In order to make it possible to work out a system of local tax units adapted to the needs of the whole county, the county board of education of its own initiative shall fix the boundaries of any school tax district within its jurisdiction in which it is proposed to levy a local school tax. In making application for a special election in any such district, the county board of education shall submit a map made by the county surveyor, or other competent person, showing the boundaries of the school tax district for which a special tax levy is proposed, indicating the section or sections and ranges, together with the correct description of the boundaries of the said district for which a special tax levy is proposed. These maps shall also show the location of public utilities, such as power plants, railroad and telegraph lines, if any, in such districts, and the railroad mileage for each and every corporation having property therein. The county superintendent shall include a full and correct description of such boundaries in the minutes of the county board of education and shall also furnish a full and correct description of such boundaries, including a map, to the probate judge, who shall record the same in a book to be kept by him for that purpose also to the Department of Education and to the Department of Revenue or other board exercising corresponding powers, including as many copies of such map as there are public utilities.
