of Edinburgh, Session 1878 - 79 . 
To the south of Easdale, there is an extensive terrace along the 
coast, about 18 or 20 feet above high-water mark, and some hundreds 
of yards wide, bounded by a range of high rocky cliffs, with caves 
which evidently had been formerly reached and undermined by sea 
waves. On this terrace lay a cluster of boulders, several of them 
of grey-coloured granite, which most probably had been lodged 
where they now lie by ice floating from the north, and arrested in 
its further progress south by these rocky cliffs. Several boulders 
were noticed by the Convener at and near the tops of these cliffs, 
which he regretted not having had time to inspect. 
Mr Clerk informed him that on the hill immediately to the east 
of Easdale, about 1200 feet in height, there were near the top 
several large boulders, which he hoped would be examined at some 
future period. 
Whilst it seemed probable that these Easdale grey granite 
boulders came from the north, there was one large claystone boulder, 
of a purple colour, which, from its position, seemed to the Convener 
to have come from the south. Its size was 12x7 x 6 feet. It lay 
on the shore near Clachan Bridge. On asking Mr Clerk if he knew 
of any rock in situ similar to that of the boulder, he pointed to a 
hill about a mile distant, situated to the south. 
The Convener has referred to several boulders of a purple-coloured 
claystone, very similar to this one, as having been seen by him at 
“ Lailt ” (3) above, and “ Duntonichan ” (4) above, which also 
suggested transport from the hills to the south. 
(8.) The Convener on 1st July ascended Ben Cruachan from 
Inverawe, up as far as 2725 feet, and made the following observa- 
tions : — 
Until a level above the sea was reached of about 1330 feet, 
few boulders were met with. At and above that height 
the boulders were numerous, and many of them of large size. They 
were most numerous on the N.W. shoulder of the hill. In that 
direction there was the least obstruction to transport. Due N., 
E.E., E., S.E., S.W., due W., there were hills of formidable 
height which would obstruct. Towards the W.N.W. and N.W, 
there were only the hills in Mull and Ardnamurchan, distant from 
30 to 40 miles.
