property may, at his option, within one year from the time
said front foot assessment or benefit charge is levied, extin-
guish the same by the payment in cash in one sum of the pro-
portion of the estimated cost of the project, of which the con-
struction abutting upon his property is a part, represented by
the number of front feet which he is assessed with interest
at the rate of six per cent, per annum from the date of such
levy, less any annual payment that may have been made there-
on. ''The Commissioners of Vienna," in estimating the said
cost for the purpose of extinguishment, may add thereto a
reasonable margin to protect themselves against possible changes
in the cost of construction and loss of interest. All sums re-
ceived under such plan of extinguishment shall be preserved
intact by "The Commissioners of Vienna" and applied to-
ward the payment of the interest on said bonds and toward the
redemption of one bond in each and every year beginning two
years after date of said issue, as hereinbefore provided; and
provided further, that any property owner whose property is
classified under business or industrial, or sub-division, may,
at his option, at any time during the life of said assess-
ment, extinguish the same by payment in cash of an amount,
which, if put at interest at 3 1/2 per cent, compounded annu-
ally, would yield an annuity equal to the annual assessment
for the period for which said assessment has yet to run. "The
Commissioners of Vienna" shall at any time permit a connec-
tion with a water main by a property owner whose property
does not abut on said water main and who has not previously
thereto paid an assessment for the construction of said water
main, provided the said "The Commissioners of Vienna" shall
first determine the classification of said property, and a front
foot charge to be paid by said property owner, as though his
property abutted on said water main; and in the event of such
connection being made, said property owner and said prop-
erty, as to all charges, rates and assessment, shall in every
respect stand in the same position as if the said property abut-
ted upon a water main. The annual assessments as above
specified shall be a first lien upon the property against which
they are assessed, subject only to prior state, county and mu-
nicipal charges, and shall be enforced by a judgment upon com-
plaint of the authorities of Vienna before .any justice of the
peace or the Circuit Court of Dorchester County, and usual
execution thereof. No such annual assessment shall continue
as a lien for a period longer than three years from the date
from which the same became in default, unless it is reduced
