520 GEOLOGY OF OHIO. 



The coal in the above section is the "Upper Barnesville," or Cum- 

 berland seam. No measurement was made, but in this region it ought to 

 be found thick enough for working. The cement limestones are promis- 

 ing. The distance from the railroad would probably make the manufac- 

 ture of cement lime unprofitable at present. 



Whether the Cambridge seam of coal exists in full thickness below the 

 surface in this township, can only be known by trial borings. Such 

 borings would not be expensive if located in the deeper valleys. The 

 place of the Cambridge seam is proximately five hundred and ten to five 

 hundred and twenty feet below the Cumberland seam, or two hundred 

 and ten to two hundred and twenty below the Ames fossiliferous lime- 

 stone. This limestone is seen in the township. It is about three hun- 

 dred and twenty feet below the Cumberland seam of coal. 



WAYNE TOWNSHIP. 



This township lies on the northern border of the county. Wills Creek 

 flows through the township in a north-west direction. The soil is gen- 

 erally most excellent. Probably few of the hills are high enough to 

 take the Cumberland seam of coal, and the Cambridge seam is below the 

 bed of Wills Creek. 



A section taken near Kennonsburg shows the following limestones : 



Ft. In. 



1. Heavy limestone in layers 18 



2. Not exposed 27 



3. White limestone 2 



4. Not exposed 80 



5. Fossiliferous limestone, Ames limestone 2 



(See Map XII., No. 24.) 



The relations of the Ames limestone both to the Pomeroy and Cumber- 

 land seams may be seen from Map XII., as also its relations to the 

 Cambridge seam, which is below. There are some seams of coal which 

 are elsewhere found in the geological range of the vertical space in the 

 above section, but they are always thin. 



BEAVER TOWNSHIP. 



This is the north-eastern township of the county, and is one of the 

 richest in agricultural resources. Its valleys are very fertile and very 

 beautiful. The hills abound in limestone, and many of the shales are 

 rich in lime.
