MAHONING COUNTY. 799 
reliable coal seams. It probably makes its appearance in the tops of the 
hills east of Green Village, but if so it has very little cover and no 
value. 
Some of the more interesting local facts in the Geology of Mahoning 
county are given below in notes on the different townships. 
MILTON. 
This township lies so low, topographically and geologically, that none 
but the lowest coal seam can be found on any considerable portion of the 
surface. This has been sought for quite assiduously, and has been struck 
both east and west of the Mahoning. On the west side the basin is 
probably continuous with that of Palmyra. In the valley of the river 
Coal No. 1 outcrops, but is generally thin. Borings on the east have 
reached the coal in several places where it is of workable thickness. 
The following section of a boring on the farm of Jacob Helsel may 
be taken as a type of the structure of this part of the township where 
the coal occurs :

Coal No. 3 is found in the southeastern corner of the township of work- 
able thickness and pretty good quality, but rather tender. On the farm of 
Gideon Clingham, Coal No. 1 is reported to have been struck under sixty 
feet of cover three feet eight inches in thickness, but the statements 
made to me were so vague that it is doubtful whether the report can be 
accepted as reliable. The exact locality of the boring could not be ascer- 
tained, nor the elevation of the surface. The territory is not far from 
that, where Coal No. 3 is mined by Mr. Robbins, and it is quite possible 
that this was the seam struck. 
JACKSON. 
In the southwest part of Jackson township Coal No. 3 has been mined 
for some time on the farm of Frank Robbins. It is said to be three and 
one-half to four feet in thickness, but has little cover and is quite tender. 
This unusual development of Coal No. 8 extends southward into 
Ellsworth, where it is mined on the farm of Thomas Rose. In the south- 
eastern portion of Jackson, Coal No. 3 has been opened in several places, 
but it is of rather inferior quality. The coal opened on the farm of John 
Ewing, in the valley of the Meander, is the Briar Hill seam, Coal No. 1 ;
