j nuseumns, aatural history museunis and other special museuis, but the late Julius Rosenwald. recognized the cultural influence of industry, and of science and engineering which are theé basis of ail industry,. and 'he made possible 1this -institution Which .will trace the technical progress of man fromn primi*tive times to tbe present. MUum ofNew Âge Inutilprocesses an d scientific discoventes are largely mystroust the. average person because they are complicated and because they are car- ried. on in large milis, factories ,and universities -to which the public bas littie access. lInthis museum the public, * is given a chance to understand, clearly, by personal contact, just how things work.. Here the eternal question of the machine age, uHow and why doesl it work ?" is answered. It as truly a mtuéumn of the flew age; an aIge ini whicb things move and change. The museum is boused in the build- ing fonmerly known as the Fine Arts. building of the World's Columbian Ex- position of 1893, which bas recently been reconstructed. in Bedford lime- stone. lIn the opinion of Auguistus St Gaudins, this building "is the finest *thing done since the P-thenon.,ant! pie of the Chicago district anay have pride..Etr unl itemas ntir aml A large section of the exhibit space, in whicb visitors snay spend twb to five hours, was opened to the public in July, 1933, and since that tiape over 400,000 visitors have enjoyed the exhibits whichi are representative of what the mnuseurn exhibits will 'ultimately be. The pres-,l etitation isi equally interesting to men,1 women and children. The building is open, without charge, f rom ten a. mi. to six p. nm. seven davs eacb week. At the close of A Centuryi of Progress the majority of the out-i standing exhibits which fal ithin the1 equipanent. This hoist -was used for the, past nine years to hoist coal at Johnson City, Ill., and in the muséumi it is operated exactly as it was at thie mine. As a visitor you may enter tbe coal ýcage, the mineirs' elevator,,and as the attendan t. closes thiegateý, the cage, will descend seemingly' 500 f eet into the ground. You, will smell the dank musty odor of the mine, you. wiII' feel thecol bastofair bit your face an al the, senses will proclaim a coal mine. You .will leave the cage and, see and hear a large, machine,, known as a. ro- tary> dump, pick up loaded coal cars andturn them upside down; see the typical pumping equipme nt of a mine and learn froni the mîiners, attend- anits wbo bave spent two or1 more years in coal. mines, the geôlogy of coal, the methods, of mining used ini Illinois,- and somie of. the special problems which confront the engin- eer in wresting coal f rom the. earth. You will then ride for. tbree or four Iminutes in a minle train with the ic- coenpanying noises and sensations you would have in riding three-quarters of a mile into the mine to the working faces of coal. Ilere you will leave the cars and see men at wvork using the large machines used today in a anech- anized mine. No Danger-No Dirt Your thirty-minute trip througb. the mine wiil be realistic iD every particular without the danger and diii found in a real mine-and here you will appre- ciate some of the problenis confronting' this basic industry. Attendants in the museum arecflot guards but a group of young men, each expert in bis particular field, who will aid the visitor in understanding and'iii- tepreting the exhibits. Each attendant will conduct, witbout charge, interest- ing and ively tours tbrough the ex- hibits at frequent intervals. Here, you will see the fossil évidence supplied by the geologist to prove that coal came, f roni vegetable matter which grew, roughly, 250,000.000 years ago; you may smell the perf unies made 1w,ý the chemist. from coal: operaie a miniature automatic stoker f or a locomotive; see , how a . spinnitio T/he hoi.rt equip ment and thse laadfrome of the Muieum's fuit *ied o/'eratieig bitu-pinous coal mine exhibit. gyroscope is used on board ship to dampen the rolling motion dite to waves; clmb p and look into the gondola whicb .housed Commander Set- tie and Major Fordney in 'the recent. record brealçing flight to the strato- spiiere; seec the applicationi of the pbcto-electre >cel to the sorting of Iabeled and unlabeled cans and its use in transmitting photographs by wire (the actual equipanent used ini trans- mitting pictures of Lindbergh f rom Paris to New York in 1927); push a button and see the operations of a tor- pedo as used in the navy; sec and hear a deep sea diver in a diving suit in a tank of water burn tbrough a bar of steel; operate the "Rocket" locomotive of. 1829, the grandfather of ail loco- be maintained which will allow the staff to arrange exhibits in historic order and to show the fundaniental basic 'principles of each subject f.rst and the more conmplex later.
