LAMPLUGH : CHALK OF FLAMBRO' HEAD.

lington, flints are seen for the first time on the southern side of 
the Head, just where the cliffs begin to be so cave-worn and 
fissured, in a recess known as High Stacks. They are here present 
on the scar nearly to the base of the cliff ; but the chalk has a pretty 
constant rise northward, and they soon rise in the cliff foot, and 
by the time we have gained the point where the sea alway3 
washes the base of the cliff, and thus bars further advance, which 
is only a few hundred yards further north, the chalk contains flints 
nearly to the top of the cliff, which is here about 90 ft. in height 
(excluding the drifts). 
Further advance in this direction being thus impossible, it is 
necessary to ascend, and to go on to Selwicks Bay before one 
can again descend in safety. Upon examining the south side of 
this bay, the cliff is again seen to have flints from top to 
bottom, occuring in irregular patches which form inconstant layers. 
Thence, they may be traced to the centre of the bay, where the 
beds become suddenly contorted and shattered, and dip down 
steeply at a constantly increasing angle until they are almost 
vertical. Here all the interstices of the shaken chalk are filled 
with veins of calc-spar. 
In the cliff, the actual fault is concealed by a great mass of 
slipped drift, which has come down to the beach from above, over 
which a little stream winds its way, and this has no doubt caused 
the fault to be overlooked. On the beach, however, the actual 
line of fault, though somewhat obscured by the plenteous growth 
of tangled sea- weed, can be distinctly traced at low water. 
On examining the evenly-bedded chalk on the north side of 
the slip, the existence of the fault is immediately proved ; for 
there are no flints whatever in the cliff. Neither do they reappear 
until we reach the grand group of arches and passages, which, 
projecting seaward, form the northern side of Selwicks, where a 
few flints may be seen on their rocky pavement, under circum- 
stance^ resembling those under which they first appear at High 
Stacks, viz. : — For a short distance they occur sparingly, but soon
