LISTENING TO AN. ADDRESS

Ing with moving trains through the me-
dium of wireless waves. He answered
that in his opinion 1t could be done and
was told to go ahead and perfect his APP
paratus
He began his work for the company by
constructing a portable wireless sending
station and then having equipped an cleo
trio storage battery truck with wireless
equipment, it was found that the truck
was under perfect control OF the operator
at the sending station, he being able to
start, stop and back it with perfect ease.
After a few more months of untiring ex-
perimenting Dr. Milliner constructed cab
signal consisting of a brass box in front of
which was a glass showing a red electric
bulb and semaphore. Attached to the
outside of the box is a gong. When the
current of the sending station was thrown
on, the antennae on the roof of the cab
caught the electric wave and the gong on
the signal box changed loudly enough TO
attract the attention of the engineer; at
the same time the electric bulb blazed and
the semaphore assumed the block or danger
position, following the motion of the soma
phores of the block signal system The
antennae on the roof of the cab have since
been dispensed With the electric waves
now acting directly upon the locomotive
itself
The doctor is so far advanced with his ex-
perlments that communication between the
experiment station and Fort Omaha, four
miles distant, is held every day. the cleo
trio truck mentioned previously and which
was on exhibition at the reception, being
satisfactorily controlled by the operator at
the fort. Messages have also been received
through the aerial towers 100 feet in heigh
erected on the roof of the company's
boiler shop from Cleveland, Chicago New
Orleans, and even from a steamer in Ha-
vana harbor.
, But DR. Mliner's experiments have by
no means been confined to wireless tees-
raphy. Indeed. the greatest advance he
has made has been in the perfection of
the wireless telephone. 1t appears that its
adaptability to use with a moving train
Is much greater than had been thought.
The details of the system have not been
made known. but It is a matter of public
knowledge that the system has worked
. satisfactorily In the shop yards The mes
sage Is sent to the station along the line
: closest to the coach to which 1t is to be
sent, being transmitted by ordinary tele-
phone and is then plugged into wireless
telephone switchboard I'm order to establish
! connection with the train.
That wireless telephony will come is a
thing that is taken for granted among
electrical eXpermenters, the only ques-
ton being now how the result will be
reached. The discovery some time ago thai
common light can be made to re-
produce human speech when placed in cir
cult with a telephone transmtter under
certain conditions has formed the basis FOR
most of the experiments which have beer
made since that time and DR.. Millner'i
work in the Union Pacific research labora-
tory is being directed toward the perfection
Of the speaking arc. He Is bringing It 4
the point where It will deliver its words
as clearly and plainly as the receiver OF
telephone.
The advantage of wireless biography ant
telephony 10 the railroads OF the countr,
are manifold. When perfected they Will d,
away with the old style train ordrs vii
allow the installation OF an absolutel,
perfect danger signal system and will en-
able the passenger while travelling to keel
In continual touch with his business a
home.
The steel cars which the Union Pacifi
has been installing recently are but an
other indication OF the attitude the line /
constantly taking toward adopting IN
latest devices tending to the safety an
comfort Of It's passengers
AZ its best the wooden car cannot b
considered as a solid unit. and especial
SO when compared TO the substantial
built car with It's steel sides and othe
members securely riyted together. Tn
absence OF wooden stills, flooring etc
completely eliminates all danger from sue
