Fergus County argus. [volume] (Lewistown, Mont.) 1886-1946, 1906-06-22

The deaths during the year totaled
1904. Compared with 1904, the total
fatal accidents shows a decrease O.
SIS, but the death rate has been in
creased by 1902. The death rate of the
underground workers at the mines
under the coal mines act in 1905 was
LAG per 1000 persons employers, as
against 1.34 in 1904; of surface work
ers O.75, against OBS in 1904. The
death rate of the under ground and
surface workers as a whole was 1876,
as compared with 1.24 in 1904. OF
persons under Is years of age the
death rate per thousand under the
coal mines act in 1905 was LIS per
under ground and 0.62 on surface; to-
tai, las, as against 1.39 in 1904.
The total number Of persons employ.
ed in and about all the mines of the
United Kingdom in 1905 was 887,524,
of whom S5S,373 worked at the 1882
mines under the coal mines act and
29,151 at the 688 mines under the
metalliferous mines act. Compared
with 1904 there is shown an increase
of 10,820 persons at the mines under
the cial mines act and a decrease OF
1858 employees under the metalliferous
mines act.
OF the 85S,373 employees under the
coal mines act, 91,112, or over 80 per
cent. were below ground, and of the
167,261 surface workers, $500, or 1854
per cent. were females. There is an
increase Of 416 females as compared
with 1904. Young persons under 16
employed below ground in these mines
were 1892. or 6.35 per cent of the
underground workers; the total num-
Der of surface and underground work
ers under Is was 6OO5S, or Z per cent
of all empliyes.
Under the metalliferous mines act
1926 persons, or over SO per cent,
worked below ground. and of the H.
1855 surface workers, 1856. or 100 per
cent, were females.
Employees under the quarries act
numbered 94,819 persons, Of whom
59,978 worked inside the actual pits
and 34,841 outside. Compared with
1904, there is decrease Of 2,271
among the inside workers and Of 487
outside, total decrease Of 2,75S. The
persons employed occasionally at
quarries are not included in these fig

An era Of closer milling has been
inaugurated in the Occur d'Alenes
practically simultaneously by the big
operating companies. They have prov
ed, after an exhaustive and costly SER
les Of experiments, that some Of the
mills have not been doing the most
economical wirk and that what is now
discharged from them in the shape OF
tailings or shines will repay a second.
airy treatment. This is not the case
at all the mills, as a number of the
larger plants near Wallace and Ward
ner are turning out very clean pro-
duct, and tailings above the slime end
of the mills will scarcely average one.

World. The attention to secondary
processes now in vogue in some OF
these mills has only recently been
considered necessary in several others.
The Morning Mine, near Mullan, pur-
chased by the Federal company some
few months ago, has one of the best
and largest mills in the district, but
they are now engaged in building an
addition which will house unit of the
CallOw system Of concentration, with
additional crushing and concentrating
machinery. The Callow unit will con-

with three sets of belt-screens for

of the travelling screens, will be treat
