Vol. 57.] OF THE NORTH COTTBSWOLDS. 135 



There are obviously strata (and farther south-east too, which is 

 important) higher than Upper Freestone, yet which show no capping 

 of Upper Trigonia-giit. That indicates that the freestone seen near 

 Campden Hill Farm which is capped by Upper Trigonia-grit, must 

 be later than Upper Freestone. In the margin of the following 

 section I have placed the possible interpretation of the beds, though 

 confessing that their exact position in the sequence requires more 

 investigation : — 



Section IX, — Upton Wold Farm, Blockley. (North of the 

 Farm, 3 furlongs.) 



Ft. 

 Harford X. 1. Disturbed stone, like Ihe bed below, more or less 



Sands (?) mixed with soil 2^ 



2. Grey stone, with partings of whitish -yellow sands, 

 some partings 1^ feet thick 13 



Note. — Bed X 2 may be a local condition of Upper Freestone ; but if Harford 

 Sands, it indicates a very great thickening of the deposit. It may be compared 

 with Bed XI 2 of Section IV, p. 133. 



Farther south-east there is evidence, at Bourton Clump, that the 

 Upper Trigonia-gTit, though well separated from the Upper Freestone, 

 does lie not far above the Snowshill Clay. There seems to be some 

 irregularity about it, but it is probably not great ; and the evidence 

 points to Bajocian denudation having removed all from the Not- 

 grove Freestone to the Lower Trigonia-grit, inclusive. This brings 

 the section into line with the exposure in the cutting by Aston 

 Farm, on the Banbury & Cheltenham Railway, where the Upper 

 Trigonia-grit is separated from the Harford Sands by 4 feet of a 

 kind of freestone. In the Bourton-Clump section it is separated 

 by 7 feet of rock, but there may be a few feet more. The following 

 is the section : — 



Section X. — Bourton Clump.

 Upper Tri- I. ' Top beds,' with Rhynchonella angu- 



gonia-grit. lata, Terehratula glohata, etc.,

 thrust.

oysters 2

Note. — Bed XI. 1 may be the same as Bed X. 1 in Section IX, and then the 

 Upton-Wold section would be a continuation of this one.
