boys, in the slope; and I boss, 3 mechanics, 2 head and plate men, 7
breaker men, 2 drivers, 54 slate pickers, in all 150 men and boys. They
shipped 60,909^^;} tons of coal from this slope during the year ending December,
1875, and worked 130 days, and used 928 kegs of powder. Thej'
have 2 large and commodious breakers.
Ventilation is produced by the exhaust steam from the

Machinerxj in this slope and breaker consists of 1 hoisting engine of 120horse
power, 1 breaker engine of 25-horse power, 1 pumping engine of 150horse
power; total, 3 engines of 295-horse power, and 1 locomotive engine
inside, and 12 boilers, which have been cleaned and examined January 1,
1875, and are reported safe and in good condition. They have steam gauges
on the boilers and a brake on the hoisting drum.
Ileniarks.—They are making a map or tracing of the mines. There are
no boys under 12 j^ears of age working in the mines. They comply, generally,
with the requirements of the law. M. M. Cooper, superintendent

Situated three miles north of Ilazleton, on Porter's estate, and operated
by the Stout coal company.
Slope, No. 6.—Sunk on the north dip of the Mammoth or E vein a distance
of 294 feet to the basin ; vertical, — feet. The east side has not been
worked owing to the boundary line being so close to the slope. The west
gangway has been driven on the basin to the surface. The mining of the
coal is now confined to the stripping or patching of the same from the sur-
face. The coal is taken through a gangway to a point about midway in
the slope ; thence it is hoisted to the breaker. As the synclinal rises so
rapidly westward it would be very difficult to mine this coal otherwise than
the way as before stated, because the wash or the surface would cave in,
causing great loss of coal.
Slope, No. 7.—Sunk on the south dip of the Mammoth or E vein a distance
of 441 feet, at an angle of about — °, and is sunk to the basin. The
upper lift has been worked by the old Milnesville slope. There are two
gangways on the west side, one on each dip. The east gangway has been
driven considerable distance; and contains — breasts, which are opened by
a shute 7 feet long and about 9 feet wide to where a battery is erected to
prevent the coal from rushing too rapidly into the shule, &c., from which
place the breast is widened to about 30 feet, leaving ample pillar on each
side for the support of the roof. Cross-cuts are driven through these pillars
Vv-heuever required for the ventilation of the breastings. They emploj"
2 bosses, 35 miners, 35 laborers, 10 company men, 11 drivers, 2 door-boys,
in the mines ; and 2 bosses, 7 mechanics, 58 breaker-hands and choppers,
34 slate pickers; in all 196 men and boys. They shipped 66,000 tons of
coal during the yeav ending December 31, 1875, and used J, 160 kegs of
powder, and worked 265 days at the two breakers, which have a capacity
of about 800 tons of coal per day.
Machinery.—They use 3 hoisting engines of 180-horse power, 2 breaker
engines of 60horse power ; in all 5 engines of 240-horse power, and 4 steam
pumps and 21 boilers, cleaned, examined and re})orted safe and in good condition
December 25, 1875.
Ventilation is produced by the exhaust steam from tlie pumps, the slope
being the intake and the pump-way the outlet. The ventilation is good in
these mines, as there are good air-ways driven along the main gangway,
