surface looks northwards, the smoothing agent must have come 
from some northerly point. 
(8.) At Ardbeg, north of Rothesay, there are many boulders on the 
shore — one 9x8x5 feet, another 10x7x5 feet ; one is quartz or 
chlorite schist, the other trap. The rocks in situ are chloritic slate, 
dipping S.E. 56°. First-mentioned boulder has its longer axis 
pointing N.W. and S.E. 
(9.) Near the head of Port Bannatyne Bay, there are hundreds 
of boulders on the shore seen at low water, all well rounded. Those 
which are long shaped generally lie S.E. and N.W. 
Near the head of Port Bannatyne, in a field about 30 feet above 
sea-level, there is a coarse schist boulder 4x2x2 feet, one side 
finely smoothed, with ruts on it parallel to longer axis. 
(10 .) At Ardmaleish Point (entrance to Kyles of Bute) there 
are many schistose boulders, some coarse and pebbly, others fine- 
grained. The largest is 8 x 8 x 6 feet. They lie on blue slate rocks. 
(ii.) At north end of Bute, opposite to Colintraive, the rocks, up 
to 230 feet above sea-level, are rounded and smoothed. They con- 
sist of mica schist, in some parts coarse and pebbly. Some of them 
quite resemble the boulders at and near Ardmaleish Point. 
At 380 feet above sea-level, the rocks are smooth on their sides 
facing the N.W., but rough and fissured on their eastern sides. 
Blocks lie below them on these east sides. 
(12.) Around Bull Loch, the rocks, at 560 feet above sea-level, 
are well smoothed, and form a steep wall facing N.W. 
(13.) Notes applicable to district abtmt 3 miles south of 
Rothesay : — 
(a.) Ascog Loch , about 100 feet above sea-level; at north-east 
end, a great number of schistose boulders ; at north-west end, a large 
quantity of schistose stones. The rocks m situ here are red con- 
glomerate. 
(5.) Loch Fad . — On the N.W. of this loch, there is a hilly range 
running N.E. and S.W., and reaching heights of from 400 to 450 
feet above sea-level. In one part, there is a gorge through which 
something has passed, smoothing and striating the rocks. The strise 
point S.E. and N.W. On the south slopes of this range, lie a number 
of blocks which seem to have been, transported, being too distant 
from any cliffs from which they could have fallen by mere gravitation.
