LOWER LIAS : KELNTON MANDEFIELD.

bands of blue lias resemble the Sun bed or Jew stone* that occurs 
on the top of the White Lias. 
The stone-beds are mainly confined to the area of the river 
Yeo, and west of the Fosse Way. Numerous quarries indicate 
their presence in the outliers north of Langport, near Long 
Sutton, Somerton, Kingsdon, Charlton Axlam, King Weston, 
and Keintou Mandefield.f Among the more important are the 
quarries at Highbrooks, between Long Sutton and Kingsdon, and 
those at King Weston. There we find even-bedded and persistent 
bands of limestone (4 or 5 inches thick) and clays. Slabs of stone 
6 x 10 feet in size are obtained, for paving-purposes ; blocks are 
shaped for building-material ; and some beds are used for road- 
metal. Perhaps the best sections are exposed near Keinton 
Mandefield, and the following account of the Stipstone quarry 
(named after the field in which it is situated) gives the names 
in local use : FT. IN.

The "Thin Corner" and beds below, are all used for making lime for building 
and agricultural purposes. Many of the limestones are used for building- 
purposes, and some for troughs, steps, &c. The beds are often spoken of as 
" sizes," and they lie very close together with but thin partings of shale. 
Immediately north of Queen Camel, a fault has upraised the 
White Lias, together with the overlying limestones of the Lower
