Mungo Park, Life and Travels of Mungo Park
“ The city depends exclusively on trade, which is entirely in the hands of the Moors. The chief article of commerce is salt, which is dug out of the mines of Sahara; but other articles, both of European and native manufacture, are likewise sold. The goods are embarked for Jenne, and bartered for gold, slaves, and provisions. The city is surrounded with plains of moving sand. "The horizon is of a pale red. All is gloomy in nature. The deepest silence reigns—not the song of a single bird is heard." ”
