Almost without exception the poor bear the marks on their own body of their careless indifference to the laws of health and cleanliness. I do not believe that the poor are too bad to be mended, nor that they are too dirty to be taught the necessity and desirability of cleanliness. Those who suffer thus from sanitary mismanagement are not to be improved by calling them filthy, incorrigible, and worthless, but by kindly pointing out the evils which arise from their own carelessness, and suggesting remedies which they themselves can carry into operation. The very worst have some good in them, and by appealing to that good in a kindly, honest spirit we may arouse that laudable ambition of self-respect and self-help, which will do more to improve the sanitary and social condition of the needy poor than could be accomplished by extraneous help, if it did not secure the hearty sympathy and co-operation of the poor. Until the poor take an interest in their homes and feel a pride in preserving them clean, healthy, and comfortable, we shall always be hearing of and seeing the homes of the poor in a dilapidated condition. Flooring and doors will be used as firewood—sewers will be blocked up by materials that ought never to have been thrown down—dirt, filth, and all manner of rubbish will be allowed to accumulate—how is this to be remedied? To remedy this evil, mere obstructiveness and selfishness must get out of the way. The homes of the poor must be cleansed, repaired, and made comfortable; and then if cleanliness were made a condition of tenancy as I have had occasion before to suggest, it would go a long way to keep the property in repair. I feel confident that where tenants keep their rooms clean they acquire an interest in them, and do not destroy nor wilfully damage them. Further, every effort ought to be made to instruct the poor in the knowledge of the laws of health. Let it be clearly shown to them that dirt, disease, and poverty, are intimate companions, and that if they would escape from the bitter experience of poverty, they must each sweep before their own doors; then a future, gilded with the promise of a joyous hope, shall open up before their view. Dirt with all its disgusting associations shall be supplanted by cleanliness with all its cheering comforts; disease manifesting itself in the emaciated body, the anxious brow, the glazed eye, and shrivelled face, shall give place to joyous health, with firm elastic step, with ruddy face, bright sparkling eye, and the alacrity and pleasure with which labour and toil is welcomed. Poverty in all its intensified bitterness, when associated with disease shall give place to a comfortable competency. This and much more may justly be expected, if we sow aright the seeds of the science of life, and teach men the laws which govern their health and life. The proper study of mankind is man; a more comprehensive principle has seldom been enunciated. Man in all his relations is
