For the purpose of defraying extraordinary expenses and making public improvements, or to meet casual deficits or failure in revenue, the state may contract debts never to exceed with previous debts in the aggregate one hundred thousand dollars, and no greater indebtedness shall be incurred except for the purpose of repelling invasion, suppressing insurrection, or defending thee state or the United States in war and provision shall be made by law for the payment of the interest annually, and the principal when due, by tax levied for the purpose or from other sources of revenue; which law providing for the payment of such interest and principal by such tax or otherwise shall be irrepealable until such debt is paid: provided, however, the state of South Dakota shall have the power to refund the territorial debt assumed by the state of South Dakota, by bonds of the state of South Dakota.
