banks of the loch, threw these great stones at one another. It is 
said that on the west bank of the loch, near Strome Point, and 
almost immediately opposite to “ Craig na Calleach,” there is a 
boulder of about the same size — -which, however, the Convener was 
unable to go in search of. “ Craig na Calleach ” is a compact schist 
of a light grey colour, with thick nodules of quartz in it. The 
rocks of the beach on which the boulder lies are a slaty schist of a 
greenish blue colour. A sketch was taken. 
(4.) On the farm of Acli-na-foud , situated about a mile from 
“ Craig na Calleach/’ there is on the slope of a hill an angular 
boulder. It is at a height of 222 feet above the sea, and on the 
edge or verge of a precipitous bank. It rests partly on rock, 
and is in a very critical position. If the bank be now in the same 
condition as when the boulder was deposited, it must have been let 
down very gently or gradually, to avoid receiving an impetus which 
would have caused it to roll down the bank. A sketch was taken. 
BERWICKSHIRE. 
In the parish of Dunse the boulder clay has lately been cut through 
for some hundred yards to make a new road, and to a depth of 8 or 
10 feet below the surface of the boulder clay. Beds of gravel and 
sand lie over the boulder clay, in some places to the thickness of 1 2 
feet. On an inspection by the Convener (November 1877), in com- 
pany with Mr Stevenson, Dunse, boulders in the clay were recog- 
nised as having all come from the west, chiefly W. by N. The 
Kyles Hill and Dirrington Hills porphyries were among these ; the 
former is three miles W. by N., the latter six miles W.N.W. 
There were also sandstones with fossils, which Mr Stevenson 
knew to have come from a sandstone rock a few hundred yards to 
the westward, and which he pointed out to the Convener. The 
fossils were the ordinary plants of the coal formation, and an 
annelid.
