Trumbull and Mahoning Counties. In the southcentral part of 

 Trumbull and in the northcentral part of Mahoning County along 

 Mineral Ridge, the Sharon coal is reported to be accompanied by a 

 layer of black band ore which is doubtless the equivalent of the Sharon 

 ore of southern Ohio. 1 The ore varies in thickness from 6 to 10 inches 

 and overlies 2 feet of black shale; both the ore and the shale divide the 

 Sharon coal into two beds. Remains of the fresh water, bivalve crus- 

 tacean, Estheria, are said to occur in great abundance.
