Of So 500 by Mr.. Allen of Philadelphia, under
the direction of Dr. Coleman Sellers. The
model shows the falls with real water rum
ming over them, the intake canal, the power
house on its bank, which will be lighted at
night by tiny incandescent lamps, and the
wheel pit down which the water falls, turn
ing a turbine at the bottom, and then dis
charging through a long tunnel into the
river under Suspension bridge.
The machinery by which the power is con-
Quoted from the wheel back from to the
surface and thence distributed is also shown.
The shaft and tunnel are made OF glass go
that the operation can be clearly seen, ana
only distilled water can be used, as ordinary
water would clog the delicate turbine model.
There will also be near this exhibit model,
sixteen feet wide, of the Erie canal, with
canal boats and a power house on the banks.
This will show exactly how the energy gen
Grated at the Falls is applied by means Of
trolleys to the electric mule" which pulls
the boats.
The above described model is exhibited
by the Historical and Loan Exhibit commit
tee, and to Mr.. T. C. Martin, chairman Of
that committee belongs the credit of origin
ating the exhibit. Mr.. Martin is most anx-
ious that the model be run with motive
power generated at the Falls. The Western.
Union people have offered MN the use oi
two of their wires for the purpose OF trans
mission, providing the amount of electricity
to be sent be not 90 great as TO endanger
the instruments and buildings throush
which the wires pass. 1t would be CON
viewed by an iron wire to Buffalo, dis
tance of twenty miles, and the rest of the
way over the usual copper wire.
Mr. Martin also proposes to nave the
electricity brought from Niagara transferred
to the submarine cables so that communica-
ton with London may be maintained py
means of power generated at Niagara Falls
The success of the scheme depends upon
the amount of power needed to run the
model which should not exceed one-quarter
horse power. Mr.. Nicola Tesla pronounces
the scheme perfectly feasible, and says that
starting with one horse power at the falls
end. they would certainly have power enough
to do all they would wish. The Long DIS
tance Telephone company has arranged 10
have instruments in the immediate vicinity
of this exhibit which will produce the voice
of the great waters, 80 that at the same
time one can see and near Niagara Ha"s
500 miles away
To the great disappointment of electricians
as well as the world in general, Mr.. Tesla
has announced that he will make no eXhi-
biton of his work. The most valuable of
his instruments and models were destroyed
by fire year ago and Mr. Tesla has
nothing on hand that would adequately repre-
sent him.
NEW SYSTEM OF LIGHTING.
One of the most important exhibits will
be that of a new and valuable discovery
known as the Moore "Etheric" Lighting
tubes THIS Is the result OF tne laDOTS OF
Mr. ID. McFarlan Moore of Newark In the
apparatus, which is very simple, an electric
current passes through vibrator contained
in a small glass tube, exhausted to the
highest possible degree, The atmospheric
resistance being removed the vibrator is
enabled to attain a rate OF 100 vibrations
a second. From this vibrator the current,
pulsating at the same rate, passes through
the lighting tubes, which may be of any
size or shape and In which only low
vacuum Is necessary. These lighting tubes
contain no filaments. their ends being simply
coated with metallic paint with which the
wires are connected.
The rarefed air In the tubes being eX
cited by the pulsations Of the current conf
ing from the vibrator becomes luminous and
shines with a phosphorescent glow. The
light is very pleasant to the eye, and is so
evenly diffused that II will offer great ad-
vantages for ordinary lighting purposes, as
well as for such special uses as photography,
illuminated signs. etc. One great point of
superiority of Mr.. Moore's system lies in
the cheapness OF its manufacture, the cost
Of production and maintenance being less
oned by the absence OF f1lLments. Mr..
Moore will show these new lamps in a dark
room about ten feet square.
ELECTRICITY IN THE HOUSEHOLD.
The possibilities OF electricity in the
household will be displayed in another sec
tion in the shape OF electric stoves in prac-
teal operation, which Will bake biscuits In
three minutes; bread in teni chahng dishes |
