ccomplishment of his ends, he now raised his spear and advanced
toward the other. This, evidently, was a language common to both,
for instantly the fellow raised his own weapon and at the same time
a low call broke from his lips, a call which instantly brought to
action every lion in the hitherto silent circle. A volley of roars
shattered the silence of the forest and simultaneously lions sprang
into view upon all sides as they closed in rapidly upon their
quarry. The man who had called them stepped back, his teeth bared
in a mirthless grin.

It was then that Tarzan first noticed that the fellow's upper canines
were unusually long and exceedingly sharp. It was just a flashing
glimpse he got of them as he leaped agilely from the ground and, to
the consternation of both the lions and their master, disappeared
in the foliage of the lower terrace, flinging back over his shoulder
as he swung rapidly away: "I am Tarzan of the Apes; mighty hunter;
mighty fighter! None in the jungle more powerful, none more cunning
than Tarzan!"

A short distance beyond the point at which they had surrounded him,
Tarzan came to the trail again and sought for the spoor of Bertha
Kircher and Lieutenant Smith-Oldwick. He found them quickly and
continued upon his search for the two. The spoor lay directly along
the trail for another half-mile when the way suddenly debouched
from the forest into open land and there broke upon the astonished
view of the ape-man the domes and minarets of a walled city.

Directly before him in the wall nearest him Tarzan saw a low-arched
gateway to which a well-beaten trail led from that which he had
been following. In the open space between the forest and the city
walls, quantities of garden stuff was growing, while before him
at his feet, in an open man-made ditch, ran a stream of water! The
plants in the garden were laid out in well-spaced, symmetrical rows
and appeared to have been given excellent attention and cultivation.
Tiny streams were trickling between the rows from the main ditch
before him and at some distance to his right he could see people
at work among the plants.

The city wall appeared to be about thirty feet in height, its
plastered expanse unbroken except by occasional embrasures. Beyond
the wall rose the domes of several structures and numerous minarets
dotted the sky line of the city. The largest and central dome
appeared to be gilded, while others were red, or blue, or yellow.
