They were in a far more important part of the city, passing better houses, some with fair gardens; palm and mimosa trees overtopped walls. Here and there the houses had rough balconies, and he caught a glimpse of the Mahdi's tomb, a white-topped domed building looking like a gigantic egg set on end, with four small ones to form corners, some attempt at ornamentation, and for apex what appeared to be a great gilded spear thrust through a couple of brass balls. To his great surprise they passed a busy marketplace and rough-looking shops, the dwellings of traders and makers of horse trappings and camel saddles; others displayed cotton fabrics, some even with ornamentations of silk; then makers of brass work, swords, and spears with the round shields carried by so many of the fighting men; and as they rode on through crowds of busy people he found that his companion was evidently noting his surprise and ready to smile with satisfaction at the interest he displayed. In his other excursions he and his companions had been the observed of all, and at every turn those they passed had turned to gaze, generally with scowls, at them and their protecting guard, and he had often felt that it was to the latter that they owed their safety. But now it was different: his black face and the company he was in made him seem one of the people, so that his appearance caused no surprise, and he was able to ride on perfectly unnoticed by the common folk and the many armed, overbearing, mounted and pacing warriors they passed. It was a novel and a wonderfully interesting scene as he hastily noticed how plain it was that he was riding through a conquered city in which the tribes from far south were displaying at every turn their contempt for and insolence to the humbled people they had mastered, and over whom they ruled by the sword and spear. He noted, too, the difference in type of feature, darkness of skin, and dress, between the various tribes, all of whom, however, were at one in their bullying aspect and overbearing way towards the humbled natives among whom they had taken up their residence; and hence it was that for the time being Frank had it forced upon him by the servile actions and harried ways of the men who stepped aside to let him and his companion pass, that he was looked upon as a member of one of the conquering race--one of the feared, instead of the contemned.
