The bed 10 I take, in the absence of evidence to the 
contrary, to be the lower part of the Lower Trigonia-grit ; and 
I should expect to find the Harford Sands immediately beneath, 
that is, if they are developed in this neighbourhood. Above 
this mass of limestone lies a thin clay-band with a quantity of 
broken shells; and it is rather remarkable to find a clay-band 
intercalated in such a deposit as the Inferior Oolite. Bed 8 
with its mollusca undoubtedly belongs to the Lower Trigonia- 
crit. The Gryphea-grit (bed 2) attains the very respectable 
thickness of twelve feet—a thickness which is unusual, and is 
only equalled by the development at Stroud Hill.* 
The bed (1) above the Gryphza-grit is most interesting. 
It is the equivalent of what I called the Notgrove Freestone 
(Op. cit. p. 125). I was the first to point out the correct 
position of this bed in my paper on the Bourton line. 
To obtain the further sequence of the strata, it is necessary 
to return to the seventh cutting. This gives the following 
section :—
