THE LOWER COAL MEASURES. 287 
Liberty townships. It yields but little coal, so far as known, in Wheel- 
ing township, but in Liberty it gives rise to numerous small mines. 
The most northerly of these banks is that of Joseph Proctor in section 
22, one mile east of Kimbolton. The following elements are shown in 
ascending from Wills Creek Valley :

The seam is here apparently split, as at numerous points in Tusca- 
rawas county. The two openings are not directly over each other, and 
the interpretation may be changed by further development, but the view 
given above seems the true one, as the facts now appear. Both seams 
have been worked, but the lower one only is mined at the present time. 
The quality of the coal is fair, as judged by the testimony of those that 
have used it, and by the appearance of the entry. In going southward, 
the occurrence of mineable coal at this level becomes more frequent, 
though still there are many points at which clay and limestone and 
black shales are very conspicuously displayed, without any coal being 
present, or else with a seam too thin to be mined. At Broom’s Salt 
Works the coal was opened, showing but 16 inches in thickness. On 
the west side of Wills Creek, in section 24, Cambridge township, on 
the old Sarchet farm (now Ford’s) the seam has been mined for a num- 
ber of years. |
