962 GEOLOGY OF OHIO. 
The remaining outliers of the great coal of Monday Creek town- 
ship agree exactly with those already described. All are small, ranging 
from 1 to 5 acres. 
A single important outlier remains to be described in Gore town- 
ship. It is located in Section 35, and the furnace mine of the Thomas 
Iron Works is established in it. The original area of the coal was about 
120 acres. The first coal of the region successfully used in a blast 
furnace was the Baird coal, as has been already stated. This occupies 
an outlier, lying high and dry in the hill-top. It seems to have been 
held that these outliers were in some way best adapted to iron manu- 
facture, as the mines of three furnaces are located in similar outliers 
along this western outcrop of the great scam. Analysis of the coal does 
not show any adequate ground for such selection. 
In Green township there are found 7 outliers of the coal, together 
with the large body, also an outlier, that is situated between the Mon- 
day Creek and Hocking River Valleys. 
Four of the smaller areas are tributary to the Craft’s Furnace Mine, 
No. 13, C. & H.C. & I. Co. They are situated in Sections 11, 12 and 
5, and are already worked far towards exhaustion. Lying high in the 
hills, the cover of the coal is poor, and a great amount of timber is 
required to keep up the roof. ‘There is more than the usual danger in 
mining here. 
The structure of the seam in these outliers is shown in the follow-
