"Komodoflorensal, you know best what avenues of escape should be the least beset by the dangers of discovery. Whether to go by way of Hamadalban's quarters or through the gallery they mentioned? These are questions I cannot answer to my own satisfaction; and look!" his eyes had been roving about the chamber, "there is an opening in the ceiling. Where might that lead?"

"It might lead almost anywhere, or nowhere at all," replied the Trohanadalmakusian. "Many chambers have such openings. Sometimes they lead into small lofts that are not connected with any other chamber; again they lead into secret chambers, or even into corridors upon another level."

There came a pounding upon the door leading into Hamadalban's quarters and a woman's voice called aloud: "Kalfastoban, open!" she cried. "There has come an ental from the quarry guard in search of Caraftap. The sentry at the entrance to the quarters of the slaves of Zoanthrohago has been found slain and they wish to question Caraftap, believing that there is a conspiracy among the slaves."

"We must go by the gallery," whispered Komodoflorensal, stepping quickly to the door leading thereto.

As he reached it someone laid a hand upon the latch from the opposite side and attempted to open the door, which was locked.

"Kalfastoban!" cried a voice from the gallery beyond. "Let us in! The slaves went not this way. Come, open quickly!"

Tarzan of the Apes glanced quickly about. Upon his face was a half-snarl, for once again was he the cornered beast. He measured the distance from the floor to the trap in the ceiling, and then with a little run he sprang lightly upward. He had forgotten to what extent the reduction of his weight had affected his agility. He had hoped to reach a handhold upon the upper edge of the opening, but instead he shot entirely through it, alighting upon his feet in a dark chamber. Turning he looked down at his friends below. Consternation was writ large upon the countenance of each; but at that he could not wonder. He was almost as much surprised himself.

"Is it too far for you to jump?" he asked.

"Too far!" they replied.

He swung, then, head downward through the opening, catching the edge of the trap in the hollow of his knees. At the gallery door the knocking was becoming insistent and now at that leading into the quarters of Hamadalban a man's voice had supplanted that of the woman. The fellow was demanding entrance, angrily.
