into the pain-dulled eyes of the panthan.  With a quick step he crossed to the side of the dead warrior and dragged him from his mount.  With equal celerity he stripped him of his harness and his arms, and tearing off his own, donned the regalia of the dead man.  Then he hastened back to the room in which he had been trapped, for there he had seen that which he needed to make his disguise complete.  In a cabinet he found them—­pots of paint that the old taxidermist had used to place the war-paint in its wide bands across the cold faces of dead warriors.

A few moments later Gahan of Gathol emerged from the room a warrior of Manator in every detail of harness, equipment, and ornamentation.  He had removed from the leather of the dead man the insignia of his house and rank so that he might pass, with the least danger of arousing suspicion, as a common warrior.

To search for Tara of Helium in the vast, dim labyrinth of the pits of O-Tar seemed to the Gatholian a hopeless quest, foredoomed to failure.  It would be wiser to seek the streets of Manator where he might hope to learn first if she had been recaptured and, if not, then he could return to the pits and pursue the hunt for her.  To find egress from the maze he must perforce travel a considerable distance through the winding corridors and chambers, since he had no idea as to the location or direction of any exit.  In fact, he could not have retraced his steps a hundred yards toward the point at which he and Tara had entered the gloomy caverns, and so he set out in the hope that he might find by accident either Tara of Helium or a way to the street level above.

For a time he passed room after room filled with the cunningly preserved dead of Manator, many of which were piled in tiers after the manner that firewood is corded, and as he moved through corridor and chamber he noticed hieroglyphics painted upon the walls above every opening and at each fork or crossing of corridors, until by observation he reached the conclusion that these indicated the designations of passageways, so that one who understood them might travel quickly and surely through the pits; but Turan did not understand them.  Even could he have read the language of Manator they might not materially have aided one unfamiliar with the city; but he could not read them at all since, though there is but one spoken language upon Barsoom, there are as many different written languages as there are nations.  One thing, however, soon became apparent to him—­the hieroglyphic of a corridor remained the same until the corridor ended.

It was not long before Turan realized from the distance that he had traveled that the pits were part of a vast system undermining, possibly, the entire city.  At least he was convinced that he had passed beyond the precincts of the palace.  The corridors and chambers varied in appearance and architecture from time to time.  All were lighted, though usually quite dimly, with radium bulbs.  For a long time
