dilatation, it would fall to pieces, altogetker in the valley, before it 
could reach the position of the kaims. 
At the same time, I am far from denying that Mr Jamieson had 
good grounds for supposing that a small glacier existed in Glen Treig, 
and that it even probably protruded a little way into the valley. 
In his map he indicates glacial striae at a point where they may 
have been caused by a glacier from Loch Treig. I saw these striae, 
(Notes, vol, i. p. 8), viz., on masses of rock which had been 
smoothed and partially striated from the westward. Most of the 
rock was covered and concealed by detritus, which, on being cleared 
away by me, showed the smoothed surface of the rock. The 
explanation which occurred to. me at the time was, that after these 
rocks had been so smoothed and striated the country became sub- 
merged, and the whole valley was filled with submarine beds of 
gravel, sand, and boulders. The spot now referred to is near that 
marked “ ” on the onednch Ordnance Map (Sketch Map, 
Plate XL). 
Whilst offering my opinion, that these kaims in Spean valley 
are submarine detritus, and have been scoured out into long banks 
by the action of sea currents, I acknowledge that they deserve 
much more examination than I had the opportunity of giving; 
and I trust others who are interested in these researches will visit 
the locality, and publish the results of their inspection.^

In the Fifth Eeport (page 23) of the Boulder Committee it is 
mentioned that “ at Borve^ on the west coast of Harris, about half- 
way between Eodel and Tarbert, there is a remarkable accumulation 
of boulders on the side of the hill sloping down to. the sea. The 
general slope of the hill (which reaches a height of 800 feet) is 
towards W. by X. (magnetic). The rocks are of gneiss, and present 
a series of beds, layers, or benches more or less horizontal, forming 
as it were a gigantic staircase along the hill face, for about half a 
mile, all more or less covered by boulders. These benches of rock, 
in many places, show that they have been rounded by severe pres- 
sure from W. by N. Many of the boulders which lie on them also 
give evidence of transport from the west.”
