rear bank of the excavation.
All work, so far, had been carried on at a level a few inches below the bottom of the talus, which rested directly upon the floor of clay washed out from the interior of the cave.
Beginning next at the outer end of the trench, the entire space included in the first excavation was deepened by a little more than 6 feet, giving a new floor about 13 feet lower than the highest part of the talus. All the material thus removed showed that it was laid down by flowing water, sometimes so quiet as to deposit clay of impalpable fineness, sometimes with a velocity sufficient to carry stones weighing 3 or 4 pounds. The material varied--red clay, now jointed, was the topmost layer; below it, in patches and layers, were dark earth, resembling soil; clay of different shades of yellow, brown, red, and gray, sometimes almost blue; some of it uniform, some of it mingled, one or any or all of the different sorts in small compass; deposits of one sort filling sharply defined channels or potholes cut in some other sort; occasionally there was a slight admixture of sand. All included limestone pebbles, which were plentiful in some deposits but entirely absent from others, were weathered to a chalky consistency, the larger ones to a depth of perhaps half an inch, the smaller ones throughout. Scarcely any chert was included, although it is abundant on the hill; the few pieces seen were very small.
