"I do not need riches," cackled Phor Tak. "Heigh-oo! Presently I shall own all the riches in the world."

"You will need help," I could hear the other man say in a pleading tone. "I can give you help; you shall have every ship of my great fleet."

That remark brought me upstanding-"every ship of my great fleet!" It could not be possible and yet-

Gently I tried the door. To my surprise it swung open revealing the interior of the room. Beneath a bright light stood Tul Axtar. Fifty feet from him Phor Tak was standing behind a bench upon which was mounted a disintegrating ray rifle, aimed full at Tul Axtar.

Where was Tavia? Where was Nur An? Perhaps this man alone knew where Tavia was and Phor Tak was about to destroy him. With a cry of warning I leaped into the room. Tul Axtar and Phor Tak looked at me quickly, surprise large upon their countenances.

"Heigh-oo!" screamed the old inventor. "So you have come back! Knave! Ingrate! Traitor! But you have come back only to die."

"Wait," I cried, raising my hand. "Let me speak."

"Silence!" screamed Phor Tak. "You shall see Tul Axtar die. I hated to kill him without someone to see-someone to witness his death agony. I shall have my revenge on him first and then on you."

"Stop!" I cried. His finger was already hovering over the button that would snatch Tul Axtar into oblivion, perhaps with the secret of the whereabouts of Tavia.

I drew my pistol. Phor Tak made a sudden motion with his hands and disappeared. He vanished as though turned to thin air by his own disintegrating rays, but I knew what had happened. I knew that he had thrown a mantle of invisibility around himself and I fired at the spot where he had last been visible.

At the same instant the floor opened beneath me and I shot into utter darkness.

I felt myself hurtling along a smooth surface which gradually became horizontal and an instant later I shot into a dimly lighted apartment, which I knew must be located in the pits beneath the palace.

I had clung to my pistol as I fell and now, as I arose to my feet, I thrust it back into its holster; at least I was not unarmed.

The dim light in the apartment, which was little better than no light at all, I discovered, came from a ventilator in the ceiling and that aside from the shaft that had conducted me to the cell, there was no other opening in the wall or ceiling or floor. The ventilator was about two feet in diameter and led straight up from the center of the ceiling to the roof of the building, several levels above. The lower end of the shaft was about two feet above my finger tips when I extended them high above my head. This avenue of escape, then, was useless, but, alas, how tantalizing. It was maddening to see daylight and an open avenue to the outer world just above me and be unable to reach it. I was glad that the sun had risen, throwing its quick light over the scene, for had I fallen here in utter darkness my plight would have seemed infinitely worse than now, and my first ancestor knew that it was bad enough. I turned my attention now to the chute through which I had descended and I found that I could ascend it quite a little distance, but presently it turned steeply upward and its smoothly polished walls were unscalable.

I returned to the pits. I must escape, but now, as my eyes became accustomed to the dim light, I saw strewn about the floor, that which snatched away my last hope and filled me with horror. Everywhere upon the stone flagging were heaps and mounds of human bones picked clean by gnawing rats. I shuddered as I contemplated the coming of night. How long before my bones, too, would be numbered among the rest?

The thought made me frantic, not for myself but for Tavia. I could not die. I must not die. I must live until I had found her.

Hastily I circled the room, searching for some clue to hope, but I found only rough-hewn stone set in soft mortar.

Soft mortar! With the realization, hope dawned anew. If I could remove a few of these blocks and pile them one on top of the other, I might easily reach the shaft that terminated in the ceiling above my head. Drawing my dagger I fell to work, scraping and scratching at the mortar about one of the stones in the nearest wall. It seemed slow work, but in reality I had loosened the stone in an incredibly short time. The mortar was poor stuff and crumbled away easily. As I drew the block out my first plan faded in the light of what I saw in front of me. Beyond the opening I saw a corridor at the foot of a spiral ramp leading upward, and from somewhere above, daylight was filtering down.

I knew that if I could remove three more of those stones before I was detected I could worm my body through the opening into the corridor beyond, and you may well believe that I worked rapidly.

One by one the blocks were loosened and removed and it was with a feeling of exultation that I slipped through into the corridor. Above me rose a spiral ramp. Where it led, I did not know, but at least it led out of the pits. Cautiously, and yet without any hesitation, I ascended. I must try to reach the laboratory before Phor Tak had slain Tul Axtar. This time I would make sure of the old inventor before I entered the room and I prayed to all my ancestors that I should be in time.

Doors, leading from the ramp to various levels of the palace, were all locked and I was forced to ascend to the roof. As it chanced the wing upon which I found myself was more or less detached, so that at first glance I could see no way whereby I could make my way from it to any of the adjoining roofs.

As I walked around the edge of the building hurriedly, looking for some means of descent to the roof below, I saw something one level below me that instantly charged my attention. It was a man's leg protruding from a window, as though he had thrown one limb across the sill. A moment later I saw an arm emerge, and the top of a man's head and his shoulders were visible as he leaned out. He reached down and up and I saw something appear directly beneath him that had not been there before, and at the same instant I caught a glimpse of a girl, lying a few feet further down, and then I saw the man slide over the sill quickly and drop down and disappear, and all that lay below me was the flagging of a courtyard.

But in that brief instant I knew precisely what I had seen. I had seen Tul Axtar raise the hatch of the Jhama. I had seen Tavia lying bound upon the floor of the ship beneath the hatch. I had seen Tul Axtar enter the interior of the craft and close the hatch above his head.

It takes a long while to tell it when compared with the time in which it actually transpired; nor was I so long in acting as I have been in telling.

As the hatch closed, I leaped.

Seventeen. I FIND A PRINCESS

It would be as unreasonable to aver that I fully visualized the outcome of my act as I leaped out into space with nothing visible between me and the flagstones of the courtyard forty feet below as it would be to assume that I acted solely upon unreasoning impulse. There are emergencies in which the mind functions with inconceivable celerity. Perceptions are received, judgments arrived at and reason operates to a definite conclusion all so swiftly that the three acts appear simultaneous. Thus must have been the process in this instance.

I knew where the narrow walkway upon the upper deck of the Jhama must lie in the seemingly empty space below me, for I had jumped almost the instant that the hatch had closed. Of course I know now, and I knew then, that it would have been a dangerous feat and difficult of achievement even had I been able to see the Jhama below me; yet as I look back upon it now there was nothing else that I could have done. It was my one, my last chance to save Tavia from a fate worse than death- it was perhaps my last opportunity ever to see her again. As I jumped then I should jump again under like conditions even though I knew that I should miss the Jhama, for now as then I know that I should rather die than lose Tavia; although then I did not know why, while now I do.
