I. COAL MINES OF MAHONING COUNTY. 
The Block coal field of Mahoning county is one and the same with 
the Trumbull county tield, and can be described to the best advantage 
in the present connection. 
There are four townships of the county that are known to contain 
the Sharon seam of workable dimensions, and in considerable area, viz., 
Youngstown, Austintown, Boardman, and Poland. The first two adjoin 
Liberty and Weathersfield townships, respectively, and the Youngstown 
coal agrees in all respects with the Liberty coal, while the Mineral 
Ridge field of Weathersfield township extends into Austintown, and has 
an important part of its development there. This last named field will 
be first taken up. 
There are nine mines now in operation in the Sharon seam in Aus- 
tintown. They all contain the coking or Mineral Ridge coal. Several 
of them hold good developments of Blackband, and two of them con- 
tain the Block coal as well as the coking seam. The mines are as

Several of these produce excellent furnace coals, as the Pennel, 
Jordan, and Fool’s Errand, and all of them yield a good milling and 
domestic fuel. As in the townships to the north of them, most of these
