EpIsoH's PROGRESS.
Preparing for another Test OF she
Electric Lishs-Ths Invsator's
Plans.
Ns9 York San. Sept. 3.


Mr.. Edison's hundred-horss power
engine is getting its finishing touches in
the Porter Allen Engine COmpany's
shops, Philadelphia, and in about three
weeks it will DO in position in Menlo
Park. The engine will make 600 revo-
buttons 0 minute. The cylinder is nine
inches 10 diameter. With this ponder.
Gus machine Mr.. Edison expects to pro-
duce the power that will enable him to
light up the 800 lamps for which the
workmen have just laid eight and one
half miles OF mains.
Forty-6ys men have begun work in
the nearly completed factory where the
lamps are made, and more will be added
in q short time. They will turn of
about 700 completed lamps q day for the
present. but Mr.. Edison expects to In.
crease the number to 1900.
Mr.. Edison's new test Of the light will
be made about October /. He says that
there is no defect in the construction Of
the lamps; that the carbon tips Of jap.
anese bamboo are perfect, and that the
new trial Of tho light Is not to be an
experiment to see II II will burn. but is
to test. on q large scale. its actual econ.
omy as compared with gas.
Mr.. Edison has not experimental
with the light for the past six months,
but his time has been occupied in pre-
pairing for what he terms the CONNER
cial introduction Of the light. Every
detail as to the wire. glass. wood. iron
and other materials, and the best and
most economical ways for f%ashioning
them, he has gone over hundreds OF
times, his idea being. he says, to have
the light q perfect success to begin with,
and to leave no improvement to be
desired. He does not want his inven-
ton looked upon in q few years a. q
crude effort in q new field. like the FIRST
sewing machine aud the pioneer reaper.
Should the Menlo Park trial. SOC to
DO made. demonstrate all that IL ex-
pected. Mr.. Edison says that the com.
pany will be selling the light to con-
sumers In New York by the first OF
Jsnusry. 1881, at about fifty cents per
1000 candles. The ordinary commercial
candle IL the standard Of measurement
for the new illuminating power. Three
thousand candles give the light Of 1000
cubic feet OF gas, so that the equivalent
OF 1000 feet Of gas in the electric light
will cost 81 so. The bamboo burners
are calculated to last in steady use for
six months. Extra ones will be fur.
nished to consumers, put up in boxes,
with sockets complete. for 9fty cents
each. The figures named by Mr.. Edison
are subject to change. but he says the
only change will be to lower prices as
the use Of the light is extended.
Mr.. Edison's electric locomotive which
has been running over the track at his
factory at forty sdd miles on hour is
dismantled at present. He 10 fitting up
an experimental freight locomotive, and
he is going to test it on steep grades.
Should Mr.. Edison's inventions have
the commercial success that he antici-
pates. Menlo Park will be threatened
with the loss OF its name aud fame. The
company associated with the Inventor
are already looking for factory building
sites in Metuchen and Railway. where
better facilities will be available.
