162 ANNUAL REPORT OF THE
about 69°. This part of the mine is now abandoned, except the v/est i-(M
ash gangway, which continues to be worked. The cast red ash gangway-
is driven 5,500 feet, to where a tunnel 310 feet long cuts the big vein tiie
second time. The east gangwa}' of the tunnel has been driven 6,591- feet
and struck the basin.
Slope No. 7.—Height above tide at top of slope, 1,464 feet ; at bottom,
913 feet; vertical, 551 feet. This slope is located about 5,500 feet east of
slope, No. 4, and sunk on the "Crack" vein, which is about 3 feet thick,
the balance being driven through rock 290 feet to a level with tunnel, No.
5, gangway ; thence 265 feet to the bottom or level of slope, No. 4, gangway.
At the level of No. 5 tunnel and the level of ISo. 4 slope a tunnel is
driven from the "Crack" vein (on which the slope is sunk} to the big vein.
The coal is hoisted to the level of No. b tunnel ; thence is taken by the locomotive
engine through tunnel, No. 5, to the breaker, a distance of 1^
miles. The east gangway in slope, No. 1 (or a continuation of the old
,
east g;angway of slope, No. 4) has been driven 1,700 feet east of the slope,
with 21 breasts opened. The vein proved very irregular, as they went
east, but proves very encouraging at present in the face. The vein thinned
out to about 6 feet in some places, and at the face or heading 18 feet ; and
the coal good. The timbering which has been d.onc in this slope is extraordinary.
They employ 1 boss, 84 miners, 28 laborers, 69 company men,
17 drivers, 6 door boys, in the mine^ ; 1 boss, 11 mechanics, 13 plate men,
28 breaker hands, 7 drivers and 44 slate pickers, in all 309 men and boys.
They shipped during the year 50,124 tons of coal, and used 720 kegs of
powder.
Ventilation.—This is produced by 2 fans, each 16 feet in diameter, and
connected on the same shaft The air is conducted system.atically to the
face of the works. The ventilation has been measured and reported 85,000
cubic feet per minute ; men employed, 184.
Machinery —There is 1 locomotive engine hauling the coal from inside
to the breaker. They use 3 hoisting engines of 60-horse power, 1 breaker
engine of 65-horse power, 1 pumping engine of 51-horse power, 2 fan
engines of 20-horse power ; total number of engines, 7 ; aggregate horse
power, 196.
Remarks.—The machinery of No 7 slope is on the surface. They are
putting a brake and flanges on the drum. They have had their boilers
cleaned and examined and reported according to law. John Davis, Esq.,
is master mechanic, and has charge of all the machinery about the mines.
He is a gentleman of ability and lives up to th» requirements of the law.
Geo. Holvey, general inside foreman ; William Evans, mine boss ; William
Eatcliff, outside foreman.
Tunnel, No. 6, and Slope, No. o.
This tunnel is located on the north side of Panther creek, on the estate
of the Lehigh coal and navigation company, and operated by the Lehigh
and Wilkesbarre coal company, and is 1,072 feet above meaji tide at tunnel's
mouth.
This tunnel is 600 feet long, cutting the Red Ash vein ; thence 350 feet,
catting the Mammoth or E vein on the south dip, at an angle of 43°. At
the head of this tunnel is where the fire originated August 12, 1871, and
v.'here the slope is sunk which is now abandoned. The company finding
the coal becoming scarce in the water level workings deemed it expedient
to make some further developments by re-opening the old slope. But finding
the vein on fire the project had to be abandoned. The red ash gangway
is 3,300 feet long to Shield's tunnel, which is 350 feet, cutting the
