THE ELECTRIC LIGHT.
Edison's Lamps Break: The Inventor Yet Cen
ident of Success.

NEW YORK, Jan. 16.-The Graphic has
report from Muulo Park to the effect that
the carbon horse shoes, the main reliance
of Edison in perfecting his electric light,
have failed, aud in conse4 ucnce he has
decided TO suspend their further manu-
facture. Mr.. Edison, however, is not down
hearted.
The Post, referring to the same subject,
says: Some days ago many lamps, which
had been burning beautifully. suddenly
went ont owing to breakage Of the carbon
horse shoes. Some lamps were found to
last not more than an hour, and it was de-
cided to suspend their manufacture. Edi-
son is now at work trying to find out the
weak point which caused the trouble. He
thinks the heat emitted by the light cracks
the glass at the place where tho platinum
wires enter the lamps, and that air gets in.
No change can De found in any Of the car
bons which have been burning for some
weeks. The edges are just the same under
the microscope as before the carboas were
put into the lamps. At present there are
so lamps burning. one OF which has now
been in use for nearly Al days. new
glass blower has been engaged and moditi-
cations may be made in the lamps, allow
| ing for some means Of carrying off the teat
emitted. Edison and his assistants hope to
overcome the newly discovered difficulties
I h., l,.xhr into or cal
use 10 New York GiGy before next winter.
Edison SAYS he has hard work in convincing
people that his lamp is yet An experiment
only.
New YORK, Jan. 16 The Sun this
morning SAYS There was published yester'
day a statement that matters In the shops
of inventor Ellison in MCnlo Park, are
rather at a stand still; that many lamps
have suddenly gone out owing to the break
ing of the car bon horse shoes, and that Ed
ison is al work solving the mystery Of the
failure. It was said that the light cracks
the lamp glasses aud admits air. The arti
Gle concluded with the announcement tina
Edison hopes to overcome these difficulties
in time to introduce the light into prac;l
cal use before next winter.
MIR. Edison was shown these statement
last night.
some of those statements are false
hoods" said he, and some are quite true
The lamps have not gone out, and the car
carbon horse shoes are not broken. Tha
some of the lamps have been cracked an'
that air has thus gained an entrance to the
fame, is true. This doss not ef.Jt my in
vsntion. 1t Is purely mechanical fault
trouble with the glass. do not claim {
have perfected that part of my lamp. l ar
still experimenting.
, Edison has found that be can make an a.
, most absolutely perfect lamp by using Ger
kinds of glass and shaping them by hand
but it would be expensive, and the first oh
ject he strives to alta ain is to be cheap, an
they must be made by machinery. He doe
not want it to cost more than 20 or % Cts
Edison intends to increase the nu mber G
, lamps Id Menlo Park to 600 or 700, because
. he says, the more lamps he has to stu d
, and experiment with, the sooner be wi
:. remedy the defect that is now the only ot
stacle. So far as could DO learned yeste

5000 per share, while none is offered :
less than $500 or 80, 600.
