track. It is probably the equivalent of the first seam below the tunnel 

 seam at Barnesville. 



In the cut a half mile west of Belmont Station a streak of black, bitu- 

 minous matter was seen, with yellow shales above and below. It is four- 

 teen feet above the level of the railroad track. This faint representative 

 of coal was supposed to be the equivalent of the highest seam at Barnes- 

 ville— that is, the one about forty feet above the tunnel seam. At Bel- 

 mont Station cut, the eastern descent of the road being greater than the 

 dip of the strata, this black, bituminous stratum is over thirty feet above 

 the track. About ten feet below the track, at the east end of the cut, is 

 a 'seam of coal. This seam was believed to be the Barnesville tunnel 

 seam. This belief is strengthened by finding in the valley farther east, 

 at the proper distance below, viz., about thirty feet, a seam of coal corre- 

 sponding to the one at Barnesville first below the tunnel seam. 



A section one half mile east of Belmont Station is as follows : 



Ft. In. 



1. Coal (the Belmont or Barnesville tunnel seam). 



2. Interval down to railroad track, composed of sandstones and shales 18 



3. From railroad track to next coal 12 



4. Coal (not measured). 



5. Not exposed in detail 27 



6. Limestone 3 to 5 



If we have brought the identifications along accurately from Barnes- 

 ville to Belmont, we are prepared to trace the group eastward. It should 

 be remarked, before leaving Goshen township, that the coal seams are 

 generally thin, and the coal is worked only to a very limited extent. In 

 the vicinity of the railroad stations, coal is generally procured from the 

 cars, brought from the mines towards Bellair. In section 14, in this town- 

 ship, Mr. Gilbert obtained the following geological section : 



Ft. In. 



1. Blossom of coal. 



2. Interval not exposed 100 



3. Blossom of coal. 



4. Interval not exposed 36 



5. Sandstone 2 



6. Shale 2 



7. Coal 2 6 



8. Clay and ferruginous shale 6 



9. Shaly limestone 1 6 



If we may consider the lowest coal in this section as the equivalent of 

 the lower seam at Lewis's Mill, i. e., the coal first below the Barnesville 

 tunnel seam, the next coal above, of which only the blossom was seen, 

 will be in the horizon of the tunnel seam, and the blossom, one hundred
