SION FOR SUCH BONDS computed with relation to the absolute
maturity of the bonds in accordance with standard tables of bond
values, excluding, however, from such computation the amount of
any premium to be paid on the redemption of any bonds prior to
maturity. Said bonds shall be forever exempt from State, city and
county taxation. They shall be issued under the signature and seal
of the district and shall be guaranteed as to payment of principal
and interest by the county or counties in which said district lies,
which guarantee shall be endorsed on each of said bonds in the
following language: "The payment of interest when due and the

principal at maturity is guaranteed by........................ (corporate name of

body politic and corporate guaranteeing the bonds)......................., Mary-
land." Such endorsement shall be signed on each of said bonds by
the chief executive officer (or other officer designated by resolution
of the particular governing body) and by the clerk or secretary of
the particular governing body or bodies within ten days after the
bonds are presented by the commission to them for endorsement. In
the event the bonds are guaranteed by two or more counties pursu-
ant to the provisions of this subtitle, the liability of any one county
so guaranteeing the bonds shall be in such proportion as the assess-
able basis of that part of such county within the sanitary district or
sanitary districts for which the bonds are issued bears to the assess-
able basis of the whole of the sanitary district or sanitary districts
for which the bonds are issued. Such bonds, so endorsed, shall be, and
they shall so recite, unconditional general obligations of the county
or counties endorsing the same; and this subtitle shall be construed
as a specific grant of authority to any county to issue and sell such
bonds in the manner herein prescribed. At any time prior to the
issuance of any such bonds the governing body of a particular
county is hereby authorized and directed to furnish to the com-
mission a sum not exceeding twenty-five thousand dollars
($25,000.00) which shall be repaid out of the first available moneys
derived from the sale of the first bonds issued, if any.

654.

(e) The commission in any district is hereby authorized and
empowered to issue bonds to refund, pay or discharge all or any
part of its outstanding bonds, notes or other evidences of indebted-
ness, including interest thereon, issued to finance the acquisition or
construction of sewerage [or] , water or solid waste disposal
projects, including real property, or any part of such facilities.
The relevant provisions of this subtitle pertaining to bonds shall
be equally applicable in the authorization and issuance of such re-
funding bonds, including their terms, rates and other aspects
thereof.

656.

Whenever the plans and specifications for water [or] , sewerage
or solid waste disposal systems or acceptance facilities for any sani-
tary district shall have been completed and the commission shall
have decided, after opportunity for a hearing has been given pur-
suant to Section 652 (b) or 653 of this Article, to proceed with
the construction thereof, it shall advertise, by notice in one news-
paper published, or of general circulation, in the county or counties
where the sanitary district is located and such newspapers and
technical press as it may deem proper, for bids for the construction
