a part of the social protective policy. The public interest undoubtedly is served by having these suffering classes sys tematically relieved, but the extent and nature of the pro vision are questions ever in debate. Still more debated is temperance legislation, both as to licensing and as to pro hibiting the liquor traffic. Nowhere is the manufacture and sale of intoxicating liquor treated quite like the traffic in most other goods, because it is recognized that the public in terest is affected in a different way. While it is beyond ques tion that society should protect itself and its innocent mem bers against the drunkard, it is more doubtful whether it owes to the man, for his sake, protection against his own blunders. Not even the gods can save the stupid. Temperance legis lation is strongest in its social aspect. The opponent of it usually champions the individualist view; its partizans uphold, in varying degrees, the social view.
Similar questions arise regarding lotteries, gambling, bet ting, and horse-racing. When a man backs a worthless horse against the field, money probably is transferred from the stupider to the shrewder party. The philosopher may say that the sooner a prodigal and his money are parted the bet ter; but the broken gambler remains a burden and a threat to honest society. Gambling, lotteries, and speculation cause em bezzlement, crime, unhappy homes, and wrecked Here are to be found with difficulty the true boundaries between ethics and expediency. A busybody despotism may protect the fool, but it thereby helps to perpetuate and multiply his folly ; yet, if the fool is left alone, he too often is a plague to the wise and the virtuous.
and twenty years before. The total number of persons liv ing in cities of 8000 had increased in more than double that ratio. In 1920, for the first time, the population classed as urban (in places with 2500 population or more) exceeded that Classed as rural, being 51.4 per cent of the total.
The rapid growth of urban communities brought many evils. Considered in their more material aspects, nearly all of these are summed up in the term, "housing problem." As population grows denser in cities, land rises in value, yards and gardens narrow and then disappear, light, sun, and air are shut out, and cleanliness, decency, and home life become more difficult and, for many, impossible. The resi
dents gradually group themselves in districts corresponding to their economic incomes, and the poorer parts of the popu lation become tenement dwellers in the neighborhood of fac tories or become segregated in "slum" districts of unsani tary and dilapidated houses.
Property-owners are in many communities limited as to height of buildings, appearance, and, by the zoning system, even the uses for which houses may be erected in any district. American cities have still much to learn in this regard from the example of many European cities, which have developed the art of city planning with wonderful results in beauty of landscape and of architecture, in practical economy for busi ness, and in the health and welfare of the mass of the people.
