WARS WIRELESS IS
HEARD AT COLUMBIA
Prof. Pupin, at Alumni Day
Fetc. Tells of Orders Caught
by Listeners Here.
DIR. DERBY on WOUNDS

Regularly at I o'clock in the morning
tho British war Office sends out by wire
less instructions to the entire feet within
a radius which covers the Atlantic and
as far as the Red Sea.
The wireless plant Of Columbia tint
versity hears these orders. but cannot
understand them. of course. a. tho orders
are given in code.
This was one OF the interesting state
ments made yesterday 70 about 1900
Columbia graduates at the celebration
Of alumni! day on Morningside Heights
by Prof. Michael l. Pup!n OF the eugi-
neering department who Is also Servian
Consul in New York.
The programme kept the graduates
busy from morning until after the Penn
sylvania Columbia basketball game IN
the evening.
THE use OF wireless Geography has
transformed he method OF mnuRu-
wiring" said Prof pupn. The French
system has n central station which COW
ers radius OF 600 miles and effects
communication with all points Of the
army. Then there arc many ub-statlons
The knapsack station In carried about
in sections which weigh twenty pounds
each by four men and can bc set up IN
five minutes. The aerial wireless is car
r.cd by the a,rships and the receiving
wire is trailed from the aeroplane.
There is. Of course, no ground cOnnec-
tion, but this fact merely limits the
radius of the apparatus Elaborate au-
tomobile stations are employed and even
the cavalry carry their stations. These
cavalry stations are called wireless
whiskers' because of the peculiar appear
ance OF the outfit. There has been only
one betrayal OF the code Of any army"
Prof. Pupin then told OF the messages
sent out to war vessels by tho British
War Office and invited any OF his lis
tene-s 10 visit the Columbia plant and
hear the orders.
you may hear Aut not understand"
he continued The cod" Is made secret
by the shortening Of the wave lengths
and other changes"
Prof. l.. -. Moss OF tho mechanical en-
cheering department outlined the de-
volopment of the use OF projectilcs. \
very vivid account OF the care OF the
wounded was given by Or. Richard
Derby, who recently returned from SER
vice on the American Ambulance Corps.
DR. Talcott Williams, director Of the
Pulitzer School of Journalism. then told
how the war was reported.
The nature of the wounds as observed
might he classified into three kinds
shrapnel, rife and bayonet." Or. Derby
said. "Of 1903 cases observed, eighty
two were shrapncl wounds and every one
OF these wounds was found to he in
] Ill a.
I of these were slightly infected. There
was only one bayonet wound. The rea-
| son for the infection in the shrapnel
wounds may he attributed 10 the large
size of the wounds Of entry and the still
/ larger wounds OF issue. The pieces OF
Shrapuel carried INTO the wounds pieces
[ OF cloth. wood and straw. Tho different
7 cOlors of the uniforms could lie seen In
the pieces OF cloth extracted.
"Only five abdominal wounds were OBJ
served by me at the American hospital.
This shows that few OF those receiving
wounds in the abdomen ever leave the
] battlefield alive. There were only three
cases OF fractured skulls in the hospital.
/ ct had a Russian Count under me as
orderly. He spent his riches in brih'ng
/ patients who would not eat TO take their
/ food. This means was usually effective.
/ but some of the Turcos first wished 10
bite the coins to see II they were real.
The Count had many of the bits Of Shrap-
mel taken from the wounded mounted In
gold and returned 10 the injured soldiers.
The School of Journalism attracted "A
great deal OF attention, as the class
rooms were open TO the visitors, so that
they could see how the future Journal
lists were being trained. Another thinG
/ that proved interesting was tho eNhibl-
ton Of books by Columbia men in the
library.
In the evening the alumni met in the
commons for a beefsteak dinner. after
| which they went 10 the gymnasium to
see the basketball game.
