136 ANNUAL REPOKT OF THE
Drift, No. 2.— Driven on the same vein. JMeasured from center of slope :
Extension in eastern direction, 2,191.5 feet; extension in western direction,
1,673 feet. Not working at present.
Slope, No. 2.—Sunk on tlie south dip of the same vein, and is 451 feet
long; average pitch, 28° ; perpendicular depth, 212 feet. The east gangway
has been driven 618 feet, and the extension in western direction 339
feet. This js a new slope and has l.< en discontinued until the new breaker
is ready, and also the completion ot the new transportation lailroad now
under construction by the Central L'ailroad of New Jersey, Lehigh and
Susquehanna division. The breaker is large and commodious, well adapted
for the preparation of the coal mined lu the Buck Mountain vein. Great
improvements are now being made in and about the mines, and the condition
of the same is commendable.
Ventilation is produced by a 16-feet diameter fan, and another fan 16 feet
in diameter is being built to ventilate the other dip. Air circulating 28,-
900 cubic feet per minute. Men employed, 139. When I first visited this
mine the air was inadequate for the support of the men. But when I made
it known to the operator he immediately ordered the erection of. those f;ins
before mentioned, and now the ventilation is very satisfactory.
Machinery.—They use 5 hoisting engines of 160-horse power, 1 breaker
engine of 30horse power, 2 pumping engines of 350-horse power, 2 fan
engines of 80-horse power, in all 10 engines ; aggregate horse power, 620 ;
and 12 cylindrical steam boilers, which have been cleaned, examined, reported
safe and in good condition.

1875, and used 1,360 kegs of powder, and worked 124J days. Breaker
capacity, 750 tons of coal per day pumping capacit^^, 8,280 tons of water
;
per 24 hours, equal to 2,229,793 gallons of water in the same time, reckoning
36 cubic feet to the ton. Arthur M'Clella!), superintendent; E. L.
Powell, mine agent.
Highland Collieries.
Located 9 miles noith-east of Hazleton, gn the estate of the Highland
Coal Company, and operated by G. B. Markle & Co.
Slope No 1.— Sunk on the south dip of the Buck Mountain or B vein, a
distance of 753 feet, at an angle of about 30°. The east and west gangways
proper are now being robbed of pillars. About 285 feet west of the
bottom ot the main slope is wherc another inside slope has been sunk 240
feet long, at an angle of about 15°. The most of the work is done on the
east side, the vein is about 15 feet thick, the roof is good and the coal is of
a very good quality. The breasts are opened 30 feet wide, 18 feet of pillar
reserved for the support of the roof.
Ventilation is produced by the exhaust stearn from the pump. The slope
being the intake and the pumpway the outlet ; air tolerable, 17,050 cubic
feet at face of gangway, per air report for November.
Slops No. 2 is a new slope lately sunk on the north dip of the Buck
Mountain or B vein, gangways are now being turned off east and west of
the slope. The coal is good, and an excellent roof as far as can be judged
from the part of the work which has been opened. They are now building
a now breaker to prepare the coal mined from this new slope. They eniploy
at both places: One boss, 60 miners, 5 laborers, 2 company men, 13
drivers, 2 door boys, in the mines ; 1 boss, 6 mechanics, 23 breaker men, I
