Yol. 68.] MIDLAND COAL MEASTJEES AND PEEMIAN". 683 



With regard to the hoandarj'-faults, the western fault near Max- 

 stoke brings the Corley Conglomerates which dip eastwards at 15° 

 against nearly horizontal Keuper Marls. He thought that the 

 importance of the western boundary-fault near J^ uneaten had been 

 much exaggerated. 



In reply to the point raised by the President, Mr. Yernon said 

 that, although the subdivisions of the Upper Coal Measures arc 

 conformable, near Polesworth the jSTuneaton Clays are locally 

 absent, and so the nearlj^ horizontal Haunchwood Sandstones come 

 to rest upon Middle Coal Measures which have a westerly dip. 



Mr. Haedakek stated that the footprints and plants described 

 in his paper had been obtained from one quarry only, and that was 

 in the Permian rocks of Hamstead. 



Nothing is known as to the line of separation between the Upper 

 Carboniferous and the Permian rocks in the Hamstead area. An 

 unconformity accompanied by a bed of conglomerate occurs in the 

 shaft at Hamstead Colliery at a depth of 802 feet ; but this cannot 

 be taken as the boundary between Carboniferous and Permian, for 

 the Carboniferous plant Odontojjteris lindleyana occurs at a depth 

 of 729 feet, or 73 feet above the conglomerate. Above this there 

 is strict conformity, and yet at the surface true Lower Permian 

 rocks are found. Perhaps, under the circumstances, the best line 

 of separation would be at the base of the Calcareous Conglomerate 

 of Mr.Wickham TCing.
