230 REPORT ON THE DENEHOLE EXPLORATION With some difficulty we cleared the greater part of the floor of the chamber nearest to No. 3, and then found its height to be about 14 ft. 6 in. The accumulation of material in this shaft-closed pit obliged us to tunnel from a recess towards the end of one of the lateral chambers to the corresponding chamber on the other side of the shaft in order to get access to the whole of the pit. The tunnel being completed, we found that the three chambers of No. 7 most remote from No. 3 differed from those first entered in having no side-recesses towards their ends. We also discovered that the partition between Nos. 7 and 8 had been broken, and that we could get through into the three nearest chambers of the latter pit. The hole in the partition was nearly circular in form, and about 6 ft. in diameter, and, were the floor cleared of debris, would be seen to have its base some 7 or 8 ft. above it. The adjacent chambers on both sides were carefully rounded off, and the break had the appearance of being entirely the result of accident, and contrary to the wishes of the original makers. We were again obliged to tunnel in order to get into the chambers on the other side of the shaft of No. 8. We then discovered that the existence of a similar but smaller hole in the partition between Nos. 8 and 12 gave us admission to the latter. In this case the rounding off and apparent completion of the adjacent chambers of the two pits previous to the break in the partition were even more strongly marked than in the preceding one. On both sides we had the some- what steep slope usually seen at the ends of denehole chambers— slopes up which fallen dogs or badgers would instinctively climb—as their claw-marks in such positions abundantly testify. Indeed it seems quite possible that holes such as those between Nos. 7 and 8, and Nos. 8 and 12 may have owed their origin, though not their present development, to the frantic exertions of imprisoned animals. Another break in the partition between Nos. 12 and 13 admitted us to a single chamber of the latter, the only one at present open to us, this pit appearing to be too much choked up by debris to be worth any attempt at further exploration. But we obtained admission to the whole of No. 12 by means of a tunnel connecting the two chambers nearest to No. 8, and found it to be entirely exceptional in plan. In No. 2 we have a pit of the same nature as the ordinary six-chambered pits, but with only five chambers actually excavated, the sixth being represented only by a slight recess. But in No. 12 the two primary chambers, that leading to No. 13 and the
