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.

A very interesting group constituted the electric motors and their
manifold applications as to street and other railways; to mining, to
elevators, pumps, printing presses, and domestic appliances.

The creation of light by electricity was beautifully elucidated by the
weird illumination of the Edison Light Tower in the center of the
building, and the Egyptian Temple in its south-eastern portion. Countless
incandescent lamps were glowing in all the colors of the rainbow. The
luminary effect gave us the impression as if a fiery serpent was
