fefled the cave, which i f it is not low water, you muft do in a
M i vou 'come to the firft ranges o f pillars, which are ftill not
H i ha lf as large as thofe a little beyond. Over-againft this place
■ fmall iiland, called in E r fe , Boo-Jha-la or more properly B uacba-
I or the herdfman, feparated from the main, b y a channel not
m 3 fathoms wide ; this whole ifland is compofed o f pillars with-
¿«t any ftratum above them ; they are ftill fmall, bu t b y much the
k a t e f t formed o f any about the place.
“ T h e firft divifion o f the ifland, for at : high water: it is divided
intn two, makes a kind o f a cone, the pillars converging
iUether towards the centre : on the other, they - are in. general-
laid down flat, and in the front next to the main, you fee how
Beautifully they are packed together ; their ends coming out
ignare with the bank which, they form : alL thefe have their tranf-
verie feftions exa ft, and their furfaces fmooth, which is b y no
means the- cafe with the large ones, which are cracked in all di-
reftions. I much queftion however, i f a n y one o f this whole
land o f Buachaille is two feet in diameter.
“ T h e ’ main ifland oppofed to Boo-jha-ld and farther towards
tie N. W . is fupported b y ranges o f pillars pretty ereft, and .
ito’ not ta ll, (as they are- not uncovered to the bafé) o f large diameters,
and at their feet is an irregular pavement, made b y the
upper fides o f fuch as have been broken-off, which extends as fa r
under water as the eye can reach. Here the forms o f . the pillars
different from thefe. Thofe I faw were ereft, and ran along the face of a high cliff,
fcnt ft rangely in their middle, as if unable, at their original formation, while-
hufoftftate, to fupport themafs of incumbent earth that preffedon them.
