Diagram 5 is a ground plan of the surface on which these boulders 
lie , — h is about 100 feet above the sea, and d about 60 feet; h, d 
representing a ridge running about W. by 8. and E. by N., with 
the surface sloping gently down on each side towards the north and 
south respectively, as shown by arrows and the letters e, /. Much 
of this rocky tongue on which the boulders lie has been ground 
down to a smooth surface. 
The site of the largest boulder B represented is shown in diagram 
5 on the northern slope at B. 
The greatest number of boulders deposited is on the northern 
slope (diagram e, a, h), as if they had come from some north-westward 
point, and had been intercepted by the slope. 
The position of these boulders, especially of the largest, renders 
it more probable that they came by floating ice from the sea, than 
by a glacier from the land. 
Learnt from the shepherd’s wife, an intelligent woman, residing in 
the offices of Taynish House, that there are two other large boulders 
at or near the shore, about 300 yards south of Taynish House ; 
but bad weather prevented a visit to them. In the policy of 
Taynish, close to the avenue, about half a mile to the east of the 
house, we observed many boulders on a hill side, sloping down to 
the north, at about 200 feet above Loch Sweym 
On our return to Ardrishaig I visited again the large boulder at 
Loch MhurHch, mentioned in the Sixth Keport, p. 16. Ascer- 
tained that the depth or vertical thickness of the boulder was, at its 
east end, 1 2 feet, and at its west end, 5 feet ; its narrowest end 
being therefore towards the west. Its longer axis, which is W.S.W. 
and E.H.E., slopes down towards the west. 
The situation of this boulder, relatively to the adjoining hills, is 
shown in diagram 6, where B is the houlder and H rocky hills sur- 
rounding the valley, with small boulders scattered over them, 
shown by dots. These hills rise to the height of from 200 to 
300 feet above the sea. 
When looking from the boulder towards the west, a range of 
low hills is seen crossing the valley, about half a mile distant, and 
in that range a depression occurs, through which the road passes, 
leading westward to Keills. The summit level of this depression is 
about 100 feet above the sea, whilst the rest of the range crossing
