in conjunction with any amounts as the Commission may estimate
that it will be able to collect out of the benefit assessments therefor
levied by it but not yet paid and any further funds then available
for the purpose, to meet the interest on said bonds as it becomes due
and to pay the principal thereof as the bonds mature, and said tax
shall be determined, levied, collected and paid over in the manner
following, that is to say, at least sixty days before the tax levying
period of each year, the County Commissioners shall certify to the
Metropolitan Commission the whole valuation of the assessable prop-
erty within each sanitary district. The Commission shall then deter-
mine in the manner above prescribed the amount which it deems
necessary to be raised during the ensuing year for the payment of
interest and principal of all serial bonds maturing in said year, and
after deducting all amounts in hand or in contemplation applicable
to payments of interest and principal on said bonds as hereinbefore
and hereinafter in the sub-title provided; it shall determine the num-
ber of cents per $100.00 necessary to raise the said amount for each
such sanitary district and shall certify the same to the Board of
County Commissioners. The said County Commissioners in their
next annual levy shall levy said tax on all land and improvements and
all other property assessed for county tax purposes within the re-
spective sanitary district, which tax shall be levied and collected and
have the same priority rights, bear the same interest and penalties
and in every respect be treated the same as county taxes. The tax
so levied for the ensuing year shall be collected by the tax collecting
authorities and every sixty days they shall remit the whole amount
of the tax so collected to the Commission. From the money so re-
ceived, together with the amount in hand to the credit of said bond
fund, the Commission shall first pay all interest and principal on said
bonds as it becomes due, 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. 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 in-
terest may be so expended.

In order that the prompt payment of interest and the proper pro-
vision for the payment of the principal of said bonds shall be assured,
the prompt and proper performance of the respective acts and duties
heretofore defined is specifically enjoined, and any failure upon the
part of any person, persons, body corporate or agent to perform the
necessary acts and duties hereafter set forth, to pay over the said
funds as required, or to use said funds or any part thereof for any
other purpose than for the payment of the principal and interest on
said bonds, is hereby declared a misdemeanor and punishable as other
misdemeanors are punishable by Section 21 of this sub-title.

181. Whenever the plans and specifications for water supply,
sewerage or drainage systems for any sanitary district shall have
been completed and the Commission shall have decided after oppor-
tunity for a hearing has been given to proceed with the construction
thereof, it shall advertise, by notice in one newspaper published in
St. Mary's County and such newspapers and technical 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 judgment may appear advis-
able. 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 re-advertise
