A most interesting, as well as won
derful, experiment in telegraphy was
successfully tried recently by the Balti-
more u Ohio Telegraph company oflic-
ials. They succeeded in telegraphing IN
a railroad train while going at the rate
of forty miles an hour by the Phelps in
duction system. The experiment was
conducted by Mr.. lholps, the inventor,
and under direction Of the Baltimore &
Ohio ofic ais. Passenger Agent Pang-
born and Manager McLaren went on the
car. and Mr.. Weaver, the electrician.
remained at the receiving Office in New
York. The experiment was tried on the
Harlem river branch of the New York
& New Haven railroad.
Soon after the train was started, and
while going at the rate Of forty miles an
hour, the operator in the car called
New York. A direct wire had been fur
nished through to Baltimore and into
President CARROTS private Office in the
Central building in this city. The gen
tlemen in the car awaited the answer
with anxiety. Soon the instrument be-
gan ticking as loudly Ms if in a station
airy Office. New York had responded.
The induction system worked. Mai.
Pangborn then indited a telegram to
President Garrett, saying that the
Phelps induction system was n success.
The telegram went direct to Mr.. Garrett,
and an answer was received by the ex-
perimenters on the car; Your teie-
gram has been delivered TO President
Garrett in his private Office" Mai.
Pangborn then wrote another: "Presi-
dent Garrett, | am t~elegraphing to you,
on a train going forty miles an hour, by
the Phelps induction system. The wire
in our car is seven and one-half inches
from the wire laid on the ties of tho
track
While the operator was sending
the dispatch, Maj. Pangborn no.
ticed that the train had gone its
twelve miles, and that it would soon
pass over the wire in the wooden trench.
lie said nothing, but let the operator
continue. The train left the box be-
hind. As it passed over the end there
was a fainter sound of the ticking of tho
instrument, but the message continued.
The induction was so strong that the
current had gone to the wire on the
telegraph pole forty feet from the train.
1t seemed marvellous to the experiment
ers. Sitting in a car with no wire
nearer than forty feet, and to send and
receive messagesl When the train re-
turned the experiments were continued,
and it was found that the inductor
worked as well rs or the other
track. The message was sent over
the wire in the wooden trench on
the other track, eleven feet away.
OF course there wa a difference in the
sound from the one received and sent
when the car was over the wire and
when eleven feet from it. On the re-
turn the telephone was connected with
the induction system, and a message on
a wire 90 feet away vas heard. The
sender was in New York, and he was
sending a message to his wife in New
Rochelle: 81 will not be home tonight.
Business detains me in the city"
Mr.. Phelps stated that a system OF
bells could be placed on the engines and
worked by the induction system. 50 that
trains could telegraph to each other, and
a system arranged so that when trains
were within 1000 feet of each other a
bell would ring. announcing the mum
Der of the train ahead.
