For some time the two talked. Valthor told of his life in Athne. And as Valthor talked, the invisible sun sank ower into the west; heavy clouds, dark and ominous, hid the peaks to the north, settling low over the upper end of the valley. "I think we may start now," Valthor said.
"It will soon be dark."
Downward through a gully, the sides of which hid them from the city of Cathne , the two men made their way towards the floor of the valley. From the heavy storm clouds burst a flash of lightning followed by the roar of thunder; upon the upper end of the valley the storm god loosed his wrath; water fell in a deluge, wiping from their sight the hills beyond the storm.
By the time they reached level ground the storm was upon them and the gully they had descended a raging mountain torrent. The swift night had fallen; utter darkness surrounded them, darkness frequently broken by vivid flashes of lightning. The pealing of the constant thunder was deafening. The rain engulfed them in solid sheets like the waves of the ocean. It was, perhaps, the most terrific storm that either of these men had ever seen.
They could not converse; only the lightning prevented their becoming separated, as it alone permitted Valthor to keep his course across the grassy floor of the valley in the direction of the city of gold, where they would find the road that led to the Pass of the Warriors and on into the valley of Thenar.
Presently they came within sight of the lights of the city, a few dim lights framed by the casements of windows, and a moment later they were on the road and were moving northward against the full fury of the storm.
For miles they pitted their muscles against the Herculean strength of the storm god. The rage of the storm god seemed to rise against them, knowing no bounds, as though he was furious that these two puny mortals should pit their strength against his. Suddenly, as though in a last titanic effort to overcome them, the lightning burst into a rrizh ty blaze that illuminated the entire valley for seconds, the thunder crashed as it had never crashed before, and a mass of water fell that crushed the two men to earth.
As they staggered to their feet again, foot-deep water swirled about their legs; they stood in a broad, racing torrent that rushed past them towards the river. But in that last effort the storm god had spent his force. The rain ceased; through a rift in the dark clouds the moon looked down, perhaps in wonder, upon a drowned world, and Valthor led the way again towards the Pass of the Warriors. The last of the rainy season was over.
It is seven miles from the bridge of gold, that is the gateway to the city of Cathne , to the ford where the road to Thenar crosses the river. It required three hours for Valthor and Tarzan to cover the distance, but at last they stood at the river's bank.
A boiling flood confronted them, tearing down a widened river towards the city of Cathne . Valthor hesitated. "Ordinarily," he said to Tarzan, "the water is little more than a foot deep. It must be three feet deep now.
"And it will soon be deeper," commented the ape-man.
"Only a small portion of the storm waters have had time to reach this point from the hills and the upper valley. If we are going to cross tonight, we shall have to do it now.
"Very well," replied Valthor, "but follow me; I know the ford."
As the Athnean stepped into the water, the clouds closed again beneath the moon and plunged the world once more into darkness. As Tarzan followed he could scarcely see his guide ahead of him, and since Valthor knew the ford he moved more rapidly than the ape-man with the result that presently Tarzan could not see him at all, but he felt his way towards the opposite bank without thought of disaster.
The force of the stream was mighty, but mighty, too, are the thews of Tarzan of the Apes. The water, which Valthor had thought to be three feet in depth, was soon surging to the ape-man's waist, and then he missed the ford and stepped into a hole. Instantly the current seized him and swept him away; not even the giant muscles of Tarzan could cope with the might of the flood.
The Lord of the Jungle fought the swirling waters in an effort to reach the opposite shore, but in their embrace he was powerless.
Finding even his great strength powerless and weakening, Tarzan gave up the struggle to reach the opposite bank and devoted his efforts to keeping his nose above the surface of the angry flood. Even this was none too easy an accomplishment, as the rushing waters had a trick of twisting him about or turning him over. Often his head was submerged, and sometimes he floated feet first and sometimes head first, but he tried to rest his muscles as best he could against the time when some vagary of the torrent might carry him within reach of the bank upon one side or the other.
He knew that several miles below the city of Cathne the river entered a narrow gorge, for that he had seen from the edge of the plateau from which he had first viewed the valley of Onthar . Valthor had told him that beyond the gorge it tumbled in a mighty falls a hundred feet to the bottom of a rocky canyon. Should he not succeed in escaping the clutches of the torrent before it carried him into the gorge his doom was sealed, but Tarzan felt neither fear nor panic. His life had been in jeopardy often during his savage existence, yet he still lived.
He wondered what had become of Valthor. Perhaps he, too, was being hurtled along either above or helow him. But such was not the fact. Valthor had reached the opposite bank in safety and waited there air Tarzan. When the ape-man did not appear within a reasonable Time, the Athnean shouted his name aloud, but though he received no answer he was still not sure that Tarzan was not upon the opposite side of the river, the loud roaring of which might have drowned the sound of the voice of either.
Then Valthor decided to wait until daylight, rather than abandon his friend in a country with which he was entirely unfamiliar.
Through the long night he waited and, with the coming of dawn, eagerly scanned the opposite bank of the river, his slender hope for the safety of his friend dying when daylight failed to reveal any sign of him. Then, at last, he was convinced that Tarzan had been swept away to his death by the raging flood, and, with a heavy heart, he turned away from the river and resumed his interrupted journey towards the Pass of the Warriors and the valley of Thenar .
CHAPTER FIVE THE CITY OF GOLD
As Tarzan battled for his life in the swirling waters of the swollen river, he lost all sense of time; the seemingly interminable struggle against death might have been enduring without beginning, might endure without end, in so far as his numbed senses were concerned.
Turnings in the river cast him occasionally against one shore and then the other. Always, then, his hands reached up in an attempt to grasp something that might stay his mad rush towards the falls and death. At last success crowned his efforts-his fingers closed upon the stem of a heavy vine that trailed down the bank into the swirling waters, closed and held.
Hand over hand the man dragged himself out of the water and onto the bank, where he lay for several minutes; then he rose slowly to his feet, shook himself like some great lion, and looked about him in the darkness, trying to penetrate the impenetrable night. Faintly, as through shrubbery, he thought that he saw a light shining dimly in the distance. Where there was a light, there should be men. Tarzan moved cautiously toward it to investigate.
But a few steps from the river Tarzan encountered a wall, and when he was close to the wall he could no longer see the light. Reaching upward, he discovered that the top of the wail was still above the tips of his outstreched fingers—but walls which were made to keep one out also invited one to climb them.
