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.
