Alves railway-station, about G miles west of Elgin. The late 

 Dr. Gordon (of Birnie) took me to see it many years ago. The ridge 

 lies east and west, and rises to a height of 250 or 300 feet above 

 the level of the sea. The rock along the top is bare, and composed 

 of a hard, fine-grained, grey sandstone of Devonian age, which has 

 been strongly rubbed by the ice. The scratches and furrows 

 point about 10° or 15° north of west, so that the line of movement 

 crossed the ridge obliquely. Although the surface is unprotected 

 by any covering of earth or day, the markings are in many places 

 as fresh and clear as if they had been made bat a few years ago. 



That the movement came from the west-north-west is shown by 

 the transport of numerous fragments of the stone for many miles 

 to the south-east. 



On the sandstone of Quarrywood Hill, near the manse of New 

 Spynie, Dr. Gordon showed me other instances pointing west 

 15° north, and on a hill near Burghead, west 30° to 35° north. 

 The surface of the Cornstone beneath the Boulder-Clay at Links- 

 field Quarry, near Elgin, is also strongly glaciated, and even 

 polished by the ice, the scores and scratches running from north- 

 west to south-east. In one place, I found the direction almost due 

 north and south. 



Along the coast from Speymouth eastward to Praserburgh, I have 

 not met with any good display of glaciation on the rocks, butmerely 

 a few traces here and there, near Melrose Head, Crovie, Troup, 

 and Aberdour. On the cliff at Troup Head I found some markings 

 running east and west. At Kinnaird Head beside the town of 

 Eraserburgh, the indications are more decided, showing a movement 

 of ice coming from the north-west. The same direction is maintained 

 round the corner of the coast to the fishing- village of St. Colms.

The eastward movement of boulders along the southern shore of 

 the Moray Eirth has long been known to observers in that quarter. 



At Linksfield * a huge mass of Oolitic beds, 40 feet thick and 

 several hundred yards in length, has been transported bodily, and 

 lodged on the top of the iceworn surface of a Devonian limestone, 

 locally known as Cornstone, there being a layer of red Boulder- 

 Clay 1 to 4 feet thick between the two. Other large transported 

 masses of a similar nature have been found in the Elgin district 

 at Lhanbryde, Spynie, and elsewhere. 



At Plaidy, on the Turriff railway-line in Aberdeenshire, a great 

 mass of greenish-blue Oolitic clay, brought probably by ice from the 

 shores of the Moray Eirth, has been stranded on the top of the slate- 

 rocks of the district. It is so big that a tile-work has been established 

 in it, and worked for many years. It was first discovered in making
