Whenever the owners of three-fourths of the land comprising an industrial district shall file a petition with the board of county commissioners which incorporated said industrial district, praying for the dissolution of the same, it shall then be the duty of said board of county commissioners to fix forthwith a time and place for the hearing of such petition and to cause the county clerk to give notice thereof by one publication in some newspaper published and of general circulation in the county at least fifteen (15) days before the day fixed for hearing. At the time of said hearing, it shall be the duty of the board of county commissioners first to ascertain and determine whether the required notice has been published, and, if so, to hear all persons in favor or opposed to granting the prayer of the petition, and all evidence with respect as to whether or not such petition contains the proper number of signers prescribed by the act; and, if upon such hearing it shall be found and determined that such petition is sufficient, then such board of county commissioners may make a finding and decision approving the petition, and if such petition is approved, shall thereupon immediately make an order dissolving said industrial district. A copy of such order shall be filed with the secretary of state and with the register of deeds of the county in which the district was formed.

The records of such district shall be delivered to the county clerk, and if there be any debts unpaid of such industrial district at the time of its dissolution under the provisions of this act, then the board of county commissioners shall, at each succeeding annual levy of taxes, levy a tax on the property within the limits of such industrial district sufficient to pay such debt according to its terms in the same manner as taxes are now levied for county purposes.
