AS the electrical ndustr. developed, however,
and central stations of ever-ncreasing size were
built, engineers began TO look for means whereby
stations could sell their electricity to the best
advantage to themselves and the customers they
served. This resulted in the rapid development
of electric heating devices until today 100000 H.
W. or 100000 horse power is used for industrial
purposes alone. This figure represents some IN
per cent of the electric energy used for all other
Industrial uses for 1t has recently been estimated
that about 100000 horse power Is used by cleo
trio motors in manufacturing
The principal factor contributing to the increas
cd of electric heating appliances is the way
in which they answer the modern demand for con-
servaton-conservation not only in the saving of
natural resources but the saving of time, mate
rails and the reduction of the uncertain personal
element to minimum, well the improve
ment of the product Despite the fact that the
conversion of fuel into electric heat is only reach
ed after long and complicated series of steps,
whose ultimate efficiency is but 20 per cent it has

Roadway that 1t bids fair to surpass, in energy
consumption, both the light and power branches
of electrical service together
With the enormous amount of undeveloped n.y.
drauc power in the country, it is not easy to
predict where the final stopping point will be, be-
cause it is by water power that electrical energy
can be most efficiently developed regards money

electricity produced automatically, can be grasped
only when it is realized that there is one hundred

the same line of conservation manufacturers are
beginning to realize that the elimination of spoiled
and unfit products, whether rendered by inefii-
cient and unreliable methods of heating or by
careless employees is just much conservation
as anything else. Also the elimination of unneces-
sary labor, and the establishment of cleaner safer
working conditions, tend toward the attainment
of the rapid rate of production which is the
paramount demand of the present Industrial era.
Thus the variety ct processes to which electric
heat is applicable has given rise to many devices

TO take the brass furnace as typical exam
pie of what can be done by the application of
electric heat in overcoming the difficulties of spe-
cialized operation in the fuel-heated BRASS fur
mace. one of the greatest drawbacks is the loss
of zinc through volatilization and oxidation due
the high temperature OF the applied heat, well
as the atmospheric conditions surrounding the
bath.
In the eectrically-heated brass furnace both
these conditions are absolutely under the
troll Of the operator. There are several types of
brass furnaces in use today: the arc type. which
has no automatic control but low first cost the
induction which just fits field where produc-
lions can be placed on q 24-hour basis; the car

This furnace se operated at higher tenn
perature than tie carbon resister type, and at
the same time can be regulated to operate at low
or temperatures economically, but with the addi-
tional feature of automatic control.
