Dr. Tesla Finds Ray to Kill Army at 100-Mile Distance

Discovery Reported to Make Defense Impregnable; Plans Gift to Arms Parley

New York, July 11 — (Associated Press) — The discovery of a force ray that would destroy an army 100 miles away, that would make A nation's defenses Impregnable, has been announced by the inventor, Dr. Nikola Tesla.

In the interests of peace, Dr. Tesla said he plans to place the ray at the disposal of the Geneva disarmament conference. He announced the invention yesterday, on the occasion of his 75th birthday.

The force ray, Dr. Tesla said, would consist of particles, driven electrically and projected in vast curtains, miles high and 100 miles long.

The speed of the particles — traveling at velocities of 50,000,000 volts — was described by him as giving the ray its destructive powers.

He said projecting plants, set up every 200 miles along a border, each shooting rays 100 miles on each side, would make the border impenetrable.

A fleet of 10,000 airplanes, flying into such a curtain, he said, would be destroyed.
