"Which might have found the children."
"Perhaps. Let us hurry to them."
"Forward!"
The captain's orders resounded in one moment throughout the camp. The Zanzibarians sprang up suddenly on their feet. Soon torches were lit. Glenn in reply to the distant signal directed that a few rockets, one after the other, be sent up; and afterwards that the salvo of rifle shots be continued. Before a quarter of an hour elapsed the whole camp was on the way.
From the distance shots replied. There was no doubt that this was some kind of European caravan, appealing, from unknown reasons, for help.
The captain and the doctor raced forward, swept alternately by fear and hope. Would they find the children or would they not? The doctor said in his soul that, if not, they in the further journey could seek only for their remains amid those terrible heather-bushes.
After a half-hour one of those knobs, of which they had spoken before, obstructed the further view of the friends. But they were already so near that they heard distinctly the clatter of a horse's hoofs. In a few minutes, and on the top of the elevation, appeared a rider, holding before him a white object.
"Torches up," commanded Glenn.
In the same moment the rider brought his horse into the circle of light.
"Water! Water!"
