It contains the latest and most accurate information avail- able on what has been accom- plished and what is planned for this Exposition of the greatest era of the world's scientific and industrial history. 15] transportation facilities to and within the grounds, and the comforts and conveniences desij^ned for your service. The Book endeavors to prepare your mind with authentic data and description of buildings and exhibits which, in a plan years ago conceived and faithfully fol- lowed, compose, you will discover, a harmonious whole — the engineered development of an epic theme. It will serve you as a Fair guide and encyclopedia, and, too, it i.^ hoped, as a souvenir that you will treasure. What Is the Meaning oF It All? Millions Are Expended — A Magic City Created — Throngs Come — The World Watches — Then It Vanishes — WHY? From May 27 to November 1, 1933, the interest of a considerable part of the civilized world is focused upon 424 acres of land that lie along the shore of Lake Michigan, edging Chicago. A little while ago this site was placid lake. Now, shimmering beside the water, a dream city is risen. It lights the sky with splendor, yet soon will disappear and be merely a memory. Fivs Short Months of Celebration The immensity of the enterprise might make you ask yourself, What could be so tremendously important that a city and its citizens should undertake this titan task of building, shoulder these infinite details, merely to invite the world to come for a carnival? Leaf the pages of history for the last 100 years. The answer is there. A City Lifted From Mud Only a hundred years ago Chicago was a huddle of huts, hewn of logs, clinging to the shadows of Fort Dearborn for safety from the Indians, and four years after its incorporation as a village, in 1833, its population, conquering patches of dreary swamp, had reached 4,000. Today it is nearly 4,000,000 — 3,376,438 for the sake of accuracy, by the census of 1930 — and growing at a rate of 70,000 a year. Chicago in a century has climbed to her place as second largest city in America, fourth in the world. One thousand two hundred houses of worship pierce her skies with spires — more churches and missions than in any of thirteen of the states — and she is one of the country's great religious centers. She has 6,000 acres given to parks and supervised places of play and 35,000 acres of picnic and playgrounds, as forest preserves outside the city limits, and supports a h ndred or more supervised social centers. Chicago ha:, close to 6,000 miles of streets, 84 miles of beautiful boulevards. Bcnc::th her bustling loop, to which area daily at least 250,000 people come to work or for business, and a million and a quarter [8J more to shop or to visit, narrow-gage trains whisk merchandise over 60 miles of tracks through tunnels to stores and marts. Above its towering skyscrapers, passenger and pleasure aircraft and mail planes go their speedy ways, and Chicago rapidly is becoming the hub of American aviation. Chicago is the greatest railroad center in the United States, 53 trunk lines terminating here. An average of one train every 58 sec- onds enters the city, year in and year out. It is the largest livestock market and packing center. It is one of the greatest grain markets and one of the most important ports. Where, a hundred years ago the trading in furs and the business of trapping them constituted the major part of the hamlet's commerce, today her 10,000 or more industries annually produce a vast variety of wares, whose wholesale value averages close to four billions of dollars. It might well stir the most sluggish imagination to contemplate the fact that Chicago, born in the marshes, and actually raised, some years later, by human energy and skill some 12 or 14 feet out of the mud for a healthful and more solid site, now is the commercial and the cultural capital of a domain of more than 40,000,000 people, residing within a night's ride of the city — a population greater than that of Great Britain or France, equal to Germany's. Chicago stands high in world notice as a medical center. It is the home of six famous libraries. Its Art Institute, which, by the way, located in the Grant Park area north of the Fair grounds, is one of two oermanent institutions included in A Century of Progress proper, is visited by more than a million people annually. The Field Museum, which stands, a $6,000,000 marble structure, at the right of the Fair grounds' North entrance, is rated as one of the world's finest museums of anthropology and ethnology. The Shedd Aquarium, within a stone's throw of the North entrance, houses a permanent exposition of marine life second to none in the world. Chicago has a $20,000,000 home of grand opera. Her Symphony Orchestra, founded by Theodore Thomas, is considered one of the finest. Her Museum of Science and Industry, established by the late Julius Rosenwald, in one of the magnificent buildings of the World's Fair of '93, in Jackson Park, ranks with the world's great museums. The Adler Planetarium and Astronomical Museum, also included as a part of the exposition, is the only one of its kind in America, and only one other in the entire world has its equal in equipment. Chicago is a center of education for the Middle West, a city of many great colleges and universities, enrolling 40,000 students; she has some 40 high schools, and junior high schools, and more than 300 grade schools. So Chicago Celebrates The foregoing tells scantily a few of the things that cause men to call Chicago great. Ride over her boulevards, view her serrated sky- L9J line from her twenty-six miles of lake front, visit her institutions, see Chicago in all her myriad phases of life and activity, and wonder ceases why Chicago, in pride, is stirred to celebrate her own Centennial. This youngster of the Xew World had fought the wilderness and won, and had welcomed peoples of many bloods who came and helped to build. Then came years, of recent memory, when the economic scheme of things seemed to go awry, and the steady march of progress appeared, to many, halted. But, undaunted, Chicago turned its face toward the morning of a new day — just as — one is struck by the parallel — she had done in '93. She invited the world to observe with her the victories of a glorious past and the promise of a more glorious future. Justification enough, you might agree, for Chicago to jubilate over her own birthday, so peculiarly eloquent of progress. But why the nations? A great conflict had blazed, and much of the world was ravaged and much still is lame with the wounds of war. It might have seemed, then, that progress had turned back, its lights dimmed, and the world, wallowing in the welter of the war's aftermath, in no mood for jubilee. A Century of Progress intends to bring assurance that the steady march of progress has not, however, swerved aside, nor even been seriously retarded, that so-called "recessions" are temporary, like the cloud that, for the moment, obscures the sun. History holds the evidence that this is true. Lishts Ahead It is recalled as singularly significant that, in 1893, when Chicago invited the world to celebrate the landing of Columbus on the beach of a little island in the Bahamas 400 years before, there was financial panic and widespread unemployment. Since then, the world has known prosperity such as it never before imagined. Chicago herself, at the time of that World's Fair, was still recover- ing from a great disaster. In 1871 consuming fire had sw^ept the city rendering 100,000 people homeless, destroying one hundred and ninety millions of dollars in property, and taking the toll of 200 lives. But then, rebuilt, she welcomed the world with a manifestation of her faith in the future. And the world came, to discover that the forces that spring from men's minds could not be checked for long, if checked at all. These are minds that are no more dismayed by a pause for readjustments than is the motorist who may halt beside the road to adjust his engine's carburetor. He does not believe his car irreparably ruined because of a minor flaw. He readjusts and goes on. And thus do the forces of progress sweep on. They are the forces of science, linked with the forces of industry. [10] As two pai of science anf century.

But when the plans were in the making for the exposition of 1933, the thought came that Chicago's Centennial celebration should be used to help the American people to understand themselves, and to make clear to the coming generation the forces which have built this nation. One night, President Rufus C. Dawes sat at dinner with the late Michael Idvosky Pupin, noted American scientist and inventor, and he [11] express the il forces, and nces of man- orn the theme ^ress, and its bits that dis- the funda- :overies, and :h they were ia\e been ap- .leeds of men, proceeded to an appeal to h Council at a plan of ex- story of the i in its en- and with a that would >orbingly in- The Coun- 'isory com- ion of over oremost sci- "n who gave 1 thought to ; an exhibit ubordinated :)n of actual 's that they ibly devoid e sequence, jn of a new the funda- id spending •y, biology, ible.

You see man's march upward to the present day, where, in a home of 1933, he uses and enjoys all the multi- tudinous benefits with which science and industry have endowed him. ri2i Coins Back a Century Before you enter the Fair, it may serve to prepare your mind to keener appreciation of what our progress has been, if you simply shut your eyes and imagine yourself, for a moment, transported back a hundred years. Now you are traveling as man had traveled before you for thousands of years, in a vehicle dragged by animals, for — in 1833 — it has been only three years since America's first locomotive, prophetically named "Best Friend," chugged out of Charleston, S. C, over a few miles of track to Hamburg in the same state. So the "steam cars" are as yet only a fearsome experiment. You live roughly, in your own tiny, lonely world, hedged in by forest or houseless prairies or towering mountains. Xo means of quick communication have been contrived to overcome natural barriers or to break, for months at a time, the solitude. You wear crude dress, ill fashioned, for it is still the era when clothing chiefly is made by the women of the household — it is 13 years before the invention of the sewing machine that permitted the making of clothes in volume. You eat foods that must be indigenous to the territory in which you live, for the preservation and protection of foods has not yet been developed. You read slowly and perhaps painfully by tallow candle light, for electricity has not come to work its wonders, even the kerosene lamp is in the future. You fall ill, and primitive remedies are administered, or the crude knowledge of a restricted man of medicine is sought. You live in fear and danger of epidemics which sweep the community unchecked time and time again and take their deadly toll. Xot even antiseptics for combating infection have come, and will not until 1867. Life is cruel and harsh. The Hall of Science at Night [ 13] Returning to the Present Come back to 1933. You hurtle through the air over mountains and plains on motored wings, or speed along the ground in luxurious trains, or over smooth highways in motor-powered cars. You live in a home made of materials created by the genius of man anticipat- ing the vanishing of forests. Electricity is your servant to give you light and do your work. You whisper and your words wing their way across the seas to be heard by listening ears. You read of an event happening a few hours before, thousands of miles away, and you see it pictured in the same newspaper. You dine on foods in their original freshness and flavor, but grown leagues distant, and choose your foods by the scales and charts of science for health and strength, and eat it in safety because science has protected it. You choose clothing of infinite variety of fabrics and patterns. You sit and watch the living likenesses of actors move about in their previously-enacted roles and you hear them speak. You turn a dial and take music and speeches from out of the air. You may fall ill, and medical science performs miracles with the new knowledge and new devices and instruments. Life in a hundred years, in all its phases and in multitudinous ways is more felicitous, and health safer a thousand times, than it ever has been since the world began. The Future Thus you conjure up the intimate picture, that with most of us has become so commonplace, of what science and industry have done for us in the common, everyday activities of life. And perhaps are moved to ask, "What does the future hold?" Let's go back only 40 years, when Chicago's other World's Fair was held. That Fair, historians say, awoke a nation of 65,000,000 people from a lethargic material-mindedness and turned its thought eagerly to cultural and spiritual striving. Its beautiful buildings were on classical lines. Within one ornate structure crowds milled and marveled, and whispered in awe. It contained exhibits that to some were a prophecy beyond the mind's conception; to others, perhaps, merely an amazing new kind of "trick" of doubtful value or practical promise. "The Fair," wrote an observer, "considered as an electrical exposi- tion only, would be well worth the attention of the world." An elec- trical engineer is quoted as saying, "You have everything here that was undreamed of 25 years ago. You have here the culmination of inven- tion and science. You see here the acme of modern progress. It is worthwhile to note this carefully, because if we should have another e.xhibit twenty-five years from now, the probability is that not one of the things which seem so wonderful, will then be valued. They will have been superseded by inventions so much more useful, that it is barely within the compass of any man's mind to conceive of what the future has in store for us." ri4] Almost at Once It Happened In less than three years thereafter three great discoveries were given to the world that completely revolutionized the whole of science! These discoveries served to change the atomic theory with which men of science had been groping their way. They set science on the road that it travels today. Two years after the World's Fair, Wilhelm Konrad Roentgen in Germany discovered X-Rays. A year later Antoine Henry Becquerel in France found the radioactivity of uranium, and paved the way for the discovery of radium. The next year, Joseph John Thompson in England discovered electrons by studying the nature of rays produced by electrical discharges in vacuum tubes. So familiar to us all are the commoner uses of the X-Ray, and of radium, and of the vacuum tube used in our radios, that it requires no scientific or technical knowledge to instantly grasp the applied impor- tance of those discoveries. But in theoretical science — in the laboratory of the research worker — the implications of these discoveries were epoch-making. Since they were made, science has gone faster along the road toward the steady conquest of the invisible forces that rule the universe. It has succeeded in putting many new and basic devices into harness for mankind. So fast has been that progress, in fact, that today, as you look upon the wonders of science, you wonder whether tomorrow may not hold achievements that will again completely revolutionize our methods of living. You will see also at the fair countless exhibits showing where science spans the gap between laboratory and factory. Among the dynamic displays, for example, you will observe the complete process of obtain- ing gasoline, its distillation, cracking, refining. At the same time you will see the results of the latest research into cosmic rays that may prove — science itself will not say with certainty — the source of new power that can be taken from space. You will see, too, how sound is carried on a beam of light. Will this, in the near future, become a new means of communication? You can be the judge. [15 1 Returning to the Present Come back to 1933.

[15] A Brief History Of A Century of Progress The idea of a giant celebration by Chicago on its centennial was urgently supported by Myron E. Adams before Mayor William E. Dever, who on August 17, 1923, having been duly authorized by the City Council, appointed a committee of citizens to lay the foundations for the celebration. The chairman of this committee was Edwin N. Hurley, who gathered much valuable information, considered various plans, and had prepared a report of the greatest value to its successors. Upon the election of William Hale Thompson, Mr. Hurley, on behalf of this committee submitted this report of its activities and recommen- dations, and at the same time submitted the resignations of the com- mittee's members. These resignations were accepted and the matter was, for the time being, dropped. Late in 1927, a small group of citizens headed by Charles S. Peterson, then City Treasurer, urged upon Mayor Thompson the reconsideration of the project, submitting to him convincing evidence of a great popular interest and support. Accordingly, after appropriate action by the City Council, Mayor Thompson called a public meeting of citizens to consider the proposal of having an international exposition to celebrate Chicago's hundredth birthday. At this meeting held December 13,1927, it was determined that the exposition should be announced and a corporation, not for profit, organ- ized for the purpose of preparing for it. The first officers of this asso- ciation to be elected were: President, Rufus C. Dawes; Vice-President, Charles S. Peterson; Secretary, D. H. Burnham; Treasurer, George Woodruff; Comptroller, Arthur Andersen. Things started to hum. Here was a job that called for men and women of vision, of civic spirit, of self-sacrificing mold, and the field must be canvassed and the workers chosen. The list of those men and women who have given so freely of their time, loyalty, and resources, has increased in number as the Exposition grew, while the project itself has been singularly free from inharmonious bickerings within and popular attacks from without. The Fair Gets Under Way On the fifth day of January, 1928, A Century of Progress was organized as an Illinois corporation, not for pecuniary profit, having as its charter purpose, "the holding of a World's Fair in Chicago in the year 1933." The original name of the corporation, "Chicago Second [16] Avenue oF Flags I 17 I World's Fair Centennial Celebration," was changed only July 9, 1929, to "A Century of Progress." No profit can, under any circumstances, accrue to members of the World's Fair Association. If any funds remain after payment of the outstanding bonds, they are to be given to existing organizations whose spirit and work is consonant with the basic theme of A Century of Progress. The international character of the Exposition is indicated by the fact that on February 5, 1929, a joint resolution of Congress was approved authorizing the President, on assurance that five million dol- lars had been raised by the Corporation, to invite the nations of the world to participate in the Exposition. This assurance having been given to the President the invitation was sent through our diplomatic officers to all nations on January 10, 1930. An enabling act of the Illinois legislature permitted the Exposition to be held on new-made state park land lying along Lake Michigan, opposite the heart of the city. In carrying out the aims of this Act, A Century of Progress has had the continuous and unwavering support of the South Park Commission, under whose jurisdiction this land lies. The Commissioners are Edward J. Kelly, Chairman, now Mayor of Chicago; Benjamin F. Lindheimer, Michael L. Igoe and Philip S. Graver. Without Cost to the Taxpayer In financing — as in creating, as in color, as in architecture — A Cen- tury of Progress has planned boldly, executed audaciously and looked always into the future. That is the theme of the Fair — achievement , and its promise. It breathes of the spirit which has made Chicago, and which summons the World to partake of new hope and encouragement. Here in the making, through years of financial crisis, was a several million dollar public enterprise going forward steadily, step by step, along lines not experienced in the history of our national expositions. In these days when articulate protest of peoples of the world has risen against further taxation, A Century of Progress was completed without one cent of taxation being imposed upon an already heavily burdened citizenry. No Federal government, state, county or city subsidy was asked for, or received. Other world expositions have greatly depended upon subsidies. Such moneys have constituted the major part of their funds. The World's Fair in Chicago in 1893 received $5,000,000 from the City of Chicago, $2,446,680.43 from the Federal government. The Louisiana Purchase Exposition in St. Louis in 1904 received $5,000,000 from the City of St. Louis and $5,000,000 from the Federal government, and a loan from the Federal government of $4,600,000. The Panama Pacific Exposition, held in San Francisco in 1915, received from the City of San Francisco the sum of $5,000,000, from the State of California, $4,900,000, and from various counties of the state $556,341. The Federal government did not, however, contribute. [18] Ms^^sm Lenox R. Lohr, General Manager, A Century of Progress Early needs were met from the fees of founder and sustaining mem- bers of the corporation — $1,000 each for the former and $50.00 each for the latter. The citizens of Chicago, as an expression of their faith in the enter- prise, formed the World's Fair Legion. More than a hundred thousand paid the $5.00 member- ship fee, the total of which was set aside with a trustee for return to the members if the Fair never opened or to purchase them admis- sion tickets when it opened. The basis of financing was an issue of gold notes of ten million dollars. These notes are secured Ly the deposit of forty per cent of the gate receipts in the hands of the trustees and are guaranteed by the endorsement of prominent citi- zens of Chicago. In a short cam- paign of three days, while on a flying visit to America from his duties as United States Ambassa- dor to the Court of St. James, General C. G. Dawes secured these guarantees of over $12,000,000, thus enabling the gold note issue to be made. More than fifty per cent of these notes were sold to the guarantors themselves during the summer of 1929 and in spite of the depression that followed the subscriptions that were made at that time were practically all faithfully performed during 1930 and 1931. Subsequently corporations and individuals have taken these notes in payment for services and materials and no sales of these gold notes have been made for any sum at less than par. Plans were made, the Fair started. No contract v.^as let unless there were means with which to pay for it. Yet work never ceased, more buildings were erected, more exhibits were installed, more features con- trived to make A Century of Progress a gorgeous, living spectacle that its participants will remember to their dying days, than were contained in the original schedule. No buildings were erected on any general theory that, "maybe and perhaps," exhibits would be found that, in rental for space, would pay for them. Fair officials determined that insofar as the Exposition v.as an expression of Chicago's pride and energy, just that far the citizens themselves should prepare and set the stage; that insofar as the cele- bration met the needs of industry, just so far would industry present the drama. [19 1 The Symbol of Arcturus Perhaps nothing so graphically symbolizes the swiftness with which science has moved, or presents so clear-cut a picture, as the way that the World's Fair of 1893 was opened, compared with the opening of A Century of Progress. In '93, men marveled that President Grover Cleveland could press a button and start a fountain flowing, and wheels turning as the official Fair opening. At that moment, 40 years ago, the orange star Arcturus, commonly called Job's star, blinked down upon the Fair. Light that left it then has since been racing at a speed of 186,284 miles a second earthward. The idea was conceived of opening A Century of Progress with the rays of Arcturus. A simple matter now for science to catch this feeble beam when it arrived on earth, and as it struck the great telescope of Yerkes Observatory in Wisconsin, transform it into electric energy by means of a photoelectric cell, amplify it by the methods of radio and speed it on to Chicago to start the big show's night life. A miracle, they would have said a hundred or even forty years ago. But today, the "electric eye," relays, vacuum tubes, amplifiers, micro- phones, which respond to the tiniest fluxes of energy, help to do the work of the world in almost routine manner. Progress! And as you roam the vast buildings, ride through the grounds, visit the places where fun is supreme, you will find that all within this great World's Fair is a definite part, a paragraph or chapter in the story of progress and advancement. In Speech of Color Bold splashes of color seem almost articulate with the spirit of car- nival, a flaming expression of fun and frivolity which, after all is said and done, is of the very essence of a Fair. Joseph Urban, famous architect and stage designer, sought to achieve a harmony of color on building exteriors that might also e.xpress the Exposition's deeper, more lasting implications and purposes. He has used on the buildings 24 colors — one green, two blue greens, six blues, two yellows, three reds, four oranges, two greys, white, black, silver, and gold. And it is inter- esting to note the percentages of colors used. Approximately twenty per cent of all the painted surfaces is in white, twenty per cent in blue, twenty per cent in oranges, fifteen per cent in black, and the remaining twenty-five per cent is divided among the yellows, red, greys, and green. In terms of laboratory experiment, the result .sought was a correla- tion of many buildings that are different in character, shape and mass, and which are arranged on a very informal plan. Too, the achievement [20] •;■ ^-^i'f^i^^t^ ^^-\m ^ J^'^^J^^ ^ i^\\ ?-3lK«>^ Throngs Fill the Court of Honor, Hall of Science 121 1 The North Entrance to the Hall of Science of brightness and life for materials that of themselves are not beautiful. Were one to pose as a prophet, he might well say that here is sugges- tion of a future American color harmony, distinctive, bold, that could change neutral sections of cities and towns, bring cheer and liveliness to workers in factories, perhaps revolutionize in time the conception of color effects in homes. At any rate, here, color is decorative in a prac- tical way, a planned conception to fit the architectural scheme of utilitarian modernity, and to play a part in a joyous festival. In Style of Buildinss Consider the architecture of the buildings. Wonder, perhaps, that in most of them there are no windows. Note curiously that these i'tructures are for the most part unbroken planes and surfaces of asbestos and gypsum board and plywoods and other such materials on light steel frames, rather than a parade of sculptured ornamentation. "It would be incongruous to house exhibits showing man's progress in the past century in a Greek temple of the age of Pericles, or a Roman villa of the time of Hadrian," said members of the architectural com- mission of the Exposition, all of whom are graduates of the ficole de Beaux Arts, home of the classical school. "We are trying to show the world not what has happened in the past, because that has already been effectively done, but what is being done in the present, and what may happen in the future." Modern Planning A Century of Progress considered two things in planning the types of building construction you see here. First, here was a city to be built staunchly for 150 days of life, not for the 30 years that is the anticipated life of a modern building. Why, then, build for three decades, which would be in direct contradiction to the new science of I 22 ] business that decries waste and extravagance, when the genius of man has provided factory-made parts, wall materials pre-fabricated in shops, steel frames and clips and screws for quick assenibl}-, and new composi- tions, all to permit the building of staunch structures, which yet can be quickly razed, and the materials salvaged? And why, architects now ask themselves, should Greek pillars be used when they no longer are needed, as the Greeks used them, to be actual supports, or fanciful ornamentations or projections be clapped onto surfaces when the prac- tical reasons which caused their use originally no longer exist? Second, in construction as well as in architecture, it was intended that here should be a huge experimental laboratory, in which home builders and manufacturers can study, and from which they might borrow for their buildings of the future. Windowless, these buildings assure, by virtue of the advancement in the science of interior lighting, that on no day of the Fair, no matter how dark and gloomy, can visitors be deprived of the full measure of beauty in interiors and exhibits. At the same time, they may point the way for many new departures in economical construction. They exemplify, too, the ad- vancement which has been made in healthful, controlled, filtered venti- lation. Architects and exhibitors have constant control over both light and ventilation regardless of the kind or time of day. The Fair's First Experiment The Administration building, headquarters of the Exposition, can be said to strike the keynote of the entire architectural plan. Ultra- modern in design, it was here that far-reaching experiments were made in unusual lighting and color effects, and in choice of construction plans and materials. The Administration building stands to the left after you enter the North Entrance, an E-shaped structure clothed in ultra-marine blue, Administration Buildins — East Front 123 1 [24] and yellow, with an entrance of silver, and it occupies an area of 67.000 square feet. The architects were Holabird & Root, and Hubert Burn- ham, and Edward H. Bennett. Stand before it, and two heroic figures symbolizing the theme of the Fair — science and industry — greet your e\^es, dominating the entrance. These figures were modeled in plaster by Alvin Meyer. Science is symbolized by the wheel of the zodiac at its base, and industry, by wheels and gears. Enter the main entrance hall. Here is a vast room, containing the world's largest photo-mural, a view of the Exposition. A broad door opposite the entrance gives access to a corridor con- necting the wings of the building and a wide stairway leading up to the foyer of the trustee's room. The trustee's room is famous for its modern simplicity. A high window at one end of the room commands a view of the Lagoon. Northerly island and Lake Michigan. Doors open out onto balconies on three sides of the room. On each side of a wide purple band, the ceiling and the walls are covered with fiexwood, a veneer made from Australian lacewood mounted on cloth and applied like wall paper. The mural decorations are of imported inlaid veneers in the original colors of the various woods used. A long, wedge-shaped table, unique and utilitarian, occupies the center of the room. Its tapering design enables each guest easily to see all others at the table. The portions of the E-shaped building devoted to offices and work- rooms are arranged for the most efficient utilization of light and venti- lation. The building is an experiment indicating possible trends in office and factory construction. Its low cost per cubic foot, the high salvage value of its materials, and its easy adaptation to everyday work, offer- ing an army of employees few steps to climb with no need for elevators, and giving the various offices convenient access to one another, suggest many possibilities for similar structures in the future. The roof insula- tion is of processed cornstalks. Asbestos cement board covers the out- side walls. The inner sheathing is of plaster board. Into the two and three-quarter-inch space between the outer and inner walls, an insulating material of asphalt and wood was shot by pneumatic guns. The insula- tion provided by these materials is said to be equal to a 13-inch brick wall. These materials lend themselves to mass production, therefore, greater economy, and this, together with the ease of construction cut usual building costs to less than half I In Marvels of Lishtins Should you gasp with amazement as, with the coming of night, millions of lights flash skyward a symphony of illumination, reflect again that it is progress speaking with exultant voice of up-to-the-second advancement. Xobody knows how many thousands of years ago, this spot that now blazes with light, was a part of vast stretches of ice. Glaciers [25] moved sluggishly against the cold sky, and sun and moon and stars were the only illumination. Centuries rolled by and man discovered f:re and used it to warm his wigwams, caves, and huts. Oils from animals came into use for lighting, then came kerosene; today we have electricity. And science has achieved a brilliance and skill of electric lighting which, as exemplified in the buildings of the Fair, render windows and skylights no longer a necessity in buildings; athletic fields can at night be made as bright as day for all manner of sports; and industries profit by billions through speeded-up production, and in safety, and savings in materials that once were spoiled because of insufficient light to permit workers to see clearly. In schools and homes and factories and offices advances in methods of lighting protect and preserve the human sight, and light hygiene, ray therapy and food irradiation bring renewed health and vigor to people everywhere. The Miracle oF Light A Century of Progress portrays vividly the story of Light in manifold ways. World science waits breathlessly the third exploration of the Administration Building by Night and by Day [26] stratosphere by Professor Auguste Piccard and his brother Jean. They will soar 10 miles or more above Soldier Field in an aluminum ball sim- ilar to one on display in the Hall of Science. Who knows that they will not capture some cosmic rays which will further advance the knowledge of men. They believe it possible. Crowds can study, with Professor William Beebe, whose bathysphere is on display, and in which he de- scended 2,200 feet into the sea, the light that illumines the myriad life of ocean beds. They can study infra-red, ultra-violet and various other energy rays, and perhaps catch that sense of eager expect- ancy with which Science waits, likely upon the threshold of a new era of miracles. It is with like feeling that illu- minating engineers say they look forward to illuminant development following this Exposition. "Expo- sitions always have been mile- stones in lighting progress." The Hall of Science Tower by Night The chairman of the committee of Westinghouse and General Elec- tric, engineers that designed a part of the lighting plans of the Fair, says: "The Exposition of 1933 not only will recall the advances during the last 100 years, but will give us glimpses of new developments and refinements that will be common- place in a few years." \\'ithin the buildings are bor- rowings from the future in inverted lighting, shaded arrangements, color effects, and without, a fair}'- land of lighting effect on greater scale and in more numerous ar- rangements than the world has ever seen. Back in 1893, the World Fair was illuminated with 93,000 incandescent lights, supplemented by 5,000 arc lights, in horse power representing three times the total electric horse power then used in the entire city of Chicago. Many thou- sands of visitors had never seen an incandescent light. The incandescent bulb then was faint in glow, and men knew little how to use it, yet varied [27] The Hall of Science Tower by Day arrangements and effects were achieved that caused comment through- out the civilized world, and are credited with having been responsible for immediately beginning an era of illuminating progress. Two years after the Fair, the study of light and its practical application was placed on a scientific basis, instruments were designed to measure the intensity, quality and distribution of the light flux, and the physical characteristics of the light sources themselves for the first time studied. Today, A Century of Progress is lighted also by incandescent bulbs, 15,000 of them for exterior illumination, and it is not even possible to guess the number within the Exposition buildings and concessions. They range from 10-watt to 3,000-watt power, creating a brilliancy of light that, compared with what was possible in '93 is as the sun to A Century of Progress at Night (From painting by Walter E. Olsen) f28 1 morning's twilight. Arc lights, too, are used, vastly improved over those of 40 years ago. One battery of arc lights alone, 24 powerful search lights at the South end of the Fair grounds, has a light output of 1,920.000,000 candle power! It is anticipated that the total current consumption for the period of the Fair will reach 18 million kilowatt-hours. Scientifically controlled clear light predominates for the outdoor lighting, its effect on the brilliant color of the buildings achieving its beauty, while colored lighting is used for special displays, fountains and simulations of cascading water falls, or brilliant skies at sunset, or varied interesting patterns that illuminating science now finds possible and profusely indoors. Colored Lisht in Tubes A new kind of illumination has come, and in the Century of Progress it is used in greater profusion than ever the world has seen. When President Dawes of the Exposition threw the switch on June 12, 1932, that first lighted the Hall of Science, the largest amount of gaseous tubes ever used on any one surface sprang to life. As you mingle with the throngs at night, you stand in the greatest flood of colored light that any equal area, or any city of the world has ever produced. This color lighting is that of rare-gas tubes. You see it in blue, green, and yellow in countless signs and on billboards in letters and varied designs on your streets at home, in cities and towns and villages. This new light is produced by introducing rare-gas into a tube from which the air has been pumped, and the tube sealed, then a current of high-voltage electricity is passed through. The color radiated from the tube is determined by the element the tube contains and by the color of the tube; the red by neon in clear tube, the blue by mercury in a clear tube, yellow- by helium in a yellow tube, and green by mercury in a yellow tube. True to the Fair's purpose of presenting achievements, and showing their how, you can go to the Electric Building and watch these gaseous tubes being charged, and bent into the shapes required. From fireless night to the greatest display of light humans have eve seen is the span of progress A Century of Progress depicts for its visitors and men who remember the feeble light of the coal oil lamp, or who have sat beside the flickering candle flame, may gaze and exclaim that here is illumination at its apex. But science marches on. Here, per- haps, is only a hint of what the future may produce. [29] The Basic Sciences We shall suppose that the visitor has acquainted himself, in a gen- eral way, with the location of the park in which the Century of Progress Exposition has been built. This is a highly interesting bit of land, a space of four hundred and twenty-four acres, rescued from the lake since the Columbian Exposition of 1893. We shall suppose further that the visitor is entering the grounds at the northern gate, just east of the Field INIuseum, and that he walks south along that portion of Leif Eric- son drive which is now known as the Avenue of Flags. This brings him, in about five or ten minutes, to the Hall of Science, a beautiful struc- ture designed by Paul Cret of Philadelphia. Here are housed the exhibits which illustrate the things that men are now thinking about in the various branches of learning known as the pure sciences. Mr. Cret's problem was to build a structure which would lie directly across the Leif Ericson drive and extend down to the edge of the water in the lagoon. This problem he solved by making the northern front a graceful circular arc of high pylons extending a welcome to each approaching visitor. The rest of the building is in the shape of a U with the arms of the U extending to the water's edge and enclosing a court of three acres. The building itself covers an area of more than eight acres; something like 400,000 square feet. Two floors are used for exhibiting the basic sciences which, for con- venience of operation, are grouped under the following seven heads: mathematics, astronomy, physics, chemistry, biology, geology and medicine. The ground floor, which is on the same level with the surroimding park, is devoted to medicine and industrial applications of science. The main floor, which is approached by a gentle ramp from the north, also by a viaduct from the industrial buildings on the south, is given over entirely to the basic sciences with the exception of medicine and astronomy. Since, however, astronomy is so splendidly represented in the Adler Planetarium, under the direction of Professor Philip Fox, the main floor of the Hall of Science is devoted to the remaining six of the basic sciences. Mathematics, "Queen of the Sciences" Let us suppose that the visitor enters from the circular terrace, on the north side of the building, through the center of the pylons. He emerges into an octagonal room where he is at once confronted by an illustrated story of mathematics through the ages. The tale is told by [30] 31] means of four projection lanterns, one for each of the four great fields into which modern mathematics is divided. Turning to the right and walking west, one meets various other mathematical demonstrations which have been prepared under the direction of Captain F. H. Roberts, U.S.X., and Major C. L. Fordney, U.S.M.C., who have had charge of the section of mathematics from the beginning. The visitor here will be well repaid by an examination of the beautiful and accurate surfaces of Mr. C. E. Johansson and the exquisite models of Dr. Saul Pollock. He will here have an opportunity to see how trigonometry is used in navi- gation and how various other branches of mathematics are employed in our daily work. Celestial navigation is illustrated by an ingenious animated exhibit which will also show fundamentals of "piloting" or navigation in sight of land or lights. The velocity of light is a quantity which is of major importance. The work of Professor Michelson in determining this value is well known. In his calculations a machine called "Michelson's Harmonic Analyzer" was used. This historic mathematical instrument is on dis- play in the mathematical section. The Galton Quincunx is the imposing title given to one exhibit in which probability curves are formed by ball bearings deviated in their fall by steel pegs in "penny slot machine" fashion. Another exhibit is one in which the probability of a rod falling on any one of a group of parallel lines is used to determine experimentally the value of that oft encountered quantity given in the elementary school texts as 3.1416, the universal symbol of which is the Greek letter pi. "The Sieve of Eratosthenes" is the classical name given to a device which utilizes a beam of light and a photoelectric cell to determine the prime factors of numbers. Struggles with elementary arithmetic will be recalled with a sigh as the visitor marvels at the rapidity with which Dr. D. N. Lehmer's machine takes numbers apart. Professor Theodore Soller of Amherst College has loaned to the mathematical section his machine for the composition of Simple Har- monic Motions. The beautiful curves may be made by the visitor himself. The "heterod5me" of radio is one of the interesting curves produced. A magic square, which will print on a slip of paper a number which one has in mind, is a feature of "Mathematical Recreations." A happy family of ellipses (though their foci be apart) is another animated exhibit. The dairy farmer who has wondered, while turning the crank of his "separator," over what was going on inside the machine will be able to see centripetal force "on the job." The gyroscopic action of atoms is shown by the magnitization of an iron rod when rotated rapidly. On the main floor is a modern gyroscopic compass in operation. One "repeater" which indicates the direction given by the main "gyro" is installed on the Balcony of the Great Hall and another is in the [Z2\ mathematical booths. The "control" board with its motor generator is installed on the balcony. Exhibits showing how correct time is obtained and transmitted, loaned by the U. S. Naval Observatory, may be seen on the balcony. A companion exhibit prepared by the Xavy shows the "Developmental History of Radio Communication." One hundred and forty-one years of mathematical development from D'Alembert's equation of wave motion in 1747 to the beginning of the experimental stage by Professor Hertz is portrayed in a way understandable to the layman. The kingdom of Italy has loaned to the mathematical section a collection of original instruments used by Marconi in his early experi- ments with "wireless." The application of Bernoulli's theorem to aerodynamics is shown by models in a wind tunnel, prepared by the National Advisory Com- mittee on Aeronautics and exhibited on the Balcony of the Great Hall. The service to mankind of mathematics, its progress as this service is being performed and its fostering of an appreciation of the view^ taken by Jacobi, "the ultimate end of mathematics is the greater glory of the human mind," is the mission of the mathematical exhibits of A Century of Progress. The Story of Physics Passing toward the west, along the main aisle, one comes to the section on physics, under the direction of Dr. Gordon S. Fulcher who has presented in groups the essential phenomena of modern physics. The Great Hall of the Hall of Science The ninety exhibits are arranged in sequence on tables live feet high, enabling all to see each exhibit before going on to the next. Plow does the air in tires hold up so much weight? Why does steam exert pressure when in contact with heated water? How can electric power produce cold in refrigerators? Why are water drops round and why are crystals regular in shape? These are some of the cjuestion the exhibits on molecular physics will answer. For instance, the exhibits include a working model with steel balls instead of molecules showing how pressure is due to bombardment of the walls by molecules which have the speed of rifle bullets. An intermittent fountain, a balloon alternately expanding and collapsing under a bell jar, an engine with glass cylinders operated by electrical heat, icicles formed by evaporation, drops four inches in diameter, an umbrella shaped water film and other exhibits will be found interesting and instructive. The exhibits in the sound section will explain how sounds are produced, how sound waves travel; when resonance occurs, what deter- mines the pitch of a sound, how speech sounds differ and how talking films reproduce sounds. The visitor will see a large tuning fork apparently vibrating very slowly through a large amplitude; he will hear four tubes of different lengths singing in succession and will see at the same time the images of the vibrating flames within the tubes, reflected by a rotating mirror as flaming saw teeth; he will see a magnified image of the sound track on a movie film and at the same time hear the corresponding sound. In the final exhibit of this group, speech sounds will be transmitted on a light beam which the visitor may intercept if he wishes. The great discoveries upon which is based the astonishing develop- ment of the great electrical industry of today explain the fundamental principles of the dynamo, transformer and motor. We cannot tell why an electric current affects a magnet or why a moving magnet may induce a current in a nearby coil; but the exhibits demonstrate these effects and show how modern electrical machinery makes use of these experimentally discovered principles. By the use of lenses in telescopes and microscopes the eye is enabled on the one hand to see glories of the heavens, otherwise invisible, and on the other to study the minute structure of metals and microbes. The refraction or bending of rays of light by means of a lens is shown in an exhibit, also the way in which a lens forms an image. Another exhibit shows how eyeglasses correct defects of the lens of the eye. The beautiful colors of soap films tell us that light is a wave motion similar to radio and that the frequency of vibration of green light is higher than that of red. An exhibit shows in a simple way how we know that the wave-length of light is about twenty millionths of an inch. Other exhibits show beautiful colors produced by sending polarized light through a sugar solution or a crystal. Light from an arc and from neon tubes is analyzed into the component spectrum colors. The electric eye, or photoelectric cell, is a modern genie produced by [34] scientific research. Exhibits show the fundamental phenomenon and also applications to the reproduction of sound. Without the photo- electric cell, television would be impossible. The electron and the proton, tiniest of particles, cannot be seen individually, but when given speeds of 100 to 100,000 miles a second they are called cathode, canal, alpha, or beta rays, and produce effects which can be seen. E.xhibits show luminous effects due to cathode and canal rays in vacuum tubes, also tracks of single alpha rays from radium, and the properties of x-rays which are produced when cathode rays strike a target. Finally a "hodoscope" will show the paths of individual cosmic rays by means of flashing neon lamps. Instruments of Exploration If now, instead of going down the ramp to the floor below, one turns and enters the great room in the Hall of Science his eye is at once caught by two large exhibits on the main axis. One of these is a pair of globes. The lower of the two is the steel sphere in which William Beebe and his companion descended one-half mile below the surface of the ocean; the upper globe is the gondola in which Auguste Piccard ascended into the earth's atmosphere to a distance of more than ten miles. At the south end of the room is a collection of the building stones of which the earth is composed, that is, the ninety-three chemical elements. Their source and use will also be shown. Above this display is a 10-foot rotating terrestial globe representing our planet and showing the chief source of the common chemicals. The inscriptions on the walls of this large room are worthy of careful study by any one at all interested in any phase of science. Over ai'ainst the east wall are six pieces of apparatus, each of which sets forth A Diorama of the late Jurassic Age. Dioramas pictures in three dimensions- are used in hundreds of displays at A Century of Progress Exposition. The foreground is modeled in true perspective to blend with a painted background [35 1 a distinct and recent achievement in physical or biological science. Each deserves careful observation; for it is not every day that one has an opportunity to make the acquaintance of a gyroscopic compass or to view a model of the Bohr atom at close range. Chemistry and Its Application Along the west wall, under the balcony, is shown the science of chemistry by means of a series of exhibits which are at once funda- mental, valuable and interesting. They connect immediately with important industrial applications shown on the floor below. The three fundamental types of chemical processes are shown — chemical change by combination, by separation, and by exchange. \'arious methods of producing these chemical changes are also shown. The application of chemistry to our raw materials is forcefully demonstrated. The development of petroleum from the dirty muck to a clear, white gasoline; the transformation of rubber latex to finished rubber goods; the utilization of air for production of oxygen and rare gases; the change of the undesirable by-product coal-tar to beautiful dyes, medicinals, and plastics; the harnessing of electric power for the production of steel, acetylene, and chromium plating; and even the chemical utilization of our foods in the human body are strikingly portrayed in clear and readily understood manners. These clever demonstrations were designed mainly by Dr. Irving E. Muskat who has been in charge of the chemical section. Before leaving the great room the visitor will find it well worth while to read the fourteen quotations on the east wall, the nineteen inspiring names on the front of the balcony and the nine groups of scientific achievement inscribed on the west wall. Dynamic Exhibit Showing Thermit Reaction [36] The Science of Life The spectacular exhibit that represents the science of biology in the great central hall is a mechanical representation of a section of a bass- wood twig, seven and one-half feet in diameter. As you stand before it, you see it attain before your eyes, a year's growth in 75 seconds. The demonstration is performed by means of a series of plates and canvasses on a moving model, showing the direction and amount of growth of wood and bast. If, on leaving the great hall, the visitor strolls toward the east (which here always means toward the lake), he will find before him the whole story of modern biology presented through experimental evidence. This section has been under the guidance of Dr. J. F. W. Pearson. Moving models of the developed human being show the finished physical machine in its internal action. A life-sized model of a man explains the circulation of the blood, with a magnified heart pumping, showing the action of its valves. A simplified mechanical reproduction of the digestive system will portray the absorption of food elements by the body. The cell theory of plant and animal-life is illustrated by some exquisite drawings by Mr. Walter A. Weber; while the storage of food in the cells of a corn-plant is shown in a dynamic model which sets forth very clearly just what sunlight does for a plant. In the south wing of the Hall of Science will also be found the rare screen-pic- tures by Mr. George Roemmert in which he projects for his audience, not a series of lantern slides or films, but those minute forms of actual living animals and plants just as they would be seen by an observer looking through a micro- scope of very considerable power. Modern views of inheritance, the evidence for evolution and the physiology of the human frame are presented in a concrete way that demands careful study. The traveler will now do well to return to the north wing of the building, entering the balcony at its south stairway, observing the mathematical display and the library of one thousand volumes and then descending from the balcony by the northern stairway to the main fioor. Geolo3y and Its Services He will now find it but a few steps through the octagonal hall, where he entered, to the exhibits of the geological section which has been under the able leadership of Professor Carey Croneis of the University [37] Mechanism lor Artificial "Growing Twig" in Biology Exhibit of Chicago. Here, in the study of the earth's crust, one discovers how all the other sciences have been pressed into service to diagnose condi- tions in the interior of the earth, to locate valuable metals, to predict where petroleum will be found, to show, in brief, how all our present landscapes and geography have resulted from erosion by rivers of ice, from deposition by rivers of water, and by shearing and compressional forces still operating over large areas. The ''Clock of the Ages" The science of geology is epitomized by a giant "Clock of the Ages" which ticks off the two billion years or more of the earth's history on a conventional clock dial. Geological pictures appear on a screen in the center of the clock face, and they are described by a synchronized phonographic record. The visitor also sees operating models demon- strating the formation of mountain ranges, the growth and activities of volcanoes and the eruption of geysers. Further, he is initiated into the mysteries of earthquakes and the ingenious manner in which man has forced them to write their own records. A large group of spectacular displays of similar type, representing earth features such as the Yellow- stone Geysers, the Grand Canyon and the Carlsbad Caverns, are be'ng furnished by the National Parks Service. The romance of oil is revealed in a great sequence of operating exhibits sponsored by the American Petroleum Industries. These displays cover every phase of oil and gas production. Other exhibits explain man's modern, almost magical, methods of locating the deeply buried raw products which formed the basis for his century of progress. Science in Industry Everywhere the visitor turns — here, and throughout the Fair — he finds the application of science's discoveries in industrial benefits for humankind. For example, the visitor sees a real rubber tree brought all the way from Africa, from which the rubber latex seems to flow naturally. He sees the coagulation of rubber with formic acid, and then its electro- plating — a relatively new process carried out by combining the elec- trically neutral rubber with carbon, so that it can be deposited by an electric current on the linings of chemical receptacles, tanks, and the like. There is shown also the vulcanizing of rubber, and the nature and uses of accelerators, pigments, and anti-oxidents in the processing of various kinds of rubber. Again, industry shows the actual process by which coal tar is trans- formed by chemistry into dyes; how perfumes, and medicines, including antiseptics and anodynes, and T. N. T., and other things, are made from the 12 primary substances which coal tar contains. Thus, the visitor sees the fundamentals of science, and then sees their step-by-step progress to the finished product that contributes so much to his well-being, and comfort, and health. 1381 The Story oF Medicine Descending now to the ground floor, preferably along the easy ramp leading down from the north wing of the main floor, one finds himself in the midst of the three important branches of medical science, namely medi- cine, dentistry and pharmacology. Here, too, one finds a science which uses the best there is in each of the other sciences and then some. Dr. E. J. Carey, who has managed the collection and installa- tion of these exhibits, has depended mainly upon the various insti- tutions, such as uni- versities, clinics and scientific societies. No exhibit in the entire building has more of human interest or is more cosmopolitan in character than these rooms in the north end of the ground floor de- voted to the detection, the cure and the pre- vention of our bodily ills. At the east end of the ground floor there stands a giant man. He is six feet tall, and rises from a pedestal three and one-half feet high. He is transparent. As though you were sud- denly endowed with X-Ray eyes you may view the inside of the human body. This transparent man, composed of cellon, and brought to A Century of Progress from Dresden, Germany, is one of only two in the world, and required 18 months to make. He cost ? 10.000. He properly begins the story of the science of medicine in this theater of the sciences. [391. The Transparent Man An exhibit of the great Pasteur, sent by the Pasteur Institute from France, looms to your right, as you stand facing the Transparent Man. This exhibit, an illuminated map of the world supplemented by photo- graphs, tells the story of the life of Louis Pasteur, and some of his accomplishments. To the right, you will see an exhibit sent from Germany by the Robert Koch Institute, which displays the life and the work of the great man who discovered the tubercle bacillus in 1882, and started medical science upon its studied campaign against tuberculosis. Eyes left, and you see a remarkable exhibit of the Wellcome Research Institution from England. It tells the story of the work of Sir Henry Wellcome, American, who fought the mosquito in Africa and won, and laid the way for extermination of yellow fever. The Wellcome His- torical Exhibit, a museum in itself, shows you dioramas that illustrate epoch-making events in British medicine and surgery. Northwest of the Transparent Man, the Italian exhibits show you Italy's great pioneers of the three basic medical sciences — pathology, anatomy, and physiology — respectively, Leonardo de Vinci, Morgagni, Spallanzani. With models and apparatus they tell you something of how these men, and Galvani, and Malpighi, and Vesalius, lit the lights by which the men who came after them charted their course, for the welfare of mankind. Northeast of the Transparent Man are exhibits recording medical triumphs of research workers in the ignited States. Austria, Holland, Canada add their contributions, and you have an absorbing, yet colorful story to study, and to carry away with you for a lifetime of reflection. Thus, the Transparent Man stands as a symbol of world medicine, a common denominator of the nations. You may see in the Austrian exhibits the work of Austrian scientists, and in those of Holland the structure and function of the nervous system told in a simple, dramatic way. In the Canadian section, McGill University, through murals, transparencies, and photographs, portrays the history of James McGill, and the development of the Montreal General Hospital and its work, and of the work of Sir W'illiam Osier. It was at McGill University that the first surgical X-Ray photo- graph was taken, two months after Roentgen announced his discovery in 1895. The photograph itself is shown. You can go back to 1550 B. C. and read descriptions of more than 700 different remedies for human diseases, in the exhibits of the Amer- ican Pharmaceutical Association. You can watch the antics of an Indian medicine man, practicing his primitive medicine, in the exhibits of the Milwaukee Public Museum. Marquette University of Milwaukee shows you a history of Bright's disease, and the progress medicine has made to prevent and cure it. The .American Medical Association shows you the progress of medicine in the last 100 years — the old saddle-bag doctor who went his lonely way, measuring out his meager doses in sparsely settled sections, [40] and the physician and surgeon of today and his highly technical equip- ment. The American Society for the Control of Cancer shows you the advance science has made to frustrate the ravages of this dread disease; the Chicago Municipal Sanitarium and the Chicago Tuberculosis Insti- tute tell you of the strides that have been made to subject this disease to control, and the Cleveland Clinic Foundation shows you motion pictures illustrating the discovery of the circulation of the blood by Harvey in 1628, and of blood transfusion, and of the functions of the thyroid, suprarenal, pituitary, and other glands. It's difficult to believe that Oliver Wendell Holmes had to fight to persuade the public that doctors should exercise cleanliness in child- birth, but Harvard University tells this story in its exhibits. Dr. Crawford W. Long of Georgia first used ether in 1842, and the University of Georgia tells you the story and shows you the develop- ment of the use of anesthetics in modern surgery. The Mayo Foundation develops three themes in its extensive displays: 1. Diseases of the digestive tract; 2. The thyroid gland; 3. The sympathetic nervous system. A striking exhibit, expressive of the progress of medicine in the last century, is that of the Chicago Board of Health. In 1849 the general death rate was 73.8 per 1,000 persons, in 1932 it was 9.8. The typhoid fever death rate in 1891 was 173.8 per 100,000, today it has an amaz- ingly reduced rate of 0.4! The Chicago Medical Society and Woman's Auxiliary show you the medical history of this youth of cities. The Xew York City Cancer Committee shows you the history of the magnifi- cent fight that science has waged and is waging against this malignant disease, and the University of Illinois College of Medicine, College of Dentistry. Department of Animal Husbandry, and the Illinois Depart- ment of Public Health, give you interesting sidelights on methods of treatment and causes of hay fever, tuberculosis, pneumonia, hemophilia, and rabies. The Illinois Public Health Service shows contrasting pic- tures of methods of sanitary handling of milk today, and of insanitary methods of other days, and presents also the health conditions of 100 years ago, compared with those of today. The University of Chicago presents an inspiring display showing the giant strides that practical humanitarianism has made in reclaiming the crippled child for work and for enjoyment. Loyola University of Chicago shows the organs of the human body for easy understanding and study. The University of Wisconsin shows you the work of Beau- mont, the first American physiologist, whose experiments upon poor Alexis St. Martin, French voyageur, up in the woods of Wisconsin, in 1833, contributed so largely to the advance of medical knowledge in the treatment of digestive disorders. Exhibits in Dentistry In the large dental exposition, you will see the denture, controlled by heavy springs, with which George Washington, in his later years, [41] laboriously chewed. You may read, for a conception of the simplicity of early American dentistry, the advertisement of Paul Revere, gold- smith, i)rinter, engraver, and dentist, offering to make false teeth "that look as well as the natural, and answer the end of speaking to all intents." The development of dental science, which is typically Amer- ican, is illustrated by an exhibit of equipment of the itinerant dentist of 1833, and a fully equipped operating room of the period of 1933. U. S. Public Health Service The U. S. Public Health Service has an extensive exhibit, which contributes further to the story of medicine's progress, in the U. S. Government building on Northerly island. This exhibit, occupying 2,500 square feet of space, shows the progress made in public health and sanitation since the establishment of the service. It is presented in divisions and shows the work of the service in combating pellagra, tularemia, undulant fever, typhus fever, spotted fever and parrot's disease. The exhibits extensively demonstrate the vast efforts the government has made, and the methods used, to exterminate disease. Scientific Exhibits by Foreisn Nations The visitor who returns to the north wing on the main floor will be splendidly rewarded for time spent in the bays occupied by Italy and Denmark. Each of these countries has a wealth of fundamental discoveries to its credit; and these are here shown in a concrete and highly interesting form — for example, a section, in replica, of the ancient Roman vessel recently rescued from Lake Nemi, after two thousand years under water; and a replica of the simple compass with which Oersted made the brilliant discovery of electromagnetism. The Unity of Science A visitor who has completed a trip through the Hall of Science can hardly fail to note that amidst the variety of phenomena, apparatus, and processes here displayed there runs one common feature, namely, the method of modern science. The problems differ, the materials differ; but in every case there is clear vision as to just what the problem is; this is followed by observation and arrangement of apparatus in such a way as to compel Nature to give an answer. The Adier Planetarium In the Hall of Science, you will have seen the fundamentals of mathe- matics and physics that properly lead into the science of astronomy. Now you may cross over the Science Bridge, if you wish to finish the story of the basic sciences all at once, turn to your left, and go to the northern end of Northerly island where stands the Adler Planetarium and Astronomical Museum. This rainbow-granite building with its mushroom dome is world famous, for within it is an intricate mechanism called the Zeiss projector, [421 The Adicr Planetarium the only one in the United States, and one of only two in the world. With this instrument is staged a spectacular drama of the heavens. Once every hour, visitors are admitted to a circular room to sit beneath its domed white ceiling. The light is flashed off. The ceiling becomes a blue sky, sparkling with millions of stars seeming so close and so real that you feel that you can reach up and touch them. A lecturer tells you about this firmament. His pointer is a beam of light. Behind him is a concealed switchboard, with which he controls the apparatus. You are permitted to look ahead into the future and know where the Pole Star or any other heavenly body will be situated at a particular minute of a particular day decades or centuries hence. You can look back into the past and see the heavens as they appeared when Christ walked on earth or when Galileo studied the stars with the first telescope. Should you arrive while a lecture is in progress, you can entertain yourself by strolling about the halls or exhibit rooms downstairs. The Planetarium, which is under the direction of Prof. Philip Fo.x, formerly of Yerkes Observatory and formerly professor of astronomy at North- western University, has a wonderful collection of instruments which men of science in centuries of the past have used. Four hundred years ago the Strozzi family of Florence began a collection of scientific instru- mmmfff lr?rir*rHrHc»[lt[!|p The Field Museum of Natural History (431 ments, gathering and preserving those of worthy achievement. About 40 years ago this collection passed into the hands of Raoul Heilbronner in Paris, and after the World War to W. M. Mensing in Amsterdam, and from him to the Chicago museum. Downstairs you can push a button, and see exactly how the light from the star Arcturus could be caught by a photoelectric cell on arrival from its 40-year journey to earth. You see a model of the rotating prisms with which the late Albert Michelson of the University of Chicago showed the velocity of light. The Field Museum of Natural History At the front door of A Century of Progress, directly west of the north entrance to the Exposition, stands one of the world's greatest scientific museums, the classically beautiful Field Museum of Natural History, containing contemporary and ancient exhibits from all parts of the globe, including the finds of many distinguished explorers. The John G. Shedd Aquarium Chicago has the largest and fmest aquarium in the world in the John G. Shedd Aquarium, which is located near the north entrance of the Exposition. Specimens from oceans, rivers, and lakes are displayed amid dramatic surroundings which counterfeit the natural settings in which the lish are found. The Terrazzo Esplanade As you leave the Planetarium, you may stand on the steps and look westward down upon the Terrazzo Mosaic Esplanade, the gift of the National Terrazzo Association, which will remain as a permanent approach to this building that is visited by multitudes yearly. The esplanade begins at the east end of the Twelfth Street bridge, which connects Northerly island with the mainland at this end of the grounds, and is sloped upward toward the Planetarium, so that you may look down upon the beautiful mosaic patterns that lie in the bottom of shallow pools — twelve of them, each representing a month of the year. ..ri^ Til «H ««":,» .......I... John G. Shedd Aquarium [44] From Wagons to Wings It has been only sixty- four years since two sweating gangs of labor- ers met near Ogden, Utah, May 10, 1869, in a thrilling race from east and west, and drove the golden spike that completed the span of the continent with iron bands. At that time there were less than 40,000 miles of railroad in this country. Small, slow engines yanked crude cars from coast to coast, but the nation could hail them as wonderful monsters of progress. Crowds came in rattly buggies to watch the trains go by, or gratefully hauled produce to sidings in horse-drawn wagons, a market found at last, and the "Iron Horse" pounded out the beginnings of communities. cities, a wider civilization. For the first time, the west, and east, and north, and south were welded together, as one great country. Thirty-five years later, the horseless carriage chugged its way into our existence. And now the cities and towns and farms were welded even closer, this time by speed and convenience that made it possible for farmers to get to towns and to cities, in little time, and residents of cities and towns and the farms to go places whenever the whim seized them. Came then the airplane to laugh at miles, and make it possible to cross the continent from sun to sun. In less than the Biblical allotment of the years of a man's life, these The Breathing Dome of the Travel and Transport Building [45] modes of transportation have played a mighty part not only to permit the growth of a nation, but profoundly to affect its industrial, its political, its economical, even its spiritual life. A Colorful Pageant Just south of Thirty-first street, on the lake side, you may watch the dramatization of this century of progress in transportation, the pioneer in the field of communication. On a triple stage, in an outdoor theater, two hundred actors, seventy horses, seven trail wagons, ten trains, and the largest collection of his- torical vehicles ever to be used, operating under their own power, pre- sent "Wings of a Century." Here is the "Baltimore Clipper," the fastest boat of them all, from 1825 to 1850— the "Tom Thumb," first locomotive of the B. & O. — the De Witt Clinton, from the old Mohawk & Hudson (New York Central) — the Thomas Jefferson (1836) of the Winchester & Potomac (first railroad in Virginia) — then the old "Pio- neer," the Northern Pacific engine of 1851 — a giant locomotive of today — then the Wright brothers' first airplane. There is a one horse chaise, like George Washington traveled in, and covered wagons and stage coaches of gold rush days. In a comfortable grandstand, with Lake Michigan for the backdrop, you may review the battles wath Indians, frontier fights, the hardships of the pioneers, thrilling, epic moments in the history of the winning of the west which tell the story of how the waterways and the railways pushed the frontiers ever westward, building a nation. When you have viewed this panorama of transportation, you will want to cross Leif Eriksen drive to the Travel and Transport building Part of the Travel and Transport Building [46] Detail Travel and Transport Building designed by John A. Holabird, Edward H. Bennett and Hubert Burn- ham, and enter its dome. For the first time in architectural history a dome has been constructed on the principle of a suspension bridge. Just as a suspension bridge has no pillars, columns, or arches to support it from below but de- pends on cables to carry its load, so the dome of the Travel and Transport building is suspended 125 feet above, the ground by cables attached to twelve steel towers. The reason for the daring use of this suspension principle was the necessity for a clear, unob- structed space for exhibits. The result is a demonstration of how the desired result may be satisfac- torily achieved at a much lower cost per cubic foot and we have a dome with an interior diameter of 310 feet at the base, and 206 feet clear of any obstruction. This dome is made with joints that allow for expansion and contraction as the temperature varies, resulting in a variation in circumference of more than six feet. The roof rises or sinks as much as eighteen inches, depending on the amount of snow or atmospheric pressure on the roof. This has given rise to the name, "the dome that breathes." When your attention is turned to the exhibits themselves the first thing to greet your eyes is a mammoth crown, surmounting a pillar, from which four projection machines throw motion pictures upon a ring of screens, 30 feet high, around the walls. This 630 feet of screen forms the stage for the story, in filmed detail, of the essential contributions of oil to the powering and lubricating of transportation. You may wish to pause and see "Old Number 9," the first sleeping car ever built, a little wooden car with open platforms and crude berths, that looks a bit humble as it stands between two great modern Pullmans, all of aluminum, and stream-lined, which are the last word in sleeping car construction for 1933. But little No. 9 can be proud of its history. First to be built,* it made its initial run from Bloomin'j;ton. Illinois, to Chicago in 1858. And later it was a part of the train that bore the body of Lincoln to Springfield for its final rest. And here's an old stage coach, scarred by bullets and Indian arrows, a Rocky Mountain stage coach that could tell many a tale of bandits and redskin raids. Nearby, an original Conestoga emigrant wagon, in which pioneering families slowly moved toward new and ever new horizons, braving death and hunger and suffering. [47] And here is a horse and buggy. Nearby one of the old buggy-type automobiles, first of its breed, startling contrast to its modern lineage, to be seen further on in the exhibits. An original Curtiss box-kite pusher is shown, an early type of plane, far cry in design and power, but not in years, from the monster planes that are shown later on. Another relic of the early days is the historic John Bull engine and train, a most amusing exhibit, which was shown at Chicago's World's Fair of 1893 in those days operating under its own power. Dioramas that Talk Passing into the rectangular section of the building you see a different diorama from any you may have seen heretofore, for its figures move, and speak. It is utilized to reproduce the scene of the laying of the corner stone which marked the birth of the railroad system. Quaint figures, in beaver hats, stocks, ruffled shirts and flaring pantaloons, faithful reproductions of the fashions of the day, carry on conversation, make speeches about this amazing event. A depressed, illuminated map of a section of the globe shows by flowing lines of light the national and international trade routes served by a single railroad system, while paintings tell the story of transporta- tion in the development of civilization. Near the southern entrance of the building Is the giant electric locomotive of the world. When you have walked through its cab, and examined the intricacies of its machinery, you may turn to the cherished old "Pioneer," first locomotive ever to run out of Chicago. Just the length of the tender. It stands on a piece of old style, light-weight track in front of a huge painting of its modern successor. You will be interested also in the displays of the varied types of road- beds, specimens of ties, and track ballast, that indicate provisions made for safety and comfort in traveling. Have you ever rolled smoothly into a great city at night, myriad lights making a maze of miles of track? And wondered how in the world trains could enter and leave, all on schedule, without confusion? Talking pictures in color tell you that story of the inside working of railroad operation. The great Southwest is a land of romance, and a series of elaborate dioramas show the progress of this vast section of the country in the past 100 years. The dioramas tell the tale of cotton, livestock, wheat and oil. Young, dynamic, bustling cities of this section are shown with other dioramas. A map of Glacier National park is alive with miniature trains in operation. And a Story of the Old Rough Days Pony express riders once spurred their mounts across the plains, braving dangers of bandits and Indians, and writing a colorful history. Seven paintings depict this story. On tracks, under roof, are a glass-lined, steel refrigerated milk tank [48] car, built for speed to rush milk iresh and sweet to modern homes, far cry from the old horse-drawn milk, wagon, and tin milk cans. Also are exhibited a model refrigerated meat car and a dry-flow tank car for products such as cement and soda ash. The Automobile Link A "glass automobile'' makes a striking exhibit, showing through nine panels of glass the parts of the machine in action while an electric fountain illuminates them with colors. The Age of Aviation A great illuminated map tells one in swift summation the amazing growth of aviation since its comparatively recent birth, showing a lighted network of airways serving forty-four states, and dramatically exhibiting the night flying operations. The map illustrates the increase in travel by air since 1926, when 4,600,000 miles were flown, to 1932, when 50,000,000 miles were flown, 40 per cent of which was night flying. This map and other exhibits of flying service are sponsored by the air mail-passenger operators of the United States. Different types of plane, both for domestic and foreign service, are on display. The Aid of Oil In the Great Hall is shown a complete oil well derrick, demonstrating the underground work, a rotary bit biting down through the layers of rock and sand. The chassis of an automobile is cut away to show motor car lubrication, and a spectacular clanging of gongs, and shrill of sirens, and whirling wheels of a fire engine add life to this section of the exhibit space. Striking Exhibits in Outdoor Area South of the Travel and Transport building, is an outdoor area for exhibits. You can see one of the fastest and most luxurious trains in all of Europe, the "Royal Scot," crack train of the London, Midland and Scottish railway. This train makes the run from London to Edinburgh in eight hours regularly. On one side of the "Royal Scot" stands a gigantic Chicago, Burling- ton and Quincy locomotive at the head of a V. S. Railway Postoffice car. chair car, diner, two sleepers and solarium lounge car. [49] The "Royal Scot' Dining Salon — Private Train of the President of Mexico On the other side of the British train are the air conditioned cars of the Baltimore and Ohio Capitol Limited, representing the eastern roads of the United States. On the next track are the palatial special coaches of the Presidential train of the Republic of Mexico, which are considered by many to be the most luxuriously furnished cars in the world. On display in one of the cars of this train is a priceless collection of jewels, the famous Monte Alban gems. These gems have been traced back, to early lapidaries of the ancient Mexican civilization. They comprise ornaments of jade, jet, ivory, amber, bone, and the like, set in gold, recently recovered from ruins and rubble. One of the largest freight locomotives in the world is shown by the Delaware and Hudson railroad. A demonstration of mine rescue equipment and its use is shown nearby, in a U. S. Bureau of Mines rescue car, and General Steel Cast- ings company show a new type gondola car of unique construction. A Tractor Run by Radio A farm tractor crawls about a two-acre field, controlled in its maneuvering solely by radio, from a switchboard at the edge of the iield. This is the exhibit of the International Harvester company, which also shows operation of cultivating and harvesting machinery on simulated crops. Demonstrations of trench and ditching machinery are given on the demonstration field by the Barber-Greene com.pany. [50] A Glass Tower Parking Place A glass tower of the Xash Motors is a spectacular feature of the outdoor exhibit. This parking tower, built by the Whiting corporation,, cooperating with Nash Motors, is eighty feet tall, and it carries sixteen cars, each car in a pocket, its full height. Colored lights bathe the tower, and Xash cars pass up and down in continuous movement, bring- ing each car into a glass-fronted show room at the tower's base. General Motors Building The part that automotive engineering has played in our civilization is graphically represented in the General Motors building. It stands on rising ground at the foot of Thirty-first street in the midst of a lovely, formal garden surrounded by willows and with Lake Michigan as its background. The building is an eighth of a mile long and 306 feet wide, sur- mounted by a 177-foot tower, brilliantly colored, and illuminated. It was designed by Albert Kahn. The entrance hall divides two main display rooms, each containing 18,000 square feet. Here the cars of General Motors are on exhibition. In one of the rooms the General ^Motors Research laboratories present a display of their own. The central feature of the building is a complete automobile assembly plant, to the rear of the display rooms, where 1,000 people at a time may witness the assembly of automobiles. Raw materials enter through one door and by the time they reach the opposite exit, they have become finished cars. A visitor may select the materials for his car as it enters the door, follow its progress along the assembly line, and get in and drive it off at the other side of the room. Sculptures — symbolizing the automotive industry, a huge mural painting, dioramas, exhibit areas for trucks and other General Motors CEHEtXL MOETOK The General Motors Building [51] products, a theater for the presentation of sound films, rest rooms and spacious lounge rooms are among the features of this building. The Chrysler Building Rising just north of the Travel and Transport building is the Chrysler building, with its lofty pylons giving it a commanding pres- ence. You will be charmed by the contrast its modern architecture presents to the ages old Maya temple across the drive, and by the interesting counter-balance it presents to the dome of the Travel and Transport building. In the circular section of the building are dis- played the latest models of the Corporation's various cars, together with cross sections of motors, demonstrations of tests for heat, cold and water resistance of motors. The terrace connecting this portion of the building with the display room at the north end offers an excellent vantage point for viewing the endurance and other tests which will be made on the proving ground to the west and serves as a roof for the space in which visitors will be permitted to inspect those automobiles which have been submitted to experiment. The Chrysler Motors Building [52 The Servant That Has Transformed The World Move southward along the shore of the lagoon, on Northerly island, from the Twelfth Street side, or cross Science Bridge, at Sixteenth street, and you will come to a circular court above which rises a bril- liant silver fan of light. In the court a fountain sends up iridescent jets of illuminated water in a series of multi-colored steps. Out of the center of the fountain rises a 70-foot canopy. The under side, of hammered cop- per, chromium plated, reflects the color and disseminates it, and achieves a superb beauty. This is the court of the Elec- trical building. The great building itself, in semi-circular form behind the court, connects with the Radio and Communication building. A group of pylons rises, with a giant bas-relief panel on either side, forty feet high, on which figures are sculptured in such mammoth size as to suggest the enormous forces they symbolize. One represents Atomic Energy, bearing the inscription: Energy is the substance o] all tilings — the cycles of the atoms, the play oj the elements are in forms cast as by a mighty hand to become the world's foundations. The other panel symbolizes Stellar Energy, and bears the inscription: Light is the beginning of all things. From the utmost ether it issues, shaping the stars, answering in its patterns to the majesty of creative thought. There is an entrance here, which leads to a great circular hall. .\nother entrance is on the west side from a water gateway, flanked by two huge pylons more than 100 feet high, and a wide stairway leading up to the hall. This water gateway provides a landing for visitors who come from the mainland by water across the lagoon. On these pylons also are sculptured figures. Light on the north pylon, Sound on the south one. Perhaps, if you come from the Hall of Science, where you are told that electricity is simply the movement of electrons, migrating away from the infinitesimal atom, the dazzling spectacle of Electrical [53] The Water Gate of the Electrical Building Court, and the illumination of its buildings, and the vast and spectacular compositions of light that flood the Fair may awe you by the very stupendousness of the story electricity tells in this phase alone of its myriad activities. But the story within these two buildings, of which Raymond Hood was architect, is more stupendous still. You Enter the Great Halls Twenty companies share the great hall, with a wide variety of exhibits, many spectacular. Here, for example, you will see demon- strated the new "fever machine," a gift of science to medicine with which hospitals are experimenting now, in the hope that it will be of Left— Lisht, A Plaque on the Electrical Building Right — Energy, Substance of All Things, a Plaque on the Electrical Building incalculable value in the treatment of many diseases. Photoelectric tubes — the "electric eyes" we have seen demonstrated so startlingly throughout the Fair — are made to do tricks that demonstrate countless possibilities. A high frequency furnace is shown, and you see a new blade quickly melted, while the hand which holds it, in the same furnace, is uninjured. [ 54 1 You see an incandescent light no larger than a grain of wheat, a marvelous aid to surgeons. Also the world's largest incandescent lamp, of 50 kilowatts. You see sun lamps as they are used in the poultry industry, and in hospitals, schools and offices. Beneath the floor, seen through a glass walk, a model section of the world's largest water-wheel generator rotates in a flood of light. Again, here is a huge model of a transformer, the largest ever built. There are extensive displays of electrical equipment and lighting effects, model kitchens, model laundries. Models of great ocean liners are paired with an open model of the electrical equipment that propels such liners. An Amazing Diorama On the mezzanine, the largest diorama in the world tells you a thrill- ing, inspiring story. Suddenly the great scene, 90 feet long, leaps into life. Reservoirs in the mountains take the flow from moving rivers, turbines begin to spin, across the plains lights in lonely ranch and farm houses glow in the dusk; the movement races on into a city that takes on life, the streets imbued with activities inspired by great industries, tall sky-scrapers, homes and hospitals, stores and factories, theaters, churches, rushing elevated trains and subways. A steam electric-gener- ating station with switchyards leading into it, and trains running; an air- port, and planes live. On to another city, from coal mines to farms, to quarries, to many other phases of industry now served by electric power goes the precious current. A voice speaks out of the darkness, explaining. And thus, in moving drama, you get the story of electricity from its generation, to its varied service of dispelling darkness, driving machines, and serving households in myriad ways, made possible by hydro-electric transmission. The first hydro-electric station in the United States was built just 50 years ago, near Appleton, Wisconsin! The diorama is a part of the Central Station Industry Exhibit, dis- played by the united power station companies of the nation. Other striking exhibits you see here on the second floor are full-sized rooms of homes, showing the many uses of electricity in the home; farm buildings, showing farm electrification — its uses on the farm from bug killing to silo filling and powering of machinery. Five model stores tell a graphic story. Electric furnaces that have made possible the utiliza- tion of cast iron, and other demonstrations of the applications of elec- tricity in power, heat and light in industry are shown. A Neon Display In space beneath the balcony you discover the absorbing process of filling tubes with the rare gases that make the brilliant colored lighting, so much of which you see utilized in the lighting of the Fair, and now used so extensively for advertising. An electric fountain features the space. Three striking demonstrations of illuminating effects tell some- thing of the future possibilities of this form of lighting. [ 55 1 2 '5 m E E o o The Radio and Communication Building When Raymond Hood planned this building, he had in mind the close relationship between communication and the industries devoted to generation, utilization and distribution of electric power. He symbolized their union by joining their buildings. Leaving the great hall of the Electrical building, you step into the radio show, where are demonstrated the mysteries and the fascination of world-wide reception. The small boy who has just begun to tinker with batteries and receivers, or the seasoned adult who has kept up with the swift develop- ment of this new science, will each find the points that interest them simply and graphically told. The show culminates in a display of novel and "trick" sets, and apparatus hinting of future developments. On the balcony of this connecting link, also, you will see a reproduction of a Hollywood movie set, and some interesting motion pictures of the World's Fair itself. Entrance to Radio and Communications Buildins (57 1 Inverted Speech and Masic Answer Board Entering the communication area, perhaps your attention might first be attracted by the "Bird Cage," where you see demonstrated what is called accoustical illusions. You speak in a low pitch, but you hear it high, and vice versa; you hear speech inverted so that it becomes unin- telligible when received over the ordinary radio set. In another exhibit you learn how privacy is obtained in radio telephone conversation. Other exhibits show you the mysteries of the dial telephone, and how operators handle your telephone calls. You see twelve conversations carried on simultaneously over a single pair of wires, and an oscilloscope shows you the wave form of spoken words, and then of musical notes. There's a magic answer board featured in the telegraph display. You push a button and get answers to your questions about telegraph service. Here, too, you see an historical exhibit of the development of the telegraph from Henry's electric bell of 1829, to Morse's relay and register of 1844 and other developments of his genius. Communications Garden One of the most impressive features of this building is Communica- tions Garden, fronting on the Lake Michigan side of the island, which may be reached from either floor level. These gardens give a modern impression of the immortal gardens of the Villa D'Este at Tivoli, near Rome. In the center four gigantic pylons rise like massed cypresses, more than 100 feet in the air. They will be visible far out into the lake and from points in the Exposition grounds on the mainland. In the base of these pylons are pavilions in which may be shown exhibits depicting the history of wire communication. Appropriate landscaping, trees, shrubs, grass, fountains and striking bits of sculpture make the gardens a delightful place for people to meet and keep appointments. You may spend hours in this great building, hours of fascination and delight, and perhaps of awed wonder that in less than a century all these miracles of electricity have come. And then turn perhaps with something of reverence to a building that sits on the edge of the Lagoon, adjoining these Electrical buildings — a memorial to Thomas A. Edison. The Edison Memorial It was in 1879 that Edison, watching a charred cotton thread in a glass bulb glow for 40 hours, ushered in the new era of light. Steinmetz, another great electrical genius, declared that Edison had done more than any other man to foster the growth of electrical engineering. And so tribute is paid to him, in the only building in the Exposition erected to the memory of one man, in the Edison Memorial. It houses displays setting forth the many evidences of his inventive genius, and their effect upon the world. ..\bout the building is a beautiful garden brought from Edison's home in Orange, New Jersey, where the "joyous inventor" spent most of his leisure time. [58] The Stirring Story of Mankind's Rise When you have finished your study and enjoyment of the story of the basic sciences — of their discoveries and their applications to man's material existence — you may cross the bridge from the Hall of Science, eastward, and see his beginnings, and watch his way unto the present day. On the north side of the two-storied Hall of Social Science which houses these exhibits, strikingly sculptured pylons will cause >ou to stop. At the left is a youth with two heads, with a goat by his side; flames rise from the figure depicting, in allegory, the Indian symbols Pylons and Hish Relief, North Entrance of the Hall of Social Science [59] for the (iod of Fire. At the right, is the God of Light, and next to it, a female figure representing Night, or Darkness, and next to this is the God of Storm. The figures are by Leo Friedlander. Within, you may read the history of man, and study the stages of his development. Perhaps you will find an answer to the perplexities of the present that cause our sometimes querulous questioning of the worthwhileness of things. A Story of Timely SisnlFlcance Fay-Cooper Cole, chairman of the department of Anthropology at the L^niversity of Chicago, who has had charge of the staging of this gigantic show, sums up the significances of the Social Science exhibits in these words: "At the end of the Sixteenth Street bridge, in the Hall of Science, and, in fact, throughout the Fair grounds, the visitor sees a century of progress in scientific achievement. At the other end of the bridge, in the Hall of Social Science, he can see the social consequences of this scientific achievement. The century of scientific progress has changed our whole social and economic life. It has changed our transportation, our whole method of living. "The old moorings are gone. We all feel somewhat at sea. The depression has most decidedly sharpened the interest of the public in social changes, and has brought home to it the importance of meeting them intelligently. We hope to show how social science tries to meet these great changes." So, it is a story of cause and effect that you will carry home with you from A Century of Progress. Here in the Social Science part of the story you can see, in dramatic sequence, the cave life of fifty thousand years ago, the life of the Mayas and aboriginal life as shown from mound excavations, and the life of the American Indian, the early American home, and on through the age of "oil lamps, horseshoes, wagon wheels and corsets," to the "age of electric lights, radios, automobiles and refrigerators." And you will find a simple but graphically told tale of capital and its distribution and redistribution; of the problem of immi- gration and overlapping governments, educational evolution and the latest methods of teaching; homes of ultra-modernity and, possibly, what they may be in the future; a model community and government. An American Family Is Central Exhibit As you enter the ground floor of the Hall of Social Science you are attracted by the visual story of an American family. Here is a group, almost life size, that shows a Colonial family. The women are spinning, weaving, and making the garments by hand. Other members of the group are drying fruits and meats. Through a doorway you see the father of the family breaking the sod with an old fashioned plow. [60] Aboriginal America— A Totem Pole from the Indian Exhibit Then the scene changes — a screen descends, and you are shown this home as part of a village, people have come to settle and the original family has acquired neigh- bors. Here is a church, a school and a court- house. You see the boggy road over which this family must travel, and on which a horseman and a stagecoach struggle. The limit of this group's horizon for a day is 50 miles. On the opposite side of this group ex- hibit is seen the family of 1933 living in a city apartment. There is the inevitable radio and the modern refrigerator; while on the shelf are cans of prepared foods. Most of the activities and amusements of the Colonial family have gone out of this home. The screen descends again. This same apartment appears on the map as a part of a gigantic building, and it in turn is part of a mammoth city, and you see its amusement places, parks, boulevards, play- , '-- ' grounds, schools and fac- tories; that miry road has become a smooth, mac- .i;!am highway. There's a railroad train. An airplane flashes across the skies. The daily limit of this family now extends to distant cities. Down the aisle to the left is the dramatic story of anthropology. Drama in a City Dump A huge relief map is the first exhibit, showing the nine culture areas of North America. Traveling lights on the map explain the significance of the exhibits outside the Hall of Social Science, and the methods of social scientists in determining the growth and development of cultures. Pause here and look upon a common city dump. Would you think it could tell a story? It does — a story that explains graphically how the past is read. Electric lights, radios, automobiles and a myriad of other things which we use daily contribute to the dump of 1933. In 1893, the castoffs of a city were oil lamps, horseshoes, wagon wheels and madam's stays. Xot only do you see in a flash the differences between the two eras, but also you realize how those who delve into the ages can read stories of other civilizations. Such a comparison helps you to live the past illustrated by the exhibits of anthropology down the aisle. [61] After the city clump, you see a section of a cave taken from Europe that reveals records of 50,000 years ago. For centuries it has been sealed in rock. You see exact reproductions of the mounds which Indians built in Central Illinois through three successive cultures — you see the skeletons of Indians long dead, accompanied by the objects that were buried with them. A stratified village site emphasizes how the records of the ages are steadily being discovered and read. Then Trace the Threads of Our Own Existence As you pass through the pages of history, you follow naturally the ramifications of our increasingly complex existence. You trace the economic aspects of industry, and of agriculture, and see the maze of distribution processes that deliver necessities, and luxu- ries to our doors. You see the reasons for the prices of things, the cost of making, and the profit. You see how a dollar is distributed and redistributed, multiplying into millions and billions, in causes of charity, in taxation. Complex things are made clear with simple exhibits that avoid the controversial and seek simply to show you the fundamentals of the scheme of things in the structure of world trade. Moving pictures and dioramas record the coming of peoples of other lands to the New World, to form cities within a city. The population grows, fed as a sea from countless streams. Such growth creates prob- lems of transportation, of industrial demands, of housing, of church A Maya Temple — The Nunnery at Uxmal [62 1 and of school, of varying social codes, of delinquency, of racial require- ments, of needs for recreation and of sanitation. Finding the solutions to these problems requires money, and the setting up of organizations for handling them. A variety of govern- ments may be functioning to care for the needs of only one small community. Moving lights show you the governm'^nts to which your money goes, and the estimated percentage of it actually returned to you. Maya Temple — Torn From A Thousand Years* Jungle Growth And now, from the broad terraces of the Hall of Social Science, lock away southward toward Thirty-First street, where the Maya Temple rises. When you come closer, like a pilgrim nearing a shrine, you may find it difficult to believe that this temple is an exact copy of a building in far away Yucatan, a temple at least ten centuries old, a bit of the 2,000 or more year old civilization of the Mayas. It stands on the highest ground within the E.xposition boundaries, its walls covered with elaborate designs, huge mask heads, and great serpents carved in stone. Tulane University, under the sponsorship of A Century of Progress, sent an expedition, in charge of Dr. Franz Blom, director of its depart- ment of Middle Western research, to Uxmal, ancient seat of Mayan culture, and there they obtained the information necessary for making an exact reproduction of one section of the famous "Nunnery." They brought back casts of its decorations to be incorporated in the Fair's temple. The Mayan civilization probably had its origin hundreds of years before the Christian era, in the highlands of Guatemala and Honduras. From there, apparently, it spread slowly into Yucatan, where its high- est development was reached about 1200 A.D. These people, without elaborate mechanical equipment built great cities in stone. On the tops of 200-foot rubble and cement pyramids, stood stately temples, government buildings, and astronomical obser- vatories, faced with cut stone and decorated with geometric designs and carvings representing men and animals. Decorative Detail, Maya Temple [63] We know that they developed hieroglyphic writing, that they had a mathematical system based on zero, and that they knew much of astronomy. They made use of several metals, especially gold. Some of their ornaments have been found ; beautiful mosaics, and lovely wood carvings. Descendants of the Mayas yet live, in Central America, but the civilization of their ancestors has vanished. Within the temple, priestesses kept the sacred fire burning; to let it die out meant death by stoning; and loss of chastity, death by arrows. They wove garments for the priests, who occupied large residences on tops of the pyramids, and for the idols. On festival days the idols were dressed in a glory of fine clothing, and gold and jade. And from this story of a vanished civilization you go out to view the living descendants of another civilization — the North American Indian. The Indian Villases To the north and across the pedestrian way, stretches the area in which the North American Indians live, during the Fair, in as close an approximation of their native life as it is possible to attain. A section of a Northwest Coast village is reproduced, with a plank house and carved totem poles. Next is one of the woodlands groups living in wigwams and practicing a limited agriculture. In contrast to these are the tipi-dwellers of the plains, whose greatest source of supply was the buffalo hunt. Then come the Navajo, roaming people, in some measure, and then the Pueblos, with terraced villages. The Golden Temple of Jehol [64] Interior The Golden Temple of Jehol [ r.5 ] All about these tribal homes swirls the colorful panorama of the Fair. And it's only a little way in steps — but centuries in time — to another striking display of life, the modern American home. The Bendix Lama Temple From the present with its daring structures of steel, embodying modern ideals of beauty and utility, you may travel swiftly through the centuries and halfway around the world to an alien shrine. It is the resplendent sight of the Golden Pavilion of Jehol, its gold- leaf roof glistening in the sunlight, that transports you to China of the Eighteenth century, with its culture and art that amaze and delight us today. It is placed westward from the Hall of Science, at Sixteenth street, like a jewel in a magnificent tiara. The Golden Pavilion, the original of which was built in 1767 at Jehol, summer home of the Manchu emperors from 1714 until the termi- nation of the dynasty twenty years ago, was brought to the 1933 World's Fair and the City of Chicago by \'incent Bendix, exposition trustee. Dr. Sven Hedin, noted Swedish explorer, acting for Mr. Bendix, spent two years in Mongolia before he selected this as the finest existing example of Chinese Lama architecture. Exact reproductions of the 28,000 pieces of which the Temple is composed were made and numbered at its original site in China. A Chinese architect was employed to interpret these marks and to direct their assembly on the exposition grounds. Chinese artists painted and decorated the finished structure. The Golden Pavilion is 70 feet square and 60 feet high, rising from a 4-foot pedestal. Its double decked roof of copper shingles is covered with $25,000 worth of 23-karat gold leaf. On the exterior, twenty-eight columns in red lacquer, 16 feet high, support the lower deck. Twenty- eight other columns, 30 feet high, form part of the wall. Inside, twelve 37-foot columns support the gilded ceiling and the upper deck. Carved grills, in red, blue, yellow and gold, enclose the glass window panes. The cornice beams are gilded and carved with images of dragons, cats, and dogs. Hundreds of pieces of carved wood form the ceiling. A Chinese guide, speaking excellent English, describes for you the treasures contained in the Temple. One of the interesting objects he points out is the "prayer wheel," which the devotees turn instead of repeating prayers. One turn of the wheel is the equivalent of many million prayers. There is an interesting temple drum, trumpets so long that the player requires the services of an assistant to hold them up, bronze and gilded wooden Buddhas, images of numerous other gods and goddesses, altar pieces, incense burners, trumpets, masks used in sacred dances, silver lamps, temple bells, and rare carpets. rr)6i Beautiful Homes of Today and Tomorrow H( ome Planning Hall Though not technicalh- a part of the Social Science group, a culrrii- nating chapter of the story could center in Home Planning Hall, and in the homes which make up the housing section of the Fair. North of Thirty-first street, Home Planning Hall and a group of eleven houses are designed to show progress in architecture, comfort and economy. Home Planning Hall is the general exhibits feature of the Home and Industrial Arts Group. It is devoted to exhibits of heating, plumbing. The Home Planning Hal [671 air conditioning, refrigeration, home equipment, household appliances and building materials. ('irouped around the l^uildings on the lake front, with appropriate landscaping, are eleven exhibit homes. Eight of them undertake to illus- trate in a modern way, to the family of limited means, the use of prefabricated builcHng units, new materials, and new methods of con- struction. All these small houses are designed without cellars and with integral garages. All but one are constructed with flat roof decks and solariums which make maximum use of sunlight for health and enjoy- ment. All seek to cut the cost of small home construction and provide greater living values. Most of the group were produced by manufacturers to illustrate use of their materials, yet architects and decorators have had full play in carrying out the theme of progress, wholly aside from the commercial factor involved. The houses in this interesting group are listed below: Brick Manufacturers' House Andrew Rebori, of Chicago, is the architect. The house was built by the Common Brick Manufacturers' Association, and demonstrates rein- forced brick construction. The house is built, virtually, in one piece: walls, floors, and ceilings, all of brick, are held together as a unit by steel rods run through the masonry. It has three stories with balconies on the two up[>er floors. The second floor includes the living room, dinette and kitchen, and the basement floor the cooling and heating plant. The third floor has two bedrooms, bath and porch, and the roof a recreation deck and garden. Cost, $4,500.00, exclusive of equipment. Interiors by the Brick ^Manufacturers' Association Armco and Ferro Enamel House This house was built for the American Rolling Mill Company and the Ferro Enamel Corporation, by Insulated Steel, Inc. This house is unique in that it is frameless; no structural steel being used. The walls are box-like units, factory fabricated, house high, and welded at the shop in various widths. When set up, the walls are filled with rock wool. The exterior is panels of vitreous enamel iron nailed on with "belyx" nails. There are seven rooms, bath and lavatory, and integral garage. The deck roof gives space for a solarium and open porch. There are four bedrooms on the second floor, with six large closets. The architect was Robert Smith, Jr., of Cleveland. Cost, exclusive of equipment, $4,500.00. Interiors by Kroehler Furniture Company and Ladies Home Journal. General Houses, inc.. House This is another all-steel, frameless house, with nothing made at the site except the concrete piers. The steel chassis was set in place, and the panels bolted on to form a complete shell; then the roof panels were bolted on, windows and doors installed, and the house was ready for [68] paint. It has been estimated by the General Houses, Inc., that these simple units make possible an almost endless variety of designs, and that a week's time could suffice for the erection of a four or five-room house. Howard T. Fisher, of Chicago, was the architect. Cost, exclusive of equipment, $4,500.00. Interiors by Kroehler Furniture Company. Good Housekeepins-Stransteel House Here is a steel frame house of highly modern design, with a large recreation room on the second floor. The exterior is enamel-finished steel, backed with Haydite and fastened with nails. Two bedrooms are on the ground floor. The large recreation room on the second floor gives access to the terrace, which covers the greater part of the flat roof. The architects were O'dell and Rowland of Detroit, Mich., with Dwight James Baum of Good Housekeeping Magazine as consultant. Cost, exclusive of equipment, $7,900.00. Interiors by Good Housekeeping Studio. Rostone House A six-room house built by Rostone, Inc., and the Indiana Bridge Company. Rostone is a building material composed of limestone and shale, and can be had in any color. The material is prefabricated in standard sizes. The house has all the living quarters on the first floor, with a glass-enclosed solarium occupying a fourth of the space of the roof deck, which covers the entire house. The architect was Walter Scholer of Lafayette, Indiana. Cost, exclusive of equipment, $6,000.00. Interiors by Thomas E. Smith, designing engineer, Chicago. Interior — The Stran-Steel House, the Recreation Room [69] "Design for Living" John Moore, of New York, was the architect and builder of this unusual house. It is of two stories; the first includes a large living room, with two L-wings, one a commodious dining room and the other a library study opening on a large porch. The upper floor holds two bedrooms with bathroom between. The full length of the house is occupied by a roof terrace, giving room for outdoor sleeping, and for recreation. Cost, exclusive of fixtures and equipment, ^4,000.00. Interiors by Gilbert Rohde, interior designer, New York. Masonite House This house was built by Masonite Corporation, with Frazier and Raftery, Chicago, as architects. It has a living room with 12-foot ceil- ing and large groups of windows on two sides. The dining bay is part of the living room, with a group of windows, centered by a French door, leading to a terrace. Two bedrooms and bathrooms are also on the first floor, with a wide hall and staircase giving access to the den upstairs and the covered and open decks of a modern roof. The walls of one of the bedrooms are covered with broad-loom woven cellophane, with hang- ings of knitted cellophane. Cost, exclusive of equipment, $7,500.00. Interiors by Marjorie Thorsh, interior decorator, Chicago, Lumber Industries House The National Lumber Manufacturers' Association built this house. It is a five-room dwelling, modern in design, and, differing from other houses in the group, has a pitched roof. The walls and ceilings are paneled with various woods, achieving unique designs and demonstrating logical lumber uses. Ernest Grunsfeld of Chicago v/as the architect. Cost, exclusive of equipment, $4,500. Interiors by Wolfgang Hoffmann, interior designer. New York. "House of Tomorrow" A circular glass house, incorporating possible indications of what the future may bring in housing has been constructed. The house is built around a central mast which contains all utilities. The exterior walls are of clear glass, and there are no windows. Privacy is obtained by drapes and roller and Venetian blinds. The most modern equipment available has been used, including everything from an airplane to electrically controlled doors. The furniture is especially designed. The ground floor includes the airplane hangar in addition to the garage; the roof above forms an extensive deck terrace, opening from the living room floor, and there is a similar deck around the drum-shaped solarium on the third floor. The ventilation is all by filtered, washed, heated or cooled air, recirculated every ten minutes. There are no visible light fixtures, as the necessary artificial light is indirect, from hidden sources. There are no closets, but movable wardrobes are used. The house has been built by Century Homes, Inc., and the architect [70] was George Fred Keck, of Chicago. The house is frankly declared to be a "laboratory" house, for the purpose of determining the attitude of World's Fair visitors to the idea of an utterly different home. Future homes of the type, it is said, could be built at prices within the range of the other small houses in the group, although price has been no object in building this house. In- teriors by Irene Kay Hy- man, interior decorator, Chicago. Florida Tropical House This is a house built to meet the requirements of people with larger means than average. It is designed for climates ap- proximating that of Flor- ida. There is a two-story living room overlooked by a balcony. The dining room is separate from the living room, being the Interior, "Design for Living' only full (lining room in the group. On the ground floor also are two bed- rooms and a large bath- room. A tile-paved log- gia is laid on the water side of the living room, connecting with the din- ing room. The roof of the house is a sun deck, living deck and recreation deck, e.xcept for the space taken by the upper half of the high room. Robert Law Weed of Miami, Florida, was the architect, and the cost, exclusive of equip- Building House of Glass ment, approximately $15,000. The striking and original interiors were designed by James S. Kuhne and Percival Goodman, Chicago and New York. [711 W. & J. Sloanc House This house, not designed to feature building methods, but rather to display elaborate interior decoration, was built by W. & J. Sloane of New York. It has a large living room with dining bay, gallery, three bedrooms, servant's room, kitchen and terrace, offering five opportuni- ties for exhibits of modern trends of furnishings and interior schemes. A garden at the rear is sponsored by the Garden Clubs of America. The Glass Block Building An unusual building has been built by the Owens-Illinois Glass Company as the landscape pavilion of the James W. Owen Nurseries, landscapers of the Home & Industrial Arts Group. This is a building of glass blocks, with a central shaft fifty feet high. The glass blocks are many colored, semi-transparent, and approximately the size of the ordinary paving bricks. The colors are fired into the glass. The build- ing houses a display of garden equipment and furniture, new and unusual flowers, and a complete display of the Owens-Illinois Glass Company. Southern Cypress Manufacturers — Johns-Manville — Crane Company — Kohler — The Southern Cypress Manufacturers' mountain lodge is in pleasing contrast to the other modern buildings of the group. Here will be seen an interesting story of the many kinds and uses of Cypress, "the wood eternal.'' The Johns-Manville building features a great mural, 90 by 20 feet, painted on asbestos-cement panels, and a colorful exhibit of products. This entire building is devoted to the interests of the family of larger means. The Crane Company bus station includes animated displays, showing the development of valves, piping, fitting, etc., to the present day of color in fixtures; with an advisory service to answer questions on bathroom planning and remodeling, while the Kohler Building to the north looks out over the Uahlia Garden with a colorful story of this firm's contribution toward the betterment of living conditions. A long colonnade with lounge chairs is surrounded by shops containing examples of bathroom furnishings. Gas Industries Hall Adjoining Home Planning Hall, to the south, is Gas Industries Hall, with exhibits showing the growth of the gas industry, in heating and cooking, and other uses. Developments in heating, plumbing, air condi- tioning and household equipment and appliances are featured, with a large display by the American Gas Association. 72] The Drama of Agriculture For centuries, men farmed mainly as their fathers had farmed before them. In the last 75 years, a great change has come. It is depicted in a dramatic way in the Agricultural group, over on Northerly island, just north of the U. S. Government building. Because of its great length, this building is easily reached, either over the Twelfth Street or the Science bridge. It covers a gross area of 95,115 feet and is 658 feet long. Arthur Brown, Jr., and Edward H. Bennett were the architects. The Dairy Building immediately north covers 15,000 square feet. The same architects designed it. A Semi-Tropical Setting Outside the buildings, you will see orange and lemon trees, grapefruit and other tropical and semi-tropical vegetation flourishing. It is a trans- planted exhibit from Florida as a part of the state representation. One of the finest collections of its kind ever assembled, it adds a note of e.xotic beauty to this group of buildings. There are roof terraces, fitted up as outdoor lounges, providing perfect vantage points for a view over the colorful lagoon, up and down the Fair. If you already have visited the Hall of Science, you will, in a measure, be prepared for the swift sequences of the stories of farm, food, dairy, and farm machinery. Biology has pointed the way to improve plants and animals by selec- tion and breeding, and to adapt them to new living conditions. Chemistry has taught us to banish or to put to good use insect life and fungus growths; to analyze the soil and enrich it. Physics has made possible larger and better cultivation by means of farm imple- ments, power to lighten the farm tasks, and to increase profits. Meteor- ology tells the farmer the best times to plant and harvest. Medicine plays its part in the prevention and cure of animal diseases. Today agriculture is a trinity — an art, a science, and an industry. Throughout this group you see the story of foods, their production, and preservation, and their distribution told by dioramas, moving mod- els, and actual processes. You see salt brought up from mines, and purified. You see how salt is obtained from the great flat beds near Salt Lake City. You see coffee and tea prepared; a model plant of a biscuit making factory; a great commercial kitchen, and its evolution from the primitive and old fashioned home cookeries; you see a popular drink actually made; and a miniature brewery to show how beer is made; the making of barrels for a multiplicity of purposes; how fish are caught and canned; how sugar is processed; bees at work in a glass hive, and the preparation and uses of honey. Livestock and Meat Industries The livestock and meat industries, forming one of the largest divi- sions of American agriculture, have combined to show you an interesting picture in the center wing of the Agriculture and Foods Building. Here a long facade flashes and changes with colorful lights. As you enter, your attention is caught first by the figure of the lone cowboy mounted on his horse, watching his herd at a water hole in the grazing grounds. Changing lights trans- form the scene alter- nately from night to day. At the left, a large dio- rama shows a modern feeding farm. The sun shines and there are lush corn fields. Moving trains of livestock cars are on their way to market. After you have seen a comparison of the 1833 and 1933 types of hogs and cattle, you enter into a white-tiled cooler to see how meat is cut and preserved. A retail store next claims you, where a robot indicates the choice cuts of meat, and gives a short talk on each. A revolving stage shows four scenes illustrating the values of meat diets. A great arch of a rainbow presents the pleasures of camp- ing, picnicking, and boating. Startling optical illusions show the com- ponent parts of a satisfying meat meal, changing suddenly into a healthy child playing. These highlights of the story of the livestock and meat industry are interspersed with striking depictions of the history of the two indus- tries, the distribution of meats, and the methods taken for protecting the public in the handling of meats. The Illinois Agriculture Building The State of Illinois presents a story of middle-western farming, and demonstrates the work that is carried on by the state to promote the industry, and to make life happier and more profitable for those who till the soil. [74 1 Decorative Detail, Asricultural Building 2 CQ [7S] Here is also j^iven a dynamic exhibit of one product, dwelling in obscurit}' for most of us, yet holdin<^ a place of such importance to agriculture and industry that it brings strikingly home the great work of science in developing a simple gift of the soil and turning it to num- berless uses. The soy bean comes into its own, for here you see how science takes it. crushes it, mills it or dries it, and turns it to more than fifty uses to feed man and beast. The International Harvester Buildins Go into the International Harvester building and you will see the quarter million dollar exhibit of the machines and implements which science and industry have devised to lighten drudgery. The Dairy Buildins and the Color Orsan If you begin your trip to the Agricultural group from the north rather than the south end, the sweeping main entrance of this big building is only a few steps from the north, or Twelfth Street bridge. You enter into a large lobb}'. Beyond is a cyclorama on which streams of color play, flowing over it in masses or in subtle shadings or clashes of startling contrasts. At an organ console, a player's hands finger the keyboard, causing the variations of color. The instrument is the Clavilux, or color organ, designed to play with color as musical instruments play with sounds. With the "color music" for accompaniment, a spectacle is presented in the darkened amphitheatre in several episodes, showing how, in one *^*^-!f^i^*' The Dairy Building [76 1 The Poultry Show of civilization westward, and today's organized dairy industry with its showing the bringing of the first cows to the Plymouth colony, the trek of civilization westward, and today's organized dairy industry with its scientific preparation, distribution, sanitation, and refrigeration of milk and milk products. After eight minutes of the pageant drama, wide halls brilliantly illuminated and containing artistic scenes invite you into Industry Hall. Transparent figure groups show the four ages of humanity — Childhood, Youth, Prime, and Maturit}- — and the effect of dairy products' diet on the physical and mental powers. A mechanical reproduction of a cow shows the animal as a chemical laboratory, manufacturing milk. You enter Commodity Hall, and witness the preparation of ice cream, cheese, butter, milk, and dry milks. An illustrated exhibit per- mits you to follow milk from the country receiving station to the refrig- erated tank car, to the receiving tank at the city milk plant, through the processes in the plant, and to the delivering wagon. A dairy restaurant overlooks the lagoon. Next to the restaurant on the same level are club rooms for members of the Century Dairy Club. The members are contributors to the dairy exhibition, which was pro- duced by Century Dairy E.xhibit, Inc.. with Dr. H. E. \'an Xorman, manager and president. A Poultry Show Near the Thirty-seventh Street entrance there is a poultry show, with an international egg-laying derby as the principal feature, cham- pion hens from twenty-eight States, from the Dominion of Canada, and four other nations, competing. The egg-laying contest started a month before the Fair opened, and will be ended two days before its close. Besides the egg-laying contest, there is an exhibition of specimen flocks of unusual varieties of domestic, and wild, land, and water fowl. [77] A Fairyland of Flowers Transformation of 424 acres of barren, sandy, man-made land — wrested from the bottom of Lake Michigan — into a garden spot of velvety lawns, hundreds of trees, shrubbery and brilliant fiower-beds was the task confronting landscape engineers and horticulturists at Chicago's 1933 World's Fair. The problem of landscaping confronting Messrs. Vitale and Geiffert, the landscape architects, could not be too carefully studied, for it is the landscaping which forms the setting of the Fair. Not only do the trees, terraces, hedges and gardens decorate and beautify each individual building, but they have been placed and designed so as to weld the entire exposition area into a complete and harmonious unit. Type of tree, shape of pool, variety of flower, height of hedge and terrace, massing of shrubbery, have all been carefully and subtly adapted to the type and architecture of the particular building which it decorates, so that each spot has its own unique place in the carefully designed pattern of the entire area. One of the first tasks was the transplanting of hundreds of trees. All of these trees, except the cedars, came from Illinois, and Fair visitors will be refreshed by the shade of avenues and clumps of maples, elms, lindens, horsechestnuts and lombardy poplars. There will be twenty acres of smooth, hedge-bordered lawn studded with green and flowering shrubs; and the delicate tracing of young vines will add to the charm of many of the walls of the buildings. Probably the most spectacular part of the landscape effects will be the flowers. Twenty-four thousand square feet of flower beds will be scattered about the grounds, planted in a fragrant and colorful profusion of heliotrope, geranium, marigold, petunia, snow-on-the-mountain, salvia, begonia, dusty miller, and ageratum. An Avenue of Color Stroll from the Hall of Science southward to the IJall of Religion through an "avenue of color," a walk 1,000 feet long. Its bordering flowers are three kinds of gladiola, early, middle and late. At either approach of the Sixteenth Street bridge will be another colorful display of gladiola. Dahlia and Peony Gardens On southward, the landscaping surrounding the Home and Indus- trial Arts group, with Dahlia gardens, flaunting their riotous color, may allure you, and the enormous peony beds will make a spot of soft bloom near the Lincoln f^roun. [781 Cloistereo Beauty — Cypresses and the Carillon, Hall of Science [79] Alpine Gardens Just south of the Twenty-third Street entrance are the Alpine Gar- dens, a half acre in area, with wide paths and terraces, and shade trees and evergreens. From the upper terraces water cascades down to a pool at the bottom, in which water lilies float, and goldfish besport them- . selves. The rock ledges are formed of beautiful weathered stone, and there are restful garden seats where you may sit and watch the kaleidoscopic scene of the Fair. Rare plants gathered from abroad can be enjoyed, such as the flower- ing onion of Thibet, the Cupid's dart from Greece, many varieties of lilies from China and Japan, a sedum from Russia and an excep- tionally rare fall flowering crocus. Tribute to Cermak In a special place of its own there's a little garden of twenty- five rose bushes, memorial to An- ton J. Cermak, martyred mayor of Chicago. Shortly before the shot of an assassin, intended for President Franklin D. Roosevelt, at Miami, Fla., so wounded Mr. Cermak that he died a few days later, Jan Bohn, noted horticulturist of Blatna, Czechoslovakia, boyhood friend of the late mayor, had christened one of his newest rose creations the Anton Cermak. Their friendship had been renewed when the mayor visited his native country, on a tour of Europe in the interest of the Fair. It was intended to have a bed of this variety planted on the World's Fair The Alpine Garden The Horticulture Building rsoi Crimson and White Cosmos grounds in honor of the Hving mayor — after his tragic death, the memorial garden was decided on. Here again is a garden of prairie flowers, forming a dooryard for a Lincoln log cabin. Here are California blooms, with a background of moun- tains and a California mission house, and a brook babbling a soothing course through a forest preserve gar- den, with shaded footpaths and rustic bridges. Northerly Island Crossing the bridge to Northerly island, the splendor of gardens and foliage continues. Whether it is the formal simplicity of shaded and hedge-bordered pool and paths of the courts of the Electrical and the Agri- culture buildings, the Italian garden Hanked by a row of prim tall trees, or the great garden of roses, your eyes will be delighted by the quiet and charm of these spots. Within the Horticultural Building You will have seen dioramas in man}- exhibits throughout the Fair, but in the Horticultural building, a concession to which an admission fee is charged, are different ones. Gardeners and florists have used real trees, real flowers, real brooks, to present scene after scene in dioramic settings. The first you will encounter as you enter the hall is a tropical scene, with tall trees, and a tangle of vines and vivid flowers. Another is a colonial home, and about it real moss, lilies of the valley and spacious lawns. Here is a southwest desert, with forbidding cactus abounding, and Joshua trees. Another is an Italian lake, rimmed by trees, and with flowers in front. Others are a winter scene in the Mich- igan woods, with cold winds blowing their chilly breaths upon great trees, a formal rose garden; a sixteenth century interior, with cunning flower arrangements, and through the windows an old fashioned garden is glimpsed. Concealed skylights flood the flowers with sunshine, or. when needed, the blossoms are bathed in ultraviolet rays, Irom lamps. 181 1 The Hall of Religion Near the Twenty-third Street entrance, and north of the Midway, or street of carnival, stands a unique building. It strives to express the spirit of modernism, that is the voice of the Fair, and the more mellow, more traditional spirit of holy things. Its tower-carillon chimes religious melodies, and within is a chamber of quiet, a chapel of meditation and prayer. It is the Hall of Religion. Here, the followers of many faiths tell the story of man's rise through '^ ■%»- • « Hit \0O /^USINESS rxmilives arc cordially invited to attend the exhibition of International Business Machines in the General Exhibits Building at the Century of Progress.
