what modified by accidental circumstances, as in the places where 

 there was much drip or where burrowing animals had greatly 

 disturbed the earth. Under the deposit containing the Pleistocene 

 remains was a gTaveUy material mainly made up of fragments from 

 local rocks and a few small quartz pebbles, but no animal remains 

 occurred in it. The flint scraper already referred to was discovered 

 in this chamber in our trial examination last year, and we had 

 hoped that a more thorough search and the removal of all the 

 deposits from it to the local drift at the bottom would have yielded 

 some additional implements, but uiifortunately nothing further to 

 show human occupation was discovered in this chamber, unless it is 

 indicated by the few doubtfully calcined bones and antlers found in 

 it. A narrow tunnel which turns sharply to the right from this 

 chamber was cleared out to a distance of about 16 feet, its further 

 exploration being postponed until next year. The deposits in this 

 tunnel were like those in other parts of the cavern, but they were 

 much more moist, on account of a rather free drip, and the divisions 

 in the deposits were consequently less marked. The bones, however, 

 occurred here at about the same horizon as in other parts, but they 

 were not at all plentiful. Fig. 11 (sect. 2) shows the thickness of 

 the deposits near the commencement of this tunnel.

The main tunnel was cleared out, with the exception of the deepest 

 deposit, to a distance of over 150 feet from the entrance, and figs.
