HUGHES : IXGLEBOROUGH. 
full of fossils, Syringopora and LitJiostrotion being especially 
conspicuous ; close by there is a close-grained limestone — 
black marble in fact — weathering white. Below this there is 
more black limestone with shale in it, and a bed of shale at its 
base separating it from the grey limestone of the Great Scar. 
In this section we seem to have the same sequence as that 
described above, in the stream below the Shooting Box, only 
here we see the subordinate shales which were there only a 
matter of inference or conjecture. Here, where we find the 
sequence of beds from the grey limestone of the Lower 
Scar to the Black Marble Series well exposed, no fewer 
than five beds of intercalated shale can be detected, which 
fully justifies the suggestions made above in respect of the 
section seen below Farrer's Shooting Box, namely that the 
Upper or Black Marble Series was separated by shale from the 
Lower or Black Shaley Limestone Series, and this again by 
another shale from the grey beds in the top of the Great Scar. 
The great mass of drift gathered in the embayed slopes 
of South-house Moor has collected the drainage from the steep 
slopes as far south as Borrins Moor, and now^ empties it into 
Alum Pot, while Whitagreen Spring and Long Churn Spring 
drain the slopes further north and feed the swallow holes which 
now catch much of the water that must once have plunged into 
Alum Pot. Many a beautiful cave and many a yawning chasm 
tell of the changes that have taken place in the drainage of this 
hill-side as the drift and shale were being cut back. The black 
limestones can be traced north, by swallow holes and small 
exposures of limestone and shale in tlie streams that feed them, 
here and there up to Gauber High Pasture, where there are many 
sections through different parts of the series, the streams fre- 
quently entering the limestone through a bed of shale, which 
must have fallen in over broken-down caves. The nortlierly 
dip affects the denudation, and, of course, from its making the 
beds extend over a greater horizontal distance, gives the im- 
pression tliat the series is thicker than it really is. Xear High 
Barn there is a dark grey limestone with chert, and below it 
shale, well seen in the wood at the spring head above Colt Park, 
which is called from this Shiver Plantation, "shiver" being a
