The intramural
railway demonstrated the latest application of electric motor power to
elevated railroads.
The illumination of the grounds and buildings showed the marvelous
progress achieved in electric lighting, and the expertness in obtaining
brilliant spectacular effects. The electric launches on the lagoons
manifested the usage of electricity for water-transportation.
All these practical exhibits represented purely commercial features,
whereas the displays in the building--we just had entered--offered a field
of relevations as regards the extraordinary accomplishments in the
electrical science. They embraced all the improvements from the earlier
inventions to the latest marvels.
In the southern portion of the main floor, the United States showed
various devices for creating the three economic commodities--light, heat,
and power.
With great interest we inspected the numerous apparatuses illustrating the
phenomena and laws of electricity--the instruments for electrical
measurements--the electric batteries--and the machines for producing
electrical currents by mechanical power. How transmission and regulation
of these currents are effected, could be studied by a vast number of
devices.
