1110 LAWS OF MARYLAND [CH. 368

the cost of improvements herein authorized abutting such lots
to such an amount as shall be just and equitable. The cost of
improvements exempted as provided in this section shall be
included in the assessments to be made against the abutting
property included in the project, and such adjustments as
made by the Mayor and City Council of Hyattsville shall be
final and conclusive.

The Mayor and City Council of Hyattsville may contrib-
ute toward the cost of constructing storm drains under the
provisions of this sub-title, out of any funds properly

chargeable with such costs, a proportion thereof deemed in

their judgment to be commensurate with the benefit ac-
corded to the general public and to the City of Hyattsville
because of such storm drain construction as compared to

the benefit derived from such construction by the abutting

property owners assessable with such costs, provided that
such contribution of the City shall not exceed twenty-five

(25) per cent of the total cost of the construction of such

storm drainage project including in the whole upon which

such percentage is computed any portion of the cost thereof

which may be contributed by other public authorities, and

the ten-year payment plan provided in this sub-title shall
extend to and be accorded to the Mayor and City Council of
Hyattsville in regard to such contributions in the same
manner as accorded to property owners paying assessments

under this sub-title.

Such assessments when made shall constitute a tax lien upon
such abutting property and shall bear interest, at [the] a rate
not to exceed six per cent per annum, and the principal of
such assessments shall be payable in twenty equal semi-annual
instalments from the date of said assessment, and at the time
of the payment of each of the said instalments there shall
be due and payable the interest on such instalment and on
the balance of the principal then unpaid, and the owner or
owners of any property assessed or any one on his or their
behalf shall at any time have the right to anticipate by pay-
ment all instalments, with interest to date, of the assessment
not then due, and any assessment or part thereof remaining
due and unpaid shall be enforced and collected by the Mayor
and City Council of Hyattsville in the same manner as special
assessments are now enforced and collected as now or here-
after prescribed and required by law; and the Treasurer of
said City is charged with the custody of any moneys received
from the sale of said bonds or certificates of indebtedness as
above mentioned, and with the prompt collection and safe
keeping of the moneys arising from assessments upon roadbeds,
