"I have been too busy to fall in love," he replied good-naturedly.

"You are not very busy now," suggested Fou-tan.

"I think I shall be a very busy man for the next few days trying to get you back to Pnom Dhek," he assured her.

Fou-tan was silent. It was so dark that he could scarcely see her. But he could feel her presence near him, and it seemed to exert as strong an influence upon him as might have physical contact. He had recognised the power of that indefinable thing called personality when he had talked with people and looked into their eyes; but he never had had it reach out through the dark and lay hold of him as though with warm fingers of flesh and blood, and King found the sensation most disquieting.

They lay in silence upon their beds of dry grasses, each occupied with his own thoughts. The heat of the jungle day was rising slowly from the narrow gorge, and a damp chill was replacing it. The absolute darkness which surrounded them was slightly mitigated in their immediate vicinity by an occasional flame rising from the embers of their dying fire as some drying twigs of their fuel ignited. King was thinking of the girl at his side, of the responsibility which her presence entailed, and of the duty that he owed to her and to himself. He tried not to think about her, but that he found impossible, and the more that she was in his mind the stronger became the realisation of the hold that she had obtained upon him; that the sensation that she animated within him was love seemed incredibly preposterous. He tried to assure himself that it was but an infatuation engendered by her beauty and propinquity, and he girded himself to conquer his infatuation that he might perform the duty that had devolved upon him in so impersonal a way that there might be no regret.

In order to fortify this noble decision he cast Fou-tan from his mind entirely and occupied himself with thoughts of his friends in far-away America. In retrospect he laughed and danced again with Susan Anne Prentice; he listened to her pleasant cultured voice and enjoyed once more the sweet companionship of the girl who was to him all that a beloved sister might have been; and then a little sigh came from the bed of grasses at his side, and the vision of Susan Anne Prentice faded into oblivion.

Again there was a long silence, broken only by the murmur of the tumbling stream.

"Gordon King!" It was just a whisper.

"What is it, Fou-tan?"

"I am afraid, Gordon King," said the girl. How like a little child in the dark she sounded. Before he could answer, there came the sound of a soft thud down the gorge and the rattle of loose earth falling from above.
