MINERAL BASON IN WALTS. S(>5 



Carmarthen, Brecon, and no doubt can be entertained of 

 its due range from Newton across Swansea Bay to the 

 Mumbles, and from Llanmaddock Hill across Carmarthen 

 Bay to Tenby. In Pembrokeshire it appears to the surface 

 on the south side of the bason, at Tenby, Ivy Tower, Co- 

 chelard, Bit Church, Williamston, Lawrinny, Cord, Canta, 

 and Johnston ; and on the north side of the bason, at Tern- 

 pleton, Picton, Harriston, and Persfield; yet it certainly 

 forms an underground connection from point to point.
