COAL. 



maining parts of the district, where the horizon of the coal 

 is exposed, little more than the blossom of the coal is found, 

 indicating that the entire district contains no Pittsburgh Coal 

 of minable thickness, and its outcrop is not placed on Map II. 

 The Redstone Coal above it has often been confused with the 

 Pittsburgh in this district, but the stratigraphic evidence re- 

 garding the two coals is conclusive, making it certain that 

 the Redstone, and not the Pittsburgh, is the minable coal of 

 the lower part of the Monongahela Series in this district. 



Pittsburgh Coal, Troy and Dekalb Districts, Gilmer. 



In Troy District, the Pittsburgh Coal is of minable thick- 

 ness in only a small area in the southeastern corner, where it 

 is a good seam, varying from 4 to 8 feet in thickness. The 

 western line of disappearance, shown on Map II, indicates that 

 the coal is not found west of Troy. Its horizon is exposed 

 along Leading Creek and tributary streams in the southern 

 end of the district, but beyond Troy no coal occurs where the 

 Pittsburgh should belong. In the western end of the district, 

 where its horizon is underground, no Pittsburgh Coal is re- 

 corded in any of the well records secured in this region, and 

 as many of these records are complete, there can be no doubt 

 that the coal is absent in this region. In the southeastern 

 corner, several openings were observed, and in this region 

 the outcrop is shown on Map II. 



The E. M. Talbott Farm Mine (No. 152 on Map II), on 

 Leading Creek, 1 mile east of Troy, had fallen shut, but was 

 reported by Mr. Talbott to have shown 3 feet of coal, its 

 elevation being 830' B. The coal has been opened, also, at 

 several points along Fink Creek, between the Lewis Line and 

 its junction with Leading Creek, but all these have fallen shut.
