No. 18.) The highest part of the ridge cannot be less'than five hundred 

 and fifty fe t above the Ohio River, and it may be six hundred feet. 



On the land of Ezekiel Mills is a layer of limestone. It is probably not

 hill. Nothing more of geological interest could be found among these 

 high hills. 



GEEEN TOWNSHIP. 



This is an irregularly shaped township, lying west of Ohio township. 

 It is drained chiefly by the Little Muskingum River and its branches, 

 excepting: the eastern part, in which are the heads of Possum Creek. A 

 section was taken on the land of Harvey Huffman, disclosing three 

 seams of coal. The section is as follows :

The middle seam of the above section, or No. 5, is worked near New- 

 castle, where it is two feet thick. It is said to be of excellent quality. 

 No other seams were seen in this township. 



OHIO TOWNSHIP. 



This township is situated upon the Ohio River. Prom the curves of 

 the river it has a long stretch of river border, and, consequently, a large 

 area of rich alluvial vallev land. The hills back from the river are very 

 high. The north-western portion of the township is drained by Possum 

 Creek, which flows in a general north-eastern direction, and empties into 

 the Ohio in Salem township. The population is similar to that of 

 Switzerland township, and the cultivation of the soil receives very care- 

 ful attention. Near Sardis two seams of coal are found — the lower one 

 about ninety feet above the Ohio River, and the other about one hundred 

 and ninety feet higher. (See Map XIII., No. 10.) The lower was not
