Ignaz Pallme, Travels in Kordofan (1844)
“ This description of auction is not carried on at a fixed place, for the auctioneer, bawling out the price last bid, presses through the crowd of human beings, and runs from place to place until an advance is made, whereupon he is obliged to return to the former bidder, and inform him that his offer has been superseded. It is very remarkable that these criers can always accurately find out the man who has made a bid for the article in question, and thus expressed a wished to become a purchaser, in the immense crowd. ”
