you come to Corvorant’s Cave, where
ihe bed beneath the pillars is railed,
and the pillars themielves decreafe
in height: they are, however, tolerably
diftind, till you are paft a bay
that extends very far into the country,
and on the fide o f it the pillars
entirely difappear. The mountains
here coniift of a dark brown ftone, o f
which I cannot affirm with certainty
whether it is lava or not, and where
not the leaft regularity is to be ob-
ierved ; but as foon as you pais
the foLith-eaft fide o f the ifland, the
flpnes begin again to aíTume a regular
figure, though fo gradually, that
it is fcarcely perceptible at firfl, till
at lail, the regular and crooked pillars
again appear witli which I began my
defcription.
The pillars have from three to ieven,
ijclcs, but the greater number have five
or iix,^ and ib crouded together, that
a heptagonal pillar is fiUTounded with
ievcn others, that join elofely to its
ieven fides. In Ibme places, however,
there are little infignificant fif-
ÍIIres, but they are filled up with qt/arz ;
but
but in one place they had even made
way through a number o f pillars,
though without in the leail deftroying
their regularity. The pillars confiil
of many joints or pieces, o f about a
foot in height, which fo exadly fit
upon one another, that it is difficult to
introduce a knife between the inter-
ftices. The upper piece was gene-
I'ally concave, fometimes flat, and
rarely convex ; i f the upper joint was
flat, the loweil was fo likewife ; but
when it was excavated, the lower one
was rounded and reverfed.
The fides of the pillars are not all
equally broad. The following meafurements
were taken o f four pillars:
