LOWER OOLITIC ROCKS OF ENGLAND : 
whitish mudstone ; the corals are crystalline, and are extracted 
with difficulty. Their structure is best seen in polished hand 
specimens ; these can always be obtained from the broken heaps 
of stone on the sides of the road repaired with it, and can be 
easily ground to a smooth surface and polished." The Coral Bed 
can be traced from Haresfield Hill to Painswick Edge and Stroud, 
and again to Witcombe, Crickley, and Cubberley.* The par- 
ticular places at which it has been observed are Juniper Hill, near 
Painswick, Huddingknoll, Horsepools, Sheepscombe, Birdlip, 
and Crickley. This Coral Bed is [sometimes termed the Fourth 
or Lower Coral Bed (in descending order) in the Inferior Oolite 
of the Cotteswold Hills.

FREESTONES AND OOLITE MARL. 
The Lower Freestone Beds consist of pale oolite often hard 
and compact at the top, more or less shelly in places, but on the 
whole sufficiently free from organic remains to be readily dressed 
into blocks for building- purposes and for carving. 
The beds are locally overlaid by a band of oolitic marl, 5 to 
10 (and rarely 30) feet thick, with indurated layers of oolite in 
places. Known as the Oolite Marl, this division is not always 
distinctly separated from the Lower Freestone below, while it 
more frequently merges into the Upper Freestone above.
