s fearful that
in his terror he would betray them. "Fear not," he whispered, "we
are your friends."

At last the Negro spoke in a low whisper, scarcely audible even to
the keen ears of the ape-man. "What," he asked, "can poor Otobu do
for the god who speaks to him out of the solid wall?"

"This," replied Tarzan. "Two of us are coming into this room. Help
us prevent this man and woman from escaping or raising an outcry
that will bring others to their aid."

"I will help you," replied the Negro, "to keep them within this
room, but do not fear that their outcries will bring others. These
walls are built so that no sound may pass through, and even if it
did what difference would it make in this village which is constantly
filled with the screams of its mad people. Do not fear their cries.
No one will notice them. I go to do your bidding."

Tarzan saw the black cross the room to the table upon which he

as much as to say, "Master, I am ready."

Without more delay Tarzan threw aside the hangings and stepped
into the room. As he did so the young man rose from the table to be

arm before she could interfere with Otobu's attentions to the young
man. At first, as she turned toward the ape-man, her face reflected
only mad rage, but almost instantly this changed into the vapid
smile with which Smith-Oldwick was already familiar and her slim
fingers commenced their soft appraisement of the newcomer.

Almost immediately she discovered Smith-Oldwick but there was
neither surprise nor anger upon her countenance. Evidently the poor
mad creature knew but two principal moods, from one to the other
of which she changed with lightning-like rapidity.

"Watch her a moment," said Tarzan to the Englishman, "while I disarm
that fellow," and stepping to the side of the young man whom Otobu
was having difficulty in subduing Tarzan relieved him of his saber.
"Tell them," he said to the Negro, "if you speak their language,
