844 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-

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 
0.58, per cent. which is quite small. ; 
Many test borings have been made at points where the seam is below
