And here now was John Carter, Prince of Helium, in need both of weapons and warriors!

As I stepped into the apartment, guards and prisoners saw me simultaneously.

Close to the entrance where I stood was a rack of straight swords, and as my hand closed upon the hilt of one of them my eyes fell upon the faces of two of the prisoners who worked side by side.

One of the guards started toward me. “Who are you?” he demanded. “What do you here?”

“I come for Tardos Mors, Jeddak of Helium, and his son, Mors Kajak,” I cried, pointing to the two red prisoners, who had now sprung to their feet, wide-eyed in astonished recognition.

“Rise, red men! Before we die let us leave a memorial in the palace of Okar’s tyrant that will stand forever in the annals of Kadabra to the honor and glory of Helium,” for I had seen that all the prisoners there were men of Tardos Mors’s navy.

Then the first guardsman was upon me and the fight was on, but scarce did we engage ere, to my horror, I saw that the red slaves were shackled to the floor.

THE MAGNET SWITCH

The guardsmen paid not the slightest attention to their wards, for the red men could not move over two feet from the great rings to which they were padlocked, though each had seized a weapon upon which he had been engaged when I entered the room, and stood ready to join me could they have but done so.

The yellow men devoted all their attention to me, nor were they long in discovering that the three of them were none too many to defend the armory against John Carter. Would that I had had my own good long-sword in my hand that day; but, as it was, I rendered a satisfactory account of myself with the unfamiliar weapon of the yellow man.
