Still easier is it for the states to interfere in the city governments. If the Union wishes to make new regulations for the state, the Federal Constitution has to be amended; while if the state wants to hold a tighter rein on city government it can do so directly, for, as we have seen, the cities derive all their powers from the state legislature. There is, indeed, considerable tendency now to restrict the privileges of cities, and much of this is sound, especially where the state authority is against open municipal corruption. The general tendency is increasing to give the state considerable rights of supervision over matters of local hygiene, industrial conditions, penal and benevolent institutions. The advantages of uniformity which accrue from state supervision are emphasized by many persons, and still more the advantage derived from handing over hygienic, technical, and pedagogical questions to the well-paid state experts, instead of leaving them to the inexperience of small districts and towns. There is no doubt that on these lines the functions of the state are being extended slowly but steadily.
Then again the cities and towns in their turn are tending to absorb once more such forces as are subordinate to them, and thus to increase the municipal functions. The fundamental principles which have dominated the economic life in the United States and brought it to a healthful development, leave the greatest possible play for private initiative; thus not very long ago it was a matter of course that the water supply, the street lighting, the steam and electric railways should be wholly in the hands of private companies. A change is coming into these affairs, for it is clearly seen that industries of this sort are essentially different from ordinary business undertakings, not only because they make use of public roads, but also because such plants necessarily gain monopolies which find it easy to levy tribute upon the public. In recent years, therefore, city governments have little by little taken over the water supplies, and tend somewhat to limit the sphere of other private undertakings of this sort—as, for instance, that of street-lighting. At the same time there is an unmistakable tendency for city and town to undertake certain tasks which are not economically necessary, and which have been left hitherto to private initiative. Cities are building bath-houses and laundries, playgrounds and gymnasiums, and more especially public libraries and museums, providing concerts and other kinds of amusements and bureaus for the registration of those needing employment; in short, are everywhere taking up newly arisen duties and performing them at public expense.
