156 ANNUAL REPORT OF THE
The top of the slope is feet above mean tide, and at the bottom of the
same feet, and is sunk to the basin. The west gangway has been
driven 1,900 feet, with 43 breasts worked out, and the east gangway 390
feet, with 8 breasts worked out. The bottom lift is about being abandoned.
A counter gangway is now being driven over the slope to work the crop
coal.
Slope, No. 2.-—Sunk on the south dip of the Wharton or D vein a distance
of 780 feet, to the boundary line of the New York and Lehigh Coal
Company's property, at an angle of about 9|° ; vertical, 130 feet; elevation
above mean tide at top of slope, feet ; at the bottom of the same,
feet. The west bottom lift gangways consists of robbing pillars on
the east side. The east counter gangway has been driven 1,000 feet, with
17 breasts opened, and the west counter gangway 3,4G0 feet, with 68 breasts
opened, and the most of them worked out. The vein is about 9 feet thick,
and the coal of very good quality. Also an excellent roof. This slope is
worked by a single track, owing to the counter gangways.
Ventilation is produced b^^ a furnace on the west gangway, and by natural
causes on the east. On i!iy first visit to these mines the air was inadequate
for the support of the men. Since a very good furnace has been
built, causing sufficient ventilation ; 14,770 cubic feet per minute at face
of gangway, per report for November.
Slope, No. 3.—Sunk on the south dip of the Wharton or D vein a distance
of 154 feel, at an angle of about 30° ;
elevation above mid-tide at top of slope,
perpendicular depth, 75 feet ;
feet ; and at the bottom of
the same, feet. The east gangway has been driven 450 feet, with 10
breasts opened. The w^est gangway has been worked 150 feet, with 8
breasts worked out. The present workings are all on the east side, and the
gangway has not far to go to the boundary line. The ventilation tolerable :
5,700 cubic feet in face of gangway, per air report for November ; men em-
ployed, 7.
Slope, No. 4.—Sunk on the south dip of the Wharton or D vein a dis-
perpendicular depth,
tance of 660 feet to basin, at an angle of about 34|° ;
370 feet ; elevation above tide at top of slope, feet ; at the bottom of
the same, feet. This is a single track slope, adapted for the counter
gangway system. About midway in the slope there is a counter gangway
driven west for a considerale distance through rock, as the vein pinched
out, but is now in good coal about 9 feet thick. The east gangway in the
bottom lift consists of 9 breasts, and has been worked to the boundary line,
and is 460 feet long. There are 2 gangways on the west side of the slope,
1 on each dip. The gangway on the south dip is 420 feet long, and contains
8 breasts working. The roof is good and the coal of superior quality.
The mode of working is considered safe.
Ventilation is produced by the exhaust steam from the pump, the manway
being the inlet and the slope the outlet. This slope is partitioned off
by boards, aftbrding an outlet for the steam. Owing to the leakage of the
brattice it makes it very disagreeable on the slope. The air circulates
down the man-way ; then to the face of the south dip, west gangway j
thence through the cross-hole to the north dip, west gangway; thence to
the east gangway, and returning to the outlet. The air on the west side
is very good, but on the east side is not very commendable. I was obliged
to stop some of the workings on the east, owing to the defective ventila-
tion. Provision are being made to improve the same on the east side.
Measurements taken in face of west gangway, 12,600 cubic feet per minute
;
men employed, 62.
