The Dong people's skills with wood are put to use.
In 1854 there was a major outbreak of cholera in Soho, London. Nobody knew what caused cholera, but John Snow carefully mapped the location of every victim, (documented wonderfully in Stephen Johnson's book The Ghost Map) and figured out that the focus of the epidemic was a community pump. He removed the handle, forcing residents to get their water elsewhere, and the epidemic ended. It turned out that there was a leaky cesspit only a few feet away from the pump.
