INFERIOR OOLITE : ANCASTER.

Mr. Jukes-Browne mentions that beneath the main freestone^ another 
bed of ragstone (1 ft. 6 in. to 2 feet) and below it a fine-gained freestone (of 
similar thickness) have been worked. Palatal teeth of Strophodus and a 
Saurian vertebra have been obtained below this lower bed of freestone.* 
In old times stone was extensively quarried at Pits Hills 
Plantation, south of Ancaster. At this locality there was no 
protecting cap of clay, but building-stone of excellent quality was 
obtained, though I am informed not in blocks of large size. 
No doubt a considerable amount of walling-material was pro- 
cured, while if the good stone was in small blocks, it had to a 
great extent proved its character by having withstood the effects! 
of long weathering. An open quarry showing the character of 
the beds was to be seen to the north of Copper Hill. (Fig. 59.) 
The stone remains to

some degree moist in its

depth from the surface, 
drying and hardening 
after it is quarried. 
Here as in other cases, 
the stone should be 
dressed for use while the 
quarry-water still re- 
mains. For I am in-

stone from ancient build-

weather, is not durable if dressed

The beds of ^freestone are muchjointed ; here and there a more 
massive bed [appears, but this becomes disintegrated in places 
where long subjected to atmospheric influences.
