Feet. 



1. Bed sandstone - rock, rising up from the beach to a 



height of about 80 



2. Fragments of clay-slate and grit, partly waterworn, and 



mixed with small earthy debris of the same 4 



3. Compact, very firm, fine blackish clay, containing a few 



small stones, some of which are glacially striated ; 

 also a few crumbs of shells too small for identification. 

 There are likewise subordinate seams of brownish 

 sand in this clay 8 



4. A thin seam of waterworn pebbles of clay-slate and grit. . 0£ 



5. A thick bed of fine brownish sand about 15 



6. A bed of blackish fine clay, similar to No. 3 5 



7. A bed of fine brownish sand, in some places full of shelly 



debris 2 



8. A bed of fine blackish clay, thinning out into sand. 



Above this there were no good sections, but merely small openings 

 in places, mostly showing fine sand. No Boulder-Clay appeared. 

 The seams of clay vary much in thickness when followed laterally. 

 As a whole, the mass of this mound has the appearance of being 

 deposited in water, and may have been a portion of the sea-bed 

 during the period of submergence. Many of the shells have been 

 pierced by boring mollusks, as at King Edward. 



The King-Edward locality, however, seems to me one of more 

 especial interest, inasmuch as it appears to afford good evidence of the 

 demolition of marine strata by the subsequent action of glacier-ice ; 

 for I found there the fine dark silt containing complete specimens 

 of Tellina proximo,, passing up into a sandier seam containing a 

 greater abundance and variety of shells, among which Tellina 

 balthica was one of the most plentiful. Above this lay a heavy 

 mass of unstratified pebbly clay with ice-scratched stones, and in 

 the lower part shell-fragments. This Boulder-Clay of King Edward 

 is of a dark-grey colour, varies in depth from 9 or 10 to 30 feet 

 or more, and along the valley is covered by a mass of waterworn 

 gravel 10 to 20 feet thick. In one place I found the Boulder-Clay 

 passing down at the bottom into a bed of fine silt, with the strati- 

 fication much deranged, and containing seams of gravel, broken 

 shells, and shelly mud. The ice-scratches on the stones as they 

 lay in this Boulder- Clay seemed as a rule to point west 5° to 40° 

 north, which may afford some indication of the line along which the 

 ice moved. Here, therefore, we seem to have caught the ice in 

 the very act of smashing up the marine strata, and converting them 

 into a shelly Boulder-Clay like that of Caithness. 



At a place called Black pots, on the coast 2 miles west of Banff, 

 I examined an interesting exposure of the clay at the tile-work 

 there. The top of the section rises to about 80 or 90 feet above 

 sea-level, and the depth of material lying on the rock amounts to 

 60 or 70 feet. The greater part of the bank at the time of my visit 

 was seen to consist of a fine, very dark, blackish-blue clay of a soft 

 silty nature, which graduated laterally in the space of 20 yards 

 into fine sand at one side of the section. This sand contains some
