same dull red glare of light that, to a fainter degree, gave us the
effect of afterglow. But we were not floating; we were anchored as
securely as a ship riding in a calm harbor.

We turned back to Fraser, amazed, awed, bursting with questions.
Madman he might be, but he had wrought a miracle.

"I will explain," he said and his eyes gleamed with pride. "Of course
you know of my tremendous discoveries connected with the power of
light. At any rate, five years ago, the scientific world on earth
thought they were tremendous. In reality that was nothing to my
amazing strides in the past three years. There is nothing that cannot
be done with light! Nothing!" For the first time Fraser's eyes became
alive. They were illumined. His whole body seemed to radiate light and
fire and genius. We listened, fascinated.

"Take, for instance," he continued eagerly, "that ray with which I
drew you and your plane to me. That ray is the pure power of
magnetism. At full strength it will draw anything to it instantly.
Fortunately the power can be regulated: I can switch a lever in my
laboratory and draw things to me, via the ray, at any speed I
wish--one hundred, two hundred, a thousand miles an hour."

"How far can you throw the ray?" asked Foulet, and I knew he was
thinking of that glider that rose from the roof-tops of
Constantinople. Fraser also knew he was thinking of that.

"I did not draw the glider," he said quietly. "The airplane I sent did
that. My airplanes carry batteries of this ray. In the beginning I
found gliders to be more practical for my purposes than airplanes. For
one thing they were silent. My only problem was that of getting them
off the ground. Once they were in the air I could manage everything.
It was this problem that inspired this discovery and perfection of the
ray. But, you asked how far I can throw the ray? This main lamp, that
I operate myself from here, is effective at two hundred miles. At one
hundred miles it enjoys its full power."

"And you can draw anything to you," asked Brice, "within the radius of
the magnetic ray?"

"Anything in the air," answered Fraser. "But of course I must use
caution. Great caution. If I drew planes to me indiscriminately I
would draw attention to myself; my secret and my location here would
leak out. No. That must not be. So the only planes I bring are my
own--and yours." He paused and his black eyes, again glassy, swept
over u
