Bute. 
1. W. J. Millar, C.E., Glasgow, having, during the last two years, 
had occasion to he frequently in Bute, and having taken notes of the 
boulders lying about the coast near Rothesay , and to the north of it, 
had the kindness to draw out for the Committee the following list of 
boulders observed and studied by him. 
(1.) On the shore to the east of Rothesay, at Glenburn, a chlorite 
schist boulder 6x5x5, with large veins of quartz, weighing pro- 
bably about 7 tons. It rests on the red conglomerate of this part 
of the island. 
(2.) Near Craigmore pier, east of Rothesay, about 30 feet above 
sea-level, a boulder of very coarse pebbly schist, about 3J feet long, 
well rounded and smoothed on lower side. It was near the mouth 
of a disused whinstone quarry, among conglomerate gravel. 
(3.) Farther east, and south of a point of land a little below high- 
water mark, there is a boulder of trap, 6 feet long, resting on 
red conglomerate rocks. 
(4.) On ascending the hill from the last-mentioned place, several 
micaceous schist boulders are met with, two measuring about 3 feet 
across, one about 70 feet, and the other 120 feet above sea-level. 
(5.) Still farther up the hill, and on road towards Rothesay 
through a wood, at 150 feet above sea-level, there are many schist 
boulders, well rounded and smoothed, some about 3 feet in length. 
At 180 feet above sea-level, there is a coarse schist boulder 5 x 2J 
feet, one end round and smooth, the other end rough and angular 
— longer axis E.N.E. by compass. 
(6.) Nearer Rothesay, on same road, at about 200 feet above sea- 
level — a mica schist boulder, about 6 feet long, rounded at one end 
and rough at other end. 
(7.) In great sandpit above and behind Queen’s Hotel, Rothesay, 
a mass of coarse gravel lies above sand, forming a bed about 1 2 feet 
thick. The underlying sand is of unknown depth, but a face of it is 
seen for about 30 feet vertically, with a length of about 200 yards. 
Several boulders of gneiss occur in the sand, the largest about 
5x3x2 feet. North-west of this sandpit, and near it, there is a 
smoothed rock about 120 feet above sea-level. As its smoothed
