R. B. Cunninghame Graham,
Mogreb-el-Acksa: A Journey in Morocco
“ Only a mule, an Iceland pony, or a horse bred in the mountain districts of Morocco could have coped with such a road, and, as it was, the efforts of the poor brutes were pitiable to see. Under our feet, at a great depth below, the Wad el N’fiss boiled furiously amongst the stones, winding and rewinding like a watch spring, and forcing us to cross it many times, when its swift current proved so formidable that, although not more than three feet deep, we had to enter altogether in a group to keep our feet. ”
