access. Fortunately, near Steubenville, quite a large body of it has 

 escaped erosion, so that a number of banks have been opened near each 

 other to supply the city. The northern limit of the coal is on the south 

 side of the pike, leading directly westward from the city. The full sec- 

 tion obtained here, beginning at the coal banks, two miles from the Court 

 House, and descending ^o the creek, is — 



1. Shales, inolading flaggy limestone 50 feet. 



2. CoalNo.lO 1 " 



3. Shale and sandstone 60 "

5. Clay and shale 25 " 



6. Limestone 2 to 4 feet. 



7. Shales and flaggy sandstone 190 feet. 



8. Crinoidal limestone 4 to 6 feet. 



9. Shale 25 feet. 



10. Coal 1 foot to 1 foot 3 inches. 



11. Shale — argillaceous above, arenceons below 70 feet.

At Mingo, nearly five miles south from Steubenville, five feet of lime- 

 stone were seen above Coal No. 8, but no limestone was sfeen at that hori- 

 zon elsewhere. 



At Mr. McCune's bank, the coal gives the following section :

The thickness of the roof coal is given on authority of Mr. McCane. 

 It was not seen. Though not mined, it is said to be a good coal, but to 

 leave a bulky while ash. No. 7 is a beautiful coal, burning very freely, 

 with but little tendency to cake. For about one foot above the parting, 

 No. 3 is equal to No. 7. No. 5 is very good, but soft, and is the "bearing-
