But the Sudanese were worried at the dog’s arrival; the two camel-drivers drew Chamis to one side and began to talk to him in a worried and excited manner:

“Idris brought this dog here,” cried Gebhr; “but how was he able to find his way to the children, for they came to Gharak by train?”

“Probably he followed the tracks of the camels,” answered Chamis.

“That is bad. Any one seeing him with us will mark our caravan, and will be able to show which road we have taken. By all hazards we must get rid of him!”

“But how?” asked Chamis.

“Here’s a gun—take it and put a bullet in his head.”

“It is true we have a gun; but I don’t know how to fire it. Perhaps you do.”

Chamis might have been able to fire it off in case of necessity, for Stasch had often opened and shut the lock of the gun in his presence; but his sympathy was aroused by the dog, which he had grown to like, even before the arrival of the children in Medinet. Besides, he knew very well that the two Sudanese had no idea how to use a gun of the newest pattern, and that they would not take the trouble to find out.

“If you are unable to do it,” he said with a cunning smile, “then no one but this little Christian will be able to kill the dog; but this gun might go off several times in succession, and so I do not advise you to give it into his hands.”

“Heaven forbid!” answered Idris. “He would shoot us down like quail.”
