A short distance beyond the point at which they had sur-rounded 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 em-brasures. Beyond the wall rose the domes of several struc-tures 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. The architecture of the wall itself was of uncompromising simplicity. It was of a cream shade and appeared to be plastered and painted. At its base was a line of well-tended shrubs and at some distance towards its eastern extremity it was vine covered to the top.
As he stood in the shadow of the trail, his keen eyes taking in every detail of the picture before him, he became aware of the approach of a party in his rear and there was borne to him the scent of the man and the lions whom he had so readily escaped. Taking to the trees Tarzan moved a short distance to the west and, finding a comfortable crotch at the edge of the forest where he could watch the trail leading through the gardens to the city gate, he awaited the return of his would-be captors. And soon they came -- the strange man followed by the pack of great lions. Like dogs they moved along behind him down the trail among the gardens to the gate.
Here the man struck upon the panels of the door with the butt of his spear, and when it opened in response to his signal he passed in with his lions. Beyond the open door Tarzan, from his distant perch, caught but a fleeting glimpse of life within the city, just enough to indicate that there were other human creatures who abode there, and then the door closed.
Through that door he knew that the girl and the man whom he sought to succor had been taken into the city. What fate lay in store for them or whether already it had been meted out to them he could not even guess, nor where, within that forbidding wall, they were incarcerated he could not know.
But of one thing he was assured: that if he were to aid them he could not do it from outside the wall. He must gain entrance to the city first, nor did he doubt, that once within, his keen senses would eventually reveal the whereabouts of those whom he sought.
The low sun was casting long shadows across the gardens when Tarzan saw the workers returning from the eastern field.
A man came first, and as he came he lowered little gates along the large ditch of running water, shutting off the streams that had run between the rows of growing plants; and behind him came other men carrying burdens of fresh vegetables in great woven baskets upon their shoulders. Tarzan had not realized that there had been so many men working in the field, but now as he sat there at the close of the day he saw a procession filing in from the east, bearing the tools and the produce back into the city.
And then, to gain a better view, the ape-man ascended to the topmost branches of a tall tree where he overlooked the nearer wall. From this point of vantage he saw that the city was long and narrow, and that while the outer walls formed a perfect rectangle, the streets within were winding. Toward the center of the city there appeared to be a low, white building around which the larger edifices of the city had been built, and here, in the fast-waning light, Tarzan thought that between two buildings he caught the glint of water, but of that he was not sure. His experience of the centers of civiliza-tion naturally inclined him to believe that this central area was a plaza about which the larger buildings were grouped and that there would be the most logical place to search first for Bertha Kircher and her companion.
And then the sun went down and darkness quickly en-veloped the city -- a darkness that was accentuated for the ape-man rather than relieved by the artificial lights which immediately appeared in many of the windows visible to him.
