"Where are you going?" asked the stranger, again.
"We are going to the Ghenzi Mountains now," replied Smith.
"Say, who the hell are you, anyhow?" demanded the "Gunner," "and what business is it of yours where we go?"
The stranger ignored him and turned again toward Smith. "Be very careful in the Ghenzi country," he said. "There is a band of slave raiders working there at present, I understand. If your men learn of it they may desert you."
"Thanks," replied Smith. "It is very kind of you to warn us. I should like to know to whom we are indebted," but the stranger was gone.
As mysteriously and silently as he had appeared, he swung again into the tree above and disappeared. The two whites looked at one another in amazement.
"Geeze," said Danny.
"I fully indorse your statement," said Smith.
"Say, Ogonyo," demanded the "Gunner," "who was that bozo? You or any of your men know?"
"Yes, bwana," replied the headman, "that was Tarzan of the Apes."
