of Edinburgh, Session 1878 - 79 . 
The Ordnance Surveyors having reported to the Boulder Committee 
a very large boulder seen by them at the foot of Glencoe, and having 
had the goodness to indicate its exact position on their map, 
the Convener made an attempt to find and examine it. On the 
map the boulder is indicated by the name of “ Craig Bhutan,” which 
it is believed means “ rock with trees” The Convener saw the 
boulder, at the distance of about a quarter of a mile, with bushes 
growing on it; but he was prevented reaching it, in consequence 
of being unable to ford a river between him and it. The size 
of the boulder was stated by the Ordnance Surveyors to be 90 
feet in circumference, and about 10 feet high, and it appeared to 
the Convener to be of that size. It lies in a meadow adjoining 
the Biver Coe, about half a mile to the S.W. of the Glencoe Hotel. 
The meadow is about 200 feet above the sea, and is closely sur- 
rounded by mountains exceeding in height 2000 feet on all sides 
except two. One of these sides, to the east, is the valley of 
Glencoe. The other side, to the north, is the valley leading to 
the sea at Loch Leven, distant about 13 miles. 
As the boulder seemed to be resting on an extensive mass of 
gravel, it seemed to the Convener very probable that it had come 
from the north, i.e,, up the Loch Leven Valley. 
On the right bank of the River Coe, nearly opposite the large 
boulder just referred to, there is a rocky knoll standing from 20 to 
30 feet above the adjoining district. This knoll has had lodged on its 
north side, a number of boulders, whose relative positions indicate 
transport from the north, i.er. , up the glen. One of these is a dark 
micaceous rock, glistering with abundance of mica. A few hundred 
yards to the north of the knoll, there is a rocky conical hill, reaching 
to a height of about 90 feet above the adjoining district. It is on the 
map called “ Tom a Grianain.” It consists of vertical strata of mica 
schist, — the only place where, in the course of this day’s perambula- 
tion, that kind of rock was seen. There can be little doubt, there- 
fore, that the mica schist boulder just mentioned had come from 
“ Tom a Grianain,” i.e., from the north, and been torn from the hill 
by floating ice. 
The facts ascertained in Glencoe seem to indicate two separate 
agencies. In the first place, there was a glacier, which planed down 
the rocks, so as to produce the extensive smoothings and groovings
