FOX-STRAXGWAYS : FILEY BAY AND BRIGG.

town is built, are composed of Boulder Clay and other glacial beds. 
The Jurassic rocks upon which these rest are not seen in this part 
of the bay, and probably lie at some little distance below the level 
of the water. Patches of Lias clay, however, have been found on 
the shore a short distance south of the tow^n, which were at one 
time supposed to be in situ; but there is no doubt that they are 
large drifted masses which have been forced here by the action 
of the ice. 
This view helps to give some idea of the graceful curve formed 
by the bay as it sweeps round towards Speeton Gap and the Chalk 
cliffs of Flamborough, distant between four and five miles, which 
were so well illustrated by the series of photographs taken by 
Mr. Godfrey Bingley, and described by Mr. Lamplugh in his 
interesting account published in last year's Proceedings. 
The low cliffs seen in the picture are constantly being under- 
mined and washed away. This seems to be chiefly effected by land 
springs and other atmospheric causes ; by which means the whole 
cliff is gradually set in motion, and slides down to be carried away 
by each succeeding tide. The destruction caused by this means 
is enormous, and taxes the full capacity of the engineer to combat 
its action. 
2. The Southern Side of the Carr Naze and Brigg. 
This shows the cliff on the southern side of the Carr Naze 
facing the bay, with the Brigg showing hazily in the distance 
towards the top right-hand corner. Owing to this view being taken 
nearly along the strike of the promontory it is much foreshortened, 
and the picture does not convey an idea of the length of the 
remarkable reef, which extends about half a mile beyond the 
extremity of these cliffs ; these latter extend 700 yds. from the angle 
of the bay shown in the foreground, consequently the whole length 
of this headland is about a mile ; while its breadth at the top of the 
cliff, in some places, is not more than a few yards. The cliffs show^n 
in the picture are mainly composed of stiff Purple Boulder Clay with 
a few feet of Oolite rocks forming the narrow band at their base, 
which spread out on the foreshore in a succession of irregular layers.
