170 LAWS OF MARYLAND. [CH. 99

say, at least sixty days before the tax levying period of
each year, the County Commissioners shall certify to the
Sanitary Commission the whole valuation of the assessable
property within each sanitary district. The Commission
shall then determine in the manner above prescribed the
amount which it deem necessary to be raised during the en-
suing year for the payment of interest and the proportion-
ate part of principal of all outstanding bonds and the
amounts to be paid into the sinking fund for said bonds in
any one year to be determined by the usual table of re-
demption of bonds by annual deposit in a sinking fund on
interest, 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 Act provided, it shall determine the number of cents
per $100. 00 necessary to raise the said amount for each
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 respective sanitary district, which
tax shall be levied and collected and have the same priority
right, 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 tax col-
lecting authorities and every sixty days they shall remit the
whole amount of the tax so collected to the Commission.
From the money so received, together with the amount in
hand to the credit of said bond fund, the Commission shall
first pay 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 Com-
missioners and the Commission, as a joint fund to be known
as the "Sinking Fund Account, " which shall be retained
and utilized for payment 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, or the said Commission may pur-
chase its own bonds, with the consent of the Board of
County Commissioners. 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 other-
wise, such deficiency may be added to and collected in the
next year's tax, or the County Commissioners may levy
