from N.W., and the boulder is hloched at its S.E. end by a rocky 
portion of the bill (as shown by Lithograph l^’o. 22, Plate IX.). 
At Castle Bay (at south end of Barra) the bills are covered with 
boulders, but more on their X.W. slopes than on any other. 
Mr Campbell {Paper on “ Glacial Phenomena of Hebrides'^) states 
that he took rubbings of strise at Castle Bay, which showed that 
striating agent had moved from X. by W. (magnetic). 
He mentions that on the small island of Berner a, about 12 miles 
south of Barra, he got striae at a height of 720 feet above sea, cross- 
ing the strike of the rocks from N.N.W. 
On hill called Scurrival, whose west side rises abruptly from sea 
to height of 240 feet, the hard gneiss rocks show proofs of a grinding 
action on them from X. W, The strata are horizontal, and form 
blocks with their longer axis lying about X. and S. The west sides 
of these blocks facing sea present frequent smoothings, especially at 
their north ends, whilst the south ends remain rough, showing action 
on the blocks from X.W. 
On this hill the boulders are numerous, and many of them are 
blocked at their S.E. ends. They are from 200 to 300 yards from 
the sea, and about 100 or 150 feet above sea-level The situations 
and positions of these boulders combine to show that they must 
have come here from a north-westerly direction. 
On the summit of the hill, which consists of well rounded and 
smoothed surfaces of gneiss, numerous boulders lie scattered, most 
of them on that part of the top which faces W.X.W. 
11. South JJist. — Xear south end, there is Carshavaule Hill, on west 
side of which is Loch Dunkellie. On east bank of loch, a gneiss 
rock well striated, — the striae running X.W. by X. At a little 
distance to S.E., on south of Carshavaule Hill, a valley through 
which current might have passed, after striating the rock. 
Loch Boisdale. — On east coast. Kennet Hill, situated on north 
side of loch, presents numerous examples on its west flanks of 
smoothed surfaces and of large boulders, many of them abut- 
ting on rocks at their east ends (see Diagrams in Fifth Report, 
p. 17). One of these boulders is 19x13x8 feet, 146 tons 
{Lithograph Xo. 23, Plate IX.). 
At junction of roads from Barra and Loch Boisdale, where Boman 
Catholic and Free Churches are situated, there is a cluster of
