THE WORLD’S EXPOSITION
AND NEW ORLEANS.	IS
The main building is the largest ever erected. It is 1,378 feet long by 905 feet wide, without courts, and has a continuous roof composed largely of glass so arranged as to afford an abundance of light without subjecting the interior to the direct rays of the sun. Within, the view is unobstructed. From one side or corner of the building to its opposite, the interior, showing all phases of industrial activity, is seen. There are no partitions, and the lofty pillars, wide apart, supporting the roof structure, present no impediment to one's vision, but only serve to assist the eye in measuring the vast expanse. The interior is surrounded by wide and spacious galleries, twenty-three feet high, which are reached by twenty elevators having the most approved safety appliances, and by convenient stairways.
The machinery department occupies a space of 1,378 feet long by 300 feet wide, within the main building, and has an extension added in iron 350 feet long and 150 feet wide for heavy machinery, described under the heading of Factories and Mills. From the galleries overlooking more than two miles of shafting can be seen driving every known character of machinery.
Music Hall, with a seating capacity, in commodious chairs, for
11,000	people, a platform capacity for 600 musicians, and a mammoth organ, built to order for the Exposition, occupies the center of the interior.
The main building will contain general exhibits. It is situated (as will be seen by the park plan published herewith) about in the center of the grounds.
