How could such a city exist without markets or commerce?

My speculations were interrupted by our arrival before a small doorway in a blank wall. Sytor pounded on the door with the hilt of his sword, whereupon a small panel was opened and a face appeared.

"I am Sytor, Dwar of the 10th Utan, 1st Dar of the 3rd Jed's Guard. I bring prisoners to await the pleasure of the Council of the Seven Jeds."

"How many?" asked the man at the wicket.

"Three-two men and a woman."

The door swung open, and Sytor motioned us to enter. He did not accompany us. We found ourselves in what was evidently a guardroom, as there were about twenty hormad warriors there in addition to the officer who had admitted us, who, like the other officers we had seen, was a normal red man like ourselves. He asked us our names, which he entered in a book with other information such as our vocations and the cities from which we came; and it was during this questioning that I learned the name of the girl. She was Janai; and she said that she came from Amhor, a city about seven hundred miles north of Morbus. It is a small city ruled by a prince named Jal Had who has such a bad reputation that it has reached to far away Helium. That was about all that I knew about Amhor.

After he had finished questioning us, the officer directed one of the hormads to take us away; and we were led down a corridor to a large patio in which there were a number of red Martians. "You will stay here until you are sent for," said the hormad. "Do not try to escape." Then he left us.

"Escape!" said John Carter with a wry smile. "I have escaped from many places; and I can probably escape from this city, but escaping from the Toonolian Marshes is another matter. However, we shall see."

The other prisoners, for such they proved to be, approached us. There were five of them. "Kaor!" they greeted us. We exchanged names; and they asked us many questions about the outside world, as though they had been prisoners for years.

But they had not. The fact that Morbus was so isolated seemed to impart to them the feeling that they had been out of the world for a long time. Two of them were Phundahlians, one was from Toonol, one from Ptarth, and one from Duhor.

"For what purpose do they keep prisoners?" asked John Carter.

"They use some as officers to train and command their warriors," explained Pandar, one of the Phundahlians. "The bodies of others are used to house the brains of those of the hormads intelligent enough to serve in high places. The bodies of others go to the culture laboratories, where their tissue is used in the damnable work of Ras Thavas."

"Ras Thavas!" exclaimed The Warlord. "He is here in Morbus?"

"He is that-a prisoner in his own city, the servant of the hideous creatures he has created," replied Gan Had of Toonol.

"I don't follow you," said John Carter.

"After Ras Thavas was driven from his great laboratories by Vobis Kan, Jeddak of Toonol," explained Gan Had, "he came to this island to perfect a discovery he had been working on for years. It was the creation of human beings from human tissue. He had perfected a culture in which tissue grew continuously. The growth from a tiny particle of living tissue filled an entire room in his laboratory, but it was formless. His problem was to direct this growth. He experimented with various reptiles which reproduce certain parts of their bodies, such as toes, tails, and limbs, when they are cut off; and eventually he discovered the principle. This he has applied to the control of the growth of human tissue in a highly specialized culture. The result of these discoveries and experiments are the hormads. Seventy-five per cent of the buildings in Morbus are devoted to the culture and growth of these horrid creatures, which Ras Thavas turns out in enormous numbers.

"Practically all of them are extremely low in intelligence; but a few developed normal brains, and some of these banded together to take over the island and establish a kingdom of their own. On threat of death, they have compelled Ras Thavas to continue to produce these creatures in great numbers; for they have conceived a stupendous plan which is nothing less than to build up an army of millions of hormads and with them conquer the world, They will take Phundahl and Toonol first, and then gradually spread out over the entire surface of the globe."

"Amazing," said John Carter, "but I think they have reckoned without a full understanding of all the problems such an undertaking will involve. It is inconceivable, for instance, that Barsoom could feed such an army in the field; and this little island certainly could not feed the nucleus of such an army."

"There you are mistaken," replied Gan Had. "The food for the hormads is produced by means almost identical with those which produce them-a slightly different culture; that is all. Animal tissue grows with great rapidity in this culture, which can be carried along with an army in tanks, constantly providing sufficient food; and, because of its considerable water content, sufficient water."

"But can these half-humans hope to be victorious over well-trained, intelligent troops fitted for modern warfare?" I asked.

"I think so," said Pandar. "They will do it by their overwhelming numbers, their utter fearlessness, and the fact that it is necessary to decapitate them before they can be rendered hors de combat."

"How large an army have they?" inquired John Carter.

"There are several million hormads on the island. Their huts are scattered over the entire area of Morbus. It is estimated that the island can accommodate a hundred million of them; and Ras Thavas claims that he can march them into battle at the rate of two million a year, lose every one of them, and still have his original strength undepleted by as much as a single man. This plant turns them out in enormous quantities. A certain percentage are so grossly malformed as to be utterly useless. These are sliced into hundreds of thousands of tiny pieces that are dumped back into the culture vats, where they grow with such unbelievable rapidity that within nine days each has developed into a full-sized hormad, an amazing number of which have developed into something that can march and wield a weapon."

"The situation would appear serious but for one thing," said John Carter.

"And what is that?" asked Gan Had.

"Transportation. How are they going to transport such an enormous army?"

"That has been their problem, but they believe that Ras Thavas has now solved it. He has been experimenting for a long time with malagor tissue and a special culture medium. If he can produce these birds in sufficient quantities, the problem of transport will have been solved. For the fighting ships which they will need, they are relying on those they expect to capture when they take Phundahl and Toonol as the nucleus of a great fleet which will grow as their conquests take in more and larger cities."

The conversation was interrupted by the arrival of a couple of hormads carrying a vessel which contained animal tissue for our evening meal- a most unappetizing-looking mess.

The prisoner from Duhor, who, it seemed, had volunteered to act as cook, built a fire in the oven that formed a part of the twenty-foot wall that closed the only side of the patio that was not surrounded by portions of the building; and presently our dinner was grilling over a hot fire.

I could not contemplate the substance of our meal without a feeling of revulsion, notwithstanding the fact that I was ravenously hungry; and my mind was alive with doubts engendered by all that I had been listening to since entering the compound; so that I turned to Gan Had with a question. "Is this, by any chance, human tissue?" I asked.

He shrugged. "It is not supposed to be; but that is a question we do not even ask ourselves, for we must eat to live; and this is all that they bring us."
