"A thousand, if it pleases you, my dear," I assured her as I kissed her. "And now, good-by! I'll doubtless be back within the hour." That was a year ago!

As I ran up the ramp toward the hangar on the palace roof, I had, for some then unaccountable reason, a sense of impending ill; but I attributed it to the fact that my tкte-а-tкte with my princess had been so quickly interrupted.

The thin air of dying Mars renders the transition from day to night startlingly sudden to an earthman. Twilight is of short duration owing to the negligible refraction of the sun's rays. When I had left Dejah Thoris, the sun, though low, was still shining; the garden was in shadow, but it was still daylight. When I stepped from the head of the ramp to that part of the roof of the palace where the hangar was located which housed the private fliers of the family, dim twilight partially obscured my vision. It would soon be dark. I wondered why the hangar guard had not switched on the lights.

In the very instant that I realized that something was amiss, a score of men surrounded and overpowered me before I could draw and defend myself. A voice cautioned me to silence. It was the voice of the man who had summoned me into this trap, When the others spoke, it was in a language I had never heard before. They spoke in dismal, hollow monotone, expressionless, sepulchral.

They had thrown me face down upon the pavement and trussed my wrists behind my back. Then they jerked me roughly to my feet. Now, for the first time, I obtained a fairly good sight of my captors. I was appalled. I could not believe my own eyes. These things were not men. They were human skeletons! Black eye sockets looked out from grinning skulls. Bony, skeletal fingers grasped my arms. It seemed to me that I could see every bone in each body. Yet the things were alive! They moved. They spoke. They dragged me toward a strange craft that I had not before noticed.
