Never had I had the heart to punish Woola during the long years that had passed since that first day upon Mars when the green jed of the Tharks had placed him on guard over me, and I had won his love and loyalty from the cruel and loveless masters of his former life, yet I believe he would have submitted to any cruelty that I might have inflicted upon him, so wondrous was his affection for me.
The diadem in the center of the circlet of gold upon the brow of Lakor proclaimed him a Holy Thern, while his companion, not thus adorned, was a lesser thern, though from his harness I gleaned that he had reached the Ninth Cycle, which is but one below that of the Holy Therns.
As I stood for a moment looking at the gruesome havoc Woola had wrought, there recurred to me the memory of that other occasion upon which I had masqueraded in the wig, diadem, and harness of Sator Throg, the Holy Thern whom Thuvia of Ptarth had slain, and now it occurred to me that it might prove of worth to utilize Lakor’s trappings for the same purpose.
A moment later I had torn his yellow wig from his bald pate and transferred it and the circlet, as well as all his harness, to my own person.
Woola did not approve of the metamorphosis. He sniffed at me and growled ominously, but when I spoke to him and patted his huge head he at length became reconciled to the change, and at my command trotted off along the corridor in the direction we had been going when our progress had been interrupted by the therns.
We moved cautiously now, warned by the fragment of conversation I had overheard. I kept abreast of Woola that we might have the benefit of all our eyes for what might appear suddenly ahead to menace us, and well it was that we were forewarned.
At the bottom of a flight of narrow steps the corridor turned sharply back upon itself, immediately making another turn in the original direction, so that at that point it formed a perfect letter S, the top leg of which debouched suddenly into a large chamber, illy lighted, and the floor of which was completely covered by venomous snakes and loathsome reptiles.
To have attempted to cross that floor would have been to court instant death, and for a moment I was almost completely discouraged. Then it occurred to me that Thurid and Matai Shang with their party must have crossed it, and so there was a way.
Had it not been for the fortunate accident by which I overheard even so small a portion of the therns’ conversation we should have blundered at least a step or two into that wriggling mass of destruction, and a single step would have been all-sufficient to have sealed our doom.
These were the only reptiles I had ever seen upon Barsoom, but I knew from their similarity to the fossilized remains of supposedly extinct species I had seen in the museums of Helium that they comprised many of the known prehistoric reptilian genera, as well as others undiscovered.
