Tarzan thought of Valthor and wondered if he had reached Athne in safety. He glanced back at Thudos and Gemnon. He had not spoken to them, but it was because of them that he was here. He might easily have escaped had he not determined to remain until he was certain that he could not aid these friends. Their case appeared hopeless, yet the ape-man had not given up hope.

At noon the procession stopped for lunch. The populace scattered about seeking the shade of the trees that dotted the plain and that had not already been selected by the Queen and the nobles. The lions were led into shade, where they lay down to rest. Warriors, always on the lookout for danger, stood guard about the temporary encampment. There was always danger on the Field of the Lions.

The halt was brief; in half an hour the cavalcade was on the march again. There was less talking now; silence and the great heat hung over the dusty column. The hills that bounded the valley upon the north were close, and soon they entered them, following a canyon upward to a winding mountain road that led into the hills above.

Presently the smell of sulphur fumes came plainly to the nostrils of the ape-man, and a little later the column turned the shoulder of a great mass of volcanic rock and came upon the edge of a huge crater. Far below, molten rock bubbled, sending up spurts of flame, geysers of steam, and columns of yellow smoke. The scene was impressive and awe-inspiring. Before Cathne, before Rome, before Athens, before Babylon, before Egypt, Xarator had towered in lonely majesty above the lesser peaks. Beside that mighty cauldron queen and noble shrank to pitiful insignificance though perhaps there was but one in that great throng that realized this. Tarzan stood with folded arms and bent head gazing down into the seething inferno until the Queen touched him on the shoulder. "What do you think of Xarator?" she asked.

He shook his head. "There are some emotions," he answered slowly, "for which no words have yet been coined."

"It was created by Thoos for the kings of Cathne," she explained proudly.

Tarzan made no reply; perhaps he was thinking that here again the lexicographers had failed to furnish words adequate to the occasion.

On either side of the royal party the people crowded close to the edge of the crater that they might miss nothing of what was about to transpire. The children laughed and played, or teased their mothers for the food that was being saved for the evening meal upon the return journey to Cathne.

Tarzan saw Thudos and Gemnon standing beside the chariot in which lay the still form of the victim. Of what emotions were passing within their minds none appeared through the masks of stern pride that sat upon their countenances, yet Tarzan well knew the suffering of their torn and bleeding hearts. He had not spoken to them once this day, for he had not had an opportunity to speak to them except in the presence of others; and whatever he might have to say to them must be for their ears only. He had not given up the hope of helping them, but he could not conceive that open and unnecessary familiarity with them at this time might accomplish anything more than to still further arouse the suspicions of Nemone and increase the watchfulness of all their enemies.

If Gemnon or Thudos noticed the neglect of their former friend and guest they gave no sign, for neither gave him any greater attention as he walked beside the chariot of the Queen a few paces in advance of them than they gave to the lions drawing the car to which they were secured. Their thoughts were upon the poor, dumb thing jolting upon the hard planks that formed the floor of the springless chariot bearing it to its doom. Not once had they seen the girl move, not once had she uttered a sound; and they hoped that she was either insensible or dead, for thus would she be saved the anguish of these last moments and Nemone be robbed of the essence of her triumph.
