In referring to a well at Ardericca, a place about 40 miles from ancient Susa, in Persia, Herodotus says :—" For from the well the\ " get bitumen, salt, and oil, procuring it in the way that I will now describe : they draw "with a swipe, and instead of a bucket they make use of the half of a wine-skin ; with " this the man dips and, after drawing, pours the liquid into a reservoir, wherefrom it " passes into another, and there takes three different shapes.
