smooth surface. Direction of abrading forces there is from N.N.E. 
Eemarked that, “ in this case, glacier action impossible ; ” and that 
apparently the peak had been a rocky islet, on which floating ice- 
bergs drifted. 
“On some of the lower ridges, towards Loch Fyne, there are 
remarkable examples of large blocks of granite perched upon the 
very summits, in positions which it is impossible to suppose them 
to have attained, by any other means than by transportation upon 
ice ” (Duke of Argyll, Proceedings of Royed Society of Edinhurgh^ 
vol. hi. p. 457). 
Loch Awe. — (1) About a mile south of Port Sonnachan, a perched 
boulder of compact gneiss, 13x12x6 feet, stands on a narrow 
ridge of soft mica schist, in a peculiarly precarious position. Its 
longer axis and S. Its height above sea 1026 feet. Sides 
of hill to the ridge, so steep, that Convener could with great 
difficulty climb up to the ridge. There being no higher hills near, 
supposed that boulder could have come only by floating ice, and 
from north, where there is the greatest opening {Lithograph No. 7, 
Plate VIII. {Sixth Report, p. 8). 
(2) On hills to eastward, about 900 feet above sea, the slopes facing 
north are well covered by boulders. The largest, 18x10x10 feet 
(130 tons), has its longer axis lying N, and S. {Sixth Report, p. 10). 
Brander^ Pass of. — On its east side two terraces, at 68 and 
his colleagues of the Boulder Committee, and that the Convener is free to 
refer to the paper in any way. 
The Convener thinks very highly of Mr Anderson Smith’s paper, and especi- 
ally of the illustrations. But he does not feel justified in detaining it, as the 
meetings of the Glasgow Geological Society for the present session will prob- 
ably soon terminate. The great value of Mr Anderson Smith’s illustrations 
may be judged of even from the mere titles of a few of them. 
(1) Granite Boulder (12 to 15 tons), a few feet from the top on northern 
face of a hill over Loch Creran; greatest diameter 10 feet N.W, and S.E. ; 
smallest end N-W. 
(2) Boulder on Table land, below the above (10 tons); N.W. and S.E, ; 
smallest end N.W. 
(3) Black Granite Boulder (10 tons) ; greatest diameter 8 feet, lying N.W. 
and S.E. ; smallest end N.W. 
(4) Grey Granite Boulder, over Barcaldine Gardens, 400 feet above sea, 
19 X 12 X 7 feet ; longest axis N.W, and S.E. 
(5) Grey Granite Boulder, 300 feet above sea ; 13 x 7 x 5 feet ; longest 
diameter N. and S. 
(6) Ardchattan Boulder (mentioned in this Committee’s Report) is in one 
of the illustrations represented as partly buried in moss, and weighing about 
50 tons.
