Zutho stopped, bewildered. The others crowded about him.

"The Tarmangani spoke in the language of the great apes," said Zutho.

"I know him," said Go-yad. "He was king of the tribe when I was a young ape."

"It is, indeed, Whiteskin," said Gayat.

"Yes," said Tarzan, "I am Whiteskin. We are all prisoners here together. These Tarmangani are my enemies and yours. They wish us to fight, but we shall not."

"No," said Zutho, "we shall not fight against Tarzan."

"Good," said the ape-man, as they gathered close around him, sniffing that their noses might validate the testimony of their eyes.

"What has happened?" growled Sublatus. "Why do they not attack him?"

"He has cast a spell upon them," replied Caesar's guest.

The people looked on wonderingly. They heard the beasts and the man growling at one another. How could they guess that they were speaking together in their common language? They saw Tarzan turn and walk toward Caesar's loge, his bronzed skin brushing against the black coats of the savage beasts lumbering at his side. The ape-man and the apes halted below imperial Caesar. Tarzan's eyes ran quickly around the arena. The wall was lined with legionaries so not even Tarzan might pass these unscathed. He looked up at Sublatus.
