BELMONT COUNTY. 267 



to ten inches from the bottom there is frequently a thin streak of pyrites 

 about one-fourth of an inch thick. Throughout the bed, at distances 

 varying from four to six inches, there occur charcoal seams, rarely more 

 than one-eighth of an inch thick, and with difficulty traceable in the 

 solid coal, though very distinct near the outcrop. Nodules of pyrites oc- 

 cur in manjr banks, but are easily separated. Excepting in Warren 

 township, the coal appears to be of excellent quality, and, aside from the 

 portions referred to, comparativelj' free from pyrites. 



The relations of the Pittsburgh bed to those above it are of no little . 

 interest. The three beds, marked No. 8rt, No. 86, No. 8e, are found only 

 in the eastern portion of Belmont, and are absent in western Belmont as 

 well as in Harrison and Guernsey, while they are only doubtfully pres- 

 ent in southern Jefferson. It is observed that in the eastern portion No. 

 8c is about one hundred feet below Coal No. 10, while in the west No. 

 8 occupies that position. Prom Bellair to the summit of the Central 

 Ohio Railroad nine coals are seen, beginning with the Pittsburgh, while 

 from the summit westward only six coals appear in the section. In both 

 sections the succession is the same from the top to Coal No. 9, below 

 which the sections differ, as shown on a previous page. That the lower 

 coal worked at Barnesville is the Pittsburgh there is no room for doubt, 

 and that the upper coal is No. 10 is equally certain, for that coal can be 

 traced, without any difficulty, from Barnesville round the divide back to 

 the railroad at Belmont, and thence along the road to Glenco; thus giv- 

 ing indisputable evidence that it is not the Glenco coal (No 8c), as has 

 been maintained by some. The accompanying plate of grouped sections, 

 arranged with Coal No. 10 as the base, shows the matter very clearly. 

 The sections are as follows: No. 1, from Bellaire ; No. 2, from Glenco; No. 

 3, from Warnocks; No. 4, from Belmont; No. 5, from Belmont to Morris- 

 town, three miles; No. 6, from Morristown to Badgersburg, two miles; 

 No. 7, from Badgersburg to Railroad summit, two miles ; No. 8, from Rail- 

 road summit to Spencer's, along the railroad. 



A reference to the map will show at once the relative geographical 

 positions of these localities. 



In order, however, to remove all doubts respecting the identity of the 

 coal at Barnesville the following sections were compared : 



No. 1.— Bellaire to railroad summit. No. 2. — Bailroad summit to Spencer's.
