"Trust me," I said, "and don't call me John Carter. Can you get out of the palace of Nastor after dark?"

"I think so; they are very lax; because assassination and theft are practically unknown here, and the secret machine of the jeddak makes escape from the valley impossible. I am quite sure that I can get out. In fact, I have been sent out on errands every night since I was purchased."

"Good!" I said. "Now listen carefully: Come out of the palace and loiter in the shadows near Nastor's palace at about twenty-five xats after the eighth zode.* Bring Jad-han with you, if he wishes to escape. If my plan succeeds, a flier will land here in the plaza near you; run for it and climb aboard. It will be piloted by a Black Pirate, but don't let that deter you. If you and Jad-han can arm yourselves, do so; there may be fighting. If the flier does not come, you will know that I have failed; and you can go back to your quarters and be no worse off. If I do not come, it will be because I am dead, or about to die."

*Midnight, Earth time.

"And Llana?" he asked. "What of her?"

"My plans all center around the rescue of Llana of Gathol," I assured him. "If I fail in that, I fail in all; for I will not leave without her."

"I wish you could tell me how you expect to accomplish the impossible," he said.

"I should feel very much surer of the outcome, I know, if you would tell me at least something of your plans."

"Certainly," I said. "In the first place-"

"What are you two slaves doing loitering here?" demanded a gruff voice behind us. I turned to see a burly warrior at my shoulder. For answer, I showed him my pass from the jeddak.

Even after he read it, he looked as though he didn't believe it; but presently he handed it back to me and said, "That's all right for you, but how about this other one? Has he got a pass from the jeddak, too?"

"The fault is mine," I said. "I knew him before we were captured, and I stopped him to ask how he was faring. I am sure that if the jeddak knew, he would say that it was all right for me to talk with a friend. The jeddak has been very kind to me." I was trying to impress the fellow with the fact that his jeddak was very kindly disposed toward me. I think that I succeeded.

"Very well," he said, "but get on your way now-the Great Plaza is no place for slaves to visit with one another."

Pan Dan Chee picked up his burden and departed, and I was about to leave when the warrior detained me. "I saw you defeat Nolat and Ban-tor at the Games," he said. "We were talking about it a little while ago with some of our friends from the Valley Dor. They said that there was once a warrior came there who was just such a marvellous swordsman. His name was John Carter, and he had a white skin and gray eyes! Could your name, by any chance, be John Carter?"

"My name is Dotar Sojat," I replied.

"Our friends from the Valley Dor would like to get hold of John Carter," he said; and then, with a rather nasty little smile, he turned on his heel and left me.

Now indeed was the occasion for haste increased a hundredfold. If one man in Kamtol suspected that I might be John Carter, Prince of Helium, I should be lost by the morrow at the latest-perhaps before the morrow. Even as I entered the palace I feared arrest, but I reached my room without incident. Presently Man-lat came in; and at sight of him I expected the worst, for he had never visited me before. My sword was ready to leap from its scabbard, for I had determined to die fighting rather than let them arrest and disarm me. Even now, if Man-lat made a false move, I could kill him; and there might still be a chance that my plan could move on to successful fruition.

But Man-lat was in a friendly, almost jovial mood. "It is too bad that you are a slave," he said, "for there are going to be great doings in the palace tonight. Doxus is entertaining the visitors from Dor. There will be much to eat and much to drink, and there will be entertainment. Doxus will probably have you give an exhibition of swordplay with one of our best swordsmen-not to the death, you understand, but just for first blood. Then there will be dancing by slave girls; the nobles will enter their most beautiful. Doxus has commanded Nastor to bring a new purchase of his whose beauty has been the talk of Kamtol since the last games. Yes, it is too bad that you are not a First Born; so that you might enjoy the evening to the full."

"I am sure I shall enjoy the evening," I said.

"How's that?" he demanded.

"Didn't you say that I was going to be there?"

"Oh, yes; but only, as an entertainer. You will not eat nor drink with us, and you will not see the slave girls. It is really too bad that you are not a First Born; you would have been a credit to us."

"I feel that I am quite the equal of any of the First Born," I said, for I was pretty well fed up with their arrogance and conceit.

Man-lat looked at me in pained surprise. "You are presumptuous, slave," he said.

"Do you not know that the First Born of Barsoom, sometimes known to you lesser creatures as the Black Pirates of Barsoom, are of the oldest race on the planet. We trace our lineage, unbroken, direct to the Tree of Life which flourished in the Valley Dor twenty-three million years ago.

"For countless ages the fruit of this tree underwent the gradual changes of evolution, passing by degrees from the true plant life to a combination of plant and animal. In the first stages of this phase, the fruit of the tree possessed only the power of independent muscular action, while the stem remained attached to the parent plant; later, a brain developed in the fruit; so that, hanging there by their long stems, they thought and moved as individuals.

"Then, with the development of perceptions, came a comparison of them; judgments were reached and compared, and thus reason and the power to reason were born upon Barsoom.

"Ages passed. Many forms of life came and went upon the Tree of Life, but still all were attached to the parent plant by stems of varying lengths. In time the fruit upon the tree consisted of tiny plant men, such as we now see reproduced in such huge dimensions in the Valley Dor; but still hanging to the limbs and branches of the Tree by the stems which grew from the tops of their heads.

"The buds from which the plant men blossomed resembled large nuts about a sofad* in diameter, divided by double partition walls into four sections. In one section grew the plant man; in another a sixteen-legged worm; in the third the progenitor of the white ape; and in the fourth, the primeval black man of Barsoom."

*11.17 Earth inches.

"When the bud burst, the plant man remained dangling at the end of his stem; but the three other sections fell to the ground, where the efforts of their imprisoned occupants to escape sent them hopping about in all directions.

"Thus, as time went on, all Barsoom, was covered by these imprisoned creatures. For countless ages they lived their long lives within their hard shells, hopping and skipping about the broad planet; falling into rivers, takes, and seas to be still farther spread about the surface of the new world.

"Countless billions died before the first black man broke through his prison walls into the light of day. Prompted by curiosity, he broke open other shells; and the peopling of Barsoom commenced.

"The pure strain of the blood of this first black man has remained untainted by admixture with that of other creatures; but from the sixteen-legged worm, the first white ape, and renegade black men has sprung every other form of life upon Barsoom."

I hoped he was through, for I had heard all this many times before; but, of course, I didn't dare tell him so. I wished he would go away- not that I could do anything until after dark, but I just wanted to be alone and re-plan every minutest detail of the night's work that lay before me.
