BELMONT COUNTY. 545 
McMahon Creek the interval between the two seams ranged from eighty 
to ninety feet. 
The upper Bellair, or upper Barnesville, seam is one of wide distribu- 
tion in the Second Geological District. It is the Cumberland seam of 
Guernsey, Noble, and Washington counties, and is traced through Mor- 
gan into Athens, where it is pretty well developed on Big Run, in Rome 
township. It was not seen in Meigs county. 
My associates on the survey in the First Geological District have 
classified the coals on the Ohio River, in this county, in the descending 
order, as follows: | 
Coal No. 10, No. 9, No. 8¢, No 8d, No. 8a, No. 8 (Bellair, or lower 
Barnesville). 
We trace the same seams in the same order through all the high lands. 
of the Barnesville region. We could find no coalescing of seams in going 
from the Ohio River west, by which 8a, 8, 8c, and 9 unite with 8. Mr. 
Bundy and myself have found all these on the west side of the Barnes- 
ville ridge. For example, 8a is seen faintly in a railroad cut west of 
Barnesville; on the turnpike north of Barnesville; on the turnpike 
between Flushing and Rock Hill; on “Belmont Ridge,” in Flushing 
township, and at other points. It even extends through several counties. 
No. 80 is distinctly seen at all the above-named localities. No. 8¢ is the 
upper Barnesville seam, and is the Cumberland seam, which can be fol- 
lowed through Guernsey, Noble, Washington, Muskingum, Morgan, and 
Athens counties, always holding the same relation to No. 8, or the Pom- 
eroy seam. No. 9 is constantly found in western and north-western Bel- 
mont. Traces of it are seen farther west. It is doubtless the Hobson 
seam of Washington county. 
In Belmont county there are about sixteen miles of Ohio River border 
in the Second Geological District, ¢. é.. below the mouth of McMahon 
Creek. The total fall of the Ohio River in this distance is 11.066 feet, 
or about an average of 8.28 inches per mile. The fall is, however, un- 
equally distributed between the ripples and pools; the former having 
10.41 feet, and the latter 0.656.inches. There are 4.327 miles of ripples. 
and 11.673 miles of pools, seven feet deep in low water. 
WARREN TOWNSHIP. 
This township is located in the western part of the county, and is: 
traversed by the Central Ohio Railroad. The township is drained by the. 
waters of Captina Creek, flowing into the Ohio, on the south-east, by- 
Stillwater Creek, which flows into the Tuscarawas, on the north, and by:
