the striae would have been widely different, had the island radiated 
its own ice, and had the glaciation been purely local ” (p. 791). 
“ Tor these various reasons, we are justified in inferring that the 
glaciation of these outlying islets is due to the action of an ice-sheet 
originating far beyond the sphere of Shetland,” (p. 792). 
“ The highest ground in the centre of the Mainland is likewise 
ground down and striated. The ridge which extends from Weesdale 
Hill (842 feet) to Scallafield (916 feet) reveals the fine lines as well 
the flutings of the ice-chisel ” (p. 793).

1. Alloa. — Basaltic boulder, 13x12x11 feet, called ^Mlair 
Sto7ie,” about 7 0 feet above sea. Longer axis N. and S. Assuming 
boulder to have come through valley ox kyle, between Abbot’s 
Craig and Damyat, it must have travelled in a direction from N.W. 
by W. {First Report, p. 50). 
2. Kilsyth and Strathblane. — Mr Jack, of Scotch Government 
Geological Survey, reported two boulders, — one of mica slate, weigh- 
ing about 6 tons, 1260 feet above sea, its parent rock supposed 
by him to be to the N., and distant 15 miles. The other boulder 
is Conglomerate, 8x4x3 feet, its longer axis being W. 20° N., 
its parent rock supposed by him to. be also to N.W. {First Report, 
p. 51). 
3. Campsie. — Mr John Young of the Hunterian Museum, Glasgow, 
accompanied Convener to an inspection of the district near Campsie, 
and pointed out the following objects of interest : — (1) On Craigend 
Moor, about 450 feet above sea, sandstone rock presented great 
sheets of smoothed surface, evidently ground down by severe or 
long-continued friction, with occasional striae running S.E. by S. 
In some places there were quartz pebbles in the sandstone rock, 
which were ground down, showing marks of rubbing chiefly on the 
N.W. sides. 
At four other places there were striations on rocks, pointing re- 
spectively S.E. by S. and S.E. J S., S.E. by S., S.S.E. 
Looking from this moor towards the IST.W., hills are seen about a 
1000 feet high, at one place with an opening between them of about 
IJ miles in width, through which, if there was a current, it might 
pass over Craigend Moor.
