The volume of the coal is good, but its quality is poor, as indicated 
by the following analysis :

The coal is short grained or curly. It is not easily mined, and the 
middle slate makes it very dirty. It is used only because of its accessi- 
bility, and it cannot hold its place where other coals compete on any- 
thing like equal terms. It is to be noted that the Baker bank is the 
only one in Northern Ohio in which this seam is at present worked. 
The seam is shown in many sections, but it attains its greatest thickness 
here. In Sugar Creek township it has been mined in years past, but is 
no longer worked. 
THE BROOKVILLE CoAauL (Coat No. 4 or NEWBERRY). 
The Brookville coal is worked at several points in the county in 
connection with its overlying limestone. The best development occurs 
in Dover township. The section found on the farm of William Swaby, 
in lot 30, has been already given (see Fig. XIX, B.). This section is 
prodigal in the display of the mineral wealth that belongs to this por- 
tion of the series. It contains two coal seams, two limestones, two 
horizons of iron ore, and two of fire-clay, that are all worked at the
