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



upper new red sandstone, and no attempt, that I am aware of, 

 has ever been made to follow them under it. 



This section also appears to shew that the trias and per- 

 mian beds are sometimes unconformable to each other, or 

 some of the latter would have been seen in it.

This is seen on the banks of the river Tame, about three 

 miles north-east of Stockport. The upper new red sandstone 

 was proved near Reddish Mills, by the late Mr. Becker, in a 

 bore made on his estate to be above 100 yards in thickness, 

 and it runs up the valley to near Arden Hall. Its dip is to 

 the west, at a moderate angle. What beds occur immediately 

 under it cannot be seen owing to the thick covering of drift ; 

 but, most pr<5bably, permian marls similar to those at Heaton 

 Mersey, exist there, as a red sandstone is found on the rise in 

 the field below Beet Bank Bridge, having the soft crumbling 

 consistency, of the same colour, and exhibiting all the false 

 bedding so characteristic of the lower new red sandstone of 

 Collyhurst. Like the last-named deposit, this bed has also 

 been used for moulding purposes. It lies unconformably on 

 the coal-measures of the middle part of the field, which are 

 seen in the river under the bridge, dipping to the west at an 

 angle of 19° Most probably the trias and permian beds here 

 lie in a trough of coal-measures, and skirt the latter on the 

 south. The late Mr. Fletcher's trustees, in working their 

 little coal, which lies to the north-west of the footpath, leading 

 from Reddish Mills to Beet Bank Bridge, Mr. Peter Higson, 

 mining engineer, informs me, drove their levels south for a
