of upright Pillars. Above thefe Pillars lies another 
Stratum of black Stone 20 Feet high ; and above 
this is again another Stratum of upright Pillars riling 
in fonie Places to the Top of the Cliffs, in others not 
fo high, and in others again above it, where they arc 
called the Chimneys. 
This Face of the Cliffs reaches for two computed 
Miles Haft from the Caufeway, that is about 3 mea- 
fured Englijh Miles, to the Houfe of Mr. John 
Stewart two Miles Weft of Sahntoy . The upper 
Pillars feem to end over the Caufeway, and, if I 
miftake not, become fhorter and fhorter as one goes 
from it, lying between two Binds of Stone like 
Seams of Coal, and like thofe little Pillars found 
in c Derb)'jhire §. 
Thefe Binds probably meet together all round, and 
inciofe this extraordinary Work of Nature; andiffo, 
the Pillars muft be very ftiort towards the Extremities. 
I was led to this Conje&ure by the following 
Obfcrvations : The lower Stratum of Pillars is thal 
which goes by a Defcent into the Sea, and which 
makes what is called the Giants Caufeway j and 
where this Delcent approaches the Sea, it leems pro- 
bable that the Pillars become fhorter and fhorter, fo 
as to end nor much further off. Now the upper 
Bind of this Stratum may have been of fo foft a 
Nature, as by degrees, in Procefs of Time, to have 
been wafhed away by the Sea. And 111 the Cliff 
over the Caufeway 1 law fcveral Pillars lying along 
in a rude manner almoft horizontally, which feemed 
to me to be fome.of the Pillars of the upper Stra- 
tum fallen down by the giving way of the Bind
