Public sentiment has done something also, but very far from enough. As a rule, it has slumbered peacefully until some flagrant outrage on decency and the health of the community aroused it to noisy but ephemeral indignation, or until a dreaded epidemic knocked at our door. It is this unsteadiness of purpose that has been to a large extent responsible for the apparent lagging of the authorities in cases not involving immediate danger to the general health. The law needs a much stronger and readier backing of a thoroughly enlightened public sentiment to make it as effective as it might be made. It is to be remembered that the health officers, in dealing with this subject of dangerous houses, are constantly trenching upon what each landlord considers his private rights, for which he is ready and bound to fight to the last. Nothing short of the strongest pressure will avail to convince him that these individual rights are to be surrendered for the clear benefit of the whole. It is easy enough to convince a man that he ought not to harbor the thief who steals people's property; but to make him see that he has no right to slowly kill his neighbors, or his tenants, by making a death-trap of his house, seems to be the hardest of all tasks. It is apparently the slowness of the process that obscures his mental sight. The man who will fight an order to repair the plumbing in his house through every court he can reach, would suffer tortures rather than shed the blood of a fellow-man by actual violence. Clearly, it is a matter of education on the part of the landlord no less than the tenant.
