SUCCESSION IN THE TRENT BASIN".

Near Radcliff, on the Bingham road, there was some years ago 

 an excellent section exposing a highly contorted bed of sandstone in 

 the Keuper. The upper sandy clay and sandstone (fig. 5) had been

removed by the pitmen from a considerable tract, leaving exposed 

 a ridged and furrovt^ed surface indicating roughly a flow from about 

 the west. 



Similar deposits may be seen at many points in the Soar valley 

 and its tributaries. 



South of Kegworth Station and east of the highroad there is a 

 section showing gravel with flints contorted to a depth of 4 feet 

 into the marl. 



South of West Leake, at Gorse Cover, and in clay-pits at Hum- 

 berston, Barkby, Rearsby, Thurmaston, Barrow, &c., there are similar 

 exposures. 



Boulders of Charnwood rock are scattered over the Keuper rocks 

 to the north of the Charnwood Hills, and at one point the railway 

 passes through a cutting in a moraine evidently formed by local 

 Charnwood glaciers moving in a northerly direction. The section 

 referred to is to the east of Thringston. Here it is a Boulder-clay, 

 consisting of angular or rounded masses of Palaeozoic rock from the 

 south, stuck at all angles in a matrix of Keuper marl. The moraine 

 is about 12 feet thick, and contains here and there little nests or 

 beds of sand or pebbles with an occasional flint : otherwise it shows 

 no trace of aqueous action. 



Discussion. 



The President said that glacial sections in Eastern and Western 

 Britain had been much discussed, and consequently Mr. Deeley's
