The lithic characters of the beds proved in the bore-hole, 
and of those seen in the railway-cutting also appear to be very 
similar. Cores from a single bore-hole obviously do not afford 
any information with regard to the lateral variability of the 
beds, and my task of describing the rocks is rendered the more 
difficult from the facts that the softer sandy layers did not 
yield a core — only loose sand, and that I have only the fore- 
man’s account available as to tlie nature of these softer de- 
posits. 
Alongside the reproduction (page 53) of Messrs. Reynolds 
and Vaughan’s general account of the Forest Marble beds on 
the line of railway, I have indicated the depths between which 
occur in the bore-hole the deposits probably on the same horizons 
as those groups noted by them. 
The ground all around Shipton Moyne is very heavy, and 
there is no doubt that the beds proved down to a depth of 12 feet 
7 inches belong to the lower portion of their group 8 — “ Shale.” 
The beds between 12 feet 7 inches and 27 feet no doubt 
correspond to their group 7. A fair-sized heap was made 
of the sand drawn for the most part when the boring was going 
through these beds. It is doubtless these beds which, when 
at the surface, weather to an incoherent sand-deposit with 
doggers and fiat pieces of sandstone, many of which are fissile 
and have yielded ” tilestone.”^ 
Large brownish ” clay galls ” are of frequent occurrence 
in the hard layers in the beds between the surface and 27 feet 
down. 
Some of the limestones in the series between 34 feet 7 inches 
and 57 feet are fissile. 
Great Oolite. — As no cores were drawn between 58 
feet and 100 feet 6 inches, I have no information to add to that 
given me by the foreman and recorded on page 50. The beds 
between 67 feet 6 inches and 100 feet 6 inches — 33 feet thick — 
occupy the stratigraphical position of Reynolds and Vaughan’s 
groups F, E, and D, which are about 35 feet thick. 
Rotary boring commenced at 100 feet 6 inches, and nice 
compact cores of the familiar yellowish Great Oolite limestone 
were drawn from down to a depth of 152 feet 2 inches.
