If you wish to know what our own country showed, I may say that the most striking things were its inventions, machines that could do almost everything which the world wants done. And the newest and most wonderful of all these things was the telephone. This magical invention was shown there to the people for the first time, and the first voice shouted "Hallo!" over the talking wire. In the years that followed centennial celebrations became common. In 1881 the centennial anniversary of the surrender of Cornwallis was celebrated at Yorktown. In 1882 the bi-centennial (the two hundredth anniversary) of the landing of William Penn was celebrated at Philadelphia. A vessel that stood for the old ship "Welcome" sailed up the stream, and a man dressed like the famous old Quaker landed and was greeted by a number of men who took the part of Indian chiefs. In 1887 Philadelphia had another grand anniversary, that of the signing of the Constitution of the United States, which was celebrated by magnificent parades and processions, while the whole city was dressed in the red, white and blue. In 1889 New York celebrated the next grand event in the history of the nation, the taking of the oath by Washington, our first President. The next great anniversary was that of the discovery of America by Columbus, four hundred years before. This was celebrated by a wonderfully splendid exhibition at Chicago, the most beautiful that the world had ever seen. Columbus landed in October, 1492, and the buildings were dedicated in October, 1892, but the exhibition did not take place till the next year. Those who saw this exhibition will never forget it, and very likely some of my readers were among them. Its buildings were like fairy palaces, so white and grand and beautiful; and at night, when it was lit up by thousands of electric lights, the whole place looked like fairy land. The world will not soon see anything more beautiful. I cannot tell of all the exhibitions. There were others, at New Orleans, Atlanta, and other cities, but I think you will be satisfied with hearing about the large ones. The Centennial at Philadelphia set the fashion. After that, cities all over the country wanted to have their great fairs, and many of the little towns had their centennial celebrations, with music and parades, speeches and fireworks. During all this time the country kept growing. People crossed the ocean in millions. Our population went up, not like a tree growing, but like a deer jumping. In 1880 we had 50,000,000 people. In 1900 we had half as many more. Just think of that! Over 25,000,000 people added in twenty years! How many do you think we will have when the youngest readers of this book get to be old men and women? I am afraid to guess.
