On the farm of Benjamin Saunders, Monroe township, Perry county,
on the west branch of Sunday creek, the coal measures eleven feet. Here
there are two slaty partings. (See Fig. 19.)

The exposure shows a magnificent body of very superior coal. The
coal shows itself at other points on this branch, but no other measurements were taken. The coal in this valley generally lies low, but in
mining it to the north and north-west, every advantage can be taken
of the dip for easy mining and drainage.
In all the tributaries of Sunday creek which have the requisite erosion,
we find the coal. In the branch which runs through the southeast section of Pleasant township, Perry county, we find the coal in full thickness, measuring at the bank of Joshua Sands, 11 feet 2 inches, with
several clay partings. At the bank of William Bennett, a little above,
it is probably as thick; the water preventing, at the time of our visit, a
full measurement. In this neighborhood the coal lies too low for easy
drainage, but the difficulty can be obviated. A vast body of coal in the
hills to the north, can be mined up the dip from this valley. There is,
scarcely, no limit to the coal, which is rendered accessible by the various
branches of Sunday creek, in Pleasant, Monroe and Salt Lick townships.
The great body of high lands which constitute the divide between the
waters flowing souh andth ose flowing north, through Jonathan's creek,
into the Moxahala and Muskingum, and west through Rush creek, into
the upper Hocking, is doubtless underlaid with this coal. The coal seam
constitutes a vast sheet, of 11 feet in maximum thickness on the south,
but gradually growing thinner, to 4 and 5 feet, in its northern out-crop
along the Zanesville & Cincinnati Railroad. The value of the upper
Sunday creek valley as a coal field, cannot be over-estimated.
North of Straitsville, the higher grounds take the coal. Two and a
