wly revolve until once more for a
brief day the aperture in its wall would pass the corridor's end.

But in the meantime what horrible things would go on within that
chamber!

"Xodar!" I cried. "Can no power stop this awful revolving thing? Is
there none who holds the secret of these terrible bars?"

"None, I fear, whom we could fetch in time, though I shall go and make
the attempt. Wait for me here."

After he had left I stood and talked with Dejah Thoris, and she
stretched her dear hand through those cruel bars that I might hold it
until the last moment.

Thuvia and Phaidor came close also, but when Thuvia saw that we would
be alone she withdrew to the further side of the chamber. Not so the
daughter of Matai Shang.

"John Carter," she said, "this be the last time that you shall see any
of us. Tell me that you love me, that I may die happy."

"I love only the Princess of Helium," I replied quietly. "I am sorry,

For a few minutes we stood thus talking in low tones. Ever smaller and

A draught from above brought the fumes of smoke to our nostrils. As we
stood waiting for Xodar the smoke became thicker and thicker.
Presently we heard shouting at the far end of the corridor, and
hurrying feet.

"Come back, John Carter, come back!" cried a voice, "even the pits are
burning."

In a moment a dozen men broke through the now blinding smoke to my
side. There was Carthoris, and Kantos Kan, and Hor Vastus, and Xodar,
with a few more who had followed me to the temple court.

"There is no hope, John Carter," cried Xodar. "The keeper of the keys
is dead and his keys are not upon his carcass. Our only hope is to
quench this conflagration and trust to fate that a year will find your
Princess alive and well. I have brought sufficient food to last them.
