I was informed by Mr Donald M ‘Neill, a very intelligent farmer, 
long resident on the island, that many of the boulders in that bay 
resemble yellow Mull granite. 
Mr M ‘Neill pointed out to me several boulders on his farm of 
Lower Kilchattan, which have distinctive names, some of them 
weighing from 2 to 3 tons. 
He also spoke of a large boulder on the west shore, about a mile 
to the south of Port Mor, between Dun Gallon and Ardskinnish, 
called Fingal’s Putting-Stone. 
He mentioned that at Kiloran, on the north-west part of the 
island, there is a sandy bay which leads to another bay called Port 
Shipness, where there are many boulders. 
Some large boulders are said to lie on the small islands to the 
east of Oronsay Island, where the old cathedral stands. 
On several ridges of Colonsay, sloping towards the west, boulders 
occur, as at Mullbuie and Schoolhouse Brae. Those on Mullbuie 
are about a ton in weight. 
All the hill tops are smoothed. On Carnan-re-Erium , the highest 
hill in Oronsay, there are said to be tracings of ice-markings ; but I 
had not time to search for them. 
In different parts of the coast there are shingle beaches composed 
of well-rounded, whitish-coloured hard stones, about the size of a 
man’s head, and under. Ships come sometimes to take away these 
stones, to be used for paving-stones. 
2. Notes by Mr Donald M i Neill, Loicer Kilchattan, Colonsay. 
(1.) At the north-east of the island, on the farm of Balnahard, 
there are granite rocks. 
At Scalasaig there is granite rock on the shore, and not far 
inland. 
The granite rocks in Colonsay are everywhere of a dark grey 
colour. 
(2.) The yellow granite used for building the harbour at 
Scalasaig was brought from Mull by ships — a distance of about 
12 or 13 miles. 
(3.) There are boulders in various parts of Colonsay,
