Frank was not there, but a messenger was waiting with a letter from him. It briefly told the incidents of his journey from Afuddo to Foueira, and said that he thought best to remain at Foueira, to make certain repairs to the packages which were in his care, and had become injured on the way, and also to keep the porters in readiness for their departure to the south. Besides, if he went to the falls and returned to Foueira he would be obliged to go twice over the same road. He preferred to hear of the journey from the lips of Doctor Bronson and his cousin, rather than to make it himself, and he hoped they would think his decision a proper one. Of course, his action was approved without hesitation, as his absence from the fort might endanger the safety of their supplies, and there might be difficulty in having the requisite number of porters when wanted, if they were not kept steadily under control. Frank had taken the precaution to send guides that could conduct them to Foueira, a sufficient number of porters for carrying their baggage, and their saddle-horses, in charge of faithful grooms. Everything was unloaded from the steamer and piled on the bank of the river. It was within a couple of hours of sunset when the work was completed, and therefore Doctor Bronson determined not to move forward till the next day, when they would make an early start. The proper rewards were distributed to the officers and crew of the _Khedive_, and the Doctor and his nephew slept on board for the last time. They were roused before daylight by the faithful Ali, though they really had no occasion to be called, as both were wide-awake when the youth rapped on the doors of their cabins. The excitement of ending the lake voyage and again returning to land travel had given Fred a night of wakefulness, and it is possible that the same causes had had their effect on his more experienced companion. The sun was just peering above the horizon when the caravan was ready to move. As the head of the column of porters turned into the path that led along the bank of the river the steamer cast off the lines that had held her to the shore and turned down the stream, on her return to the point of departure. There was a general hurrahing on shore and on the boat, in token of farewell. As the _Khedive_ disappeared around a bend of the river our friends mounted their horses, and a few minutes later were once more in the depths of the African forest.
