a current of air through flue to

currents of air until all dust and
fine particles of rock are disengaged
and the fibre, settling back, is TAX
en- up and delivered to the revolv-
ing screen which automatically
grades and divides it into four or
five different grades necessary to
the requirements of the asbestos
goods manufacturers.

Wyoming Asbestos Cheap to Mine.
Mill, and Market.
According to figures from the
Canadian operators the cost Of pro-
duction in that field is $17.41 per
ton, but it can be produced in Wyo-
ming fields for much less.
Some very important freight rate
reductions have been obtained from
the roads entering the Wyoming
fields and it is now impossible to
ship to many different points and
meet the sharpest competition with
out in any way sacrificing profit.
AS the work progresses at the
mines the cost of production is con-
stantly being cut down: but expen-
sive experiments are being carried
on at the Denver grinding plant to
find additional uses for the very low
grade rock, so that there will be lit
tie or no waste. 1t Is expected that
in the very near future some use will
be found for every pound of material
removed from the pits.
The Northwestern Company has
erected a three hundred ton capa-
city mill on their property, and by
early spring will be in full running
order.
The International company have
a mill and it is in active operation
a success in every way, modern and
up to date.
H. Leslie Parker is in charge Of
operations at the mines and mills
and he is an experienced operator
practical in every way, having fol
years been connected with operations
in Canadian fields.
A contract is about to be placed
by the Northwestern Company for al
aerial tram that will operate from
the top of the hill to the base where
the mill is located. This improve
ment will cost about $4,000. ant

The International Company has il

the hill. This will permit the trans
portation of ore directly through TIN
tunnel to the company's mill. which
is located at the entrance.
In driving this tunnel some depos

been encountered, and Superintend
