ATA GEOLOGY OF OHIO. 
some of the shales contain limestone in small concretions. Sometimes 
in place of such concretions we find regular strata of limestone. 
Sandstone is the most characteristic rock in the hills, and formerly 
many of the hills were crowned with yellow pines, a tree that thrives 
on highly silicious soil. In the hills bordering the river large quarries 
have been opened in the heavy sandstone ledges, and vast quantities of 
stone have been removed. The stone for the piers of the railroad bridge — 
across the Ohio at Parkersburg came very largely from a Dunham 
quarry. Other excellent quarries have been opened, and stone for build- 
ing purposes is shipped down the river. The selected stone makes 
superior grindstones, and large numbers are annually made and sold. 
Mr. B. HE. Tilton, D. Briggs, and others, are engaged in this business. 
The old quarries of the late Oren Newton, where grindstones were ob- 
tained forty years ago, are in this township. The sandstones of this and 
of Warren townships are of the most excellent quality, are convenient 
to river and railroad, and cannot fail in the future to be sources of great 
wealth. 
ADAMS TOWNSHIP. 
This township lies directly east of Waterford, and is traversed by the 
Muskingum River. The chief affluents of the Muskingum, which drain 
the township, are Big Run and Cat’s Creek. There is considerable lime- © 
stone in the hills, and the soil is generally rich and productive. There 
is an almost unlimited supply of coal of fair quality to be found nearly 
through the whole township north of the river. The dip is generally to 
the south, but we find the seam also gradually rising to the east on the 
waters of Big Run, Cat’s Creek, and Bear Creek. The following section 
was taken on the hill below Coal Run village, near Hwart and Mills’s 
coal bank:
