vertical cliff of rock, about 60 feet above the River Awe, on 
Cruachan, which did suggest glacier friction; and at a height of 334 
feet above the sea, above Inverawe, the Convener found rocks which 
seemed to have been smoothed from the W.S.W. But above that 
height the rocks presented smoothings successively from N.W. by 
N., from N.N.W. and W.N.W., — the W.N.W. being in the highest 
parts of the hill, apparently the most persistent direction. 
(9.) The Convener afterwards proceeded to the head of Loch Etive 
in a steamboat, and then travelled by coach nine or ten miles to the 
head of Glen Etive, to a height of about 600 feet above the sea. The 
whole of this valley has at one time been filled with gravel and 
boulders of grey granite. A great part of this mass of drift had 
apparently been scoured out by the action of the numerous streams 
which descend from the high steep mountains on each side of the 
glen. Terraces were occasionally visible on the south side of the 
glen, up to a height of about 500 feet above the present channel of 
the river, consisting of clay, gravel, and sand, which may have been 
the bottom of an estuary in former times. 
XII. LOCH CRERAN. 
The Convener paid a visit to Loch Creran, having last year 
seen that there were there more objects of interest than he had then 
been able to overtake. 
At the mouth of Loch Creran, where it joins the Linnhe Loch, 
the rocks are all smoothed when they face the W.N.W. at about 70 
feet above the sea, and also at Craigan Ferry. But about a mile 
higher up the loch, the smoothed rocks face W.S.W. , at a height of 
about 80 feet above the sea. 
Near the sea-level, the smoothing of the rocks seemed attributable 
to the action of some force moving down the valley, whilst rocks at 
a higher level, say 100 feet and more above the sea, grinding from 
the N.W. — i.e.y up the valley — seemed undoubted. 
On going up the glen towards Carroban hill, notice was taken of 
a trainee of boulders which, appeared to go over a summit level to 
the east of that hill. The boulders are all of a dark-coloured fine- 
grained granite, and are apparently the same as the Fasnacloich and 
Appin boulders referred to in last year’s Report. Mr Hall, the 
intelligent tenant of Fasnacloich, who from boyhood has lived in
