Finally convinced that he could not come at me by this avenue, I set about taking stock of my situation. Circling the tower I examined its outward architecture by the simple expedient of leaning far outward above each of the four sides. Three sides terminated at the roof of the building a hundred and fifty feet below me, while the fourth extended to the pavement of the courtyard two hundred feet below. Like much of the architecture of ancient Barsoom, the surface of the tower was elaborately carved from top to bottom and at each level there were window embrasures, some of which were equipped with small stone balconies. As a rule there was but a single window to a level, and as the window for the level directly beneath never opened upon the same side of the tower as the window for the level above, there was always a distance of from thirty to forty feet between windows upon the same side, and, as I was examining the outside of the tower with a view to its offering me an avenue of escape, this point was of great importance to me, since a series of window ledges, one below another, would have proved a most welcome sight to a man in my position.
By the time I had completed my survey of the exterior of the tower, the ape had evidently come to the conclusion that he could not demolish the barrier that kept him from me and I hoped that he would abandon the idea entirely and depart. But when I lay down on the floor and placed an ear close to the door I could plainly hear him just below as he occasionally changed from one uncomfortable position to another upon the small ladder beneath me. I did not know to what extent these creatures might have developed pertinacity of purpose, but I hoped that he might soon tire of his vigil and his thoughts be diverted into some other channel. However, as the day wore to a close this possibility seemed to grow more and more remote until at last I became almost convinced that the creature had determined to lay siege until hunger or desperation forced me from my retreat.
How longingly I gazed at the beckoning hills beyond the city where lay my route toward the southwest-toward fabled Jahar.
The sun was low in the west. Soon would come the sudden transition from daylight to darkness, and then what? Perhaps the creature would abandon its vigil; hunger or thirst might attract it elsewhere, but how was I to know? How easily it might descend to the bottom of the tower and await me there, confident that sooner or later I must come down.
One unfamiliar with the traits of these savage creatures might wonder why, armed as I was with sword and pistol, I did not raise the trap door and give battle to my jailer. Had I known positively that he was the only white ape in the vicinity I should not have hesitated to do so, but experience assured me that there was doubtless an entire herd of them quartered in the ruined city. So scarce is the flesh they crave that it is their ordinary custom to hunt alone, so that in the event that they make a kill they may be more certain of retaining the prize for themselves, but if I should attack him he would most certainly raise such a row as to attract his fellows, in which event my chance for escape would have been reduced to the ultimate zero.
A single shot from my pistol might have dispatched him, but it was equally possible that it would not, for these great white apes of Barsoom are tremendous creatures, endowed with almost unbelievable vitality. Many of them stand fully fifteen feet in height and are endowed by nature with tremendous strength. Their very appearance is demoralizing to an enemy; their white, hairless bodies are in themselves repulsive to the eye of a red man; the great shock of white hair bristling erect upon their pates accentuates the brutality of their countenances, while their intermediary set of limbs, which they use either as arms or legs as necessity or whim suggests, render them most formidable antagonists. Quite generally they carry a club, in the use of which they are terribly proficient. One of them, therefore, seemed sufficiently a menace in itself, so that I had no desire to attract others of its kind, though I was fully aware that eventually I might be forced to carry the battle to him.
Just as the sun was setting my attention was attracted toward the water-front where the long shadows of the city were stretching far out across the dead sea bottom. Riding up the gentle acclivity toward the city was a party of green warriors, mounted upon their great savage thoats. There were perhaps twenty of them, moving silently over the soft moss that carpeted the bottom of the ancient harbor, the padded feet of their mounts giving forth no sound. Like specters, they moved in the shadows of the dying day, giving me further proof that Fate had led me to a most unfriendly shore, and then, as though to complete the trilogy of fearsome Barsoomian menaces, the roar of a banth rolled down out of the hills behind the city.
Safe from observation in the high tower above them, I watched the party as it emerged from the hollow of the harbor and rode out upon the avenue below me, and then for the first time I noted a small figure seated in front of one of the warriors. Darkness was coming swiftly now, but before the little cavalcade passed out of sight momentarily behind the corner of the building, as it entered another avenue leading toward the heart of the city, I thought that I recognized the little figure as that of a woman of my own race. That she was a captive was a foregone conclusion and I could not but shudder as I contemplated the fate that lay in store for her. Perhaps my own Sanoma Tora was in equal jeopardy. Perhaps-but no, that could not be possible-how could Sanoma Tora have fallen into the clutches of warriors of the fierce horde of Torquas?
It could not be she. No, that was impossible. But the fact remained that the captive was a red woman, and whether she were Sanoma Tora or another, whether she were from Helium or Jahar, my heart went out in sympathy to her and I forgot my own predicament as something within me urged me to pursue her captors and seek to snatch her from them; but, alas, how futile seemed my fancy. How might I, who might not even save himself, aspire to the rescue of another?
The thought galled me, it hurt my pride, and forthwith I determined that if I would not chance dying to save myself, I might at least chance it for a woman of my own race, and always in the back of my head was the thought that perhaps the object of my solicitude might, indeed, be the woman I loved.
Darkness had fallen as I pressed my ear again to the trap door. All was silent below so that presently I became assured that the creature had departed. Perhaps he was lying in wait for me further down, but what of that? I must face him eventually if he elected to remain. I loosened my pistol in its holster and was upon the point of slipping the bar that secured the door when I distinctly heard the beast directly beneath me.
For an instant I paused. What was the use? It meant certain death to raise that door, and in what way might I be profiting either myself or the poor captive if I gave my life thus uselessly? But there was an alternative-one that I had been planning to adopt in case of necessity from the moment that I had first examined the exterior construction of the tower. It offered a slender chance of escape from my predicament and even a very slender chance was better than what would confront me should I raise the trap door.
I stepped to one of the windows of the tower and looked down upon the city. Neither moon was in the sky; I could see nothing. Toward the interior of the city I heard the squealing of thoats. There would the camp of the green men be located. Thus by the squealing of their vicious mounts would I be guided to it. Again a hunting banth roared in the hills. I sat upon the sill and swung both legs across and then turning on my belly slipped silently over the edge until I hung only by my hands. Groping with my sandaled toes, I felt for a foothold upon the deep-cut carvings of the tower's face. Above me was a blue-black void shot with stars; below me a blank and empty void. It might have been a thousand sofads to the roof below me, or it might have been one; but though I could see nothing I knew that it was one hundred and fifty and that at the bottom lay death if a foot or a hand slipped.
