both iides, and in the moil Interior
part, fupport an arched vault, compofed
o f the obtufe points o f pillars
crouded clofe together. The bottom
o f the cave, which is filled with clear
frefli water feveral feet in depth, is
likewife covered with innumerable
pieces o f pillars, that compofe its
floor. The dolour o f the pillars is
o f a blackifli grey ; but between the
joints there is a yellow ftalaflitic
cruil that makes thefe diviiions more
diilindl, and produces an agreeable
effed to the eye, by the many different
contrails o f colour. It is fo
light within the cave, that one can
diilinguifli the innermoil range o f
pillars perfedly well from without.
The air in it is very pure and good,
as it is conftantly changed by the
rifing and falling of the water during
the tide. Very far into the cave there
is a hole in the rock, fomewhat lower
than the fnrface o f the water ftanding
in it, that makes a pleaiing kind o f
noife oil every flux and reflux of the
tides. One may walk in moft parts o f the
