COLUMBIA HEARS
 WIRELESS ORDERS
But Cannot Understand British h.
 stIuClions, Says Prof. Pupln.

AN'" 'Vihs eD. 1Os--1NSk Hi o'clock in the morning the British war office sends out by wireless in- structions to the entire fleet within a radius which covers the Atlantic and as far the Red Sea.
 The wireless plant of Colum bia Uni Versity hears these orders, but cannot understand them. of course, as the orders are given in code
 This was one of the interesting statements made yesterday to about 1,500 Columbia graduates at the cele- bration of alumni day on MorninH side Heights by Professor Michael I. Pupin of the engineering department. who is also Servian consul in New York
 The program kept the graduates busy from morning until after the Pennsylvania-Columb basketball game in the evening
 Change Brought by Wireless
 'The use of wireless telegra phy has, transformed the method of maneuver- ing, said Professor Pupin. The \ French system has a central station8 which covers a radius of 200 niless and effects communication with all points of the army. Then there are many sub-stations The knapsack station is carried about in sections which weigh twenty pounds each by q four men and be set up in five minutes. The aerial wireless is car rfed by the airships and the receiving wire is trailed from the aeroplane. There is, of course, no ground connec- ton, but this fact merely limits the radius of the apparatus. Elaborate automobile stations are employed and even the cavalry carry their stations. These cavalry stations are called wireless whiskers' because of the ps- culiar appearance of the outfit. There . has been only one betrayal of the code e of any army"
 Professor Pupin then told of the messages sent out to war vessels by the British war olive and invited any of his listeners to visit the Columbia plant and heaer theorders f&
 You may hear but not under stand, he continued. The code IS made secret by the shortening of the wave lengths and other chanses9
 Prof. l.. D. Moss of the mechanical engineering department outlined. the development of the use of projectiles. ~l A very vivid account Of the care of the wounded was given by Dr. Rich ard Derby, who recently returned from service on the American Ann bulance Corps. pr. Talcott Williams. director of the Pulitzer School of Journalism, then told how the war ' was reported
 Most Wounds bs Shrapnel
 The nature Of the wounds as ob- served might be classified into three kinds-shrapnel, rife and bayonet," Dr. Derby said "Of 103 cases ob. - served, cighty-two were shrapnel wounds and every one of these wounds was found to be infected. Twenty were rife wounds: four of these were slightly infected. There was only one bayonet wound. The reason for the infection in the shrap- nel wounds may be attributed to th&v large size of the wounds of entry and tho still large wounds of issue The pieces of shrapnel carried into tae wounds pieces of cloth. wood and straw. The different colors Of the uniforms could be seen in the pieces of cloth extracted.
 "OnIy five abdominal wounds were 1 observed by me at the Am merican hos pital. This shows that few of thoscs receiving wounds in the abdomen ever leave the battlefield alive. There were only three cases of fractured skulls in the hospital. ta
 "I had a Russian count under me orderly. He spent his riches in bribng patients who would not eat to take their food. This means was X usually effective. but some of th~ Turcos first wished to bite the coins to see if they were real. The count had many of the bits of shrapnel taken from the wounded mounted in gold and returned to the injured sol diers."
 The school Of Journalism attracted a great deal of attention, as the class rooms were open to the visitors, so that they could how the futurp Journalists were being trained. An other thing that proved interesting was the exhibition of books by Co., lum bia men in the library
 In the evening the alumni met in the commons for a bcefsteak dinner, after which they went to the gym nasium to see the basketball game.
