"I am Tarzan of the Apes," replied the ape-man.

"And you carried Sublatus out of his palace above your head and mocked at his soldiers!" exclaimed the other. "By the ashes of my imperial father, Sublatus will see that you die the death."

Tarzan made no reply.

"They say you run through the trees like a monkey," said the other. "How then did you permit yourself to be recaptured?"

"It was done by treachery," replied Tarzan, "and the quickness with which they locked the shackles upon me. Without these," and he shook the manacles upon his wrists, "they could not hold me. But who are you and what did you do to get yourself in the dungeons of Caesar?"

"I am in the dungeon of no Caesar," replied the other. "This creature who sits upon the throne of Castra Sanguinarius is no Caesar."

"Who then is Caesar?" inquired Tarzan.

"Only the Emperors of the East are entitled to be called Caesar," replied the other.

"I take it that you are not of Castra Sanguinarius then," suggested the ape-man.

"No," replied the other, "I am from Castrum Mare."
