iety as to the reason of his leaving
Dejah Thoris. Only her death I felt sure, could account for his
absence from her, so faithful I knew him to be to my commands.

By the light of the now brilliant moons I saw that he was but a shadow
of his former self, and as he turned from my caress and commenced
greedily to devour the dead carcass at my feet I realized that the poor
fellow was more than half starved. I, myself, was in but little better
plight but I could not bring myself to eat the uncooked flesh and I had
no means of making a fire. When Woola had finished his meal I again
took up my weary and seemingly endless wandering in quest of the
elusive waterway.

At daybreak of the fifteenth day of my search I was overjoyed to see
the high trees that denoted the object of my search. About noon I
dragged myself wearily to the portals of a huge building which covered
perhaps four square miles and towered two hundred feet in the air. It

you are of the figure of a red man. In color you are neither green nor
red. In the name of the ninth day, what manner of creature are you?"

"I am a friend of the red men of Barsoom and I am starving. In the
name of humanity open to us," I replied.

Presently the door commenced to recede before me until it had sunk into
the wall fifty feet, then it stopped and slid easily to the left,
exposing a short, narrow corridor of concrete, at the further end of
which was another door, similar in every respect to the one I had just
passed. No one was in sight, yet immediately we passed the first door
it slid gently into place behind us and receded rapidly to its original
position in the front wall of the building. As the door had slipped
aside I had noted its great thickness,
