It was the slight rocking of the prahu that caused Barunda to look suddenly about to discover the reason for the disturbance. For a moment neither of the men apprehended the girl’s absence. Ninaka was the first to do so, and it was he who called loudly to the paddlers to bring the boat to a stop. Then they dropped down the river with the current, and paddled about above the gorge for half an hour. The moment that Virginia Maxon felt the waters close above her head she struck out beneath the surface for the shore upon the opposite side to that toward which she had dived into the river. She knew that if any had seen her leave the prahu they would naturally expect to intercept her on her way toward the nearest shore, and so she took this means of outwitting them, although it meant nearly double the distance to be covered. After swimming a short distance beneath the surface the girl rose and looked about her. Up the river a few yards she caught the phosphorescent gleam of water upon the prahu’s paddles as they brought her to a sudden stop in obedience to Ninaka’s command. Then she saw the dark mass of the war-craft drifting down toward her. Again she dove and with strong strokes headed for the shore. The next time that she rose she was terrified to see the prahu looming close behind her. The paddlers were propelling the boat slowly in her direction—it was almost upon her now—there was a shout from a man in the bow—she had been seen. Like a flash she dove once more and, turning, struck out rapidly straight back beneath the oncoming boat. When she came to the surface again it was to find herself as far from shore as she had been when she first quitted the prahu, but the craft was now circling far below her, and she set out once again to retrace her way toward the inky mass of shore line which loomed apparently near and yet, as she knew, was some considerable distance from her. As she swam, her mind, filled with the terrors of the night, conjured recollection of the stories she had heard of the fierce crocodiles which infest certain of the rivers of Borneo. Again and again she could have sworn that she felt some huge, slimy body sweep beneath her in the mysterious waters of this unknown river. Behind her she saw the prahu turn back up stream, but now her mind was suddenly engaged with a new danger, for the girl realized that the strong current was bearing her down stream more rapidly than she had imagined. Already she could hear the increasing roar of the river as it rushed, wild and tumultuous, through the entrance to the narrow gorge below her. How far it was to shore she could not guess, or how far to the certain death of the swirling waters toward which she was being drawn by an irresistible force; but of one thing she was certain, her strength was rapidly waning, and she must reach the bank quickly.
