“We must hide our canoes,” explained Ja, “for the Mezops of Luana are always at war with us and would steal them if they found them,” he nodded toward an island farther out at sea, and at so great a distance that it seemed but a blur hanging in the distant sky. The upward curve of the surface of Pellucidar was constantly revealing the impossible to the surprised eyes of the outer-earthly. To see land and water curving upward in the distance until it seemed to stand on edge where it melted into the distant sky, and to feel that seas and mountains hung suspended directly above one’s head required such a complete reversal of the perceptive and reasoning faculties as almost to stupefy one. No sooner had we hidden the canoe than Ja plunged into the jungle, presently emerging into a narrow but well-defined trail which wound hither and thither much after the manner of the highways of all primitive folk, but there was one peculiarity about this Mezop trail which I was later to find distinguished them from all other trails that I ever have seen within or without the earth. It would run on, plain and clear and well defined to end suddenly in the midst of a tangle of matted jungle, then Ja would turn directly back in his tracks for a little distance, spring into a tree, climb through it to the other side, drop onto a fallen log, leap over a low bush and alight once more upon a distinct trail which he would follow back for a short distance only to turn directly about and retrace his steps until after a mile or less this new pathway ended as suddenly and mysteriously as the former section. Then he would pass again across some media which would reveal no spoor, to take up the broken thread of the trail beyond. As the purpose of this remarkable avenue dawned upon me I could not but admire the native shrewdness of the ancient progenitor of the Mezops who hit upon this novel plan to throw his enemies from his track and delay or thwart them in their attempts to follow him to his deep-buried cities. To you of the outer earth it might seem a slow and tortuous method of traveling through the jungle, but were you of Pellucidar you would realize that time is no factor where time does not exist. So labyrinthine are the windings of these trails, so varied the connecting links and the distances which one must retrace one’s steps from the paths’ ends to find them that a Mezop often reaches man’s estate before he is familiar even with those which lead from his own city to the sea. In fact three-fourths of the education of the young male Mezop consists in familiarizing himself with these jungle avenues, and the status of an adult is largely determined by the number of trails which he can follow upon his own island. The females never learn them, since from birth to death they never leave the clearing in which the village of their nativity is situated except they be taken to mate by a male from another village, or captured in war by the enemies of their tribe.
