INTERIOR OF THE ELECTRICITY BUILDING.—How the world advances was perhaps better illustrated in the Electricity Building than in any other of the great structures on the grounds. At no previous exposition had there ever been a structure set apart for electrical exhibits and at none could there have been anything like the display here made. The marvelous advance in the use of electricity has been accomplished since Philadelphia and Paris did their best. Science and invention have but lately begun to fairly occupy this new world, but that the occupancy is already great was demonstrated by the magnificent showing made at the Columbian Exposition, a showing which in itself must result in promoting advancement in electrical discovery, bringing together as it did evidence of what those discoveries are to date, and conveying boundless suggestions for the future. The view given in the illustration is down one of the great center aisles of the building and conveys an idea of the general effect produced, though of course no print, even with the artist’s aid, can quite equal the beauty of the night exhibition, with the combined blaze of thousands of brilliant lights. The great pillar seen in the center is that up which lights in various colors seemed to climb continuously, and the nature of other objects is indicated to electricians by their form, though, so new is the science, that the layman may not in every case distinguish. Foreign countries were well represented in this great department, though, of course, the United States, the country of Franklin and Morse and Edison, took the lead.
