We presently passed beyond the bone-bed, and found that the passage bifurcated (Fig. 83, C and D), the smaller branch going straight forwards and gently upwards (Fig. 90), while the larger stretched at right angles from it and passed gently downwards. In the former there was a second bone-bed similar in every respect to that already described, which continued undiminished in thickness until it rested directly on the floor. It afforded a square area of about fifteen feet. The passage was about sixteen inches high and three feet wide, and gradually narrowed until at a distance of twelve feet from the bifurcation a stalactite six inches long reached the floor and formed a vertical bar, as if to forbid another ingress. When this had been explored as far as we could crawl, the larger branch (Fig. 83, D, and Fig. 91) engaged our attention, and we soon discovered a third layer of bones of the same character as the others, and in the same position, excepting that in some places it was in immediate contact with the roof. In width it was six, in length fourteen, and in square area eighty-four feet. From its further end to the termination of the passage there was not the slightest vestige of bones or teeth, and a stiff grey clay rested on a horizontal layer of sand on the floor. Here the passage suddenly turned upwards until it became so small and barren that it was not worth our while to pursue it farther. It doubtless rises to the surface, like the large fissure opposite the entrance of the cave shown in Fig. 88.[196] The exploration was resumed the following year by Mr. Ayshford Sanford and myself, and yielded vast quantities of fossil remains. We cleared out the space marked 1863 in the plan, and discovered a flint implement at the point marked _d_, in Fig. 83. My friend the late Mr. Wickham Flower has also worked the cave, more particularly at the right-hand side of the entrance chamber.
