fund to be known as the "Sinking Fund Account, " the amount
so raised for payment of the principal of said bonds. Said Com-
mission and the respective 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 by the U. S. Treasury Department. Should
receipts from said tax or other sources be inadequate to de-
posit the principal payment on said bonds, by reason of de-
faults or otherwise, such deficiency shall be added to and col-
lected in the next year's tax. The said Commission is author-
ized to pay the interest on any bonds it may issue prior to the
first tax levying period out of the proceeds of the sale of said
bonds. In order that the prompt payment of interest and the-
proper provision 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, per-
sons, 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 in-
terest on said bonds, is hereby declared a misdemeanor and
punishable as other misdemeanors are punishable by Section
21 of this Act.

SEC. 7. And be it further enacted, That whenever the plans
and specifications for water supply, sewerage or drainage sys-
tems for any district shall have been completed and said Com-
mission shall have decided, after opportunity for a hearing has
been given, to proceed with the construction, it shall advertise,
by notice in such newspapers and technical press as it may
deem proper, for bids for the construction of said system or
systems, in parts or as a whole, as in its judgment may appear
advisable. The contract shall be let to the lowest responsible
bidder, or the Commission may reject any or all bids and, if
in its discretion the prices quoted are unreasonable, 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, at its discretion, expend by day labor for
construction work an amount not exceeding $1, 000 without
advertising or receiving bids. All such contracts may be pro-
tected by such bonds, penalties and conditions as the Commis-
sion shall require, all of which shall be enforceable in any
court having jurisdiction.
