Here we find it difficult to mark any real plane of separation 
between the Upper and Lower divisions, for we might well take 
it immediately above the remarkably false-bedded oolitic freestone. 
A section at this locality, differing in the record of the thickness 
and character of the upper beds, was described by Prof. Hull 
(Fig. 87), who marked the junction of the Upper and Lower 
"Zones" of the Great Oolite as noted above.* This junction 
probably corresponds with that which I have taken in the section 
at Milton (p. 307). Prof. Hull observes that the lowest beds of 
the Great Oolite at Swinbrook, consist of " Yellow sandy oolite, 
full of oblique lamination, and splitting into slabs;" and these 
rest on the Clypeus Grit of the Inferior Oolite, f 
The Freestone near the base of the Great Oolite, has been 
extensively worked on Taynton (or Tainton) Down, about a mile 
N.N.W. of the village, and half a mile west of the second mile- 
stone on the Burford and Stow road. The stone has attained a 
considerable reputation. Numerous old pits are to be found, like 
the <( hills and hollows " of other famous stone-districts, and these 
are now obscured by talus or overgrown by the plantations. The 
Btone indeed is now but little quarried, and in 1887 the refuse 
only was being worked in places. In the openings which I saw 
the stone was exposed to depths of from 5 to 12 feet. Jt some- 
times "pitches" at high angles of from 10 to 40 as in the 
section at Swinbrook, and this, though mainly the result of false- 
bedding, is perhaps partly due to disturbance, for the beds (so 
far as could be determined) lie very irregularly, and they are 
shattered and probably faulted in places. Further remarks on 
the Taynton Stone will be given in the Chapter on Economic 
Products (p. 479).
