the road in a low hill, within two miles of Coleraine ; 
fo that the whole extends for about eleven Irifh miles, 
or fourteen Englifn. 
Beyond Coleraine, to the eaft of Magilligan, I faw 
in the rocks towards the fea-cliffs, the Hones in the 
rocks towards the fea-cliffs, the Hones in the hills 
very regular, appea: ing at a diHance much like thefe 
pillars. This is fix computed miles beyond Coleraine, 
and confequently about ten Engliih miles from the 
laft pillars. 
At Fairhcad alfo, a high point of land, three miles 
to the eaH of BallycaHle, towards the top of it, the 
rock appears as in grand pillars. They fay it is not 
in joints, but it has fomething of the appearance of 
a grand Gothic piece of workmanfhip. 
As I fpent a week at the Caufeway, and fent away 
by fea to Dublin as great a variety of the Hones as I 
could conveniently get, particularly a large odtagon,. 
with the eight large Hones round it; a pair of lefs,, 
with eight pair, that encompafs it; two fmall penta- 
gon pillars, about fourteen inches over, one of them 
three f eet ten inches and a half high, the other five 
feet feven inches ; one hexagon pillar, about the 
fame Hze, and five feet five inches high ; all which 
I have placed in my garden ; fo I have had an op- 
portunity of confidering it at leifure. 
It is a black Hone, weighty and brittle : and I have 
been informed, that it was tried in a glafs-houfe, and 
that it melted with kelp, fo as to make the black 
glafs bottles : which experiment, I have been told, 
was made by Mr. Dobbs of this kingdom, who is now 
in London.
