THE PHOTOGRAPH FOR 1882. 
THORNWICK BAY, FLAMBOEOUGH. BY G. W. LAMPLUGH. 
The Photograph for this year is an excellent view of Thornwick 
Bay, a little inlet on the northern side of Flamborough Head. 
The spectator is standing under the shadow of the cliffs on the 
west side of the " Bay," and looks due east across to the opposite 
headland. 
The height of this headland is 150 feet. As will be seen, it is 
thoroughly riddled with caves and gullies, there being no less than 
seven caverns within the limits seen in the photograph, — and two 
long deep gullies which were probably once arched caves like the 
others. They are generally excavated along master-joints. 
It is low-tide, and the beach in the foreground is strewn with 
rough blocks of chalk from the cliffs, with a thin scattering of 
darker transported masses from the boulder-clay ; all covered with 
a plenteous growth of sea-weed, except near high-water mark. The 
weed is chiefly, but by no means wholly, the common Bladder- 
wrack (Fucus vesiculosus). 
The headland shows hard flinty chalk, capped with glacial drift 
of considerable thickness. 
The Chalk contains much flint in irregular nodular layers ; 
fossils are of r ire ocoarrence, — -here and there a^ large Inoceramus 
• ( I. Cuvieri ? J, an Echinoderm crushed beyond recognition, or a small 
Terebratula. The chalk dips gently south. The darker tint of the 
rock at the base of the cliff, within reach of the waves, is due to 
weathering and organic growth, and marks the limit of high tide. 
The Drift is, as usual, complicated and variable, but the fol- 
lowing section may be made out : —
