The cabin in which we found ourselves extended entirely across the ship, having port-holes on either side below the water line. No sooner were all below than a number of commands were given, in accordance with which the hatch was closed and secured, and the vessel commenced to vibrate to the rhythmic purr of its machinery.

"Where can we be going in such a tiny pool of water?" asked Phaidor.

"Not up," I replied, "for I noticed particularly that while the building is roofless it is covered with a strong metal grating."

"Then where?" she asked again.

"From the appearance of the craft I judge we are going down," I replied.

Phaidor shuddered. For such long ages have the waters of Barsoom's seas been a thing of tradition only that even this daughter of the therns, born as she had been within sight of Mars' only remaining sea, had the same terror of deep water as is a common attribute of all Martians.

Presently the sensation of sinking became very apparent. We were going down swiftly. Now we could hear the water rushing past the port-holes, and in the dim light that filtered through them to the water beyond the swirling eddies were plainly visible.

Phaidor grasped my arm.

"Save me!" she whispered. "Save me and your every wish shall be granted. Anything within the power of the Holy Therns to give will be yours. Phaidor-" she stumbled a little here, and then in a very low voice, "Phaidor already is yours."

I felt very sorry for the poor child, and placed my hand over hers where it rested on my arm. I presume my motive was misunderstood, for with a swift glance about the apartment to assure herself that we were alone, she threw both her arms about my neck and dragged my face down to hers.

The confession of love which the girl's fright had wrung from her touched me deeply; but it humiliated me as well, since I felt that in some thoughtless word or act I had given her reason to believe that I reciprocated her affection.

Never have I been much of a ladies' man, being more concerned with fighting and kindred arts which have ever seemed to me more befitting a man than mooning over a scented glove four sizes too small for him, or kissing a dead flower that has begun to smell like a cabbage. So I was quite at a loss as to what to do or say. A thousand times rather face the wild hordes of the dead sea bottoms than meet the eyes of this beautiful young girl and tell her the thing that I must tell her.

But there was nothing else to be done, and so I did it. Very clumsily too, I fear.

Gently I unclasped her hands from about my neck, and still holding them in mine I told her the story of my love for Dejah Thoris. That of all the women of two worlds that I had known and admired during my long life she alone had I loved.

The tale did not seem to please her. Like a tigress she sprang, panting, to her feet. Her beautiful face was distorted in an expression of horrible malevolence. Her eyes fairly blazed into mine.

"Dog," she hissed. "Dog of a blasphemer! Think you that Phaidor, daughter of Matai Shang, supplicates? She commands. What to her is your puny outer world passion for the vile creature you chose in your other life?

"Phaidor has glorified you with her love, and you have spurned her. Ten thousand unthinkably atrocious deaths could not atone for the affront that you have put upon me. The thing that you call Dejah Thoris shall die the most horrible of them all. You have sealed the warrant for her doom.

"And you! You shall be the meanest slave in the service of the goddess you have attempted to humiliate. Tortures and ignominies shall be heaped upon you until you grovel at my feet asking the boon of death.

"In my gracious generosity I shall at length grant your prayer, and from the high balcony of the Golden Cliffs I shall watch the great white apes tear you asunder."

She had it all fixed up. The whole lovely programme from start to finish. It amazed me to think that one so divinely beautiful could at the same time be so fiendishly vindictive. It occurred to me, however, that she had overlooked one little factor in her revenge, and so, without any intent to add to her discomfiture, but rather to permit her to rearrange her plans along more practical lines, I pointed to the nearest port-hole.

Evidently she had entirely forgotten her surroundings and her present circumstances, for a single glance at the dark, swirling waters without sent her crumpled upon a low bench, where with her face buried in her arms she sobbed more like a very unhappy little girl than a proud and all-powerful goddess.

Down, down we continued to sink until the heavy glass of the port-holes became noticeably warm from the heat of the water without. Evidently we were very far beneath the surface crust of Mars.

Presently our downward motion ceased, and I could hear the propellers swirling through the water at our stern and forcing us ahead at high speed. It was very dark down there, but the light from our port-holes, and the reflection from what must have been a powerful searchlight on the submarine's nose showed that we were forging through a narrow passage, rock-lined, and tube-like.

After a few minutes the propellers ceased their whirring. We came to a full stop, and then commenced to rise swiftly toward the surface. Soon the light from without increased and we came to a stop.

Xodar entered the cabin with his men.

"Come," he said, and we followed him through the hatchway which had been opened by one of the seamen.

We found ourselves in a small subterranean vault, in the centre of which was the pool in which lay our submarine, floating as we had first seen her with only her black back showing.

Around the edge of the pool was a level platform, and then the walls of the cave rose perpendicularly for a few feet to arch toward the centre of the low roof. The walls about the ledge were pierced with a number of entrances to dimly lighted passageways.

Toward one of these our captors led us, and after a short walk halted before a steel cage which lay at the bottom of a shaft rising above us as far as one could see.

The cage proved to be one of the common types of elevator cars that I had seen in other parts of Barsoom. They are operated by means of enormous magnets which are suspended at the top of the shaft. By an electrical device the volume of magnetism generated is regulated and the speed of the car varied.

In long stretches they move at a sickening speed, especially on the upward trip, since the small force of gravity inherent to Mars results in very little opposition to the powerful force above.

Scarcely had the door of the car closed behind us than we were slowing up to stop at the landing above, so rapid was our ascent of the long shaft.

When we emerged from the little building which houses the upper terminus of the elevator, we found ourselves in the midst of a veritable fairyland of beauty. The combined languages of Earth men hold no words to convey to the mind the gorgeous beauties of the scene.

One may speak of scarlet sward and ivory-stemmed trees decked with brilliant purple blooms; of winding walks paved with crushed rubies, with emerald, with turquoise, even with diamonds themselves; of a magnificent temple of burnished gold, hand-wrought with marvellous designs; but where are the words to describe the glorious colours that are unknown to earthly eyes? where the mind or the imagination that can grasp the gorgeous scintillations of unheard-of rays as they emanate from the thousand nameless jewels of Barsoom?

Even my eyes, for long years accustomed to the barbaric splendours of a Martian Jeddak's court, were amazed at the glory of the scene.

Phaidor's eyes were wide in amazement.
