height of about 360 feet above sea, clay slate rocks smoothed 
and striated in a direction from N.W. by 1ST. 
Fell in with two boulders lying near each other on side of 
hill, sloping down to W.N.W., where sea situated, about one 
mile distant. In one case, boulder lying on clay slate rocks ; 
in the other case, boulder so sunk that base not visible. First 
boulder 8 x 6-J x 4 feet. Longer axis N.W. Second boulder 
9x5x4 feet. (Shown to Convener by James Baird of Cam- 
busdoon.) 
Both boulders apparently came from N.W., and intercepted 
in further progress by hill. 
Fell in with another boulder, which broken into two frag- 
ments. Configuration of district indicates that it must also 
have come from N.W. Smaller fragment lies from rest of 
boulder at a distance of 4 or 5 feet and to S.E. A study of 
fragments creates impression that boulder has been broken, 
not by action of frost, but by falling from a height, which 
caused concussion. 
On shore to west of Inverie House, several boulders of 
coarse granite, similar to Fort-William and Cluny MTherson 
granite. These Inverie boulders supposed to have come from 
Dunedin and Cairnmore Hills, about 10 miles to eastward, and 
at head of valleys opening to west coast. Opinion expressed 
to Convener that these boulders not so likely to have come 
down the Dhulochan valley as the Loch Nevis valley. 
At Invergussern (about 8 miles north of Inverie), the valley 
has been, at its mouth near the sea, crossed by an immense 
embankment of gravel and sand, about 30 or 40 feet deep, 
lying over rocks. 
The river has cut through this embankment, and also a 
portion of the rocks covered by it. 
This embankment probably terminal moraine of a glacier 
or a submarine deposit, more probably the latter, as sandy, 
and in some places stratified. Its ridge is about 140 feet 
above sea. At one time it has served purpose of a dam to 
keep in lake, the successive levels of which are seen on both 
sides of valley. 
At summit-level between Inverie and Gussern, viz., from 400
