But nevertheless these two did, after a fashion, reflect the social environment to which he was accustomed and as he tried to answer Jana's question he could not but picture her seated at dinner with a company made up of such as these. Of course, Jana was a bully companion upon an adventure such as that in which they were engaged, but modern man cannot go adventuring forever in the Stone Age. If his eyes had carried any other message to Jana than that of friendly comradeship he felt sorry, for he realized that in fairness to her, as well as to himself, there could never be anything more than this between them. As Jason hesitated for a reply, the eyes of The Red Flower of Zoram searched his soul and slowly the half expectant smile faded from her lips. Perhaps she was a savage little barbarian of the Stone Age, but she was no fool and she was a woman. Slowly she drew her slender figure erect as she turned away from him and started back along the rim of the rift toward the great gorge through which she had descended from the higher peaks when Skruk and his fellows had been pursuing her. "Jana," he exclaimed, "don't be angry. Where are you going?" She stopped and with her haughty little chin in air turned a withering look back upon him across a perfect shoulder. "Go your way, jalok," she said, "and Jana will go hers." IX TO THE THIPDAR'S NEST Heavy clouds formed about the lofty peaks of the Mountains of the Thipdars--black, angry clouds that rolled down the northern slopes, spreading far to east and west. "The waters have come again," said Thoar. "They are falling upon Zoram. Soon they will fall here too." It looked very dark up there above them and presently the clouds swept out across the sky, blotting out the noonday sun. It was a new landscape upon which Tarzan looked--a sullen, bleak and forbidding landscape. It was the first time that he had seen Pellucidar in shadow and he did not like it. The effect of the change was strikingly apparent in Thoar and Tar-gash. They seemed depressed, almost fearful. Nor was it man alone that was so strangely affected by the blotting out of the eternal sunlight, for presently from the upper reaches of the mountains the lower animals came, pursuing the sunlight. That they, too, were strangely affected and filled with terror was evidenced by the fact that the carnivores and their prey trotted side by side and that none of them paid any attention to the three men. "Why do they not attack us, Thoar?" asked Tarzan. "They know that the water is about to fall," he replied, "and they are afraid of the falling water. They forget their hunger and their quarrels as they seek to escape the common terror." "Is the danger so great then?" asked the ape-man.
