Its position also is precarious, and suggests a doubt whether, 
when brought here, it could have been deposited on the precise 
point where it now stands. There was nothing to indicate the 
direction from which the boulder had come. 
3. There is another boulder on the right side of the valley, about 
820 feet above the sea, 12x15x7 feet, fig. 4, Plate I. 
It lies on a shelf near the ridge of a hill, and close to a slope 
of the hill which rises up from the boulder, and facing the 
H.W. The spot suggested the idea that the boulder had been 
brought from the H.W., and that this hill stopped its further 
progress. There is towards the H.W. an opening among the hills 
through which it might have been floated towards its present site. 
4. A little lower down the valley (Rossdale), and on the same 
side, at a height of about 630 feet above the sea, there is a rocky 
knoll somewhat flat on the top, and presenting an area of about 
8 or 9 yards in diameter, on which are five or six boulders lying 
pretty close together, as shown on fig. 5, Plate I. The boulders are 
granite, the knoll is mica schist. 
5. At a still lower part of the glen there is a steep hill sloping 
down to the river. Hear the top of this hill, and on the very edge 
overhanging the river, a boulder rests at a height of 300 feet 
above the river. The boulder is of granite, about 20 feet in 
diameter. It rests on mica slate rocks, which form a smooth surface 
sloping down towards the river at an angle of about 30°. Its posi- 
tion indicates transport from the north, as the land there is low 
enough to have allowed it to be floated over, whilst high hills to 
the south exclude that direction. 
In the valleys where these boulders lie, there are some remark- 
able terraces. They were made known to the Convener by 
Captain Burke, RE., two years ago, when he was still at the 
head of the Scotch Ordnance Survey. The surveyors employed in 
drawing the contour lines for the maps were struck by the hori- 
zontality and continuity of the terraces. Captain Burke was 
so obliging as to draw on the Convener’s map lines to indicate 
their position. As these terraces suggest important views bearing 
on the position of the boulders, and their mode of transport, it 
seems not irrelevant to record the notes supplied by Captain Burke 
and give a copy of the map, to show where the terraces are.
