For some time the boat floated in silence. There could be heard only the grating of the oars on the boat's edges and once in a while a splash of water by a crocodile struck in the tail. Many of these ugly reptiles had swam down from the south to Khartûm, where they found an abundance of food, for the river teemed with corpses, not only of the people who were slaughtered after the capture of the city, but also of those who died of diseases which raged amidst the Mahdists and particularly among the slaves.
