.364 LIMESTONE-KNOLLS IN CRAVEN. [^^g« 1 899, 



Mr. Maeh, in reply, admitted that lie had overlooked the nodular 

 origin of the pebble-like forms in the rock from the stream flowing 

 into Winterburn Reservoir. If that origin were established, it 

 would not throw light on either explanation of the breccias. He 

 protested against the statement that he had only described proofs 

 of folding in a district at some distance from the knolls. He had 

 taken Draughton Quarry because it was a well-known section, but 

 similar proofs of disturbance might be found throughout the area. 

 In reply to Dr. Wheelton Hind, he observed that several of the 

 statements which that speaker had made were, he believed, equally 

 opposed to the views of Mr. Tiddeman and to the views expressed 

 in his paper. He agreed that palaeontological evidence would be 

 most satisfactory, and had tried to obtain it, but, meeting with 

 difficulties, had used lithological characters as being to some extent 

 valuable. Dr. Hind spoke of the similarity of ' the breccia ' in the 

 €raven district and in Derbyshire, but he (Mr. Marr) would point 

 jout that there were several breccias at different horizons in the 

 CIraven area.
