Greenhow Limestone, thickness not known. 
This section was given to ns as representative of the measures 
met with in the workings of the Greenhow Hill Lead Mines. Perhaps 
the best section of these measures is to be seen in Cock Hill Level. 
I examined both this level and also the California level under Grim- 
with Fell, and found great similarity in the grit beds of the two 
levels ; but the limestone shales have almost vanished in Cock Hill, 
being only eight feet thick. 
The thin limestone which lies a little above the top of the 
Underset Grits reminds one of the little limestone met with just 
above the Grassington Grits in the shaft in Gateup. There can be 
no doubt that the Underset Grits of Cock Hill correspond in part, if 
not altogether, to the Grassington Grits. The coal too is certainly 
the same as one of those met with in the mines on Grassington 
Moor. I will now point out the position and run of the chief beds. 
The three beds of Kinder Scout Grit, lettered «, b, c, in the 
above list, run along the northern edge of the one-inch ordnance 
map, 92° S.E., with a northerly dip ; but between Beainsley and 
Blubberhouse Moor, the top turns, owing to the Beamsley anticlinal, 
and runs north-east, so that the three beds occupy the Washburn 
Valley from Moyington House to the dams a mile above Blubber- 
houses. A dirty coal, eight inches thick, was seen near the top of a, 
at the head of the Deep Gill, along which the Kex Gill or Skipton 
Road runs, about two miles west of Blubberhouses. Thence the top 
runs north of Kex Gill Road, and bending round runs north by 
Rocking Hall to the Washburn above Hoodstorth and east of Pock- 
stones ; thence up the valley and across Kitty White's Allotment to 
the Craven Fault. A thin bed of sandstone overlies it on Kitty
