326 Reports to the Bristol and Taunton Canal Company y 



This section shows the position in which the sundry veins 

 of coals lie in the ground, and exactly in a parallel direction 

 with the substratum, the limestone. I have already pointed 

 out two proofs at Nailsea Colliery, of the veins and strata 

 becoming flat in the deep, and afterwards rising southward; 

 and if the Nailsea veins reallv do so, there can be no mannec 

 of doubt of all the other veins of coal and strata, acting and 

 laying in the same manner. There is also positive proof, 

 that the limestone takes a dip from the north side, (where 

 the same is observable at Belmnnt, VVraxall, and Clevedon- 

 Courl) to the southward ; and from the south side to dip 

 northward, observable at Backwell V^illage, at Chelvy, Mr. 

 Piggott's, &c. ; which proves the uninterrupted continuity 

 of the limestone all the way underneath. 



No. 5, is a rougli sketch Plan of the north and south lime- 

 stone, which contains the vein? of coal, in the range from 

 Backwcll collieries to Nailsea, Nail sea- IVJoor, Kenn-Moor, 

 and the inclosed lands westward, from thence to the sea, — ? 

 where 



Ofl. are Messrs. Grace's veins of coal at Nailsea, dipping 

 southward. 



I h. are the supposed crops of the same veins, dipping north- 

 ward. 



c. is the east end or crops of the same veins, dipping west- 

 ward. 



dd. are the crops of White's veins, dipping southward. 



ee. are the supposed south crops of the same veins, dip- 

 ing north worth. 



f. is the supposed east crop of the same veins, dipping 

 westward. 



gg. are the Backwell veins, dipping southward. 



A k. are the supposed south crops of the same veins, dipping 

 northward. 



i. is the supposed east crop of the same veins, dipping 

 westward. 



And the centre or hollow of the supposed basin is along the 

 dotted line III. 



The north, the south, and the east outcrops of these veins 

 arc here delineated ; but the west crops cannot be ascer- 

 tamed, for the basin seems to widen very much going west- 

 ward. It is not a mile wide on the surface at A. There 

 is no doubt, I think, of each having a west outcrop, but it 

 may be at many miles disiancc, under the sea, where the veins 

 of coal may have ijicreased in number as tlie basin became 

 more extended ; and as the level course of the veins and 



strata
