“Because my friend fights there alone,” I answered, as I hastily sought and found the keys upon the carcass of the dead custodian of this grim chamber of horrors. There were many keys upon the oval ring, but the fair Martian maid quickly selected that which sprung the great lock at her waist, and freed she hurried toward the secret panel. Again she sought out a key upon the ring. This time a slender, needle-like affair which she inserted in an almost invisible hole in the wall. Instantly the door swung upon its pivot, and the contiguous section of the floor upon which I was standing carried me with it into the chamber where Tars Tarkas fought. The great Thark stood with his back against an angle of the walls, while facing him in a semi-circle a half-dozen huge monsters crouched waiting for an opening. Their blood-streaked heads and shoulders testified to the cause of their wariness as well as to the swordsmanship of the green warrior whose glossy hide bore the same mute but eloquent witness to the ferocity of the attacks that he had so far withstood.

Like lightning the great beasts wheeled upon her, and I looked to see her torn to pieces before I could reach her side, but instead the creatures slunk to her feet like puppies that expect a merited whipping. Again she spoke to them, but in
