In the second class, we may place the efforts of the architectural andmechanical genius of the present inhabitants, exemplified in thewonderful aqueducts at Morocco, which commence in Mount Atlas (by thenatives called _Gibbel-el-Hadith_), and convey water in the greatestabundance to all the houses of the city and its environs. Nor is thewheel at Fez, which I mentioned in a former letter, less worthy ofremark; and several mausoleums in their burial-places have beenconstructed in a somewhat costly style, the stucco of the walls beingremarkably smooth and beautiful, and as hard as marble; but thesetombs are exceptions to the general rule; for, as I have beforeobserved, the greater part are but rude buildings. There are manyother curiosities, which to describe minutely would fill a volume.
