though not copiously. The coal is of the same quality and thickness 
as that of the Star mine, and the floor promises to be equally irregular. 
This mine also discharges a little fire-damp. 
A switch has been built to the new shaft from the Horse Creek 
branch of the Ohio Southern Railroad, and the mine and furnace are 
thus connected by railway. | 
Raw coal is used in the Tropic Furnace in the reduction of ore, 4 
tons of coal being required on an average for every ton of iron made. 
This mine produces coal for the use of the furnace only, the daily pro- 
duct of the mine being 70 tons on the average. 
The Fulton Furnace, erected in 1868, is owned by the Globe Iron 
Company, and receives its supply of coal from the Globe slope, situate 
half a mile distant. This slope, which was sunk in 1865, hada blast 
furnace built in connection with the mine, but in 1876 the furnace was 
burned down and was never rebuilt, and the output of the mine has 
ever since been used for the supply of the Fulton furnace. The coal 
is hauled from the mine to the furnace by teams. None of the coal is 
shipped. 
The workings of the Globe mine are irregularly laid out, owing to 
the depressions and hills which forbid the adoption of symmetrical or 
systematic plans. The coal falls below three feet on the hills, and 
recedes to 4 feet in the swamp of the mine. 
The Huron shaft, which was sunk in 1875, supplies the Huron 
furnace with fuel. The furnace and shaft were finished at the same 
time; the depth of the shaft is 70 feet ; the coal is of the same general 
quality and thickness as the mines already mentioned. No coal is 
shipped from this mine, it being used exclusively in the furnace. The 
workings of the coal mines are suspended much of the time. 
The two shipping mines, the Eureka shaft and the Kyle slope, do 
not rely on any of the blast furnaces of the county for a market. The 
capacity of these mines is about 150 tons per day, but they could readily 
be raised to a capacity of 250 or 300 tons if the necessities of the coal 
trade required it. The coal in each mine is good, of the average thick- 
ness of the district ; it mines in larger masses; it is of inviting appear- 
ance, and as a furnace fuel, of good quality, but as a shipping coal the 
demand for this seam is limited. It contains too large a per cent. 
of ash to make it a favorite for house fuel or for the generation of steam 
so long as the finer grade of the Wellston or Coalton bed can be had at 
the same price.
