boiler chimneys emitted black, opaque smoke for over ten minutes in the
hour. Yet the convictions for smoke nuisance were ludicrously few: in one year,
there was only one, and the average is three per annum, with a fine of s.
each.’

By the earlier twentieth century, then, remarkably little had been done to
reduce the regular and debilitating incidence of smoke fog in either London or
the great manufacturing centres. Fortuitously, however, the Edwardian era wit-
nessed what is perhaps most accurately described as an autonomous meteorolog-
ical improvement.

But relief was short-lived. As the First World War drew to
a close, the capital was again shrouded in impenetrable fog during February,
. Nor was there any radical improvement during the interwar years. Foggy
episodes were shorter than they had been between and , and fog-
related deaths from bronchitis, pneumonia and asthma seemingly less numerous.
But on four occasions during the s, and four more in the s, London
was paralysed.

Whether a similar pattern was reproduced in the urban North
of England, and in industrial Scotland and Wales, is unclear. Prolonged depres-
sion certainly seems likely, in itself, to have produced precisely those relatively
smoke-free skies that had earlier been feared and decried as symbols of commu-
nal unemployment and poverty. But, for those in work, coal was plentiful and
cheap and the attractions of a roaring, and smoky, hearth no less seductive.
Observers travelling through and reporting on the state of industrial Britain
during the s still frequently referred to ubiquitous smoke and fog; and so,
also, did pressure groups campaigning for tighter legislative control.

Progressives might sing the praises of clean electricity, but working-class sectors
of British cities were still heavily dependent on coal for the purpose of domes-
tic heating.
In the immediate aftermath of the Second World War, the capital experienced
yet another severe fog cycle with excess deaths reportedly rising by between
November and the beginning of December , and, astonishingly, by no
fewer than , during the terrible darkness that descended on the city between
