There is no map of the general sewerage of the metropolis, merely “sections” and “plans” of improvements making or suggested, in the reports of the surveyors, &c., to the Commissioners; but did a map of subterranean London exist, with its lines of every class of sewerage and of the drainage which feeds the sewers; with its course, moreover, of gas-pipes and water-pipes, with their connection with the houses, the streets, the courts, &c., it would be the most curious and skeleton-like map in the world.
Of the Subterranean Character of the Sewers.
In my inquiries among that curious body of men, the “Sewer Hunters,” I found them make light of any danger, their principal fear being from the attacks of rats in case they became isolated from the gang with whom they searched in common, while they represented the odour as a mere nothing in the way of unpleasantness. But these men pursued only known and (by them) beaten tracks at low water, avoiding any deviation, and so becoming but partially acquainted with the character and direction of the sewers. And had it been otherwise, they are not a class competent to describe what they saw, however keen-eyed after silver spoons.
The following account is derived chiefly from official sources. I may premise that where the deposit is found the greatest, the sewer is in the worst state. This deposit, I find it repeatedly stated, is of a most miscellaneous character. Some of the sewers, indeed, are represented as the dust-bins and dung-hills of the immediate neighbourhood. The deposit has been found to comprise all the ingredients from the breweries, the gas-works, and the several chemical and mineral manufactories; dead dogs, cats, kittens, and rats; offal from slaughter-houses, sometimes even including the entrails of the animals; street-pavement dirt of every variety; vegetable refuse; stable-dung; the refuse of pig-styes; night-soil; ashes; tin kettles and pans (pansherds); broken stoneware, as jars, pitchers, flower-pots, &c.; bricks; pieces of wood; rotten mortar and rubbish of different kinds; and even rags. Our criminal annals of the previous century show that often enough the bodies of murdered men were thrown into the Fleet and other ditches, then the open sewers of the metropolis, and if found washed into the Thames, they were so stained and disfigured by the foulness of the contents of these ditches, that recognition was often impossible, so that there could be but one verdict returned—“Found drowned.” Clothes stripped from a murdered person have been, it was authenticated on several occasions in Old Bailey evidence, thrown into the open sewer ditches, when torn and defaced, so that they might not supply evidence of identity. So close is the connection between physical filthiness in public matters and moral wickedness.
The following particulars show the characteristics of the underground London of the sewers. The subterranean surveys were made after the commissions were consolidated.
“An old sewer, running between Great Smith-street and St. Ann-street (Westminster), is a curiosity among sewers, although it is probably only one instance out of many similar constructions that will be discovered in the course of the subterranean survey. The bottom is formed of planks laid upon transverse timbers, 6 inches by 6 inches, about 3 feet apart. The size of the sewer varies in width from 2 to 6 feet, and from 4 to 5 feet in height. The inclination of the bottom is very irregular: there are jumps up at two or three places, and it contains a deposit of filth averaging 9 inches in depth, the sickening smell from which escapes into the houses and yards that drain into it. In many places the side walls have given way for lengths of 10 and 15 feet. Across this sewer timbers have been laid, upon which the external wall of a workshop has been built; the timbers are in a decaying state, and should they give way, the wall will fall into the sewer.”
From the further accounts of this survey, I find that a sewer from the Westminster Workhouse, which was of all shapes and sizes, was in so wretched a condition that the leveller could scarcely work for the thick scum that covered the glasses of the spirit-level in a few minutes after being wiped. “At the outfall into the Dean-street sewer, it is 3 feet 6 inches by 2 feet 8 inches for a short length. From the end of this, a wide sewer branches in each direction at right angles, 5 feet 8 inches by 5 feet 5 inches. Proceeding to the eastward about 30 feet, a chamber is reached about 30 feet in length, from the roof of which hangings of putrid matter like stalactites descend three feet in length. At the end of this chamber, the sewer passes under the public privies, the ceilings of which can be seen from it. Beyond this it is not possible to go.”
“In the Lucas-street sewer, where a portion of new work begins and the old terminates, a space of about 10 feet has been covered with boards, which, having broken, a dangerous chasm has been caused immediately under the road.”
“The West-street sewer had one foot of deposit. It was flushed while the levelling party was at work there, and the stream was so rapid that it nearly washed them away, instrument and all.”
There are further accounts of “deposit,” or of “stagnant filth,” in other sewers, varying from 6 to 14 inches, but that is insignificant compared to what follows.
