The legislature shall provide by law, such a system of county finance, as
shall cause the business of the several counties to be conducted on a cash basis. It
shall also provide that whenever any county shall have any warrants outstanding and
unpaid, for the payment of which there are no funds in the county treasury, the
county commissioners, in addition to other taxes provided by law, shall levy a
special tax, not to exceed ten (10) mills on the dollar, of taxable property, as shown
by the last preceding assessment, for the creation of a special fund for the
redemption of said warrants; and after the levy of such special tax, all warrants
issued before such levy, shall be paid exclusively out of said fund. All moneys in the
county treasury at the end of each fiscal year, not needed for current expenses, shall
be transferred to said redemption fund.
