feet. There is only one boulder on . the north side, viz , b, whose 
size is 9 x 4 x 4 feet. They are all gneiss boulders. 
As bearing on the question of transport, it is proper to mention 
that this hill stands by itself, in a sort of amphitheatre. There 
are no hills so high as it within a mile. 
At about that distance towards the north, there is a range of hills 
somewhat higher, — with openings between, especially towards the 
west. On these hills, numerous boulders were descried through the 
telescope, and regret was felt at the inability to visit them,— 
especially as several were seen perched on ridges and peaks. 
It seemed probable, that if there had been ice carrying boulders, 
floating on a sea from 800 to 1000 feet above the present sea-level 
and stranding on the hill, the position of the boulders on the hill and 
its sides might be accounted for. 
In this district, with hills, none exceeding 1200 feet in height, 
local glaciers are not likely to have been formed ; and if there had 
been such, they would have passed down the low grounds on each 
side of the hill along its base. 
On his way back to Tarbert, the Convener passed a conical hill, 
on south, clad with smooth green pasture. On its JST.W. slope, two 
large boulders were observed. But as the access to the hill was 
difficult, the Convener did not attempt to reach it. 
The hills, both north and south of East Tarbert, are well covered 
by boulders, and would repay a special visit from any one interested 
in this subject. Even from the streets of the town, in a clear day, 
boulders can be seen along the ridges of the surrounding hills on the 
sky-line. 
On the hills adjoining East Tarbert village, on the south, and at a 
height of from 280 to 300 feet above the sea, there are evident marks 
of some agent having swept through between the hills from west to 
east. The rocks are well rounded by friction; and on the east side 
of many rocky knolls, there are small boulders, and heaps of gravel, 
which look as if they had been protected by these knolls from a 
westerly debacle or current. 
The Convener, when at Rothesay, walked along the course of 
the small stream which runs into the sea near the Queen’s Hotel. 
In the lower part of its course, the stream cuts through beds of 
gravel, from 50 to 60 feet thick. In the upper part of its course he
