As this volume goes to press, the preparations are about completed for holding a great Exposition at Buffalo, which promises to be second in importance only to the Columbian Exposition at Chicago, in 1893, so far as concerns undertakings of like character in America. The Columbian Exposition was a "World's Fair"; this at Buffalo is "Pan-American,"—an exhibition, that is, of the arts, the industries, and all the achievements in civilization of the peoples of the Western hemisphere, from Bering Strait to Cape Horn. Very nearly every country in North, South and Central America has taken a warmly interested part in the preparations for the Exposition, and many have erected special buildings for their exhibits. The States of the Union have likewise been active, and few of them will be unrepresented in the numerous buildings on the grounds. Cuba, Porto Rico, and the West Indies generally, as well as Hawaii and the Philippine Islands, in their new character as dependencies of the United States, are brought importantly into the scheme.
