In counties having a population of more than one hundred twenty-five thousand and having an assessed tangible valuation of more than one hundred fifty million dollars, the board of county commissioners is hereby authorized and empowered to issue the bonds of such county in an amount not exceeding two hundred thousand dollars for the purpose of acquiring land to be donated to the federal government for an aircraft supply and repair depot for national defense purposes. Before any such bonds shall be issued, the question of issuing same shall be submitted to the vote of the people at a special election called for that purpose, and no bonds shall be issued until a majority of the qualified electors who shall vote on the question at such election, shall have declared by their votes in favor of issuing said bonds. All bonds authorized by this act shall be issued, sold, delivered and retired under the provisions of article 1 of chapter 10 of the Kansas Statutes Annotated, and amendments thereto, and none of the debt limitations provided by law shall apply to bonds issued under this act. The total amount of bonds issued under this act by any such county shall never exceed the sum of two hundred thousand dollars.
