ning in a N.E. and S.W. direction. They open into Loch Swin, 
and are well filled by boulders. These are generally most abun- 
dant on the south sides, and on the slopes of hills facing towards 
the N.W. 
Berwickshire. 
1. In Ay ton parish, on Whitfield farm, 2 or 3 miles N.E. of the 
village, several small boulders of grey granite occur, about 270 feet 
above the sea. Nearest rock of same kind is on Cockburn 
Law, about 10 miles to W.N.W. Near Ay ton Castle a bed of 
sand was excavated to the depth of about 20 feet and removed. 
Bits of coal (including cannel) were found in the bed, about 200 feet 
above the sea. Nearest place where coal strata occur, is in Mid- 
Lothian, on north side of Lammermuir Hills, about 30 miles to 
N.W. 
2. In Coldingliam parish, on Crosslaw farm, well rounded masses 
of hematite were turned up by the plough at a height of about 500 
feet above the sea. Nearest place where hematite has been found is 
in East Lothian, about 30 miles to N.W. But the range of 
Lammermuir Hills intervenes. On this same farm, a boulder of 
white coal sandstone occurs, which must have come from East 
Lothian. Lumps of coal have also been found there in the boulder 
clay on Blackhill farm. 
“ On the heights east of Coldingham Loch, the rocks lie in sepa- 
rate and parallel ridges. The ridges are much rubbed and planed, 
especially on the N.W. exposures, as if some mighty force had 
battered and grated them down. There were also indications of 
striae, which bore by compass nearly north, or N.J-W. — in this 
agreeing exactly with the striae at St Abb’s Head and the Fame 
Islands.” — [Address by Jas. Scott Hobson, President of Berwickshire 
Nat. Club, vol. vii. p. 175.) 
3. In Chirnside parish, at Old Castles, there are numerous 
boulders of grey granite, from 1 to 2 tons in weight, and about 300 
feet above the sea. Nearest rock of same kind is at Stanchal and 
Cockburn Law hills, visible from Old Castles, and about 8 miles 
distant to N.W. 
4. At Blackadder, in Edrom parish, a boulder of blue whin or 
greenstone is on a knoll of gravel, on the west side of knoll. Its
