Little Nkima had travelled far. Around his neck was a stout thong, supporting a little bag of leather, in which reposed a message. This eventually he had brought to Muviro, war chief of the Waziri; and when the Waziri had started out upon their long march, Nkima had ridden proudly upon the shoulder of Muviro. For some time he had remained with the black warriors; but then, at last, moved perhaps by some caprice of his erratic mind, or by a great urge that he could not resist, he had left them and, facing alone all the dangers that he feared most, had set out by himself upon business of his own.

Many and narrow were the escapes of Nkima as he swung through the giants of the forest. Could he have resisted temptation, he might have passed with reasonable safety, but that he could not do; and so he was forever getting himself into trouble by playing pranks upon strangers, who, if they possessed any sense of humor themselves, most certainly failed to appreciate little Nkima's. Nkima could not forget that he was friend and confidant of Tarzan, Lord of the Jungle, though he seemed often to forget that Tarzan was not there to protect him when he hurled taunts and insults at other monkeys less favored. That he came through alive speaks more eloquently for his speed than for his intelligence or courage. Much of the time he was fleeing in terror, emitting shrill screams of mental anguish; yet he never seemed to learn from experience, and having barely eluded one pursuer intent upon murdering him he would be quite prepared to insult or annoy the next creature he met, especially selecting, it would seem, those that were larger and stronger than himself.

Sometimes he fled in one direction, sometimes in another, so that he occupied much more time than was necessary in making his journey. Otherwise he would have reached his master in time to be of service to him at a moment that Tarzan needed a friend as badly, perhaps, as ever he had needed one before in his life.

And now, while far away in the forest Nkima fled from an old dog baboon, whom he had hit with a well-aimed stick, Michael Dorsky approached the tent where Nkima's master lay bound and helpless. The five minutes were up, and Dorsky had come to demand Tarzan's answer. He came alone, and as he entered the tent his simple plan of action was well formulated in his mind.

The expression upon the prisoner's face had changed. He seemed to be listening intently. Dorsky listened then, too, but could hear nothing; for by comparison with the hearing of Tarzan of the Apes Michael Dorsky was deaf. What Tarzan heard filled him with quiet satisfaction.

"Now," said Dorsky, "I have come to give you your last chance. Comrade Zveri has led two expeditions to Opar in search of the gold that we know is stored there. Both expeditions failed. It is well known that you know the location of the treasure vaults of Opar and can lead us to them. Agree that you will do this when Comrade Zveri returns, and not only will you not be harmed, but you will be released as quickly as Comrade Zveri feels that it would be safe to have you at liberty. Refuse and you die." He drew a long, slender stiletto from its sheath at his belt. "If you refuse to answer me, I shall accept that as evidence that you have not accepted my proposition." And as the ape-man maintained his stony silence, the Russian held the thin blade low before his eyes. "Think well, ape," he said, "and remember that when I slip this between your ribs there will be no sound. It will pierce your heart, and I shall leave it there until the blood has ceased to flow. Then I shall remove it and close the wound. Later in the day you will be found dead, and I shall tell the blacks that you died from the accidental gun-shot. Thus your friends will never learn the truth. You will not be avenged, and you will have died uselessly." He paused for a reply, his evil eyes glinting menacing into the cold, grey eyes of the ape-man.

The dagger was very near Tarzan's face now; and of a sudden, like a wild beast, he raised his body, and his jaws closed like a steel trap upon the wrist of the Russian. With a scream of pain, Dorsky drew back. The dagger dropped from his nerveless fingers. At the same instant Tarzan swung his legs around the feet of the would-be assassin; and as Dorsky rolled over on his back, he dragged Tarzan of the Apes on top of him.

The ape-man knew from the snapping of Dorsky's wrist bones between his teeth that the man's right hand was useless, and so he released it. Then to the Russian's horror, the ape-man's jaws sought his jugular as, from his throat, there rumbled the growl of a savage beast at bay.

Screaming for his men to come to his assistance, Dorsky tried to reach the revolver at his right hip with his left hand, but he soon saw that unless he could rid himself of Tarzan's body he would be unable to do so.

Already he heard his men running toward the tent, shouting among themselves, and then he heard exclamations of surprise and screams of terror. The next instant the tent vanished from above them, and Dorsky saw a huge bull elephant towering above him and his savage antagonist.
