MAHONING COUNTY. 799 • 



reliable coal seams. It probably makes ita appearance in the tops of the 

 hills east of Green Village, but if eg 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 Hotes 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 beea 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 Talley 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 :

i. Surface deposits 45 



2. Sandrock 35 



3. Dark gray shale 7, 



4. Light gray shale 6 



5. Eeddishshale 1 



6. CoalNo. 1 3 :J 



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 ia tkickness, 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. Bobbins, 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. 3 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 r-ather 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 ;
