Several boulders were pointed out. Two were of a species of trap 
common in the Kilpatrick Hills, situated some miles to W.K.W. 
Another boulder was a grey granite, which, judging from the size of 
its felspar crystals, Mr Young supposed might have come from Ben 
Awe, a mountain situated to N.W., and distant about 30 miles. 
There were also several Conglomerate boulders, derived probably 
from the belt of that rock, which, running from Dumbarton, crosses 
Loch Lomond in a K.E. direction towards Aberfoyle. 
The Convener at another time, when on Campsie Hills, found 
rocks at 800 feet above the sea, striated in a direction E. and W. 
On the Kilsyth Hills, a few miles further east, the rock striae point 
the same way. 
On Croy Hill, a knoll of trap rock, being the summit level between 
the Eirths of Clyde and Eorth, about 160 feet above the sea, there 
is an immense accumulation of boulders. Some of the boulders are 
of old Conglomerate, which must have come from the westward 
and stuck on the knoll {Fourth Report, p. 42). 
The relative positions of these localities may be more readily 
understood, by referring to the annexed map.
