If a woman does not wish to be dealt with as a half-hearted murderess she should not behave like one. It should also be punishable on the part of a mother to leave children below a certain age alone for longer than a certain interval. It is absurd to punish people as we do, for the injuries inflicted by them upon their children during uncontrollable anger, and not to punish them for the injuries inflicted by uncontrolled carelessness. Such legislation should ensure children space, air and attention. [Footnote: It is less within the range of commonly grasped ideas, it is therefore less within the range of practical expedients, to point out that a graduated scale of building regulation might be contrived for use in different localities. Districts could be classed in grades determined by the position of each district in the scale of infant mortality, and in those in which the rate was highest the hygienic standard could be made most stringent and onerous upon the house owner. This would force up the price of house-room, and that would force up the price of labour, and this would give the proprietors of unwholesome industries a personal interest in hygienic conditions about them. It would also tend to force population out of districts intrinsically unhealthy into districts intrinsically healthy. The statistics of low-grade districts could be examined to discover the distinctive diseases which determine their lowness of grade, and if these were preventable diseases they could be controlled by special regulations. A further extension of these principles might be made. Direct inducements to attract the high birth-rates towards exceptionally healthy districts could be contrived by a differential rating of sound families with children in such districts, the burthen of heavy rates could be thrown upon silly and selfish landowners who attempted to stifle sound populations by using highly habitable areas as golf links, private parks, game preserves, and the like, and public-spirited people could combine to facilitate communications that would render life in such districts compatible with industrial occupation. Such deliberate redistribution of population as this differential treatment of districts involves, is, however, quite beyond the available power and intelligence of our public control at present, and I suggest it here as something that our grandchildren perhaps may begin to consider. But if in the obscurity of this footnote I may let myself go, I would point out that, in the future, a time may come when locomotion will be so swift and convenient and cheap that it will be unnecessary to spread out the homes of our great communities where the industrial and trading centres are gathered together; it will be unnecessary for each district to sustain the renewal and increase of its own population. Certain wide regions will become specifically administrative and central--the home lands, the
