The Sewer-hunter
The Sewer-hunter The sewer-hunters are again distinct, and a far more intelligent and adventurous class; but they work in gangs. They must be familiar with the course of the tides, or they might be drowned at high water. They must have quick eyes too, not merely to descry the objects of their search, but to mark the points and bearings of the subterraneous roads they traverse; in a word, “to know their way underground.” There is, moreover, some spirit of daring in venturing into a dark, solitary sewer, the chart being only in the memory, and in braving the possibility of noxious vapours, and the by no means insignificant dangers of the rats infesting these places.
