806 GEOLOGY OF OHIO. 
WiLLow Bank Minz, No. 5. 
This mine is situated in Section 31, Jackson, and in Section 6, Perry 
township. It isa comparatively new mine, having begun its work in 
1881. It is producing 250 to 275 tons per day, and has been in quite 
constant operation. Its coal goes out by the Cleveland, Lorain and 
Wheeling Railway, with which it is connected by a narrow gauge track. 
The area of coal in this mine is estimated to have been originally 
30 to 35 acres. Its thickness is about 33 feet for an average. 
The roof is normally slate. Where the coal runs out, quicksand 
from the drift formations overlying, sometimes comes in, to the great 
damage of the mine. A seam of sandstone, 2 inches in thickness, 4 
inches above the bottom of the coal, extends over a considerable area 
in the mine, a fact that stands by itself in this field. 
The composition of the coal is shown in the following analysis by 
Professor Lord. ‘The coal was sampled by Mr. Frederick Keffer for 
the Survey:

Another body of coal of good promise has lately been opened by 
the Rhodes Coal Company, in Section 16, about 3 of a mile north of 
Willow Bank, No. 3. It is known as the Conrad mine. The area of 
this basin is thought to exceed 50 acres.
