ime we find a race consisting exclusively of
females. But here is the point. The secret of this chemical formula
is kept by a single race of Mahars. It is in the city of Phutra, and
unless I am greatly in error I judge from your description of the
vaults through which you passed today that it lies hidden in the cellar
of this building.

"For two reasons they hide it away and guard it jealously. First,
because upon it depends the very life of the race of Mahars, and
second, owing to the fact that when it was public property as at first
so many were experimenting with it that the danger of over-population
became very grave.

"David, if we can escape, and at the same time take with us this great
secret what will we not have accomplished for the human race within
Pellucidar!" The very thought of it fairly overpowered me. Why, we two
would be the means of placing the men of the inner world in their
rightful place among created things. Only the Sagoths would then stand
between them and absolute supremacy, and I was not quite sure but that
the Sagoths owed all their power to the greater intelligence of the
Mahars--I could not believe that these gorilla-like beasts were the
mental superiors of the human race of Pellucidar.

"Why, Perry," I exclaimed, "you and I may reclaim a whole world!
Together we can lead the races of men out of the darkness of ignorance
into the light of advancement and civilization. At one step we may
carry them from the Age of Stone to the twentieth century. It's
marvelous--absolutely marvelous just to think about it."

"David," said the old man, "I believe that God sent us here for just
that purpose--it shall be my life work to teach them His word--to lead
them into the light of His mercy while we are training their hearts and
hands in the ways of culture and civilization."

"You are right, Perry," I said, "and while you are teaching them to
pray I'll be teaching them to fight, and between us we'll make a race
of men that will be an honor to us both."

Ghak had entered the apartment some time before we concluded our
conversation, and now he wanted to know what we were so excited about.
Perry thought we had best not tell him too much, and so I only
explained that I had a plan for escape. When I had outlined it to him,
he seemed about as horror-struck as Perry had been; but for a different
reason. The Hairy One only considered the horrible fate that would be
ours were we discovered; but at
