before referred to, had probably to a certain extent protected the 
bay from any influx of boulders. If the transport of the boulders 
was due to ice floating on a current of the sea from jST.N.W., this 
may have occurred when the sea stood several hundred feet above 
its present level, in which case the Kildavannan ridge might still 
have acted in the way now suggested, as it runs up the land, in a 
north-easterly direction, to a considerable distance. 
All along the part of the west coast just described, the 40 feet 
old sea-margin is exceedingly distinct. Those at higher levels, seen 
elsewhere on the West Coast of Scotland, were not observed in 
this part of Bute. 
3. On the following day the Convener, under the guidance of Mr 
Millar, paid a visit to Barone Hill, situated about 2 miles to the 
S. W. of Bothesay, and reaching to a height of about 530 feet above 
sea-level. Plate II., fig. 2, gives a sectional outline of the hill in an 
east and west direction. The hill was first approached by us from the 
eastward, and there was a close examination of the bare rocks on 
the north side in search of smoothed faces. One or two were found, 
though not of so decided a character as to deserve special notice. 
Beyond the principal hill, about half a mile farther west, there is 
another hill, reaching a height of about 430 feet, with a gully 
between the two, on which Mr Millar discovered markings of a very 
interesting character, and called to me to come and examine them. 
This gully is about 30 yards wide, having sides of bare rock more 
or less vertical — the rocks on the east side higher than on the west 
side. On entering this gorge (A figs. 2 and 3), it was at once seen 
that something had passed through it from the north, leaving unmis- 
takable traces. What first attracted attention was the smoothing 
of the rocks at d on the principal hill, and on the opposite side of 
the gorge at eee (see figs. 2 and 3 in Plate II.). 
On the west side of the gorge, the number of places ground 
down and smoothed are more numerous, one reason for which 
might be that the rocks appeared less hard than on the opposite 
side. On that side, there are some isolated patches of rock, well 
smoothed, because they had apparently encountered the full force 
of the agent which had passed through the gorge; but there are 
other patches, as at /, quite rough, because apparently under the 
shelter of others.
