"Your own illustration," he said finally, "proves the falsity of your theory." He dropped a fruit from his hand to the ground. "See," he said, "without support even this tiny fruit falls until it strikes something that stops it. If Pellucidar were not supported upon the flaming sea it too would fall as the fruit falls--you have proven it yourself!" He had me, that time--you could see it in his eye. It seemed a hopeless job and I gave it up, temporarily at least, for when I contemplated the necessity explanation of our solar system and the universe I realized how futile it would be to attempt to picture to Ja or any other Pellucidarian the sun, the moon, the planets, and the countless stars. Those born within the inner world could no more conceive of such things than can we of the outer crust reduce to factors appreciable to our finite minds such terms as space and eternity. "Well, Ja," I laughed, "whether we be walking with our feet up or down, here we are, and the question of greatest importance is not so much where we came from as where we are going now. For my part I wish that you could guide me to Phutra where I may give myself up to the Mahars once more that my friends and I may work out the plan of escape which the Sagoths interrupted when they gathered us together and drove us to the arena to witness the punishment of the slaves who killed the guardsman. I wish now that I had not left the arena for by this time my friends and I might have made good our escape, whereas this delay may mean the wrecking of all our plans, which depended for their consummation upon the continued sleep of the three Mahars who lay in the pit beneath the building in which we were confined." "You would return to captivity?" cried Ja. "My friends are there," I replied, "the only friends I have in Pellucidar, except yourself. What else may I do under the circumstances?" He thought for a moment in silence. Then he shook his head sorrowfully. "It is what a brave man and a good friend should do," he said; "yet it seems most foolish, for the Mahars will most certainly condemn you to death for running away, and so you will be accomplishing nothing for your friends by returning. Never in all my life have I heard of a prisoner returning to the Mahars of his own free will. There are but few who escape them, though some do, and these would rather die than be recaptured." "I see no other way, Ja," I said, "though I can assure you that I would rather go to Sheol after Perry than to Phutra. However, Perry is much too pious to make the probability at all great that I should ever be called upon to rescue him from the former locality."
