It is stated in one of the Reports of the Board of Health, that “unless cleansing be general and simultaneous, much of the dirt of one district is carried by traffic into another. By the subdivision of the metropolis into small districts, the duty of cleansing the public carriage-way is thrown upon a number of obscure and irresponsible authorities; while the duty of cleansing the public footways, which are no less important, are charged upon multitudes of private individuals.” [The grammar is the Board of Health’s grammar.] “It is a false pecuniary economy, in the case of the poorest inhabitants of court or alley, who obtain their livelihood by any regular occupation, to charge upon each family the duty of cleansing the footway before their doors. The performance of this service daily, at a rate of 1d. per week per house or per family, would be an economy in soap and clothes to persons the average value of whose time is never less than 2d. per hour.” [This is at the rate of 2s. a day; did this most innocent Board never hear of work yielding 1s. 6d. a week? But the sanitary authorities seem to be as fond as teetotallers of “going to extremes.”]
In another part of the same Report the process and results are described. It is also stated that for the success of this method of street purification the pavement must be good; for “a powerful jet, applied by the hose, would scoop out hollows in unpaved places, and also loosen and remove the stones in those that are badly paved.” As every public place ought to be well-paved, this necessity of new and good pavement is no reasonable objection to the plan, though it certainly admits of a question as to the durability of the roads—the macadamized especially—under this continual soaking. Sir Henry Parnell, the great road authority, speaks of wet as the main destroyer of the highways.
It is stated in the Report, after the mention of experiments having been made by Mr. Lovick, Mr. Hale, and Mr. Lee (Mr. Lee being one of the engineering inspectors of the Board), that
“Mr. Lovick, at the instance of the Metropolitan Commissioners of Sewers, conducted his experiments with such jets as could be obtained from the water companies’ mains in eligible places; but the pressure was low and insufficient. Nevertheless, it appeared that, taking the extra quantity of water required at the actual expense of pumping, the paved surfaces might be washed clean at one-half the price of the scavagers’ manual labour in sweeping. Mr. Lee’s trials were made at Sheffield, with the aid of a more powerful and suitable pressure, and he found that with such pressure as he obtained the cleansing might be effected in one-third the time, and at one-third the usual expense, of the scavagers’ labour of sweeping the surface with the broom.” [This expense varies, and the Board nowhere states at what rate it is computed; the scavagers’ wages varying 100 per cent.]
“The effect of this mode of cleansing in close courts and streets,” it is further stated, “was found to be peculiarly grateful in hot weather. The water was first thrown up and diffused in a thin sheet, it was then applied rapidly to cleansing the surface and the side walls, as well as the pavements.” Mr. Lovick states that the immediate effect of this operation was to lower the temperature, and to produce a sense of freshness, similar to that experienced after a heavy thunder-shower in hot weather. But there is nothing said as to the probable effect of this state of things in winter—a hard frost for instance. The same expedient was resorted to for cooling the yards and outer courts of hospitals, and the shower thrown on the windows of the wards afforded great relief. Mr. Lovick, in his Report on the trial works for cleansing courts, states:—
“The importance of water as an agent in the improvement and preservation of health being in proportion to the unhealthiness or depressed condition of districts, its application to close courts and densely-populated localities, in which a low sanitary condition must obtain, is of primary importance. Having shown the practicability of applying this system (cleansing by jets of water) to the general cleansing of the streets, my further labours have been, and are now, directed to this end.
“For the purpose of ascertaining the effect produced by operations of this nature upon the atmosphere, two courts were selected: Church-passage, New Compton-street, open at both ends, with a carriage-way in the centre, and footway on each side; and Lloyd’s-court, Crown-street, St. Giles’s, a close court, with, at one entrance, a covered passage about 40 feet in length: both courts were in a very filthy condition; in Church-passage there were dead decaying cats and fish, with offal, straw, and refuse scattered over the surface; at one end an entrance to a private yard was used as a urinal; in every part there were most offensive smells.
“Lloyd’s-court was in a somewhat similar condition, the covered entrance being used as a general urinal, presenting a disgusting appearance; the whole atmosphere of the court was loaded with highly-offensive effluvia; in the covered entrance this was more particularly discernible.
“The property of water, as an absorbent, was rendered strikingly apparent in the immediate and marked effects of its application, a purity and freshness remarkably contrasted to the former close and foul condition prevailing throughout. A test of this, striking and unexpected, was the change at different periods in the relative condition of atmosphere of the courts and of the contiguous streets. In their ordinary condition, as might have been expected, the atmosphere was purer in the streets than in the courts; it was to be inferred that the cleansing would have more nearly assimilated these conditions. This was not only the case, but it was found to have effected a complete change; the atmosphere of the courts at the close of the operations being far fresher and purer than the atmosphere of the streets. The effect produced was in every respect satisfactory and complete; and was the theme of conversation with the lookers-on, and with the men who conducted the operations.
“The expense of these operations, including water, would be, for—
