The tunnel leading from the well toward the south is 19 inches high, 3 feet 9 inches wide. At 3 feet it branches; one fork, 2 feet high and 17 inches wide, turns eastward and curves to join the east branch from the well. The other branch continues south, but soon closes; in it were found a small piece of an adult's skull and the hip bone of a young child.
The floors in all the branches of the small cave were covered from 3 to 12 inches deep with a reddish mixture of sand and clay, on which were ashes filling the space above almost to the roof. In a few places refuse was found in this silt, of the same general character as that in the ashes, 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 with loose material. The upper 2 feet of this was clean ashes in which were great quantities of refuse, so much that it had all the appearance of a general dumping ground. Below this depth, patches of fine dark earth were mingled with the ashes and refuse. The latter continually decreased in quantity, until at a foot above the bottom they ceased altogether, the lower portion of the deposit consisting of nothing but earth. The pure ashes were slightly damp; and the moisture increased with the depth until at a foot above the bottom the earth was saturated and could no longer be removed with tools.
The refuse in the ashes consisted of animal bones, entire or in fragments; broken flints and pottery; mussel and snail shells; and numerous wrought objects. These continued, though in smaller amount, where the ashes were mingled with earth, though bones and shells were soft owing to the moisture, and could be removed only in fragments. Among them were the flint shown at a in plate 28, and the hematite ax, at a, plate 29. The latter was at the lowest level to which the ashes extended; perhaps its weight caused it to settle below the place at which it originally lay.
Near the middle of this chamber, 2 feet from the rear wall, lying at the bottom of the mixed ashes and earth, were 12 entire and 3 broken leaf-shaped blades; they were not closely piled, or arranged in any order, but seem to have been hastily or carelessly laid or thrown on a small space. Another was found a foot away. They are shown in plate 25.
