GREAT OOLITE : NAUNTON. 295 
Slates were worked (in 1887) about one-third of a mile 
south-west of Whitall Farm, and the following section was 
exposed : 
FT. IN. 
Brown clay with weathered fragments 
of limestone 1 6 
fFissile blue limestone - 4 
Fissile sandy limestone or calcareous 
q, fll -i sandstone ; 3 or 4 inches at base solid 
Beds ^ " Slate," the upper beds rotten - 1 8 
I Greenish-yellow marl, with shaly bands 1 
| Fetid greyish-brown sandy limestone, 
[_ with Oeirea and Gasteropods. 
The " slates " here were greyish-brown and not distinctly 
oolitic. Ostrca, Placunopsis socialis, and Trigonia impressa, 
occur on the surfaces of the slaty beds. 
The variable nature of the Stonesfield Slate Series, in this and 
other districts, is a characteristic feature for the beds become of 
economic value at somewhat different horizons here and there, 
even in the same quarry. 
At Kyneton Thorns between Condicote and Naunton, there 
were formerly many quarries, and it is recorded that at one of 
these, no less than 120,000 roofing slates were made in the course 
of a season. The stone was raised about December and spread 
over the surface of the ground, and when " weathered " (or frosted) 
the blocks were capable of being split into thin layers.* The 
following section was shown in one of the quarriest :

Among the fossils, a new species of " Asterias " or Astropecten 
cotteswoldice,^ Belemnites, Fish-remains, a tooth of Megalosaurus, 
and Plant-remains were obtained. 
Slates have been quarried over a large area north and north- 
east of Naunton. The following section at Summer Hill, Eyeford, 
to the north-east of Naunton, was recorded by Prof. Hull :
