regularly send out. The coal agrees in general character with the 
seam as already described. 
The mine of Poston and Company, which is next reached, is one 
of the oldest and best known of the field. Many of the descriptions 
already given apply to this property. It is, in fact, a piece of the same 
body of coal as that in which Brooks’ mine is opened, but the quality 
falls below the analyses quoted. The mine has a capacity of about 25 
cars per day. It has a long haul for its present production, and makes 
use of a mine locomotive in going through the hill. An analysis of 
the coal will be found on a subsequent page. 
Longstreth’s old mine comes next in order. This property is 
mainly worked out on the Hocking Valley side, and operations are 
suspended at the original works. The entries have been driven through 
to Monday Creek, and a large mine is operating there on the remainder 
of the coal. This mine is known as the Big Brier Hill Mine, or as 
No. 31, of the Columbus and Hocking Coal and Iron Company. It 
has a capacity of about 40 cars per day. 7 
A little above it, in the Monday Creek Valley, is the Little Brier 
Hill Mine, of Ricketts and Matthews. An analysis of the coal from 
this mine will be given on a subsequent page. 
Returning to the Hocking Valley again, we find the small mine 
of Hall and Dresback, No. 39, of the Columbus and Hocking Coal and 
Tron Company, working out a small block of coal belonging to the old 
Longstreth property. The mine is equipped to produce 6 or 8 tons 
per day. 
In the point of the hill that separates the valleys of the river and 
_ Monday Creek, near their junction, is situated the Maple Hill mine of 
W. A. Shoemaker & Co. It has a capacity of about 25 cars per day. 
The coal was mined in this hill for many years before the railroad 
was built, finding its way to market by the canal. The old workings 
were wholly lacking in system, and have left the coal in bad shape, as 
is found by present workings. In addition to this fact, the seam itself 
is considerably troubled and somewhat reduced at this point. The 
main entry of the present mine is in faulty coal for several hundred 
yards, and in the rooms the lower bench is often found reduced to 14 
or 15 inches, and the middle bench to less than 2 feet. The seam will 
not yield more than 5 feet of clean coal on the average. The quality
