LOWER OOLITIC ROCKS OF ENGLAND : 
The beds here are very changeable in character within short 
distances. The Gas House Quarry, half a mile north of Ciren- 
cester, described by Prof. Buckman, showed beds that probably 
correspond with those noted in the above section. It was carried 
to a greater depth, so that he describes 35 feet of stone-beds 
beneath the top rubbly layers. He moreover records Wald- 
heimia digona from " Bradford Clay," evidently a portion of the 
3 feet of rubbly beds above mentioned.* 
North of Stratton there is considerable difficulty in tracing out 
the sequence of the beds, but there are several quarries along the 
main road. In one of these we find a section showing about 
10 feet of false-bedded oolite, shelly in places, and yielding 
Strophodus and Ostrea, representing the Upper (Kemble) Beds. 
East of Daglingworth the connection of these with the under- 
lying beds, was shown in a quarry north of the 15th milestone 
as follows :

Dagham Stone. 
In the neighbourhood of Cirencester there are found layers and 
blocks of Great Oolite characterized by irregular and ramifying 
tubiform cavities. Where the stone is in situ and protected from 
the direct influence of the weather, the cavities are usually filled 
with ochreous material ; where exposed to the action of the 
weather, the cavities in the stone have been emptied and enlarged. 
Irregular blocks have been obtained for rustic work or rockeries, 
on Dagham or Daglingworth Downs to the north of Cirencester. 
Attention has previously been called to stone of this character, 
under the name of " Dagham Stone." Referring to this rock, 
my father, S. P. Woodward, has stated that " In Gloucestershire 
there is a bed of the Great Oolite, called ' Dagham Down Stone, 
because it forms the substratum of a large extent of (formerly) 
down-land. This must have originally enveloped a continuous bed 
of sponges, or something of the kind, for now the rain eats into 
it irregularly, leaving holes such as one could make with the 
fingers in dough."t
