the valley reaches to a height of from 300 to 350 feet. The 
bearing of this depression from the honlder is W.S.W., coinciding 
with the direction of the longer axis of the boulder. If the boulder 
had been carried to the spot where it now lies, from the westward, 
it would probably be by ice floating through the depression before 
referred to. For any land glacier the locality seems quite un- 
suitable. 
On our way back to Ardrishaig we observed, on the hills within 
sight of the road, many boulders. They lie most frequently on 
slopes facing some westerly point. Thus, on a hill called Leck-na- 
Banf on the north side of the road, at about 300 feet above the 
sea, where the slope is towards W.S.W. at an angle of about 10°, a 
boulder 10x8x6 feet is lying on the edge of vertical strata, the 
boulder being a light-coloured fine-grained crystalline gneiss, while 
the rocks on which it lies are a soft slaty schist. 
Near the Crinan Canal at Ballanoch, on the hill above the high 
road, and about half a mile from the canal, there is a boulder 16 x 
9x9 feet, at a height of about 300 feet above the sea. It lies on 
the north side of the valley through which the road passes. The 
general direction of the valley is N.E. by N. and S.W. by S. The 
longest axis of the boulder coincides with the direction of the valley. 
The boulder is lying on bared rocks. It seemed probable that ice 
carrying boulders had floated through this valley, and lodged the 
boulder. 
l^th July 1882, Ardrishaig Hotel. — In the Seventh Boulder 
Report, p. 10, a very partial account was given of smoothed and 
striated rocks at Kilmory, at the western extremity of the tongue of 
land dividing Loch Killesport from Loch Sweyn. I therefore re- 
turned there, to examine the spot more minutely, in company with 
Mr Alexander of Lochgilphead. 
At Ardna, Mr Macmillan’s farm, I saw again the large expanse 
of these interesting rocks. 
The extent of rock surface, horizontally, is about 13 yards, and 
vertically, about 5 yards. The surface in different parts slopes down 
towards S. by E. — S. — S.S.E. — and S.E., at angles varying from 30° 
to 40°. They have been most severely rutted, on the slopes which 
face S. and S. by E. Where the surface slopes down S.E. it is not 
striated, only smoothed ; showing that the striating agent did not
