Tesla Builds A Marvel of Force

His Oscillator, He Declares, Will Transmit Without Wires Power Thousands of Miles.

MANY MILLIONS OF VOLTS.

He Says the Electrical Disturbance Caused by the Machine Will Be Felt All Over the Globe.

A ROARING, SILVER FLAME,

Nikola Tesla announced four years ago, that he had discovered a plan for transmitting intelligible signals and power to great distances. without wires, but his assertion was received with skepticism, notwithstanding he described the principles of his discovery in lectures before the Franklin Institute, In Philadelphia, and before the National Electric Light Association, in St. Louis.

Mr. Tesla, not discouraged, pursued his investigations, and now declares his discovery is capable of producing an electrical disturbance strong enough to be felt all over the earth. He says his discovery will not only make it possible to send messages, but also to transmit power without wires by I means of an immense electrical tension, measuring many million volts.

GIVES FORTH A ROARING, WHITE FLAME.

Mr. Tesla recently has given several demonstrations of his discovery. I saw the apparatus in his laboratory yesterday. It resembles a spider web of wires fastened to a black disk ten feet in diameter. The wires coine together in the centre, where there is a brass ball six inches in diameter. The machine, which its inventor calls an oscillator, is fastened to a wooden screen. Mr. Tesla allowed me to see the oscillator from a distance, but refused to give any technical description of it.

The wires are all arranged with perfect exactness, not varying a hair's breadth from the right position. When the machine is in action a roaring flame, resembling a stream of molten silver, breaks from the brass ball and shoots into the air for eight or ten feet. The noise made by the crackling flame is deafening. Power to operate the apparatus is obtained from an ordinary electric current. According to Mr. Tesla's theory, the earth and air being charged with electricity, his apparatus operates on the earth as would pumping air into a rubber bag. The disturbance from the machine is felt instantly all over the globe.

NO LIMIT TO ITS POWER.

This electrical disturbance travels on the alternating currents with which the earth and air are charged at the rate of several million miles a second. The inventor's idea is to take up the vibrations from his apparatus with a delicate instrument that makes them perceptible and intelligible in several ways.

Mr. Tesla told me that these, vibrations could not be directed to any given, place, but must radiate to every quarter of the globe. To send messages of a private nature, a code must be used. He said a machine built on a large scale would transmit great power through the upper strata of the air.

Mr. Tesla said this power could be transmitted, theoretically, to any distance. His invention, described in his own language, might be compared to a pump which forces electricity in and out of the earth, producing, a violent disturbance.
