84 ANNUAL REPORT OF THE
feet deep of a shaft is sunk from the surface to the saddle of the 7 feet seam
for an outlet. Work at present is chiefly confined to extension of gangways
and repairs, &c.
Ventilation is produced by natural currents caused to circulate through
the working places in separate spits, and traverses to the slope.

Forty-three hands are employed in the colliery ; 6 steam engines are in
active^service=730-horse power ; 2 pumps, one a 16 inch and one a 6 inch
steam pump ;
14 steam boilers, whose condition has not been reported ; 10
mules and 31 wagons are worked.
Remarks.—The breaker had been destroyed about a year ago in consequence
of which shipments and general mining were suspended, and probably
will not be resumed until spring.

The colliery is situated west of New Castle, on the estate of the Philadelphia
and Reading Coal and Iron Company. It consists of a single track
slope, sunk 60 yards deep on the escarpment of the E seam, on its northern
dip. Its gangway is opened 250 yards, with 5 breasts, working in 60 feet
of coal, and another gangway is opening south of the 7 feet seam, all of
which workings are in good sale condition.
Ventilation is here produced by action of the natural air currents traversing
the working places, and chiefly governed by the action of the atmosphere.
Powder smoke is a troublesome agent in the mine.

Thirty-two hands are employed in and about the colliery ;

4 steam boilers (good) are in use.
No map of the colliery had as yet been furnished. 60U yards of track
has been laid. This place has onby recently been opened, and bids fair to
become a remunerative colliery in a short time. Mr. Davis being a practical
man in mining and mine management.

The colliery is situated a short way west of Wadesville, on the estate of
the Philadelphia and Reading Coal and Iron Company. It consists of a
double track slope, sunk 110 yards deep on a 23° south dip of the F or
Primrose seam. 900 yards of a western panel has been opened, with 9
breasts working in 8 feet of good coal. 100 yards of an east gangway is
opened, and 2 breasts working in 12 feet of good coal. The mines are
poorly ventilated. Powder smoke prevails to a troublesome extent.
^Ventilation is effected chiefly by the action of a 6 horse-power fan, which
in fact has but very little effect.

presence of a mixture of flre-damp in the air current, which had, in fact,
no current at all.
