“All substance is of a very transitory reality. Everything is in a constant state of change. A substance builds up, or it breaks down. Or both simultaneously; or sometimes one and then the other.”

“Electricity—” I began.

“Electricity,” he interrupted, “as they used to know it, is in reality nothing but a concentrated stream of particles—electrons, intimes, call them what you will—moving from one substance to join another. Lightning is the same thing. Such a stream of articles, Leonard, is a tangible manifestation of gravitational force. They had it right before them, unrecognized. They called it, ‘magnetic force,’ which meant nothing.

“How do these streams create an attractive force? Conceive the earth and the moon. Between them flow a myriad stream of infinitesimal particles. Each particle in itself is a vortex—a whirlpool. The tendency of each vortex is to combine with the one nearest to it.

“They do combine, collide, whirl together and split apart. The whole, as a continuous, violently agitated stream, produces a continuous tendency toward combination over all the distance from the earth to the moon. The result—can’t you see it?—must be a force, an inherent tendency pulling the earth and moon together.

“Enough of such abstract theory! A while ago, I charged that little model of this building with an Elton ray. The model, and this building itself, are built of an ore of electrite, the one hundred and fortieth element, as they called it when it was isolated a few years ago.

“You saw the model of the building glow? Electrons and intimes were whirling around it. The force communicated to the tiny projectile lying inside. In popular language, ‘its gravity was destroyed.’ Technically it was made to hold within itself its inherent gravitation and the gravitation of everything else was cut off. It was, in the modern sense, magnetized, in an abnormal condition of matter.”

I said, “There was a red ray from the little building. The projectile seemed to follow it.”

“Exactly,” he exclaimed. “That was the Elton Beta ray. It is flung straight out, whereas the Alpha ray is circular. The Beta is a stream of particles moving at over four hundred thousand miles a second. More than twice the speed of light!”

He chuckled. “When they discovered that, Leonard, the Einstein theories held good no longer. The ray bombarded and passed through the electric wall of the room, and the projectile went with it, drawn by it, sucked along by the inherent force of the flying whirlpools. The projectile with its infinitely greater mass than the mass of the flying particles of the ray, picked up speed slowly. But its density was lessening.
