retrace that difficult three days' trail. They talked together in
low whispers, and one turned toward the jungle, calling aloud to
the voice that had spoken to them from out of the foliage.

"How do we know that when you have us in your village you will not
kill us all?" he asked.

"You do not know," replied Tarzan, "other than that we have promised
not to harm you if you will return our ivory to us. But this you
do know, that it lies within our power to kill you all if you do
not return as we direct, and are we not more likely to do so if
you anger us than if you do as we bid?"

"Who are you that speaks the tongue of our Arab masters?" cried
the Manyuema spokesman. "Let us see you, and then we shall give
you our answer."

Tarzan stepped out of the jungle a dozen paces from them.

"Look!" he said. When they saw that he was white they were filled
with awe, for never had they seen a white savage before, and at
his great muscles and giant frame they were struck with wonder and
admiration.

"You may trust me," said Tarzan. "So long as you do as I tell
you, and harm none of my people, we shall do you no hurt. Will you
take up our ivory and return in peace to our village, or shall we
follow along your trail toward the north as we have followed for
the past three days?"
