The Exposition Fireworks are under the direction of William D'A. Ryan,
Chief of Illumination. On each occasion a set program is followed
consisting of twenty-four numbers. At the opening, a salute of ten
detonating bombs and a large rocket announce the event. This is followed
by features of the scintillator lights, combinations of these with
steam, with smoke bombs and with orange showers and Japanese daylight
shells, and by fancy star shells, festoon rockets and candle fountains.
The climax is reached in the Zone Salvo when a tremendous explosion of
hundreds of detonating devices occurs, with rockets and star shells
exploding in the air, the rays of the scintillator coloring the smoke
clouds in brilliant hues; and amidst it all, high above, suddenly
appears a beautiful American flag caught and followed by the ray of a
powerful white searchlight as it floats away from sight.
