AN AUTOMATIC ELEVATOR.

AN AUTOMATIC ELEVATOR.
The Edison company will also show
an elevator automatically operated by
electricity. The person desiring to as
cend, enters the car, closes the door
and presses the button marked UP;
another button stops it, and still an
other sends it down. Safety is ensured
as the circuit is not complete unless
all the doors opening on the shaft are
closed. nor will any door open unless
the car be exactly opposite it.
This company will also show an i'm
proved stop-cylinder printing press, in
which the motor is connected directly
to the shaft. This is a simple illustra-
ton of what is now being very gem
orally done in the way OF dividing cleo
trio power by applying directly to
every machine a motor of sufficient
size to drive it, which can be put out
of use when the machine is not in
operation.
The General Electric company will
combine with the Edison company in a
very complete exhibit of the evolution
Of the incandescent lamp.
AN ELECTRIC BUOY.
Models of the Gedney Channel Buoys
will make very interesting exhibit,
as they mark an era in harbor lighting.
There are ten or twelve of these buoys
on each side of The Gedney channel at
the entrance to the New York harbor.
They are like gigantic wooden lamp
posts, seventy feet long, anchored by
heavy "muchroom'' weights, the top
of the spars projecting about five feet
out of water at high tide. The lamp is
made of very heavy bell glass and is
five inches in diameter. 1t gives a
light of 100 candle power, and the fila
ment is spiral From the dynamo sta
ton on Sandy Hook beach run two
carefully insulated, submarine cables
lying along the ocean bed. Offshoots
from these cables supply each lamp.
The entire length of cable used. in
Guiding offshoots, is little over six
miles.
ELECTRICITY FOR GROWING
PLANTS.
1t is expected that the horticultural
department of Cornell University will
make an exhibit of the application OF
electricity to growing plants. They
nave lately been making some success
fuI experiments by radiation from arc
and incande5cent lights directly upon
the plants, and forced Easter lilies two
weeks ahead of time. In Russia two
years ago very satisfactory results were
attained by passing an electric current
through the ground in which the seeds
had been planted.
A COMPLETE ELECTRICAL LABO-
RATORY.
A complete electrical laboratory, fit
ted up with the finest and most COM
plete Instruments and apparatus, will
be in charge of Max Osterberg, of
IL Il;
conduct a number of interesting ex-
perimeuts. This laboratory is de-
signed to show the actual methods of
studying the electrical science, and the
processes gone through to obtain well
known results. For instance, on large
screen will be thrown the magnified re-
Election of an arc light in which the
carbon points can be seen to diminish
as the light burns. There will also be
standard instruments which will show
the method of measuring the electric
al units of pressure quantity and re-
sistance, i. e.; the volt, the ampere and
the ohm.
The United States patent office will
els in charge of an expert.
There will be an extremely fine col
lection elf cathodographs, taken by the
Roentgen rays, which will be mounted
as transparencieS, such as q man S
hand with 70 shot in it, Shadows foot
filled with splinters of glass, Jack Nc
Abilities famous left arm and shoulder
Mr.. Tesla has promised some very fine
specimens.
Mr. E. Lynde Morse, son of Profess
sor S. F. B. Morse, will allow to be ex-
hibited for the first time all the appa-
ratus his father left, and models will
he made that the great inventor de-
signed but which has been destroyed
or mutilated, so that the work will be
completely illustrated. The medals
bestowed upon Prof Morse will also
be shown.
ELECTRICITY FOR RAILROADS
Electricity as applied to railroad ser
vice will be illustrated from the begin
ming. the earliest models of electrical
locomotive having been built by Thorn
as Davenport in 1888. Another model
was built by DR.. G. Q. Cotton in 1S4S-
40, in which the track was used as
part Of the circuit as in the modern
trolley system. In 1852 Charles Graf
ton Page built working model of a
locomotive which he exhibited to
committee of congress to convince them
that electric force could be applied to
railroad service. He made a trial trip
from Baltimore to Bladenberg, a DIS
lance of fifteen miles, when one of the
parts became heated, cracking one of
the Jars and causing the liquid to leak
away This model will be exhibited.
RARE BOOKS ON ELECTRICITY.
A remarkable and novel exhibit will
