MASSILLON COAL FIELD. 781 
The Brewster Brothers’ Slope was a mine in the same basin with 
the mine last described. It was exhausted in 1882. In thickness and 
quality of the coal, it agreed entirely with the Middlebury shaft. 
The Thomas Brothers’ mine, otherwise known as the New York 
mine and the Old Sumner mine, is in an adjacent tract, originally 
including about 15 to 20 acres of coal, now verging to exhaustion. 
The coal of this mine is mined without powder. It is mainly 
“crop coal,” and is consequently weaker and freer in the joints than 
the rest of the seam, resembling the Mahoning Valley coal more than 
elsewhere. It mines small, and is used exclusively by the Middlebury 
potteries. 
The mine of the Brewster Coal Company, in Coventry township, 
has but a few thousand tons of coal left at best, and this mainly crop 
coal of inferior quality. The mine is a continuation of Brewster 
Brothers’ Slope, already noticed. The face of the coalis N. 50° EK. The 
seam runs as high as 6 feet in some of the swamps, but it averages 
about 4 feet. It is not generally worked below 2% feet. This coal finds 
its way to Lake markets exclusively. 
On the line dividing the Brewster Brothers’ coal property from the 
Brewster Coal Company’s land, a deep hole was drilled in 1882, the 
depth of which was about 800 feet, at the time that the following record 
was obtained :

The identifications are made by the Survey, but they will scarcely 
be called in question by any geologist, corresponding as they do with 
the sections of the outcrops everywhere. The conglomerate has an 
excessive thickness, but this formation has no normal measurement. 
The Lake View mine is one of the larger mines of this section, its 
daily output being 225 to 250 tons. It is operated by the Lake View 
Mining Company (Todd, Stambaugh & Oo., of Youngstown). It is 
connected with the Valley Railway by a branch line. 
On the land of Charles Switzer, which holds part of the coal of 
this mine, the following section is found:
