o a dimly lighted
apartment far below the arena.

As I rose to my feet the first thing I saw was the malignant
countenance of Issus glaring at me through the heavy bars of a grated
door at one side of the chamber.

"Rash mortal!" she shrilled. "You shall pay the awful penalty for your
blasphemy in this secret cell. Here you shall lie alone and in
darkness with the carcass of your accomplice festering in its
rottenness by your side, until crazed by loneliness and hunger you feed
upon the crawling maggots that were once a man."

That was all. In another instant she was gone, and the dim light which
had filled the cell faded into Cimmerian blackness.

"Pleasant old lady," said a voice at my side.

"Who speaks?" I asked.

"'Tis I, your companion, who has had the honour this day of fighting
shoulder to shoulder with the greatest warrior that ever wore metal

secrets of Issus of which Issus herself does not dream."

"What do you mean?"

"I laboured with the other slaves a year since in the remodelling of
these subterranean galleries, and at that time we found below these an
ancient system of corridors and chambers that had been sealed up for
ages. The blacks in charge of the work explored them, taking several
of us along to do whatever work there might be occasion for. I know
the entire system perfectly.

"There are miles of corridors honeycombing the ground beneath the
gardens and the temple itself, and there is one passage that leads down
to and connects with the lower regions that open on the water shaft
that gives passage to Omean.

"If we can reach the submarine undetected we may yet make the sea in
which there are many islands where the blacks never go. There we may
live for a time, and who knows what may transpire to aid us to escap
