  • Variants survive today in slum-ridden megacities like Cairo, Mumbai, and Buenos Aires, but the epitome was early nineteenth-century London, where a scavenger army of tens of thousands of impoverished men, women, and children, each with a defined specialty, scavenged the dregs of the metropolis. There were toshers in the sewers and mudlarks on the riverbanks, rag-pickers atop rubbish heaps and bone-pickers behind kitchens. "Pure-finders" scooped up dog manure for tanneries, dustmen collected ash and night-soil men emptied cesspools. . . . Teeming cities like London and Paris could not have functioned without the ad hoc scavenging system, but the cost was very high. The scavengers worked in filth, and as the investigations of William Farr and John Snow demonstrated, filthy conditions were crucial in the spread of communicable disease.
