Perhaps a thousand feet from me the river broke, as it seemed, directly from the base of the cliffs, and as there seemed not the remotest chance for escape in that direction I turned my attention again toward the forest.
The cliffs towered above me a good five thousand feet. The sun was not quite upon them and they loomed a dull yellow in their own shade. Here and there they were broken with streaks and patches of dusky red, green, and occasional areas of white quartz.
Altogether they were very beautiful, but I fear that I did not regard them with a particularly appreciative eye on this, my first inspection of them.
Just then I was absorbed in them only as a medium of escape, and so, as my gaze ran quickly, time and again, over their vast expanse in search of some cranny or crevice, I came suddenly to loathe them as the prisoner must loathe the cruel and impregnable walls of his dungeon.
Tars Tarkas was approaching me rapidly, and still more rapidly came the awful horde at his heels.
It seemed the forest now or nothing, and I was just on the point of motioning Tars Tarkas to follow me in that direction when the sun passed the cliff's zenith, and as the bright rays touched the dull surface it burst out into a million scintillant lights of burnished gold, of flaming red, of soft greens, and gleaming whites-a more gorgeous and inspiring spectacle human eye has never rested upon.
The face of the entire cliff was, as later inspection conclusively proved, so shot with veins and patches of solid gold as to quite present the appearance of a solid wall of that precious metal except where it was broken by outcroppings of ruby, emerald, and diamond boulders-a faint and alluring indication of the vast and unguessable riches which lay deeply buried behind the magnificent surface.
But what caught my most interested attention at the moment that the sun's rays set the cliff's face a-shimmer, was the several black spots which now appeared quite plainly in evidence high across the gorgeous wall close to the forest's top, and extending apparently below and behind the branches.
Almost immediately I recognised them for what they were, the dark openings of caves entering the solid walls-possible avenues of escape or temporary shelter, could we but reach them.
There was but a single way, and that led through the mighty, towering trees upon our right. That I could scale them I knew full well, but Tars Tarkas, with his mighty bulk and enormous weight, would find it a task possibly quite beyond his prowess or his skill, for Martians are at best but poor climbers. Upon the entire surface of that ancient planet I never before had seen a hill or mountain that exceeded four thousand feet in height above the dead sea bottoms, and as the ascent was usually gradual, nearly to their summits they presented but few opportunities for the practice of climbing. Nor would the Martians have embraced even such opportunities as might present themselves, for they could always find a circuitous route about the base of any eminence, and these roads they preferred and followed in preference to the shorter but more arduous ways.
However, there was nothing else to consider than an attempt to scale the trees contiguous to the cliff in an effort to reach the caves above.
The Thark grasped the possibilities and the difficulties of the plan at once, but there was no alternative, and so we set out rapidly for the trees nearest the cliff.
Our relentless pursuers were now close to us, so close that it seemed that it would be an utter impossibility for the Jeddak of Thark to reach the forest in advance of them, nor was there any considerable will in the efforts that Tars Tarkas made, for the green men of Barsoom do not relish flight, nor ever before had I seen one fleeing from death in whatsoever form it might have confronted him. But that Tars Tarkas was the bravest of the brave he had proven thousands of times; yes, tens of thousands in countless mortal combats with men and beasts. And so I knew that there was another reason than fear of death behind his flight, as he knew that a greater power than pride or honour spurred me to escape these fierce destroyers. In my case it was love-love of the divine Dejah Thoris; and the cause of the Thark's great and sudden love of life I could not fathom, for it is oftener that they seek death than life-these strange, cruel, loveless, unhappy people.
At length, however, we reached the shadows of the forest, while right behind us sprang the swiftest of our pursuers-a giant plant man with claws outreaching to fasten his bloodsucking mouths upon us.
He was, I should say, a hundred yards in advance of his closest companion, and so I called to Tars Tarkas to ascend a great tree that brushed the cliff's face while I dispatched the fellow, thus giving the less agile Thark an opportunity to reach the higher branches before the entire horde should be upon us and every vestige of escape cut off.
But I had reckoned without a just appreciation either of the cunning of my immediate antagonist or the swiftness with which his fellows were covering the distance which had separated them from me.
As I raised my long-sword to deal the creature its death thrust it halted in its charge and, as my sword cut harmlessly through the empty air, the great tail of the thing swept with the power of a grizzly's arm across the sward and carried me bodily from my feet to the ground. In an instant the brute was upon me, but ere it could fasten its hideous mouths into my breast and throat I grasped a writhing tentacle in either hand.
The plant man was well muscled, heavy, and powerful but my earthly sinews and greater agility, in conjunction with the deathly strangle hold I had upon him, would have given me, I think, an eventual victory had we had time to discuss the merits of our relative prowess uninterrupted. But as we strained and struggled about the tree into which Tars Tarkas was clambering with infinite difficulty, I suddenly caught a glimpse over the shoulder of my antagonist of the great swarm of pursuers that now were fairly upon me.
Now, at last, I saw the nature of the other monsters who had come with the plant men in response to the weird calling of the man upon the cliff's face. They were that most dreaded of Martian creatures-great white apes of Barsoom.
My former experiences upon Mars had familiarized me thoroughly with them and their methods, and I may say that of all the fearsome and terrible, weird and grotesque inhabitants of that strange world, it is the white apes that come nearest to familiarizing me with the sensation of fear.
I think that the cause of this feeling which these apes engender within me is due to their remarkable resemblance in form to our Earth men, which gives them a human appearance that is most uncanny when coupled with their enormous size.
They stand fifteen feet in height and walk erect upon their hind feet. Like the green Martians, they have an intermediary set of arms midway between their upper and lower limbs. Their eyes are very close set, but do not protrude as do those of the green men of Mars; their ears are high set, but more laterally located than are the green men's, while their snouts and teeth are much like those of our African gorilla. Upon their heads grows an enormous shock of bristly hair.
It was into the eyes of such as these and the terrible plant men that I gazed above the shoulder of my foe, and then, in a mighty wave of snarling, snapping, screaming, purring rage, they swept over me-and of all the sounds that assailed my ears as I went down beneath them, to me the most hideous was the horrid purring of the plant men.
Instantly a score of cruel fangs and keen talons were sunk into my flesh; cold, sucking lips fastened themselves upon my arteries. I struggled to free myself, and even though weighed down by these immense bodies, I succeeded in struggling to my feet, where, still grasping my long-sword, and shortening my grip upon it until I could use it as a dagger, I wrought such havoc among them that at one time I stood for an instant free.
