South of Straitsville, on the Snow Fork of Monday creek and its tributaries, the coal is everywhere largely developed; indeed, throughout
the whole of Ward township, Hocking county, the coal is to be found in
large development. It is unnecessary to designate locations; every farmer who owns hill land possesses the coal. In the valley of the Snow
Fork it dips below drainage not far from the south-east corner of Ward
township. The measurements on the lower part of Snow Fork showed
six feet of coal. This was at James Hawkins', Sec. 3, Ward township.
Higher up the stream the seam is said to increase in thickness, which I
readily believe, although there were no good exposures for measurements.
Near the head of the east branch, on the land of Alexander Marshall, in
Sec. 35, Salt Lick township, Perry county, the "big seam" was seen
largely developed. The opening was full of water, and no measurement
taken. It was claimed to be eleven feet thick. From this point, crossing the high ridge to the north-east, we came down into the west branch
of Sunday creek, where we found the coal in the low valley. Here it
ranges from six to eleven feet in thickness. At Gaver's mill, and on the
adjacent land of L. M. McDonald, Esq., near the Coal Dale P. O., Salt
Lick township, the seam measures six feet two inches. The following is
a section taken at the mill. (See Fig. 18.)'30 to 40 / Heavy Sandraoe

Here there is a good slate roof, very rich in coal plants. At the Lyons
bank, half a mile above, the coal is 7 ft. thick, and of very excellent quality.
Lower down the stream the upper slate is gone, and the sandstone has cut
away the coal. At one place the coal was only 3 feet 8 inches, and at
other places it was entirely gone. In that neighborhood, over a limited
area, the waters, in the coal measure era, took strange liberties with the
coal after it had been deposited. This will be noticed more fully hereafter.
