“We ought not to encourage a permanent day and night population underground,” Herbert Morrison stated in the autumn of 1944. “If that spirit gets abroad we are defeated.” The prospect of defeatism was not the only concern. It was also noticed that the experience of living underground encouraged an anti-authoritarian and egalitarian spirit, as if the conditions above the ground could be reversed. Here, out of sight, radicalism might flourish; one newsletter which circulated among the subterraneans denounced the wartime authorities for “indifference amounting almost to callousness, neglect, soulless contempt for elementary human decencies.” So those under the ground instilled an element of fear in those who remained above it; it resembles the ancient superstitious fear of the miner, as an emblem of the dark world in which he works. It is the fear of the depths.
There are more recent accounts of the honest flushers and gangers who are gainfully employed to clear the sewers of soft mud and grit. A newspaper account of 1960 reports, of a Piccadilly sewer which drained into the Tyburn, that “it was like crossing the Styx. The fog had followed us down from the streets and swirled above the discoloured and strong-smelling river like the stream of Hades.” So the descent conjures up mythological imagery. Eric Newby descended into the sewer of the Fleet and “seen fitfully by the light of miners’ lanterns and special lamps, it was like one of the prisons designed by Piranesi.” Again the imagery of the prison emerges. One sewerman told an interested guest below: “You should see some of ’em under the City. They’re medieval. They don’t show ’em to visitors.” In that medieval spirit we read then of a “cavernous chamber … with pillars, arches, and buttresses, like a cathedral undercroft.” It is a strange city beneath the ground, perhaps best exemplified by worn manhole covers which, instead of reading SELF LOCKING, spell out ELF KING.
