494 REPORT OF THE INSPECTORS OF MINES. Off. Doc.
Douglas Slope.—This mine adjoins the above mentioned, and is on
the same vein and the general plan of working is the same. They
worked only a part of the year, and the ventilation was found to
be good at the different visits made to the mine.
Harts.—This is a small mine and only during the winter months
for a short period does it come under the provisions of the law, but it
was found in very fair condition whenever I have visited it.
Forest.—This mine adjoints the Kyler mine, and in some portions
the two mines are cut into each other, and the same thickness of coal
and general characteristics prevail as at Kyler. They have a great
deal of trouble with faults in this mine, there being several small ones
and then a big one throwing the coal down in most places twenty-six
feet, so that it will be necessary, at some future time, to get an opening
behind the fault so as to win the largest portion of the coal in the
property. They did not work very much during the first part of the
year, but on each visit the ventilation of the mine was good. They
Lave done little work in the new opening, and at my last visit they
transferred the miners into No. 1 mine.
Winburne.—This mine is located one mile from Winburne station,
on the Beech Creek railroad, and has worked fairly well during
the year. The ventilation and the drainage were always
found in good condition at the visits made to the mine. They have
started work in a mine that was stopped several years ago on account
of its
going to the dip, and they took in a big lift of bottom so as to
get as near the bottom as they possibly could, and now they are opening
up the mine as fast as possible. They have made connections with
the mine where the fan is located and after awhile the fan will be
located at a more convenient point than at present. This is the same
vein and the same method is followed as at the mines at Munson.
(xrass Flat.—There are four mines, Grass Flat, Knox Run, Moravian
and Pleasant Hill, all located on a branch road, which leaves
the Beech Creek railroad at Viaduct station. The vein and general
characteristics are the same as the mine last mentioned. The Grass
Flat mine is the largest and also the oldest mine of the four, and
the coal is hauled out by the tail rope system, and the present length
of the haulage is nearly one and a quarter miles. The ventilation and
the drainage were very good during the year, and things are well
looked after.
The}^ have much trouble with water, so they have, for
years, been following the workings with a water level which has so
far enabled them to drain Ihe mine without steam power. The fan
used for ventilation also ventilates the Pleasant Hill mine.
Pleasant Hill.—This mine adjoins the last mentioned one and the
same characteristics prevail hcic. The ventilation and drainage
were very good during the .year. The workings on Ihe south
side of the main heading go (o iIk^ dip foi- a poi'tion of the dis-
