218 MR. E. W. BINNEY ON THE PERMIAN BEDS 



ing the line of the fault which bounds the Manchester coal- 

 field at Bradford and Ardwick^ through Heaton Mersey it will 

 run into and connect itself with the fault at the latter place. 



The conglomerate bed lying on the top of the lower new red 

 sandstone, although not noticed in the section, occurred here; 

 in fact, the permian beds at this place are a continuation of 

 those at Manchester, under the upper and new red sandstone, 

 and very similar to them both in character and thickness.

This is taken in a line from All Saints' Church to Water- 

 houses, in the valley of the Medlock. The whole of Chorlton- 

 on-Medlock, and the greater portion of Ardwick, rest upon 

 the upper new red sandstone, which dips to the south-west 

 at an angle of about 10°. At the surface no evidence of the 

 permian beds is to be s^en, and even at the outcrop of the 

 upper new red sandstone, a little above Pin Mill Bridge, no 

 traces of these beds are to be met with. This is, no doubt, 

 owing to the permian and overlying trias beds being uncon- 

 formable to each other, although they both dip in the same 

 direction, and at very similar angles. However, all the 

 borings for water prove the existence of the permian beds, 

 underneath the upper new red sandstone of Manchester. 



By the kindness of Mr. William Mellor, of the Ardwick 

 lime works, I am enabled to give the following section, which, 

 although a little to the south-east of the line in the wood-cut, 

 shews well the superposition of the strata under the city.
