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



to the south west, at an angle of 25°, which gradually 

 diminishes to 16° as it approaches the coal-measures. The 

 last-named strata cannot be traced for a few feet towards the 

 north-east ; but when they are seen, they are found inclining 

 to a little north-of-west, at angles varying from 12° to 15°. 

 On proceeding further towards Atherton Mill, however, they 

 are found not to have been so much aifected by the fault, and 

 recover their regular dip to the south-west, at an angle of 16°. 

 The fault here, which has thrown up the lower new red sand- 

 stone, runs from south-east to north-west, and has no doubt 

 considerably disturbed both the carboniferous and permian 

 beds in this neighbourhood. 



The condition of the lower new red sandstone here is much 

 altered by the fault having been squeezed and apparently 

 changed by heat ; but it seems to have been originally of 

 brownish and greenish colours and coarse structure, similar to 

 the Patricroft and Norbury beds. 



Leigh Section. 



Nothing is seen of the permian beds near Leigh, except in 

 certain borings. Messrs. Barton, in some borings near the 

 Pickley Green Brook, had gone down apparently about 

 eighty yards, for the most part in red measures. 



Mr. Marsh, in a boring near his house, not far from the 

 brook which divides Leigh from West Leigh, found the 

 following strata : —
