Vol. XXI. No. 4. gear, Kent on that Talk offifi. Series Civil Engineering Series Begins Saturday The ninth and last program in a series 0f applied scienti~ fic broadcasts concerned exclusively with electrical engineering and touching upon the social and econom- ic values of the many contributions of things electrical to our every day life, was “Sound Description of Prin— ciples of Radio Engineering." The program was presented March 5, over Station W.C.F.L. at 6:45 p.m. under the direction of Alexander Schreiber, publicity director of Ar- mour Tech. Guest scientists were Arthur William Scar, Assistant Pro- fessor of Electrical Engineering at Armour and Earl Lewis Kent, In- structor in Electrical Engineering and Director of Television Research at Armour. Explain Frequencies Professors Sear and Kent explained that the stimulus for sound is a body in a state of vibration. The pitch of the sounds we hear is dependent upon the frequency of vibration of the stimulating source. Speech requires a wide range of frequency in the formation of words. Therefore, transmitting vocal sounds by radio, it is necessary to convey all of the frequencies of the voice at the same time in order that the listener may be able to distinguish sounds produced by the speaker. Mr. Kent explained that the es- sential frequencies for an intelligible speaking range are from 100 to 2500 cycles per second. Musical frequen- cies range from 35 to 6000 cycles per second. The ear is most sensi- tive to a frequency of 1000 cycles per second. Prof. Scar said that a wider band of frequencies brings out the naturalness and color of tone, and that because of this fact, meth— ods of recording: and reproducing music and speech have been greatly improved. New Series Starts Saturday By the use of a special filter, fre- quencics below two hundred cycles per second and above 3000 cycles per second are filtered out. The voice of a baritone can be made to sound like a bass. Similarly, the tone con- trol of a radio eliminates high fre- quencies and emphasizes the bass region, and vice versa. Next Saturday, a new series of re- lated educational broadcasts con- cerned with the field of civil engi- neering will be presented over sta- tion W.C.F.L. at 7 o’clock. Dr. L. E. Grinter, Director of the Civil En- gineering Department and Dean of Armour Teeh’s graduate division, and Mr. William M. Simpson, also of the Civil Engineering Department, will be guest scientists. Players Give Party as Members’ Reward As a celebration of the financial success of their recent production, the Armour Players Guild decided to give a party. At the post-production meeting held recently, it was decided that the members should have some measure of return for allktheir ef- forts in the form of a merry good time. After discussing the problem over and over, the date was tenta- tively set for either the 18th or 19th of this month. As far as is known at present, the party will be held in the Mission building. The Guild will have as its guest of honor the lovely young Miss Kavan— augh, who so ably played the female part in their last play, “The Marriage Proposal." She will be presented with a gift from the Guild to show the appreciation she so much deserves. A committee has been appointed for the selection of an approriate gift. The last party given by the Guild some time ago was quite a memorable event. The members attended a per- formance of “Tovarieh,” enjoying a pleasant evening: All concerned are looking forward to the coming party with keen anticipation. Experts Contribute to Armour Engineer The March issue of The Armour Engineer promises to be an interest— “my,r one. With a circulation of more than twenty thousand copies, this magazine will be ready for distribu- tion in about two weeks. As usual, the 'articlcs are written by men who are authorities in their respective fields. large companies, and a noted psychol— ogist are among the contributors. Their subjects will be as follows: “Transoceanie Flight,” “Radio in Do— mestic Air Transport,” “Bituminous Coal, Our Major Source of Energy,” “Commercial Application of X-Rays," “Soot Comes of Age," and “Suiting the Man to the Jo ." Student Speakers Compete at A. S. M. E. Assemblies Two student speakers, A. N. Schriebcr and S. Gryglas, will be heard by members of the Armour branch of the A.S.M.E. this Friday at 10:30 in Science Hall. These talks will be two of a. series given in competition for the choice of delegates to repre- sent the Armour branch at the con— vention which will be held in Mil- wankee April 18th and 19th. Here the delegates will campetc for vari- ous prizes. Gryglas will speak on “Strato- sphere Flying” and Schrieber will probably talk about some trends in railroad transportation. Movies were shown at the meet- ing last Friday in the Automotive Laboratory. The Budd Body Corpo- ration prescntcd two movie reels and the Standard Oil Company gave three reels dealing with the distillation of crude oil and the lubrication of cars. Alpha Chi Schedules Pledge Fimohar and Yul—Chapter Dance Prospective pledges to Alpha Chi Sigma, professional chemical fratern- ity, will be guests at a smoker to be held tomorrow evening at the Pi Kapp house. Also on the Alpha Chi schedule is a trl~chapter dance with Northwestern and Purdue to be held at Northwestern's home hall, Satan day, March 26. These events fol‘ low “Armour Night,” held last Tucs- day by the professional chapter. The smoker, planned for the chap- ter’s own rooms, will be held in the Pi Kapp house instead, due to the extensive renovation being carried on by the fraternity. Ping),r pong, poker, and pool will be offered as a pleasant diversion from the Armour routine. Bids for the dance have been dis- tributed among the members. Ad» Vance returns indicate that almost the entire chapter will be present. Thorne Hall will offer a pleasant at- mosphere. An excellent orchestra, ample parking facilities, and delicious refreshments will contribute toward making the evening a pleasant mem— ory. At the last meeting of the fratern- ity, P. J. Peltier was elected to rep- resent Alpha Psi Chapter at the na- tional conclave to be held in New Orleans in the near future. He will spend an entire week in attending the meetings and conferences. Fresh Co-op Class Elects Officers; Olson, President Mr. L. J. Lease, coordinator of the co-operative courses, called a meeting of the freshman co—ops on Monday, February 28. The purpose of the meeting was to form a class organ- ization and elect class officers. M. Lease spoke briefly preceding the election. He related some of his experiences with leaders in industry, concerning the co-operative courses. He said that the co—op courses could fill a long-felt need in industry for far-sighted engineers who know their business from the ground up. The election was then held and the following were selected to load the group: Kenneth Olson, president; Robert Warner, vice-president; Wil- liam Skene, secretary; and William Dienhart, treasurer. Three engineers, two presidents of‘ Armour Institute of Technology, Chicago, lllinois Night Students Elect Permanent Officer Walter Koch, recently elected pres- ident of the Evening Division Stu- dent Association, assumed the reins at the first executive meeting of the Division held last Saturday. A mem~ bership drive was formulated which ishould, at its conclusion, bring prac- tically all of the 2,000 night school students into the fold. The first steps toward this end will . be the dissemination of Division news and the distribution of membership cards. A fee of fifty cents wll be collected from each member to cover incidental costs of propagation. Probably one dance will be included in the forthcoming program of events. The officers recently elected are as follows: W. E. Ifoch, president; A. Rulis, executive vice-president; H. A. Lynette, secretary; and Leo F‘aitel- son, treasurer. The divisional offi- cers also elected at the same meet- ing are, for the Monday-Thursday section: R. J. Wnukowski, vice-presi~ dent; C. Bielko, recording secretary. Elected for the Tuesday-Friday sec» tion were; A. L. Simandl, vicepresi— dent, and J. Sabo, recording secre- tary. T. Deusner and W. Cook were appointed to the membership commit- tee. At some future meeting the other three vice—presidents, provided for in the constitution, will be elected. Comp Club Arranges Second Annual Dance; Rhythm by Prindl’o Band at Graemere The dance committee of the Co-op Club has completed the details of the second annual Co-op Club dance, and bills will he on sale this week. The (late selected is Friday, April 1st, and the place is the bcautiful grand ballroom of the Gracmcrc Hotel, at Human Boulevard and Washington. The club was fortunate in obtain- ing the services of Mickey Pl'imll‘n lino orchestra. Mickey features two talented soloists, so a highly enjoy- ablo eveningr of dancing is in store for all who attend. Bids; will be on sale by the middle of this week and can be obtained from club members or from Miss Al- berta How in Mr. Lcase's office. The price is $1.50, and the number of bids is limited. Prizes of one bid each will be awarded the two students who sub» mit the first and second best posters advertising the dance. These should be submitted before the end of next week. Frat Council Passes on Freshmen Week with Decisive Vote Freshman week, a combined orientation and fraternity rushing- week for incoming freshmen, was voted upon and passed by the Inter fraternity Council when they held their regular meeting last Wednesday evening at the Triangle House. This clinching vote had been deferred for months due to the opposition of sev— eral of the fraternities. The final vote was seven to one. A bill was also suggested giving the Inter-fraternity Council an operating fund. At the start of each year every fraternity member and every pledge will pay fifty cents dues to his house which will turn it over to the Council. This action gives the Council power to act on decisions without special assessments from each of the fraternities. It enables cups and trophies to be purchased for in- ter-fraternity competitions, and it will also go toward the publishing of the fraternity handbooks. The freshman week as it is plan» ned will occupy the first week before school in the fall semester. The first day will probably be devoted to reg-i- strations and psychological examina~ tions. The fraternities will sign the freshmen during the first days and have the rushing dates during the rest of the week. At the next meeting to be held at the Rho Delta Rho house, the final details of the freshman week will he completed.

RosenwnlolIl/fuseum @pens West Wing Prof. Spondegr’s Models on Exhibition One of the greatest scientific and industrial museums of the world be- came a step closer to completion, when two miles of exhibits in the west wind of the Rosenwald Museum of Science and Industry were formal- ly opened Tuesday, March I. The opcning‘ ceremonies, which were attended by many prominent men, were presided over by chair— man‘Ii‘iufus C. Dawes, president of the Century of Progress, and Dr. Phillip Fox, director of the museum. Members of the Armour ’l'cch faculty who were present were actinz.r Pres. H. ’l‘. lleald, Dean B. B. Freud, Dean L. E. Gl‘inter, Dr. L. R. Ford, Dr. E. H. Freeman, Mr. J. G. Potter, Pro— fessor W. A. Spencer and Mr. G. E. Ziegler. A feature of the new exhibits is a well selected group of mathemati- cal models designed and built by Pro- fessor Spencer, impressing; upon the mind vivid picture of type curves, areas, surfaces, and solids. This group of models is unique in ma- terials and design. Tempered prest— wood, plastics, chromium, and silk thread, coupled with bright colors make the models distinctive. Other exhibits include displays, many of which were on exhibition at the Century of Progress Exposition. Professor Spencer's models were on exhibition, from July to October last year, at Columbia Univer— sity in New York. These same models were on exhibition at the meeting of the American Association for the Advancement, of Science and Asso~ ciatcd Societies at Indianapolis Dec. 27-30.

Prof. Penn, Group Leader, at U. of l. Survey Conference Last Friday and Saturday, March 4 and 5, a surveying conference, sponsored jointly by Department of Civil Engineering of the University of lllinois, and the Illinois Society of Engineers, was held at the univer- city. The conference, attended mainly by licensed surveyors of the State of Illinois, had a representative from Armour Institute in the person of Professor J. C. Pcnn of the civil ens-i» nearing department. He was the leader in the discussion of the now Registration Law and other phases of land surveying. Other important dis" cussions dealt with recent happoninus in the fields of land, highway, rail~ road, and topographic surveys. interesting discussions were given on statewide plane coordinates, which take the higher mathematics out of precisely controlled surveys. Talks were also presented on the lat- est methods of aerial photographic surveys. Traction Authority to Talk at WSE. Meeting Friday Next Friday at 10:30 in Room B- Mission, the Armour Chapter of W.S.E. will present Mr. Robert King:~ Icy, director of the Chicago Regional Planning; Board on “Regional Plan- ning in Chicago.” Students in all departments will find the lecture of exceptional inter- est becausc of the relationship of the subject matter to the current traction problem in Chicago. Among the many interesting: phases of the subject will be a dis cussion of the proposed super-high- way for Congress street. It is generally known thut Chicago is far behind New York in that we have no elevated highways to speed up transportation to the outlying dis- tricts of the city. Tuesday, March 8, “938 Wow llroah Class 1 rings Enrollment 1 to Alli-slime lllgh Mechanicals Lead Dilber- Departments in Number Information made available this week from the registrar’s ofi'icc re- vealed that 75 freshmen entered Ar— mour in February, bringing,r the day school enrollment at the present time to 972. This is the largest enrollment in the history of the school. Upward trends were exhibited in all depart- ments with the mechanical and chcm‘ ical departments lending. The lat;— ter department showed the greatest single increase when approximately one third of the number entering: in February, signified their intention of becoming members of the chemi— cal engineering department. Chemicals Next The mechanical engineering de- partment leads the list with an en- rollment of 295, followed closely by the chemical department with 264. Other enrollments are electrical engineering~ 158; civil engineering,‘ 95; architectural, 84; fire protection engineering, 54; and engineering sci~ once, 16. Enrollment by classes showed that there are a total of 324 freshmen. This is the largest freshman class over enrolled at the Institute. The sophomore class has 262 students also an all time high. There are 166 third year men and “38 seniors en— rolled. Miscellaneous enrollment rc— vealcd 44 part time students and 18 graduate students. Upward Trend Revealed Other interesting data compiled by the registrar’s office since Sep- tember 1920 revealed the average loss of enrollment of each class per semester; the per cent of decrease between the first and second semes- ter is 9.8%; between the second and third semester, 6.0%; between the third and fourth semester 5.7%. The largest percentage decrease occurs between the sophomore and junior year with a loss of 14.9%. Between the fifth and sixth semester the rev duction is 1.2%; between» the sixth and seventh somestcr.9.4%; and the seventh and eighth semester, 2.3%. Statistical data of the total regis- tration each year since 1926, had nhown only a slight trend upward. Up to 1926 the enrollment increased to an average enrollment of 750 stu- dents. From 1926 to 1935 it had gone upward to an average of 800. This last year number has been the peak with almost 900 students for the September enrollment. The figures given in the above data are exclusive of the students enrolled in the cooperative course. The co« operative students number well over (Continued on page four) ll.
