"I guess this fellow knows which side his bread is buttered on," commented von Harben, with a grin.

Together Favonia, von Harben, Lepus, and Gabula stepped from the deserted building into the avenue. Approaching them they saw the head of a column of marching men; flaming torches lighted the scene until it was almost as bright as day.

"There is Cassius Hasta," exclaimed Mallius Lepus. "It is indeed he, but who are those with him?"

"They must be Sanguinarians," said Favonia. "But look, one of them is garbed like a barbarian, and see the strange, black warriors with their white plumes that are marching behind them."

"I have never seen the like in all my life," exclaimed Mallius Lepus.

"Neither have I," said von Harben, "but I am sure that I recognize them, for their fame is great and they answer the description that I have heard a thousand times."

"Who are they?" asked Favonia.

"The white giant is Tarzan of the Apes, and the black warriors are his Waziri fighting men."

At sight of the legionaries standing before the house, Cassius Hasta halted the column.

"Where is the centurion in command of these troops?" he demanded.
