about them. This knowledge may serve him well now, and John is pleased
to think he is in the hands of one so well informed.

In half an hour they have managed to learn an important fact. The
prisoners are in the main cavern. All escape is cut off by the presence
of numerous guards at the mouth of the mine, and they are watched
besides.

Mustapha, putting his knowledge of the place into good use, has led his
companion into a cleft where there is hardly room to crawl; but, as they
reach the end, they have a chance to gaze upon the interior where the
Arabs and Kabyles, the Moors and negroes, who battle under the free
banner of Bab Azoun, are assembled.

Eagerly John looks upon the face of Lady Ruth. His heart seems in his
throat, and he no longer can deceive himself regarding his true feelings
toward this young lady.

"What can we do?" he whispers to the Arab.

"Nothing but wait," is the reply.

John has a great fear tugging at his heart. On their way they have
discussed the situation, and Mustapha has related the habits of the Arab
desert outlaws. Should it appear that a rescue was imminent, it was
their habit to murder any prisoners.

Surely this is enough to arouse John's keenest fears. What if the French
forces do come and annihilate the robber host--if the prisoners share
their doom, what has been gained?
