pushed for some distance before it was stopped. The west side is 
much rounder and smoother than any other side ; so, probably after 
it had stuck, the current which brought it, beat and chafed on its west 
side, and smoothed it. This boulder lies on a level plateau of rock 
about 202 feet above the sea. It is all open country towards the 
KW. and H.E., whilst the Kennet hill, reaching to a height of 
890 feet, is within half-a-mile of the boulder to the S.E. and E.S.E. 
On the west slope of this hill, at a height of 300 feet above the 
sea, the gneiss presents a rocky surface sloping down towards the 
west at an angle of about 10°. A boulder of coarse granite, 
7x6x4 feet, rests partly on it and on another smaller boulder 
underneath. This boulder, at its S.E. end, abuts against the rock. 
It has come, therefore, almost certainly, from some north-westerly 
point and stuck there. (Fig. 16 represents this case.) 
Hot far from the top of the hill, viz., at 712 feet above the 
sea-level, there is a very large angular boulder on a flat ledge of rock, 
on the H. W. side, with open country in that direction. This boulder 
is 19x13x8 feet. Its further progress eastward has evidently 
been stopped by a projecting cliff of the hill on its south-east side, 
as shown in fig. 17. 
3. Several large boulders may be seen at a small village, where 
the Free Church and Roman Catholic Church are situated at a junc- 
tion of the roads from Barra and Loch Boisdale, about two miles to 
the south of Askernish. There is here a whole cluster of boulders. 
One, 16x6x5 feet, leans slanting upon the others, and must have 
come from the H.W. to attain its position. 
4. On the hill to the east of Askernish, and on its side facing 
the west, there is a surface of rock, sloping down W.S.W. at 
an angle of 30°, well smoothed. A boulder rests on this slope, 
partly on the surface of the rock and partly on some smaller 
boulders which lie between the rock and it, near its S.E. end. The 
boulder has evidently obtained its position by coming from the 
N.W. 
This is more clearly proved by a number of ruts or striae, visible 
on the rock a few feet below the boulder, which run, as shown on 
fig. 18, by the arrows, in a direction from H.W. to S.E. That the 
striating agent first struck the rock from the N.W., is made evident 
by the circumstance that most of the striae are deeper and wider at
