"She belonged to Zoanthrohago," Kalfastoban explained to his friend, "but I doubt that he ever saw her, else he never would have parted with her for the paltry sum I paid."

"You will take her for your own woman and raise her to our class?" asked Hamadalban.

"No," replied Kalfastoban, "for then she would no longer be a slave and I could not sell her. Women are too expensive. I shall keep her for a time and then sell her while her value is still high. I should make a pretty profit from her."

Tarzan's fingers closed tightly, as though upon the throat of an enemy, and the right hand of Komodoflorensal crept to the hilt of his rapier.

A woman came from the quarters of Hamadalban and stood in the doorway.

"Two of the guards from the quarry are here with a green slave inquiring for Kalfastoban," she said.

"Send them in," directed the Vental.

A moment later the three entered—the slave was Caraftap.

"Ah!" exclaimed Kalfastoban, "my good slave, Caraftap; the best in the quarry. Why is he brought here?"

"He says that he has information of great value," replied one of the guard; "but he will divulge it to none but you. He has staked his life against the worth of his information and the Novand of the guard ordered him brought hither."
