23/32 The Franks are accustomed, as I have already stated, to take filtered water with them. When the supply becomes exhausted, they have only to put a few kernels of apricots or almonds chopped small into a vessel of Nile-water to render it tolerably clear within the space of five or six hours. I learnt this art from an Arab woman during my voyage on the Nile. The ground consists every where of sand, and only becomes fruitful through the mud which the Nile leaves behind after its inundation. Thus the luxuriant vegetation here only commences after the waters of the Nile have retired. |
