It may be that the legislature should be asked to confer upon the city additional powers that would enable it to acquire property for railway terminals and appropriate connections to be used by the various transportation lines on just terms. A city cannot condemn land for the purpose of turning it over to a railway corporation, but there can be little doubt of the power of the legislature to authorize a city to condemn land in order to create a central clearing place for traffic. Chapter 247 of the Acts of the legislature of Wisconsin for the year 1907 is an example of a law designed for that end. This statute authorizes cities of the first class to acquire, establish, own and operate railway terminals, and to condemn land for that purpose. Having established such a terminal, the city may permit any railroad corporation to use it upon agreed terms, or, if the parties cannot agree, then upon terms to be fixed by the state railroad commission. To meet the first cost, the city is authorized to issue “railway terminal certificates,” payable only out of the revenues derived from the terminals for the acquisition of which they are issued. These certificates may be secured by trust deed, and there are provisions for foreclosure similar in many respects to those contained in the so-called “Mueller Law” enacted by the legislature of Illinois, authorizing municipal ownership of street railways. Under the decision of the Supreme Court of Illinois,[73] such certificates would constitute “indebtedness” of the city, and the amount which could be issued at any time would be controlled by the constitutional limitation of municipal indebtedness. That municipal certificates or bonds secured by revenue-producing utilities and not made a charge upon the other property or general credit of the city should be exempted from the general constitutional debt limit is advocated by men of widely different opinions upon the public-utility question,[74] and is provided in various state constitutions.[75] Constitutional amendments to this effect are being proposed in New York and elsewhere. CONTROL OF LANDS ADJACENT TO PUBLIC IMPROVEMENTS In order to secure the full benefit of a park, boulevard, avenue or other place of public recreation or resort, some control of the immediate surroundings is indispensable. The municipal authorities which establish parks, boulevards, and other public places need some power to regulate the use of premises within immediate view of the public grounds, so as to prevent offensive advertising, restrict the kinds of business, if any, to be conducted thereon, and make appropriate regulation of the height, manner of construction, and location of the surrounding buildings. To that end, resort must be had either to the police power or to the power of eminent domain.
