FOX-STRANGWAYS : FILEY BAY AND BRIGG. 
The Boulder Clay here is remarkably hard and firm, so that 
it frequently forms vertical or overhanging cliffs. The effect of 
pluvial denudation is also very marked, the whole face of the cliff 
being ridged and furrowed in a most striking manner ; this is well 
shown in the view, but perhaps rather more distinctly in the large 
photograph issued by the Society in April, 1895. 
At the base of this great mass of Boulder Clay there are 
exposed a few feet of Oolitic rocks, which are the attenuated 
representative of the thick beds of limestone and grits so well 
shown inland along the northern margin of the Vale of Pickering. 
3. The Western End of the same Cliffs. 
AVe have here another view of these same cliffs seen from the 
shore, in the angle formed between the promontory and the bay. 
The effects of pluvial denudation in modelling the surface of the 
clay is here clearly shown ; while the vertical faces of portions of 
the cliff, with boulders and large pebbles projecting from its surface, 
testify to its toughness and homogeneous character. Another curious 
feature are the sharp points that surmount the different ridges ; 
these are usually capped by a small stone or pebble that for a time 
arrests the denudation. 
On the left of the picture may be noticed a mass of clay that 
has broken off from the cliff behind it, and which before long will 
be carried away by the action of the waves. It is in this manner 
that the vertical faces of the clay are formed, and the more rapid 
wasting of the cliff takes place. Further in the bay to the south of 
this, where there are no protecting rocks at the base, the clay is 
constantly slipping down to the level of the water, and large portions 
are removed by every high tide. Consequently we see that it is 
this narrow band of rock at the base which has enabled these clays 
to withstand the action of the sea, and to form the remarkable 
projection of the Carr Naze. 
These rocks are a portion of the Middle Calcareous Grit which 
forms the Brigg itself, while fragments of the Upper Limestone may 
be seen here and there beneath the clay. The strong southerly dip 
shown in the picture is continued across the promontory ; so that
