 Fern rag on the north of it. At Emborrow the dip is easterly. 



Section 17. 



At Goodeaves pit, from the Bailiff, Mr. Jeflferies. 



The dip in general is southerly, but sometimes it becomes northerly. The 

 beds are sometimes vertical, but never continue so above 10 fathoms. The 

 line of bearing is N.E. and S.W., as it is at Newbury. Faults are fre- 

 quent which throw up the measures on the northern side.

* The callows has a mealy joint in the middle, 5 or 6 inches thick, which is covered with marl, 

 and burns to a white ash. The mealy joint is divided by a parting as thin as paper, which occurs 

 at Vobster, Bilborough, Old Goodeaves, New Ringing pit, Coal Barton, Edford Mash, and
