Slopes, Nos. 1, 2 and 4, as previously reported, are all abandoned, and
are now drowned and the coal worked out.
Slope, No. 5.—Sunk on the south dip of the Mammoth or E vein a distance
of 390 feet to the basin, at an angle of about 45° ; perpendicular
depth, 276 feet. The basin dips from east to west. A new slope has been
partly driven west of the present slope in order to sink another lift belov,the
No. 5 gangway. The east gangway has been driven to the boundary
line, with 20 places worked ; consists chiefly in robbing pillars. The west
gangway is driven quite a distance, and is about surmounting the anticlinal
into the north dip of the same vein. A tunnel has been driven on the west
side of the slope, cutting the Wharton or D vein on the south dip, and gangways
turned olF east and west of the tunnel. The east gangway has been
driven 1,140 feet, with 35 breasts opened. The west gangway has been
driven 1,320 feet, with 37 breasts opened. The vein is about 9 feet thick;
coal very good quality. There are 105 mine cars, with a breaker capacity
of 400 tons per day. A new breaker is now being built to take the place

Ventilation is produced by means of exhaust steam from the Thatcher
pump, the manway being the inlet and the pumpway the outlet. The air
in the Big vein is favorable, but in the Wharton it has been very unsatisfactory.
I have given orders to have the same improved forthwith. The
following is the report of air measurements for month of December : Intake,
11,000 cubic feet per minute; outlet, 12,000 cubic feet per minute;
