GEOLOGY OF OHIO. 



From the Welsh bank I selected five samples for analysis : No. 1, middle 

 of top bench ; No. 2, upper part of middle bench; No. 3, middle of middle 

 bench; No. 4, lower part of middle bench; No. 5, middle of bottom 

 bench. 



Higher up the stream, on Rogers's Fork, near the north line of the 

 north-west quarter of section seven, Monroe township, the coal was found 

 to be twelve feet thick, in a boring made by Mr. Thomas Black. The 

 seam is about twenty-eight feet below the level of the stream. 



On the Middle Branch of Sunday Creek the same seam is also found in 

 fine thickness. At the Sands bank the seam shows the following struc- 

 ture : 



UT. IN. 



Shale, with plants. 



Coal, top bench 2 11 



Parting 1 



Coal, middle bench 5 3 



Parting 2 



Coal, lower bench , 2 10 



Analyses of seven samples representing the same seam, were made by 

 Professor Wormley, and published in his report in the Geological Report 

 for 1870. The average of the seven analyses is as follows :

The percentage of sulphur in the upper seven feet of the seam is only 

 0.53, per cent, which is quite small. 



Many test borings have been made at points where the seam is below
