tries that were previously confined en-

formed continually TO manufacture the
products Of the electric furnace, or to
convert metals into new commercial
forms aud to refine others. The eX'
IRENE possibilities or discovery In this
direction are siill beyond prediction.
and chemists and inventors are CON
stantly experimenting to find cheaper
ana more effective ways Of mnnufnc'
turing metal products.
High temperature electro-chemlstry
has consequently an important bearing
on the mining outlook and the metal
trades In general. The consumption of
many OF the minor metals by the new
group of Industries has become sud
denly so great that the demand exceeds
the supply In the use OF copper IN
particular, the consumption has tended
toward rapid Increase. while the
price OF metal has steadily advanced.
The comparative production Of copper
for the past ten years has averaged
about nine per cent. increase. while the
consumptlve demand has advanced In
/. recent years until the total stocks OF
copper IN the country have several
tunes been at nm extremely low chb.
Speculation In copper, aud attempts
to corner the market. have several
times caused panlcky prices and abnor'
NAL conditions, but the trade demands
have been steady and healthy. aud
many dealers had no fear Of the utl'
mutp value Of the metal and carried
their stock easily through the short pc.
RODS OF depression Mills and brass
foundries have been running steadily.
md the supply for the current year
will no more than equal the demand.
In the high temperature clectro-chemi'
cal factories copper will he more OF n
factor than ever before. and the con-
sumption OF the metal for electrical
purposes must to large extent deter.
mine the actual value OF the product.
The manufacture OF carborundum
and calcium carbide In the electro.
chemical industries has advanced 30
rapidly that immense investments have
been made In the furnaces aud plants,
while the output OF the factories Is
steadily broadening. In the steel In
dustry alone the consumption OF car.
borundum amounts "a seventy.hvc
tons per month. and In nearly all lines
n Is largely taking the place Of emery
and ferro.sillcon While the manuiac-
ture OF this product requires only coke,

ARTIFICIAL GRAPHITE,
The manufacture or artificial graph
tie In the electric furnace is another ne
complishmCnt that has resulted In the
establishment ON a large scale OF M
entirely new industry by passing
amorphous carbon through the electrl,
arc artificial graphite has been mad,
for many years past but It's CONNER
clal manufacture In the electric furnac,
is scarcely year old. Almost pur,
graphite containing only one.tenth Of
one per cent. ash, Is made In large bull
In the factories. A granular graphlt,
suitable for many lubrlcatng purposes
Is produced I'm the electric furnace by
capitalization OF anthracite coal. Thli
process has enabled the manufacturer
TO make common form OF cheap era
phlte. which enables many uses for 4
heretofore denied by virtue Of It's cost
There Is to-day manufactured by thi
new processes some 100000 or 1000,
600 pounds Of graphite a year, and thu
material has been employed more ox
tenslvely than ever before In the diner
ent trades ana industries.
The artificial graphite lends ltscl
readily TO various forms OF manlpula
tlon. which opens up for It new field
for usefulness. Thus II can be planel
ana cut by machinery ana used 10
screwlng up against beams and grder
where needed without splitting o
breaking The ease with which Il ear
be machlned by ordinary wood tool
has made It one Of the most populu
materials yet manufactured by IN
new electric furnaces. The elimination
OF Impurities from the graphite by tn
electric process also recommends th
product for the more difficult and ex
acting trade demands where very fin
material Is demanded.

tance through the same process as tina
