vised. so to intensity these waves that
they will overcome the pull of gravity.
He claims 10 be able to make various
objects Of considerable weight float
around in the air as fish floats in the
water.
10 the scientist who has studied all
the possibilities of wireless it seems
possible that the time yet will come
when not only may man control float
ing airships from some central station,
but when the power that actuates those
craft may itself be communicated to
them from such stations
Almost as much progress has been
made in the field of practical untliza-
ton OF wireless as IN the eXperlmen tai
laboratory. The big chain of wireless
stations already contracted for by the
British government viii place practlc-
ally every inch Of the earth's surface
in the field of possible communication
with London. The principal stations
viii be at London, Cairo, Alden, Pre-
toria Bangalors and Singapore. These
stations viii be within reach Of other
stations throughout the world.
Seven Stations in This Country.
The big system of the United States,
with the initial station at Arlington al
ready in operation, will consist of seven
stations. One OF these will be at Pan
anna aQOluEE at San FRANCISCO ana
others at Pearl harbOr, Hawaii ana on
the islands Of Guam, Luzon and Samoa.
With these stations in commission it
would be difficult for the big American
battleshlp TO get out Of touch with
Washington anywhere 1t might be sent.
The big towers of the Arlington sta
tion, one of them 45 feet higher than
the Washington monument, are con
spicuous additions TO the landscape of
the capital city. The United States
h1 ST nd
vessel in the navy has wireless equip
ment
The French also are laying out plan
for a great world wireless system. Al
ready France has the greatest wireless
station in the World-the one on Eiffel
tower. This station has a range of
some 1000 miles, and it is able to start
its messages hurting through space
with the power of millions of volts be-
hind them 1t uses so much power that
at night the wires become illuminant,
and the top Of the big tower has to be
insulated with 20 feet Of insulating ma
terial
This EiffeI tower station has demon
strated what a great aid wireless tele-
graphy may be to the geographers of
the world. For the purpose of ascer-
tanning the longitude Of Tunis, a clock
in the big station near there was con-
nected with the big clock in the Eiffel
tower. It was found that it required
the signal the 1-7000th part of a sec
ond to travel between the two points,
and as IL has been definitely proved that
electricity travels 1S6, 900 miles q second,
the calculation Of the longitude became
easy. When the royal astronomer of
England fixed the longitude of Nalen-
tia, little island off the coast Of
Kerry, where the Atlantic cables go
down into the sea, he had 80 chrOnome-
tiers carried back and forth between
Nalentia and Greenwich p times before |
he considered the longitude properly !

One of the objects Of inventors now
adays is to bring out a compact wire

Of course the smaller the outfit the |
wider its field Of usefulness. An army |
officer has designed a field sending and |
receiving outfit which has a total |
weight of less than so pounds. The re- |
eelVlng equipment occupies a box 10 4
inches deep and Is square, weighing I
about 26 pounds. The generator weighs =

May Talk From Trains.
It is probable that within a short |
time people win be talking from NOV /
ng trains by means Of the semi wireless !
outfit known as the 'railiphOne" This /
instrument is being tried out and has
met with success. Just now the Penn
Sylvania railroad is considering the l
equipment of some of its trains with 1
wireless and of trying to use it instead /
Of the telephone and the ordinary tele- /
graph in train handling. 1t is said that |
the wireless apparatus does its best
work in bad, stormy weather, when the
apt to be out Of commission.
Some of the big department stores /
are now being equipped with wireless /
outfits which permit them to send and
receive business messages direct. One
Of the big daily newspapers in New
York has almost entirely given up the I
transatlantic cable in getting its
European news and is now getting
some 10000 words a week across the
by wireless.
The navy department has dropped the
word, wireless" from its vocabulary,
using the word, 'radiogram," instead
or not it is proper to say that
4 photographer sent a radiOgram by
photograph, the navy department has
not decided, but hereafter any wireless
message sent or received by the navy
department must be 'radiogram."
