Numa, the lion, can run swiftly for a short distance, but he lacks endurance. For the period of an ordinary charge he can cover the ground with greater rapidity possibly than any other creature in the world. Tarzan, on the other hand, could run at great speed for long distances, though never as rapidly as Numa when the latter charged.
The question of his fate, then, rested upon whether, with his start he could elude Numa for a few seconds; and, if so, if the lion would then have sufficient stamina remaining to pursue him at a reduced gait for the balance of the distance to the wall.
Never before, perhaps, was staged a more thrilling race, and yet it was run with only the moon and stars to see. Alone and in silence the two beasts sped across the moonlit clearing. Numa gained with appalling rapidity upon the fleeing man, yet at every bound Tarzan was nearer to the vine-clad wall. Once the ape-man glanced back. Numa was so close upon him that it seemed inevitable that at the next bound he should drag him down; so close was he that the ape-man drew his knife as he ran, that he might at least give a good account of himself in the last moments of his life.
But Numa had reached the limit of his speed and endurance. Gradually he dropped behind but he did not give up the pursuit, and now Tarzan realized how much hinged upon the strength of the untested vines.
If, at the inception of the race, only Goro and the stars had looked down upon the contestants, such was not the case at its finish, since from an embrasure near the summit of the wall two close-set black eyes peered down upon the two. Tarzan was a dozen yards ahead of Numa when he reached the wall. There was no time to stop and institute a search for sturdy stems and safe handholds. His fate was in the hands of chance and with the realization he gave a final spurt and running catlike up the side of the wall among the vines, sought with his hands for something that would sustain his weight. Below him Numa leaped also.
Chapter XVIII
Among the Maniacs
As the lions swarmed over her protectors, Bertha Kircher shrank back in the cave in a momentary paralysis of fright super-induced, perhaps, by the long days of terrific nerve strain which she had undergone.
Mingled with the roars of the lions had been the voices of men, and presently out of the confusion and turmoil she felt the near presence of a human being, and then hands reached forth and seized her. It was dark and she could see but little, nor any sign of the English officer or the ape-man. The man who seized her kept the lions from her with what appeared to be a stout spear, the haft of which he used to beat off the beasts. The fellow dragged her from the cavern the while he shouted what appeared to be commands and warnings to the lions.
