576 GEOLOGY OF OHIO. 



Traces of two higher seams of coal were seen, but the seams are no- 

 where opened. They are probably thin. Limestones are found in the 

 hills, which tend to fertilize the soil. 



BENTON TOWNSHIP. 



This township is situated upon the southern border of the county. It 

 is east of Washington and west of Jackson townships. The Little Mus- 

 kingum River flows through it. 



No very interesting geological facts were obtained here, the only coal 

 seam mined, so far as could be learned, being one of the higher ones. The 

 upper part of the seam is often quite slaty. On the land of Eli Eddy, 

 section 11, the seam is mined, and found to be three feet thick. This 

 seam is believed to be the same as that found on the lands of Wm. Raper 

 and George Shy, section 34, Jackson township. 



About thirty feet, below the coal in Jackson township is found nodular 

 iron ore. It is worth looking for in the same geological horizon in Ben- 

 ton, for it may be found to exist in a regular seam of much value. 



In section 18 a seam of coal is reported to be four feet thick — three feet 

 of it slaty^— overlain by thirty feet of sandstone. 



PERRY TOWNSHIP. 



This township lies east of Washington, and is wholly upon the waters 

 of the Little Muskingum. There is much limestone in many of the 

 hills, and the soil is generally good. 



Coal is seen at several points. At Basil Dye's, section 21, the seam is 

 unusually thick for this region. A geological section at this place re- 

 vealed the following :

This seam of coal is thought to be the Cumberland seam, and is so 

 grouped on the map. There are so many changes of dip and undula-
