THREE CENTS THE MARCONI SYSTEM Wireless Telegraphy Explained by Professor Morse How Mes sages are Sent Across the Atlantic. The following description of the Marconi system was omitted from Professor Morso's leoturo yosterday morning, due to a lack of time. The diagram distributed yesterday represents approximately the ar rangement employed by Marconi In his famous tians-Atlantlc experi ment. Information obtained since the diagram was drawn shows that at tho English end of the trans mission areal wires wore supported by twenty poles, each 210 feet in height. Not all of the wires were, however, used on that occasion. It also appears that, due to its greater sensitiveness, a telephone receiver was employed in place of tho Morso sounder at M. The altitude attained bv the klto at tho St. Johns end, while signals were being received was 400 feet. Taking up first the transmitting or Poldhu station G, Is a plate of metal sunk In tho ground, to which lit. attached a copper wire, the wire terminating at Its other extremity In a solid brass ball P, an inch in diameter. Opposed to this ball and about half an inch from it is a simi lar brass ball, tho wire from which loads olthor directly to tho top of a high polo or up a kito string. The preoiso length of this aerial wiro Marconi early found to bo of vital importance, as will bo explained later. All auxiliary apparatus shown at the transmitting end Is merely employed to cause sparks to jump across between the brass balls. These sparks lly across lu a rapid torrent, which lasts a longer or shorter time according to whether a dash or a dot is to bo expressed. The sparks are produced bv a coil of very many turns of fine and highly insulated copper wire (J, wound upon a bundle of iron wire I, much as thead Is wound upon a spool; tho two ex trometies of the coil O heihg attach ed, one to each brass ball. The spark'ng energy produced in tho coll O is due to a second coll Q of eonrso wiro of few turns, wound up on" tho same bundle of iron wires, Q In turn deriving its supply of electric energy from galvanic battery V, where zinc Is dissolved In acid. It is necessary that the How of electric ity though the cotl Q be rapidly in torruptod, a function which might be performed by an ordinary electric belt Tho sending- key-S-is-a fam4Har object to any ono who has watched a telegraph operator at his work; In tho present Instance, when S is de pressed, T begins to buz and sparks continue to fly botwon tho balls until it is released.

From February 20 to 23, at York, will be held tho twenty-second an nual stato convention of the Nebras ka Young Men's Christian Associa tions. The preparation fjr this con vention aro In charge of the state committee of the Y. M. C. A. of which Prof. H. U. Ward of the Uni versity Is tho chairman and W. J. Hill of Lincoln, treasurer. It is expected that several hundred delegates will bo In attendance, re presenting tho nlno city and eleven collego associations in the stato. The citizens of York have, through a special committeo, arranged for tho froo entertainment of all accredited delegates. The only expense to dole-J gates will be railroad faro a special rate of one and ono third faro having been secured on all roads. State conventions of this kind are for the purpose of consultation and conference on Association's methods and problems; reports from the dlff erent points in tho state, a rev cw of tho field and plane for operation in the future. There will be strong addresses Influential men in tho state, also some association leaders outside Nebraska. Tho results received from attending this convention will well repay tho effort; those attending such conventions in tho past havn consid ered tho time well spent. Any mem ber of tho University Y.M.C.A. who will goas a delegate should hand his name to Mr. Hubbell as soon as pos sible. It is expected that twenty men willattend from tho University, and thero is still room for more. A game of basket ball will bo played during tho convention between the O'maha and Ldnooln teams. Chancel lor Andrews appears on tho program with tho subject, "Christian Citizenship." WILL EXHIBIT WORK. by by of DEAN SANDERS-YALE. A t 4 o'clock Sunday afternoon Frank K. Sanders, Dean or Yale Di vinity school will deliver an addross in tho University chapel. All stu dents and friends, both ladles and gentlemen aro Invited to this meet ing. This Is an opportunity to hear worthy man from the oast. Lot all the students turn out and hoar him. Frank D. Sanders who is to address the Y.M.C.A. meeting next Sunday aftornoon was at Mnlnesota Univer sity recentlv, tho dally of that school speaking of his visit said in part: "It Las been some little tlmo binco the University of Minnesota had the pleasure of being visited by any 'wise men lrom the East' but yesterday it hadthis pleasure11 TJeah TrrahTf Sanders of the Yale Divinity School, who Is in the city, was present at chapel and spoko to the students. Dean Sanders is himself a western man being a graduate of Ripon Col lege, Wisconsin, and feels much in terested la western Institutions of learning." " Several Departments to Show Their Work To-morrow Bhopa and Laboratories Will be in Running Ordor. Tho engineering departments of tho University will ondeavor to show tho public tho character of " their work, tomorrow afternoon. Shops, lanoratories, boiler houses and en gine rooms will ho open and plenty of students will bo on hand to an swer questions of tho Interested peo ple. Nothing special will bo at tempted In tho civil and mechanical engineering departments, except that tho shops and laboratories will bo in operation so that visitors may get a clear idea of how the work Is carried on. It Is probable that tho fou-idry will be running and some casting done. Tho domestic science department will make a special ellort to exibit Its work. The laboratories, In Me chanic Arts hall, will bo open to visitors from two to five o'clock. Ar rangements have been made for an elaborate exhibition of all foods, how ever. Bread-stulTs, In all its forms of preparation, will be exhibited In stead of a display of cakes, pies and other pastries. This, It is thought, will bo m"re satisfactory than to supply visitors with samples of var ious datables. An Interesting feature will he some experiments with tho yeast plant, showing tho conditions under which It works best and tho results obtained. A model table will be spread to show tho proper position of dishes and tho appearance in general of a prefectly arrauged dining table. Ow ing to the fact that the commence ment exercises take placo tomorrow night, the electrical exhibit will bo given tonight. No pains aro being spared to make this a most satisfac tory exhibit. Tho armory, where it will bo held, was given over to the engineering students yesterday morn ing. The building is being rapidly fitted with tho necessary apparatus and machinery. Commodious plat forms aro being erected for machines and fixtures which aro designed es pecially for exhibiting tho lato inven tions in electricity. Tho cadet band will be on hand to furnish music for the occasion. The opening will be at 7 : 30 this evening and will bo accompanied by appropri ate music. One of to prominent features of tho exhibition will be the fine display in electrical decora tions, In which tho latest effects will bo pioducod. Professor Morso will havo In progress high potential ex prTnTelTtBot COrOOO volts. Expert ments with tho neltz Wave ana the Marconi Wireless Telegraph will be in progress. The electrical weld ing process will bo presented ana ex plained. There will also bo several experiments of tho original Nikola Tasola Multiphase, representing the rotating magnetic field. AN ESTIMATE OF NEBRASKA. One of tho latest additions to tno University liDrurv Is a hook cntltlod "Student Llfo and Customs.'' writ ton by Professor Honry I). Sholdon of tho University of Oregon. It is n urn bored volumo fifty-ono In tho International Sorlos and Is a very comprehensive work on clloge life. Student life is touched upon as found in England, Scotland, Germany, France and American ooilogos ana universities; tho latter boing tho moro fully enlarged upon. Ameri can collogos aro traced from their colonial origin, including their growth, dcTClopomont and ovolutlon down to the present day in all phases of student llfo. embracing debating, oratory, class competition, athletics, fraternities, soclotios and organiza tions of all kinds at all connected with Institutions of learning. Professor Sholdon in the compiling of his material made uso of extensive data obtained ell root from prominent colleges In tho country. On looking through the book wo find a few references' mode to tho University of Nebraska which may bo interesting. Tho customs of hazing and rushing are ceasing although tho class feeling In Nebraska is not on tho decline in spite or tho electlvo system. Tho more substantial elements of student life is found in tho study of debat ing, but Nebraska Is omitted, prob ably for good reasons, in regard to Its leagues for debating and In its pnblic speaking attainments. Iu athletics "Nebraska ranks lowest of all the col leges given in the percentage of stu dents in that field of etiort having a standing of about 7 per cent. Tho average fo: all colleges Is 20 per cont. Tho University of New York average 80. Professor Sheldon dwells at great length on the origin and growth of the collego fraternity Including its purpose, ovolutlon and competition, lie names tho percentage of students, w'io aro members or fraternities in Nebraska at twenty. Other colleges particularly In tho east havo larger percentages running to 50 and in some cases almost to 80 per cent. The book is a very valuable addi tion to publications on college llfo and is both interesting and attractive. The senior laws held another meet ing yesterday afternoon for tho pur pose of choosing the remaining o Ulc ers who woro not elected last Tues day owing to tho lack of time. Tbo following were elected: First vice president, L. B. Fuller, secretary, II. Thomas; class senator, Rotruck. After tho election each olllcor re sponded with a lengthy speech which mot tho hearty appiauso of tho lawyers. Tho quarters of tho Harvard Club in Now Yoric are to bo enlarged at a eost of $105,000. i Ml 1: , "T .1 j "4 P ft mf
