Amid the angry shouting of thern guardsmen we rose high above the last fortress of the Holy Therns, and then raced straight toward the northeast and Kaol, the destination which I had heard from the lips of Matai Shang.

Far ahead, a tiny speck in the distance, I made out another flier late in the afternoon. It could be none other than that which bore my lost love and my enemies.

I had gained considerably on the craft by night; and then, knowing that they must have sighted me and would show no lights after dark, I set my destination compass upon her-that wonderful little Martian mechanism which, once attuned to the object of destination, points away toward it, irrespective of every change in its location.

All that night we raced through the Barsoomian void, passing over low hills and dead sea bottoms; above long-deserted cities and populous centers of red Martian habitation upon the ribbon-like lines of cultivated land which border the globe-encircling waterways, which Earth men call the canals of Mars.

Dawn showed that I had gained appreciably upon the flier ahead of me. It was a larger craft than mine, and not so swift; but even so, it had covered an immense distance since the flight began.

The change in vegetation below showed me that we were rapidly nearing the equator. I was now near enough to my quarry to have used my bow gun; but, though I could see that Dejah Thoris was not on deck, I feared to fire upon the craft which bore her.

Thurid was deterred by no such scruples; and though it must have been difficult for him to believe that it was really I who followed them, he could not very well doubt the witness of his own eyes; and so he trained their stern gun upon me with his own hands, and an instant later an explosive radium projectile whizzed perilously close above my deck.

The black's next shot was more accurate, striking my flier full upon the prow and exploding with the instant of contact, ripping wide open the bow buoyancy tanks and disabling the engine.

So quickly did my bow drop after the shot that I scarce had time to lash Woola to the deck and buckle my own harness to a gunwale ring before the craft was hanging stern up and making her last long drop to ground.

Her stern buoyancy tanks prevented her dropping with great rapidity; but Thurid was firing rapidly now in an attempt to burst these also, that I might be dashed to death in the swift fall that would instantly follow a successful shot.

Shot after shot tore past or into us, but by a miracle neither Woola nor I was hit, nor were the after tanks punctured. This good fortune could not last indefinitely, and, assured that Thurid would not again leave me alive, I awaited the bursting of the next shell that hit; and then, throwing my hands above my head, I let go my hold and crumpled, limp and inert, dangling in my harness like a corpse.

The ruse worked, and Thurid fired no more at us. Presently I heard the diminishing sound of whirring propellers and realized that again I was safe.

Slowly the stricken flier sank to the ground, and when I had freed myself and Woola from the entangling wreckage I found that we were upon the verge of a natural forest-so rare a thing upon the bosom of dying Mars that, outside of the forest in the Valley Dor beside the Lost Sea of Korus, I never before had seen its like upon the planet.

From books and travelers I had learned something of the little-known land of Kaol, which lies along the equator almost halfway round the planet to the east of Helium.

It comprises a sunken area of extreme tropical heat, and is inhabited by a nation of red men varying but little in manners, customs, and appearance from the balance of the red men of Barsoom.

I knew that they were among those of the outer world who still clung tenaciously to the discredited religion of the Holy Therns, and that Matai Shang would find a ready welcome and safe refuge among them; while John Carter could look for nothing better than an ignoble death at their hands.

The isolation of the Kaolians is rendered almost complete by the fact that no waterway connects their land with that of any other nation, nor have they any need of a waterway since the low, swampy land which comprises the entire area of their domain self-waters their abundant tropical crops.

For great distances in all directions rugged hills and arid stretches of dead sea bottom discourage intercourse with them, and since there is practically no such thing as foreign commerce upon warlike Barsoom, where each nation is sufficient to itself, really little has been known relative to the court of the Jeddak of Kaol and the numerous strange, but interesting, people over whom he rules.

Occasional hunting parties have traveled to this out-of-the-way corner of the globe, but the hostility of the natives has usually brought disaster upon them, so that even the sport of hunting the strange and savage creatures which haunt the jungle fastnesses of Kaol has of later years proved insufficient lure even to the most intrepid warriors.

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.
