198 ON THE REVOLUTIONS 



fine specimen of dressed rock, which had been laid open by 

 the forming of the road, and is still visible ; the direction is 

 fifteen degrees south of west. 



North Berwick Law in East Lothian, has a tail extending 

 towards the east ; it has likewise a specimen of whinstone rock 

 with the dressing upon it. 



No. 19. Another specimen occurs on a hill, which makes one of 

 a group of rocky eminences, to the southward of North Berwick 

 Law, upon one of which the ruined tower of Fenton stands. The 

 particular spot lies three or four hundred yards to the northward 

 of that tower, and close to the eastward of the little village of 

 Kingston. The rock presents to view furrows and scratches si- 

 milar to those above described on Corstorphine Hill, with the 

 additional circumstance, that the action of the stream has here 

 undergone a visible modification, by the prominent form of 

 some parts of the rock, in consequence of which the dressings 

 have, in some places, been turned, to the amount of five or six 

 degrees, out of the general direction ; which, however, they re- 

 sume gradually, in the course of a few yards. A curvature is 

 thus produced, highly characteristic of the action of a torrent 

 from the west. The scoopings, too, meeting the general direc- 

 tion in obtuse angles, are indicated in the most striking man- 

 ner. The general direction, independently of these local dis- 

 turbances, agrees with that in the neighbourhood of Edin- 

 burgh, being from fifteen degrees south of West. 



The same law prevails in other parts of East Lothian, as ap- 

 pears by examination of the ridges at Spott and Pinkerton 

 which are very conspicuous objects from the great road be- 

 tween Edinburgh and Dunbar. 



Observing the direction so constantly maintained in all this 

 district, which, at the same time, is that of the valley in which
