At Bellair and vicinity the lower and main seam of coal has been 
extensively mined for many years. It has been identified by the Penn- 
sylvania geologists as the Pittsburgh seam. It dips below the Ohio 
River, in this county, to emerge again in Meigs county, nearly one hun- 
dred miles in a straight line to the south-wesl. The Newell’s Run 
uplift, in Newport, Washington county, brings it to the surface, but 
it is here too thin to be of practical value. In the same uplift is the 
upper Bellair, or upper Barnesville seam, but it is alsothin. There are, 
unfortunately, no valuable seams of coal directly upon the Ohio River 
between Belmont and Meigs counties. This fact gives no little imp r- 
tance to the coals of Belmont county. The Bellair or Wheeling coal ig 
highly bituminous and cementing, of good heating power, and makes a 
durable fire. It requires a strong draft for its best combustion, and con- 
siderable stoking. It is used in rolling mills, for the generation of steam, 
and for all household and ordinary uses. The great seam underlies 
nearly the whole of Pultney township, and is a source of great prosperity 
to the region. A careful geological section was taken at Bellair, which 
is of great interest in showing the remarkable limestone formation above 
the horizon of the Bellair or Wheeling seam of coal. The section is as 
follows:
