“You forget,” he said, “that they are but thin air—figments of my brain. They will vanish, unscathed, when we have no further need for them. Praised be your first ancestor, redman, that you thought of this chance in time! It would never have occurred to me to imagine that I might wield the same power that brought me into existence.”

“You are right,” said Carthoris. “Still, I hate to leave them, though there is naught else to do,” and so the two turned from the courtyard, and making their way into one of the broad avenues, crept stealthily in the shadows of the building toward the great central plaza upon which were the buildings occupied by the green warriors when they visited the deserted city.

When they had come to the plaza’s edge Carthoris halted.

“Wait here,” he whispered. “I go to fetch thoats, since on foot we may never hope to escape the clutches of these green fiends.”

To reach the courtyard where the thoats were kept it was necessary for Carthoris to pass through one of the buildings which surrounded the square. Which were occupied and which not he could not even guess, so he was compelled to take considerable chances to gain the enclosure in which he could hear the restless beasts squealing and quarrelling among themselves.

Chance carried him through a dark doorway into a large chamber in which lay a score or more green warriors wrapped in their sleeping silks and furs. Scarce had Carthoris passed through the short hallway that connected the door of the building and the great room beyond it than he became aware of the presence of something or some one in the hallway through which he had but just passed.

He heard a man yawn, and then, behind him, he saw the figure of a sentry rise from where the fellow had been dozing, and stretching himself resume his wakeful watchfulness.

Carthoris realized that he must have passed within a foot of the warrior, doubtless rousing him from his slumber. To retreat now would be impossible. Yet to cross through that roomful of sleeping warriors seemed almost equally beyond the pale of possibility.

Carthoris shrugged his broad shoulders and chose the lesser evil. Warily he entered the room. At his right, against the wall, leaned several swords and rifles and spears—extra weapons which the warriors had stacked here ready to their hands should there be a night alarm calling them suddenly from slumber. Beside each sleeper lay his weapon—these were never far from their owners from childhood to death.

The sight of the swords made the young man’s palm itch. He stepped quickly to them, selecting two short-swords—one for Kar Komak, the other for himself; also some trappings for his naked comrade.
