et 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 pavement 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 idiosyncrasies 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
struggling 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 fellow leaped headfirst
to the street beside the body of his victim. A lion moved out from
the dense shadows of a doorway 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
