Soon afterwards Glen reached the valley, which was apparently about half a mile broad. On its farther side was a line of shadow blacker than the rest. It might be timber. With tottering footsteps the boy staggered towards it. As his feet touched a patch of grass he could have knelt and kissed it, but at the same instant he heard the most blessed sound on earth, the trickling of a rivulet. He fell as he reached it, and plunged his head into the life-giving water. It was warm and strongly impregnated with sulphur; but never had he tasted anything so delicious, nor will he ever again.
