Whether beds 16 to 26 are in their proper place is open to doubt. 

 They contain fossils (excepting corals) similar to those found in the 

 railway cutting at Ashford Bridge, barely a mile distant, and the clay 

 courses are alike. Many authors report the slate to underlie the carbo- 

 naceous clays and coi-al bed in the Ashford Bridge cutting. The Stocky 

 Bank is much faulted. 



In the open section at Reed Hill, as described by Mr. H. B. Woodward, 

 the slate is covered by 5 feet of marls with Modiola gibbosa, Rhynchonella 

 concinna, and Ostrea Sowerbyi. In the Stocky Bank section, in the near 

 shafts, and in other open workings, the succession of strata is the same. 



In order to consider more fully the true position of the beds 16 to 26 

 and to study relative sections and their fossil contents, your Committee 

 would defer the final report until 1896.
