be provided for smaller cities which must divide governmental power with a township government, a county government, and a drainage or a levee district, all operating in the same territory and all having a considerable list of elective officers, there is little hope for a real trial of the effect of the concentration of governmental power in a few elective offices to disrupt extra-legal government. It is of the utmost importance to the success of the commission form of government for smaller cities that such government be the only local government operating in the territory occupied by the city. In some cases, however, it is necessary that municipal corporations with special powers and functions and collecting taxes from a special district for a special purpose should occupy territory in which several other units of municipal government operate. For instance, the Sanitary District in Cook County properly levies taxes upon property in the city of Chicago and in part of Cook County, and builds a canal running through Cook County and Will County. How is it possible to avoid having the commissioners of such a sanitary district elected from the district where its revenues are obtained? The answer is very simple. Such commissioners should be appointed by the different municipal units of government occupying the territory included in the sanitary district. The city of Chicago, of course, should appoint the majority of the commissioners. The municipal governments outside the city of Chicago should be combined together in groups and the legislative bodies of the municipalities in each group be given a voice in the selection of commissioners for the Sanitary District. The same principle of appointment may be adopted whenever a special board with special functions is to occupy territory which includes several units of local government.
