LOWER BAGSHOT BED?. 103 



Very thinly laminated white and yellow sand 



White sand and blue clay, becoming more clayey towards 



the lower part. 

 [On London Clay.] 



At the eastern end of the Island the Baorshot Beds present a 

 different aspect. The mass of white pipeclay has there disappeared, 

 and the beds have either thinned from 600 feet to about 100 feet, 

 or the upper portion has become somewhat marine and is inseparable 

 from the Bracklesham Beds^. 



The junction between the London Clay and the Bagshot Beds 

 is clearly shown in Whitecliff Bay, the former being represented 

 there by ferruginous brown clay, and the latter by pale grey sands 

 weatliering nearly white and containing occasional thin laminge of 

 pipeclay. Thirty-seven feet of these sands, clays, and pipeclays 

 intervene between the upper part of the London Clay, and a band 

 of sandstone that runs out to sea at the base of the yellow 

 micaceous sands which constitute tlie greater proportion of the 

 Lower Bagshot series there. Above them there is an 18-inch band 

 of flint pebbles, taken by Mr. Fisher as the base of the Bracklesham 

 Series, for in the clay immediately above marine shells occur. 



The inland sections are of little interest, none of them beino- 

 fossiliferous or showing satisfactorily their relation to the over or 

 underlying deposits. Commencing at the west end of the Island, 

 we find the sands well exposed in pits around Freshwater, especially 

 in one close to Easton, and another on the opposite side of the 

 marsh near some new houses. At the latter there are seams of 

 pipeclay. The road cutting south of Farringford House also 

 shows a ffood section of ferruginous sand. 



Continuing eastward, we learn that pipeclay was formerly duo* 

 in a piece of rough ground half a mile east-south-east of East 

 Afton. Due north of this old pit sandy white clay is again seen 

 in the deep channel cut by a small stream north of the high road. 

 This is probably a higher seam — perhaps in the Bracklesham or 

 Barton Series. 



About a quarter of a mile east of Chessel a pit has been duo- in 

 sand with the bedding vertical. Between this pit and the London 

 Clay a number of flint pebbles are ploughed up in the field, but it 

 is not at all clear from what bed they are derived, though they seem 

 to occur low down in the Bagshot Series, possibly at its base. 



Continuing along the high road, we come to a deep cutting in 

 sand with seams of pipe clay between the two entrance lodges 

 belonging to Westover. Similar beds occur in the road to 

 Shalfleet, about a quarter of a mile north of Cal bourne. Higher 

 beds are exposed in a small pit half a rnile north-east of Calbourne, 

 where sand with a dip of 40° is overlain by a bed of pebbles, and 

 that again by clay. Probably this pebbly bed marks the base 

 of the Bracklesham Beds. A few chains further north there are 

 a number of old sand pits close to Five Houses. These were
