Visited “Split Boulder,” first mentioned by Smith of Jor- 
danhill. A claystone trap, similar to rock of island. Lies at 
sea-level on rocks smoothed and striated, forming east side 
of a trough or valley running N.E. by N. Strise run same way. 
Dumbarton. 
Luss. — Mica-schist boulder on west bank of Loch Lomond, 
26 x 18 x 7 feet; about 250 feet above sea-level. Situated on 
a brook entering Fruin Water, west of Callendoun Farm 
House. Longer axis E. and W., with sharp end to west 
and thick end to east. Bocks adjoining, old red sandstone. 
Nearest mica-schist hills to north and west, about 5 miles off. 
Keporter remarks, that if boulder came from W. or N.W., it 
must have crossed hills from 1000 to 2000 feet high. But it 
may have come from north, down valley now occupied by Loch 
Lomond, on ice which floated it so far south, and then carried 
it west up Grlen Fruin. — (B. L. Jack, F.Gr.S., Alexandria.)

Dyke . — Near west end of approach to Darnaway Castle, several 
granite and gneiss boulders from 2 to 3 tons each. 
In same parish, near west lodge to Darnaway Castle, a 
kaim, quarter mile long, running N. and S. 12 feet above 
general surface. (Captain White, B.E.) 
Elgin . — Boulder called “ Carlin’s Stone,” onBogton farm, — a coarse 
conglomerate, about 230 feet above sea. Imbedded pebbles, 
chiefly flesh-coloured quartzite. 
About half a mile to N.W. a sm aller boulder, called “ Young 
Carlin’s Stone.” 
Conglomerate rock occurs in hills to south, distant 5 or 6 
miles ; but of a variety different from that of boulders. Same 
variety of conglomerate as the boulders exists beyond Inver- 
ness to W., and in Boss-shire to N.W. 
From size and shape of these conglomerate boulders, evident 
they must have been carried or rafted. 
On other hand, in this district hundreds of round and smooth 
boulders of granite, gneiss, mica slate clay, slate, &c., whose 
shape and smoothness indicate that they have been pushed
