492 GEOLOGY OF OHIO. 
stone is seen on the north side of March Run Hill, toward the foot of the 
hill. If this limestone continues eastward to Duck Creek with the usual 
dip, 1t would appear on Duck Creek at Stanleyville. The same Stanley- 
ville limestone is seen on some of the eastern tributaries of Duck Creek. 
On Killwell Run, on the farm of Lewis Dowling, the limestone is well 
seen. Here the following section was taken :

Passing over the ridge to the south-east into Lawrence township, we 
find on Little Hight-Mile Run, about a third of a mile from its mouth, a 
similar body of limestone. The “sandstone seam” is found at Guyton’s 
Mill, at the mouth of Little Hight-Mile Run, on Little Muskingum, un- 
der the heavy sandrock. No measurement was made of the interval, but 
I should think the limestone to be about fifty or sixty feet above the 
“sandstone coal.” These observations would tend to verify the other. 
MARIETTA TOWNSHIP. 
This township is situated on the Ohio River, and embraces within its 
limits the mouths of the Muskingum and Little Muskingum rivers and 
Duck Creek. The shape of the township is such as to give a very large 
frontage on the Ohio, and, consequently, a large area of the rich soil of 
the immediate valley. The valleys of Duck Creek and Little Mus- 
kingum are much narrower. The township is generally hilly, as are 
almost all townships bordering on the Ohio River. The city of Marietta 
is built in part upon a Drift terrace, and in part upon the alluvial 
ground bordering the Ohio and Muskingum rivers. The terrace is a high 
and beautiful one, affording a dry soil, and is admirably fitted to be the 
site of a town. Terraces of about the same level are seen upon the: 
opposite side of the Muskingum, a mile and a half above Harmar, and 
on the West Virginia side of the Ohio. A very extensive terrace is 
found in the upper part of Marietta township, above the mouth of the 
Little Muskingum River. All these terraces tell a tale of very high |
