five days after the expiration thereof, any persons inter-
ested in said improvements will be heard. After pub-
lic hearing, however, the decision of the Commissioners'
as to the areas to be included and improvements to be
carried out in any sub-district shall be final. Such sur-
veys, studies and plans shall be made in consultation and
co-operation with the Chief Engineer of Baltimore City.
Whenever plans shall have been completed for a water supply,
sewerage or storm-water drainage system, or any part thereof,
in any part of the District, the Commissioners shall proceed
to construct or cause to be constructed such systems, or parts
thereof, by contract, after public advertisement, or by day
labor, if no satisfactory contract can be made after public ad-
vertisement, as they may deem advisable, so that said system
or systems may be constructed at a minimum cost, provided,
however, that the cost of such work carried out by day labor
shall not exceed, at any one time, twenty-five hundred dollars
($2, 500. 00). And provided further, that no hearing or notice
and advertisement thereof shall be required in case all parties
interested in any particular extension of a water supply line
file with the Commissioners a request in writing for such
extension.

charge for overhead. The Public Service Commission of
Maryland is hereby authorized and directed to review,
upon application by the Commissioners, the cost of mak-
ing such extensions, and the findings of the Public Service
Commission shall be final except that there may be an appeal
to the courts from such findings as is provided by law in the
case of other determinations by the Commission. The Com-
missioners are hereby empowered, authorized and directed to
raise funds, as hereinafter provided, for the expenditures here
above authorized and directed, and to pay to the City of Balti-
more out of such funds from time to time such sum or sums
either in advance or as such work is done as may be necessary
to cover the cost of said work. The proper authorities of Bal-
timore City are hereby empowered, authorized and directed to
make installations of water supply service pipes to be con-
