LOWER OOLITIC ROCKS OF ENGLAND: 
shelly and oolitic limestones, evidence of which is furnished by a 
section at Pool Road Bridge, near Pool Keynes, south of Kemble, 
recorded by Prof. Buckman.* No beds of sand or sandstone 
appear to have been met with in borings through the Forest 
Marble at Cirencester ; but Prof. Hull gives a section near Sandy 
Lane, south of Cirencester, showing " Slaty false-bedded oolite, 
with oysters," resting on " Soft yellow sands, with large blocks 
of chert."t (See Fig. 104.)

b. Soft yellow sands, with large blocks of hard siliceous lime- 
stone or calcareous sandstone. 
In a quarry south-west of Long Furlong near Ampney (or 
Eastington), there were exposed about 10 feet of oolitic shelly and 
sandy limestones, with occasional layers of fissile micaceous and 
calcareous sandstone, and a few clay-seams (see Fig. 105). A 
considerable mass of these beds had been disintegrated and 
partially dissolved by atmospheric agents, to a depth of 5 feet and 
over a breadth of 25 feet. 
West of Barnsley Church, there was a quarry showing about 3 
feet of limestone with clay -bands, resting on 9 ft. 6 in. of false- 
bedded limestone with here and there horizontal partings of clay. 
The beds are used for tiling and road-metal.
