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.
