of Edinburgh, Session 1878 - 79 . 
At a height of 1683 feet, about 11 feet below the summit, 
smoothed rocks were still found sloping gently towards the 
south. 
On descending the hill towards the north, by a more westerly 
path than that followed in ascending, it was observed that, at a 
height of 1554 feet, the smoothed rocks faced the north. 
Some of the boulders met with on the descent were of the same 
dark purple porphyry seen at Lailt. 
(5.) On reaching Loch Etive, the Convener visited the Airde point, 
a projecting cape or headland on the west side of the loch. At this 
point there were many well-smoothed rocks up to a height of 276 
feet above the sea, and facing up the glen towards Loch Awe. There 
can be no doubt that these rocks had been smoothed by glacier action. 
On this Airde point there were numerous boulders, chiefly of grey 
granite. They may have been pushed down the glen by a glacier ; — 
indeed it seemed the most probable supposition. But they might 
have been floated up from the N. W. None of the boulders seen 
were in such a position as to indicate with any certainty the quarter 
from which they had come. 
It may be added that the rocks on the south shore of Loch Etive, 
as far down as Connel ferry, and even lower, show smoothings all 
facing up toward the head of the loch, suggesting glacier action 
from the upper part of the valley. 
(6.) In the Eourth Report by the Committee (p. 11), reference 
was made to boulders observed in the Island of Kerrera , at the 
north end. This year the Convener had an opportunity of exa- 
mining the boulders in the middle of the island, where it is 
traversed by the high road leading from Ballimore farm to the 
ferry for Mull on the west side of the island, called “Bal-na- 
Bok.” 
On his way across the Island, he had pointed out to him by Mr 
MDougal, tenant of Ballimore farm, three or four well-rounded 
boulders of a coarse granite, having a red tinge, imparted from the 
felspar crystals. They were from 2 to 3 feet in diameter. Mr 
Mfldougal stated that there was no granite rock in Kerrera which he 
knew of ; and that the nearest place where he had heard that granite 
of that kind was worked was at Morven, about 12 miles across the 
sea to the north. He was sure it was not the same as any he had
