211F. Taxes to cover payment of principal and interest; sinking
fund.

For the payment of the principal of and the interest on the bonds
issued pursuant to Section 211A of this subheading, as such principal
and interest shall become due and payable, there shall be and is hereby
laid an annual tax which shall consist of the following: (1) Such

vehicles imposed by the Acts of the 1964 Session of the General As-
sembly of Maryland; (2) such amounts as may be necessary of that
portion of the additional 1¢ a gallon increase in the gasoline tax
fund imposed under the Acts of the 1964 Session of the General As-
sembly of Maryland and allocated to the Commission. The taxes
imposed by items (1) and (2) above shall be, to the extent necessary,
exclusively used for the payment of the principal and interest on the
bonds authorized by Section 211A of this Article. So long as any of
the bonds issued pursuant to the authority of Section 211A of this
subheading shall remain outstanding and unpaid, there shall be de-
posited in a sinking fund to be established by the Commission to
secure the payment of the principal and interest of said bonds, annu-
ally or oftener as received, so much of the proceeds of the taxes laid
under this section as shall be necessary to maintain in said sinking
fund a sum equal to the amount required to pay the principal of and
the interest on such of the bonds as shall be then outstanding, which
will become payable in the current calendar year and in the next
succeeding calendar year. Said proceeds are hereby irrevocably
pledged to the payment of the principal of and interest on the bonds
issued pursuant to the authority of Section 211A of this subheading,
as the same shall become due and payable, and such taxes, to the ex-
tent hereby required, shall not be repealed, diminished or applied to
any other object until such bonds and the interest thereon shall be
fully paid or until adequate and complete provision for such payment
shall have been made.
