"Who are you?" demanded Ja as the longboat came slowly about.
"We are friends," replied Tarzan.
"The Emperor of Pellucidar can have no friends upon the Korsar Az," replied Ja.
"If Abner Perry is with you, we can prove that you are wrong," replied Jason.
"Abner Perry is not with us," said Ja; "but what do you know of him?"
By this time the two boats were alongside and the bronzed Mezop warriors of Ja's crew were gazing down curiously upon the occupants of the boat.
"This is Jason Gridley," said Tarzan to Ja, indicating the American. "Perhaps you have heard Abner Perry speak of him. He organized an expedition in the outer world to come here to rescue David Innes from the dungeons of the Korsars."
The three Korsars of the longboat made Ja suspicious, but when a full explanation had been made and especially when he had examined the rifles of the Waziri, he became convinced of the truth of their statements and welcomed them warmly aboard his ship, about which were now gathered a considerable number of the armada. When word was passed among them that two of the strangers were friends from the outer world who had come to assist in the rescue of David Innes, a number of the captains of other ships came aboard Ja's flagship to greet Tarzan and Jason. Among these captains were Dacor the Strong One, brother of Dian the Beautiful, Empress of Pellucidar; Kolk, son of Goork, who is chief of the Thurians; and Tanar, son of Ghak, the Hairy One, King of Sari.
From these Tarzan and Jason learned that this fleet was on its way to effect the rescue of David. It had been building for a great while, so long that they had forgotten how many times they had eaten and slept since the first keel was laid, and then they had had to find a way into the Korsar Az from the Lural Az, where the ships were built upon the island of Anoroc.
"Far down the Sojar Az beyond the Land of Awful Shadow we found a passage that led to the Korsar Az. The Thurians had heard of it and while the fleet was building they sent warriors out to see if it was true and they found the passage and soon we shall be before the city of Korsar."
