“No, no, I cannot stay behind. Let me get the lantern,” she said feverishly, and quickly unhitched the lantern from its hook under the canvas “scherm,” at the same time picking up her rifle.

“This way,” said Webster, and they descended rapidly the slope leading to the river, from which there came a rippling noise strangely mysterious in the dark. The shaft of light swept around from left to right over rocks and ant-hills, and nodding bushes, and at every dark object they strained their eyes. Then there came a sound that chilled their blood: the noise of a body falling in the water, followed by a deep groan.

After the brilliant flash, the darkness closed in blacker than before, and when the echoes of the report had rolled away in the sullen mutterings down the valley the silence was the deeper. They waited long, then went on quickly to the river, where they stood above the rushes, looking at the gleam upon the dark water, and listening with pale faces and beating hearts to faint whisperings and gurgling noises.
