@pen idioms ides Largest grown? Ever @Attend They came, they saw, but what they did afterward we can not say. At any rate, Armour has had an- other very successful Open House. Everyone present apparently had a very enjoyable evening for them- selves wandering among the many technical exhibits. No official count has been given out to date, but the total attendance is estimated at over 5,000 people. As a result of the huge crowds and increased interest it is hoped that in the future Open House may be extended over more than one day. Organic Lab—A Hit Among the most interesting and best regarded of all the various ex- hibits was the organic chemistry dis— play, J. R. Meyer is to be congratu- lated on his excellent managing of the entire program which included several topics of importance. One of the main subjects was the polaroid disc exhibit to demonstrate the pos- sible use of polarizing glass in the headlight lenses and Windshields of automobiles. The effectiveness of polaroid was shown in quite a strik- ing fashion by having a bright light placed behind the two disks and then rotating one disc. When the polar- izing planes came into mutually perv pendicular positions the light became a deep purple with no glaring prop— erties at all. Motorists were especial- ly impressed by this as night glare from headlights is one of the great est hazards to drivers. Antiscplies Displayed On the other side of the lab was a display of several modern antisep— tics. Henry Newman was in charge of this and was engaged in the preparation of Chloramine-T, sold under the name of Chlorozine. Others of the bug-killers on display were metaphon, a mercury com- pound, and a benzene derivative. The preparation of aspirin, titration in- dicators, perfumes and essential oils were also going on. The usual odor of nitro-bcnzene that prevails in the lab was overpowered by the vapors of oil of cloves, Wintergreen oil, and several other pleasant smelling sub— stances. Taking a drop down to the third floor, the freshman lab was working at the usual analyses. Osmosis was neatly shown with a parchment bag and a sugar solution, while the spec— tacular hydrogen fountain was dem- onstrated by means of the clay cup and Kipp generator. Many of the vis— itors expressed considerable interest in these exhibits of molecular phe- nomena. (Continued on page two) Senior’s Farewell §moker Ar Lawson ‘Y’ Thursday As a finale to its four years of so— cial life at Armour, the senior class will hold a farewell smoker at the Lawson Y.M.C.A. Thursday evening, May 19. An interesting program has been arranged to entertain the class from 8:00 to 11:30. Professor J. J. Schommer, referee, good fellow, after—dinner speaker of wide reputation as well as professor of chemistry, will “talk to the boys” as a part of the program. Several reels of movies are to be shown and arrangements are completed for cards and tables. R. Worcester, chairman, has made it possible to use the swim- ing pool at no extra charge. Towels will be furnished and suits will be unnecessary. All seniors attending will of course have free smokes (nickel ci— gars?). The tickets are only fifty cents and may be obtained from mem— bers of each department. Inasmuch as this represents the last chance for the graduating senior class to gather together, it is suggested every man of ’38 be on hand for one swell eve- hing. fiunior Week Takes Leave With Memorable lunior intormal Friday Night With the moon flooding the drives of the Olympia Fields Country club, the Armourites brought a close to the Junior Week festivities with the Junior Informal. Upon entering the club, the danc- ers were faced by an immense lounge, colorfully decorated, and furnished with thick carpets and divans. The lighting was soft, but colorful, as the many spring colors passed beneath them. Walking through the lobby of the club and into the ballroom, the en— gineers were thrilled by the spacious room with a polished floor. It was not long before the ballroom was filled with dancers; not crowded, but just a gay crowd. Gay Claridge and his popular or- chestra furnished the dance music from nine until one. Attending the dance were the fol- lowing: Professor and Mrs. Hen- dricks, Mr. and Mrs. Allison, Mr. Schrciber, Miss Nitchin, Mr. Ahern, and Mr. Potter. The engineers and their girls were very proud to display the small bracelet that. was attached to each block and silver bid. The commit- tee in charge of the dance arranged all the details to have this year’s Junior Dance, not only the most suc— ccssful, but the gayest dance of the year. The chairman of the enter» tainmcnt committee, B. Anderson, is responsible for the success of the dance with the assistance of l. Foot— lik, E. Mitchell, and D. Jacobson. Sophs Win hush 9-7; Rotten Egg Barrage Upsets brush Plans In the hardest fought and closest battle held in many a year the sopho- mores defeated the freshmen in the annual rush by a score of 9-7. Be- fore the fight there were many small and inconsequential fights, but most of the underclassmen saved their en— ergy for the rush. It was no uncommon sight to see both freshmen and sophomores run“ ning around without pants or shoes. The rush began at the drop of a handkerchief and ended at the firing of a gun at the end of ten minutes. There was a newsreel truck on the lot taking moving pictures of the fight. Besides the newsrecl camermen there were many other people taking candid shots of the battle. When the handkerchief was drop- ped the sophomores advanced on the bags in the center- of the field, and the freshmen, with a barrage of com- paratively fresh eggs. After the egg barrage the upperclassmen had a lltr tle egg-tossing contest of their own with some not-so-fresh eggs. As a matter of fact the eggs were so “un« fresh” that two chicks hatched out. At the close of the rush the fresh gave a cheer for the sophs, and the sophs gave a cheer for the fresh. A bonfire was made out of the bags and both classes held a snake dance around the fire. After it was all over there was much handshaking and verbal bou- quets were thrown around and both classes parted friends. Twenty-five ‘Nighrhewks’ Visit Edison Power Plant An inspection trip of the Fifth Street Power Plant of Commonwealth Edison was taken last Saturday morning by a group of Armour “Nighthawks.” The group was con- ducted by Mr. Frederic Oakhill, hon- orary director of the evening stu— dents’ association. Inspection trips are a regular part of the activities of the “Nighthawks.” This one was limited to twenty—five members; the first to apply were ac— cepted. "Nighthawks” Hold Dance Saturday Next Saturday evening the “Night- hawks" will hold the first dance since their organization. At 9:30, Lou Brownie’s orchestra will begin the evening’s dancing for the 150 couples in the French Room of the Drake Hotel. Dancing will continue until 12:30 for the cozy group. Honored guests for the evening will probably include President Heald, Prof. More- ton, Mr. Oakhill, and Mr. Munduy. The committee in charge of the dance includes H. Lynette, A. Simandl, and L. Faitelson. All ar- rangements for the dance have been made by the above men. The bids have the Armour “Nighthawk” on the front cover. The inside of the bid is artistically set with gold letter- ing on white paper, while the outside flaps are of a bright gold finish. The dance is to be purely a social affair and will not be operated for profit. It is planned by the group to be an annual affair. [Delft ‘ifilass-pushers’ Win inl-eriraterniry Marbles Inter-class and interfraternity mar- bles, the new addition to the Junior Week family of events, went over with a bang. It was surprising the enthusiasm with which this battle of knuckles was accepted; everybody seeming; to want to be on the teams. The Delta had a fine aggregation of glass—pushers entered in the inter— fraternity contest, and consequently won. with a sum total of fourteen marbles. Runners-up were the Phi Kaps, who connected for a count of eleven mibs. Junior-senior marbles also brought out a large crew of former school- yard champions. The seniors trounced the juniors badly by the score of twentyseven to eighteen. The high man in both competitions was junior marshal Tom Clark. In the interfraternity competition Clark managed to knock out seven of the fifteen marbles competing against six other knuckle-downers. New President Photo by Grunwold Mr. H. T. Heald, President of Armour Institute of Technology, reading one of the many congratulatory telegrams he received last Wednesday and Thursday. firms Buy drovides Metric Atterrroouter Student Body Last Friday, the annual Circus Day and Pageant, given by the vari- ous fraternities, in cooperation with the four classes as a part of Junior Week, was held. The award for the best skit put on by a fraternity went to the Phi Pi Phis. Their efforts, opening the procession of skits, was titled “Snow White.” Their scenery for the production was a synthetic fairy castle. The witch, Snow White, the fairy prince and the seven dwarfs were all aptly played. Sound con— sisted of a chorus of offstage voices who fitted parts of various songs into each situation instead of actual dialogue. Pi Kappa Phi followed “Snow White” with the “March of Armour.” This playlet dealt in a humorous way with the life at Armour, from the days when “thirty-third and the tracks” was the gold coast of Chi» cage, down to the present day. Sound was enhanced by a public address system. Theta Xi presented “Six Stages in the Life of an Armour Student.” It depicted the freshman student with his 24 inch slide rule clear through to his senior days with a six inch slide rule, and also beyond his grad- uation when he reached his ultimate ———a job with the W.P.A. Rho Delta Rho painted a vivid pic~ ture of school life at Armour with coeds present. It stressed the point of library fees, with books that could be taken out for one minute, 30 seconds, 15 seconds, and finally books that were due in one second. The poor student finally had to re~ sort to turning his shoes, shirt, pants and underwear over to the cashier to pay the enormous fines. Triangle fraternity presented “Mr. and Mrs. Dope and Their Son Dopey," and in a novel way showed little Dopey being put through the mill with tons of math., physics, me- chanics and, what not. It showed how the poor student’s father pays and pays—$5,000 for the crippled teachers' fund, $6000 for activity fees," etc. Delta Tau Delta presented “Ar- mour Hall Tonight,” and mixed in with it various news events of the happenings of students.

Armour chapter holds its semi- annual initiation ceremonies. The nine new men. who are completing their pledge duties and preparing for their examination this week, are as follows: L. A. Bain, E. D. Gryglas, W. A. I—Iofmann, E. N. Isakson, and J. J. Ratto, juniors; R. Collopy, J. Fahey, E. Gruca, and R. Petri, sopho— mores. After the initiation ceremonies a supper will be held for the new and old members in a private dining room at De Met’s. The group will then spend the remainder of the evening at a play. School To Award Ten Scholarships baturday Saturday, May 2], the annual scholarship examinations will brim: 198 outstanding students of the Chi— cagolund area together for the com- petitive examinations. Ten scholarships will be awarded on the basis of (1) personal interview (2) written examination. The per- sonal interview has been made by the members of the scholarship commit- tee, which is composed of the follow- ing members of the faculty: Bibb, Davis, Kelley, Manley, Sear, Seegrist, Sprag‘ue, and Winston. The members judged the students on personality, scholastic record, extra-curricular ac- tivities and general litn s‘ Those students residing in distant cities have been interviwcd by Armour graduates. The competitive examina- tion will be given under the spon- sorship ol’ the principal of the school which the student is attending, thus eliminating; the necessity oi‘ trans— portation to Chicago. The Junior Marshalls will act as ushers and proctors, as in the usual practice. The fraternity chapters at Armour will act as hosts to the scholarship students. Wei/5 Discusses Aviation Top/C “Lighter Than Air Craft” was the subject discussed last Saturday eve- hing;r by Professor M. B. Wells over station WCFL. The program was the ninth of the civil engineering section of the applied science series spon- sored by Armour Institute. In presenting: his topic Prof. Wells first explained the significance of his topic and its meaning: He then spoke of the two essential i‘caturesma space occupied by a gas lighter than air and an envelope to enclose this gas. Those two features in the proper pro— portions to give a resultant liftinp; force are the basic constituents of any air crai’t. Hydrogen and helium were then spoken of in terms of lifting ability, advantages and disadvantages. One thousand cubic feet of hydro- gen is capable of lifting seventy-five pounds, whereas an equal volume of helium can lift seventy pounds. Since hydrogen is explosive, however, it is not employed as extensively as is helium. Continuing, Mr. Wells explained the difference between balloons and dirig‘iblcs. “A dirigiblc,” he said, “consists of a balloon or balloons equipped with control devices and with power that enables them to be navigated in any direction and at different altitudes. A free balloon, on the other hand, can be controlled only with reference to altitude, the direction of its flight being: depend- ent upon the direction of the wind at the altitude determined by the pilot.” The balloon was then spoken of in reference to its application and navi— gation. Wind directions are found by a so-called pilot balloon, while wind velocities are determined at the various altitudes. Commercially the balloon is practically useless. Today its applications are only in the field of sports, where it represents the highest test of a pilot’s skill, knowlv edge, and courage, and in military organization, where it acts as a train- ing course for men. Three types of diri-gibles were then spoken of: the non~rigid dirigible. in which the power car and space for passengers are combined and $115. pended from a gas cell, which ’ of streamlined shape; the seini»rigid, which has a similar ens cell but is still‘encd or braced with a girder~ (Continued ma page four) Medial Receives flouprotuiotioas For New titties Surrounded by congratulatory bou. qnets, President 11. T. Heald assumed the duties of President of Armour Institute of Technology last Tuesday evening, May .10. The office. which President Heald has been adminis- tering; in the capacity of acting Pres» ident since last October 12th when Dr. Willard E. ‘Hotchkiss resigned, was ui‘ianiuiously voted to him by the Board of Trustees. Scores of telegrams congratulating his appointment are being' received from well wishers from all over the country. The President’s Office had been receiving visitors all day Wednesday and was jammed Open [louse Night with visitors extending their congratulations. Vocal Endorsement The popularity of President Heald amour," the members of the faculty and student body was demonstrated at the Annual Spring Concert of Mn- sical Clubs and lnteri‘raternity Sinp: by an uithusiastic ovation given him as he was lntroducui by Head Mar- shal Junicck. While no definite plans for Al‘- umur’s future has been announced, a tentative remodeling program is said to be considered.

Tibbale Made Dean Dr. 'l‘ibbals received the appoint- ment of" Dean of the undergraduates at the same time that Dean Heald was made president. When asked concerning his appointment Dean Tibbals commented that his duties would no on as ever despite the change in title and that he is very content and happy at the opportun— ity oll’erod to serve Armour and to work with President l‘leald. Dr. Tibbals came to Armour in 1.908 from the University of Wiscon- sin, where he was an assistant in— structor in chemistry from 1902 to 1000. He. attended Columbia from 1899 to 1902 as an undergraduate and then went to the University of (Continued. ml. page four) Phi Kappa Cop Sing At Spring Concert Breaking the threeyear reign of Pi Kappa Phi, Phi Kappa Sigma won the inter-fraternity sing last Thurs— day night. Their winning songs. were “Loyal Sons” and the “Marching; Song." The announcement was made by Prof. Finnegan. Presentation of the award was postponed until the cup arrives, because Pi Kappa Phi has won permanent possession of the trophy. At this time President l-leuld was introduced for the first time at a public assembly. He was greeted by a huge ovation, and the entire stu. dent body honored him by standing. The orchestra and aloe club ofl’ered several numbers before and after the sing. The solo work of R. Vnnde~ kieft, ’l‘. Yeaklc, E. hairy-l, and G. Danforth was featured by the group. This affair, with the Alumni Ban— quet, will have concluded a very suc- cessful season for the musical clubs. Included in the year were two radio broadcasts, one of them over the (‘olumbia Broadcasting System chain. ’l‘wo trips were also taken by them. one to La Grange and the other to Ksukukee.
