the lower beds in succession. There are a few dislocations 

 and faults, and in some parts the limestones are thrown into 

 wave-like ridges and hollows ; but the contortions are not so 

 remarkable as at Howick, Holy Island, and Scremerston. 

 As the greater proportion of the middle group of the moun- 

 tain limestone rocks is seen here, the following section will be 

 instructive, giving, as it does, the strata in detail from the 

 highest at Ebbs Nook, down to the lowest which have been 

 reached by pit sinkings in the neighbourhood. It has been 

 made out by repeated examinations of the coast, collated with 

 information derived from pit sinkings, which has been kindly 

 supplied to me by my friend, Mr. William Wilson, the in- 

 telligent manager of the Shilbottle Colliery. The lower 

 strata from number 68 downward are taken entirely from pit 

 sections.
