the loose coal in the old breastings ; 7 steam engines are in use==450-horse
power ;
22 steam boilers are in good condition

No. 21.
Diamond Drift.— Messrs. Motzs & Berluchy, Operators.
This colliery is situated near Wadesville, on the estate of the Philadelphia
and Reading Coal and Iron Company. It consists of a drift opened
on the J seam, north dip 50°. The drift is 500 yards long, in fault, and
idle. Nine breasts are working in 6 feet of good coal, flanked by 7 yard
pillars. The north dip gangway is 89 yards long, and ends in a fault.
Twentjr-five hands are employed in and about the mine.
Ventilation is produced hy natural currents, which proved inadequate to
supply proper ventilation.
One 10-horse power engine runs the breaker ;
one boiler in use ;
the
machinery and breaker attachments are secured against accident ; no deaths
or injuries took place during the year; 8 visits of inspection had been
made.
No. 22. Glentworth Slope.— James G. Oliver, Operator.
The colliery is situated at Eagle Hill, on the estate of the Philadelphia
and Reading Coal and Iron Compauy. It consists of a double track slope,
sunk 210 yards deep on a 30° south dip on the G seam. The east panel is
700 yards long, with 8 breasts, &c, working in 9 feet of Red Ash coal.
The western panel is 650 yards long, with 7 breasts, working in 12 feet of
coal. The top state is not secure to mine large panels, as it is generally
soft and slaty. I recommend the improvement that has been made in the
mine for its workmanship and safety.
Ventilation is effected by the action of a 40-horse power fan. The air is
conducted to the face to the working places, thence traverse them to the
out-cast on its return. The air doors are properly adjusted and the mine
generates a considerable amount of gas, and it is necessary to use safety
lamps and employ a fire boss.
Colliery Log.— 135 hands are employed in the colliery ; 8 mules and 26
wagons worked; outside temperature, 73°; inside temperature, 76°; difference,
