one Of the things she does best-at any
rate, bne of the things she likes best to +
do. How demeaning that man -made
daylight disable for,all darkness had to be
imported from France! Quite the most
interesting novelty at the Electrical Show
is the apparatus of the French scientist,
M. Claude, which toward the end of the
night session, when the usual electric
lights were turned off, suddenly flooded
the hall with white, pure, buoyant radi-
ance. People draw in their breath, as if
expecting to get also the inspiring Whit
of dawn. They go out and home along
the-as it now seems-Great Yellow
Way.
This apparatus was brought to New
York for exhibition before private sci
entific conference. But the managers of
the Electrical Show took the tubes, still
held in apparently there is tariff
barrier against them-to indicate the
farthest toward natural light that arti-
fetal light has, through electricity, ac-
complished. These tubes are five in
number, sixteen feet long. 1t requires
5000 volts. to operate them instead of
the ITO volts necessary for the ordinary
incandescent light. Fastened to the
seventh stored ceiling Of the galleried
hall. they occupy comparatively little
space. When the current is turned on it
leaps through the gases to the other end
of the tubes. The two outside glass
tubes grow an intense orange. The three
inner tubes of the gridiron grow green,
like the Peter Cooper Hewitt tubes used
in printing Offices and composing rooms
and photograph studios, the rays of
which absorb the reds and yellows of all
objects they illumine. The orange Tor
Yellow rays of the Claude tubes combin- |
ing with the green rays of the green
tubes produce the daylight.
M. Claude calls the orange-yellow tubes
the "nean" tubes, and the green ones
are mercury tubes, me" meaning by
birth, naturally, and can" meaning new
year, give clue to what struggle he had
to find name for the birth of new
day. The light shed is not so assertive
as the Hewitt-one is almost Unconscious
of it, as of something normal and artless.
Another novelty of the show is of
American invention. 1t is the new and
not yet entirely perfected nitrogen lamp
now, say, costs you $12 for current, will
reduce your expense to Sc. 1t will cut
the cost of tungsten lighting one-half,
and the Edison Company declare that
they hope to make up the difference by
the added sale of new heating, cooking,
power and other appliances. They are
willing to install it. since they foresee no
loss eventually i'll revenue from current
consumed, and indeed expect to equalize
the ''load'' which now bears heaviest at
night, economizing thus in production.
The new lamp is tungsten lamp of
high efficiency with the lamp filaments
set in nitrogen gas instead of in vacuum.
! Putting it simply, the new lamp is a
nitrogen-filed incandescent using tung-
stem filament
1T has not been so many years ago
since the consumers of electricity were
smiling over the fact that the tungsten
, lamps would give them three times as
much light for the same amount OF cur
rent as the carbon bulb consumed. The
new nitro" bids fair to cut the tung-
stem consumption almost in half de-
clares the Edison Company
1.-The first nitrogen lamps will be put
on the market in about six months
They will be large and suitable for out
door illumination. The new lamp gives
light winter than the ordinary tungsten
and comes near "daylght. The new
lamps at the electrical show are four
monster globes rated at 5000 candle
power, suspended from the four corners
Of the big central hall. These lights are
turned on for five minutes at stated in
tervals every day. This system has been
J adopted lest the blaze dazzle the eyes of
behoders, making it impossible for them
to see anything else" 1t should be
fine system for the white way.
The United States Government init
ates visitors into the processes of money
making. A fully equipped mint-a small
duplicate of the great plant at Philadel-
phla, which sight-seers must examine
from distance of forty feet-has been
constructed and brought direct to the on
locker. Coin manufacture is shown at
close range, from the time the metal en-
tiers the melting furnace in the form of
ingots till it energies from the stamping
press as finished coins. Coins (of copper
alloy) are given away lat price, to
visitors at the show.
The United States Navy exhibits the
bridge OF battleship in regular working
order. More than $4,000 has been ex-
pended in carrying out every detail of
this bridge and its electric signalling de-
vices. telephone which does not dis
connect even when the wire is broken is
also shown. Speech leaps the gap. Next
year may show how the telephone girls
oDotiuCtlVe busy may ne overcome.
Another of the Government exhibits is
complete working model of the Pedro
Miguel Lock. the construction of which
is one of the engineering triumphs of
the Panama Canal. This lock alone cost
the Government nearly thirteen million
dollars. The model exhibited is twenty
feet long and is in actual operation with
water coursing through it and miniature
ships being carried through the locks.
This model, before being brought to New
York, was kept in the White House at
Washington.
In the electric farm and dairy exhibit
cows are MIXED, butter churned and
pressed, chickens and ducks Matched be-
fore your eyes, and various pieces of
farm machinery operated by electricity
-Four white Ayrshire cows, yielding
from thirty-five to fifty pounds of milk
daily. are MIXED three times day by
electric machines. After the milk has
been run through clarifer it goes into
separator, and the cream is made into
