The quantity of work done in the bore each day is given 

 for the purpose of shewing the different degrees of hardness of 

 the strata met with. As is the case with most information of 

 this kind, the men who superintend the borings give their 

 own names to the strata met with, therefore, I think it best 

 to state my opinion as to the nature of the above beds. They 

 may be classed as follow, viz.: — 



ft. in. 



Upper new red sandstone (trias) 143 4 



Red and variegated marls, with beds of limestone and 



impure ironstone (permian) 160 



Conglomerate (permian) 1 2 



Red raddle, with lenticular markings (permian) 2 7 



Lower new red sandstone (permian) 59 4

The lower new red sandstone rests unconformably on the 

 highest portion of the upper coal-measures at Ardwick, as I 

 some time since had an opportunity of satisfying myself be- 

 yond all doubt, with the assistance of Mr. Mellor, who did 

 me the favour to show me these two formations in contact, 

 during the progress of some of his mining operations. The 

 carboniferous strata, like those described by me in a similar 

 position at CoUyhurst, hereinafter noticed, presented every 

 appearance of having undergone considerable erosion by water, 

 the shaly clays shewing a very irregular surface, on which lay 

 rounded boulders of Ardwick limestone, and the hollows in
