It was in the year 1492, that a daring sailor, named Christopher Columbus, crossed a wide ocean and came to this new and wonderful land. Since then men have come here by the millions, and the mighty nation of the United States has grown up with its hundreds of towns and cities. In one of these, which bears the name of Chicago, the grand Columbian World's Fair was held, in honor of the finding of America by the great navigator four hundred years before.
