At the beginning of the seventeenth century numerous and various complaints issued from the polluted city. In 1603 Hugh Platt wrote a ballad, “A Fire of Coal-Balles,” in which he claimed that the fumes of sea coal damaged plants and buildings; seventeen years later James I was “moved with compassion for the decayed fabric of St. Paul’s Cathedral near approaching ruin by the corroding quality of coal-smoke to which it had long been subjected.” There was also the prevalent fear of fire; there can be no doubt that the sight and smell of smoke aroused instinctive fears of flame in the thoroughfares of the city.
John Evelyn, in his treatise entitled
Despite written records of great fogs in previous eras, it is commonly believed that nineteenth-century London created the foggy darkness. Certainly Victorian fog is the world’s most famous meteorological phenomenon. It was everywhere, in Gothic drama and in private correspondence, in scientific reports and in fiction such as
Half a million coal fires mingling with the city’s vapour, “partly arising from imperfect drainage,” produced this “London particular,” rising approximately 200 to 240 feet above street level. Opinions varied concerning the colour of the fogs. There was a black species, “simply darkness complete and intense at mid day”; bottle-green; a variety as yellow as pea-soup, which stopped all the traffic and “seems to choke you”; “a rich lurid brown, like the light of some strange conflagration”; simply grey; “orange-coloured vapour”; a “dark chocolate-coloured pall.” Everyone seemed to notice changes in its density, however, when it was sometimes interfused with daylight or when wreaths of one colour would mingle with another. The closer to the heart of the city, the darker these shades would become until it was “misty black” in the dead centre. In 1873 there were seven hundred “extra” deaths, nineteen of them the result of pedestrians walking into the Thames, the docks or the canals. The fogs sometimes came and went rapidly, their smoke and gloom blown across the streets of the city by the prevailing winds, but often they lingered for days with the sun briefly seen through the cold yellow mist. The worst decade for fogs was the 1880s; the worst month was always November.
“The fog was denser than ever,” wrote the author Nathaniel Hawthorne on 8 December 1855, “very black indeed, more like a distillation of mud than anything else; the ghost of mud, the spiritualised medium of departed mud, through which the departed citizens of London probably tread in the Hades whither they are translated. So heavy was the gloom, that gas was lighted in all the shop windows; and the little charcoal furnaces of the women and boys, roasting chestnuts threw a ruddy misty glow around them.” Again the condition of the city is likened to that of hell itself, but with the additional association that somehow the citizens are privately enjoying-and indeed are rather proud of-their hapless condition.
