large part of the roof. In descending from the general level of 
the terrace, down the slope of the hollow and down the rocky 
steps, so as to be well within the roof of the first chamber, one 
has come down 23 ft. ; from this point, down the talus and into 
the second chamber is a further descent of about 22 ft. Thus the 
floor of the second chamber is about 45 ft. from the ground above, 
and the roof being 37ft. high, it follows that only 8ft. of grass, 
earth and rock form the roof of this chamber. At the further end 
of the second chamber is a passage upwards, down which a small 
stream runs and loses itself at the entrance into the chamber. 
The passage ascends 18 ft. in a distance of 72 ft., and is tolerably 
broad and high. It then soon becomes very narrow and difficult 
to pass, and contains water in parts which was nearly 3 ft. deep till 
we lowered its level by cutting away the rocks at the entrance to 
this gorge. From the last point to the end of the gorge is a 
length of about 100 ft., and altogether there has been a very 
slight rise. At this point the third and last chamber begins. It 
is about 160 ft. long and slopes very gently downwards as far as 
the beginning of the last 30 ft, where the descent becomes rapid 
and leads down to a small pool about 3 ft. deep. At the further 
end of this pool the walls of the cave unite, .presenting at their 
junction step-like irregularities. The total length of this division 
of the cave is 463 ft. 6in., and in this length are three chambers, 
and two passages ; a very short one from the first to the second 
chamber, a very long one from the second to the third. 
The first chamber has been thoroughly worked in its upper 
layers at any rate, in the former explorations, about 22 and 16 
years ago, by Mr. Jackson of Settle, Mr. Farrer and Mr. Denny. 
The original state of the floor is now entirely obscured by the 
debris of former workings. In a drawing published in the " Pro- 
ceedings " of this Society, illustrating Mr. Denny's paper, this 
chamber is shown to have a layer of charcoal 2ft. thick on the 
floor, in which, as well as in the first chamber of the W. side, most 
of the celebrated remains were found. The second chamber was
