"Tell The Cid," said Tarzan, "that if we do not presently see a ship sail out alone to meet the fleet, we shall start dropping bombs upon the city."
Dorf led Lajo to a door in the cabin and flung it open. The man hesitated.
"Do not forget to jerk the ring," said Dorf, and at the same time he gave Lajo a violent push that sent him headlong through the doorway and a moment later the watchers in the cabin saw the white folds of the parachute streaming in the air. They saw it open and they knew that the message of Tarzan would be delivered to The Cid.
What went on in the city below we may not know, but presently a great crowd was seen to move from the palace down toward the river, where the ships were anchored, and a little later one of the ships weighed anchor and as it drifted slowly with the current its sails were set and presently it was moving directly out to sea toward the fleet from Sari.
The O-220 followed above it and Ja's flagship moved forward to meet it, and thus David Innes, Emperor of Pellucidar, was returned to his people.
As the Korsar ship turned back to port the dirigible dropped low above the flagship of the Sarian fleet and greetings were exchanged between David and his rescuers—men from another world whom he had never seen.
The Emperor was half starved and very thin and weak from his long period of confinement, but otherwise he had been unharmed, and great was the rejoicing aboard the ships of Sari as they turned back to cross the Korsar Az toward their own land.
Tarzan was afraid to accompany the fleet back to Sari for fear that their rapidly diminishing store of fuel would not be sufficient to complete the trip and carry them back to the outer world. He followed the fleet only long enough to obtain from David explicit directions for reaching the polar opening from the city of Korsar.
"We have another errand to fulfill first," said Jason to Tarzan. "We must return Thoar and Jana to Zoram."
"Yes," said the ape-man, "and drop these two Korsars off near their city. I have thought of all that and we shall have fuel enough for that purpose."
