and paid over in the manner following, that is to say, at least sixty
days before the tax levying period of each year, the governing body
shall certify to the 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 deems
necessary to be raised during the ensuing year for the payment of
interest and principal of all bonds maturing in said year, and after
deducting all amounts in hand or in contemplation applicable to pay-
ments of interest and principal on said bonds as hereinbefore and
hereinafter in this sub-title provided, it shall determine the number
of cents per $100.00 necessary to raise the said amount for each such
sanitary district and shall certify the same to the governing body.
The said governing body 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 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 respective tax collecting authorities and every
sixty days they shall remit the whole amount of the tax so collected
to the Commission. Prom the money so received, 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 the same become
due, and shall then deposit the residue of said moneys in some bank
or banks in the County where said district is located to the joint
credit of the county and the Commission. The Commission is author-
ized 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 interest may
be so expended.]

suing fiscal year of the County;
