all interest on said bonds as it matures, and shall then deposit
the residue of said moneys in some bank or banks in said
county to the joint credit of the County Commissioners and
the Commission, as a joint fund to be known as the "Sinking
Fund Account, " which shall be retained and utilized for pay-
ment of principal of said bonds as they respectively mature.
The Commission and the County Commissioners shall, from
time to time invest said sinking fund in any bond or bonds
in which savings or trust funds are authorized to be invested
by national banks of the U. S. Treasury Department. Should
receipts from said tax or other sources be inadequate to deposit
the year's sinking fund increment on said bonds by reason of
default or otherwise, such deficiency may be added to and col-
lected in the next year's tax, or the County Commissioners may
levy against all taxable property in Anne Arundel County a
sufficient sum to make up the deficiency. The Commission is
authorized to pay the interest on any bonds it may issue out
of the proceeds of the sale of said bonds, but not more than
one year's interest may be so expended.

431.    Whenever the plans and specifications for water sup-
ply, sewerage or drainage systems for any district shall have
been completed and the Commission shall have decided after
opportunity for a hearing has been given to proceed with the
construction thereof, it shall advertise by one newspaper pub-
lished in Anne Arundel County and such newspapers and tech-
nical press as it may deem proper for bids for the construction
of said system or systems, in part or as a whole, as in its judg-
ment may appear advisable. The contract shall be let to the
lowest responsible bidder, or the Commission may reject any
and all bids, and, if in its discretion the prices quoted are
unreasonable or unbalanced it may readvertise the work or any
part of it or may do any part or all of the work by day labor;
provided that at any time the Commission may, in its discre-
tion, expend by day labor for construction work an amount
not exceeding twenty-five hundred dollars without advertising
or receiving bids. All such contracts shall be protected by
such bonds, penalties and conditions as the Commission may
require, all of which shall be enforced in any court having
jurisdiction.

the sinking fund for the bonds issued by said Commission as
