Numa, the lion, growled futilely in baffled rage as he slipped back to the ground at the foot of the wall after his unsuccessful attempt to drag down the fleeing ape-man. He poised to make a second effort to follow his escaping quarry when his nose picked up a hitherto unnoticed quality in the scent spoor of his intended prey. Sniffing at the ground that Tarzan's feet had barely touched, Numa's growl changed to a low whine, for he had recognized the scent spoor of the man-thing that had rescued him from the pit of the Wama-bos.
What thoughts passed through that massive head? Who may say? But now there was no indication of baffled rage as the great lion turned and moved majestically eastward along the wall. At the eastern end of the city he turned toward the south, continuing his way to the south side of the wall along which were the pens and corrals where the herbivorous flocks were fattened for the herds of domesticated lions within the city. The great black lions of the forest fed with almost equal impartiality upon the flesh of the grass-eaters and man. Like Numa of the pit they occasionally made excursions across the desert to the fertile valley of the Wamabos, but principally they took their toll of meat from the herds of the walled city of Herog, the mad king, or seized upon some of his luckless subjects.
Numa of the pit was in some respect an exception to the rule which guided his fellows of the forest in that as a cub he had been trapped and carried into the city, where he was kept for breeding purposes, only to escape in his second year. They had tried to teach him in the city of maniacs that he must not eat the flesh of man, and the result of their schooling was that only when aroused to anger or upon that one occasion that he had been impelled by the pangs of hunger, did he ever at-tack man.
The animal corrals of the maniacs are protected by an outer wall or palisade of upright logs, the lower ends of which are imbedded in the ground, the logs themselves being placed as close together as possible and further reinforced and bound together by withes. At intervals there are gates through which the flocks are turned on to the grazing land south of the city during the daytime. It is at such times that the black lions of the forest take their greatest toll from the herds, and it is infrequent that a lion attempts to enter the corrals at night.
But Numa of the pit, having scented the spoor of his bene-factor, was minded again to pass into the walled city, and with that idea in his cunning brain he crept stealthily along the outer side of the palisade, testing each gateway with a padded foot until at last he discovered one which seemed insecurely fastened. Lowering his great head he pressed against the gate, surging forward with all the weight of his huge body and the strength of his giant sinews -- one mighty effort and Numa was within the corral.
The enclosure contained a herd of goats which immediately upon the advent of the carnivore started a mad stampede to the opposite end of the corral which was bounded by the south wall of the city. Numa had been within such a corral as this before, so that he knew that somewhere in the wall was a small door through which the goatherd might pass from the city to his flock; toward this door he made his way, whether by plan or accident it is difficult to say, though in the light of ensuing events it seems possible that the former was the case.
To reach the gate he must pass directly through the herd which had huddled affrightedly close to the opening so that once again there was a furious rush of hoofs as Numa strode quickly to the side of the portal. If Numa had planned, he had planned well, for scarcely had he reached his position when the door opened and a herder's head was projected into the enclosure, the fellow evidently seeking an explana-tion of the disturbance among his flock. Possibly he discov-ered the cause of the commotion, but it is doubtful, for it was dark and the great, taloned paw that reached up and struck downward a mighty blow that almost severed his head from his body, moved so quickly and silently that the man was dead within a fraction of a second from the moment that he opened the door, and then Numa, knowing now his way, passed through the wall into the dimly lighted streets of the city be-yond.
Smith-Oldwick's first thought when he was accosted by the figure in the yellow tunic of a soldier was to shoot the man dead and trust to his legs and the dimly lighted, winding streets to permit his escape, for he knew that to be accosted was equivalent to recapture since no inhabitant of this weird city but would recognize him as an alien. It would be a simple thing to shoot the man from the pocket where the pistol lay without drawing the weapon, and with this purpose in mind the Englishman slipped his hands into the side pocket of his blouse, but simultaneously with this action his wrist was seized in a powerful grasp and a low voice whispered in English:
"Lieutenant, it is I, Tarzan of the Apes."The relief from the nervous strain under which he had been laboring for so long, left Smith-Oldwick suddenly as weak as a babe, so that he was forced to grasp the ape-man's arm for support -- and when he found his voice all he could do was to repeat: "You? You? I thought you were dead!""No, not dead," replied Tarzan, "and I see that you are not either. But how about the girl?""I haven't seen her," replied the Englishman, "since we were brought here. We were taken into a building on the plaza close by and there we were separated. She was led away by guards and I was put into a den of lions. I haven't seen her since.""How did you escape?" asked the ape-man.
