"Additional Notes on the Lancashire Drift Deposits," 

 by E. W. BiNNEY, F.RS., F.G.S., President of the Society. 



In two previous papers, abstracts of which are printed 

 in the Proceedings for 1870 and 1871, the author has given 

 his views on the high level drift found on the hill sides, and 

 the lower level beds found between Manchester and Oldham. 

 He there shewed the difficulty of classing these deposits 

 under Professor Hull's three-fold division of Upper and 

 Lower Tills or Boulder Clays, divided by sands and gravels. 



In the present communication he took the section of the 

 railway from Liverpool to Manchester, kindly supplied to 

 him by Mr. G. B. Worthington, one of our members, running 

 nearly west and east for a distance of 80 miles, and shewed 

 the deposits in the cuttings, and journals of shaft sinkings 

 and bores ; and he then followed the Lancashire and York- 

 shire line from Miles Platting to near Todmorden, running 

 nearly north and south for a distance of 15 miles, and 

 described the deposits found in its sections, and neighbour- 

 ing pits and bores, and noticed the singular termination of 

 the drift near to the Rochdale Brick and Tile Works, at 

 Summit, above Littleborough, in the Todmorden valley. 



Commencing with the railway at Edge Hill a considerable 

 deposit of Till or Boulder Clay is found at a height of 125 

 feet above the level of the sea. Then comes the rising 

 ground of Olive Mount, composed of Trias, as exposed in 

 the cutting, and reaching a height of 186 feet, but showing 

 little traces of Till. Next succeeds a series of embankments, 

 affording only one small cutting, chiefly over and through 

 Till, up to Huyton, where the Trias is covered by that
