518 GEOLOGY OF OHIO. 
It must be remembered that: the larger part of the coal of the world is 
mined by means of shafts, sunk, often, to great depths. Here the sinking 
of shafts would involve comparatively little expense, and the coal could 
be brought to the surface directly upon the railroad. All the land would 
be underlain by the coal, thus saving a large area of coal which, when 
coal seams are in the hills, is lost from the erosion of the valleys. 
SENECA TOWNSHIP. 
This township of excellent land is situated in the northern part of the 
county, having Wayne township on the north and Buffalo on the west. 
Its north-west corner touches Guernsey county. It is drained by Wills 
Creek and its branches. A geological section was taken two miles west 
of Mt. Ephraim, which revealed the position of the coals and limestones. 
In no case were the coal seams opened so as to admit of measurement. 
The section is as follows:
