tirely to the laboratory Of the expert

formed continually 10 manufacture the
products OF the electric furnace, or 10
convert metals into new commercial
forms aud to refine others. The eN-
tremc possibilities OF discovery IN thls
direction are still beyond prediction
and chemists aud inventors are con-
stantly experimenting to find cheaper
ana more effective ways Of mnnufac-
turing metal products.
High temperature electro-chemistry
has consequently an important bearing
on the mining outlook aud 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 u 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
times been at nm extremely low ebb.
Speculation In copper. and attempts
to corner the market. have several
times caused panlcky prices and abnor.

many dealers had no fear Of the ult-
matp value Of the metal and carried
their stock easily through the short pc.

foundrics have been running steadily,
and the supply for the current year
will no more than equal the demand.
In the high temperature electro-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 a large extent deter
mine the actual value OF the product.
The manufacture OF cnrborundum
and calcium carbide In the electro.
chemical industries has advanced 80
rapidly that immense investments have
been made In the furnaces and plants,
while the output OF the factories Is
steadily broadening. In the steel In
dustry alone the consumption OF car
borundum amounts "a seventy-fiye
tons per month. and In nearly all lines
Il Is largely taking the place Of emery
and fcrro-sillcon. While the manuiac-
ture OF this product requires only coke,

mand upon the copper market and also

ployed ns faxes. The manufacture OF
calcium carbide Is even a larger Indus
try than that OF carborundum, and its
effect upon the mining Of metals II

that the output Will be nearly doubled.
ARTIFICIAL GRAPHITE.
The manufacture OF artificial graph
tie In the electric furnace Is another ac
complishment that has resulted In the
establishment ON large scale Of ~
entirely new industry. by passing
amorphous carbon through the electrl,

graphite, containing only one.tenth ol
one per cent. ash, Is made In large bull
In the factories. A granular graphite
suitable for many lubrlcatlng purposes
Is produced IN the electric furnace b!
capitalization OF anthracite coal. Thll
process has enabled the manufacturer
to make common form OF cheap era

There Is to-day manufactured by thl
new processes some 100000 or 1000,
600 pounds Of graphite a year, and th,
material has been employed more ox
tensively than ever before In the diner
ent trades and Industries.
The artificial graphite lends ltsel
readily to various forms OF manlnula

has made It one OF the most popuu
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 n very fin
material Is demanded.
IMITATION ALUMINIUM.
The manufacture OF artificial alumni

lance through the same process rs tina
which has reyolutlonized the graphlt
industry. Both the chemical and cleo
irlcal processes Of making aluminium
are In vogue, and the output Is 80 cor
