feet forward into the vein of coal
from the bottom. After the vein has
been undercut its entire width in a
room or an entry the coal is blasted
out, and the miners load it into the
mine cars which are conveyed to
the foot of the hoist whence they are
raised the the tipple, weighed, and
dumped into the chute leading to the
box car leaders.
Power Plant.
The entire mine and it's workings,
both above and below the ground, is
illuminated by electricity, which fur
nishes power for all the machinery.
The power plant is located just east
of the Office building on the surface.
1t has two large dynamos one 100.
klowatts, and the other 50-kilowatts.
Plans are now being drawn up to en-
large the power house and install
third dynamo of $50 kilowatts, which
would necessarily mean more i'm
provements in the way of wiring, wat
er supply, etc. Electricity for the arc
lights and incandescent lights for the
city of Wilton is furnished from the
power plant at the Chaplin mine. The
installation of another dynamo will
double the present power and will
practically require double the space
of the present power house.
Mine Water is Used.
There are six boilers in the power
house, each 100 horsepower. Only
four are in operation simultaneously
two being cleaned and repaired while
the others are in use. Mine water
is used almost exclusively. Seven
electric pumps and two steam pumps
carry the water from the mine to a
large purifying tank in the power
house. Impurities in the mine water
are precipitated by means of chem
ical solution, and the purified water
is piped to another tank where the
exhaust from the engines heats it to
a temperature of about 125 degrees
before it is run into the boilers.
Locker and Bath Rooms
There is building for supplies and
the storekeepers office near the tip
pie, while the main Office building is
just north of the power house. Near
the incline entrance to the mine is
located the locker and bath house.
There are four hundred individual
lockers in this building, and two
changing rooms, where the miners
may change their clothing before and
after entering the mine. Shower
baths also afford the wOrkmen an op-
portunity to get rid of the dust and
CRIME that accummulates while they
are underground.
Re.arranein9 Shops
The carpenter shop, blacksmith
shop and electric shop are at the
present time under one roof. When
the addition to the power house is
built for the installation of the new
dynamo an extra wing will be con-
structed for the electrical shop eX-
clusively, and the space now occupied
by it will be divided between the
blacksmithing and carpenter depart
mentS.
Underground Stables
A barn for housing the thirty-five
mules used in the mine for hauling
cars in those sections where the troll
ley wire has not been stretched, is
located east of the power house. The
mules are sheltered above ground on
ly during the summer months, a ca.
pacious stable underground affording
them permanent quarters during the
winter. The underground stable is
complete in all details, there being
regular stalls for the animals, large
compartment for storing feed, a place
for shoeing the mules, and one of the
empty rooms" is converted into a
