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
