Feeling about, he discovered that he was in a narrow corridor which he followed cautiously for a few yards to be brought up suddenly by what appeared to be a ladder across the passageway. He felt of the obstruction carefully with his hands until he was assured that it was indeed a ladder and that a solid wall was just beyond it, ending the corridor. Therefore, as he could not go forward and as the ladder ended at the floor upon which he stood, and as he did not care to retrace his steps, there was no alternative but to climb upward, and this he did, his pistol ready in a side pocket of his blouse.
He had ascended but two or three rungs when his head came suddenly and painfully in contact with a hard surface above him. Groping about with one hand over his head he discovered that the obstacle seemed to be the covering to a trap door in the ceiling which, with a little effort, he succeeded in raising a couple of inches, revealing through the cracks the stars of a clear African night.
With a sigh of relief, but with unabated caution, he gently slid the trapdoor to one side far enough to permit him to raise his eyes above the level of the roof. A quick glance assured him that there was none near enough to observe his movements, nor, in fact, as far as he could see, was anyone in sight.
Drawing himself quickly through the aperture he replaced the cover and endeavored to regain his bearings. Directly to the south of him the low roof he stood upon adjoined a much loftier portion of the building, which rose several stories above his head. A few yards to the west he could see the flickering light of the flares of a winding street, and toward this he made his way.
From the edge of the roof he looked down upon the night life of the mad city. He saw men and women and children and lions, and of all that he saw it was quite evident to him that only the lions were sane. With the aid of the stars he easily picked out the points of the compass, and following carefully in his memory the steps that had led him into the city and to the roof upon which he now stood, he knew that the thoroughfare upon which he looked was the same along which he and Bertha Kircher had been led as prisoners earlier in the day.
If he could reach this he might be able to pass undetected in the shadows of the arcade to the city gate. He had already given up as futile the thought of seeking out the girl and attempting to succor her, for he knew that alone and with the few remaining rounds of ammunition he possessed, he could do nothing against this city-full of armed men. That he could live to cross the lion-infested forest beyond the city was doubtful, and having, by some miracle, won to the desert beyond, his fate would be certainly sealed; but yet he was consumed with but one desire—to leave behind him as far as possible this horrid city of maniacs.
He saw that the roofs rose to the same level as that upon which he stood unbroken to the north to the next street intersection. Directly below him was a flare. To reach the pavement in safety it was necessary that he find as dark a portion of the avenue as possible. And so he sought along the edge of the roofs for a place where he might descend in comparative concealment.
He had proceeded some little way beyond a point where the street curved abruptly to the east before he discovered a location sufficiently to his liking. But even here he was compelled to wait a considerable time for a satisfactory moment for his descent, which he had decided to make down one of the pillars of the arcade. Each time he prepared to lower himself over the edge of the roofs, footsteps approaching in one direction or another deterred him until at last he had almost come to the conclusion that he would have to wait for the entire city to sleep before continuing his flight.
But finally came a moment which he felt propitious and though with inward qualms, it was with outward calm that he commenced the descent to the street below.
When at last he stood beneath the arcade he was congratulating himself upon the success that had attended his efforts up to this point when, at a slight sound behind him, he turned to see a tall figure in the yellow tunic of a warrior confronting him.

Out of the Niche
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 Wamabos.
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
