Mungo Park, The Journal of a Mission to the Interior of Africa…
“ May 5th.—Paid six bars of amber to the Mumbo Jumbo boys, and set out for Jindey early in the morning. Found this day's travelling very difficult; many of the asses refused to go on; and we were forced to put their loads on the horses. We reached Jindey about noon. Purchased a bullock, and halted the 6th; fearing, if we attempted to proceed, we should be forced to leave some of our loads in the woods. [Footnote: For a description of Mumbo Jumbo, see Park's Travels, p. 39.] ”
