graphophone or photograph. By the use
OF this device a telephone or telegraph
conversation can be recorded on a steel
wire OF tape and reproduced at any time
and as often as desired without the record
deteriorating.
In this apparatus a steel wire, or a steel
band, is moved by any suitable means with
considerable velocity between the poles OF
a small electromagnetic On speaking into
a telephone transmitter Joined on the cir
cult, the undulatory currents set up in the
t%ransmitter react upon the electro-magnet
and cause a continuous variation in the
direction and in the degree of magnetism
at the poles Of the electro-magnet.
These variations are permanently
recorded on the steel wire as II rushes by,
and when the message is complete the
steel wire retains a definite record Of what
has taken place In the shape Of a %continu-
Gus series Of transverse magnitized lines
varying throughout in their polarity and in
their strength. On connecting a telephone
receiver to the e~lectro-magnet, and again
starting the wire on its course. says the
Telegraph Age, this magnetized wire gen.

most absolutely perfect manner.
Aerial Telegraph Receiver.
Widespread interest has been aroused,
says the Scientific American, by the ex-
periments which have been carried on by
Prof. Fessenden with a new form Of aerial
Geographic receiver, which is claimed to
give promise of considerably greater ra-
ptdity than tho ooboror yyith vyhl,k tbn n,h-
lie is generally familiar. The experiments
have been carried out under the auspices
of the weather bureau and have extended
over a period Of about two years. Some of
the results achieved have been made pub
lie by the bureau and they are considered
to foreshadow a great Improvement in the
speed Of aerial telegraphy. The work has
been carried on between Hatteras inlet and
Roanoke island, over a distance of fifty
miles, and messages have been sent and
received without the use Of the eoherer, the
place Of which is taken by the new re-
ceiver, which Prof. Fessenden calls a wave
detector. He claims that he has worked
1t expeTimentally at speeds which would
be equal to over 500 words a minute, and
this with only about 25 per cent increase
Of energy per signal over that which is
used with the ordinary apparatus. We un-

making and breaking of the circuit is so
delicately adjusted that the higher speeds
are easily realized.
Barbed Wire Telephones.
They are inaugurating a telephone ex-
change In Fort Benton, Mcnt., that will put
the embryo telephone companies entirely in
the shade.
Fort Benton's latest effort is a barbed-
wire telephone communication Being by
instinct and association COW people, they
resented the genesis Of the barbed wire,
and when it was discovered that 1t was
one Of the evils that came with the rail-
road and threw the cowpuncher, the bull
train and the river steamer out Of the
game, they decided to take a material view
Of the situation, and the result is that they
are preparing to have a telephone exchange
which will take in evory ranch from the
Missouri river north to che Canadian line
and south to the H~ighwood mountains.
Among the duties of the operator at the
toll station, which will be situated at Ben
ton, will be calling the ranchers on the
various creeks in the morning. notifying
them when the trains are twelve or four
teen hours late, and giving the sheepmen
the latest report OF the weather bureau, so
that they may be ready during lambing
time for The storms which are so destruc-
tive in that section.
Ranches are strung all along the line
from Benton up shonkin creek to the noun
tains, and with a short addition to the
fences which run continuously, the line
will be carried across the Highwood noun
| Nn9ng old TaoE C0nnnllvfa ranch AT
Eagles Head to the thickly populated High
wood district and to the Judith Basin.
When the line is finished the ranchmen
Of northern Montana will only have to
step to the phone to be in connection
with every city in the state. On emer-
gency cases he can call a physician, or q
minister, as the case requires. The latter
is Of particular importance in the Bear
Paw and Little Rocky region, as some
men down there have still the old-time
habit Of dying in their boots, and even
telephone connection with a sky-pilot Is a
desirable modern convenience.
When a bunch of beef steers stampedes
and goes through the barbed wire. central
will know that the line is in need OF repair
and that the beef Steers Of the Square
outnt are losing flesh by the pound.
Fast Motor Trains.
Swifter than the fastest locomotives, cleo
trio cars will begin next month to speed
between Chicago and Elgin, Batavia and
Aurora, reports the Chicago Inter Ocean.
Few trains have ever been run at the speed
which, IL is claimed, these electric cars will
make. They will run so fast that riding in
them will be like facing a hurricane and
the breezes which will sweep through their
open windows forbode disaster for curls,
frizzes OF any small articles that are not
held tightly by their owners. 1t is a ques-
| tion whether a passenger with his face un-
protected will be able to sit at an open win
dow Of one of these cars as in the ordinary
electric car.
On the trains the newsboys, along with
their line Of fruit and antiquated literature
will carry a stock of face masks and their
first trip through the train will be to urge
the women passengers to rent a face mash
and save your hair from being blown down. "
Like giant racing automobiles the trains
will speed across the country, their occu-
pants peering through goggled face pro-
tectors and sheltering their heads beneath
