Mr. Richard Vosper, at the mouth of Road Fork, mines the Cumber- 

 land seam, which is reported to be four feet six inches thick. 



JEFFERSON TOWNSHIP. 



This township borders Washington county, lying north and east of 

 Aurelius. Its outline is very irregular. The West Fork of Duck Creek 

 flows through a corner of it, but it is chiefly drained by Middle Creek. 

 The upper Salem, or Cumberland, seam of coal is found every where in 

 the hills, in its proper horizon. Valuable mines have been opened by 

 the Ohio Coal Company in the western part of the township, where the 

 lower and principal bench of the coal is from five and a half to six feet 

 thick, and the upper is reported to be three feet thick. A branch rail- 

 road extends from Macksburg east into this township, reaching this seam 

 of coal, where a working of six feet is obtained. The coal is of good 

 quality, well adapted to household use, to the generation of steam, and 

 to the rolling mill. A fine exhibition of the same seam of coal is found 

 on the land of David McKee, Esq , on Buffalo Run, east of Newburg, not 

 far from the line dividing this township from Enoch township. Here 

 the lower bench of coal measures six feet eight and a half inches. In 

 this region the hills are very high, and there will be found a large area 

 of available coal. The same seam is found in the eastern part of the 

 township, but it may not be equally thick. In the valley of Middle 

 Creek some petroleum has been obtained, although not in large quan- 

 tities. This is a fertile valley. 



Considerable petroleum has been obtained in the Duck Creek valley, 

 in this township, and more will be obtained when the prices render the 

 production profitable. Brine for the manufacture of salt may be ob- 

 tained by boring, and cheap fuel for its evaporation is abundant in all 

 the hills.
