II. lith July 1882, Ormsary House (on south hank of Loch 
Killesport), Argyleshire, residence of Mrs Campbell. — Set out, 
under the guidance of Mr Alexander, to visit Olacli Briach 
(stone-spotted hill), on which he informed me I would find a 
number of large boulders. 
This hill being situated a few miles to the east of Ormsary House 
we had to pass the “ Big Boulder ” near the high road, described in 
a previous Report (Sixth, p. 14), and illustrated there by 
diagram 5. 
I was again struck with the fact, that at this spot there is a 
great multitude of boulders, several of them touching one another. 
I counted ten, occupying a space less than 2 acres in extent ; one 
of these (apparently not mentioned in the previous Reports) meas- 
ured 16x12x8 feet. 
Mr Alexander informed me that on the hills along the south side 
of Killesport, ivesf of Ormsary House, there are no boulders; and that 
they occur only on the hills to the east of Ormsary House, with 
the exception of two on the sea-heach. The only peculiarity which 
I discovered in these respective hills was that to the west of Orm- 
sary the sides of the hills facing Loch Killesport are excessively 
steep, whereas the hills to the east of Ormsary slope more gently to 
the Loch, and are not so high. If the boulders were brought on 
floating ice from the W., or W.K.W., would the last-mentioned 
hills, because of their more gentle slope, not have more readily 
arrested the ice, and have afforded sites for boulders when the ice 
melted ? 
We passed through a valley called Baronlungart, running E. and 
W. between Ormsary and Aclioos. In the bottom of the valley 
there are several spots where the rocks are beautifully ground down 
and smoothed, evidently from the westward. This valley is about 
60 feet above the sea-level. A few boulders are lying in the 
valley. 
Having reached the shepherd’s house, on Clach Briach hill, I 
mounted a horse and followed a peat road for about a mile in a 
westerly direction, till we reached a level of about 400 feet above 
the sea, and came to a place from which we could look down to the 
north on the farmhouse of Tign-a-Kaim. The hill, along the ridge 
of which we had ascended, terminated at this place in a rounded
