MINABLE COALS OF THE MONONGAHELA SERIES. 



THE REDSTONE COAL. 



The Redstone Coal, discussed previously in Chapter 

 VI, page 124, and shown by outcrop lines on Map II, in 

 those regions where it occurs in minable thickness above 

 drainage, is a very valuable bed of fuel in northern and 

 eastern Lewis, but, so far as known, does not occur in 

 minable thickness in Gilmer. In those portions of Lewis 

 County where it occurs, it varies from 2 to 6 feet in thick- 

 ness and usually carries no slate partings, but is damaged 

 to a considerable extent by clay seams that frequently 

 cross it. Its chemical composition shows it to be a fine 

 coal for steam and domestic fuel and in some regions the 

 sulphur content is low enough to permit its use for coke manu- 

 facture. Figure 5 shows its probable minable extent. 



Redstone Coal, Hackers Creek District, Lewis. 



In Hackers Creek District, the Redstone Coal is above 

 drainage along all the principal streams and has been mined 

 for local fuel in numerous places, making it possible to observe 

 it closely. In the northwestern part of the district, along the 

 Chestnut Ridge and Wolf Summit Anticlines, only a small 

 amount of this coal still remains in the hill tops, but in the 

 eastern and southern parts there is a large body of this coal 

 that varies from 4 to 6 feet in thickness. This coal has been 

 mined commercially at one point within the area, near the 

 Harrison Line, where it was examined and sampled by Teets 

 and the results published in the Doddridge-Harrison Report 

 of the Survey, page 572, as follows :
