the lurfaccy Is about thirty yards, and eight or nine 
yards broad. 
For the firft twenty yards I was let down (which 
was at the South fide), I could alTift myfelf with my 
hands and feet, as it was a kind of confined dope j 
but after that, the rock jetted out into large irregular 
pieces, on all the three fides next me ; and on that ac- 
count I met with fome difficulty in pafiing, for about 
the fpace of ten yards more j at which depth the rope 
was moved at leaft five or fix yards from the perpen- 
dicular, Thence down, the breadth was about three 
yards, and the length at lead: five or fix, through 
craggy irregular flits in the rock, which was rather 
dirty, and covered with a kind of mofs, and pretty 
wet, until I came within about twelve or fourteen 
yards of the bottom, and then the rock opened on 
the Eaft fide, and I fwung, till I defeended to the 
floor of the cave, where I perceived there was light

any print. When I was at the bottom, I perceived 
that the cavern confifted of two parts ; the firfi; (into 
which I defeended, at the place I began to fwing) 
being a cave, in fliape not much unlike to that of an

firft dome, to almofl: the bottom of the fecond cave,, 
or dome, with fuch an angle, that the further end 
©f the cave is lower by twenty-five yards, than the- 
place where I firft landed.
