506 GEOLOGY OF OHIO. 



The same coal with that of the above section is found and mined in a 

 small way at other places, and on other runs. A buff limestone is some- 

 times found, but it is not persistent, as it is in places replaced by heavy 

 sandstone. 



LUDLOW TOWNSHIP. 



This township lies east of Liberty, and borders Monroe county on the 

 north. The Little Muskingum River flows through the township, en- 

 tering it near the north-west corner, and leaving it near the south-west 

 corner. Its course is very winding. The township is entirely drained 

 by it and its tributaries. Its geological features are essentially those of 

 Liberty, but with less coal. 



On Wingett's Run, in the western part of the township, some sections 

 were taken, which show the Cumberland, or upper Salem, seam of coal, 

 and the lower Salem, or Pomery seam. The following geological section 

 was taken in section 34, on the land of Albert Ewing :
