BELMONT COUNTY. 553 



find a mere trace of coal, which probably represents the seam in the 

 tunnel at Barnesville. The following is the section in this cut : 



Ft. In. 



1. Shaly sandstone, with yellow shales below '. 8 



2. Nodular sandy limestone 2 



3. Bluish shale, yellow at top 12 



4. Black bituminous slate, with thin streak of coal 2 



5. Hard, ferruginous limestone 6 



6. Blue clay shale 3 



Level of railroad track. 



At Fairmount Station, or Burr's Mill, the same group as the last is 

 seen in a railroad cut. The only representative of the Barnesville tun- 

 nel seam is a black, bituminous shale, immediately over a ferruginous 

 limestone. The whole section is as follows : 



Ft. In. 



1. Shaly sandstone , 6 



2. Yellow shale at top, with black, bituminous shale below 4 



3. Ferruginous limestone 7 



4. Clay (unstratified) shale, blue at top, chocolate-colored below 12 



Level of railroad track. 



The unstratified clay shale corresponds remarkably with that seen in 

 the tunnel cut at Barnesville. 



In the second cut, east of Burr's Mill, the same group was found as 

 before, but with a larger development of limestone. It is given below : 



Ft. In. 



1. Yellow shale 5 



2. Shaly sandstone, changing below into yellow shale 9 



3. Ferruginous limestone 10 



4. Black, bituminous slate, no true coal seen 1 6 



5. Ferruginous limestone in nodules, often wanting 4 



6. Blue unstratified clay shale, with soft blue sandstone below 14 



7. Brown shale 6 ° 



8. Buff limestone 1 



Level of railroad track. 



This cut was estimated to be about six hundred feet long, and extends 

 in a north-east and south-west direction. The exposed strata in the cut 

 dip to the north-east in this short distance about twelve feet, by a proxi- 

 mate leveling with Locke's level. The railroad track is not far from 

 level. 



In a valley crossed by an embankment, a little east of this cut, a coal 

 seam was found which had been worked by stripping. This coal could 

 not be measured, not being well exposed. It is probably too thin for 

 drift mining. This seam is thirty-six feet below the level of the railroad
