Near the hummock of reddish-coloured till, on which the 

 old castle of Brough stands, the Aughill brook joins the 

 Swindells brook. In the bed of the former stream the con- 

 glomerate is seen in great thickness ; I did not measure it, 

 but I should estimate it at fall 300 feet. Under it appear 

 some red sandy beds parted by thin beds of shale, not well 

 exposed, but apparently of a soft nature, and most probably 

 the soft red sandstone of Belah Scar, and then come coarse 

 and brown-coloured girts, which are succeeded by thin lime- 

 stones. These strata, both permian and carboniferous, dip 

 to the west-south-west at an angle of 46°.
