says {Land. Geol, Society's Proceedings^ voL xviii. p. 296) — “ I was 
not a little surprised to find that the ice had come from the S.W., 
up Glen Eoy. ..... The strata had been so blunted and 
rubbed on their S, W. exposures as to show plainly that the move- 
ment came from that quarter; and high up on the brow of the 
adjoining hill I saw several very large blocks and boulders that 
appeared to have been shifted or moved some distance ..... by 
glacial action.” 
Mr Jamieson suggests that this rubbing of the rocks, on their 
S.W. exposures, was due to “glacial action.” If ice moved up the 
glen it could not have been glacier, but floating ice. 
(2) In Glen Gluoy Valley^ adjoining Glen Roy, and opening like 
it towards the west, similar proofs exist of a movement up the glen, 
from the westward (see “Memoir on Parallel Roads,” Ed.inburgh 
Royal Society Transactions, vol. xxvii. p. 638).* 
(3) Craig Dhu, a hill situated on the east side of the gorge before 
mentioned, reaches to a height of 2100 feet, and presents several 
spots near the summit on its N.W. side, where the edges of the 
strata show smoothing from the north. The boulders on the hill 
are also chiefly on the north slopes. 
(4) Ben Chlinaig is a hill on the west side of the gorge, reaching 
to a height of 2545 feet. Mr Jolly of Inverness informed me that 
on its eastern slope he found rock striations at a height of 1840 
feet, running KW, and S.E. 
(5) In the gorge itself, near its lowest level, some of the rocks 
present large smoothings facing the northj and grooves of great 
length, evidently caused by violent and severe friction of heavy 
bodies which had moved over the rocks. 
(6) Then on the N.W. shoulder of Ben Nevis, at the mouth of 
* As these pages were being printed, I received from my old and esteemed 
friend, Colin Livingston of Fort- William, a letter (dated 23rd September 1884) 
narrating an excursion he had a few days previously made to Glen Gluoy, and 
mentioning that at a height of about 1750 feet above the sea he had found 
several granite boulders on the side of a hill facing the west, and lying on 
quartzite rocks, which were smooth on their west sides and rough on their east 
sides. He adds that three of these boulders formed a line or trainee of abou 
a 100 to 120 yards. He became satisfied, from these facts, that the boulders 
had come up the glen from the westward, and not down the glen, as he had 
previously supposed. The nearest locality for granite rocks, known to him, 
is ‘ ‘ Meallan-Suidhe, ” situated some miles to the westward.
