Research: The Art of Travel

Found The Art of Travel, Sir Francis Galton, 1855, a book of advice based on his experiences in southwest Africa. I was looking up different kinds of pack/riding animals (“Now, it is to be noticed that men attach themselves to horses and asses, and in a lesser degree to mules and oxen, but they rarely make friends of camels.”), but was also amused by the figure showing a knot that you must never tie.
