Eastwardly from Bamesville the surface rises rapidly and the beds 

 fall so that the highest portion of the section alone can be followed 

 for 10 miles. A deep cut on the railroad summit several miles east 

 from Barnesville shows the highest bed 2 feet thick and, near by, the 

 Tunnel seam is represented by 2 feet of black shale containing some 

 coal. It underlies yellow shale as at Barnesville and a thin coal below 

 answers to Number 8 of the section. Near Belmont, 7 miles from 

 Barnesville, the three coal beds are recognized, the intervals being ap- 

 proximately 40 and 30 feet, and just beyond Belmont the lowest coal 

 bed is 27 feet above a limestone. At 3 miles south from this locality 

 a coal bed is at 100 feet above the Tunnel seam and another at 40 feet 

 below. The section remains perfectly clear along the railroad to Lewis 

 mills, in Smith township, where the succession is :

The group is followed to this place from Belmont easily, as the road 

 falls somewhat more rapidly than the beds ; but there is a notable increase 

 in the intervals. At Barnesville, from the bottom of the highest coal 

 bed to that of the lowest, the interval is 76, but here it is 97 feet. These 

 beds are present at 7 or 8 miles south from Lewis mills, where they 

 are 5, 2, and 3 feet thick respectively and the intervals are 46 and 42,
