Finally, I turned to him with a gesture of resignation. "Nothing seems to happen," I said.

He appeared vastly relieved. "You are a man of intelligence," he said. "If it will not obey you, it is reasonably safe to assume that it will obey no one but me."

For several moments he was lost in thought, and then he straightened up and looked at me, and his eyes burned with demoniac fire. "I can be master of a world," he said; "perhaps I can even be master of the universe."

"With that?" I asked, nodding toward the ship.

"With the idea that it symbolizes," he replied; "with the idea of an inanimate object energized by scientific means and motivated by a mechanical brain. If I but had the means to do so-the wealth-I could manufacture these brains in great quantities, and I could put them into small fliers weighing less than a man weighs. I could give them means of locomotion in the air or upon the ground. I could give them arms and hands. I could furnish them with weapons. I could send them out in great hordes to conquer the world. I could send them to other planets. They would know neither pain nor fear. They would have no hopes, no aspirations, no ambitions that might wean them from my service. They would be the creatures of my will alone, and the things that I sent them to do they would persist in until they were destroyed.

"But destroying them would serve my enemies no purpose; for faster than they could destroy them, my great factories would turn out more."

"You see," he said, "how it would work?" and he came close and spoke almost in a whisper. "The first of these mechanical men I would make with my own hands, and as I created them I would impel them to create others of their kind. They would become my mechanics, the workmen in my factories; and they would work day and night without rest, always turning out more and more of their kind. Think how rapidly they would multiply."

I was thinking of this. The possibilities astounded and stunned me. "But it would take vast wealth," I told him.

"Yes, vast wealth," he repeated; "and it was for the purpose of obtaining this vast wealth that I built this ship."

"You intend to raid the treasure houses of the great cities of Barsoom?" I asked, smiling.

"By no means," he replied. "Treasures vastly richer lie at the disposal of the man who controls this ship. Do you not know what the spectroscope tells us of the riches of Thuria?"

"I have heard," I said, "but I never took much stock in it. The story was too fabulous."

"It is true, nevertheless," he said. "There must be mountains of gold and platinum on Thuria, and vast plains carpeted with precious stones."

It was a bold enterprise; but after having seen this craft, and knowing the remarkable genius of Fal Sivas, I had little doubt but that it was feasible.

Suddenly, as was his way, he seemed to regret that he had confided in me and brusquely directed me to return to my duties in the shop.

The old man had told me so much now that I naturally began to wonder if he would consider it safe to permit me to live, and I was constantly on my guard. It seemed highly improbable that he would consent to my leaving the premises, but I determined to settle this question immediately; for I wanted to see Rapas before he could visit the establishment of Fal Sivas again, thereby compelling me to destroy him. Day after day had passed and Fal Sivas had contrived to prevent my leaving the house, though he had accomplished it so adroitly that it was never actually apparent that he did not wish me to leave.

As he dismissed me that evening, I told him that I was going out to try to locate Rapas and attempt again to contact the assassins of Ur Jan.

He hesitated so long before he replied that I thought he was going to forbid me going out, but at last he nodded in acquiescence. "Perhaps it will be as well," he said. "Rapas does not come here any more, and he knows too much to be at large, unless he is in my service and loyal to me. If I must trust one of you, I prefer that it be you, rather than Rapas."

I did not go to the evening meal with the others, as I intended eating at the place that Rapas frequented and where we had planned to meet when I was at liberty.

It was necessary to acquaint Hamas with the fact that I was leaving, as only he could open the outer door for me. His manner toward me was not quite as surly as it had been the past few days. In fact, he was almost affable; and the change in his manner put me even more on my guard, for I felt that it boded me no good-there was no reason why Hamas should love me any more today than he had yesterday. If I induced pleasant anticipations in him, it must be because he visualized something unpleasant befalling me.

From the house of Fal Sivas, I went directly to the eating-place; and there I inquired of the proprietor regarding Rapas.

"He has been in every evening," replied the man. "He usually comes about this time and again about half after the eighth zode, and he always asks me if you have been here."

"I will wait for him," I said, and I went to the table The Rat and I usually occupied.

I had scarcely seated myself before Rapas entered. He came directly to the table and seated himself opposite me.

"Where have you been keeping yourself?" he demanded. "I was commencing to think that old Fal Sivas had made away with you or that you were a prisoner in his house. I had about made up my mind to go there tonight and call on the old man, so that I could learn what had happened to you."

"It is just as well that I got out tonight before you came," I said.

"Why?" he demanded.

"Because it is not safe for you to go to the house of Fal Sivas," I told him.

"If you value your life, you will never go there again."

"What makes you think that?" he demanded.

"I can't tell you," I replied, "but just take my word for it, and keep away." I did not want him to know that I had been commissioned to kill him. It might have made him so suspicious and fearful of me that he would be of no value to me in the future.

"Well, it is strange," he said; "Fal Sivas was friendly enough before I took you there."

I saw that he was harboring in his mind the thought that, for some reason, I was trying to keep him away from Fal Sivas; but I couldn't help it, and so I changed the subject.

"Has everything been going well with you, Rapas, since I saw you?" I asked.

"Yes, quite well," he replied.

"What is the news of the city? I have not been out since I saw you last, and of course we hear little or nothing in the house of Fal Sivas."

"They say that the Warlord is in Zodanga," he replied. "Uldak, one of Ur Jan's men, was killed the last night I saw you, as you will recall. The mark of the Warlord's agent was above his heart, but Ur Jan believes that no ordinary swordsman could have bested Uldak. Also he has learned from his agent in Helium that John Carter is not there; so, putting the two facts together, Ur Jan is convinced that he must be in Zodanga."

"How interesting," I commented. "And what is Ur Jan going to do about it?"

"Oh, he'll get his revenge," said The Rat; "if not in one way, then in another. He is already planning; and when he strikes, John Carter will wish that he had attended to his own affairs and left Ur Jan alone."

Shortly before we finished our meal, a customer entered the place and took a seat alone at a table across the room. I could see him in a mirror in front of me. I saw him glance in our direction, and then I looked quickly at Rapas and saw his eyes flash a message as he nodded his head very slightly; but without that, I would have known why the man was there, for I recognized him as one of the assassins that had sat at the council with Ur Jan. I pretended not to notice anything; and my glance wandered idly to the doorway, attracted by two customers who were leaving the place at the time.
