6x4x4 feet, very angular, of gneiss, evidently also brought 
from westward. Several quartz boulders on hill, which also 
must have come from westward. (Convener.) — (See Plate, 
Sketch No. IV.) 
Clunie. — Gneiss houlder 8x5x4 feet, with longer axis S.W. 
Gneiss boulder 10 x 6 x 5 feet, with longer axis N.W. Both 
boulders on tops of knolls, and must have come from Grampians 
5 or 6 miles to N.W. down a valley. First boulder called 
“ The Grey Stone.” Height about 320 feet above sea.— 
(Robert MHeish, schoolmaster.) 
Dunkeld. — Craigiebarns Hill, to N.E. of town, visited; made it 
about 1000 feet above river Tay at Dunkeld Bridge, and about 
1250 feet above sea. 
Several boulders of mica-schists at and near top of hill, but 
chiefly on sides facing N.W. Bocks in situ also mica-schist, 
but not the same variety as boulders. 
These boulders mostly angular and sharp in edges ; only one 
or two rounded ; among these one of a hard brown sandstone. 
Greater number of boulders perched on top or sides of knolls 
than in hollows. Agent which transported them had been 
of such a nature as to be interrupted in its progress by knolls, 
and made to discharge its cargo of boulders on them. (One of 
these boulders shown in Plate, Sketch No. X.) 
On this hill, rocks smoothed and striated in numerous 
places. These markings, when examined minutely, show 
a movement over the rocks, to produce them, from N.N.W. 
The longer axis of boulders, generally N.N.W., which is 
towards head of valley. But whether a glacier occupied valley, 
or floating ice, not clear. 
On Craigiebarns, gravel found at the highest points. 
On descending hill towards the river, observed on rocks 
the following directions of striae, at the height specified : — 
At 972 feet above river, striae, direction of, N. by W. 
„ 700 ,, ,, ,, N-^-E. 
„ 648 „ „ „ N. by E. 
„ 288 „ „ „ N. by E. 
The axis of the valley at this place N.E. ; therefore agent 
which produced striae, seems to have been of such a nature
