It will then be found to be an ultimately beneficial effect of the removal of the circumstances by the adoption of such modes of cleansing as diminish the prevalent amount of filth or filthy processes, that it will force a change to other occupations of a less degrading character, and diminish the number of persons “brought up” to them. Any provision of the nature of a poor law may be said to be badly constructed which does not allow the exercise of a discretionary authority to alleviate any severe inconveniences to the poorest classes from such changes. For the sake of preventing the growth of the like misery, it would probably be found a good civic economy to maintain the whole of the existing class in idleness, if idleness were not in itself a curse to them. I mention this, because the parish officers frequently oppose improved modes of paving and efficient cleansing, (as they generally opposed the new police on the ground that it diminished the means of subsistence of decrepit old men as watchmen,) for the avowed reason that it is expedient to keep the streets in their present state of filth in order to keep up the means of employing indigent persons as street-sweepers and sweepers of crossings in removing it. It is found in the metropolis to be a beneficial result of the increase of the practice of removing night-soil by the self-acting process of water-closets communicating with the sewers, that it prevents the increase of the number of nightmen formerly requisite for the performance of that offensive and dangerous labour, and is in the metropolis diminishing the number. Yet it should be borne in mind, that until more complete measures are adopted, even the services of such agents are an improvement, and in crowded cities are only neglected at the expense of the degradation of the whole mass of the labouring population. An example is to be found in the state of some districts mentioned by _Dr. Speer_, who in his account of the diseases of the lower orders in Dublin, given in the Dublin Hospital Reports, noticed the fact that the fever cases always came from the filthy districts; and he observes,
