64: THE STEUCTUKE OF THE GULLY, DUEDHAM DOWNS. 
D. Reddish-brown shales, weathering cream-colonred. 
— 2 feet. 
E. A rubbly limestone band, with fracture very similar 
to C. Locally, especially in its upper part, it is scarcely at 
all rubbly. — 2 feet. 
F. Brown shales and thin bedded limestone, often absent, 
derived chiefly from splitting of E^ never more than a few 
inches thick. Variable. 
Gully Oolite. 
G. Gully Oolite, hard, white, and thickly set with round 
oolitic grains. Newly fractured surface, white and slightly 
rough, showing the grains ; contains a few crinoid stems. 
—120 feet. 
H. Coarse Oolite, darker, the oolitic 'grains much further 
apart, full of fragments of shells, fair specimens of spirifers 
crinoid stems and a few corals. Soft. 
—17 feet. 
Loiver Limestone. 
J. Yellowish-white rock with a flnely granular weathered 
surface ; usually very dark on fracture. 
K. White rock with a flnely granular weathered surface, 
silver-grey or dark when broken. 
The whole series dips at 26° to the S.S.E. 
It is interesting to notice how the surface contour of the 
Gully, shown in the sketch map, reflects the characters of 
these beds. The Gully arises by two main heads, and a 
small accessory one on the north side. This last corresponds 
to the Coarse Soft Oolite JI. The North Head corresponds 
to beds C, D, -E, F. The South Head corresponds to 
the shales just above A, which is exposed on its northern 
slope. 
There is a marked shelf on the southern slope at the top 
of the hard Gully Oolite G. 
Behind the road, shallow depressions may be traced
