The board of supervisors in making the annual tax levy, as heretofore provided, shall take into account the maturing bonds and interest on all bonds and make provision in advance for the payment thereof. In case the proceeds of the original tax levy made under the provisions of § 49-19-1610 are not sufficient to pay the principal and interest on all bonds issued the board of supervisors shall make such additional levy or levies upon benefits assessed as are necessary for this purpose and under no circumstances shall any tax levies be made that will in any manner or to any extent impair the security of the bonds or the fund available for the payment of the principal and interest of thereof.
