The four hundred years of the New World's life closed its chapter of happiness in the electric lights and brilliant sunshine of the marvelous White City by Lake Michigan. It is a continued story of daring, devotion and progress, that the boys and girls of America should never tire of reading. And this story was made possible and turned out so well, because of the briefer, but no less interesting story of the daring, the devotion and the faith of the determined Genoese sailor of four hundred years ago, whom men knew as Don Christopher Columbus, the Admiral of the Ocean Seas.
