Examples of the enormous benefit inseparable from well-considered sanitary legislation could be multiplied; though, on the other hand, it is also necessary to check optimism by many illustrations of the grievous harm still being wrought by want of thought. Hindrance to possible progress is also associated with the ignorance of those whose development has not yet attained the level when freedom of action can be permitted. It is some of the results of this ignorant indolence which cause the minds of the thoughtful and far-sighted to be tense with anxiety for the welfare of their country, and arouse a wish for further and more stringent public health enactments. Nevertheless, again it must be said that to legislate in advance of public opinion is futile. Only after stupendous exertion, for instance, has the serious and continued mortality among infants excited general attention; and the curious, widespread indifference to the recommendations of recent Royal Commissions on the Poor Law and the Care of the Feeble-minded indicates that, were infant mortality controllable by legislation, such legislation would still fail of its object unless it were also realised that a child's hold on life is practically dependent upon parental care, and is intimately associated with maternal nutrition before its birth. Or again; the law relating to the protection of the public food supply is approaching a high pitch of excellence; the penalties on adulteration or on the sale of diseased or otherwise unwholesome foodstuffs are severe and quite frequently inflicted; _but_ these regulations are powerless to influence the errors of nutrition constantly reflected in the features of our population at each age period, neither can they stem the tide of self-indulgence, emotionalism and luxury which enervate and deteriorate thousands of our people. Vain indeed are their endeavours to disguise by alcoholism and drugs the traces of their misfortunes. Stern Nature is relentless; her laws are as those of the Medes and Persians; the children's teeth _shall_ be set on edge by the fruits of the reckless folly and intemperance of their ancestors. Is sanitary legislation therefore a failure, or by what means can light from the sun of knowledge penetrate this dense mass of ignorance and apathy? For what reason has it opposed such a resistant surface to the manipulations of the reformer or to the coercions of the official? These questions do not, unfortunately, admit of concise or conclusive replies. Each political party in turn points the finger of reproach and derision at its opponents for the modest success by which their legislative efforts at social reforms are attended. Disease, malnutrition, alcoholism and overwork continue to hamper their efforts, and will continue so to do, until a sanitary conscience is awakened in each breast, at an age when habits and ideals are still unformed.
