They had passed Assuan! Stas thought of this continually, and doubt that the pursuit would ever overtake them stole gradually into his soul. He knew, indeed, that not only Egypt proper, which ends at Wâdi Haifa, that is, at the Second Cataract, but the whole of Nubia was up to that time in the hands of the Egyptian Government, but he also understood that beyond Assuan and particularly Wâdi Haifa the pursuit would be more difficult and the commands of the Government would be executed carelessly. His only hope was that his father with Mr. Rawlinson, after making arrangements for the pursuit from Fayûm, would go to Wâdi Haifa by steamer, and there securing troops of the camel-corps, would endeavor to intercept the caravan from the south. The boy reasoned that if he were in their place he would do just this, and for that reason he assumed that his supposition was very probable.
He did not, however, abandon the thought of a rescue on his own account. The Sudânese wanted to have powder for the captured rifle and with this object decided to disjoin a score of the rifle cartridges, so he told them that he alone was able to do that, and that if any one of them should undertake the task unskilfully, the cartridge would explode in his fingers and tear off his hands. Idris, fearing English inventions and unknown things generally, determined finally to entrust the boy with this undertaking. Stas went at it willingly, hoping in the first place that the powerful English powder at the first shot would burst the old Arabian rifle to pieces, and, again, that he might be able to hide a few cartridges. In fact, he succeeded more easily than he expected. Apparently they watched him at the work, but the Arabs began at once to talk among themselves and soon they were more occupied with their conversation than with their supervision. Finally this loquacity and inbred carelessness permitted Stas to conceal in his bosom seven cartridges. Now all that was necessary was to secure the rifle.
The boy judged that beyond Wâdi Haifa, the Second Cataract, this would not be a very difficult matter as he foresaw that as they drew nearer to their destination the Arabs' vigilance would relax. The thought that he would have to kill the Sudânese, the Bedouins, and even Chamis, always caused him to shudder, but after the murder which the Bedouins had committed, he did not have any scruples. He said to himself that the defense, liberty, and life of Nell were involved, and in view of this the lives of his adversaries did not deserve any consideration, especially if they did not surrender and it came to a fight.
