“The therns for their part have temples dotted about the entire civilized world. Here priests whom the people never see communicate the doctrine of the Mysterious River Iss, the Valley Dor, and the Lost Sea of Korus to persuade the poor deluded creatures to take the voluntary pilgrimage that swells the wealth of the Holy Therns and adds to the numbers of their slaves.
“Thus the therns are used as the principal means for collecting the wealth and labour that the First Born wrest from them as they need it. Occasionally the First Born themselves make raids upon the outer world. It is then that they capture many females of the royal houses of the red men, and take the newest in battleships and the trained artisans who build them, that they may copy what they cannot create.
“We are a nonproductive race, priding ourselves upon our nonproductiveness. It is criminal for a First Born to labour or invent. That is the work of the lower orders, who live merely that the First Born may enjoy long lives of luxury and idleness. With us fighting is all that counts; were it not for that there would be more of the First Born than all the creatures of Barsoom could support, for in so far as I know none of us ever dies a natural death. Our females would live forever but for the fact that we tire of them and remove them to make place for others. Issus alone of all is protected against death. She has lived for countless ages.”
“Would not the other Barsoomians live forever but for the doctrine of the voluntary pilgrimage which drags them to the bosom of Iss at or before their thousandth year?” I asked him.
“I feel now that there is no doubt but that they are precisely the same species of creature as the First Born, and I hope that I shall live to fight for them in atonement of the sins I have committed against them through the ignorance born of generations of false teaching.”
As he ceased speaking a weird call rang out across the waters of Omean. I had heard it at the same time the previous evening and knew that it marked the ending of the day, when the men of Omean spread their silks upon the deck of battleship and cruiser and fall into the dreamless sleep of Mars.
Our guard entered to inspect us for the last time before the new day broke upon the world above. His duty was soon performed and the heavy door of our prison closed behind him—we were alone for the night.
I gave him time to return to his quarters, as Xodar said he probably would do, then I sprang to the grated window and surveyed the nearby waters. At a little distance from the island, a quarter of a mile perhaps, lay a monster battleship, while between her and the shore were a number of smaller cruisers and one-man scouts. Upon the battleship alone was there a watch. I could see him plainly in the upper works of the ship, and as I watched I saw him spread his sleeping silks upon the tiny platform in which he was stationed. Soon he threw himself at full length upon his couch. The discipline on Omean was lax indeed. But it is not to be wondered at since no enemy guessed the existence upon Barsoom of such a fleet, or even of the First Born, or the Sea of Omean. Why indeed should they maintain a watch?
Presently I dropped to the floor again and talked with Xodar, describing the various craft I had seen.
“There is one there,” he said, “my personal property, built to carry five men, that is the swiftest of the swift. If we can board her we can at least make a memorable run for liberty,” and then he went on to describe to me the equipment of the boat; her engines, and all that went to make her the flier that she was.
In his explanation I recognized a trick of gearing that Kantos Kan had taught me that time we sailed under false names in the navy of Zodanga beneath Sab Than, the Prince. And I knew then that the First Born had stolen it from the ships of Helium, for only they are thus geared. And I knew too that Xodar spoke the truth when he lauded the speed of his little craft, for nothing that cleaves the thin air of Mars can approximate the speed of the ships of Helium.
We decided to wait for an hour at least until all the stragglers had sought their silks. In the meantime I was to fetch the red youth to our cell so that we would be in readiness to make our rash break for freedom together.
I sprang to the top of our partition wall and pulled myself up on to it. There I found a flat surface about a foot in width and along this I walked until I came to the cell in which I saw the boy sitting upon his bench. He had been leaning back against the wall looking up at the glowing dome above Omean, and when he spied me balancing upon the partition wall above him his eyes opened wide in astonishment. Then a wide grin of appreciative understanding spread across his countenance.
As I stooped to drop to the floor beside him he motioned me to wait, and coming close below me whispered: “Catch my hand; I can almost leap to the top of that wall myself. I have tried it many times, and each day
