impossible for one to turn and go in an opposite
direction, but in the few moments of our excitement as we turned and
twisted in clawing for the loop where Edith had been tied, we became
bewildered. We didn't know in which direction to turn in searching for
the lost one!

"What'll we do?" cried the Professor. "Do something! Quick! Find her!
Find her!"

I took a great breath and yelled her name into the darkness. The sound
thundered through the place like the noise made by a freight train.
Again and again I screamed it, and the million devils in the place
shrieked the name in mockery. I exhausted myself in my mad efforts to
send my voice to her ears.

Holman gripped my arm when I had worked myself into an insane frenzy,
and he begged me to be quiet.

"Barbara thought she heard an answer," he cried. "Listen! There it is
again!"

It was Edith! Her voice came to us like a thread of silver, and with no
thought of the bottomless crevices that might be in our path, we charged
blindly toward the spot from which her cry had come.

It seemed ages before we met her. The sounds puzzled us, but at last we
gripped her hands, and the Professor and Barbara, hysterical with joy,
sobbed their thanks into the gloom.

"I don't know how the rope became undone," cried Edith. "I didn't find
out that I had become separated from the rest of you till I attempted to
draw your attention to the waterfall."

"To the what?" I questioned.

"To the waterfall," repeated the girl. "Did you pass it? It is a
beautiful little waterfall, and the water flows over a white limestone
rock that makes it sparkle like so many fireflies in the dark."

I cannot explain what happened to me at that moment. Some veil within my
mind was torn away by the few words that the girl had uttered. I was
back upon Levuka wharf, lying under the copra bag where Holman had found
me, and for a moment I could not speak as the subconscious mind flung a
score of half-forgotten incidents into my conscious area.

_"It is the White Waterfall!"_ I yelled. "It is the White Waterfall
that the Maori sang of on the wharf at Levuka! He was warning Toni, and
Toni was killed by Soma because he knew! It is the way out! We're saved!
We're saved! It is on the road to heaven out of Black Fernando's hell!"

THE WIZARDS' SEAT

As we stumbled toward the spot from which came the sounds of running
water, the incidents of the preceding ten days seemed t
