Section 335, and, to the extent necessary, by a levy annually
against all taxable property, in the water, sewerage or drain-
age sub-district as hereinbefore provided for such amount,
less the connection charges and front foot assessments on
hand and/or estimated to be received during such year
applicable to the payment of interest and retirement expenses,
for all the bonds issued to defray the cost of the water, sewerage
or drainage sub-district so improved or benefited, provided that
in the event such sum so levied on the water, sewerage or drain-
age sub-district shall not provide a sufficient sinking fund to
retire all such bonds, as they mature, then the Commissioners
shall levy annually against all taxable property in Baltimore
County a sufficient sum to make up the deficiency. The Treas-
urer of Baltimore County is hereby required to collect the tax
SO' levied, in the same manner as State and county taxes are
collected, and such tax shall bear the same interest and be sub-
ject to the same penalties in the event of non-payment, as in
the ease of other county taxes. From the money so received,
together with the amount in hand to the credit of said bond
fund from the collections provided for in Section 9, the Com-
missioners shall first pay all interest on said bonds as it matures,
and shall then deposit in some bank, or banks in Baltimore
County to the credit of the Commissioners, as a fund to be known
as the "Sinking Fund Account, " the amount so raised for the
payment of the principal of said bonds. The monies in the Sink-
ing Fund shall be kept entirely separate from all other monies
of the said Commissioners and of the county, and the said Com-
missioners shall invest the monies in the Sinking Fund in the
purchase of any bonds issued under this Act when they are
obtainable at not exceeding one point above the issue price or
in bonds of the United States Government or of the State of
Maryland; and bonds issued under this Act when purchased for
the Sinking Fund shall not be cancelled and destroyed, but shall
be immediately stamped to show that they belong to the Sinking
Fund and shall be held and treated as1 other outstanding bonds-
bearing interest, and the interest thereon shall be paid into the
Sinking Fund until their maturity and at maturity they shall
be cancelled at the1 same time at which bonds of the same series
outstanding in the hands of the public are paid. The Commis-
sioners shall have power and authority to sell any United States
or State of Maryland bonds at any time in the Sinking Fund
in order to provide cash to pay any series of bonds issued under
this Act as they mature or to purchase with the proceeds bonds
issued under this Act whenever the Commissioners can in their
judgment make such a change of investment advantageously.
The provisions of this section shall not apply to the properties,
plants, franchises, and/or rights of the Mayor and City Coun-
cil of Baltimore or to any properties, plants, franchises and/or
