Section 4. 



Seams in lower coal-shale, worked at Whitehall, and also at the distance of 

 about a mile to the west-south-west, near the foot of Lawrence-hill, behind 

 the Packhorse, on the north-eastern suburb of Bristol. The seams agree 

 with the lowest at Hanham ; but it is so long since they were worked, that it 

 has been found impossible to obtain more than an imperfect account of them.
