Contortions in Mica Slate : Whately. 



Contortions in Mica Slate : Conway. 



The following- extracts from my travelling notes, will show the dip 

 and direction in numerous places of the strata of the different ranges 

 of mica slate that have been described. It has already been men- 

 tioned that this rock, in connection with the limestone of Berkshire 

 county, has a direction north and south, and a dip from 15° to 30° 

 east, often greater. Between Cheshire and Lanesborough, for in- 

 stance, its strata dip from 60° to 90° east ; and between Lanesborough 

 and Hancock, from 30° to 40° east.
