A moment later a gun boomed from the rear turret of the O-220, marking the beginning of the first international salute of twenty-one guns that had ever reverberated beneath the eternal sun of Pellucidar, and when the significance of it was explained to Ja he returned the salute with the bow gun of his flagship. The dirigible dropped lower until it was within speaking distance of the flagship. "Are you all well aboard?" asked Tarzan. "Yes," came back the reassuring reply in Zuppner's booming tone. "Is Von Horst with you?" asked Jason. "No," replied Zuppner. "Then he alone is missing," said Jason sadly. "Can you drop a sling and take us aboard?" asked Tarzan. Zuppner maneuvered the dirigible to within fifty feet of the deck of Ja's flagship, a sling was lowered and one after another the members of the party were taken on board the O-220, the Waziri first and then Jana and Thoar, followed by Jason and Tarzan, the three Korsars being left prisoners with Ja with the understanding that they were to be treated humanely. Before Tarzan left the deck of the flagship he told Ja that if he would proceed toward Korsar, the dirigible would keep in touch with him and in the meantime they would be perfecting plans for the rescue of David Innes. As Thoar and Jana were hoisted aboard the O-220, they were filled with a boundless amazement. To them such a creation as the giant dirigible was inconceivable. As Jana expressed it afterward: "I knew that I was dreaming, but yet at the same time I knew that I could not dream about such a thing as this because no such thing existed." Jason introduced Jana and Thoar to Zuppner and Hines, but Lieutenant Dorf did not come to the cabin until after Tarzan had boarded the ship, and it was the latter who introduced them to Dorf. He presented Lieutenant Dorf to Jana and then, indicating Thoar, "This is Thoar, the brother of The Red Flower of Zoram." As those words broke upon the ears of Jason Gridley he reacted almost as to the shock of a physical blow. He was glad that no one chanced to be looking at him at the time and instantly he regained his composure, but it left him with a distinct feeling of injury. They had all known it and none of them had told him. He was almost angry at them until it occurred to him that they had all probably assumed that he had known it too, and yet try as he would he could not quite forgive Jana. But, really, what difference did it make, for, whether sister or mate of Thoar or another, he knew that The Red Flower of Zoram was not for him. She had made that definitely clear in her attitude toward him, which had convinced him even more definitely than had her bitter words. The reunited officers of the expedition had much to discuss and many reminiscences to narrate as the O-220 followed above the slowly moving fleet. It was a happy reunion, clouded only by the absence of Von Horst.
