by a party of drillers who were boring for salt. A local shaft was put 
down to test the thickness and quality of the coal. It proved to be 4 
feet thick, to belong to the dry-burning family of coals, and it soon 
attracted the attention of capitalists, among whom was the late Gov. 
David Tod, of Brier Hill, from whose farm the famous Brier Hill coal 
of the Mahoning Valley derives its name. Mr. A. 8S. Kyle, of Youngs- 
town, was one of the first to pronounce favorably upon the iron-making 
qualities of this coal. 
The Jackson Shaft coal extends through portions of Lick, Coal, 
Liberty, Scioto and Hamilton townships, in an irregular line, for a dis- 
tance of 15 or 16 miles, its width varying from } mile to 4 or 5 miles. 
It is disposed on a very irregular floor, and is frequently wanting where 
it is due. It is met above water level in each of the above townships, 
but is nowhere mined with vigor, except in the township of Lick, fin 
and around the village of Jackson, the county seat. 
There are 6 mines in operation in Jackson, all shafts or slopes, 
varying from 40 to 90 feet in depth. The coal varies from 3 to 4 feet 
in thickness, and is mainly used in the blast furnaces of the district. 
Four of the mines have blast furnaces erected in connection with the 
shafts, and the coal from two of these mines is delivered directly from 
the shaft into the furnace stock-house. ‘Two mines rely exclusively on 
shipping for trade. The following are the names .of the mines, together 
with the names of the operators of the same:
