1748                           LAWS OF MARYLAND                      [CH. 819

provided for in this subheading. In making the calculation to deter-
mine compliance with the limitation contained in this subsection, the
Commission may make the following assumption: (i) continued future
levy of said tax or taxes at the rate of [seven cents (7¢)] ten cents
(10¢) NINE CENTS (9¢) IN MONTGOMERY COUNTY AND
SEVEN CENTS (7¢) IN PRINCE GEORGE'S COUNTY per one
hundred dollars ($100.00) of assessed value; (ii) that there will be
one hundred per centum (100%) collection of said tax in each fiscal
year and that the assessed value of property at the time any such
bonds are issued will remain constant.

(d) Guarantee of principal and interest on bonds.—(1) The
bonds shall be issued upon the full faith and credit of the Commis-
sion and of the county or counties guaranteeing them as hereinafter
provided. The principal and interest thereof shall be primarily
payable from the proceeds of the levy of tax or taxes of [seven cents
(7¢)] ten cents (10¢) NINE CENTS (9¢) IN MONTGOMERY
COUNTY AND SEVEN CENTS (70) IN PRINCE GEORGE'S
COUNTY which each county is herein authorized and empowered
to levy upon each one hundred dollars ($100.00) of assessed val-
uation of property lying within that portion of the District in
each county, respectively. (2) Any such bonds shall be issued
under the hand and seal of the Commission and shall be guar-
anteed as to the payment of principal and interest in the follow-
ing manner: in the event that the Commission resolves to ex-
pend the proceeds of any series of such bonds throughout the
District, the said bonds shall be guaranteed to the payment of
principal and interest by the County Commissioners of Prince
George's County and by Montgomery County. The guarantee shall
be endorsed on each of said bonds in the following language: "The
payment of interest when due and of the principal on maturity is
guaranteed by Montgomery and Prince George's Counties, Mary-
land." Such endorsement shall be signed on each of the bonds by
the President and Secretary or the clerk or other executive head
of the County Commissioners or the County Council, as the case
may be, within twenty (20) days after the bonds are presented by
the Commission to them for endorsement.

(h) Expenditures of proceeds of bonds.—In the event the said
proceeds of a series of such bonds are to be expended throughout
the District, the proceeds of the sale of bonds issued under this
subheading shall be expended in that portion of each county within
the District in such proportion as the assessable basis of such portion
of either county bears to the assessable basis of the whole of said
District. However, the Commission may issue such bonds for carry-
ing out its corporate purposes in that portion of the District within
either county, the principal and interest to be guaranteed by and
payable as provided in this subheading from the [seven cents (7c)]
ten cents (10¢) NINE CENTS (9¢) tax IN MONTGOMERY COUN-

TY AND SEVEN CENTS (7¢) IN PRINCE GEORGE'S COUNTY
levied by the county benefited. The proceeds of the sale of bonds
issued under this section to be expended within or for the benefit of
that portion of the District within Montgomery County shall be ex-
pended only upon the recommendation of the members of the Com-
mission from Montgomery County. In like manner, the proceeds of
the sale of bonds issued to be expended within that portion of the
District within Prince George's County shall be expended only upon
