HUGHES : INGLEBOROUGH. 
Nothing more is seen until we get up to the Shooting Box, 
where a spring below and swaUow holes above indicate the 
presence of the Hardrow Limestone at no great depth. 
This is suceeded by an even-bedded sandstone in which, 
some 100 yards to the north, a quarry has been opened to pro- 
cure stones for walling. About 500 yards further, in Fell Close 
Sike, a black limestone is exposed, which must be referred to 
the Hardrow beds, but beyond this its position is a matter of 
inference from springs and other small indications, until we 
come to South House Moor Beck, where, about 60 to 65 feet 
above the highest beds of the Black Marble Series, there are so 
many fragments of black limestone as to suggest that the Hardrow 
Limestone is not far off. If it has not thinned out consider- 
ably, at any ra.te it does not make much mark on the ground 
all round the north end of tlie hill. A spring here and there, 
at about the right level, has been taken to mark its lower bound- 
ary, and, if it turns round the hiLL with the other formations west of 
High Barn, it must be taken below the sandstone by which, when- 
ever the sequence is clearly seen, it is always succeeded in ascending 
section. Nothing more can be made out clearly about the Hard- 
row Limestone. The steepness of the hillside and the thickness 
of the drift plastered on to it have obscured the rest of its outcrop. 
The Hardrow Limestone is succeeded in ascending section 
by a mass of sandstone, sometimes more, sometimes less flaggy 
and split up by subordinate shales. It carmot be less than 
100 feet in thickness and often gives rise to a considerable feature, 
helping by its prominence and heavy talus to obscure the under- 
lying limestone. It is seen in a quarry about 100 j^ards north 
of Farrer's Shooting Box, and again in Fell Close Sike, and is 
represented by a hard quartzose rock, dipping at a small angle 
to the north, in a quarry adjoining Fell Close Sike. The flaggy 
sandstone seen about 300 yards further on, a little west of 
north, on Fell Close, seems to be a lower part of the same 
bed. It is seen with limestone resting on it in Shiver Spring, 
which runs down by Bent Hill Bigg Barn. 
About 250 yards west of High Barn, on the boundary line 
at the north end of the hill, an upper and a lower sandstone 
are seen, separated by a considerable mass of shale. This series.
