I was escorted through still magnificent avenues flanked by beautiful buildings, still beautiful in decay. I think I have never seen such inspiring architecture, nor construction so enduring. I do not know how old these buildings are, but I have heard Martian savants argue that the original dominant race of white-skinned, yellow-haired people flourished fully a million years ago. It seems incredible that their works should still exist; but there are many things on Mars incredible to the narrow, earthbound men of our little speck of dust.

At last we halted before a tiny gate in a colossal, fortress-like edifice in which there was no other opening than this small gate for fifty feet above the ground. From a balcony fifty feet above the gate a sentry looked down upon us.

"Who comes?" he demanded, although he could doubtless see who came, and must have recognized Lan Sohn Wen.

"It is Lan Sohn Wen, Dwar, commanding the 1st Utan of The Jeddak's Guard, with a prisoner," replied Lan Sohn Wen.

The sentry appeared bewildered. "My orders are to admit no strangers," he said, "but to kill them immediately."

"Summon the commander of the guard," snapped Lan Sohn Wen, and presently an officer came onto the balcony with the sentry.

"What is this?" he demanded. "No prisoner has ever been brought into the citadel of Horz. You know the law."

"This is an emergency," said Lan Sohn Wen. "I must bring this man before Ho Ran Kim. Open the gate!"

"Only on orders from Ho Ran Kim himself," replied the commander of the guard.

"Then go get the orders," said Lan Sohn Wen. "Tell the Jeddak that I strongly urge him to receive me with this prisoner. He is not as other prisoners who have fallen into our hands in times past."

The officer re-entered the citadel and was gone for perhaps fifteen minutes when the little gate before which we stood swung outward, and we were motioned in by the commander of the guard himself.

"The Jeddak will receive you," he said to the dwar, Lan Sohn Wen.

The citadel was an enormous walled city within the ancient city of Horz. It was quite evidently impregnable to any but attack by air. Within were pleasant avenues, homes, gardens, shops. Happy, carefree people stopped to look at me in astonishment as I was conducted down a broad boulevard toward a handsome building. It was the palace of the Jeddak, Ho Ran Kim. A sentry stood upon either side of the portal. There was no other guard; and these two were there more as a formality and as messengers than for protection, for within the walls of the citadel no man needed protection from another; as I was to learn.
