"As you have done to Xodar, now do you likewise to Thurid. Take him before Issus, bound in his own harness, that she may see with her own eyes that there be one among you now who is greater than the First Born."

"Who are you?" whispered the woman who had first suggested that I attempt to bind Thurid.

"I am a citizen of two worlds; Captain John Carter of Virginia, Prince of the House of Tardos Mors, Jeddak of Helium. Take this man to your goddess, as I have said, and tell her, too, that as I have done to Xodar and Thurid, so also can I do to the mightiest of her Dators. With naked hands, with long-sword or with short-sword, I challenge the flower of her fighting-men to combat."

"Come," said the officer who was guarding me back to Shador; "my orders are imperative; there is to be no delay. Xodar, come you also."

There was little of disrespect in the tone that the man used in addressing either Xodar or myself. It was evident that he felt less contempt for the former Dator since he had witnessed the ease with which I disposed of the powerful Thurid.

That his respect for me was greater than it should have been for a slave was quite apparent from the fact that during the balance of the return journey he walked or stood always behind me, a drawn short-sword in his hand.

The return to the Sea of Omean was uneventful. We dropped down the awful shaft in the same car that had brought us to the surface. There we entered the submarine, taking the long dive to the tunnel far beneath the upper world. Then through the tunnel and up again to the pool from which we had had our first introduction to the wonderful passageway from Omean to the Temple of Issus.

From the island of the submarine we were transported on a small cruiser to the distant Isle of Shador. Here we found a small stone prison and a guard of half a dozen blacks. There was no ceremony wasted in completing our incarceration. One of the blacks opened the door of the prison with a huge key, we walked in, the door closed behind us, the lock grated, and with the sound there swept over me again that terrible feeling of hopelessness that I had felt in the Chamber of Mystery in the Golden Cliffs beneath the gardens of the Holy Therns.

Then Tars Tarkas had been with me, but now I was utterly alone in so far as friendly companionship was concerned. I fell to wondering about the fate of the great Thark, and of his beautiful companion, the girl, Thuvia. Even should they by some miracle have escaped and been received and spared by a friendly nation, what hope had I of the succour which I knew they would gladly extend if it lay in their power.

They could not guess my whereabouts or my fate, for none on all Barsoom even dream of such a place as this. Nor would it have advantaged me any had they known the exact location of my prison, for who could hope to penetrate to this buried sea in the face of the mighty navy of the First Born? No: my case was hopeless.
