ATS GEOLOGY OF OHIO. 
is good, and some of the limestone strata found north in Adams extend 
into the hills of Union, but they show a tendency to thin out toward the 
south. The only coal observed is always thin. It is supposed to be the 
Hobson seam, the place of which is about one hundred feet above the 
Coal Run or Cumberland seam. At one place, not far above the mouth 
of Rainbow Creek, this seam is found, and is reported to be only eight 
inches thick. This township, since the formation of Muskingum town- 
ship, has lost the larger part of the Muskingum River, formerly within 
its limits, with the rich adjacent bottom lands. 
MUSKINGUM TOWNSHIP. 
This township lies north of Marietta, and includes the Muskingum 
River as far north as the mouth of Bear Creek. It, consequently, con- 
tains a large area of the immediate valley of that river. Its eastern 
boundary generally takes the summit of the ridge dividing the waters of 
the Muskingum and Duck Creek. The soil on the top of this ridge is 
not remarkable for its natural fertility, being composed largely of disin- 
tegrated sandstone and shales. In the northern part of the township 
some of the limestone found in the hills of Adams township serve a val- 
uable purpose in fertilizing the soil. These are seen in the hills near 
the mouth of Bear Creek. The following section was taken on the road 
leading from the Lutheran Church, on the ridge, down to Bear Creek, 
near the north line of the township:

8. Blue limestone, in bed of Bear Creek. . 
The section can be only proximately correct, as the dip was not known, 
and no allowance could be made for it. The place of the Bear Creek or 
Cumberland coal is about seventy-five feet above the buff limestone, but 
no trace of it was found. The dip of the strata on Bear Creek is sharply 
to the south. On the land of John Spears, a half a mile above the 
mouth of Bear Creek, a section was taken as follows:
