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.

As our people increased in number they spread more widely over the country. Railroads were built everywhere, steamboats ran on all the streams, telegraphs and telephones came near to every man's front door, the post-offices spread until letters and newspapers and packages were carried to the smallest village in the land. Nobody wanted to stay at home, in the old fashion. People thought nothing of a journey across the continent or the ocean. Wherever they were, they could talk with their friends by letter or telegraph, and they could go nowhere that the newspaper could not follow them.

So the waste places of the country began rapidly to fill up. If you have ever seen an old-time map of our country you must have noticed places in the West marked "great desert," or "unknown territory," or by some such name. But people made their way into these unknown regions and filled them up. First they went with their families and household goods in great wagons. Then they went far more swiftly in railroad trains. Here they settled down and began farming; farther on, where there was not rain enough to farm, they raised cattle and sheep on the rich grasses; still farther, in the mountain regions, they set to work mining, getting gold, silver, copper, iron and coal from the hard rocks.

Cities grew up where the Indian and the buffalo had roamed. The factory followed the farmer; the engine began to puff its steam into the air, the wheels to turn, the machines to work, goods of all kinds to be made. The whole country became like a great hive of workers, where everybody was busy, and thousands of the people grew rich.

But all this great western country was not given up to the farmer, the miner and the wood-chopper. There were places which nature had made beautiful or wonderful or grand, and these were kept as places for all the people to visit. One of these was the beautiful Yosemite Valley, in California; another was the wonderful Yellowstone Park, with its marvelous spouting springs; others were the groves of giant trees; still others were great forests, from which the government told the wood-choppers to keep out, for the woods had been set aside for the good or the pleasure of all the people of the land.

Some of you may ask, what became of the old people of the country—the Indians, who were spread all over the West? There were hundreds of tribes of them, and many of them were bold and brave, and when they saw the white men pushing into their country they fought fiercely for their homes. But they could not stand before the guns of the pioneers and the cannon of the soldiers, and in time they were all forced to submit. Then places were set aside for them and they were made to live in them. The Indians were not always treated well. They were robbed and cheated in a hundred ways. But that, I hope, is all over now, for they are being well cared for and educated, and they seem likely, before many years, to become good and useful citizens of our country.
