Kenrick Watson, Transactions of the Provincial Medical and Surgical Association (1834)
“ The mud from the canals and basins, which consists principally of clay mixed with sand, more or less coal-dust, and a very small portion of animal and vegetable matter, is frequently allowed to remain in different parts of the town, for many weeks, until it is dry enough to be removed, but I never observed any disease arise from this cause. The labouring classes in the town are generally in comfortable circumstances, and their wages are good. Bargemen, when on a voyage, get an unlimited allowance of animal food and beer, with bread. ”
