Jason had no means for determining how far they had travelled, or how long they had been upon their way, but he was sure that considerable outer earthly time must have elapsed since he had met the girl, when they came to a seemingly insurmountable obstacle, for already he had made considerable progress toward mastering her tongue and they were exchanging short sentences, much to Jana's delight, her merry laughter, often marking one of Jason's more flagrant errors in pronunciation or construction. And now they had come to a deep chasm with overhanging walls that not even Jana could negotiate. To Jason it resembled a stupendous fault that might have been caused by the subsidence of the mountain range for it paralleled the main axis of the range. And if this were true he knew that it might extend for hundreds of miles, effectually barring the way across the mountains by the route they were following. For a long time Jana sought a means of descent into the crevice. She did not want to turn to the left as that route might lead her eventually back to the canyon that she had descended when pursued by Skruk and his fellows and she well knew how almost unscalable were the perpendicular sides of this terrific gorge. Another thing, perhaps, which decided her against the left hand route was the possibility that in that direction they might again come in contact with the Phelians, and so she led Jason toward the right and always she searched for a way to the bottom of the rift. Jason realized that they were consuming a great deal of time in trying to cross, but he became also aware of the fact that time meant nothing in timeless Pellucidar. It was never a factor with which to reckon for the excellent reason that it did not exist, and when he gave the matter thought he was conscious of a mild surprise that he, who had been always a slave of time, so easily and naturally embraced the irresponsible existence of Pellucidar. It was not only the fact that time itself seemed not to matter but that the absence of this greatest of all task masters singularly affected one's outlook upon every other consideration of existence. Without time there appeared to be no accountability for one's acts since it is to the future that the slaves of time have learned to look for their reward or punishment. Where there is no time, there is no future. Jason Gridley found himself affected much as Tarzan had been in that the sense of his responsibility for the welfare of his fellows seemed deadened. What had happened to them had happened and no act of his could alter it. They were not there with him and so he could not be of assistance to them, and as it was difficult to visualize the future beneath an eternal noonday sun how might one plan ahead for others or for himself? Jason Gridley gave up the riddle with a shake of his head and found solace in contemplation of the profile of The Red Flower of Zoram.
