Tarzan looked in the direction that the other pointed and saw a mighty, flat-topped peak in the distance, directly above which low clouds were reflecting a dull red light. "So that is Xarator!" he remarked. "And Thenar is directly east of it?"
"Yes," replied Valthor; "which means that Onthar must be just below the edge of this plateau, almost directly in front of us. Come!"
The two walked quickly over the level, grassy ground for a mile or two to come at length to the edge of the plateau beyond which, and below them, stretched a wide valley.
"We are almost at the southern end of Onthar," said Valthor. "There is Cathne, the city of gold. See it—in the bend of the river at this end of that forest? It is a rich city but its people are the enemies of my people."
Through the rain, Tarzan saw a walled city between a forest and a river. The houses were nearly all white, and there were many domes of dull yellow. The river, which ran between them and the city, was spanned by a bridge that was also a dull yellow color in the twilight of the late afternoon storm. Tarzan saw that the river extended the full length of the valley, a distance of fourteen or fifteen miles, being fed by smaller streams coming down out of the mountains. Also extending the length of the valley was what appeared to be a well-marked road. Near the center of the valley it branched, one fork following an affluent of the main stream with which it disappeared into the mouth of a canyon on the eastern side of the valley. Directly below them and extending to the northern extremity of Onthar was a level plain dotted with trees; across the river, a forest stretched from the farther bank to the steep hills that bounded Onthar on the east and southeast.
Tarzan's eyes wandered back to the city of Cathne. "Why do you call it the city of gold?" he asked.
"Do you not see the golden domes and the bridge of gold?" demanded Valthor.
"Are they covered with gold paint?" inquired Tarzan.
"They are covered with solid gold," replied Valthor. "The gold on some of the domes is an inch thick, and the bridge is built of solid blocks of gold."
Tarzan lifted his eyebrows. As he looked down upon this seemingly deserted and peaceful valley he could not but conjure another picture—a picture of what it would be if word of these vast riches were carried to the outside world, bringing the kindly beneficences of modern civilization and civilized men to Onthar. How the valley would hum and roar then with the sweet music of mill and factory! What a gorgeous spectacle would be painted against the African sky by tall chimneys spouting black smoke to hang like a sable curtain above the golden domes of Cathne!
