10 PROCEEDINGS OF THE COTTESWOLD CLUB 



From it can be traced boulders from the North, 

 red chalk from Lincolnshire, the presence of Northern 

 Drift on the West of the Severn mingled with the Oolite ; 

 the Jurassic outliers which have been detached by denu- 

 dation from the main body of the formation, and the 

 widening of the valley now separating the secondary 

 formation on the East from the primary on the West. 



From the pit I made the following short address on the 

 subject : — 



There is every reason to believe that, towards the close 

 of the Phocene period, a gradual lowering of temperature 

 took place, which increased as the Glacial period set in. 



Now I will endeavour very briefly to describe what I 

 think was the aspect which the country before us then 

 presented to the eye. 



The Cotteswolds formed a higher range of hills than 

 now, and extended far into the valley, to the then slopes 

 of the Malverns ; the latter range probably coming some- 

 what further eastward. 



The evidence of the Cotteswold extension is shewn in 



the numerous outliers of Oolite in the Lias valley, as seen 



at Bredon, Oxenton, Robin's Wood Hill, Meon ; and those 



rather lower outliers of Alderton and Churchdown, which 



are capped with Upper Lias, the Oolite having been 



denuded. The connection with the table-land of the 



Cotteswolds is evident from a comparison of the heights : 



Bredon ----- 975 feet 



Leckhampton - - - - 978 ,, 



Birdhp - - - - - 955 „ 



Painswick Beacon - - - 929 ,, 



I am disposed to think the Severn, which you will 

 observe on the map is considerably West of the Cottes- 

 wolds, has not materially changed its course. 



We are now to consider the Glacial period, in which 

 there is strong evidence of a great submergence. The 

 current came from the North, bringing di)wn with it
