"To wrest your daughter and the wife of this royal warrior from the clutches of these archfiends you have but to command the resources of a mighty nation, for all Kaol is at your disposal. What may be done? Say the word!"

"First," I suggested, "let us find those of your people who be responsible for the escape of Matai Shang and his followers. Without assistance on the part of the palace guard this thing could not have come to pass. Seek the guilty, and from them force an explanation of the manner of their going and the direction they have taken."

Before Kulan Tith could issue the commands that would initiate the investigation a handsome young officer stepped forward and addressed his jeddak.

"O Kulan Tith, Mightiest of Jeddaks," he said, "I alone be responsible for this grievous error. Last night it was I who commanded the palace guard. I was on duty in other parts of the palace during the audience of the early morning, and knew nothing of what transpired then, so that when the Father of Therns summoned me and explained that it was your wish that his party be hastened from the city because of the presence here of a deadly enemy who sought the Holy Hekkador's life I did only what a lifetime of training has taught me was the proper thing to do-I obeyed him whom I believed to be the ruler of us all, mightier even than thou, mightiest of jeddaks.

"Let the consequences and the punishment fall on me alone, for I alone am guilty. Those others of the palace guard who assisted in the flight did so under my instructions."

Kulan Tith looked first at me and then at Thuvan Dihn, as though to ask our judgment upon the man, but the error was so evidently excusable that neither of us had any mind to see the young officer suffer for a mistake that any might readily have made.

"How left they," asked Thuvan Dihn, "and what direction did they take?"

"They left as they came," replied the officer, "upon their own flier. For some time after they had departed I watched the vessel's lights, which vanished finally due north."

"Where north could Matai Shang find an asylum?" asked Thuvan Dihn of Kulan Tith.

For some moments the Jeddak of Kaol stood with bowed head, apparently deep in thought. Then a sudden light brightened his countenance.

"I have it!" he cried. "Only yesterday Matai Shang let drop a hint of his destination, telling me of a race of people unlike ourselves who dwell far to the north. They, he said, had always been known to the Holy Therns and were devout and faithful followers of the ancient cult. Among them would he find a perpetual haven of refuge, where no `lying heretics' might seek him out. It is there that Matai Shang has gone."

"And in all Kaol there be no flier wherein to follow," I cried.

"Nor nearer than Ptarth," replied Thuvan Dihn.

"Wait!" I exclaimed, "beyond the southern fringe of this great forest lies the wreck of the thern flier which brought me that far upon my way. If you will loan me men to fetch it, and artificers to assist me, I can repair it in two days, Kulan Tith."

I had been more than half suspicious of the seeming sincerity of the Kaolian jeddak's sudden apostasy, but the alacrity with which he embraced my suggestion, and the despatch with which a force of officers and men were placed at my disposal entirely removed the last vestige of my doubts.

Two days later the flier rested upon the top of the watchtower, ready to depart. Thuvan Dihn and Kulan Tith had offered me the entire resources of two nations-millions of fighting men were at my disposal; but my flier could hold but one other than myself and Woola.

As I stepped aboard her, Thuvan Dihn took his place beside me. I cast a look of questioning surprise upon him. He turned to the highest of his own officers who had accompanied him to Kaol.

"To you I entrust the return of my retinue to Ptarth," he said. "There my son rules ably in my absence. The Prince of Helium shall not go alone into the land of his enemies. I have spoken. Farewell!"

Straight toward the north, day and night, our destination compass led us after the fleeing flier upon which it had remained set since I first attuned it after leaving the thern fortress.

Early in the second night we noticed the air becoming perceptibly colder, and from the distance we had come from the equator were assured that we were rapidly approaching the north arctic region.

My knowledge of the efforts that had been made by countless expeditions to explore that unknown land bade me to caution, for never had flier returned who had passed to any considerable distance beyond the mighty ice-barrier that fringes the southern hem of the frigid zone.

What became of them none knew-only that they passed forever out of the sight of man into that grim and mysterious country of the pole.

The distance from the barrier to the pole was no more than a swift flier should cover in a few hours, and so it was assumed that some frightful catastrophe awaited those who reached the "forbidden land," as it had come to be called by the Martians of the outer world.

Thus it was that I went more slowly as we approached the barrier, for it was my intention to move cautiously by day over the ice-pack that I might discover, before I had run into a trap, if there really lay an inhabited country at the north pole, for there only could I imagine a spot where Matai Shang might feel secure from John Carter, Prince of Helium.

We were flying at a snail's pace but a few feet above the ground-literally feeling our way along through the darkness, for both moons had set, and the night was black with the clouds that are to be found only at Mars's two extremities.

Suddenly a towering wall of white rose directly in our path, and though I threw the helm hard over, and reversed our engine, I was too late to avoid collision. With a sickening crash we struck the high looming obstacle three-quarters on.

The flier reeled half over; the engine stopped; as one, the patched buoyancy tanks burst, and we plunged, headforemost, to the ground twenty feet beneath.

Fortunately none of us was injured, and when we had disentangled ourselves from the wreckage, and the lesser moon had burst again from below the horizon, we found that we were at the foot of a mighty ice-barrier, from which outcropped great patches of the granite hills which hold it from encroaching farther toward the south.

What fate! With the journey all but completed to be thus wrecked upon the wrong side of that precipitous and unscalable wall of rock and ice!

I looked at Thuvan Dihn. He but shook his head dejectedly.

The balance of the night we spent shivering in our inadequate sleeping silks and furs upon the snow that lies at the foot of the ice-barrier.

With daylight my battered spirits regained something of their accustomed hopefulness, though I must admit that there was little enough for them to feed upon.

"What shall we do?" asked Thuvan Dihn. "How may we pass that which is impassable?"

"First we must disprove its impassability," I replied. "Nor shall I admit that it is impassable before I have followed its entire circle and stand again upon this spot, defeated. The sooner we start, the better, for I see no other way, and it will take us more than a month to travel the weary, frigid miles that lie before us."

For five days of cold and suffering and privation we traversed the rough and frozen way which lies at the foot of the ice-barrier. Fierce, fur-bearing creatures attacked us by daylight and by dark. Never for a moment were we safe from the sudden charge of some huge demon of the north.

The apt was our most consistent and dangerous foe.

It is a huge, white-furred creature with six limbs, four of which, short and heavy, carry it swiftly over the snow and ice; while the other two, growing forward from its shoulders on either side of its long, powerful neck, terminate in white, hairless hands, with which it seizes and holds its prey.
