This thought filled Mr. Tarkowski with terror, but this energetic man, who had formerly been a soldier, soon composed himself, recalled vividly to his memory all that had happened, and tried to think of some means of rescuing the children.

“Fatima,” he reasoned, “had no cause to revenge herself on our children; so if they were carried off it was only to give them into Smain’s hands. There is no possibility of their being threatened with death, and in misfortune that is something; but, on the other hand, the road that lies before them may lead to their destruction.”

He told Mr. Rawlison what he thought, then he continued:

“Idris and Gebhr, savage and ignorant men, think that the hosts of the Mahdi are not far off, but the Mahdi has advanced as far as Khartum, which is about two thousand kilometers from here. This distance they would have to travel along the banks of the Nile; they can not leave this route, for if they do the camels and the people would die of thirst. Go immediately to Cairo and ask the Khedive to send telegrams to every military station and make a raid on both banks of the river. The sheiks on the banks must be offered a large reward for the capture of the kidnappers. Every one coming to the villages to get water must be held up. In this way Idris and Gebhr will surely fall into the hands of the law, and we will have our children once more.”

Mr. Rawlison had regained his composure.

“I will go,” he said. “These villains have forgotten that England’s army under Wolseley is now hastening to the aid of Gordon and will separate them from the Mahdi. They shall not escape. They can not escape! I will send a telegram to our minister at once and then I shall go. What do you intend to do?”

“I shall telegraph for leave of absence, and without waiting for a reply I shall follow in their footsteps along the Nile to Nubia, to direct the search.”

“Then we shall meet, for I also intend doing likewise from Cairo on.”

“All right! And now to work!”

“With God’s help!” answered Mr. Rawlison.
