change of ores between the Consoli-
dated Arizona Smelling company and
the Clara Consolidated Gold and Cop
per Mining company and an increas-
ed tonnage in the shipments of the
Cleopatra Copper company and the
Clara smelter are the immediate re-
suits of the recent visit of George
Mitchell, managing director of the
Clara to Jerome. Since resuming op-
erations at the Clara plant, Manager
Mitchell has demonstrated that the
Clara ores are short about one and
three-quarters per cent in sulphur for
fluXing purposes and he is deSlrous
of acquiring ores carrying high per
cent of the latter He is pleased at
the results of his negotiations and tha
interchange of ores between the Hun
boldt and Swansea plants will be
started at once and continued. He is
now making a sc per cent copper
matte at the Clara.
Speaking of the properties of the
Clara and the extensive improvements
being planned by the management to
increase the output and place the
plant on the highest lines of efficien-

"Since the company purchased the
property, seven million tons of ore
have been established and the smell

approximate expenditure of 1900, ,OOC.
A new number II blower will be
installed in the next few days which
will increase the treatment capacity
to $50 or 600 tons a day. The COM
pany is also contemplating the in
stallatiOn of a new furnace, the re-
cent invention of myself upon which

the principal European countries. The
object of the new furnace Is the
utilization of all heats generated
through or by oxidation of sulphide
ores which are wasted under present
methods. 1t will also do away with
the present expensive machinery con-
nected with smelters and convertors.
"It is also the purpose of the
management for further economical
reasons to install Stag steam gen

heat in the Stag for steam. From
present Indications this new power
will reduce by the use of carbona
ceous fuel the cost of ore treatment

coke in smelling will be entirely elm
mated by the new furnace and Stag
