The foregoing, then, is the pith of the first authentic account which has appeared in print of the actually surveyed condition of the subterranean ways, over which the super-terranean tides of traffic are daily flowing.
The account I have just given relates to the (former) Westminster and part of Middlesex district on the north bank of the Thames, as ascertained under the Metropolitan Commission. I now give some extracts concerning a similar survey on the south bank, in different and distant directions in the district, once the “Surrey and Kent.” The Westminster, &c., survey took place in 1848; the Kent and Surrey in 1849. In the one case, 72 miles of sewers were surveyed; in the other, 69⅛ miles.
“The surveyors (in the Surrey and Kent sewers) find great difficulty in levelling the sewers of this district (I give the words of the Report); for, in the first place, the deposit is usually about two feet in depth, and in some cases it amounts to nearly five feet of putrid matter. The smell is usually of the most horrible description, the air being so foul that explosion and choke damp are very frequent. On the 12th January we were very nearly losing a whole party by choke damp, the last man being dragged out on his back (through two feet of black fœtid deposits) in a state of insensibility.... Two men of one party had also a narrow escape from drowning in the Alscot-road sewer, Rotherhithe.
“The sewers on the Surrey side are very irregular; even where they are inverted they frequently have a number of steps and inclinations the reverse way, causing the deposit to accumulate in elongated cesspools.
“It must be considered very fortunate that the subterranean parties did not first commence on the Surrey side, for if such had been the case, we should most undoubtedly have broken down. When compared with Westminster, the sewers are smaller and more full of deposit; and, bad as the smell is in the sewers in Westminster, it is infinitely worse on the Surrey side.”
Several details are then given, but they are only particulars of the general facts I have stated.
The following, however, are distinct facts concerning this branch of the subject.
In my inquiries among the working scavagers I often heard of their emptying street slop into sewers, and the following extract shows that I was not misinformed:—
“The detritus from the macadamized roads frequently forms a kind of grouting in the sewers so hard that it cannot be removed without hand labour.
“One of the sewers in Whitehall and another in Spring-gardens have from three to four feet of this sort of deposit; and another in Eaton-square was found filled up within a few inches of the ‘soffit,’ but it is supposed that the scavengers (scavagers) emptied the road-sweepings down the gully-grate in this instance;” and in other instances, too, there is no doubt—especially at Charing Cross, and the Regent Circus, Piccadilly.
