ELECTRICITY AT WORLDS FAIR.
Monster Plants Will Make Effects
 Wonderfully Beautiful.

Incandescent electric lamps are used, for the most part, for the outside illum- ination at the Louisiana Purchase Expo sition at St. Louis.
 The greater number of these are at tached to the building structures them selves in such a manner as to bring out the architecture at night. in keeping with the general architectural scheme.
 The effect of a great number of incan- descent lamps in showing off the lines of the buildings emphasizes the extent of the structures themselves, as well as lends itself to an effective appearance The same quality of light given off by arc lights, projectors or other large can dle-power methods of Illuminating would produce a cold feeling not in keeping with the idea of an exposition.
 The waterways of the Exposition are of great extent and are thoroughly illumin- ated, as they are used for boat traffic at night as in the daytime.
 The main picture of the Exposition cov- CTS territory of 600 acres and is arranged in a setting shaped not unlike lady's fan. Three courts radiate from a common centre. This common centre is occupied by d territory known as the Cascades, made up of architectural, sculptural and hydraulic features, very ornate in de- sign, are placed along this curve and are connected by a colonnade at the crest of the terrace of States. The central place of this architectural setting Is occupied by Festival Hall, 200 feet high, while the smaller structures on either side, each 100 feet high are known as restaurants. In front of each of these three buildings is to be placed a motif from which a cascade of water issues. tumbling over a series of falls and finally reaching the lagoon.
 The daylight appearance in this terri tory relies for its effect on the skill of the artist and engineer in combining water effects with an architectural or sculptural setting.
 At night 1t is intended that this whole territory of the Cascades should be treated simultaneously with light effects The intention was not to simply trim structures and objects with lights, but that the entire territory should be built I'D. as it'were, of light itself. In the same manner the entire territory of the Cas- cades will partake of the color Of light applied by rendering the buildings as If they were light itself, and not simply the effect of light.
 One effect is to make the entire terri tory the color of an amethyst crystal, while at the same time, the Cascades will appear as illuminated by vari-colored lights for protector lamps. At another time, when the entlre nlIlSiue iS dh eHloI- ald color. the water will take on a phos- phorescent hue. Again, when the entire Cascade territory appears as solid in candescent thing, the waters of the Cas- cade will appear as sheets of molten sil- yer
 The lights are ever changing, not as though some operator was simply turning crank to produce recurring results in automaton fashion, but certain effects, prearranged, or portion of an evening" and the effects dissolved from one eff feet into another, according to program More than $50 cars were required to transport the necessary apparatus for the installation of the electrical machinery and It's accessories.
 The Expositybn has power plant of capacity of 10 500 horsepower installed in the Machinery building. This plant is complete with it's compliment of boilers and engines and uses briQuettes. made of bituminous coal and held together by a matrix of mineral pitch for fuel In ad- dition, the Exposition has rented 10000 horsepower from an outside source which Is delivered at the EXposition's fence lines. where it is taken and brought to the general switch boards in the Ma chirery building. The current supply from these two plants are so provided with switching apparatus as to make each plant interchangeable in whole or in part with the other. The scheme of illumina- ton of the entire Exposition has been worked out by Henry Hustln, chief of tho and b,raa,,
