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."

CHAPTER V. THE JUDGEMENT OF THE JEDS

Janai, the girl from Amhor, sat apart. Her situation seemed to me pathetic in the extreme-a lone woman incarcerated with seven strange men in a city of hideous enemies. We red men of Barsoom are naturally a chivalrous race; but men are men, and I knew nothing of the five whom we had found here. As long as John Carter and I remained her fellow prisoners she would be safe; that I knew, and I thought that if she knew it, any burden of apprehension she might be carrying would be lightened.

As I approached her, with the intention of entering into conversation with her, the officer who had questioned us in the guardroom entered the compound with two other officers and several hormads. They gathered us together, and the two officers accompanying the officer of the guard looked us over. "Not a bad lot," said one.

The other shrugged. "The jeds will take the best of them, and Ras Thavas will grumble about the material he is getting. He always does."

"They don't want the girl, do they?" asked the officer of the guard.

"Our orders were to bring the prisoners," replied one of the others.

"I should like to keep the girl," said the officer of the guard.

"Who wouldn't?" demanded the other with a laugh.
