ELECTRICAL DISPLAY
Wonderful Advance Will Be Seen at
 Jamestown Exposition.

From the Bait Manufacturer Record.
 Distinct among such wonderful attrac- tions as the great army and navy rendez- vous, the international submarine races and the air ships contests at the James, town Exposition will be the magnificent electrical illumination and display. Elec- tricity will be the most important factor throughout the exposition The grounds will be dazzling under the brilliant light of thousands of electric lights. The illu- imitation of the greatest harbor in the world will surpass anything of its kind ever attempted. Thousands of small craft hundreds of large ships and steamers and the huge men-of-war will be gay with many colored lights, and powerful cleo trical searchlights will streak the heavens over Hampton Roads.
 It is expected that the electrical illumi- nation of this exposition will even sur pass the wonderful effects obtained at the Pan-American. In no other industrial fiel1 in the world have there been such strides in the past few years as in cleo tricity. Visitors will be shown the very latest inventions and discoveries in wire less telegraphy, wireless telephony, cleo srical heating and power. Their hunger will be satisfied with food cooked in elec- trical utensils; they will be shown hund- reds of new motor-driven labor saving devices and a large number of novel ap- plications of the electrical current
 For the first time a national exposition wilt be entirely operated by electricity furnished by modern steam turbines These new rotating steam turbines have many advantages over the old recipro- eating engines, and this is especially true in the development of electrical current. The Norfolk Railway & Light Co. has contracted to furnish all the electricity required for illumination and power pur- poses. The addition of the load has made necessary a large increase in the equipment, and a very large Curtis tur- bine generator units have been purchased. The electricity will be transmitted from Norfolk to the exposition grounds on a specially constructed line, and will be transferred and distributed through a large substation in Machinery Hall. This substation will be model of its kind, and represents the engineering practice in such work. Here will be located large air-cooled transformers for trans forming the current used in the general illumination of the grounds and build ings. Another type of transformer con- trols the current for the arc lamps used for police lighting. Tn this building will al-o bs located powerful motor generator sets, which will provide direct current of suitable voltage for the operation of searchlights and small motors.
 The switchboard for controlling the electricity used on the grounds will be located on an elevated platform, and is the product of the highest class of engin- eering construction Following the ex- ample of all the recent national exhibi- tions the Edison lamp will be used in Illuminating the grounds and buildings. The General Electric Co. will furnish the entire electrical equipment, including a number of the naval type of search lights, to be used from the highest build ings in conjunction with the display of powerful lights from the naval fleets.
