THE OHIO COAL MEASURES. 225 
be reached by a shaft of 75 feet, the last-named seam likely to be a coking 
coal of high grade, would seem to constitute the coal resources of the 
Nebo field. 
Gas wells are easily obtained here, and indications point to a fairly 
permanent supply. Salt water is also within easy reach. 
To establish the fact that the Nebo coal is the Roger seam, a line 
of sections was run from Hammondsville to the above-named locality. 
The exposures were all that could be desired, and the identifications of 
the notable elements are positive and unequivocal. The intervals are 
either steady and normal, or else they change gradually so as to leave 
no obscurity in the sections. 
At Hammondsville, five coal seams are well shown, as represented 
in Fig. XIII. All of these but the Groff seam go below drainage in 
the great southern bend of Yellow Creek, south of Hammondsville. 
The valley has an easterly direction for a little while, leaving the strata 
level. It then ascends in a northwesterly direction and the strata 
gradually rise, bringing the Roger coal out of cover not far below the 
mouth of Brimstone Run. From this point to Nebo, the course is again 
east and west and the strata rise with the valley, the Roger coal holding 
its place a few feet above drainage—all of the way. 
From Hammondsville to Saltsman’s, the Upper Freeport coal (Big 
Seam) is thin and worthless. It mends somewhat here and averages 3 
feet in thickness as far as Moretown, and the quality is good. From 
the last-named points westward, it has no value, and though its limestone 
and fire-clay continue, as at Nebo, there is scarcely a black mark to 
stand for the coal. The Brush Creek seam comes and goes, but the 
Roger seam is found where it is due, and wherever it is shown, it is clean 
and bright and regular. 
The Lower Coal Measures of the first tier of counties on the eastern 
border of the State have now been briefly described. The chief centers 
of production have been noted, and the general conditions under which 
the coal exists and is mined have been pointed out. 
The same line of facts will be taken up for the same measures in 
the counties next in order, viz., Portage, Stark, Carroll, Tuscarawas, 
and Guernsey.
