The registers of other borings made in this vicinity are given in the 
report of Prof. Stevenson on the geology of Carroll county. ) 
In Nimishillen and Washington townships, as the land is high, Coal 
No. 5 is generally buried beneath the surface. In Lexington township, 
however, on the north side of the divide, the tributaries of the Mahoning 
have opened the lower coais freely, and at Alliance Coal No. 5 lies ten 
feet below the station (five hundred feet above Lake Erie), and is worked 
in a‘shaft thirty-one feet deep, in the western part of the village. The 
coal is here three and a half to four feet in thickness, of fairly good 
quality, but, from the want of cover, rather soft, and contains consider- 
able sulphur. The roof is black shale, with iron ore, as in so many local- 
ities in Stark and Tuscarawas counties. 
The section at Alliance is carried down far below the surface by the 
shaft of the Alliance Coal Company. Combining the outcrops and sec- 
tions of the two shafts, we have the following geological column:
