Some of the greatest wrecks Of
America have been due to the inabil-
ity Of train dispatcher to get the op.
orator at a given point. Perhaps he
was absent somewhere in the station
yard on the company's business. For
a country operator is generally station
agent, freight agent and baggagemas-
ter combined. Or he may have been
asleep. At any rate he couldn't be
raised and the train dispatcher had to
stand helplessly by knowing that
train laden with passengers was rush.

That is where the telemeter would
do the trick, according to the invent
or. 1t wouldn't make any difference
should the operator be absent from his
post. If he were within hearing he
would be summoned by a gong. The
same would wake him we're he asleep.
Should he be out Of earshot and the
train dispatcher did not receive q re-
sponse to his call, signal could be
shown by the dispatcher at the point
received by the simple process Of
pressing key.
For instance, suppose a telemeter
were attached to a telegraph line be-
tween Boston and Portland Me- The
operator would be able to call any sta
ton without disturbing any other sta
tion. This system is so organized
that 1t may be quickly applied to line
without modification Of the existing
apparatus.
II train were to pass a given point
between these two stations and it
was necessary to catch that train at
the next station to prevent a collision
with another--that is where the tele-
meter would be a godsend. Perhaps
the operator at the station the train
dispatcher would try to reach could

frantic call.
If the train passed that point there
must be a wreck After the dispatcher
had tried to get the operator and re-
ceived no answer to his signals, he
would then press his keys to throw the

What telegTaphers say is the beauty
Of this contriyance is that the dis
patcher can call any station on the
system, and over single line, with.
out disturbing in the least the ordi-
nary business or working Of the tele.

struction, is attachable to the present
telegraph wires, and requires no addi.

It does not interfere with the usual

place himself into immediate commu.
nication with any operator on his line,
The telemeter seems to be human,
only more unerrlng. For after the
dispatcher has failed to raise the op'
orator by sounding the call and then
the gong, he sets the signal for the
train to stop. Immediately there
comes TO him a response automat.

acted or not
It enables the dispatcher to set and

line from his own Office. And It re-
turns information as to whether that
particular semaphore or light has been
set. No operator on the line can tam.

There Is also an attachment in con

placed in small boxes at every siding,
