THE GROWTH OF THE
TELapHONE.
The Wireless, the Automatic and Other Kinds

the prevention of fires and the repreS-
sion of crime. In all cities they trans
nit messages free to fire alarm and
police stations. In Chicago the call for
police is Main Is. and 1T was used 62.OO5
times in 1909. The fire alarm call Main
was used S,S25 times. American teIe-
phone companies could well initiate a
COpenhag gen company which installed
monographs in it's central office When
ever an irate subscriber abused an oper-
ator over the wire, she simply switched
his voice into the phOnograph. If he
were at fault, he was summoned to
the office and asked TO listen to him
self talk. AS an -repressor it has
proved a great success.
A Telephone Clock.
Selling time service as a by-product
OF the business is one of the latest
wrinkles in telephones. For many years
the Western Union has sold standard
time service. though it never has pushed
the idea. Now comes a Missouri man
with a master clock in the telephone
office with which clocks in the homes
and offices OF subscribers are con-
nected. Where the experiment has been
tried II has proved satisfactory. and 1t
is not improbable that hustling tele-
phone companies everywhere will adopt
the idea.
Telephones are now sometimes at

because of it, In this way the busy
man can keep in touch with his office
while being shaved or having a hair
cut.
The German PateBt.
The Germans have a telephone which
seems to be the acme of convenience
The transmitter and receiver are made
In ri f,,e 4F,14 he,
the subscriber holds the receiver to his
ear. the transnitter is in the correct
position before his mouth. Thus one
hand is always left free and both trans
raitter and receiver can be moved as rar
as the cord will permit
4 Philadelphia inventor has brought
out fire-hOse telephone. II consists
of a wire connection woven through the
lengths OF the hcSe and a small portable
telephone attached to each end OF the
line of hose In this way the firemen
may talk with the chief and get orders
even when the latter IS block or more
away from the fire Whenever the hose
sections are put together the wire con-
nection is made automatically.
Photos by Telephone.
Thomas Tl,orne Baker in charge of
the photo-telegraphic department. Of
the London Daily Mail. has perfected
new Photographic transmitting device
which he calls the teIectrograph. 1t IS
being used between the London and
Manchester offices of the Mail especially
for the transmission of pictures from
the London. office to the Manchester
office, where they appear simultan-
eously with their publication in Lon
don From four to five hours are
saved over the transmission by mail.
1t takes one hour 10 transmit a picture.
The illustration is first photographed
through a screen ruled like a checker
board with seventy-five lines each way

developed plate IS made to contain little
fish-glue dots, one dot for each mesh
in the screen As the needles, CORES
ponding to the needle of a photograph,
passes over the plate these glue dots
alternately make and break the circuit.
and corresponding impulses are sent out
over the wire At the other end OF
the line a needle acts in the same man
ner on paper so sensitized that the
little impulses of electricity make a
black mark at each mesh. correspond
ing in intensity with the degree of the
impulses. Consequently. when the re-
producing needle has followed the
sending needle through all of the little
meshes on the sending plate. an exact
reproduction of the original with all its
graduatiOns of light and shade is the
result A line between London and
Paris is beng planned and will soon be
in operation.
Farming by Wireless.
The very newest thing in electrical
circles is Farming by Wireless" Al
the recent Hobby Night of the National
Press club in Washington. professor
Willis Moore stated that the highly
electrified northwest wind is the source
of Americas remarkable energy, and.
in keeping with this idea. some Eng
lish scientists are making experimental
efforts to transfer the energy of the
atmosphere to products OF the soil
They rigged UP an oil engine and dy-
ramO and covered some u acres of
land with a series of parallel wire lines
not so high as telegraph lines. but still
high enough to be out of the way OF
farm operations Through these wires |
electrical currents are sent over the :
growing crops with remarkable results /
Anyone walking below the wires can /
feel the effect on the hair of the head /
as of a cobweb on the face. At dusk. /
just before the power is cut off. there /
is n glow visible wherever a leakage of
current occurs. The current is turned
on several hours each day. and the
photographs of crops grown under such |
stimulation show that by this means I
production may be increased by one
half.
