sunk and a furnace built. There are two furnaces 6' X 6 ", 72 square feet
of fire-bed. On my last visit I measured 35,680 cubic feet of air goings
out at the outlet per minute and the distribution of this volume was all
rig-ht.
Smitldon No. 1 Mine.—An air shaft was sunk near the face of this
mine, the shaft is 9 feet in diameter and 100 feet in depth. There is now
a fresh current of air at the face of the workings, the average quantity of
air in circulation was 18,000 cubic feet per minute. They have also
built a self-acting incline plane on No. 34 heading to drop the coal from
the upper range of work to the parting on the lower main heading, from
there it will be taken out by a tail-rope sj^stem of haulage.
No. '2 Mine.—Is in fair condition with an average of 11,013 cubic feet
of air in circulation per minute. Mining-boss, Edward Bell.
Sirring Hill No. 2 3Iine.-—On June 4 I found the ventilation very de-
fective and what little air there was had to pass through a hole that I
could hardly crawl through, I ordered the hole to be cleaned out which
was done, increasing the quantity of air from 4,400 to 7,560 cubic feet
per minute, afterwards the company sunk a shaft 6 feet in diameter and
67 feet in depth and built a furnace; dimensions of furnace fire-bed 8' X 8',
length of arch 20 feet. On October 24 I measured 17.600 cubic feet
flowing out at the outlet per minute and this volume was fairly distributed
through the mine. Mining-boss, William S. Gibson.
Shaner No. 2.—The company has made some improvements this year,
first it has moved their hoisting engine in a direct line with the slojje
to make it of an uniform grade. I have found on my several visits that
the mine-boss kept the mine generally in a fair condition, with an average
of 24,000 cubic feet of air flowing in at the inlet per minute. The
distribution of this volume was fairly looked after. Mining-boss, Ruben
Street.
Madison Mine.—A new furnace was built at the mine this year. After
the furnace was built I measured on an average 17,753 cubic feet of air
in circulation per minute. This quantity can be increased bj^ keeping
a brisk fire in the furnace. Mining-boss, Martin Doyle.
The Soutlncesi Coal and Coke Company's Mines.
No. 1 "A" Shaft.—There were some important improvements made
inside and outside of this mine during the year. A duplex air compressor,
steam cylinder 12" diameter, air cylinder 14", 30" stroke for handling
the mine water, one battery of tubular boilers 60" diameter by 14' long,
a new brick boiler house, an air compressor room, and a new pump
house at the bottom of the shaft. The mine is kept in first-class con-
dition with an average of 72,645 cubic feet of air going in at the inlet
per minute. This volume is judiciously divided and circulated throughout
the mine. Mining-boss, John Duncan.
No 1 " B" Shaft.—Thiii mine is kept all right with an average of 51,-
