A woman crossed the way directly in front of it and the lion paid no attention to her, nor she to the lion. An instant later a little child ran after the woman and so close did he run before the lion that the beast was forced to turn out of its way a step to avoid colliding with the little one. The ape-man grinned and crossed quickly to the opposite side of the street, for his delicate senses indicated that at this point the breeze stirring through the city streets and deflected by the opposite wall would now blow from the lion toward him as the beast passed, whereas if he remained upon the side of the street upon which he had been walking when he discovered the carnivore, his scent would have been borne to the nostrils of the animal, and Tarzan was sufficiently jungle-wise to realize that while he might deceive the eyes of man and beast he could not so easily disguise from the nostrils of one of the great cats that he was a creature of a different species from the inhabitants of the city, the only human beings, possibly, that Numa was familiar with.
In him the cat would recognize a stranger, and, therefore, an enemy, and Tarzan had no desire to be delayed by an en-counter with a savage lion. His ruse worked successfully, the lion passing him with not more than a side glance in his direction.
He had proceeded for some little distance and had about reached a point where he judged he would find the street which led up from the city gate when, at an intersection of two streets, his nostrils caught the scent spoor of the girl. Out of a maze of other scent spoors the ape-man picked the familiar odor of the girl and, a second later, that of Smith-Oldwick.
He had been forced to accomplish it, however, by bending very low at each street intersection in repeated attention to his sandal wrappings, bringing his nostrils as close to the pave-ment as possible.
As he advanced along the street through which the two had been conducted earlier in the day he noted, as had they, the change in the type of buildings as he passed from a residence district into that portion occupied by shops and bazaars. Here the number of flares was increased so that they appeared not only at street intersections but midway between as well, and there were many more people abroad. The shops were open and lighted, for with the setting of the sun the intense heat of the day had given place to a pleasant coolness. Here also the number of lions, roaming loose through the thoroughfares, increased, and also for the first time Tarzan noted the idiosyn-crasies of the people.
Once he was nearly upset by a naked man running rapidly through the street screaming at the top of his voice. And again he nearly stumbled over a woman who was making her way in the shadows of one of the arcades upon all fours. At first the ape-man thought she was hunting for something she had dropped, but as he drew to one side to watch her, he saw that she was doing nothing of the kind -- that she had merely elected to walk upon her hands and knees rather than erect upon her feet. In another block he saw two creatures strug-gling upon the roof of an adjacent building until finally one of them, wrenching himself free from the grasp of the other, gave his adversary a mighty push which hurled him to the pavement below, where he lay motionless upon the dusty road. For an instant a wild shriek re-echoed through the city from the lungs of the victor and then, without an instant's hesitation, the fel-low leaped headfirst to the street beside the body of his victim. A lion moved out from the dense shadows of a door-way and approached the two bloody and lifeless things before him. Tarzan wondered what effect the odor of blood would have upon the beast and was surprised to see that the animal only sniffed at the corpses and the hot red blood and then lay down beside the two dead men.
He had passed the lion but a short distance when his atten-tion was called to the figure of a man lowering himself la-boriously from the roof of a building upon the east side of the thoroughfare. Tarzan's curiosity was aroused.
