Next to them rode Sherif Mohammed Ali abu Sharrain, an old patriarch with a long, curling grey beard and an upright carriage of himself. His three hundred riders were Ashraf, of the Aiaishi (Juheina) stock, known Sherifs, but only acknowledged in the mass, since they had not inscribed pedigrees. They wore rusty-red tunics henna-dyed, under black cloaks, and carried swords. Each had a slave crouched behind him on the crupper to help him with rifle and dagger in the fight, and to watch his camel and cook for him on the road. The slaves, as befitted slaves of poor masters, were very little dressed. Their strong, black legs gripped the camels’ woolly sides as in a vice, to lessen the shocks inevitable on their bony perches, while they had knotted up their rags of shirts into the plaited thong about their loins to save them from the fouling of the camels and their staling on the march. Semna water was medicinal, and our animals’ dung flowed like green soup down their hocks that day.
