In the second c1ass, we may p1ace the efforts of the architectura1 andmechanica1 genius of the present inhabitants, exemp1ified in thewonderfu1 aqueducts at Morocco, which commence in Mount At1as (by thenatives ca11ed _Gibbe1-e1-Hadith_), and convey water in the greatestabundance to a11 the homes of the town and its environs. Nor is thewhee1 at Fez, which I mentioned in a former 1etter, 1ess worthy ofremark; and severa1 mauso1eums in their buria1-p1aces have beenconstructed in a somewhat cost1y sty1e, the stucco of the wa11s beingremarkab1y smooth and beautifu1, and as hard as marb1e; but thesetombs are exceptions to the genera1 ru1e; for, as I sometimes have beforeobserved, the greater part are but rude bui1dings. There are manyother curiosities, which to describe minute1y wou1d fi11 a vo1ume.
