form Of a revolving drum, the inner
lining is comprised of a.series Of car

ormetal to be smeletediss placed in:

opening is closed air. tight and the

volution is. supplied by additional
current. =
The carbons which line tile inside
of the smelter are made in va rious
sizes, according to the capacity of
the machine. Instead of having a
series of carbons on each surface
Mr.. Hatch says he could have just
one large carbon, his patent max
| ing provision for this, but the series
of carbons require less Of that ma
terial and give more surface, as be.
tween the carbons there are two
surfaces where there would be only
one if the intervening space was
filled. After copper is smelted it
runs into series of socalled set
thing tanks in which the metal is
refined t:>
Mr.. Hatch said that THE material

does not have to be stamped or
concentrated. The inventor claims.
that the rock of the Nonesuch mine, ):
in the Porcupine mountains in
Ontonagon county, can be smelted
in his smelter without first being
being washed in a stamp mill. The
None such rock carries native
copper freely, but in so. fine par
ticles that it cannot be saved in the
washing Local#men who
have looked into the matter say,
none such could he rnadea success
| with the installation OF an electric
smelter- plant at the property.
Besides the advantages in saving
fuel costs, time and labor, Mr..
Hatch claims his smeIter requires
only one heat for the simultaneous
smelling of gold, silver, copper,
zinc, lead, etc. II makes complete
and perfect separation with the one
heat whereas with the ordinary
methods in use there must be as
many heats as there are different
ores smeIted. The smelter in one
process separates the sulphur, and
delivers the lead and zinc distinct
and the copper, silver and gold in
mat which is then refined. l.
Mr.. Hatch is an expert electrical
engineer by profession. He has
spent many years and considerable
money perfecting his invention
and believes he iss now = ready
to reap the benefit. Mr.. Case, who
was formerly superintendent of the
Dollar Bay smelter, is interested in
company: which plans the :erec.
ton of an electric ssmelter plant at
the 500, the capacity of which will be
L000 tons per day. The Hatch Elec-
trio Smelter company, which will
only manufacture the machines,
having no intention of going into
the smelter business, will furnish
Mr.. Case and his associates with
either 200. ton machine or a mum:
Der of machines of smaller Ca
pacity. A 100 ton machine is now
in recourse of construction and will
be completed in a few months. As
soon as the, company is in posi-
