structible carbon and to generate electrici-
ty economically. While scores Of inventors
have worked on this problem, the world
has looked more confidently to Edison than
to any other. For eighteen months he has
worked indefatigably, even to melting
search in the mines of the world for scarce
metals deemed essential to bis success,
while dozens OF skilled workmen and spe-
cialists have contributed their labors to as
sist him. Many times have correspondents
announced his achievement; as often has
disappointment come. At last, in the
closing days Of 1879, Edison himself cried

the world that he has mastered the mys-

oratory, are lighted with the new illumina-

and deny, the general belief seems to be
that Edison's triumph Is complete, and no
better evidence Of this Is needed than the
depreciation Of gas stocks and the advance

Is only one point upon which there can be
doubt-the permanence of the carbon illu-
minator. For the carbon, after innumera-
BILE experiments, he has adopted common
white paper, such as this We print on. The
discovery of it's adaptability was almost ao-
cidental, and it is pronounced the best SUBJ
stance possible to obtain. Several thick
nesses of it are laid togsther and little
horseshoe-shaped piece punched out. This
piece is then subjected TO intense heat in a
furnace, leaving only the carbon of the pa
per. The little arc of carbon is then stood
on its points inside a glass globe, the wires
being connected to the points and the air
exhausted from tue globe. When cleo
tricity is applied the horseshoe-shaped
carbon becomes incandescent, giving out a
pure, steady, white light Those now in
use give about the same light as an ordi-
nary gas jet, but the illumination is capa-
Bile OF being many times increased. The
carbonized paper costs abont one cent the
lamps about twenty five cents each. We
have as vet seen no estimate Of the cost of
generating the electricity, but it is claimed
TO be but fraction of the cost of gas light
where it IL cheapest and best. A few weeks
OF practical use will demonstrate the de-
structibility or indestructibility of the
carbon. Edison says he has experiment
ed upon that until he is satisfied, and
claims that the air being totally exhausted
from the globe combustion is I'm possible.
Others dissent from this and claim the car
bon will gradually impair; but 1t mast be
remembered that successful electric light |
will as certainly supersede gas-in which
enormous capital is invested-as oil has |
superseded the tallow candle. 1t will also |
effect the oil market, and OF course the |
electric light will be fought as vigorously,
although we trust not as viciously, as was
Gallileo's theory. Even If there are yet
defects they are remediable. We accept
the electric light as success.
