all men and boys employed, 411 ; mules, 53 ; they shipped during the year
166,900 tons of coal, and used — kegs of powder and worked — days.
Ventilation is produced by the exhaust from the pump. These mines are
well ventilated. No. 3 is ventilated by a furnace, air circulating 35,000

cubic feet per minute at face of all the gangways ;
Machinery.—They use two mine locomotives inside ; they use 5 hoistingengines
of 200-horse power, 2 breaker engines of 50-horse power, 5 pumping
engines of 320-horse power ; in all 12 engines of 450-horse power ; they
have a brake on the drum at No. 1 but not on the other slopes ; they have
no speaking tube ; they have examined their boilers and reported the same
in safe and good condition; they have steam gauges on their boilers and
also safety-valves. The breaker machinery is fenced off for the safety of
the employed.
Hcmarks.— They liave furnished maps of their workings and reported all
serious accidents to persons ; thej' have no boj^s under twelve years of age
working inside. I have caused legal proceeding to be taken against three
persons for violation of section eleven of the mining law, for riding more
than 10 men at one time at these collieries. I deemed it proper to let them
go by paying the cost, as they pleaded ignorance of the law, and that it
had been a customary thing, promising never to do so again. Wm. S. Harris,
superintendent; A. Nesbit, mine agent.
Harleioh Colliery.
Situated two miles nortli of Ilazleton, on the estate of the Big Black
Creek Improvement Company, and operated by the Harleigh Coal Company.
It consists of 2 slopes and 2 breakers, and one slope kept for pumping.
Slope No. 1.—Sunk on the south dip of the Mammoth or E vein, a distance
of 461 feet; elevation at top of slope above mid-tide 1,518 feel, at
bottom 1,363 feet, thickness of vein 27 feet. In the south-east gangway
there is an inside slope of about 240 feet in length, driven across the pitch,
and the coal is hoisted to a level or bottom of the slope proper ; shutes
have been put in for the purpose of working the coal left in the upper
gangway. Those shutes extend from the bottom of the subterranean slope
to the upper gangway. A great deal of coal from the old workings can be
thus mined, and the company remunerated for their investments.
Ventilation is produced by the exhaust steam from the pump, and from
the heat of the s^am pipes which aftords the power of rarefaction. Slope
No. 2, which is now kept for pumping, is the intake and the slope being
the outlet. The air has been measured and reported according to law,
1,000 cubic feet at face of gangway, at outlet 25,000 cubic feet per minute ;
men employed, 68.
Machinery.—Thej' use 2 hoisting engines of 74-horse power, 1 breaker
engine of 24-horse power, 2 pumping engines of 120-horse power.; total
number of engines 5, of 21S-horse power. The}' have 26 steam boilers, reported
safe and in good condition. There is a brake attached to the hoisting
drum, and a car with bridle-chains expressly made for the men to ride
up and down the slope.
Remarks.—They have furnished maps of their mines, they have a prac-
tical mining boss, boys are not allowed to work inside under 12 years of
age, and they do not allow any person to ride on loaded cars. The parties
