94 T. M. BEADE ON THE DRIFT-BEDS OE THE 



Pig. 9. — Section on side of road, northern face of Helsby Hill. 



Surface of road. 



1. Hard flesh-coloured Keuper sandstone. 



2. Fine yellow laminated sand with interlaminations of reddish clayey sand, 



very regular and distinct, with a slight slope up the hill ; occasional 

 waterworn travelled pebbles occur, principally near the top. 



3. Sand blackened with iron oxide (" fox-bed"). 



4. Subaerial detritus, or " talus," from the cliffs above, witb white sand filling 



the interstices between the rubble, and large irregular blocks which were 

 freely strewn on the slope. I could find no shells. At several points 

 along this road are to be seen very large granite boulders lying in the 

 sand-drift. 



Pig. 10. — Section showing the position of the Stratified Drift in 

 relation $o the escarpment of Helsby Hills. 



a, b. Talus of angular blocks of Eed Sandstone, lying upon and covering 

 stratified yellow sand (c) containing occasional rounded drift-pebbles. 



Keuper marls. At one point there is a remarkable basin-shaped 

 sweep from the cliffs on the right bank of the river, looking very like 

 the effect of a large landslip afterwards modified by rain. There is 

 a remarkable absence of drift in this valley, which is worth noting. 

 On the plateau on each side drift can be found. About Aston 

 there is generally sand covered with sandy clay and then with 

 yellow sand : and near Aston Grange the Boulder-clay is to be seen 

 in the farmyard. Erratic boulders are also to be met with. 



Stockport.— la. April 1874 I examined and drew a section (fig. 11) 

 of the drift disclosed in the London and North-Western Kailway 

 Company's ballast-pit at Stockport. At the base was very light yellow 

 sand, 1, in all sorts of curved contortions, looking at a distance like
