"And in the meantime these creatures will have spread all over the world and conquered it. They will destroy your supermen. You have created a Frankensteinian host that will not only destroy you but the civilization of a world. Hasn't that possibility ever occurred to you?"

"Yes, it has; but I never intended to create these creatures in any such numbers. That is the idea of the seven jeds. I purposed developing only enough to form a small army with which to conquer Toonol, that I might regain my island and my old laboratory."

The din in the room had now risen to such proportions that further conversation was impossible. Screaming heads rolled upon the floor. Hormad warriors dragged away the newly created creatures that were considered fit to live and fresh warriors swarmed into the chamber to replace them. New hormads emerged constantly from the culture tank which swarmed with writhing life like an enormous witch's pot. And this same scene was being duplicated in forty similar rooms throughout the city of Morbus, while a stream of new hormads was pouring out of the city to be tamed and trained by officers and the more intelligent hormads.

I was delighted and relieved when Ras Thavas suggested that we inspect another phase of his work and we were permitted to leave that veritable chamber of horrors. He took us to another room where reconstruction work was carried on.

Here heads were growing new bodies and headless bodies new heads. Hormads which had lost arms or legs were growing new ones. Sometimes these activities went amiss, when nothing but a single leg sprouted from the neck of a severed head.

An identical case was among those that we saw in this room. The head was very angry about it, and became quite abusive, reviling Ras Thavas.

"What good shall I be," he demanded, "with only a head and one leg? They call you The Master Mind of Mars! Phooey! You haven't the brains of a sorak. When they produce their kind they give them a body and six legs, to say nothing of a head. Now what are you going to do about it? That's what I want to know."

"Well," said Ras Thavas, thoughtfully, "I can always redissect you and return the pieces to the culture vat."

"No! No!" screamed the head. "Let me live, but cut off this leg and let me try to grow a body."

"Very well," said Ras Thavas; "tomorrow."

"Why should a thing like that wish to live," I asked, after we had passed along.

"It is a characteristic of life, however low its form," replied Ras Thavas.

"Even these poor sexless monstrosities, whose only pleasure in life is eating raw animal tissue, wish to live. They do not even dream of the existence of love or friendship, they have no spiritual or mental resources upon which to draw for satisfaction or enjoyment; yet they wish to live."

"They speak of friendship," I said. "Tor-dur-bar's head told me not to forget that it was my friend."

"They know the word," replied Ras Thavas, "but I am sure they cannot sense its finer connotations. One of the first things they are taught is to obey. Perhaps he meant that he would obey you, serve you. He may not even remember you now.

"Some of them have practically no memories. All their reactions are purely mechanical. They respond to oft repeated stimuli-the commands to march, to fight, to come, to go, to halt. They also do what they see the majority of their fellows doing. Come! We shall find Tor-dur-bar's head and see if it recalls you. It will be an interesting experiment."

We passed into another chamber where reconstruction work was in progress, and Ras Thavas spoke to an officer in charge there. The man led us to the far end of the room where there was a large vat in which torsos were growing new arms or legs or heads, and several heads growing new bodies.

We had no more than reached the tank when a head cried out, "Kaor, Vor Daj!" It was Four-million-eight himself.

"Kaor, Tor-dur-bar!" I replied. "I am glad to see you again."

"Don't forget that you have one friend in Morbus," he said. "Soon I shall have a new body, and then if you need me I shall be ready."

"There is a hormad of unusual intelligence," said Ras Thavas. "I shall have to keep an eye on him."

"You should give such a brain as mine a fine-looking body," said Tor-dur-bar. "I should like to be as handsome as Vor Daj or his friend." "We shall see," said Ras Thavas, and then he leaned close and whispered to the head, "Say no more about it now. Just trust me."

"How long will it take to grow a new body for Tor-dur-bar?" John Carter asked.

"Nine days; but it may be a body he can't use, and then it will have to be done over again. I have accomplished much, but I still cannot control the development of these bodies or any part of them. Ordinarily his head will grow a body. It might be a body so malformed as to be useless, or it might be just a part of a body or even another head. Some day I shall be able to control this. Some day I shall be able to create perfect humans."

"If there is an Almighty God he may resent this usurpation of his prerogatives," remarked The Warlord with a smile.

"The origin of life is an obscure mystery," said Ras Thavas, "and there is quite as much evidence to indicate that it was the result of accident as there is to suggest that it was planned by a supreme being. I understand that the scientists of your Earth believe that all life on that planet was evolved from a very low form of animal life called amoeba, a microscopic nucleated mass of protoplasm without even a rudimentary form of consciousness or mental life. An omnipotent creator could just as well have produced the highest conceivable form of life in the first place-a perfect creature-whereas no existing life on either planet is perfect or even approximates perfection.

"Now, on Mars, we hold to a very different theory of creation and evolution. We believe that as the planet cooled chemicals combined to form a spore which was the basis of vegetable life from which, after countless ages, the Tree of Life grew and flourished, perhaps in the center of the Valley Dor twenty-three million years ago, as some believe, perhaps elsewhere. For countless ages the fruit of this tree underwent the gradual changes of evolution, passing by degrees from true plant life to a combination of plant and animal. In the first stages, 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 perception 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. At length, the fruit upon the tree consisted of tiny plant men, such as may now be found reproduced in huge size 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 foot in diameter, divided by double partition walls into four sections. In one section grew the plant man, in another a six-legged worm, in the third the progenitor of the white ape, and in the fourth the primeval human of Barsoom.

"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, these imprisoned creatures were scattered far and wide over the surface of the planet. For ages they lived their long lives within their hard shells, hopping and skipping hither and thither, falling into the rivers, lakes, and seas which then existed upon the surface of Barsoom, to be still further spread across the face of the new world. Countless billions died before the first human broke through his prison walls into the light of day.
