4 PUBLIC TEST
Washington Light is to Be
Shown This Evening.
HAS BEEN PROVEN A SUCCESS
A Beautiful IlIuminant From kero-
sene Oil-Claim of The
Midday Sun Brightness.

AT the band concert TO be given to-
night at the Hawaiian Hotel, Mr.. II. w. |
Amy. of Boston. will give an exhibit |
ton test in the grounds of the block |
OF the new and wonderful Washington |
light, light that has been a great
topic Of discussion in the city since the
preliminary test was made Of it last
Sunday night in the hotel grounds.
The Washington light made its first
appearance in America in Boston,
about nine months ago, since which
time it has been in constant operation,
largely replacing all other known il
luminants 1t has passed through all
the tests to which it has been subjected
by the fire underwriters, and its install
lation is now permissible by all insur-
ance companies under simpler cOndi-
tions than surround any other known
lighting plant.
The cost OF installation of a plant is
considerably lower than any other sys-
tenn of lighting The only apparatus
required. aside from the burners, IS
steel container or reservoir scarcely
four feet high. with diameter of about
ten inches. from which the oil is
forced by air pressure to the lamps
through copper tube One-SiXteenth OF
an inch in diameter and which is no
| larger than an ordinary telephone wire.
The air pressure is supplied by a small
force pump on the side of the tank.
| The copper tubing is quite flexible, and
no a
readily as an electric wire, and as cas-
| ilv hidden from sight. The Washing
| ton Light is an exquisite bit of mechan-
| ism the principle involved being the
| vapOriZation of a very fine stream OF
| oil and the ignition of the mixture or
| the vapOr and air in the proportion or
ten per cent of vapOr to ninety per cent
| OF air. which is said to be the most
perfect combustion known, and &C
| counts for the marvellous cheapnesS OF
| the light. It has been aptly remarked
| that by this system the lamp IS virtual
lv burning air. The marvel of this
lamp is, that each light of loo candle
mower. costs for maintenance but three
| fifths of a cent per hour, which was
the result of a test made in the Boston
Globe press rooms and also on the
Boston Commons, where the first test
lexhibition was given in the presence
of thousands of people. In comment
ing upon this light the Boston Globe
makes the following comparison as to
cost of maintenance of the Washington
Light as against their electric light in
lStallatiOn:
ELECTRIC PLANT.
CAPABLE of running twenty 1,00C
candle power arc lights:
Cost of installation about .....S 5,00C
Cost of maintenance, including
| carbons, repairs, interest on
plant, etc, per day, 20 lamps
WASHINGTON LIGHT PLANT.
Capable of running twenty lamps o
500 candle power each:
| Cost of installation about ......S $40 "
Cost of maintenance per day Tor
twenty lamps ........-...... %
As will be noticed, the electric plan
, | furnished only 10000 candle power
while the Washington light furnishe'
30 900 candle power from the sam
number of lamps. This shows IN
economy of this new illuminant, but
should be borne in mind that the cos
| of maintenance in this country WlI 0
slightly increased in proportion as Tn
cost of kerosene oil in this market eX
ceeds that of the Eastern markets.
~ Perhaps one of the greatest feature
of this light is the fact that colors al
near the same in this light as in day
light, showing it to be a pure WIN
light. from which all the acIlnlc ray
- of the electric and other ughtS al
eliminated and which are so hurtful
the ewes. This light was utilized
emnhasize its wonderful illuminatir
mower in the case of the exhibition
the Art Gallery of Doll & Richards,
RostOn. The beautiful effects produce
