804 GEOLOGY OF OHIO. 
36, but the coal has been mainly worked out. It originally held about 
60 acres. The mine was first opened in 1871, and has yielded a large 
amount of excellent coal. It is now producing 275 to 300 tons per 
day, mostly pillar and crop coal. The shaft is located at about the 
center of the basin, and is 140 feet deep. 
The coal has been followed as low as 18 inches, but it reaches the 
usual average of 4 feet in all of the main workings. The mine has a 
good roof, better, in fact, than the average. The product of the mine 
is shipped by the Cleveland, Lorain and Wheeling R’y, with which it 
is connected by a side track. 
A number of exhausted mines are found in this township, some of 
which have been largely productive and profitable. Among them are 
the Aberdare shaft, the Crawford slope, the Crawford shatt, the Staeffer 
mine, the Willow Bank mines, Nos. 1 and 2, and the Burton Furnace 
Company’s mine. 
To this list, most of the mines already described, will soon require 
to be added. But few have any large acreage before them. 
All of the mines above named, and several of those that have 
been previously described, constituted, in reality, one almost continuous 
field, by far the largest and most valuable of the entire district. The 
Willow Bank Section of this field must have aggregated 200 acres, 
taking in the Willow Bank, Mountain, Burton Furnace and Clark 
mines. 
MINES OF JACKSON TOWNSHIP. 
There are three mines of the Massillon coal now open in this 
township, viz., the Willow Bank, No. 3, or “Ground Hog mine”, 
Willow Bank, No. 5, and a new mine opened in Section 16. These 
will be briefly described. ‘To them may be added an abandoned mine, 
formerly known as the Bridgeport mine. 
Tue GRouND Hog MINE. 
This mine is situated in Sections 19, Jackson, and 24, Lawrence 
townships. There are under lease, to the Rhodes Coal Company, 280 
acres, but less than 100 acres hold the coal. Like the mines already 
described, this one has been worked almost to its limits. Most of the 
coal now yielded comes from pillars, and at the furthest it will be kept
