the fault probably crosses the Weever, passing between Weston and 
Rocksavage, and to the east of Higher Runcorn, between that range 
and Lower Runcorn. Here it appears to join a line of dislocation 
passing along the northern side of Delamere. It is evident from the 
contour of the country that a dislocation does exist there, but the 
drift here also shuts out all certamty. Near Lower Runcorn-ferry 
there is an anticlinal fault, the rocks dippmg W. by N. and E. 
by S. The beds of waterstone at Rocksavage above-mentioned 
dip gently W. by N. To the east of Frodsham Bridge they dip 
easterly 80°. To the north of Frodsham the anticlinal is seen in the 
Bunter sandstei crossmg the road. ‘The westerly dips at Five 
Crosses and Finney Hill have been already mentioned, and along the 
escarpment of high ground to the south-east of those places ranging 
near Norley it is probable that this anticlinal fault extends, being 
the line to which the waterstones of the Lower Weever will rise. To 
the north of the Weever, on the west side of the Peckforton fault, 
about two miles to the north of the pot near Budworth where the 
land is sinking, the waterstone beds (or stone marl) are seen near 
the mill at Arley on the east of the park, and are also met with near 
the south-westerly angle of the park: they are there horizontal. 
These beds are again met with cropping out along the ridge from 
Hoo-green by High Legh to Grappenhall, and overlying the Bunter 
sandstein from Agden to the west of Lymm. Between these places 
the traces of the Cheirotherium are found in great abundance. The 
dip is there about 4° southerly. 
The fault rangmg to the north-east of Lymm, between that place 
and Warburton, has been already mentioned. These beds appear to 
be cut off on the south-west by a fault extending from Northwich 
east of Stretton, then passmg down a valley to the east of Hill Cliff, 
and thence proceeding by the east of Warrigton, where it passes 
into the South Lancashire coal-field. 
On the west of this line are the Bellefield beds. These last are 
Bunter sandstei capped with an outlier of waterstone, and dip a 
little south of east. 'To the south-west of Bellefield the beds have 
been thrown down to the west upwards of 160 feet, as the waterstone 
is again met with dipping south-easterly in the valley at the foot of 
Hill Cliff. This throw is apparently the continuation of that before 
mentioned as running between Winsford and Middlewich, and to the 
south of Northwich. The Bunter sandstein is seen crossing the 
Mersey near Wilderspool Brewery. ‘The waterstones again appear 
_ for a short distance to the south-west, dippmg in an easterly and 
south-easterly direction, and overlying the Bunter sandstein-of Dars- 
bury. They are then agam thrown down to the west, appearing on 
the Preston Brook range dipping south-easterly. The Bunter sand- 
stein crops out from under them near Norton-town, dipping in the 
same direction ; thence it extends to Halton Castle, where conglome- 
rate beds occur. Here the Bunter sandstein beds again are thrown 
down to the west and continue to Lower Runcorn, where, as before 
mentioned, they are crossed by a fault near the Ferry. 
These last-mentioned beds of Bunter sandstein do not extend to
