Dundry, and J mile to the east thereof. It is known to be absent 

 at Clements' Yard, Barns Batch Spinney, and Maes Knoll. There- 

 fore in a westerly direction it has been removed entirely in | mile 

 from the main road, and in an easterly direction it probably fails 

 in about f mile east of East Dundry. North and south it is cut 

 off by the escarpment. Consequently the Ironshot Oolite occupies 

 an area in the middle of the hill only, and its extent cannot be 

 more than 1| miles long (from east to west) and about 1 mile wide 

 (from north to south). The reason for the limited east-to-west 

 extension of the Ironshot is in all probability denudation soon after 

 its deposition, to which the flat top of the Ironshot itself bears 

 witness ; and the planed-off top of other beds where the Ironshot 

 is not present also tells the same tale. The theory of a limited 

 area of original deposit in regard to the east-and-west extension 

 would involve the hypothesis that the sea- bottom of the western 

 portion of the hill was elevated after the deposition of the Lower 

 White Ironshot (Sonninice hem era). 



(8) The Geographical Extent of the Freestone. 



This is a matter of considerable economic importance. We are 

 able to show that the Ereestone thins away very rapidly, and also 

 loses the freestone character, as we proceed from Dundry Church 

 eastward — the Northern Main-road quarry (Section IV.), and south- 

 eastward — the Southern Main-road quarry (Section IX.). These beds 

 thin away and deteriorate so rapidly that it is very doubtful whether 

 workable building-stone of good quality would be found | mile east 

 of the church. Westward, on Dundry Down, the old workings 

 for freestone are very numerous, occupying a considerable area, 

 and it is probable that nearly all the good stone has been obtained 

 in that direction. There remains, however, the ground east of the 

 Down and south of the church, an area about equal in extent to 

 that which has been worked for stone ; and this may certainly be 

 expected to yield freestone of good quality. Farther south, in 

 the direction of Barns Batch, there is a considerable thickness of 

 stone, but its quality would seem to be inferior to that of the 

 Freestone proper. It is unfortunate that for want of suitable 

 exposures we are not able to give more precise details concerning 

 the construction of the hill between the Winford road and Barns 

 Batch ; but it is obvious that the area over which workable freestone 

 is likely to be found is a very restricted one. Our investigations 

 indicate that it certainly extends very little to the east or south- 

 east of the village, and certainly is wholly confined to the portion 

 of the hill westward of the main road.
