500 GEOLOGY OF OHIO. 



near Germantown, in section 23, the following geological section was 

 taken : 



Ft. Ia. 



1. Heavy sandrock (exposed) 22 



2. Blueshale 8 



3. Coal, Cumberland seam 2 6 



4. Clay, " " 2 



5. Coal, " " 2 10 



6. Clay and shale / 5 



7. Limestone 2 



Bed of Pawpaw Creek. (See Map XL, No. 23.)' 

 This is the Cumberland seam. In another coal bank, near by, the di- 

 viding clay is only ten inches thick. On the land of Edward Doyle, 

 section 16, the geological section is as follows : 



Ft. In. 



1. Heavy sandrock (exposed) 30 



2. Shale 5 



3. Coal, Cumberland seam 2 



4. Clay, " " 1 



5. Coal " " 2 3 



On the farm of Henry Barnhardt, in section 8, in this township, a more 

 complete geological section was taken, as follows : 



Ft. In. 



1. Heavy sandrock, exposed 20 



2. Shale 1 



3. Coal, Cumberland seam 2 



4. Clay, " 8 



5. Coal, " 2 



6. Underclay 2 



7. Not exposed 48 



8. Limestone ; 2 



9. Sandy shale 20 



10. Limestone and magnesian limestone '. 5 



Bed of stream. (See Map XI., No. 25.) 



At other openings of the coal in this section the seam presents about 

 the same measurements as at Mr. Barnhardt's. The same coal is mined 

 along the banks of Fifteen-Mile Creek, in sections 7 and 9. In section 1, on 

 the land of Lewis Linchcomb, the following geological section was taken : 



Ft. In. 



1. Sandrock 15 



2. Shale 6 



3. Coal, Cumberland seam 1 8 



4. Clay, " 1 2 



5. Coal, " 1 3 



Near the south line of the township, in section 7, on Fifteen-Mile Creek, 

 I noticed many years ago a thin seam of coal, associated with a group of 

 limestones, about forty or fifty feet below the Cumberland seam. The
