which may he correlated with the Hardrow Sandstone, is interest- 
ing as being the first important arenaceous deposit in the Carbonif- 
erous rocks of this area. Though not clearly seen anywhere except 
in the above-mentioned sections, it can be traced around the 
remaining part of Tngleborough by the feature to which it generally 
gives rise and by the underlying and overlying limestones. 
The next limestone in ascendmg order is that which Phillips 
calls the Simonside Limestone (by later writers written Simon- 
stone). It is well defined along the east and north of Ingle- 
borough, and it may be convenient to begin again in the stream 
by Farrer's Shooting Box. 
It is seen in the next stream, where there is a swallow hole 
in it 100 yards north and about the same distance west-north- 
west of the old Sandstone Quarrj'. It can be braced by swallow 
holes about 300 yards to the north, when it is again exposed in 
Fell Close Sike, beyond which it crops out at frequent intervals 
all along the breast of the hill, by Borrins Moor to the Sheep- 
fold west of the " Stepping Stone " in South House Moor Beck. 
It is not exposed again until we reach Old Field Spring, where 
it is seen with a small dip in a north- north -east direction, about 
100 yards north of which it crops out from under a bed of shale 
on Park Fell. But the clearest section is that exposed in Shiver 
Spring, where shale is seen resting on 24 feet of limestone, and 
that on the Hardrow Sandstone. It further crops oat at inter- 
vals, frequently with shale above it, all round the north end of 
the hill as far as Keld Bank. It is seen in a swallow hole above 
the Keld, just below the 1,600 feet contour, and the dark grey 
crystalline limestone occurring at about tlie same level in the 
stream course above Mere Gill must be referred to it. Beyond 
this it is nowhere seen. Above the Simonside Limestone there 
is a thick bed of shale with subordinate sandstone. It is ex- 
posed in FeU Close Sike, and one of the subordinate sandstones 
crops out about 300 yards further north. Round the north end 
of the hill its relation to the limestone above and to that below 
is clearly seen ; in the stream w^est-south-west of Bent Hill Bigg 
Barn, for instance, there is a sandy shale on calcareous sandy 
shale, on shale with bands of sandstone and concretions, and 
it is exposed also south-west of High Barn and south of Keld
