The ship carried me diagonally across the avenue upon which stood the building that harbored Ur Jan's band. I thought surely that I must hit the eaves of the opposite building; and, believe me, I put every ounce of my strength and agility into climbing that rope, as I swung rapidly across the avenue.

In this instance, however, Fate favored me; and I skimmed just above the roof of the building.

The assassins were still firing at me, but I imagine that most of their hits in the past had been scored with daggers of poison, for their pistol practice was execrable.

At last my fingers closed over the gunwale of my ship, and a moment later I had drawn myself to her deck. Reaching for her controls, I opened the throttle wide and set her nose for Helium.

Perhaps I was reckless, for I ignored the threat of the patrol boats and made no effort to escape their vigilance. Nothing mattered to me now but to reach Helium in time to safeguard my princess.

How well my enemies knew where to strike at me! How well they knew my vulnerable parts! They knew that nothing I possessed, including my life, would I refuse to give for the preservation of Dejah Thoris. They must have known, too, the price that they would have to pay if harm befell her; and this fact marked them for the desperate men that they were. I had threatened their security and their lives, and they were risking all in this attempt to defeat me.

I wondered if any of them had recognized me. I had not seen Rapas at the window; and, in the darkness of the night, there seemed little likelihood that the other two assassins, who had seen me but momentarily in the eating-place, could have been sure that it was I whom they saw for a second dangling at the end of a twirling rope. I felt that they might have suspected that it was Vandor, but I hoped that they were not sure that it was John Carter.

My swift craft moved rapidly across the city of Zodanga; and I thought that I was going to get away without difficulty, when suddenly I heard the warning wail of a patrol boat, signalling me to stop.

It was considerably above me, and slightly ahead and to the starboard, when it discovered me. My throttle was open wide, and I was racing through the thin air of the dying planet at full speed.

The patrol boat must have realized instantly that I had no intention of stopping, for it shot forward in a burst of speed, at the same time diving for me. Its velocity in that long dive was tremendous; and though it was, normally, not as fast a craft as mine, its terrific speed in the dive was far greater than my craft could attain.

I was already too low to gain speed by diving, nor could I thus have equalled the great speed of the larger craft, the weight of which added to its momentum.

It was coming right down on top of me and overhauling me rapidly- coming diagonally from my starboard side.

It seemed futile to hope that I could escape it; and when it opened up on me with its bow guns, I almost had it in my mind to give up the fight and surrender, for at least then I should be alive. Otherwise, I should be dead; and dead I could be of no help to Dejah Thoris. But I was faced then with the fact that I would be delayed, that I might not be able to reach Helium in time. I was sure to be arrested, and almost certainly I would be imprisoned for attempting to escape the patrol boat. I had no papers, and that would make it all the harder for me. I stood an excellent chance of being thrown into slavery, or into the pits beneath the city to await the coming games.

The risk was too great. I must reach Helium without delay.

Suddenly I swung my helm to starboard; and, so quickly the little craft obeyed my will, I came very near to being catapulted from her deck as she swung suddenly into the new course.

I tacked directly beneath the hull of the patrol boat as she hurtled close above me; and thus she could not fire upon me, as her guns were masked by her own hull.

Now it was that her greater weight and the speed of her dive worked to my advantage. They could not check the velocity of this larger ship and turn her onto the new course with the same facility with which I had maneuvered my lighter one-man craft.

The result was that before she was on my trail again, I had passed far beyond the outer walls of Zodanga; and, running as I was without lights, the patrol boat could not pick me up.

I saw her own lights for a few moments, but I could tell that she was not upon the right course; and then, with a sigh of relief, I settled myself for the long journey to Helium.

As I sped through the thin air of dying Mars, Thuria rose above the Western horizon ahead, flooding with her brilliant light the vast expanse of dead sea bottoms where once rolled mighty oceans bearing on their bosoms the great ships of the glorious race that then dominated the young planet.

I passed their ruined cities upon the verges of these ancient seas; and in my imagination I peopled them with happy, carefree throngs. There again were the great jeddaks who ruled them and the warrior clans that defended them. Now all were gone, and doubtless the dark recesses of their stately buildings housed some wild tribe of cruel and mirthless green men.

And so I sped across the vast expanse of waste land toward The Twin Cities of Helium and the woman I loved-the woman whose deathless beauty was the toast of a world.

I had set my destination compass on my goal, and now I stretched myself upon the deck of my flier and slept.

It is a long and lonely journey from Zodanga to Helium, and this time it seemed stretched to interminable length because of my anxiety for the safety of my princess, but at last it was ended, and I saw the scarlet tower of greater Helium looming before me.

As I approached the city, a patrol boat stopped me and ordered me alongside.

During the day, I had removed the red pigment from my skin; and even before I gave my name, the officer in command of the patrol boat recognized me.

I thought I noticed some restraint and embarrassment in his manner, but he said nothing other than to greet me respectfully and ask if his ship might escort me to my palace.

I thanked him and asked him to follow me so that I would not be detained by other patrol boats; and when I was safely above my own hangars, he dipped his bow and left.

As I alighted on the roof, the hangar guard ran forward to take the ship and run her into her hangar.

These men were old and loyal retainers who had been in my service for years.

Ordinarily, they greeted me with enthusiasm when I returned from an absence, their manner toward me, while always respectful, being more that of old servants than strictly military retainers; but tonight they greeted me with averted eyes and seemed ill at ease.

I did not question them, though I felt intuitively that something was amiss.

Instead, I hastened down the ramp into my palace and made my way immediately toward the quarters of my princess.

As I approached them, I met a young officer of her personal guard; and when he saw me he came rapidly to meet me. His face looked lined and careworn, and I could see that he was laboring under suppressed emotions.

"What is wrong, Jat Or?" I demanded; "first the commander of the patrol boat, then the hangar guard, and now you all look as though you had lost your last friend."

"We have lost our best friend," he replied.

I knew what he meant, but I hesitated to demand a direct explanation. I did not want to hear it. I shrank from hearing the words that I knew he would speak, as I had never shrunk from anything before in my life, not even a rendezvous with death.

But Jat Or was a soldier, and so was I; and however painful a duty may be, a soldier must face it bravely.

"When did they take her?" I asked.

He looked at me in wide-eyed astonishment. "You know, sir?" he exclaimed.
