to the coast from a point north-west of the farm-buildings of West. 
(See Fig. 45.) Forming the higher ground here, and exposed in 
three scarps at successively lower levels along the borders of the 
ravine, there may be seen a series of blue flaggy compact and 
crystalline limestones, more or less conglomeratic or brecciated, 
and containing angular fragments of Carboniferous Limestone 
and chert. Some of the beds indeed are not unlike Carboniferous 
Limestone in texture,* and intercalated with them are thin shaly 
beds. The sequence in these upper beds is not sufficiently clear 
for detailed measurements, and it is quite possible there may be 
some repetition by faults. It is, however, probable that \ve have 
here a thickness of 70 or 80 feet (if not more) of conglomeratic 
Lias above the Sutton Beds ; a view that coincides with the 
evidence obtained elsewhere along the coast, that the conglomeratic 
series thickens towards the west, and this agrees with the 
observations of Charles Moore. f 
The lowest beds seen here in the coast-section, merge down- 
wards into the white Sutton-stone Series, as seen in the following 
section of the cliff east of the Pant-y-Slade ravine :

It may be questioned whether the top 6 feet of strata, here 
included with the Sutton Series, should be so grouped ; the 
evidence obtained at Witches Point favours the view adopted, but 
the question is of no importance. We have, however, near 
Sutton, a thickness of from 25 to 40 feet of strata that may be 
assigned to the Sutton Series, for their thickness increases east- 
wards in places according to the irregularities on the surface of 
the Carboniferous Limestone. There can be no question of the 
intimate connection between the Sutton and Southerndown Series ; 
and the higher beds of blue conglomeratic limestone seen here, 
are similar to those seen above the white Sutton Beds on the 
southern side of Witches Point, where the thickness of the 
Southerndown Series is much reduced. 
The higher beds in the Pant-y-Slade ravine have not proved to 
be fossiliferous, so that we are not in a position to state whether 
the greater thickness of the conglomeratic beds is due solely to an
