At Heaton Mersey the following section was met witli : 



Feet. 



Trias 45 



Permian — Red and variegated marls containing 



limestones 1S9 



Lower new red sandstone grooved. . 402 



576 



The Permian beds were cut off by a fault near the railway 

 station at Heaton Norris, first shown to me by Mr. Hull, 

 B.A., F.G.S., of the Geological Survey, which brought in the 

 Trias. This rock occupied the district between that town 

 and Goyt's Hall, in the Marple valley, where the lower part 

 of the middle coal measures was seen in nearly a vertical 

 position. 



The Author considered that Mr. Howard's sand delf is a 

 likely place for ascertaining the existence of a coal field under 

 the town of Stockport worth working. 



The next was a section made by Mr. John Wood, at Med- 

 lock Vale, between Waterhouses, near Ashton-under-Lyne, 

 and Manchester. It was as follows : 



Feet In. 



Drift 26 



Trias 2S 



Permian — Red marls, with beds of lime- 

 stone and five beds of gypsum 246 S 

 Lower new red sandstone .... 375 11 

 Coal measures about 90 



761 2 



What these coal measures were, whether above or under 

 the Bradford Four Feet Mine, it was at present impossible to 

 say ; but it was to be hoped that some mine would be met 

 with to enable us to determine the value of the great tract of 

 coal measures lying between Ashton-under-Lyne, Oldham,
