on each side of the basin. Owing to the basin dipping west these gangways
are a considerable distance from each other. Before reaching the line to
work this coal another slope must be sunk. Air is good. An old breaker
attached to this slope took fire and burned down, together with two engine
houses, in the course of the year.
No. 6 slope, north dip. Length 440 feet. The coal worked in this slope
is the Wharton, of 9 feet thickness. The workings are nearly all on the
east side of the slope. There are two gangways, one going east, and the
other curving around the basin to south dip. The coal looks well, and is
of an excellent quality. This slope is ventilated by a furnace built in the
out-take. Air is good, about 7,000 cubic feet per minute.
Machinery of all the collieries consists of 6 hoisting engines, 230-horse
power ;
2 breaker engines, 30-horse power ;
2 pumping engines and 3 steam
pumps, 400-horse power; total engines, 13, 660-horse power; 30 boilers.
Men and boys inside, 135; outside, 139; total, 274; mules inside, 19;
outside, 21 ; total, 40. Coal shipped in 1873, 97,013|§ tons. Powder used,
2,041 kegs.

No. 1 slope, north dip, and No. 2, south dip. These are shallow slopes
to basin. They commence on a ridge in the vein, but further west the ridge
lowers down to a flat to bottom of basin, and the two basins join in a flat.
A gangway was driven from each slope, and met in the bottom basin, causing
all the workings to be in one. They have an excellent vein of coal,
which is the Big vein, of about 25 feet in thickness. The air is good.
No. 3 slope. Wharton vein ; thickness 9 feet. This is a new slope, and
the work is not all together opened out yet.
Machinery of all the slopes consists of 3 hoisting engines, 90-horse power
;
1 breaker engine, 20-horse power; total engines, 4, 110-horse power; 2
small steam pumps ; 7 boilers.
Men and boys inside, 59 ;

total, il. Coal shipped in 1873, 40,000 tons. Powder used, 1,000
kegs.

No. 4 slope, south dip. Length 450 feet. This slope is sunk in the
Mammoth vein ;
average thickness 50 feet. This is a large and extensive
work and well conducted. The gangways are very long on the east—about
one mile in length, and on the west side 1,200 yards. The pillars on the
west side have been taken out, reserving the gangway pillars to keep the
gangway up as an air course for the next lift, which the company is preparing
to open by sinking a small .slope near the bottom of the main slope
on the west side. Outside an engine has been erected to hoist from the
sinkers to the bottom of the present slope. The east side will be cut off
by a new slope sunk in No. 5 tunnel. The ventilation on the west side is
