feet from the Seven-foot vein, the Orchard vein 4 feet thick,
on dip
of 34 degrees south, 187 feet from the Primrose, and the Little Orchard
4 feet thick on 34 degrees south dip, 27 feet from the Big
Orchard vein, making the tunnel nearly 1,300 feet long from the
Seven-foot vein to the Little Orchard vein. An overhead return air
tunnel is being driven from the Primrose north to the Holmes, and
south from the Primrose to the Orchard.
/An air shaft 10 feet square
is being sunk from the surface, about 825 feet south of the new water
shaft, to ventilate the veins south of the Seven-foot. It was down
274 feet on December 31st.
Morea Colliery.—This colliery was idle from June 9th until Sep
tember 4th, during which time the principal part of the breaker was
rebuilt, over 400,000 feet of new lumber having been used. Most of
the old machinery was taken out and replaced by more modern appliances,
which has improved the preparation and increased the
capacity of the breaker. A tunnel has been driven on the slope level,
west of the shaft, 182 feet long from the north dip to the south dip
of the Mammoth vein, at the north end of which a plane is being
made to the surface. It is intended to strip the cover across the
basin west of this tunnel, taking the rock through the tunnel and
hoisting it up the plane to the surface. The Pennsylvania Railroad
Company is building a new railroad across the valley from the
Morea Station to a point a short distance west of the breaker so
that the coal under the present railroad can be mined. A tunnel
has been driven north from the north dip of the Mammoth, on the
slope level
east of the main tunnel 288 feet long, cutting the Skidmore,
Seven-foot and Buck Mountain veins on the north dip. A
tunnel has also been driven on the shaft Seven-foot level, north from
the Seven-foot vein north, dip 91 feet long, cutting the Skidmore and
Mammoth veins on the north dip.
Kaska William Colliery.—A tunnel has been driven south from the
Seven-foot vein opposite the bottom of the inside slope, cutting the
Holmes and Primrose veins on the south dip and the Primrose on
the north dip at the face of the tunnel. There is an interval of 188
feet between the south dip and north dip of the Primrose vein; in
this interval a diamond drill hole has been bored, cutting the
Orchard vein in the basin about 70 feet above the top of the tunnel.
The tunnel is 617 feet long from the Seven-foot vein, on the south
dip, to the Primrose vein, on the north dip. A tunnel 400 feet long
has been driven from the top bench gangway east of the top of the
inside slope to the Holmes vein on the shaft level for a return airway
for the slope to a new airway driven on the Holmes vein from the
shaft level 73G feet long to the bottom of an air shaft 05 feet deep
sunk from the surface. A 16-foot diameter fan was installed on
this new air shaft and the 24-foot diameter fan was moved from the
old airway and placed on the new air shaft. This fan is now being
