The slope mine of the Southern Ohio Coal and Iron
Co.. which has very costly and elaborate arrange
ments for handling COAL has capacity of 600 tons per
day.
Two plans are followed in working the mine, one
by driving double entries. and the other by driving
single entries. Only those mines in which the height
of coal reaches four feet, work by the double entry
plan, and not all of them do The mine of the

mine and part of the workings of the Milton Furnace

a pillar to yards in width left between them,

In the Coalton district, instead of driving double
entries, wide entry is made, and the material

hauling roads. Is built mp side of the track
leaving hollow space next the pillar to serve
air-course. BY this plan saving is had in entry=
driving and the air is made to play along the entry
face at all times. AS temporary expedient this plsn
does very well, but after few months the loose
building of shale begins to settle and the air to leak
Where single entries driven, doors are placed
at the mouths of rsems and break-throughs made
between rooms as soop as they are turned, for the
purpose of getting forward air. These doors are
airtght at bestI they frequently left open
by the careiessness of he miners themselves and bad
air is found at the working faces of the mine.
The system of working with double entries, If sys-
tematic perfection in Ventilation desired is greatly
to be preferred single entry work. but the latter
method is cheaper than the former, and economy in
mining has too often the first claim upon the mana
gers of Mines against the health and comfort of
the miners.
In the majority of The mines of Jackson county the
undermining or holing is made on top of the ceal.

The main roads of mines are laid with 1T" Iron,

chiefly used in the yard coal mines and the 12pound
rail in the ourfoot mines. Wooden rails used in

The miners in the Coalton district paid cents
per more for digging than in the Welston dis
trct and Jackson the price in the latter districts
being the that of the great iron region of the
Hooking Valley. The prices ruling during the past
two years Wellston 80 cents in winter and 70
cents in summer. An average of 90 cents ton In
addition to the price of digging is required for the
payment of day that is haulers pushers, track
