rooms, though in reduced circumstances. When questioned as to why he had remained in Kennington instead of moving after his work, the man pointed out that the back rent would seem almost impossible to pay off at a distance. Then there was no one who knew them at Finsbury, where, should misfortune overtake them again, instead of being helped through a period of unemployment, they would have nothing before them but the “house.” It is obvious that, in London at any rate, the wretched housing, which is at the same time more than they can afford, has as bad an influence on the health of the poor as any other of their miserable conditions. If poverty did not mean wretched housing, it would be shorn of half its dangers. The London poor are driven to pay one-third of their income for dark, damp rooms which are too small and too few in houses which are ill-built and overcrowded. And above the overcrowding of the house and of the room comes the overcrowding of the bed—equally the result of poverty, and equally dangerous to health. Even if the food which can be provided out of 22s. a week, after 7s. or 8s. has been taken for rent, were of first-rate quality and sufficient in quantity, the night spent in such beds in such rooms in such houses would devitalise the children. It would take away their appetites, and render them more liable to any infection at home or at school. Taken in conjunction with the food they do get, it is no wonder that the health of London school-children exercises the mind of the medical officials of the London County Council.
