 The Cavalcade of America, presented by DuPont. Better things for better links through chemistry. That phrase expresses the objective of every member of the DuPont organization. And DuPont now invites you to another evening of the summer musical series in the Cavalcade of America. Arthur Meyer, America's foremost bandmaster, is with us again with his concert band. He is here to present interesting examples in the history of musical development in America from the gay 90s on. On April 7, 1889, as a desire to encourage literary expression in the public schools of Washington, the Washington Post offered places for essays written by the students of the capitals. John Philip Sousa, then the leader of the United States Marine brand, was asked to write a march in Memoration of the Occasion, and to play it for the first time on the day the prizes were awarded. Mr. Sousa was greatly pleased with the idea, and the result was the famous Washington Post march, which Arthur Pryor and his band will play as an open selection. In the gay 90s, the two-step was America's most popular dance, and Sousa's marches, especially the Washington Post, were in great demand. In Europe, the Washington Post march became such a symbol of that particular dance that the dance step itself was known as a Washington Post. At the World's Fair in Chicago in 1893, Theodore Thomas, famous orchestra conductor, was named as director of music, and during the spring and summer, Sousa's band was engaged to play at that famous exposition. This evening, we won't re-enact an incident that took place that summer while Sousa's band was playing one of its concerts. Thousands of people attended each appearance of Sousa, but we will listen to one couple, a man and his wife, for in Chicago, doing the fair. They are seated in the rear of the opera theater. Joe? Yes? It's great, isn't it? Well, of course it is. It's Sousa's. I mean, it's great after a day at the exhibit and seeing the midway from one end to the other just to relax and listen to good music. Sure. Hey, Emma, where do you think you are? Hush, hush. What's the matter? You were singing with a band. I can't help it, Joe. It makes me want to sing. Oh, you'll annoy everyone around us. Is it any worse than you keeping your foot going? Well, I can't help keeping time to a band, but you don't have to sing. I'm sorry. Quiet, please. Quiet. Everybody's looking at us. Oh, dear. See that man back there walking out of the way? I hope he isn't calling an usher to put us out. The man who heard the conversation of his unidentified couple was Mr. Tomlens, the assistant musical director of the exhibition. And during the intermission, he speaks to John Phillips. You know, Mr. Sousa, when you were playing one of those numbers, there are a lot of people who had all they could do not to sing along with you. Tomlens, that's an idea. Everyone likes to sing. Do you mind if I try something? Well, I know, Mr. Sousa. Second part, Mr. Sousa. Coming. We'll see how this works, Tomlens. Ladies and gentlemen, our next number is a medley of popular songs. We go to ask you all to sing along with us. I'm sure you know all the words, and if you don't, just sing anyway. We'll start with two little girls in blue. During the engagement of Sousa's band at the World's Fair, it was repeated many times. And today, just as in the gay 90s, the rhythm of the band is contagious, whether it's a great concert organization or the little street band on the corner. One of the most popular of all band tunes is the National Emblem March by E. E. Bagley, which Arthur Pryor and his band will now play. It's a Chicago World's Fair with a successful midway amusement park sprang up throughout the country. To many of us, this would be a true impression of an amusement park. It's complete without its bandstand, where people can sit in the open and listen to their musical favorites. Many of our parks eliminate the concessions and similar features and specialize in musical entertainment only. New Jersey for the millions has heard at Willow Grove outside Philadelphia, Asbury Park, New Jersey, Revinia Park, Chicago, the Zoo at Cincinnati, Delma Gardens at St. Louis, Long Beach, California to mention some of the better known parks. The band has done much to make us familiar with the works of the great masters and also the delightful operettas such as the Vagabond King by Rudolph Trimmel. Arthur Pryor and his band will play selections from that stirring and tuneful musical comedy. Many people still believe that the band plays mostly marches, but in the repertoire of every band are a number of musical compositions that are written especially for band instrumentation. They are called descriptive and without one of them no band concert is really complete. Such a selection is the hunting scene by Bukalasi, which is brought to us by Arthur Pryor and his band, who made entirely of brass instruments with a pipe and drum core on the side and were incapable of the delicate shadings of a modern concert band. A beautiful example of the colorful possibilities of instrumentation for a concert band is found in Friedemann's Slavonic Rhapsody as interpreted by Arthur Pryor and his band. Story of Chemistry The scene is on a very dusty country road it's Sunday afternoon father and mother hope for a spin in their big touring car complete with gas headlamps and everything. Come to our dock father we'd better be getting back home. All right. The lane to turn around in. Well, there's one right here. Yeah, sure enough. What now? The tire blew up. Tire? Are we causing trouble? No, wait a minute. Hold on. Not these four new ones. Look at the mileage we've had without a single bit of trouble. Almost 2,500 miles. 2,500 miles. Why, that's wonderful, isn't it? It's very good mileage. There's no mileage like that in the old days. But today it's a different story. A recent issue of the Saturday evening post gave some interesting then and now figures about tires. For instance, in 1910 a tire that would run 2,500 miles cost about $25. Today a tire from which we expect 15,000 miles and often gets 30,000 can be purchased for about $12. Think of it. A 10 times the mileage at less than half the cost and with greater safety every mile. What brought about this startling improvement? Well, the greatly improved methods employed by tire manufacturers, of course and products of chemical research. Let's look at the way an old tire and a new one are made. The old tire had to be cured or vulcanized three or four hours. Thanks to chemical products called accelerators the new tire is vulcanized in a tenth of the time. The quality of the rubber and at the same time helps reduce the cost of the finished product. The old tire as many of you remember cracked and began to deteriorate after a period of exposure to the elements especially hot sun. Well, the new tire doesn't suffer that way because research has contributed chemical products called antioxidants which exists the action of oxygen. That means they help the new tire stand up much better under heat and the constant flexing under low pressure tires have to take every time the wheel goes round. So today's tires not only carry you much, much farther but practically eliminate the old time bugaboo of tire trouble and give you greater safety and comfort at a cost few dreams possible 25 years ago. Dupont Chemists working with the rubber industry have perfected a number of the chemical products which play such an important part in improving the rubber used in tires and other articles from elastic bands to hot water bottles. This work, contributing as it does to the daily comfort and convenience of all of us, provides one more illustration of the Dupont pledge better things or better living through chemistry. Next week at this same time, our program will tell stories of American bands at home and abroad. Arthur Pryor and his band will again be heard when Dupont continues the first group in its summer musical series in America. Columbia Broadcast
