animal substance
Animal fats historically used as domestic fuels include whale, shark, and seal oil. The narrator later reports that “The vexed question of light was settled by buying a quantity of bayberry wax for candles; and, on discovering that no one knew how to make them, pine-knots were introduced, to be used when absolutely necessary.” (1560)
