“ The Danube, joined by the Iller just above the town and by the Blau just below, here becomes navigable, so that Ulm occupies the important commercial position of a terminal river-port. Hence there is water communication with the Neckar, and so to the Rhine and into the interior of France. The market for leather and cloth is important, and Ulm is famous for its vegetables (especially asparagus) , barley, beer, pipe-bowls and sweet cakes (Ulmer Zuckerbrot) . Bleaching, brewing and brass-founding are carried on, as well as a large miscellany of manufactures. ”
