OF THE EARTH'S SURFACE. 191 



diately above it, is a good specimen, shewing the small features 

 of the dressing ; the direction of which agrees with that of 

 the rest on this hill. This specimen lies contiguous to the 

 fence, on the south side of the field, at the distance of forty-nine 

 paces west from a wicket, close to some cottages. 



No. 15. Close to the bottom of the hill, on the south-east, 

 there is a specimen, in fine condition, near to the avenue lead- 

 ing to Belmont. As we go up this avenue, in a direction 

 nearly due north, we leave two fields upon the right hand. 

 The specimen here alluded to lies in the second or uppermost 

 of these fields ; being the same in which a whinstone quarry is 

 now worked. The specimen lies near to the south-west cor- 

 ner of that field, being forty paces distant from the wall on the 

 west, and forty also from that on the south. It presents one 

 of the most perfect and complete examples I have met with, 

 of a groove, with a set of scoopings corresponding alternately 

 to each other in opposite sides of it, and some of the obtuse 

 angled ridges in the highest perfection. The whinstone is also 

 very distinctly dressed with the small features, which lie hori- 

 zontally, and follow some wavings of the groove : their general 

 direction is like that of all the rest, with slight variations on 

 each side, of ten degrees south of north ; at the same time, it 

 is worthy of notice, that the surface of the ground declines ra- 

 pidly from north to south. 



I have thus pointed out fifteen specimens, within a circle 

 two miles in diameter, surrounding Corstorphine Hill, each 

 exhibiting both the large and the small features which in- 

 dicate the action of water flowing with violence along the 



surface,
