and eighth right headings, also in the eighth and ninth left headings,
rendering the use of locked safety lamps necessary. Another tail
rope haulage has been put in fourth left heading.
Eleanora No. 1.—This mine is in good condition as usual. All
parts of the workings were, at the time of my last visit, well supplied
with fresh air. Quantity of air passing at the outlet, 75,000 cubic feet
per minute.
Eleanora Nos. 2 and 3.. .The general condition of these mines has
been very good duriug the year. Ventilation is produced by a twentyfive
foot fan. The average volume of air passing at the inlet per
minute was 100,000 cubic feet, which was being well distributed
throughout all the workings. The large output of coal at this mine
is practically all mined by mining machines of the Ingersoll and Harrisan
type. They have in operation thirty-seven of these machines,
which are equal to seventy-four in effect on account of being run day
and night. At the No. 2 mine boilers have been erected on the line of
the main slope, about 3,000 feet from the main entry, which are now
pumping the bulk of the water through bore holes at that station.
They have also increased the trackage room, both above and below the
tipple. A tail rope haulage system, about 3,000 feet long, has been
put in, thirty-four new coke ovens and fifteen houses for the workmen
have also been built.
Beechtree No. 3 Mine.—When last visited the ventilation and
drainage in parts of the mine required improvement.
Beechtree No. 2.—This mine has been in operation only about onefourth
time duriug the year. I measured 65,000 cubic feet of air per
minute at the outlet, which was being distributed throughout all the
workings.
London Mine.—This is a large mine employing a great number of
men. Mining machines are used to undercut the coal. Blasting
operations are carried on very extensively, and it requires very brisk
air currents to clear away the powder smoke as fast as it is produced.
The two small fans now in use are not suflicient for the work refpiired,
and they should be dispensed with and a more powerful one provided.
The quantity of air in circulation when last examined was 40,500
cubic feet per minute, which was being fairly well distributed
throughout the workings.
Clarion No. 1.—Tliis mine is
in good condition, both as to ventilation
and drainage.
Clarion Nos. 2 and 3.—Are in good condition in all respects.
Clarion No. 4 was opened in the early part of 1896. It has two
openings, one on each side of the hill, the outside haulage being by
two steam locomotives and the inside haulage by mules. It is intended
to instal machine haulage, either by ropes or electricity, in the
near future. They commenced loading coal for the trade on January
