548 D. MILNE HOME ON HIGH-WATER MARKS ON THE 
clay near Berwick. A block of pink Granite was picked up by me at a railway 
cutting near Burnmouth Station, 8 miles north of Berwick. I sent a bit of it 
to Mr M‘DonaLb, granite-polisher, Aberdeen, and he reported that it is a kind 
of Granite rare in Scotland, and known to him only in the form of boulders in 
Kemnay parish, situated about 10 miles N.W. of Aberdeen, though he believes 
that it must also occur in rocks not yet worked. Boulders of this pmk Granite, 
he added, have been strewed along the shore south of Aberdeen. Mr Gorpon 
of Cluny informs me, that there are rocks of this pink Granite on his estate 
N.W. of Aberdeen. 
Mr James GEIKIE, in his “ Great Ice Age,” page 225, states that he had seen 
‘“‘bits of Mica Schist in the Till at Reston, in Berwickshire.” 
4, Striated Rocks occur at the following places :— 
(1.) In the valley of the Tweed near Carham Railway Station, at the Lime 
Quarry, about 180 feet above the sea. This rock has been already referred 
to as the parent of many boulders lying to the eastward. It is a hard white 
limestone. The striated surfaces are generally horizontal. The direction of 
the striz varies between E.N.E. and E. by N. (magnetic). 
(2.) The next locality in height above the sea is at St Abb’s Head, where, 
at about 250 feet above the sea (on the igneous rock), there are striae, caused 
by an agent passing from N. by W. 
On the east side of Coldingham Loch, about one mile inland from St Abb’s 
Head, there are several well striated rock surfaces facing the N.W. There the 
direction of striee, and height above the sea, are the same as at St Abb’s Head. 
(3.) On Smailholm Craggs (situated in the west of Berwickshire), at a 
height of 570 feet above the sea, there is an extensive surface of igneous rock, 
beautifully smoothed and striated. The surface of the rock dips W.N.W. at an 
angle of 35° or 40°. The direction of striz is S.W. by W.; some striz are 18 
inches in length. An agent to produce the striz, taking into account the slope 
of the rock, probably came from W.S.W. A general examination of these craggs 
exhibited ten or eleven spots, where the rocks had been rubbed and smoothed 
on their sides facing the W.S.W., by some agent or body passing over them. 
(4.) On a part of the hill, occupied by Hume Castle, there is a surface of 
igneous rock about 742 feet above the sea, bearing strize running E. and W. 
(5.) The locality next to be mentioned is beyond the district, but it is not 
far, and it is rather important, being at the sea-level, viz., on Farne Island, 
situated about 15 miles south of Berwick, and about 8 miles from the coast. 
The direction of the striz is N. by W.—agreeing, therefore, with the St Abb’s — 
Head striee. 
5. As not unconnected with this subject, it may be mentioned that there are 
several localities where the rocks bear evidence of disturbance and. derange- 
ment by the passage over them of some agent or force of considerable power. —
