Gas cannot be compared in any way with
electricity as an illuminator and has up to
now simply held it's own owing to it's cheap
Hess ana the u1IncuILy oAr--;nnced in sub
dividing the electric current. The cost OF
the incandescent light has alone prevented
it from being brought into general use for
public buildings, theaters, churches and
similar institutions. The absence OF heat
and foul gases recommend the electric light
for all such uses, and in many institutions
like the New York Herald and Times Of
fees, the Grand Central depot, the Hoff-
man House and others that might be
named, the incandescent light has long been
in use though it did cost more than gas,
the proprietors finding it SO superior in
every respect that the matter of cost was
not permitted to enter into the considera-
ton. But the talent that has been directed
to the domain of dynamics has produced
wonderful results. The productive power
OF the dynamos has been increased from so
with the great improvement in the incan
descent lamp, the cost of electric light
ing has been reduced to a level
with the cost of gas, if not below it. A re-
cent number of the New York Financeialand
Mining Record notices the recent improve
ments in the Lumley light, as follows:
1--WE yesterday, by invitation of the general
manager, visited the Lamp Works of this
company at Brooklyn, where we saw one
of their smallest size Dynamos maintain
ing 71.16 candle power, incandescent lamps.
The Dynamo looked as if it were only able
nevertheless, we were surprised that SO
small a machine could do SO much work.
The entire system seems to be just the sort
of plant required for this country. While
it generates some Is amperes OF current
with an E.. NJ. F. of Is volts, it's price is so
nominal that any person could afford to
purchase. Now that the electric light is no
longer a matter OF doubt and the POSSIBLE
ity of a failure is very remote, the public
will doubtless take the first opportunity OF
lighting up their buildings with electric
lights. The truth really is that electric
lighting has become a grand success and

incandescent system on a large scale costs
less than gas, and by the use of the Lum-
ley system, no expert electrician is required
The company claim about one-third
more lights than most of the companies
and about double the quantity of light
gotten by one very prominent company.
They get between twelve and thirteen lights
to the horse power, while some only get
seven. Again, it should be taken into con-
sideration that their safe current, that is,
low Volts, is the only safe current for pri-
waite dwelling. The Dynamo is very COM
pact being only 2.9x1.5x1.5 and weight for
$50 lbs. The lamp is a sort of a fine hair
filiment shaped like a three-leaf clover,
which gives a soft light, the current being a
continuous one, not alternating as some OF
the Dynamos do. Altogether, we were
much pleased at the results, and we learn
they are busily engaged in the manufacture
OF lamps fnom 10 to 800 C. P. Again,
they make lamps suited for every system
and as they charge less than any other
concern, they supply many large companies
who do not make the incandescent lamp.
The process of making these lamps is most
scientific, and although the fliment resem-
bles steel, it is not made of metal, but of
some sort OF textile material, the name of
which we did not learn"
