We were soon to know, however, for as we reached the edge of the pool directly above the thing, Xodar cried out a few words in a strange tongue. Immediately a hatch cover was raised from the surface of the object, and a black seaman sprang from the bowels of the strange craft.

Xodar addressed the seaman.

"Transmit to your officer," he said, "the commands of Dator Xodar. Say to him that Dator Xodar, with officers and men, escorting two prisoners, would be transported to the gardens of Issus beside the Golden Temple."

"Blessed be the shell of thy first ancestor, most noble Dator," replied the man. "It shall be done even as thou sayest," and raising both hands, palms backward, above his head after the manner of salute which is common to all races of Barsoom, he disappeared once more into the entrails of his ship.

A moment later an officer resplendent in the gorgeous trappings of his rank appeared on deck and welcomed Xodar to the vessel, and in the latter's wake we filed aboard and below.
