It was upon the verge of the land of the Kaols that I now knew myself to be, but in what direction to search for Dejah Thoris, or how far into the heart of the great forest I might have to penetrate I had not the faintest idea.

But not so Woola.

Scarcely had I disentangled him than he raised his head high in air and commenced circling about at the edge of the forest. Presently he halted, and, turning to see if I were following, set off straight into the maze of trees in the direction we had been going before Thurid's shot had put an end to our flier.

As best I could, I stumbled after him down a steep declivity beginning at the forest's edge.

Immense trees reared their mighty heads far above us, their broad fronds completely shutting off the slightest glimpse of the sky. It was easy to see why the Kaolians needed no navy; their cities, hidden in the midst of this towering forest, must be entirely invisible from above, nor could a landing be made by any but the smallest fliers, and then only with the greatest risk of accident.

How Thurid and Matai Shang were to land I could not imagine, though later I was to learn that to the level of the forest top there rises in each city of Kaol a slender watchtower which guards the Kaolians by day and by night against the secret approach of a hostile fleet. To one of these the hekkador of the Holy Therns had no difficulty in approaching, and by its means the party was safely lowered to the ground.

As Woola and I approached the bottom of the declivity the ground became soft and mushy, so that it was with the greatest difficulty that we made any headway whatever.

Slender purple grasses topped with red and yellow fern-like fronds grew rankly all about us to the height of several feet above my head.

Myriad creepers hung festooned in graceful loops from tree to tree, and among them were several varieties of the Martian "man-flower," whose blooms have eyes and hands with which to see and seize the insects which form their diet.

The repulsive calot tree was, too, much in evidence. It is a carnivorous plant of about the bigness of a large sage-brush such as dots our western plains. Each branch ends in a set of strong jaws, which have been known to drag down and devour large and formidable beasts of prey.

Both Woola and I had several narrow escapes from these greedy, arboreous monsters.

Occasional areas of firm sod gave us intervals of rest from the arduous labor of traversing this gorgeous, twilight swamp, and it was upon one of these that I finally decided to make camp for the night which my chronometer warned me would soon be upon us.

Many varieties of fruit grew in abundance about us; and as Martian calots are omnivorous, Woola had no difficulty in making a square meal after I had brought down the viands for him. Then, having eaten, too, I lay down with my back to that of my faithful hound, and dropped into a deep and dreamless sleep.

The forest was shrouded in impenetrable darkness when a low growl from Woola awakened me. All about us I could hear the stealthy movement of great, padded feet, and now and then the wicked gleam of green eyes upon us. Arising, I drew my long-sword and waited.

Suddenly a deep-toned, horrid roar burst from some savage throat almost at my side. What a fool I had been not to have found safer lodgings for myself and Woola among the branches of one of the countless trees that surrounded us!

By daylight it would have been comparatively easy to have hoisted Woola aloft in one manner or another, but now it was too late. There was nothing for it but to stand our ground and take our medicine, though, from the hideous racket which now assailed our ears, and for which that first roar had seemed to be the signal, I judged that we must be in the midst of hundreds, perhaps thousands, of the fierce, man-eating denizens of the Kaolian jungle.

All the balance of the night they kept up their infernal din, but why they did not attack us I could not guess, nor am I sure to this day, unless it is that none of them ever venture upon the patches of scarlet sward which dot the swamp.

When morning broke they were still there, walking about as in a circle, but always just beyond the edge of the sward. A more terrifying aggregation of fierce and blood-thirsty monsters it would be difficult to imagine.

Singly and in pairs they commenced wandering off into the jungle shortly after sunrise, and when the last of them had departed Woola and I resumed our journey.

Occasionally we caught glimpses of horrid beasts all during the day; but, fortunately, we were never far from a sward island, and when they saw us their pursuit always ended at the verge of the solid sod.

Toward noon we stumbled upon a well-constructed road running in the general direction we had been pursuing. Everything about this highway marked it as the work of skilled engineers, and I was confident, from the indications of antiquity which it bore, as well as from the very evident signs of its being still in everyday use, that it must lead to one of the principal cities of Kaol.

Just as we entered it from one side a huge monster emerged from the jungle upon the other, and at sight of us charged madly in our direction.

Imagine, if you can, a bald-faced hornet of your earthly experience grown to the size of a prize Hereford bull, and you will have some faint conception of the ferocious appearance and awesome formidability of the winged monster that bore down upon me.

Frightful jaws in front and mighty, poisoned sting behind made my relatively puny long-sword seem a pitiful weapon of defense indeed. Nor could I hope to escape the lightning-like movements or hide from those myriad facet eyes which covered three-fourths of the hideous head, permitting the creature to see in all directions at one and the same time.

Even my powerful and ferocious Woola was as helpless as a kitten before that frightful thing. But to flee were useless, even had it ever been to my liking to turn my back upon a danger; so I stood my ground, Woola snarling at my side, my only hope to die as I had always lived—fighting.

The creature was upon us now, and at the instant there seemed to me a single slight chance for victory. If I could but remove the terrible menace of certain death hidden in the poison sacs that fed the sting the struggle would be less unequal.

At the thought I called to Woola to leap upon the creature's head and hang there, and as his mighty jaws closed upon that fiendish face, and glistening fangs buried themselves in the bone and cartilage and lower part of one of the huge eyes, I dived beneath the great body as the creature rose, dragging Woola from the ground, that it might bring its sting beneath and pierce the body of the thing hanging to its head.

To put myself in the path of that poison-laden lance was to court instant death, but it was the only way; and as the thing shot lightning-like toward me I swung my long-sword in a terrific cut that severed the deadly member close to the gorgeously marked body.

Then, like a battering-ram, one of the powerful hind legs caught me full in the chest and hurled me, half stunned and wholly winded, clear across the broad highway and into the underbrush of the jungle that fringes it.

Fortunately, I passed between the boles of trees; had I struck one of them I should have been badly injured, if not killed, so swiftly had I been catapulted by that enormous hind leg.

Dazed though I was, I stumbled to my feet and staggered back to Woola's assistance, to find his savage antagonist circling ten feet above the ground, beating madly at the clinging calot with all six powerful legs.

Even during my sudden flight through the air I had not once released my grip upon my long-sword, and now I ran beneath the two battling monsters, jabbing the winged terror repeatedly with its sharp point.

The thing might easily have risen out of my reach, but evidently it knew as little concerning retreat in the face of danger as either Woola or I, for it dropped quickly toward me, and before I could escape had grasped my shoulder between its powerful jaws.

Time and again the now useless stub of its giant sting struck futilely against my body, but the blows alone were almost as effective as the kick of a horse; so that when I say futilely, I refer only to the natural function of the disabled member—eventually the thing would have hammered me to a pulp. Nor was it far from accomplishing this when an interruption occurred that put an end forever to its hostilities.

From where I hung a few feet above the road I could see along the highway a few hundred yards to where it turned toward the east, and just as I had about given up all hope of escaping the perilous position in which I now was I saw a red warrior come into view from around the bend.

He was mounted on a splendid thoat, one of the smaller species used by red men, and in his hand was a wondrous long, light lance.

His mount was walking sedately when I first perceived them, but the instant that the red man's eyes fell upon us a word to the thoat brought the animal at full charge down upon us. The long lance of the warrior dipped toward us, and as thoat and rider hurtled beneath, the point passed through the body of our antagonist.

With a convulsive shudder the thing stiffened, the jaws relaxed, dropping me to the ground, and then, careening once in mid air, the creature plunged headforemost to the road, full upon Woola, who still clung tenaciously to its gory head.

By the time I had regained my feet the red man had turned and ridden back to us. Woola, finding his enemy inert and lifeless, released his hold at my command and wriggled from beneath the body that had covered him, and together we faced the warrior looking down upon us.

I started to thank the stranger for his timely assistance, but he cut me off peremptorily.

"Who are you," he asked, "who dare enter the land of Kaol and hunt in the royal forest of the jeddak?"

Then, as he noted my white skin through the coating of grime and blood that covered me, his eyes went wide and in an altered tone he whispered: "Can it be that you are a Holy Thern?"

I might have deceived the fellow for a time, as I had deceived others, but I had cast away the yellow wig and the holy diadem in the presence of Matai Shang, and I knew that it would not be long ere my new acquaintance discovered that I was no thern at all.

"I am not a thern," I replied, and then, flinging caution to the winds, I said: "I am John Carter, Prince of Helium, whose name may not be entirely unknown to you."

If his eyes had gone wide when he thought that I was a Holy Thern, they fairly popped now that he knew that I was John Carter. I grasped my long-sword more firmly as I spoke the words which I was sure would precipitate an attack, but to my surprise they precipitated nothing of the kind.

"John Carter, Prince of Helium," he repeated slowly, as though he could not quite grasp the truth of the statement. "John Carter, the mightiest warrior of Barsoom!"

And then he dismounted and placed his hand upon my shoulder after the manner of most friendly greeting upon Mars.

"It is my duty, and it should be my pleasure, to kill you, John Carter," he said, "but always in my heart of hearts have I admired your prowess and believed in your sincerity the while I have questioned and disbelieved the therns and their religion.

"It would mean my instant death were my heresy to be suspected in the court of Kulan Tith, but if I may serve you, Prince, you have but to command Torkar Bar, Dwar of the Kaolian Road."

Truth and honesty were writ large upon the warrior's noble countenance, so that I could not but have trusted him, enemy though he should have been. His title of Captain of the Kaolian Road explained his timely presence in the heart of the savage forest, for every highway upon Barsoom is patrolled by doughty warriors of the noble class, nor is there any service more honorable than this lonely and dangerous duty in the less frequented sections of the domains of the red men of Barsoom.

"Torkar Bar has already placed a great debt of gratitude upon my shoulders," I replied, pointing to the carcass of the creature from whose heart he was dragging his long spear.

The red man smiled.

"It was fortunate that I came when I did," he said. "Only this poisoned spear pricking the very heart of a sith can kill it quickly enough to save its prey. In this section of Kaol we are all armed with a long sith spear, whose point is smeared with the poison of the creature it is intended to kill; no other virus acts so quickly upon the beast as its own.

"Look," he continued, drawing his dagger and making an incision in the carcass a foot above the root of the sting, from which he presently drew forth two sacs, each of which held fully a gallon of the deadly liquid.

"Thus we maintain our supply, though were it not for certain commercial uses to which the virus is put, it would scarcely be necessary to add to our present store, since the sith is almost extinct.

"Only occasionally do we now run upon one. Of old, however, Kaol was overrun with the frightful monsters that often came in herds of twenty or thirty, darting down from above into our cities and carrying away women, children, and even warriors."

As he spoke I had been wondering just how much I might safely tell this man of the mission which brought me to his land, but his next words anticipated the broaching of the subject on my part, and rendered me thankful that I had not spoken too soon.

"And now as to yourself, John Carter," he said, "I shall not ask your business here, nor do I wish to hear it. I have eyes and ears and ordinary intelligence, and yesterday morning I saw the party that came to the city of Kaol from the north in a small flier. But one thing I ask of you, and that is: the word of John Carter that he contemplates no overt act against either the nation of Kaol or its jeddak."

"You may have my word as to that, Torkar Bar," I replied.

"My way leads along the Kaolian road, away from the city of Kaol," he continued. "I have seen no one—John Carter least of all. Nor have you seen Torkar Bar, nor ever heard of him. You understand?"

"Perfectly," I replied.

He laid his hand upon my shoulder.

"This road leads directly into the city of Kaol," he said. "I wish you fortune," and vaulting to the back of his thoat he trotted away without even a backward glance.

It was after dark when Woola and I spied through the mighty forest the great wall which surrounds the city of Kaol.

We had traversed the entire way without mishap or adventure, and though the few we had met had eyed the great calot wonderingly, none had pierced the red pigment with which I had smoothly smeared every square inch of my body.

But to traverse the surrounding country, and to enter the guarded city of Kulan Tith, Jeddak of Kaol, were two very different things. No man enters a Martian city without giving a very detailed and satisfactory account of himself, nor did I delude myself with the belief that I could for a moment impose upon the acumen of the officers of the guard to whom I should be taken the moment I applied at any one of the gates.

My only hope seemed to lie in entering the city surreptitiously under cover of the darkness, and once in, trust to my own wits to hide myself in some crowded quarter where detection would be less liable to occur.

With this idea in view I circled the great wall, keeping within the fringe of the forest, which is cut away for a short distance from the wall all about the city, that no enemy may utilize the trees as a means of ingress.

Several times I attempted to scale the barrier at different points, but not even my earthly muscles could overcome that cleverly constructed rampart. To a height of thirty feet the face of the wall slanted outward, and then for almost an equal distance it was perpendicular, above which it slanted in again for some fifteen feet to the crest.

And smooth! Polished glass could not be more so. Finally I had to admit that at last I had discovered a Barsoomian fortification which I could not negotiate.

Discouraged, I withdrew into the forest beside a broad highway which entered the city from the east, and with Woola beside me lay down to sleep.



A HERO IN KAOL

It was daylight when I was awakened by the sound of stealthy movement near by.

As I opened my eyes Woola, too, moved and, coming up to his haunches, stared through the intervening brush toward the road, each hair upon his neck stiffly erect.

At first I could see nothing, but presently I caught a glimpse of a bit of smooth and glossy green moving among the scarlet and purple and yellow of the vegetation.

Motioning Woola to remain quietly where he was, I crept forward to investigate, and from behind the bole of a great tree I saw a long line of the hideous green warriors of the dead sea bottoms hiding in the dense jungle beside the road.

As far as I could see, the silent line of destruction and death stretched away from the city of Kaol. There could be but one explanation. The green men were expecting an exodus of a body of red troops from the nearest city gate, and they were lying there in ambush to leap upon them.

I owed no fealty to the Jeddak of Kaol, but he was of the same race of noble red men as my own princess, and I would not stand supinely by and see his warriors butchered by the cruel and heartless demons of the waste places of Barsoom.

Cautiously I retraced my steps to where I had left Woola, and warning him to silence, signaled him to follow me. Making a considerable detour to avoid the chance of falling into the hands of the green men, I came at last to the great wall.

A hundred yards to my right was the gate from which the troops were evidently expected to issue, but to reach it I must pass the flank of the green warriors within easy sight of them, and, fearing that my plan to warn the Kaolians might thus be thwarted, I decided upon hastening toward the left, where another gate a mile away would give me ingress to the city.

I knew that the word I brought would prove a splendid passport to Kaol, and I must admit that my caution was due more to my ardent desire to make my way into the city than to avoid a brush with the green men. As much as I enjoy a fight, I cannot always indulge myself, and just now I had more weighty matters to occupy my time than spilling the blood of strange warriors.

Could I but win beyond the city's wall, there might be opportunity in the confusion and excitement which were sure to follow my announcement of an invading force of green warriors to find my way within the palace of the jeddak, where I was sure Matai Shang and his party would be quartered.

But scarcely had I taken a hundred steps in the direction of the farther gate when the sound of marching troops, the clank of metal, and the squealing of thoats just within the city apprised me of the fact that the Kaolians were already moving toward the other gate.

There was no time to be lost. In another moment the gate would be opened and the head of the column pass out upon the death-bordered highway.

Turning back toward the fateful gate, I ran rapidly along the edge of the clearing, taking the ground in the mighty leaps that had first made me famous upon Barsoom. Thirty, fifty, a hundred feet at a bound are nothing for the muscles of an athletic Earth man upon Mars.

As I passed the flank of the waiting green men they saw my eyes turned upon them, and in an instant, knowing that all secrecy was at an end, those nearest me sprang to their feet in an effort to cut me off before I could reach the gate.

At the same instant the mighty portal swung wide and the head of the Kaolian column emerged. A dozen green warriors had succeeded in reaching a point between me and the gate, but they had but little idea who it was they had elected to detain.

I did not slacken my speed an iota as I dashed among them, and as they fell before my blade I could not but recall the happy memory of those other battles when Tars Tarkas, Jeddak of Thark, mightiest of Martian green men, had stood shoulder to shoulder with me through long, hot Martian days, as together we hewed down our enemies until the pile of corpses about us rose higher than a tall man's head.

When several pressed me too closely, there before the carved gateway of Kaol, I leaped above their heads, and fashioning my tactics after those of the hideous plant men of Dor, struck down upon my enemies' heads as I passed above them.

From the city the red warriors were rushing toward us, and from the jungle the savage horde of green men were coming to meet them. In a moment I was in the very center of as fierce and bloody a battle as I had ever passed through.

These Kaolians are most noble fighters, nor are the green men of the equator one whit less warlike than their cold, cruel cousins of the temperate zone. There were many times when either side might have withdrawn without dishonor and thus ended hostilities, but from the mad abandon with which each invariably renewed hostilities I soon came to believe that what need not have been more than a trifling skirmish would end only with the complete extermination of one force or the other.

With the joy of battle once roused within me, I took keen delight in the fray, and that my fighting was noted by the Kaolians was often evidenced by the shouts of applause directed at me.

If I sometimes seem to take too great pride in my fighting ability, it must be remembered that fighting is my vocation. If your vocation be shoeing horses, or painting pictures, and you can do one or the other better than your fellows, then you are a fool if you are not proud of your ability. And so I am very proud that upon two planets no greater fighter has ever lived than John Carter, Prince of Helium.

And I outdid myself that day to impress the fact upon the natives of Kaol, for I wished to win a way into their hearts—and their city. Nor was I to be disappointed in my desire.

All day we fought, until the road was red with blood and clogged with corpses. Back and forth along the slippery highway the tide of battle surged, but never once was the gateway to Kaol really in danger.

There were breathing spells when I had a chance to converse with the red men beside whom I fought, and once the jeddak, Kulan Tith himself, laid his hand upon my shoulder and asked my name.

"I am Dotar Sojat," I replied, recalling a name given me by the Tharks many years before, from the surnames of the first two of their warriors I had killed, which is the custom among them.

"You are a mighty warrior, Dotar Sojat," he replied, "and when this day is done I shall speak with you again in the great audience chamber."

And then the fight surged upon us once more and we were separated, but my heart's desire was attained, and it was with renewed vigor and a joyous soul that I laid about me with my long-sword until the last of the green men had had enough and had withdrawn toward their distant sea bottom.

Not until the battle was over did I learn why the red troops had sallied forth that day. It seemed that Kulan Tith was expecting a visit from a mighty jeddak of the north—a powerful and the only ally of the Kaolians, and it had been his wish to meet his guest a full day's journey from Kaol.

But now the march of the welcoming host was delayed until the following morning, when the troops again set out from Kaol. I had not been bidden to the presence of Kulan Tith after the battle, but he had sent an officer to find me and escort me to comfortable quarters in that part of the palace set aside for the officers of the royal guard.

There, with Woola, I had spent a comfortable night, and rose much refreshed after the arduous labors of the past few days. Woola had fought with me through the battle of the previous day, true to the instincts and training of a Martian war dog, great numbers of which are often to be found with the savage green hordes of the dead sea bottoms.

Neither of us had come through the conflict unscathed, but the marvelous, healing salves of Barsoom had sufficed, overnight, to make us as good as new.

I breakfasted with a number of the Kaolian officers, whom I found as courteous and delightful hosts as even the nobles of Helium, who are renowned for their ease of manners and excellence of breeding. The meal was scarcely concluded when a messenger arrived from Kulan Tith summoning me before him.

As I entered the royal presence the jeddak rose, and stepping from the dais which supported his magnificent throne, came forward to meet me—a mark of distinction that is seldom accorded to other than a visiting ruler.

"Kaor, Dotar Sojat!" he greeted me. "I have summoned you to receive the grateful thanks of the people of Kaol, for had it not been for your heroic bravery in daring fate to warn us of the ambuscade we must surely have fallen into the well-laid trap. Tell me more of yourself—from what country you come, and what errand brings you to the court of Kulan Tith."

"I am from Hastor," I said, for in truth I had a small palace in that southern city which lies within the far-flung dominions of the Heliumetic nation.

"My presence in the land of Kaol is partly due to accident, my flier being wrecked upon the southern fringe of your great forest. It was while seeking entrance to the city of Kaol that I discovered the green horde lying in wait for your troops."

If Kulan Tith wondered what business brought me in a flier to the very edge of his domain he was good enough not to press me further for an explanation, which I should indeed have had difficulty in rendering.

During my audience with the jeddak another party entered the chamber from behind me, so that I did not see their faces until Kulan Tith stepped past me to greet them, commanding me to follow and be presented.

As I turned toward them it was with difficulty that I controlled my features, for there, listening to Kulan Tith's eulogistic words concerning me, stood my arch-enemies, Matai Shang and Thurid.

"Holy Hekkador of the Holy Therns," the jeddak was saying, "shower thy blessings upon Dotar Sojat, the valorous stranger from distant Hastor, whose wondrous heroism and marvelous ferocity saved the day for Kaol yesterday."

Matai Shang stepped forward and laid his hand upon my shoulder. No slightest indication that he recognized me showed upon his countenance—my disguise was evidently complete.

He spoke kindly to me and then presented me to Thurid. The black, too, was evidently entirely deceived. Then Kulan Tith regaled them, much to my amusement, with details of my achievements upon the field of battle.

The thing that seemed to have impressed him most was my remarkable agility, and time and again he described the wondrous way in which I had leaped completely over an antagonist, cleaving his skull wide open with my long-sword as I passed above him.

I thought that I saw Thurid's eyes widen a bit during the narrative, and several times I surprised him gazing intently into my face through narrowed lids. Was he commencing to suspect? And then Kulan Tith told of the savage calot that fought beside me, and after that I saw suspicion in the eyes of Matai Shang—or did I but imagine it?

At the close of the audience Kulan Tith announced that he would have me accompany him upon the way to meet his royal guest, and as I departed with an officer who was to procure proper trappings and a suitable mount for me, both Matai Shang and Thurid seemed most sincere in professing their pleasure at having had an opportunity to know me. It was with a sigh of relief that I quitted the chamber, convinced that nothing more than a guilty conscience had prompted my belief that either of my enemies suspected my true identity.

A half-hour later I rode out of the city gate with the column that accompanied Kulan Tith upon the way to meet his friend and ally. Though my eyes and ears had been wide open during my audience with the jeddak and my various passages through the palace, I had seen or heard nothing of Dejah Thoris or Thuvia of Ptarth. That they must be somewhere within the great rambling edifice I was positive, and I should have given much to have found a way to remain behind during Kulan Tith's absence, that I might search for them.

Toward noon we came in touch with the head of the column we had set out to meet.

It was a gorgeous train that accompanied the visiting jeddak, and for miles it stretched along the wide, white road to Kaol. Mounted troops, their trappings of jewel and metal-incrusted leather glistening in the sunlight, formed the vanguard of the body, and then came a thousand gorgeous chariots drawn by huge zitidars.

These low, commodious wagons moved two abreast, and on either side of them marched solid ranks of mounted warriors, for in the chariots were the women and children of the royal court. Upon the back of each monster zitidar rode a Martian youth, and the whole scene carried me back to my first days upon Barsoom, now twenty-two years in the past, when I had first beheld the gorgeous spectacle of a caravan of the green horde of Tharks.

Never before today had I seen zitidars in the service of red men. These brutes are huge mastodonian animals that tower to an immense height even beside the giant green men and their giant thoats; but when compared to the relatively small red man and his breed of thoats they assume Brobdingnagian proportions that are truly appalling.

The beasts were hung with jeweled trappings and saddlepads of gay silk, embroidered in fanciful designs with strings of diamonds, pearls, rubies, emeralds, and the countless unnamed jewels of Mars, while from each chariot rose a dozen standards from which streamers, flags, and pennons fluttered in the breeze.

Just in front of the chariots the visiting jeddak rode alone upon a pure white thoat—another unusual sight upon Barsoom—and after them came interminable ranks of mounted spearmen, riflemen, and swordsmen. It was indeed a most imposing sight.

Except for the clanking of accouterments and the occasional squeal of an angry thoat or the low guttural of a zitidar, the passage of the cavalcade was almost noiseless, for neither thoat nor zitidar is a hoofed animal, and the broad tires of the chariots are of an elastic composition, which gives forth no sound.

Now and then the gay laughter of a woman or the chatter of children could be heard, for the red Martians are a social, pleasure-loving people—in direct antithesis to the cold and morbid race of green men.

The forms and ceremonials connected with the meeting of the two jeddaks consumed an hour, and then we turned and retraced our way toward the city of Kaol, which the head of the column reached just before dark, though it must have been nearly morning before the rear guard passed through the gateway.

Fortunately, I was well up toward the head of the column, and after the great banquet, which I attended with the officers of the royal guard, I was free to seek repose. There was so much activity and bustle about the palace all during the night with the constant arrival of the noble officers of the visiting jeddak's retinue that I dared not attempt to prosecute a search for Dejah Thoris, and so, as soon as it was seemly for me to do so, I returned to my quarters.

As I passed along the corridors between the banquet hall and the apartments that had been allotted me, I had a sudden feeling that I was under surveillance, and, turning quickly in my tracks, caught a glimpse of a figure which darted into an open doorway the instant I wheeled about.

Though I ran quickly back to the spot where the shadower had disappeared I could find no trace of him, yet in the brief glimpse that I had caught I could have sworn that I had seen a white face surmounted by a mass of yellow hair.

The incident gave me considerable food for speculation, since if I were right in the conclusion induced by the cursory glimpse I had had of the spy, then Matai Shang and Thurid must suspect my identity, and if that were true not even the service I had rendered Kulan Tith could save me from his religious fanaticism.

But never did vague conjecture or fruitless fears for the future lie with sufficient weight upon my mind to keep me from my rest, and so tonight I threw myself upon my sleeping silks and furs and passed at once into dreamless slumber.

Calots are not permitted within the walls of the palace proper, and so I had had to relegate poor Woola to quarters in the stables where the royal thoats are kept. He had comfortable, even luxurious apartments, but I would have given much to have had him with me; and if he had been, the thing which happened that night would not have come to pass.

I could not have slept over a quarter of an hour when I was suddenly awakened by the passing of some cold and clammy thing across my forehead. Instantly I sprang to my feet, clutching in the direction I thought the presence lay. For an instant my hand touched against human flesh, and then, as I lunged headforemost through the darkness to seize my nocturnal visitor, my foot became entangled in my sleeping silks and I fell sprawling to the floor.

By the time I had resumed my feet and found the button which controlled the light my caller had disappeared. Careful search of the room revealed nothing to explain either the identity or business of the person who had thus secretly sought me in the dead of night.

That the purpose might be theft I could not believe, since thieves are practically unknown upon Barsoom. Assassination, however, is rampant, but even this could not have been the motive of my stealthy friend, for he might easily have killed me had he desired.

I had about given up fruitless conjecture and was on the point of returning to sleep when a dozen Kaolian guardsmen entered my apartment. The officer in charge was one of my genial hosts of the morning, but now upon his face was no sign of friendship.

"Kulan Tith commands your presence before him," he said. "Come!"



NEW ALLIES

Surrounded by guardsmen I marched back along the corridors of the palace of Kulan Tith, Jeddak of Kaol, to the great audience chamber in the center of the massive structure.

As I entered the brilliantly lighted apartment, filled with the nobles of Kaol and the officers of the visiting jeddak, all eyes were turned upon me. Upon the great dais at the end of the chamber stood three thrones, upon which sat Kulan Tith and his two guests, Matai Shang, and the visiting jeddak.

Up the broad center aisle we marched beneath deadly silence, and at the foot of the thrones we halted.

"Prefer thy charge," said Kulan Tith, turning to one who stood among the nobles at his right; and then Thurid, the black dator of the First Born, stepped forward and faced me.

"Most noble Jeddak," he said, addressing Kulan Tith, "from the first I suspected this stranger within thy palace. Your description of his fiendish prowess tallied with that of the arch-enemy of truth upon Barsoom.

"But that there might be no mistake I despatched a priest of your own holy cult to make the test that should pierce his disguise and reveal the truth. Behold the result!" and Thurid pointed a rigid finger at my forehead.

All eyes followed the direction of that accusing digit—I alone seemed at a loss to guess what fatal sign rested upon my brow.

The officer beside me guessed my perplexity; and as the brows of Kulan Tith darkened in a menacing scowl as his eyes rested upon me, the noble drew a small mirror from his pocket-pouch and held it before my face.

One glance at the reflection it gave back to me was sufficient.

From my forehead the hand of the sneaking thern had reached out through the concealing darkness of my bed-chamber and wiped away a patch of the disguising red pigment as broad as my palm. Beneath showed the tanned texture of my own white skin.

For a moment Thurid ceased speaking, to enhance, I suspect, the dramatic effect of his disclosure. Then he resumed.

"Here, O Kulan Tith," he cried, "is he who has desecrated the temples of the Gods of Mars, who has violated the persons of the Holy Therns themselves and turned a world against its age-old religion. Before you, in your power, Jeddak of Kaol, Defender of the Holies, stands John Carter, Prince of Helium!"

Kulan Tith looked toward Matai Shang as though for corroboration of these charges. The Holy Thern nodded his head.

"It is indeed the arch-blasphemer," he said. "Even now he has followed me to the very heart of thy palace, Kulan Tith, for the sole purpose of assassinating me. He—"

"He lies!" I cried. "Kulan Tith, listen that you may know the truth. Listen while I tell you why John Carter has followed Matai Shang to the heart of thy palace. Listen to me as well as to them, and then judge if my acts be not more in accord with true Barsoomian chivalry and honor than those of these revengeful devotees of the spurious creeds from whose cruel bonds I have freed your planet."

"Silence!" roared the jeddak, leaping to his feet and laying his hand upon the hilt of his sword. "Silence, blasphemer! Kulan Tith need not permit the air of his audience chamber to be defiled by the heresies that issue from your polluted throat to judge you.

"You stand already self-condemned. It but remains to determine the manner of your death. Even the service that you rendered the arms of Kaol shall avail you naught; it was but a base subterfuge whereby you might win your way into my favor and reach the side of this holy man whose life you craved. To the pits with him!" he concluded, addressing the officer of my guard.

Here was a pretty pass, indeed! What chance had I against a whole nation? What hope for me of mercy at the hands of the fanatical Kulan Tith with such advisers as Matai Shang and Thurid. The black grinned malevolently in my face.

"You shall not escape this time, Earth man," he taunted.

The guards closed toward me. A red haze blurred my vision. The fighting blood of my Virginian sires coursed hot through my veins. The lust of battle in all its mad fury was upon me.

With a leap I was beside Thurid, and ere the devilish smirk had faded from his handsome face I had caught him full upon the mouth with my clenched fist; and as the good, old American blow landed, the black dator shot back a dozen feet, to crumple in a heap at the foot of Kulan Tith's throne, spitting blood and teeth from his hurt mouth.

Then I drew my sword and swung round, on guard, to face a nation.

In an instant the guardsmen were upon me, but before a blow had been struck a mighty voice rose above the din of shouting warriors, and a giant figure leaped from the dais beside Kulan Tith and, with drawn long-sword, threw himself between me and my adversaries.

It was the visiting jeddak.

"Hold!" he cried. "If you value my friendship, Kulan Tith, and the age-old peace that has existed between our peoples, call off your swordsmen; for wherever or against whomsoever fights John Carter, Prince of Helium, there beside him and to the death fights Thuvan Dihn, Jeddak of Ptarth."

The shouting ceased and the menacing points were lowered as a thousand eyes turned first toward Thuvan Dihn in surprise and then toward Kulan Tith in question. At first the Jeddak of Kaol went white in rage, but before he spoke he had mastered himself, so that his tone was calm and even as befitted intercourse between two great jeddaks.

"Thuvan Dihn," he said slowly, "must have great provocation thus to desecrate the ancient customs which inspire the deportment of a guest within the palace of his host. Lest I, too, should forget myself as has my royal friend, I should prefer to remain silent until the Jeddak of Ptarth has won from me applause for his action by relating the causes which provoked it."

I could see that the Jeddak of Ptarth was of half a mind to throw his metal in Kulan Tith's face, but he controlled himself even as well as had his host.

"None knows better than Thuvan Dihn," he said, "the laws which govern the acts of men in the domains of their neighbors; but Thuvan Dihn owes allegiance to a higher law than these—the law of gratitude. Nor to any man upon Barsoom does he owe a greater debt of gratitude than to John Carter, Prince of Helium.

"Years ago, Kulan Tith," he continued, "upon the occasion of your last visit to me, you were greatly taken with the charms and graces of my only daughter, Thuvia. You saw how I adored her, and later you learned that, inspired by some unfathomable whim, she had taken the last, long, voluntary pilgrimage upon the cold bosom of the mysterious Iss, leaving me desolate.

"Some months ago I first heard of the expedition which John Carter had led against Issus and the Holy Therns. Faint rumors of the atrocities reported to have been committed by the therns upon those who for countless ages have floated down the mighty Iss came to my ears.

"I heard that thousands of prisoners had been released, few of whom dared to return to their own countries owing to the mandate of terrible death which rests against all who return from the Valley Dor.

"For a time I could not believe the heresies which I heard, and I prayed that my daughter Thuvia might have died before she ever committed the sacrilege of returning to the outer world. But then my father's love asserted itself, and I vowed that I would prefer eternal damnation to further separation from her if she could be found.

"So I sent emissaries to Helium, and to the court of Xodar, Jeddak of the First Born, and to him who now rules those of the thern nation that have renounced their religion; and from each and all I heard the same story of unspeakable cruelties and atrocities perpetrated upon the poor defenseless victims of their religion by the Holy Therns.

"Many there were who had seen or known my daughter, and from therns who had been close to Matai Shang I learned of the indignities that he personally heaped upon her; and I was glad when I came here to find that Matai Shang was also your guest, for I should have sought him out had it taken a lifetime.

"More, too, I heard, and that of the chivalrous kindness that John Carter had accorded my daughter. They told me how he fought for her and rescued her, and how he spurned escape from the savage Warhoons of the south, sending her to safety upon his own thoat and remaining upon foot to meet the green warriors.

"Can you wonder, Kulan Tith, that I am willing to jeopardize my life, the peace of my nation, or even your friendship, which I prize more than aught else, to champion the Prince of Helium?"

For a moment Kulan Tith was silent. I could see by the expression of his face that he was sore perplexed. Then he spoke.

"Thuvan Dihn," he said, and his tone was friendly though sad, "who am I to judge my fellow-man? In my eyes the Father of Therns is still holy, and the religion which he teaches the only true religion, but were I faced by the same problem that has vexed you I doubt not that I should feel and act precisely as you have.

"In so far as the Prince of Helium is concerned I may act, but between you and Matai Shang my only office can be one of conciliation. The Prince of Helium shall be escorted in safety to the boundary of my domain ere the sun has set again, where he shall be free to go whither he will; but upon pain of death must he never again enter the land of Kaol.

"If there be a quarrel between you and the Father of Therns, I need not ask that the settlement of it be deferred until both have passed beyond the limits of my power. Are you satisfied, Thuvan Dihn?"

The Jeddak of Ptarth nodded his assent, but the ugly scowl that he bent upon Matai Shang harbored ill for that pasty-faced godling.

"The Prince of Helium is far from satisfied," I cried, breaking rudely in upon the beginnings of peace, for I had no stomach for peace at the price that had been named.

"I have escaped death in a dozen forms to follow Matai Shang and overtake him, and I do not intend to be led, like a decrepit thoat to the slaughter, from the goal that I have won by the prowess of my sword arm and the might of my muscles.

"Nor will Thuvan Dihn, Jeddak of Ptarth, be satisfied when he has heard me through. Do you know why I have followed Matai Shang and Thurid, the black dator, from the forests of the Valley Dor across half a world through almost insurmountable difficulties?

"Think you that John Carter, Prince of Helium, would stoop to assassination? Can Kulan Tith be such a fool as to believe that lie, whispered in his ear by the Holy Thern or Dator Thurid?

"I do not follow Matai Shang to kill him, though the God of mine own planet knows that my hands itch to be at his throat. I follow him, Thuvan Dihn, because with him are two prisoners—my wife, Dejah Thoris, Princess of Helium, and your daughter, Thuvia of Ptarth.

"Now think you that I shall permit myself to be led beyond the walls of Kaol unless the mother of my son accompanies me, and thy daughter be restored?"

Thuvan Dihn turned upon Kulan Tith. Rage flamed in his keen eyes; but by the masterfulness of his self-control he kept his tones level as he spoke.

"Knew you this thing, Kulan Tith?" he asked. "Knew you that my daughter lay a prisoner in your palace?"

"He could not know it," interrupted Matai Shang, white with what I am sure was more fear than rage. "He could not know it, for it is a lie."

I would have had his life for that upon the spot, but even as I sprang toward him Thuvan Dihn laid a heavy hand upon my shoulder.

"Wait," he said to me, and then to Kulan Tith. "It is not a lie. This much have I learned of the Prince of Helium—he does not lie. Answer me, Kulan Tith—I have asked you a question."

"Three women came with the Father of Therns," replied Kulan Tith. "Phaidor, his daughter, and two who were reported to be her slaves. If these be Thuvia of Ptarth and Dejah Thoris of Helium I did not know it—I have seen neither. But if they be, then shall they be returned to you on the morrow."

As he spoke he looked straight at Matai Shang, not as a devotee should look at a high priest, but as a ruler of men looks at one to whom he issues a command.

It must have been plain to the Father of Therns, as it was to me, that the recent disclosures of his true character had done much already to weaken the faith of Kulan Tith, and that it would require but little more to turn the powerful jeddak into an avowed enemy; but so strong are the seeds of superstition that even the great Kaolian still hesitated to cut the final strand that bound him to his ancient religion.

Matai Shang was wise enough to seem to accept the mandate of his follower, and promised to bring the two slave women to the audience chamber on the morrow.

"It is almost morning now," he said, "and I should dislike to break in upon the slumber of my daughter, or I would have them fetched at once that you might see that the Prince of Helium is mistaken," and he emphasized the last word in an effort to affront me so subtlety that I could not take open offense.

I was about to object to any delay, and demand that the Princess of Helium be brought to me forthwith, when Thuvan Dihn made such insistence seem unnecessary.

"I should like to see my daughter at once," he said, "but if Kulan Tith will give me his assurance that none will be permitted to leave the palace this night, and that no harm shall befall either Dejah Thoris or Thuvia of Ptarth between now and the moment they are brought into our presence in this chamber at daylight I shall not insist."

"None shall leave the palace tonight," replied the Jeddak of Kaol, "and Matai Shang will give us assurance that no harm will come to the two women?"

The thern assented with a nod. A few moments later Kulan Tith indicated that the audience was at an end, and at Thuvan Dihn's invitation I accompanied the Jeddak of Ptarth to his own apartments, where we sat until daylight, while he listened to the account of my experiences upon his planet and to all that had befallen his daughter during the time that we had been together.

I found the father of Thuvia a man after my own heart, and that night saw the beginning of a friendship which has grown until it is second only to that which obtains between Tars Tarkas, the green Jeddak of Thark, and myself.

The first burst of Mars's sudden dawn brought messengers from Kulan Tith, summoning us to the audience chamber where Thuvan Dihn was to receive his daughter after years of separation, and I was to be reunited with the glorious daughter of Helium after an almost unbroken separation of twelve years.

My heart pounded within my bosom until I looked about me in embarrassment, so sure was I that all within the room must hear. My arms ached to enfold once more the divine form of her whose eternal youth and undying beauty were but outward manifestations of a perfect soul.

At last the messenger despatched to fetch Matai Shang returned. I craned my neck to catch the first glimpse of those who should be following, but the messenger was alone.

Halting before the throne he addressed his jeddak in a voice that was plainly audible to all within the chamber.

"O Kulan Tith, Mightiest of Jeddaks," he cried, after the fashion of the court, "your messenger returns alone, for when he reached the apartments of the Father of Therns he found them empty, as were those occupied by his suite."

Kulan Tith went white.

A low groan burst from the lips of Thuvan Dihn who stood next me, not having ascended the throne which awaited him beside his host. For a moment the silence of death reigned in the great audience chamber of Kulan Tith, Jeddak of Kaol. It was he who broke the spell.

Rising from his throne he stepped down from the dais to the side of Thuvan Dihn. Tears dimmed his eyes as he placed both his hands upon the shoulders of his friend.

"O Thuvan Dihn," he cried, "that this should have happened in the palace of thy best friend! With my own hands would I have wrung the neck of Matai Shang had I guessed what was in his foul heart. Last night my life-long faith was weakened—this morning it has been shattered; but too late, too late.

"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!"



THROUGH THE CARRION CAVES

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.

Its head and mouth are more similar in appearance to those of a hippopotamus than to any other earthly animal, except that from the sides of the lower jawbone two mighty horns curve slightly downward toward the front.

Its two huge eyes inspired my greatest curiosity. They extend in two vast, oval patches from the center of the top of the cranium down either side of the head to below the roots of the horns, so that these weapons really grow out from the lower part of the eyes, which are composed of several thousand ocelli each.

This eye structure seemed remarkable in a beast whose haunts were upon a glaring field of ice and snow, and though I found upon minute examination of several that we killed that each ocellus is furnished with its own lid, and that the animal can at will close as many of the facets of his huge eyes as he chooses, yet I was positive that nature had thus equipped him because much of his life was to be spent in dark, subterranean recesses.

Shortly after this we came upon the hugest apt that we had seen. The creature stood fully eight feet at the shoulder, and was so sleek and clean and glossy that I could have sworn that he had but recently been groomed.

He stood head-on eyeing us as we approached him, for we had found it a waste of time to attempt to escape the perpetual bestial rage which seems to possess these demon creatures, who rove the dismal north attacking every living thing that comes within the scope of their far-seeing eyes.

Even when their bellies are full and they can eat no more, they kill purely for the pleasure which they derive from taking life, and so when this particular apt failed to charge us, and instead wheeled and trotted away as we neared him, I should have been greatly surprised had I not chanced to glimpse the sheen of a golden collar about its neck.

Thuvan Dihn saw it, too, and it carried the same message of hope to us both. Only man could have placed that collar there, and as no race of Martians of which we knew aught ever had attempted to domesticate the ferocious apt, he must belong to a people of the north of whose very existence we were ignorant—possibly to the fabled yellow men of Barsoom; that once powerful race which was supposed to be extinct, though sometimes, by theorists, thought still to exist in the frozen north.

Simultaneously we started upon the trail of the great beast. Woola was quickly made to understand our desires, so that it was unnecessary to attempt to keep in sight of the animal whose swift flight over the rough ground soon put him beyond our vision.

For the better part of two hours the trail paralleled the barrier, and then suddenly turned toward it through the roughest and seemingly most impassable country I ever had beheld.

Enormous granite boulders blocked the way on every hand; deep rifts in the ice threatened to engulf us at the least misstep; and from the north a slight breeze wafted to our nostrils an unspeakable stench that almost choked us.

For another two hours we were occupied in traversing a few hundred yards to the foot of the barrier.

Then, turning about the corner of a wall-like outcropping of granite, we came upon a smooth area of two or three acres before the base of the towering pile of ice and rock that had baffled us for days, and before us beheld the dark and cavernous mouth of a cave.

From this repelling portal the horrid stench was emanating, and as Thuvan Dihn espied the place he halted with an exclamation of profound astonishment.

"By all my ancestors!" he ejaculated. "That I should have lived to witness the reality of the fabled Carrion Caves! If these indeed be they, we have found a way beyond the ice-barrier.

"The ancient chronicles of the first historians of Barsoom—so ancient that we have for ages considered them mythology—record the passing of the yellow men from the ravages of the green hordes that overran Barsoom as the drying up of the great oceans drove the dominant races from their strongholds.

"They tell of the wanderings of the remnants of this once powerful race, harassed at every step, until at last they found a way through the ice-barrier of the north to a fertile valley at the pole.

"At the opening to the subterranean passage that led to their haven of refuge a mighty battle was fought in which the yellow men were victorious, and within the caves that gave ingress to their new home they piled the bodies of the dead, both yellow and green, that the stench might warn away their enemies from further pursuit.

"And ever since that long-gone day have the dead of this fabled land been carried to the Carrion Caves, that in death and decay they might serve their country and warn away invading enemies. Here, too, is brought, so the fable runs, all the waste stuff of the nation—everything that is subject to rot, and that can add to the foul stench that assails our nostrils.

"And death lurks at every step among rotting dead, for here the fierce apts lair, adding to the putrid accumulation with the fragments of their own prey which they cannot devour. It is a horrid avenue to our goal, but it is the only one."

"You are sure, then, that we have found the way to the land of the yellow men?" I cried.

"As sure as may be," he replied; "having only ancient legend to support my belief. But see how closely, so far, each detail tallies with the world-old story of the hegira of the yellow race. Yes, I am sure that we have discovered the way to their ancient hiding place."

"If it be true, and let us pray that such may be the case," I said, "then here may we solve the mystery of the disappearance of Tardos Mors, Jeddak of Helium, and Mors Kajak, his son, for no other spot upon Barsoom has remained unexplored by the many expeditions and the countless spies that have been searching for them for nearly two years. The last word that came from them was that they sought Carthoris, my own brave son, beyond the ice-barrier."

As we talked we had been approaching the entrance to the cave, and as we crossed the threshold I ceased to wonder that the ancient green enemies of the yellow men had been halted by the horrors of that awful way.

The bones of dead men lay man high upon the broad floor of the first cave, and over all was a putrid mush of decaying flesh, through which the apts had beaten a hideous trail toward the entrance to the second cave beyond.

The roof of this first apartment was low, like all that we traversed subsequently, so that the foul odors were confined and condensed to such an extent that they seemed to possess tangible substance. One was almost tempted to draw his short-sword and hew his way through in search of pure air beyond.

"Can man breathe this polluted air and live?" asked Thuvan Dihn, choking.

"Not for long, I imagine," I replied; "so let us make haste. I will go first, and you bring up the rear, with Woola between. Come," and with the words I dashed forward, across the fetid mass of putrefaction.

It was not until we had passed through seven caves of different sizes and varying but little in the power and quality of their stenches that we met with any physical opposition. Then, within the eighth cave, we came upon a lair of apts.

A full score of the mighty beasts were disposed about the chamber. Some were sleeping, while others tore at the fresh-killed carcasses of new-brought prey, or fought among themselves in their love-making.

Here in the dim light of their subterranean home the value of their great eyes was apparent, for these inner caves are shrouded in perpetual gloom that is but little less than utter darkness.

To attempt to pass through the midst of that fierce herd seemed, even to me, the height of folly, and so I proposed to Thuvan Dihn that he return to the outer world with Woola, that the two might find their way to civilization and come again with a sufficient force to overcome not only the apts, but any further obstacles that might lie between us and our goal.

"In the meantime," I continued, "I may discover some means of winning my way alone to the land of the yellow men, but if I am unsuccessful one life only will have been sacrificed. Should we all go on and perish, there will be none to guide a succoring party to Dejah Thoris and your daughter."

"I shall not return and leave you here alone, John Carter," replied Thuvan Dihn. "Whether you go on to victory or death, the Jeddak of Ptarth remains at your side. I have spoken."

I knew from his tone that it were useless to attempt to argue the question, and so I compromised by sending Woola back with a hastily penned note enclosed in a small metal case and fastened about his neck. I commanded the faithful creature to seek Carthoris at Helium, and though half a world and countless dangers lay between I knew that if the thing could be done Woola would do it.

Equipped as he was by nature with marvelous speed and endurance, and with frightful ferocity that made him a match for any single enemy of the way, his keen intelligence and wondrous instinct should easily furnish all else that was needed for the successful accomplishment of his mission.

It was with evident reluctance that the great beast turned to leave me in compliance with my command, and ere he had gone I could not resist the inclination to throw my arms about his great neck in a parting hug. He rubbed his cheek against mine in a final caress, and a moment later was speeding through the Carrion Caves toward the outer world.

In my note to Carthoris I had given explicit directions for locating the Carrion Caves, impressing upon him the necessity for making entrance to the country beyond through this avenue, and not to attempt under any circumstances to cross the ice-barrier with a fleet. I told him that what lay beyond the eighth cave I could not even guess; but I was sure that somewhere upon the other side of the ice-barrier his mother lay in the power of Matai Shang, and that possibly his grandfather and great-grandfather as well, if they lived.

Further, I advised him to call upon Kulan Tith and the son of Thuvan Dihn for warriors and ships that the expedition might be sufficiently strong to insure success at the first blow.

"And," I concluded, "if there be time bring Tars Tarkas with you, for if I live until you reach me I can think of few greater pleasures than to fight once more, shoulder to shoulder, with my old friend."

When Woola had left us Thuvan Dihn and I, hiding in the seventh cave, discussed and discarded many plans for crossing the eighth chamber. From where we stood we saw that the fighting among the apts was growing less, and that many that had been feeding had ceased and lain down to sleep.

Presently it became apparent that in a short time all the ferocious monsters might be peacefully slumbering, and thus a hazardous opportunity be presented to us to cross through their lair.

One by one the remaining brutes stretched themselves upon the bubbling decomposition that covered the mass of bones upon the floor of their den, until but a single apt remained awake. This huge fellow roamed restlessly about, nosing among his companion and the abhorrent litter of the cave.

Occasionally he would stop to peer intently toward first one of the exits from the chamber and then the other. His whole demeanor was as of one who acts as sentry.

We were at last forced to the belief that he would not sleep while the other occupants of the lair slept, and so cast about in our minds for some scheme whereby we might trick him. Finally I suggested a plan to Thuvan Dihn, and as it seemed as good as any that we had discussed we decided to put it to the test.

To this end Thuvan Dihn placed himself close against the cave's wall, beside the entrance to the eighth chamber, while I deliberately showed myself to the guardian apt as he looked toward our retreat. Then I sprang to the opposite side of the entrance, flattening my body close to the wall.

Without a sound the great beast moved rapidly toward the seventh cave to see what manner of intruder had thus rashly penetrated so far within the precincts of his habitation.

As he poked his head through the narrow aperture that connects the two caves a heavy long-sword was awaiting him upon either hand, and before he had an opportunity to emit even a single growl his severed head rolled at our feet.

Quickly we glanced into the eighth chamber—not an apt had moved. Crawling over the carcass of the huge beast that blocked the doorway Thuvan Dihn and I cautiously entered the forbidding and dangerous den.

Like snails we wound our silent and careful way among the huge, recumbent forms. The only sound above our breathing was the sucking noise of our feet as we lifted them from the ooze of decaying flesh through which we crept.

Halfway across the chamber and one of the mighty beasts directly before me moved restlessly at the very instant that my foot was poised above his head, over which I must step.

Breathlessly I waited, balancing upon one foot, for I did not dare move a muscle. In my right hand was my keen short-sword, the point hovering an inch above the thick fur beneath which beat the savage heart.

Finally the apt relaxed, sighing, as with the passing of a bad dream, and resumed the regular respiration of deep slumber. I planted my raised foot beyond the fierce head and an instant later had stepped over the beast.

Thuvan Dihn followed directly after me, and another moment found us at the further door, undetected.

The Carrion Caves consist of a series of twenty-seven connecting chambers, and present the appearance of having been eroded by running water in some far-gone age when a mighty river found its way to the south through this single breach in the barrier of rock and ice that hems the country of the pole.

Thuvan Dihn and I traversed the remaining nineteen caverns without adventure or mishap.

We were afterward to learn that but once a month is it possible to find all the apts of the Carrion Caves in a single chamber.

At other times they roam singly or in pairs in and out of the caves, so that it would have been practically impossible for two men to have passed through the entire twenty-seven chambers without encountering an apt in nearly every one of them. Once a month they sleep for a full day, and it was our good fortune to stumble by accident upon one of these occasions.

Beyond the last cave we emerged into a desolate country of snow and ice, but found a well-marked trail leading north. The way was boulder-strewn, as had been that south of the barrier, so that we could see but a short distance ahead of us at any time.

After a couple of hours we passed round a huge boulder to come to a steep declivity leading down into a valley.

Directly before us we saw a half dozen men—fierce, black-bearded fellows, with skins the color of a ripe lemon.

"The yellow men of Barsoom!" ejaculated Thuvan Dihn, as though even now that he saw them he found it scarce possible to believe that the very race we expected to find hidden in this remote and inaccessible land did really exist.

We withdrew behind an adjacent boulder to watch the actions of the little party, which stood huddled at the foot of another huge rock, their backs toward us.

One of them was peering round the edge of the granite mass as though watching one who approached from the opposite side.

Presently the object of his scrutiny came within the range of my vision and I saw that it was another yellow man. All were clothed in magnificent furs—the six in the black and yellow striped hide of the orluk, while he who approached alone was resplendent in the pure white skin of an apt.

The yellow men were armed with two swords, and a short javelin was slung across the back of each, while from their left arms hung cuplike shields no larger than a dinner plate, the concave sides of which turned outward toward an antagonist.

They seemed puny and futile implements of safety against an even ordinary swordsman, but I was later to see the purpose of them and with what wondrous dexterity the yellow men manipulate them.

One of the swords which each of the warriors carried caught my immediate attention. I call it a sword, but really it was a sharp-edged blade with a complete hook at the far end.

The other sword was of about the same length as the hooked instrument, and somewhere between that of my long-sword and my short-sword. It was straight and two-edged. In addition to the weapons I have enumerated each man carried a dagger in his harness.

As the white-furred one approached, the six grasped their swords more firmly—the hooked instrument in the left hand, the straight sword in the right, while above the left wrist the small shield was held rigid upon a metal bracelet.

As the lone warrior came opposite them the six rushed out upon him with fiendish yells that resembled nothing more closely than the savage war cry of the Apaches of the South-west.

Instantly the attacked drew both his swords, and as the six fell upon him I witnessed as pretty fighting as one might care to see.

With their sharp hooks the combatants attempted to take hold of an adversary, but like lightning the cupshaped shield would spring before the darting weapon and into its hollow the hook would plunge.

Once the lone warrior caught an antagonist in the side with his hook, and drawing him close ran his sword through him.

But the odds were too unequal, and, though he who fought alone was by far the best and bravest of them all, I saw that it was but a question of time before the remaining five would find an opening through his marvelous guard and bring him down.

Now my sympathies have ever been with the weaker side of an argument, and though I knew nothing of the cause of the trouble I could not stand idly by and see a brave man butchered by superior numbers.

As a matter of fact I presume I gave little attention to seeking an excuse, for I love a good fight too well to need any other reason for joining in when one is afoot.

So it was that before Thuvan Dihn knew what I was about he saw me standing by the side of the white-clad yellow man, battling like mad with his five adversaries.



WITH THE YELLOW MEN

Thuvan Dihn was not long in joining me; and, though we found the hooked weapon a strange and savage thing with which to deal, the three of us soon despatched the five black-bearded warriors who opposed us.

When the battle was over our new acquaintance turned to me, and removing the shield from his wrist, held it out. I did not know the significance of his act, but judged that it was but a form of expressing his gratitude to me.

I afterward learned that it symbolized the offering of a man's life in return for some great favor done him; and my act of refusing, which I had immediately done, was what was expected of me.

"Then accept from Talu, Prince of Marentina," said the yellow man, "this token of my gratitude," and reaching beneath one of his wide sleeves he withdrew a bracelet and placed it upon my arm. He then went through the same ceremony with Thuvan Dihn.

Next he asked our names, and from what land we hailed. He seemed quite familiar with the geography of the outerworld, and when I said I was from Helium he raised his brows.

"Ah," he said, "you seek your ruler and his company?"

"Know you of them?" I asked.

"But little more than that they were captured by my uncle, Salensus Oll, Jeddak of Jeddaks, Ruler of Okar, land of the yellow men of Barsoom. As to their fate I know nothing, for I am at war with my uncle, who would crush my power in the principality of Marentina.

"These from whom you have just saved me are warriors he has sent out to find and slay me, for they know that often I come alone to hunt and kill the sacred apt which Salensus Oll so much reveres. It is partly because I hate his religion that Salensus Oll hates me; but mostly does he fear my growing power and the great faction which has arisen throughout Okar that would be glad to see me ruler of Okar and Jeddak of Jeddaks in his place.

"He is a cruel and tyrannous master whom all hate, and were it not for the great fear they have of him I could raise an army overnight that would wipe out the few that might remain loyal to him. My own people are faithful to me, and the little valley of Marentina has paid no tribute to the court of Salensus Oll for a year.

"Nor can he force us, for a dozen men may hold the narrow way to Marentina against a million. But now, as to thine own affairs. How may I aid you? My palace is at your disposal, if you wish to honor me by coming to Marentina."

"When our work is done we shall be glad to accept your invitation," I replied. "But now you can assist us most by directing us to the court of Salensus Oll, and suggesting some means by which we may gain admission to the city and the palace, or whatever other place we find our friends to be confined."

Talu gazed ruefully at our smooth faces and at Thuvan Dihn's red skin and my white one.

"First you must come to Marentina," he said, "for a great change must be wrought in your appearance before you can hope to enter any city in Okar. You must have yellow faces and black beards, and your apparel and trappings must be those least likely to arouse suspicion. In my palace is one who can make you appear as truly yellow men as does Salensus Oll himself."

His counsel seemed wise; and as there was apparently no other way to insure a successful entry to Kadabra, the capital city of Okar, we set out with Talu, Prince of Marentina, for his little, rock-bound country.

The way was over some of the worst traveling I have ever seen, and I do not wonder that in this land where there are neither thoats nor fliers that Marentina is in little fear of invasion; but at last we reached our destination, the first view of which I had from a slight elevation a half-mile from the city.

Nestled in a deep valley lay a city of Martian concrete, whose every street and plaza and open space was roofed with glass. All about lay snow and ice, but there was none upon the rounded, domelike, crystal covering that enveloped the whole city.

Then I saw how these people combated the rigors of the arctic, and lived in luxury and comfort in the midst of a land of perpetual ice. Their cities were veritable hothouses, and when I had come within this one my respect and admiration for the scientific and engineering skill of this buried nation was unbounded.

The moment we entered the city Talu threw off his outer garments of fur, as did we, and I saw that his apparel differed but little from that of the red races of Barsoom. Except for his leathern harness, covered thick with jewels and metal, he was naked, nor could one have comfortably worn apparel in that warm and humid atmosphere.

For three days we remained the guests of Prince Talu, and during that time he showered upon us every attention and courtesy within his power. He showed us all that was of interest in his great city.

The Marentina atmosphere plant will maintain life indefinitely in the cities of the north pole after all life upon the balance of dying Mars is extinct through the failure of the air supply, should the great central plant again cease functioning as it did upon that memorable occasion that gave me the opportunity of restoring life and happiness to the strange world that I had already learned to love so well.

He showed us the heating system that stores the sun's rays in great reservoirs beneath the city, and how little is necessary to maintain the perpetual summer heat of the glorious garden spot within this arctic paradise.

Broad avenues of sod sewn with the seed of the ocher vegetation of the dead sea bottoms carried the noiseless traffic of light and airy ground fliers that are the only form of artificial transportation used north of the gigantic ice-barrier.

The broad tires of these unique fliers are but rubber-like gas bags filled with the eighth Barsoomian ray, or ray of propulsion—that remarkable discovery of the Martians that has made possible the great fleets of mighty airships that render the red man of the outer world supreme. It is this ray which propels the inherent or reflected light of the planet off into space, and when confined gives to the Martian craft their airy buoyancy.

The ground fliers of Marentina contain just sufficient buoyancy in their automobile-like wheels to give the cars traction for steering purposes; and though the hind wheels are geared to the engine, and aid in driving the machine, the bulk of this work is carried by a small propeller at the stern.

I know of no more delightful sensation than that of riding in one of these luxuriously appointed cars which skim, light and airy as feathers, along the soft, mossy avenues of Marentina. They move with absolute noiselessness between borders of crimson sward and beneath arching trees gorgeous with the wondrous blooms that mark so many of the highly cultivated varieties of Barsoomian vegetation.

By the end of the third day the court barber—I can think of no other earthly appellation by which to describe him—had wrought so remarkable a transformation in both Thuvan Dihn and myself that our own wives would never have known us. Our skins were of the same lemon color as his own, and great, black beards and mustaches had been deftly affixed to our smooth faces. The trappings of warriors of Okar aided in the deception; and for wear beyond the hothouse cities we each had suits of the black- and yellow-striped orluk.

Talu gave us careful directions for the journey to Kadabra, the capital city of the Okar nation, which is the racial name of the yellow men. This good friend even accompanied us part way, and then, promising to aid us in any way that he found possible, bade us adieu.

On parting he slipped upon my finger a curiously wrought ring set with a dead-black, lusterless stone, which appeared more like a bit of bituminous coal than the priceless Barsoomian gem which in reality it is.

"There had been but three others cut from the mother stone," he said, "which is in my possession. These three are worn by nobles high in my confidence, all of whom have been sent on secret missions to the court of Salensus Oll.

"Should you come within fifty feet of any of these three you will feel a rapid, pricking sensation in the finger upon which you wear this ring. He who wears one of its mates will experience the same feeling; it is caused by an electrical action that takes place the moment two of these gems cut from the same mother stone come within the radius of each other's power. By it you will know that a friend is at hand upon whom you may depend for assistance in time of need.

"Should another wearer of one of these gems call upon you for aid do not deny him, and should death threaten you swallow the ring rather than let it fall into the hands of enemies. Guard it with your life, John Carter, for some day it may mean more than life to you."

With this parting admonition our good friend turned back toward Marentina, and we set our faces in the direction of the city of Kadabra and the court of Salensus Oll, Jeddak of Jeddaks.

That very evening we came within sight of the walled and glass-roofed city of Kadabra. It lies in a low depression near the pole, surrounded by rocky, snow-clad hills. From the pass through which we entered the valley we had a splendid view of this great city of the north. Its crystal domes sparkled in the brilliant sunlight gleaming above the frost-covered outer wall that circles the entire one hundred miles of its circumference.

At regular intervals great gates give entrance to the city; but even at the distance from which we looked upon the massive pile we could see that all were closed, and, in accordance with Talu's suggestion, we deferred attempting to enter the city until the following morning.

As he had said, we found numerous caves in the hillsides about us, and into one of these we crept for the night. Our warm orluk skins kept us perfectly comfortable, and it was only after a most refreshing sleep that we awoke shortly after daylight on the following morning.

Already the city was astir, and from several of the gates we saw parties of yellow men emerging. Following closely each detail of the instructions given us by our good friend of Marentina, we remained concealed for several hours until one party of some half dozen warriors had passed along the trail below our hiding place and entered the hills by way of the pass along which we had come the previous evening.

After giving them time to get well out of sight of our cave, Thuvan Dihn and I crept out and followed them, overtaking them when they were well into the hills.

When we had come almost to them I called aloud to their leader, when the whole party halted and turned toward us. The crucial test had come. Could we but deceive these men the rest would be comparatively easy.

"Kaor!" I cried as I came closer to them.

"Kaor!" responded the officer in charge of the party.

"We be from Illall," I continued, giving the name of the most remote city of Okar, which has little or no intercourse with Kadabra. "Only yesterday we arrived, and this morning the captain of the gate told us that you were setting out to hunt orluks, which is a sport we do not find in our own neighborhood. We have hastened after you to pray that you allow us to accompany you."

The officer was entirely deceived, and graciously permitted us to go with them for the day. The chance guess that they were bound upon an orluk hunt proved correct, and Talu had said that the chances were ten to one that such would be the mission of any party leaving Kadabra by the pass through which we entered the valley, since that way leads directly to the vast plains frequented by this elephantine beast of prey.

In so far as the hunt was concerned, the day was a failure, for we did not see a single orluk; but this proved more than fortunate for us, since the yellow men were so chagrined by their misfortune that they would not enter the city by the same gate by which they had left it in the morning, as it seemed that they had made great boasts to the captain of that gate about their skill at this dangerous sport.

We, therefore, approached Kadabra at a point several miles from that at which the party had quitted it in the morning, and so were relieved of the danger of embarrassing questions and explanations on the part of the gate captain, whom we had said had directed us to this particular hunting party.

We had come quite close to the city when my attention was attracted toward a tall, black shaft that reared its head several hundred feet into the air from what appeared to be a tangled mass of junk or wreckage, now partially snow-covered.
